The brain contains ubiquitous reciprocal bottom-up and top-down intercortical and thalamocortical pathways. These resonating feedback pathways may be essential for stable learning of speech and language codes and for context-sensitive selection and completion of noisy speech sounds and word groupings. Context-sensitive speech data, notably interword backward effects in time, have been quantitatively modeled using these concepts but not with purely feedforward models.

The central thesis of our target article is that feedback is never necessary in spoken word recognition. In this response we begin by clarifying some terminological issues that have led to a number of misunderstandings. We provide some new arguments that the feedforward model Merge is indeed more parsimonious than the interactive alternatives, and that it provides a more convincing account of the data than alternative models. Finally, we extend the arguments to deal with new issues raised by (...) the commentators such as infant speech perception and neural architecture. (shrink)

Auditory feedback perturbation studies have indicated a link between feedback and feedforward mechanisms in speech production when participants compensate for applied shifts. In spectral perturbation studies, speakers with a higher perceptual auditory acuity typically compensate more than individuals with lower acuity. However, the reaction to feedback perturbation is unlikely to be merely a matter of perceptual acuity but also affected by the prediction and production of precise motor action. This interplay between prediction, perception, and motor execution (...) seems to be crucial for the timing of speech and non-speech motor actions. In this study, to examine the relationship between the responses to temporally perturbed auditory feedback and rhythmic abilities, we tested 45 adult speakers on the one hand with a temporal auditory feedback perturbation paradigm, and on the other hand with rhythm perception and production tasks. The perturbation tasks temporally stretched and compressed segments (onset + vowel or vowel + coda) in fluent speech in real-time. This technique sheds light on the temporal representation and the production flexibility of timing mechanisms in fluent speech with respect to the structure of the syllable. The perception tasks contained staircase paradigms capturing duration discrimination abilities and beat-alignment judgments. The rhythm production tasks consisted of finger tapping tasks taken from the BAASTA tapping battery and additional speech tapping tasks. We found that both auditory acuity and motor stability in finger tapping affected responses to temporal auditory feedback perturbation. In general, speakers with higher auditory acuity and higher motor variability compensated more. However, we observed a different weighting of auditory acuity and motor stability dependent on the prosodic structure of the perturbed sequence and the nature of the response as purely online or adaptive. These findings shed light on the interplay of phonological structure with feedback and feedforward integration for timing mechanisms in speech. (shrink)

Actuator saturation phenomenon often exists in the actual control system, which could destroy the closed-loop performance of the system and even lead to unstable behavior. Our main contribution is to provide an antiwindup recursive dynamic surface control for a discrete-time system with an unknown state and actuator saturation. The fuzzy compensator is added to perform as an active disturbance rejection term in the feedforward path to avoid windup caused by input saturation. To construct output feedback control, the system (...) is transformed into the form of pure-feedback and an improved HOSM observer is designed to carry out future output prediction. Based on which RDSC is synthesized, only one fuzzy logic system is used and the controller singularity is completely avoided. In addition, the simulation and numeral examples using a continuous stirred tank reactors system with actuator saturation are provided and the results show that the strategy owns good robustness and effectively compensates for the disturbance caused by actuator saturation in the presence of a discrete-time system with an unmeasurable state.

A number of studies have shown that phonetic peculiarities, especially at the coarticulation level, exist in the disfluent as well as in the perceptively fluent speech of people who stutter (PWS). However, results from fluent speech are very disparate and not easily interpretable. Are the coarticulatory features observed in fluent speech of PWS a manifestation of the disorder, or rather a compensation for the disorder itself? The purpose of the present study is to investigate the coarticulatory behavior in the fluent (...) speech of PWS in the attempt to answer the question on its symptomatic or adaptive nature. In order to achieve this, we have studied the speech of 21 adult PWS (10 French and 11 Italian) compared to that of 20 fluent adults (10 French and 10 Italian). The participants had to repeat simple CV syllables in short carrier sentences, where C = /b, d, g/ and V = /a, i, u/. Crucially, this repetition task was performed in order to compare fluent speech coarticulation of PWS to that of PWNS, and to compare the coarticulation of PWS under a condition with normal auditory feedback (NAF) and under a fluency-enhancing condition due to an altered auditory feedback (AAF). This is the first study, to our knowledge, to investigate the coarticulation behavior under AAF. The degree of coarticulation was measured by means of the Locus Equations (LE). The coarticulation degree observed in fluent PWS speech is lower than that of the PWNS, and, more importantly, in AAF condition, PWS coarticulation appears even weaker than in the NAF condition. The results allow to interpret the lower degree of coarticulation found in fluent speech of PWS under NAF condition as a compensation for the disorder, based on the fact that PWS’s coarticulation is weakening in fluency-enhancing conditions, further away from the degree of coarticulation observed in PWNS. Since a lower degree of coarticulation is associated to a greater separation between the places of articulation of the consonant and the vowel, these results are compatible with the hypothesis that larger articulatory movements could be responsible for the stabilization of the PWS speech motor system, increasing the kinesthetic feedback from the effector system. This interpretation shares with a number of relatively recent proposal the idea that stuttering derives from an impaired feedforward (open-loop) control system, which makes PWS rely more heavily on a feedback-based (closed loop) motor control strategy.

