The existence or questionability of “repressed memories” can be discussed as being a matter of definition. It seems, however, far-fetched to consider all “lost” memories as caused by encoding problems, brain damage, forgetfulness, failure to disclose events, and so on. We argue that dissociative amnesia (DA) (or “psychogenic amnesia,” or “functional amnesia,” or, as we favor to call it, “mnestic block syndrome”) is caused by psychic alterations, but ultimately they can be traced to changes in the physiology (...) of the brain, as we are of the opinion that all memory processes—positive or negative—alter brain functions, sometimes more permanently, sometimes transiently. We have proven this idea using functional imaging techniques, in particular fluoro-deoxy-d-glucose positron emission tomography. Having investigated dozens of patients with severe and long-lasting DA conditions, we believe it to be disrespectful to many (but not to all) of the affected patients to question their disease condition, which can be proven to be not caused by feigning, malingering, or direct brain damage.

Complex regional pain syndromes (reflex sympathetic dystrophy, causalgia) are often characterized by pain and autonomic and motor abnormalities. Pathophysiological mechanisms are in the central and peripheral nervous system. Differences in skin temperature and may be used as diagnostic criteria. Sympathetic blocks relieve pain and other symptoms in a subgroup of patients (sympathetically maintained pain, SMP).[blumberg et al.].

In lieu of an abstract, here is a brief excerpt of the content:Subjective Experiences of Tourette SyndromeBeyond the Premonitory UrgeThe authors report no conflicts of interest.There is an evolving recognition in healthcare that the patient's subjective experience needs to be privileged both in understanding clinical phenomena and also ensuring the salience of outcomes used to evaluate the impact of treatment interventions. This is reflected in the expansion of patient-reported outcome measures to capture a person's perception of their own health, and (...) the increasing requirement of involving people with lived experience in the co-design of research studies (National Health and Medical Research Council, 2016) and care improvement initiatives. In mental health it has been long understood that observable behavioral phenomena can only partially inform clinical understanding of the experience of the patient living with the condition. However, capturing the patient's subjective experience faithfully remains a challenge.Tourette syndrome (TS) is a complex condition in which there are clearly observable behavioral phenomena (vocal and motor tics, compulsive and socially inappropriate behaviors), but also a broad and varied range of subjective phenomena reported by different individuals. These may include sensory phenomena such as the premonitory sensory urge preceding a tic, compulsions to touch things a certain number of times or do something repeatedly until it feels "just right," or bothersome intrusive thoughts or images. To further complicate the picture most patients with TS have one or more co-occurring conditions such as attention deficit hyperactivity disorder, obsessive-compulsive disorder, and anxiety, which may actually cause a greater burden of dysfunction and distress than the Tourette symptoms.In their paper, Curtis-Wendlandt et al. (2024) challenge the dependence of current psychiatric diagnostic criteria (e.g., the Diagnostic and Statistical Manual of Mental Disorders, 5th edition) on observable tics, and propose a broader and more dimensional approach to nosology which incorporates sensory, cognitive and affective phenomena. [End Page 47] Data from interviews they conducted identified that premonitory phenomena and urge experiences in tic disorders are more complex and diverse than what is currently reflected in the literature and clinical scales. They also interviewed participants who reported "no urges" or "no premonitory sensations." They commented that the literature generally treats reports of urge absences at face value, and does not address the likelihood that such reports may be ambiguous or problematic. Overall, they concluded that their research suggests that premonitory urges in TS are a complex and diverse phenomenon that requires further study. This reflects with our clinical experience in working with TS patients. Although a large proportion of older patients describe sensory-based premonitory urges, descriptions are not homogenous, with many describing other experiences preceding their tics.When evaluating a patient's response to an intervention (either behavioral or pharmacological) clinicians incorporate a range of information. This includes the severity of their tics (number, type, frequency, intensity, and associated impairment), as well as their mood, participation and performance in study, work, and social activities, and overall quality of life. Standard clinical practice would not typically include assessment of some of the subjective experiences which precede tics. If it was accepted that these subjective phenomena are indeed salient to the patient's well-being, then a challenge would be how to consistently and reliably capture these feelings to operationalize a comprehensive patient-centered assessment.The primary evidence-based treatment for tic disorders, comprehensive behavioral intervention for tics (CBIT), involves training to increase the awareness of premonitory urges (Woods et al., 2008). Furthermore, successful 'blocking' of tics during the course of CBIT requires the patient to be aware of premonitory urges. Clinicians having a better understanding of the complexity and diversity of experiences which precede tics, as well as using open-ended questioning styles, may assist with improving CBIT outcomes.

