This article’s guiding question is about bullet biting: When should compatibilists about moral responsibility bite the bullet in responding to stories used in arguments for incompatibilism about moral responsibility? Featured stories are vignettes in which agents’ systems of values are radically reversed by means of brainwashing and the story behind the zygote argument. The malady known as “intuition deficit disorder” is also discussed.

abstract This essay considers the moral status of certain practices that aim to enhance offspring traits. I develop an objection to offspring enhancement that draws on an account of the role morality of parents. I work out an account of parental ethics by reference to premises about child development and to observations about parenting culture in the United States. I argue that excellence in parenthood consists in a dual responsibility both to guide children toward the good life and to accept (...) them as they are. I conclude that prenatal manipulation of healthy and normal characteristics in human offspring fails to balance the dispositional extremes of control and restraint to which many parents today are susceptible. I apply this account of good parenting to the challenging case of height enhancement for short but otherwise healthy children. Finally, I reply to objections, first, about the phenomenology of bearing normative obligations to people who do not yet exist and, second, about the moral logic of criticizing embryo selection in the context of assisted reproduction when we accept child selection in the context of adoption.

In response to controversies about Attention Deficit Disorder and Ritalin, many alternative therapies have proliferated in professional and lay circles. This study examines alternative therapy discourse and asks whether these texts offer any real challenge to traditional discourses of medicalized motherhood. Indeed, alternative therapies employ most of medicine's discursive strategies, portraying mothers as inadequate and responsible for their children's problems and positioning the child as both at risk and a danger to society. Furthermore, the speculative causal factors and (...) the lengths to which mothers are encouraged to go in alternative therapy texts place a heavier burden on women than do traditional medical texts. Thus, while the medical treatment for ADD might be challenged, alternative therapy discourse supports the legitimacy of ADD as a diagnostic category, argues that its causes are personal and gendered, and claims that professional intervention remains the proper response.

Ritalin use has increased by 500 percent in the last five years. The reasons for this dramatic surge are rooted in changes and pressures in psychiatry and society at large.

BackgroundAttention Deficit Hyperactivity Disorder is one of the most prevalent psychiatric disorders among school-age children and is characterized by varying degrees of inattention, hyperactivity, and impulsivity. Diagnosis, which currently relies on the DSM-V criteria, is complex. This research proposes an integrated procedure for ADHD diagnosis in children, improving the diagnostic process and scientific research on etiopathology.Materials and methodsWe conducted a clinical report on ADHD diagnosis in children between the ages of 8 and 13, based on the results of (...) the application of different scales to parents of school-age children in Chile. The children were divided into two groups, those with an ADHD diagnosis and those without.ResultsThe results revealed statistically significant differences between groups for scales EDAH y SDQ-Cas, Conners Comprehensive Behavior Scale, Conners Parent Scale and the criteria according to the DSM-V and its dimensions, with the exception of inattention.ConclusionThe findings indicate the importance of appropriate criteria and procedures to establish a diagnosis and implement effective interventions in ADHD.

This paper examines two influential theoretical frameworks, set forth by Russell Barkley (1997) and Thomas Brown (2005), and argues that important headway in understanding attention deficit hyperactivity disorder can be made if we acknowledge the way in which human cognition and action are essentially embodied and enactive. The way in which we actively make sense of the world is structured by our bodily dynamics and our sensorimotor engagement with our surroundings. These bodily dynamics are linked to an individual's (...) concerns and felt needs, so that what she attends to in perception, decision-making, and action is partially constituted by her cares and concerns. What I call ?affective framing? engages the whole living body, and ordinarily contributes to attentional focusing, working memory, goal-formulation, and action-monitoring. However, due to affective framing deficits, subjects with ADHD find it difficult to focus their attention, kindle their motivation, and systematically simplify cognitive procedures according to considerations of relevance, salience, and context. Thus, what is impaired in ADHD is not simply a set of executive brain functions, but rather a range of bodily dynamics through which subjects engage with their world. For this reason, intensive behavioral intervention that engages the whole living body may be the most effective, lasting treatment for ADHD. (shrink)

In this study, we investigated the relationships between judgments of intentionality and moral evaluation in individuals with High Functioning Autism (HFA) or Asperger Syndrome (AS). HFA or AS are neurodevelopmental disorders characterised by severe deficits in communication and social functioning. Impairments in Theory of Mind (ToM), i.e., the ability to attribute mental states to oneself and to others, are thought to be the core features of autism. Of all mental states, the concept of ‘intentional action’ is particularly important. People normally (...) distinguish between actions that are performed intentionally and those that are performed unintentionally and this distinction plays a crucial role in social understanding and moral judgment. Recently, Knobe (Analysis 63: 190–193, 2003a ), (Philosophical Psychology 16: 309–324, 2003b ) showed that people’s moral evaluations might serve as input to the process by which people intuitively arrive at the intentionality judgments. Here, by using two pairs of vignettes, the Knobe’s Harm/Help cases and Murder/Bull’s-eye cases, we showed that, as already observed in typical population, in individuals with HFA/AS judgment of intentional action is informed by the moral appreciation of the action outcome. However, the two groups differed on praise judgments and moral justifications, suggesting that these processes were poorly influenced by the agent’s psychological states. We concluded that, although under certain circumstances, individuals with HFA/AS and people with typical development have similar intuitive judgments of intentionality, over-assignment of praise judgments and the reduced use of folk-psychological concepts in moral judgment likely reflect difficulties using intentionality information for moral reasoning.

Investigations into the neurobiology of moral cognition are often done by examining clinical populations characterized by diminished moral emotions and a proclivity toward immoral behavior. Psychopathy is the most common disorder studied for this purpose. Although cocaine abuse is highly co-morbid with psychopathy and cocaine-dependent individuals exhibit many of the same abnormalities in socio-affective processing as psychopaths, this population has received relatively little attention in moral psychology. To address this issue, the authors used functional magnetic resonance imaging (fMRI) to (...) record hemodynamic activity in 306 incarcerated male adults, stratified into regular cocaine users (n = 87) and a matched sample of non-cocaine users (n = 87), while viewing pictures that did or did not depict immoral actions and determining whether each depicted scenario occurred indoors or outdoors. Consistent with expectations, cocaine users showed abnormal neural activity in several frontostriatial regions during implicit moral picture processing compared to their non-cocaine using peers. This included reduced moral/non-moral picture discrimination in the vACC, vmPFC, lOFC, and left vSTR. Additionally, psychopathy was negatively correlated with activity in an overlapping region of the ACC and right lateralized vSTR. These results suggest that regular cocaine abuse may lead to affective deficits which can impact relatively high-level processes like moral cognition. Moreover, they add to a growing body of research suggesting an important role for the mesocorticolimbic dopamine pathway in socio-affective processing. (shrink)

Introduction: Previous findings that inattention and hyperactive/impulsive symptoms predict later peer problems have been mixed. Utilizing two culturally diverse samples with shared methodologies, we assessed the predictive power of dimensionally measured childhood IA and HI symptoms regarding adolescent peer relationships.Methods: A US-based, clinical sample of 228 girls with and without childhood diagnosed attention-deficit/hyperactivity disorder was assessed and followed 5 years later. A Norwegian, population-based sample of 3,467 children was assessed and followed approximately 4 years later. Both investigations used (...) parent and teacher reports of ADHD symptoms and peer relations. Multivariate regression analyses examined the independent contributions of IA and HI symptoms to later peer problems, adjusting for baseline childhood peer problems. We also examined childhood sex as a potential moderator within the Norwegian sample.Results: Higher levels of childhood HI symptoms, but not IA symptoms, independently predicted adolescent peer problems in the all-female clinical sample. Conversely, higher levels of IA symptoms, but not HI symptoms, independently predicted preadolescent peer problems in the mixed-sex population sample. Results did not differ between informants. Associations between ADHD symptom dimensions and peer problems within the Norwegian sample were not moderated by child sex.Discussion: Differential associations between childhood hyperactive/impulsive and inattention symptoms and adolescent peer problems were found across two diverse samples using a shared methodology. Potential explanations for different findings in the clinical vs. population samples include symptom severity as well as age, sex, and cultural factors. We discuss implications for future research, including the importance of dimensional measures of ADHD-related symptoms and the need for shared methodologies across clinical and normative samples.

How do people detect mental dysfunction? What is the influence of cultural models of dysfunction on this detection process? The detection process as such is not usually researched as it falls between the domains of cross-cultural psychiatry and anthropological ethno-psychiatry . I provide a general model for this “missing link” between behavior and cultural models, grounded in empirical evidence for intuitive psychology. Normal adult minds entertain specific intuitive expectations about mental function and behavior, and by implication they infer that specific (...) kinds of behavior are the result of underlying dysfunction. This suggests that there is a “catalogue” of possible behaviors that trigger that intuition, hence a limited catalogue of possible symptoms that feed into culturally specific folk-understandings of mental disorder. It also suggests that some mental dysfunctions, as they do not clearly violate principles of intuitive psychology, are “invisible” to folk-understandings. This perspective allows us to understand the cultural stability and spread of particular views of madness. It also suggests why certain types of mental disorder are invisible to folk-understandings.