People with Down syndrome often exhibit deficiencies in wayfinding activities, particularly route learning (e.g., Courbois et al., 2013 ; Davis et al., 2014 ; Farran et al., 2015 ). Evidence concerning more sophisticated survey learning has been sparse. In the research reported here, two experiments are reported that evaluated survey learning of youth with DS and typically developing children (TD) matched on mental age. In Experiment 1, participants learned two overlapping routes consisting of three turns each through a virtual (...) environment depicting 9 square city blocks. Following acquisition, they were tested on multiple measures of survey knowledge: finding a shortcut, identifying the direction of landmarks not currently visible from their location in the environment, and recognizing a bird’s-eye representation of the overall environment. Under these conditions, which should provide relatively optimal opportunities for survey learning, the participants with DS performed comparably to TD participants matched on non-verbal ability on all of our measures of survey learning. Hence, we concluded that people with DS can acquire some survey knowledge when tasked with learning a small environment and given the opportunity to do so. In Experiment 2, the experimenter navigated participants through a large, relatively complex, virtual environment along a circuitous path, beginning and ending at a target landmark. Then, the participants were placed at a pre-specified location in the environment that they had viewed previously and instructed to navigate to the same target (a door) using the shortest possible path from their current location. They completed the task three times: once after being shown the environment one time, once after three exposures, and once after five exposures. Results indicated that the participants with DS exhibited significantly less skill at identifying the shortcut than did the TD participants, with differences emerging as the number of exposures increased. Participants with DS were also less able to recall landmarks at the end of the experiment. Overall, however, the performance of both groups was relatively poor in both experiments – with the performance of participants with DS being worse as conditions became less optimal. These results were discussed in terms of underlying mechanisms that may account for variations in survey learning as environmental complexity increases. (shrink)

Block () highlights two experimental studies of neglect patients which, he contends, provide ‘dramatic evidence’ for unconscious seeing. In Block's hands this is the highly non-trivial thesis that seeing of the same fundamental kind as ordinary conscious seeing can occur outside of phenomenal consciousness. Block's case for it provides an excellent opportunity to consider a large body of research on clinical syndromes widely held to evidence unconscious perception. I begin by considering in detail the two studies of (...) neglect to which Block appeals. I show why their interpretation as evidence of unconscious seeing faces a series of local difficulties. I then explain how, even bracketing these issues, a long-standing but overlooked problem concerning our criterion for consciousness problematizes the appeal to both studies. I explain why this problem is especially pressing for Block given his view that phenomenal consciousness overflows access consciousness. I further show that it is epidemic—not only affecting all report-based studies of unconscious seeing in neglect, but also analogous studies of the condition most often alleged to show unconscious seeing, namely blindsight.

Recent evidence from studies on DNA repair systems that are implicated in accelerated aging syndromes, have revealed a mechanism through which low levels of persistent damage might exert beneficial effects for both cancer prevention and longevity assurance. Beneficial effects of adaptive responses to low doses of insults that in higher concentrations show adverse effects are generally referred to as hormesis. There are numerous examples of hormetic effects ranging from mild stresses of irradiation to heat stress, hypergravity, pro‐oxidants, or food restriction. (...) Although the notion of hormesis is supported by many observations in various organisms, at least two major caveats have thus far prevented the application of hormesis for disease prevention in humans. First, the very nature of hormesis using toxins as a treatment regimen harbors the inherent danger of detrimental consequences. Second, the molecular mechanisms through which insults might exert beneficial effects have thus far remained elusive. Here, I discuss a mechanistic basis for hormesis and its implications for cancer prevention and healthy aging. (shrink)

It is argued that Block's thought experiment on superblindsight and “the Inverse Anton's syndrome” are not cases of A-consciousness without P-consciousness. “Weak dispositional states” should be excluded from the set of A-conscious states, and a subject's being reflectively conscious of a P-conscious state is suggested as a better candidate for A-consciousness. It is further pointed out that dreams, according to Block's own criterion but contrary to what he claims, are A-unconscious and it is argued that Block (...) should not accept the idea that high-information representational content is an empirically sufficient condition of phenomenality in human beings.