The notion of Attention Deficit Hyperactivity Disorder (ADHD) may have its origins in 1763, when Scottish physician Sir Arthur Crichton observed people who could be easily distracted to a degree approaching the nature of delirium. Since then, the notion of ADHD matured and aroused controversy concerning whether it is a real illness and the motives behind particular methods of its treatments. Despite the controversy, ADHD is well established as a research subject and a frequently diagnosed disorder. Thus, (...) the aim of this paper is not to deal with controversies but rather to show the evolution of methods used for the detection of this disorder. Literature analysis revealed that those methods varied from classical psychological tests/questionnaires to analyses of: eye-motion, micro-motion, brain activity, and behavioral patterns in virtual reality. The main conclusion is that the above methods tend to be heavily computer-aided and that the future belongs to mobile solutions incorporated into complex e-health systems. (shrink)

Sluggish cognitive tempo is a cluster of attentional symptoms characterized by slow information processing and behavior, distractibility, mental confusion, absent-mindedness, and hypoactivity. The present study aimed to compare early and late selective attention in the information processing speed of adults with SCT to those with attention-deficit/hyperactivity disorder and adults without any attentional problems. The participants were screened using Barkley Adult ADHD Rating Scale-IV and divided into the following groups: SCT, ADHD, and controls. All participants completed the irrelevant distractor (...) task measuring early and late selective attention under load condition and distractor condition. The inefficiency index was calculated by subtracting the reaction time of no-distractor condition of correct trials from the reaction time of distractor condition to control the impact of accuracy. Upon analysis, the SCT group showed a lower efficiency compared to the ADHD group under high load, while the ADHD group showed lower efficiency under low load than high load. This meant that the ADHD group had increased efficiency of selective attention with higher load, while the SCT group had low efficiency of selective attention even under high loads. These results suggest that the symptoms of “slow” or “distracted” in SCT could be attributed to the reduced speed and efficiency of selective attention in early information processing and the problem can be pronounced in situations with distractors. The results of the study imply that the attention-deficit-like symptoms shown in those with SCT and ADHD can be distinguished in specific stage of information processing. (shrink)

Attention deficit/hyperactivity disorder (ADHD) has been linked to higher engagement in sexual risk-taking behavior (SRTB). The current study aims to establish the link between ADHD symptoms and SRTB in the general population and to examine whether an exaggerated perceived benefit of the positive outcomes of SRTB explains that link. A scale for measuring the frequency, likelihood, perceived benefit, and perceived risk of SRTB was developed. Young adult sexually active participants who did not have a stable partnership completed the (...) above scale, as well as a scale of ADHD symptoms. Level of ADHD symptoms positively correlated with the frequency and likelihood of SRTB, even when the overall level of sexual behavior was controlled for. ADHD symptoms also correlated with the perceived benefit of SRTB, but not with the perceived risk of SRTB. Mediation analysis confirmed an indirect pathway: ADHD symptoms predicted perceived benefit of SRTB, which in turn predicted increased likelihood to engage in SRTB. These findings suggest a positive link between ADHD symptoms and SRTB in the general population, which is accounted for by an exaggerated perceived benefit of SRTB. (shrink)

Eugen Bleuler introduced the concept of double bookkeeping in schizophrenia to describe the tendency for people who experience delusions to simultaneously be convinced of the delusional content and yet to act as if the delusion(s) was untrue/irrelevant or be unbothered by discrepancies. We open the question of whether there exists a double reality in individuals with addiction and whether double bookkeeping can be applied to addiction. While double bookkeeping has primarily been explored in schizophrenia, this concept may hold promise in (...) elucidating insight deficits in individuals with substance use disorders. We propose two forms of addiction double bookkeeping: 1) Partial compartmentalization: individuals demonstrate some awareness of the deleterious consequences of drug use, but continue to engage in addictive behaviors; and 2) Total compartmentalization: individuals who act as if the negative consequences of addiction do not exist, reflecting a more generalized and deeper lack of awareness into their own actions. We propose that a basic alteration in the individual’s sense of self occurs in addiction double bookkeeping as it does in schizophrenic double bookkeeping. We describe the proposed double reality in addiction from first-person and third-person perspectives, accounting for their differences. Three clinical exemplar cases are presented, and conceptual implications are explored. (shrink)