The target article discusses various aspects of the relationship between the sympathetic system and pain. To this end, the patients under study are divided into three groups. In the first group, called (RSD), the syndrome can be characterized by a triad of autonomic, motor, and sensory symptoms, which occur in a distally generalized distribution. The pain is typically felt deeply and diffusely, has an orthostatic component, and is suppressed by the ischemia test. Under those circumstances, the pain is likely (...) to respond to sympatholytic interventions. In a second group, called (SMP) syndrome, the principal symptoms are spontaneous pain, which is felt superficially and has no orthostatic component, and allodynia. These symptoms, typically confined to the zone of a lesioned nerve, may also be relieved by sympathetic blocks. Since the characteristics of the pain differ between RSD and SMP, the underlying kind of sympathetic–sensory coupling may also vary between these cases. A very small third group of patients exhibits symptoms of both RSD and SMP. The dependence or independence of pain on sympathetic function reported in most published studies seems to be questionable because the degree of technical success of the block remains uncertain. Therefore, pain should not be reported as sympathetic function independent until the criteria for a complete sympathetic block have been established and satisfied. (shrink)

As neurophysiological investigations of sleep cycle control have provided an increasingly detailed picture of events at the cellular level, the concept that the sleep cycle is generated by the interaction of multiple, anatomically distributed sets of neurons has gradually replaced the hypothesis that sleep is generated by a single, highly localized neuronal oscillator.Cell groups that discharge during rapid-eye-movement (REM) sleep (REM-on) and neurons that slow or cease firing during REM sleep (REM-off) have long been thought to comprise at least two (...) neurochemically distinct populations. The fact that putatively cholinoceptive and/or cholinergic (REM-on) and putatively aminergic (REM-off) cell populations discharge reciprocally over the sleep cycle suggests a causal interdependence.In some brain stem areas these cell groups are not anatomically segregated and may instead be neurochemically mixed (interpenetrated). This finding raises important theoretical and practical issues not anticipated in the original reciprocal-interaction model. The electrophysiological evidence concerning the REM-on and REM-off cell groups suggests a gradient of sleep-dependent membrane excitability changes that may be a function of the connectivity strength within an anatomically distributed neuronal network. The connectivity strength may be influenced by the degree of neurochemical interpenetration between the REM-on and REM-offcells. Recognition of these complexities forces us to revise the reciprocal-interaction model and to seek new methods to test its tenets.Cholinergic microinjection experiments indicate that some populations of REM-on cells can execute specific portions of the REM sleep syndrome or block the generation of REM sleep. This observation suggests that the order of activation within the anatomically distributed generator populations may be critical in determining behavioral outcome. Support for the cholinergic tenets of the reciprocal-interaction model has been reinforced by observations from sleep-disorders medicine.Specific predictions of the reciprocal-interaction model and suggestions for testing these predictions are enumerated for future experimental programs that aim to understand the cellular and molecular basis of the mammalian sleep cycle.

In lieu of an abstract, here is a brief excerpt of the content:Circumcision:Ordinary and Universal in My CommunityAllan J. JacobsMy1 circumcision experiences are remarkable mostly for their ordinariness. My wife Danaë gave birth to our son Perseus2 while I was a resident in obstetrics and gynecology in a city where we had no family. Perseus was circumcised in a Jewish brit milah3 ceremony on the eighth day of his life, as were my wife's and my male ancestors back into ancient (...) times. We were relieved because Perseus had just recovered from a potentially serious condition. After a difficult forceps delivery, his blood bilirubin rose almost to the point where he might have developed the dreaded kernicterus syndrome. Kernicterus can cause permanent severe motor, intellectual and visual impairment. It was unclear whether he would be discharged from the hospital in time. He had to spend a week in restraints under a bright light whose frequency degraded bilirubin. Happily, he came home the day before the scheduled brit.Our four parents attended the brit. Danaë's father was the sandek,4 being granted the honor of holding our son on his lap during the circumcision ceremony. The mohel, or circumciser, was the local Conservative rabbi. We were mildly anxious because he didn't do many circumcisions in this city with few Jews. Perseus cried briefly after he was circumcised. The circumcision undoubtedly was far less stressful than treatment of elevated bilirubin. The circumcision certainly was less painful than the prodding and sticks for the many blood tests he had to undergo in the hospital, not to mention the pain of his difficult forceps delivery. Perseus did not seem to have much discomfort in his penis afterward, and had no circumcision complications.After the brit, our parents and my resident colleagues ate refreshments and chatted for an hour or so. A brit milah is a happy occasion, but not an elaborate one. It marks the end of the joy, anxiety, and excitement of the child's birth and its aftermath and is followed by the less exalted rhythm of feedings, diaper changes, and sleep deprivation.At the brit, our boys are assigned Hebrew names and confirmed in the Biblical covenant between God and the Hebrew people established between God and Abraham, and reaffirmed between God and Moses. Regardless of the historical truth of the formation of the covenant, it is accepted as a myth tantamount to [End Page 71] truth. In other words, regardless of its literal truth, such a myth is to be regarded as true because it concretizes God's demands or a moral truth. The covenant is real for me whether or not there was a historical Abraham. As with other religious commitments, the obligation to circumcise our sons is unprovable, but binding. On this basis, Perseus's ancestors on both sides were circumcised in brit milah ceremonies for many centuries into the past.My two grandsons were circumcised as well. Achilles was circumcised among friends and relatives. The mohel was an experienced obstetrician who was certified to officiate at a brit milah following the practices of Conservative Judaism. He administered adequate analgesia with topical local anesthetic cream followed by an injected regional block. Achilles slept through his circumcision, suffered no complications, and had little discomfort afterward. My other grandson had a circumcision performed as an infant outside the context of Judaism and is not being raised as a Jew.The two brit milah in my family were beautiful, dignified ceremonies, welcoming the infants into the Jewish fold, and bestowing their Hebrew names.5 Some of my relatives, including Perseus's son, had circumcisions performed in a medical setting without a ceremony. None of the many boys in my family had obvious short- or long-term problems with their circumcisions. My social circle has many Reform and Conservative Jews. I have never heard any Jewish man in my circle of acquaintances complain about his circumcision. Circumcision is a given. Problems are rare, and an exposed glans is the norm. Our men typically enjoy sex and have no difficulty in fathering children. Circumcision is part of the comforting cocoon of custom and tribe that helps to protect us as a group. It also reinforces Jewish endogamy... (shrink)

The problem this article is concerned with is the failure ofmany large organizations in formerly socialist countries and inpublic sectors of market economies to make effective, peaceful,and ethical transformation from command to market responsiveorganization and privatization. There are at least threeimportant behavioral causes of this problem. First, organizationtransformation is blocked because the organization tries tochange "all at once" before the organization has learned how toact successfully in a new for the organization environment as amarket responsive instead of a command organization (...) (Churchman,1971; Quinn, 1980; Nystrom and Starbuck, 1984; Mintzberg andWaters, 1985; Mintzberg, 1994; Goldman, 1994). Second,organization transformation is blocked because "all at oncechange" stimulates so much fear and political opposition thatchange is politically not possible (Argyris and Schon, 1974;Argyris, 1990; Goldman, 1994; Sachs, 1992). Third, organizationtransformation is blocked because the "guardian" ethics syndromeof command organization is less appropriate for market responsiveorganization than a "commercial" ethics syndrome (Jacobs, 1992;Harris, 1995). Gradual intrapreneurship (Burgelman, 1983; Nielsenet al., 1985) can serve as a peaceful and ethical transitionstrategy. Intrapreneurship can help bridge some of thecontradictions between "commercial" vs. "guardian" ethicssyndromes (Jacobs, 1992; Nielsen, 1996). (shrink)

The first serious scientific studies on the brain date back to the 1800s. Two events led the studies on the brain. The first incident is an accident involving Phineas Gage, a railway worker. The two-meter-long piece of iron that entered Gage's left eye and broke up the anterior frontal lobe of the brain prompted scientists to rethink the brain. Having lived a moral life before the accident, Gage became immoral and evil after the accident. This incident revealed that the brain (...) has a relationship with evil. -/- The second event affecting the brain studies is the split brain syndrome that occurs when the corpuscallosum of patients with epilepsy is cut. The separation of the right and left brains has caused some problems in individuals. For example, while the left brain smokes, the right brain tries to block it, while the left brain drives a car, the right brain wants to get out of the way. The right brain behaves in a childish and impulsive manner and cannot be controlled. -/- After all, any disease, accident or surgery that occurs in the brain can negatively affect people's behavior and make them worse. Then, the neuroscientific origins of the evil issue should be investigated and evaluated according to neuro-philosophy. In this paper, the limits of human freedom, scientific determinism and human responsibility will be set forth. Thus, in the issue of evil, it will be shown that the biological (and psychological) structure of the human being, together with external factors such as the environment, society, education, and culture, and the changes that occur in it, are determined in the human will and choosing evil.