Autism research has recently witnessed an embodied turn. In response to the cognitivist approaches dominating the field, phenomenological scholars have suggested a reconceptualization of autism as a disorder of embodied intersubjectivity. Part of this interest in autistic embodiment concerns the role of sensory differences, which have recently been added to the diagnostic criteria of autism. While research suggests that sensory differences are implicated in a wide array of autistic social difficulties, it has not yet been explored how sensory and (...) social experience in autism relate on a phenomenological level. Given the importance of the sensory dimension of social encounters in phenomenological analyses of autism, this question must be considered crucial. This article investigates the role played by sensory differences in autistic social experience. Through a phenomenological analysis informed primarily by the philosophy of Maurice Merleau-Ponty with particular emphasis on the relation between intersubjectivity and perception, I argue that sensory differences affect the way other people appear in autistic experience on a pre-reflective level. By drawing on autistic young adults’ experiential descriptions of social encounters, this article identifies three aspects of how sensory differences affect social experiences in autism. First, social encounters manifested as sensorially disturbing, chaotic, and unpredictable events. Second, the embodied expressions of others appeared unfamiliar, threatening, and promoted a sense of detachment from the social world. Third, deliberate practices were employed to actively seek perceptual and social meaning in these disorienting social encounters. This analysis stresses the importance of understanding embodied intersubjectivity through its sensory dimensions. In addition, it indicates an important avenue for future research in exploring the potential role of practice in maintaining an intuitive grip on social meaning. By approaching social encounters as sensory and perceptual events, I emphasize how social difficulties in autism are inherently world-involving phenomena rather than a cognitive deficit reducible to the autistic person.

Prospective follow-up studies have shown that even though some children outgrow the disorder, a childhood diagnosis of attention deficit hyperactivity disorder is clearly a risk factor for a broad range of adverse outcomes, with extremes including drug abuse and juvenile delinquency. This article considers the use of several spectrum concepts and some neuroethical issues. It provides a list of criterion symptoms with a threshold set for the number of symptoms required for categorical diagnoses of disorders. It gives (...) a brief review of some brain imaging and pharmacological treatment studies of ADHD to set the stage for a consideration of brain-specific issues related to neuroethics. Studies using reaction time tasks of cognitive control, response inhibition, and conflict have identified interindividual variance in task performance as one of the most prominent aspects of cognitive deficits related to ADHD.

Some commentaries suggest that the attention-deficit/hyperactivity disorder (ADHD) theory of this condition does not explain enough. Because the theory includes parameters of the delay gradient that vary across individuals and developmental modulation of behavioral outcomes by different environments, it accommodates a wide range of manifestations of ADHD symptoms. Thus, the argument could instead be made that the theory allows too many degrees of freedom. For many purposes, behavior is better defined in terms of function (e.g., consequences) than in (...) terms of structure (e.g., muscle movements), so cognition is treated here as a variety of behavior rather than as a different category of phenomena. The commentaries are discussed in the context of these and other distinctions, including those between association and selection, between operant and respondent behavior, and between fundamental processes and those that are derivative. Other issues include: prosthetic environments, rapidity of developmental change, the concept of inhibition, the form of the delay gradient, and possible directions for experimental research.

Attention deficit hyperactivity disorder is a developmental disorder with an age onset prior to 7 years. Children with ADHD have significantly lower ability to focus and sustain attention and also score higher on impulsivity and hyperactivity. Stimulants, such as methylphenidate, have remained the mainstay of ADHD treatment for decades with evidence supporting their use. However, recent years have seen emergence of newer drugs and drug delivery systems, like osmotic release oral systems and transdermal patches, to mention a (...) few. The use of nonstimulant drugs like atomoxetine and various other drugs, such as a-agonists, and a few antidepressants, being used in an off-label manner, have added to the pharmacotherapy of ADHD. This review discusses current trends in drug therapy of ADHD and highlights the promise pharmacogenomics may hold in the future. (shrink)

While many with schizophrenia experience deficits in metacognition it is unclear whether those deficits are related to other features of illness. To explore this issue, the current study classified participants with schizophrenia as possessing a deficit in both awareness of their own emotions and those of others , aware of their own emotions but unaware of the emotions of others and aware of their own emotions and of other’s emotions . Groups were compared on assessments of neurocognitive function, symptoms, (...) and history of sexual trauma. ANCOVA controlling for education found that the group unaware of their own emotions and those of others demonstrated poorer verbal memory, processing speed, executive function, less emotional discomfort and higher levels of disorganization symptoms relative to the other groups. The group aware of their own emotions but not those of others had a significantly higher report of childhood sexual abuse. (shrink)