Certain patients with a possible contribution of the sympathetic system to pain may not fit the definition of complex regional pain syndromes (CRPS), which raises the question of terminology for those patients. To further clarify the relationship between the sympathetic system and pain, apart from the need for placebo studies, there remains an urgent need for a satisfactory definition of the criteria for a complete sympathetic block. It also remains uncertain whether a change in the discharge pattern of sympathetic (...) fibres underlies the changes in sympathetic organ function, often found in patients with CRPS. (shrink)

A practical, refreshingly optimistic guide that uses centuries-old wisdom to help us better cope with the stresses of modern living. Some people bounce back in response to setbacks; others break. We often think that these responses are hardwired, but fortunately this is not the case. Stoicism offers us an alternative approach. Plumbing the wisdom of one of the most popular and successful schools of thought from ancient Rome, philosopher William B. Irvine teaches us to turn any challenge on its head. (...) The Stoic Challenge, then, is the ultimate guide to improving your quality of life through tactics developed by ancient Stoics, from Marcus Aurelius and Seneca to Epictetus. This book uniquely combines ancient Stoic insights with techniques discovered by contemporary psychological research, such as anchoring and framing. The result is a surprisingly simple strategy for dealing with life’s unpleasant and unexpected challenges—from minor setbacks like being caught in a traffic jam or having a flight cancelled to major setbacks like those experienced by physicist Stephen Hawking, who slowly lost the ability to move, and writer Jean-Dominique Bauby, who suffered from locked-in syndrome. The Stoics discovered that thinking of challenges as tests of character can dramatically alter our emotional response to them. Irvine’s updated “Stoic test strategy” teaches us how to transform life’s stumbling blocks into opportunities for becoming calmer, tougher, and more resilient. Not only can we overcome everyday obstacles—we can benefit from them, too. (shrink)

Referring to Professor (...) Jerzy Kmita’s theory of culture, the way of thinking adopted in the publication is identified based on values and knowledge that are shaped within the frame of the intellectual partnership, as well as being respected and applied in practice. The way of thinking – reproduced on the basis of the actual actions – can significantly deviate from that which is stated, accepted, or articulated as desired. Mental barriers determine this. Their identification is based – in the proposed concept – on an analysis of syndromes. The more significant the share of mental barrier syndromes is for the organization’s way of thinking, the greater the difference between the actual and desired state of affairs. The competences achieved through academic humanistic education are necessary in the blocking of mental barrier syndromes. From the perspective of the needs of modern organizations, skills in information processes appear to be very useful. The author attributes a special role to the quantification of knowledge. Reflections on the mental barrier syndromes are included by the author in The Theory of a thinking organization analogously to The Theory of a learning organization or The Theory of constraints. At the same time he highlights its interdisciplinary character and intellectual pedigree, pointing at the methodological school of Poznań, especially the thoughts of Professor Jerzy Kmita. (shrink)

This article concerns the interplay between two issues that involve both philosophy and neuroscience: whether the content of phenomenal consciousness is 'rich' or 'sparse', whether phenomenal consciousness goes beyond cognitive access, and how it would be possible for there to be evidence one way or the other.

There are two concepts of consciousness that are easy to confuse with one another, access-consciousness and phenomenal consciousness. However, just as the concepts of water and H 2 O are different concepts of the same thing, so the two concepts of consciousness may come to the same thing in the brain. The focus of this paper is on the problems that arise when these two concepts of consciousness are conflated. I will argue that John Searle's reasoning about the function of (...) consciousness goes wrong because he conflates the two senses. And Francis Crick and Christof Koch fall afoul of the ambiguity in arguing that visual area V1 is not part of the neural correlate of consciousness. Crick and Koch's work raises issues that suggest that these two concepts of consciousness may have different neural correlates – despite Crick and Koch's implicit rejection of this idea. (shrink)

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

This book argues that there is a joint in nature between seeing and thinking, perception, and cognition. Perception is constitutively iconic, nonconceptual, and nonpropositional, whereas cognition does not have these properties constitutively. The book does not appeal to “intuitions,” as is common in philosophy, but to empirical evidence, including experiments in neuroscience and psychology. The book argues that cognition affects perception, i.e., that perception is cognitively penetrable, but that this does not impugn the joint in nature. A key part of (...) the argument is that we perceive not only low-level properties like colors, shapes, and textures but also high-level properties such as faces and causation. Along the way, the book explains the difference between perception and perceptual memory, the differences between format and content, and whether perception is probabilistic despite our lack of awareness of probabilistic properties. The book argues for perceptual categories that are not concepts, that perception need not be singular, that perceptual attribution and perceptual discrimination are equally fundamental, and that basic features of the mind known as “core cognition” are not a third category in between perception and cognition. The chapter on consciousness leverages these results to argue against some of the most widely accepted theories of consciousness. Although only one chapter is about consciousness, much of the rest of the book repurposes work on consciousness to isolate the scientific basis of perception. (shrink)

The functionalist view of the nature of the mind is now widely accepted. Like behaviorism and physicalism, functionalism seeks to answer the question "What are mental states?" I shall be concerned with identity thesis formulations of functionalism. They say, for example, that pain is a functional state, just as identity thesis formulations of physicalism say that pain is a physical state.

Much of recent philosophy of perception is oriented towards accounting for the phenomenal character of perception—what it is like to perceive—in a non-mentalistic way—that is, without appealing to mental objects or mental qualities. In opposition to such views, I claim that the phenomenal character of perception of a red round object cannot be explained by or reduced to direct awareness of the object, its redness and roundness—or representation of such objects and qualities. Qualities of perception that are not captured by (...) what one is directly aware of or by representational content are instances of what Gilbert Harman has called “mental paint” (Block, 1990; Harman, 1990). The claim of this paper is that empirical facts about attention point in the direction of mental paint. The argument starts with the claim (later modified) that when one moves one's attention around a scene while keeping one's eyes fixed, the phenomenology of perception can change in ways that do not reflect which qualities of objects one is directly aware of or the way the world is represented to be. These changes in the phenomenology of perception cannot be accounted for in terms of awareness of or representation of the focus of attention because they manifest themselves in experience as differences in apparent contrast, apparent color saturation, apparent size, apparent speed, apparent time of occurrence and other appearances. There is a way of coping with these phenomena in terms of vague contents, but vague contents cannot save direct realism or representationism because the kind of vagueness required clashes wth the phenomenology itself.

Wysocki (2024) is a critique of Block (2022). The present paper is a response to the former. We are in effect debating the best reaction to Nozick (1977) which criticized Austrian economics on the ground that it makes two claims that are incompatible with one another. On the one hand, the praxeological school is noted for its aversion to the concept of indifference. On the other hand, the Austrian school also accepts supply and demand curves, and diminishing marginal utility. (...) These three concepts imply homogeneous elements that comprise them. But if they are truly homogeneous, people ought to be indifferent between the different elements of them. Hence, the tension, not to say logical contradiction, in this perspective. Block (1980) was an attempt to respond to Nozick (1977). Hoppe (2005a,b; 2009) and Wysocki (2016; 2017; 2021; 2024) who supports Hoppe, maintain that Block’s refutation of Nozick (1977) was not efficacious at all, at worst, or at best, certainly not fully successful. Specifically, Wysocki maintains that there is a bifurcation between choosing and preferring; for example, no one is even aware of which foot goes first when entering a restaurant, and, yet, one has to make a choice about it. He avers that it is entirely possible to prefer to save either son, equally, while actually picking one, and not the other. (shrink)

How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We can see the problem in stark form if we ask how we could tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: find the neural natural kinds that are the basis of phenomenal consciousness in clear cases when subjects are completely confident and we have no reason to doubt their (...) authority, and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is ‘Yes’, then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is ‘Yes’? The suggested methodology requires an answer to the question it was supposed to answer! The paper argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. The paper argues that we can find a neural realizer of this overflow if assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified by the explanations it allows.

The explanatory gap . Consciousness is a mystery. No one has ever given an account, even a highly speculative, hypothetical, and incomplete account of how a physical thing could have phenomenal states. Suppose that consciousness is identical to a property of the brain, say activity in the pyramidal cells of layer 5 of the cortex involving reverberatory circuits from cortical layer 6 to the thalamus and back to layers 4 and 6,as Crick and Koch have suggested for visual consciousness. .) (...) Still, that identity itself calls out for explanation! Proponents of an explanatory gap disagree about whether the gap is permanent. Some say that we are like the scientifically naive person who is told that matter = energy, but does not have the concepts required to make sense of the idea. If we can acquire these concepts, the gap is closable. Others say the gap is uncloseable because of our cognitive limitations. Still others say that the gap is a consequence of the fundamental nature of consciousness. (shrink)

One of the most important issues concerning the foundations ofconscious perception centerson thequestion of whether perceptual consciousness is rich or sparse. The overflow argument uses a form of ‘iconic memory’ toarguethatperceptual consciousnessisricher (i.e.,has a higher capacity) than cognitive access: when observing a complex scene we are conscious of more than we can report or think about. Recently, the overflow argumenthas been challenged both empirically and conceptually. This paper reviews the controversy, arguing that proponents of sparse perception are committed to the (...) postulation of (i) a peculiar kind of generic conscious representation that has no independent rationale and (ii) an unmotivated form of unconscious representation that in some cases conflicts with what we know about unconscious representation.