Sagvolden, Johansen, Aase, and Russell (Sagvolden et al.) examine attention-deficit/hyperactivity disorder (ADHD) at levels of analysis ranging from neurotransmitters to behavior. At the behavioral level they attribute aspects of ADHD to anomalies of delay-of-reinforcement gradients. With a normal gradient, responses followed after a long delay by a reinforcer may share in the effects of that reinforcer; with a diminished or steepened gradient they may fail to do so. Steepened gradients differentially select rapidly emitted responses (hyperactivity), and they limit (...) the effectiveness with which extended stimuli become conditioned reinforcers, so that observing behavior is less well maintained (attention deficit). Impulsiveness also follows from steepened gradients, which increase the effectiveness of smaller, more immediate consequences relative to larger, more delayed ones. Individuals who vary in the degree to which their delay gradients are steepened will show different balances between hyperactivity and attention deficit. Given the range of ADHD phenomena addressed, it may be unnecessary to appeal to additional behavioral processes such as extinction deficit. Extinction deficit is more likely a derivative of attention deficit, in that failure to attend to stimuli differentially correlated with extinction should slow its progress. The account suggests how relatively small differences in delay gradients early in development might engender behavioral interactions leading to very large differences later on. The steepened gradients presumably originate in properties of neurotransmitter function, but behavioral interventions that use consistently short delays of reinforcement to build higher-order behavioral units as a scaffolding to support complex cognitive and social skills may nonetheless be feasible. Key Words: ADHD; attention deficit; delay gradient; exponential decay; extinction deficit; hyperactivity; impulsiveness; intervention; observing responses; self-control.

Past studies have reported emotional intelligence as a relevant factor in development and maintenance of eating disorders, as well as in increasing self-esteem and reducing anxiety. Similarly, research has showed that anxiety and self-esteem are positively and negatively associated to ED criteria, respectively. However, no prior studies have yet tested the multiple intervening roles of both self-esteem and anxiety as potential mediators of the association between EI and ED symptomatology. The present study aims to bridge these gaps by testing a (...) sequential path model. Specifically, we examine the potential sequential mediation effects of self-esteem-anxiety on the link between EI and ED. A sample composed of 516 Spanish undergraduate students and community adults completed measures of EI, self-esteem, anxiety, and ED symptomatology. The results show that high levels of EI were positively associated with self-esteem and negatively associated with anxiety and ED symptoms. Anxiety was positively associated to ED symptoms, while self-esteem levels were negatively linked to ED symptoms. Moreover, path analyses showed that self-esteem and anxiety fully mediated the relationship between EI and ED symptoms in sequence. These findings suggest that EI plays a key role in reducing symptomatology of ED through increased self-esteem and reduced anxiety symptoms, providing novel evidence regarding psychological mechanisms through which EI contributes to a reduction of ED symptomatology. Implications for assessing and improving these psychological resources in ED preventive programs are discussed. (shrink)

BackgroundAttention deficit hyperactivity disorder is clinically diagnosed; however, quantitative analysis to statistically analyze the symptom severity of children with ADHD via the measurement of head movement is still in progress. Studies focusing on the cues that may influence the attention of children with ADHD in classroom settings, where children spend a considerable amount of time, are relatively scarce. Virtual reality allows real-life simulation of classroom environments and thus provides an opportunity to test a range of theories in a (...) naturalistic and controlled manner. The objective of this study was to investigate the correlation between participants’ head movements and their reports of inattention and hyperactivity, and to investigate how their head movements are affected by different social cues of different sensory modalities.MethodsThirty-seven children and adolescents with and without ADHD were recruited for this study. All participants were assessed for diagnoses, clinical symptoms, and self-reported symptoms. A virtual reality-continuous performance test was conducted under four conditions: control, no-cue, visual cue, and visual/audio cue. A quantitativecomparison of the participants’ head movements was conducted in three dimensions using a head-mounted display in a VR classroom environment. Task-irrelevant head movements were analyzed separately, considering the dimension of movement needed to perform the VR-CPT.ResultsThe magnitude of head movement, especially task-irrelevant head movement, significantly correlated with the current standard of clinical assessment in the ADHD group. Regarding the four conditions, head movement showed changes according to the complexity of social cues in both the ADHD and healthy control groups.ConclusionChildren and adolescents with ADHD showed decreasing task-irrelevant movements in the presence of social stimuli toward the intended orientation. As a proof-of-concept study, this study preliminarily identifies the potential of VR as a tool to understand and investigate the classroom behavior of children with ADHD in a controlled, systematic manner.

Depue & Morrone-Strupinsky's (D&M-S's) model of affiliation meets the criteria advanced for the definition of behavior systems and endophenotypes.

Subthreshold Attention-Deficit/Hyperactivity Disorder is defined as a neurobiological condition with some core inattentive or hyperactive/impulsive symptoms of ADHD which do not meet the full diagnosis clinically. Although it has been well documented that deficits in cognitive control, a high-level cognitive construct closely related to attention, are frequently found among children with ADHD, whether subthreshold ADHD is also associated with similar deficits remains unclear. In this study, we examined the attention functions and the cognitive control capacity in children with (...) ADHD, those with subthreshold ADHD, and typically developing peers. The results showed that the ADHD and subthreshold ADHD groups exhibited similar patterns of the impaired executive function of attention and reduced cognitive control capacity, and no significant difference was found between the two groups. These findings suggest that although children with subthreshold ADHD have not met the full criteria of ADHD, they showed reduced efficiency in cognitive control and attention function, similar to children with ADHD.

Little is known about how children and adolescents conceptualize psychiatric disorders and psychiatric treatment. In the current study, children and adolescents diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) were interviewed about their understanding of ADHD and the medication used to treat their disorder.

Latency-aged children often did not (...) perceive Ritalin as helpful while adolescents recognized some value in taking medication. Some of the adolescents were also able to describe medication side effects. The implications of these findings for patient education are discussed. (shrink)

A substantial body of evidence suggests that autobiographical recollection and simulation of future happenings activate a shared neural network. Many of the neural regions implicated in this network are affected in patients with bipolar disorder , showing altered metabolic functioning and/or structural volume abnormalities. Studies of autobiographical recall in BD reveal overgeneralization, where autobiographical memory comprises primarily factual or repeated information as opposed to details specific in time and in place and definitive of re-experiencing. To date, no study has (...) examined whether these deficits extend to future event simulation. We examined the ability of patients with BD and controls to imagine positive, negative and neutral future events using a modified version of the Autobiographical Interview that allowed for separation of episodic and non-episodic details. Patients were selectively impaired in imagining future positive, negative, and neutral episodic details; simulation of non-episodic details was equivalent across groups. (shrink)

The present study examines the comorbidity between specific learning disorders and attention deficit and hyperactivity disorder by comparing the neuropsychological profiles of children with and without this comorbidity. Ninety-seven schoolchildren from 8 to 14 years old were tested: a clinical sample of 49 children with ADHD, SLD or SLD in comorbidity with ADHD, and 48 typically-developing children matched for age and intelligence. Participants were administered tasks and questionnaires to confirm their initial diagnosis, and a battery of executive function (...) tasks testing inhibition, shifting, and verbal and visuospatial updating. Using one-way ANOVAs, our results showed that all children in the clinical samples exhibited impairments on EF measures when compared with TD children. A more specific pattern only emerged for the updating tasks. Only children with SLD had significant impairment in verbal updating, whereas children with ADHD, and those with SLD in comorbidity with ADHD, had the worst performance in visuospatial updating. The clinical and educational implications of these findings are discussed. (shrink)

Early-Onset Schizophrenia (EOS) and Attention Deficit-Hyperactivity Disorder (ADHD) are early- onset neurodevelopmental disorders associated with cognitive deficits. The current study represents the first attempt to compare these groups on a comprehensive cognitive test battery in a longitudinal design over 25 years in order to enhance our knowledge of particular patterns resulting from the interaction between normal maturational processes and different illness processes of these disorders. In the baseline study, 19 adolescents with schizophrenia were compared to 20 adolescents with (...) ADHD and 30 healthy controls (HC), all between 12 and 18 years of age. After 13 years (T2) and after 25 years (T3) they were re-evaluated with the cognitive test battery. A cognitive Composite Score was used in a linear mixed model. The EOS group had a significant cognitive stagnation or deterioration from T1 to T2 compared to HC. However, the EOS group had the most positive change from T2 to T3, supporting a stable level of cognitive performance over the 25 year span. The ADHD group improved or had similar development as the HC group from T1 to T2. They continued to improve significantly compared to the HC group from T2 to T3. Individuals in the EOS group performed more impaired on the cognitive composite score compared to the HC group and the ADHD group at all three time points. Results might indicate a neurodevelopmental pathway of EOS with subnormal cognitive development specific in adolescence. In comparison, the ADHD group had a more consistent cognitive maturation supporting a maturational delay hypothesis of ADHD. (shrink)

Aphantasia is a condition characterised by a deficit of mental imagery. Since several psychopathologies are partially maintained by mental imagery, it may be illuminating to consider the condition against the background of psychological disorder. After outlining current findings and hypotheses regarding aphantasia and psychopathology, this paper suggests that some support for defining aphantasia as a lack of voluntary imagery may be found here. The paper then outlines potentially fruitful directions for future research into aphantasia in general and its (...) relation to psychopathology in particular, including rethinking use of the SUIS to measure involuntary imagery, whether aphantasia offers protection against addiction, and whether hyperphantasia is a potential risk factor for maladaptive daydreaming, among others.