What is Functionalism? Functionalism is one of the major proposals that have been offered as solutions to the mind/body problem. Solutions to the mind/body problem usually try to answer questions such as: What is the ultimate nature of the mental? At the most general level, what makes a mental state mental? Or more specifically, What do thoughts have in common in virtue of which they are thoughts? That is, what makes a thought a thought? What makes a pain a pain? (...) Cartesian Dualism said the ultimate nature of the mental was to be found in a special mental substance. Behaviorism identified mental states with behavioral dispositions; physicalism in its most influential version identifies mental states with brain states. Functionalism says that mental states are constituted by their causal relations to one another and to sensory inputs and behavioral outputs. Functionalism is one of the major theoretical developments of Twentieth Century analytic philosophy, and provides the conceptual underpinnings of much work in cognitive science. (shrink)

Let psychologism be the doctrine that whether behavior is intelligent behavior depends on the character of the internal information processing that produces it. More specifically, I mean psychologism to involve the doctrine that two systems could have actual and potential behavior _typical_ of familiar intelligent beings, that the two systems could be exactly alike in their actual and potential behavior, and in their behavioral dispositions and capacities and counterfactual behavioral properties (i.e., what behaviors, behavioral dispositions, and behavioral capacities they would (...) have exhibited had their stimuli differed)--the two systems could be alike in all these ways, yet there could be a difference in the information processing that mediates their stimuli and responses that determines that one is not at all intelligent while the other is fully intelligent.

This volume of Ned Block's writings collects his papers on consciousness, functionalism, and representationism. A number of these papers treat the significance of the multiple realizability of mental states for the mind-body problem -- a theme that has concerned Block since the 1960s. One paper on this topic considers the upshot for the mind-body problem of the possibility of a robot that is functionally like us but physically different -- as is Commander Data of _Star Trek's_ second generation. (...) The papers on consciousness treat such conceptual issues as phenomenal versus access consciousness, Dennett's theory of consciousness, and the function of consciousness, as well as such empirical matters as "How Not to Find the Neural Correlate of Consciousness," and an argument that there are distinct neural correlates for access consciousness and phenomenal consciousness. Turning to the mind-body problem, Block defends physicalism against Max Black's argument concerning phenomenal modes of presentation. The papers on representationism consider "mental paint" as well as the "Inverted Earth" thought experiment -- a world in which colors are reversed but there is a compensating reversal in the words that are used to describe them. _Consciousness, Function, and Representation_, bringing together papers that have appeared primarily in journals and conference proceedings, can be regarded as Block's most complete statement of his positions on consciousness.

This is my first publication of the distinction between phenomenal consciousness and access consciousness, though not using quite those terms. It ends with this: "The upshot is this: If Searle is using the access sense of "consciousness," his argument doesn't get to first base. If, as is more likely, he intends the what-it-is-like sense, his argument depends on assumptions about issues that the cognitivist is bound to regard as deeply unsettled empirical questions." Searle replies: "He refers to what he calls (...) an "access sense of consciousness." On my account there is no such sense.". (shrink)

Is consciousness based in prefrontal circuits involved in cognitive processes like thought, reasoning, and memory or, alternatively, is it based in sensory areas in the back of the neocortex? The no-report paradigm has been crucial to this debate because it aims to separate the neural basis of the cognitive processes underlying post-perceptual decision and report from the neural basis of conscious perception itself. However, the no-report paradigm is problematic because, even in the absence of report, subjects might engage in post-perceptual (...) cognitive processing. Therefore, to isolate the neural basis of consciousness, a no-cognition paradigm is needed. Here, I describe a no-cognition approach to binocular rivalry and outline how this approach can help resolve debates about the neural basis of consciousness. (shrink)