Fear is often seen as pathological, to be eliminated by expensive emotion-damping pharmaceuticals that have drastic side effects. Such therapies have indiscernible long-term success since they ignore why we have brains. This paper offers a new fundamental theory based on recognising that mental illness is bad decisionmaking—bad risk processing of external stimuli. Whiffs of danger—small risks —generate little fears and hopes of whether an act will have a nice or nasty surprise. From enough whiffs of danger with rapid reliable feedback (...) on whether the surprise is nice or nasty, and in adequate variety children learn the difference between luck and sensible choice, and adults maintain adequate decisionmaking—the author’s ‘whiffs of danger’ theory. Lack of whiffs constitutes risk starvation and can arise from under-challenge or over-challenge. Boys’ ADHD springs from under-challenge in physical risks—the digital seduction—and over-challenge in mental, psychological, social risks—by faster maturing schoolgirls as teachers quit traditional boy favouritism. Boys’ IQ/maturity over-challenge could be cut by: appropriate pre-school care; single sex schools or in co-ed schools boys’ school entry postponed so one year older than their female classmates; and boys praised for expressions of fears, hopes, not for emotion-damped macho utterances. Under-challenge underlies some panic attacks and epileptic fits, and a high proportion of depressions and dementias. Like schoolboys’ physical under-challenge, these under-challenges are reducible by compensating societal changes. (shrink)

There is ample evidence from literature and clinical practice indicating mathematical difficulties in individuals with ADHD, even when there is no concomitant diagnosis of developmental dyscalculia. What factors underlie these difficulties is still an open question. Research on dyscalculia and neurotypical development suggests visual perception of numerosity (the number sense) as a building block for math learning. Participants with lower numerosity estimation thresholds (higher precision) are often those with higher math capabilities. Strangely, the role of numerosity perception in math skills (...) in ADHD has been neglected, leaving open the question whether math difficulties in ADHD also originate from a deficitary visual number sense. In the current study we psychophysically measured numerosity thresholds and accuracy in a sample of children/adolescents with ADHD, but not concomitant dyscalculia (N = 20, 8–16 years). Math abilities were also measured by tasks indexing different mathematical competences. Numerosity performance and math scores were then compared to those obtained from an age-matched control group (N = 20). Bayesian statistics indicated no difference between ADHD and controls on numerosity perception, despite many of the symbolic math tasks being impaired in participants with ADHD. Moreover, the math deficits showed by the group with ADHD remained substantial even when numerosity thresholds were statistically regressed out. Overall, these results indicate that math difficulties in ADHD are unlikely to originate from an impaired visual number sense. (shrink)

The neural networks that constitute corticostriatothalamocortical circuits between prefrontal cortex and subcortical structure provide a heuristic framework for bridging gaps between neurocircuitry and executive dysfunction in attention deficit hyperactivity disorder (ADHD). “Cool” and “Hot” executive functional theory and the models of dual pathway are supposed to be applied within the neuropsychology of ADHD. The theoretical model elaborated response inhibition and delayed gratification in ADHD. We aimed to review and summarize the literature about the circuits on ADHD and ADHD-related (...) comorbidities, as well as the effects of neurocircuitry on the executive dysfunction in ADHD.

Attention-deficit hyperactivity disorder is one of the most common neurodevelopmental disorders in children and adolescents. People who have this disorder are characterized by presenting difficulties in the processes of sustained attention, being very active, and having poor control of their impulses. Despite the high prevalence of this disorder and the existence of various tests used for its diagnosis, few data are available regarding the usefulness and diagnostic validity of these tools. Given the difficulties that these subjects (...) present in executive functions, the aim of this study was to evaluate whether the Neuropsychological Assessment of Executive Functions battery for Children allows to establish specific profiles of executive performance for people with attention-deficit hyperactivity disorder. The sample was made up of 197 participants of both sexes, aged between 6 and 12 years age. A nonexperimental design was followed, using a comparative descriptive study method. The results indicated that the scales of phonological fluency, color path, rings, and interference are the most associated with the diagnosis of ADHD, providing data on inhibition, mental flexibility, sustained and selective attention, planning, verbal fluency, and working memory, among others. The practical implication of these results is in line with providing support in the clinical diagnosis that is carried out in children’s mental health units. In addition, the ENFEN tool can be valued as a suitable psychometric instrument in the psychoeducational field, helping professionals in a school environment to be more aware of the areas of cognitive development in which a student diagnosed with ADHD will have more difficulties and, in doing so, providing more adjusted and effective psychopedagogical measures when it comes to supporting students in their adaptation to the school environment.

Attention deficit hyperactivity disorder affects children, adolescents, and adults. Research suggests ADHD has a heritable component. The present article presents and assesses several genetic animal models of ADHD. The paper reviews the literature involving the following genetic animal models of ADHD: the spontaneously hypertensive rat ; the Wistar–Kyoto hyperactive rat; the coloboma mouse; the fast kindling rat; the acallosal mouse; the whirler mouse; and the genetically hypertensive rat. Research investigating animal models of ADHD has concentrated on hyperactivity, but (...) impulsiveness, learning, and attention are also being examined. The use of animal models allows for the control of possibly confounding variables and has proven very useful in the screening of new therapies. These models have not been shown to be the equivalent of the human disorder, and no model encompasses all of the symptoms of the human disorder, but they are useful nevertheless. (shrink)

ADHD is a psychiatric disorder characterised by persistent and developmentally inappropriate levels of inattention, impulsivity and hyperactivity. It is known that children with ADHD tend to produce incoherent discourses, e.g. by narrating events out of sequence. Here the aetiology of ADHD becomes of interest. One prominent theory is that ADHD is an executive function disorder, showing deficiencies of planning. Given the close link between planning, verb tense and discourse coherence postulated in van Lambalgen and Hamm (The proper treatment (...) of events, 2004), we predicted specific deviations in the verb tenses produced by children with ADHD. Here we report on an experiment corroborating these predictions. (shrink)

Critics of attention-deficit/hyperactivity disorder (ADHD) have repeatedly argued that there is no proof for the condition being symptomatic of an organic brain disease and that the current "ADHD epidemic" is an expression of medicalization. To this, the supporters of ADHD can retort that the condition is only defined as a mental disorder and not a physical disease. As such, ADHD needs only be a harmful mental dysfunction, which, like other genuine disorders, can have a complex and obscure (...) etiology. This article argues that such a line of argument fails to save ADHD as a valid diagnostic category. Given the general diagnostic logic of the DSM-IV and how ADHD has been defined in terms of everyday (male) child behaviors, there are compelling grounds to disbelieve that ADHD can be a true medical syndrome united by some type of harmful dysfunction. Indeed, strong logical and empirical reasons will be adduced to show that people may qualify for ADHD diagnosis without suffering from any type of underlying pathology. (shrink)

Eye movements during false-belief tasks can reveal an individual's capacity to implicitly monitor others' mental states (theory of mind - ToM). It has been suggested, based on the results of a single-trial-experiment, that this ability is impaired in those with a high-functioning autism spectrum disorder (ASD), despite neurotypical-like performance on explicit ToM measures. However, given there are known attention differences and visual hypersensitivities in ASD it is important to establish whether such impairments are evident over time. In addition, investigating (...) implicit ToM using a repeated trial approach allows an assessment of whether learning processes can reduce the ASD impairment in this ability, as is the case with explicit ToM. Here we investigated the temporal profile of implicit ToM in individuals with ASD and a control group. Despite similar performance on explicit ToM measures, ASD-diagnosed individuals showed no evidence of implicit false-belief tracking even over a one-hour period and many trials, whereas control participants did. These findings demonstrate that the systems involved in implicit and explicit ToM are distinct and hint that impaired implicit false-belief tracking may play an important role in ASD. Further, they indicate that learning processes do not alleviate this impairment across the presentation of multiple trials. (shrink)

Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. Inattentiveness, overactivity, and impulsiveness are presently regarded as the main clinical symptoms. The dynamic developmental behavioral theory is based on the hypothesis that altered dopaminergic function plays a pivotal role by failing to modulate nondopaminergic (primarily glutamate and GABA) signal transmission appropriately. A hypofunctioning mesolimbic dopamine branch produces altered reinforcement of behavior and deficient extinction of previously reinforced behavior. This gives (...) rise to delay aversion, development of hyperactivity in novel situations, impulsiveness, deficient sustained attention, increased behavioral variability, and failure to “inhibit” responses (“disinhibition”). A hypofunctioning mesocortical dopamine branch will cause attention response deficiencies (deficient orienting responses, impaired saccadic eye movements, and poorer attention responses toward a target) and poor behavioral planning (poor executive functions). A hypofunctioning nigrostriatal dopamine branch will cause impaired modulation of motor functions and deficient nondeclarative habit learning and memory. These impairments will give rise to apparent developmental delay, clumsiness, neurological “soft signs,” and a “failure to inhibit” responses when quick reactions are required. Hypofunctioning dopamine branches represent the main individual predispositions in the present theory. The theory predicts that behavior and symptoms in ADHD result from the interplay between individual predispositions and the surroundings. The exact ADHD symptoms at a particular time in life will vary and be influenced by factors having positive or negative effects on symptom development. Altered or deficient learning and motor functions will produce special needs for optimal parenting and societal styles. Medication will to some degree normalize the underlying dopamine dysfunction and reduce the special needs of these children. The theory describes how individual predispositions interact with these conditions to produce behavioral, emotional, and cognitive effects that can turn into relatively stable behavioral patterns.