According to Conceptual Role Semantics, the meaning of a representation is the role of that representation in the cognitive life of the agent, e.g. in perception, thought and decision-making. It is an extension of the well known "use" theory of meaning, according to which the meaning of a word is its use in communication and more generally, in social interaction. CRS supplements external use by including the role of a symbol inside a computer or a brain. The uses appealed to (...) are not just actual, but also counterfactual: not only what effects a thought does have, but what effects it would have had if stimuli or other states had differed. The view has arisen separately in philosophy and in cognitive science. The source of the view is Wittgenstein and Sellars, but the source in contemporary philosophy is a series of papers by Harman and Field. Other proponents in philosophy have included Block, Horwich, Loar, McGinn and Peacocke. In cognitive science, they include Woods and Miller and Johnson-Laird. (shrink)

The "great debate" in cognitive science today is about the nature of mental images. One side says images are basically pictures in the head. The other side says they are like the symbol structures in computers. If the picture-in-the-head theorists are right, then computers will never be able to think like people.This book contains the most intelligible and incisive articles in the debate, articles by cognitive psychologists, computer scientists and philosophers. The most exciting imagery phenomena are described, phenomena that indicate (...) that mental images can be rotated and scanned, that smaller images are harder to see than larger ones, that when mental images are made larger they eventually overflow, that the "screen" they overflow from has a determinable shape (elliptical), and that this "screen" subtends a determinate visual angle, the angle of vision of the mind's eye.Such experiments cry out for explanation. If images are pictures in the head, who (or what) looks at them? Why haven't brain scientists found them? Such questions are the subject of the great debate.IMAGERY is an excellent choice for courses in cognitive psychology, perception: artificial intelligence, computer science; philosophy of mind, of psychology and of science; minds and machines, science and society.Contributors include: Roger Brown and Richard Herrnstein (on the work of Roger N. Shepard), Daniel Dennett, Jerry Fodor, Robert Schwartz, Stephen Kosslyn, Steven Pinker, George Smith, Steven Shwartz, and Zenon Pylyshyn,. (shrink)

Can we consciously see more items at once than can be held in visual working memory? This question has elud- ed resolution because the ultimate evidence is subjects’ reports in which phenomenal consciousness is filtered through working memory. However, a new technique makes use of the fact that unattended ‘ensemble prop- erties’ can be detected ‘for free’ without decreasing working memory capacity.

The greatest chasm in the philosophy of mind--maybe even all of philosophy-- divides two perspectives on consciousness. The two perspectives differ on whether there is anything in the phenomenal character of conscious experience that goes beyond the intentional, the cognitive and the functional. A convenient terminological handle on the dispute is whether there are.

The higher order approach to consciousness attempts to build a theory of consciousness from the insight that a conscious state is one that the subject is conscious of. There is a well-known objection1 to the higher order approach, a version of which is fatal. Proponents of the higher order approach have realized that the objection is significant. They have dealt with it via what David Rosenthal calls a “retreat” (2005b, p. 179) but that retreat fails to solve the problem.

consciousness comes about as a result of irritating nervous tissue, is just as unaccountable as the appearance of Djin when Aladdin rubbed his lamp.

endorsed one kind of inverted spectrum hypothesis and rejected another. This paper argues that the kind of inverted spectrum hypothesis that Wittgenstein endorsed is the thin end of the wedge that precludes a Wittgensteinian critique of the kind of inverted spectrum hypothesis he rejected. The danger of the dangerous kind is that it provides an argument for qualia, where qualia are contents of experiential states which cannot be fully captured in natural language. I will pinpoint the difference between the innocuous (...) and dangerous scenarios that matters for the argument for qualia, give arguments in favor of the coherence and possibility of the dangerous scenario, and try to show that some standard arguments against inverted spectra are ineffective against the version of the dangerous scenario I will be advocating. The leading idea of the paper is that an argument for qualia based on spectrum inversion does not require that the inversion be behaviorally indistinguishable. At one crucial point, I will rely on a less controversial version of an argument I gave in Block. Wittgenstein's views provide a convenient starting point for a paper that is much more about qualia than about Wittgenstein. (shrink)

In this note, I will discuss one issue concerning the main argument of Mind in a Physical World (Kim, 1998), the Causal Exclusion Argument. The issue is whether it is a consequence of the Causal Exclusion Argument that all macro level causation (that is, causation above the level of fundamental physics) is an illusion, with all of the apparent causal powers of mental and other macro properties draining into the bottom level of physics. I will argue that such a consequence (...) would give us reason to reject the Causal Exclusion Argument. But there is also a stronger challenge, the charge that, if there is no bottom level of physics, the Causal Exclusion Argument has the consequence that “causal powers would drain away into a bottomless pit and there wouldn’t be any causation anywhere.” (81--page numbers that are not attributed to other works are to Kim, 1998).