Information processing that subserves conscious cognitive functions is thought to involve recurrent signaling through feedforward and feedback loops among hierarchically arranged functional regions of the cerebral cortex. In the current issue of Consciousness and Cognition, Lee et al. report that loss of consciousness, as produced by a bolus injection of the general anesthetic propofol to human volunteers, was accompanied by a decrease in wide-band EEG feedback connectivity from frontal cortex to parietal cortex, confirming a prediction from previous (...) experimental studies. Interestingly, frontoparietal feedback connectivity did not fully recover after the anesthetic effect wore off and the subjects first opened their eyes in response to a verbal command. Possible interpretations of the results and their implications with respect to the neural correlates of consciousness and unconsciousness are discussed. (shrink)

Extensive training with a musical instrument results in the automatisation of the bodily operations needed to manipulate the instrument: the performer no longer has to consciously think about the instrument while playing. The ability of the performer to automate operations on the instrument is due to sensorimotor mechanisms that can predict changes in the state of the body and the instrument in response to motor commands. But how strong are these mechanisms? To what extent can we alter the structure of (...) the instrument before they disappear? We performed an exploratory study to understand whether and how sensorimotor predictions survive instrument modification. We asked seven professional violinists to perform repertoire pieces and sight-reading exercises on four different violins: their own, a cheap violin, a small violin, and a violin whose strings had been put on in reverse order. We performed a series of quantitative investigations on performance intonation and duration, and on bowing gestures and errors. The analysis revealed that participants struggled adapting to the altered instruments, suggesting that prediction mechanisms are a function of instrument configuration. In particular, the analysis of bowing errors, intonation, and of performance duration suggested that the performance with the reverse violin was much less fluent and precise than the performer's own instrument; the performance with the small violin was also sub-standard though to a lesser extent. We also observed that violinists were differently affected by instrument modifications, suggesting that the capability to adapt to a new instrument is highly personal. (shrink)

This research examined the experiences of authors of academic journal articles in the educational sector of all eight universities in Finland. The ethical principles of peer review and best and worst review processes were in focus. Data were gathered by electronic questionnaire, which was completed by 121 respondents who represented well the heterogeneity of the staff in the educational sector. Out of nine ethical principles honesty, constructiveness, and impartiality were appreciated but promptness, balance, and diplomacy were criticized. According to two (...) open questions, a third of authors praised and blamed reviewers as experts and non-experts. The accuracy of feedback was more often present in the best rather than in the worst experienced review processes. Journals’ editors and their decision-making called forth more negative than positive accounts. The results were discussed in the context of ethical codes for reviewers and researchers’ findings regarding the ethical responsibilities to promote good science with thorough, appropriate, and honest feedback and feedforward.

In lieu of an abstract, here is a brief excerpt of the content:Better to Have No Deep Cut Anywhere in the Biopsychosocial SystemDerek Bolton, PhD (bio)It is very good to see theoretical work on the biopsychosocial model, acknowledging the causal role of these three kinds of factors in health and disease. I think Ongaro is right to argue that the biopsychosocial model requires an account of these three also being one—integrated—and that systems theoretic concepts such as dynamic, nonlinear causation are (...) helpful for capturing this. In a recent paper (Bolton, 2023) I have described Engel’s original (1997) paper as visionary but programmatic: visionary in seeing radical theory change afoot, citing von Bertalanffy’s new general system theory, but programmatic because the changes had not happened. The systems theoretic approach applies across the life, behavioral and social sciences, and typically envisages multiple interacting systems and causal pathways, including feedback and feedforward mechanisms, within and between systems. However, linear mechanisms are less complicated to research, and early social epidemiology used standard linear regression models (e.g., see the Whitehall II study [Marmot et al., 1991]). Such models do not capture non-linear connections in which the dependent variable also functions over time as an independent variable. However, the background theory typically would not exclude nonlinear dynamic causation, but on the contrary envisages it. Lower social status raises risk of ill health in a linear model, but it is also a plausible hypothesis that ill health in turn raises risk of lowering social status, which is testable in another or in a composite linear model. As well as social epidemiology, another large-scale theory change was underway at the time Engel wrote, the so-called cognitive revolution in psychology. Axiomatic in this shift was the idea that behavior is a response to the environment as perceived, thus merging the psychological/behavioral with the environmental, including the social. This latter point bears on Ongaro’s main proposal that the biopsychosocial model should envisage social causes as externalist, distinguished from the bio-psychological orientation of current psychiatry—and will be picked up below.Paper 2 makes some bold claims about the positive therapeutic value of construing causes [End Page 321] of mental health problems in external terms that have shared social meaning. These claims are made for functional neurological problems, but with extension to other kinds, in relation to a culture in which the shared social meanings refer to spirit possession, which, as a general type, is found in many non-modern Western cultures, as well as now, in our globalized world, in subcultures worldwide. One of the author’s claims is that within the spirit possession framework the shared framework of external causes enables society to adapt to the problem of living, to make it manageable, by shifting the social environment around the patient. As appropriate for ethnomethodology, there is no reference to controlled studies of outcome or mechanisms and I follow this immersed observational methodology here, with an experiential story that illustrates absence of personal and social acceptance and manageability of problematic conditions. While wandering recently with a friend in the mountains in the northern part of Africa, the local guide, in conversation in the local language and in English, having found out that two of us worked in “psychiatry/psychology,” asked us what we knew about; our brief reply included “obsessive-compulsive disorder” (OCD) and “anxiety”; the guide responded by asking whether OCD was washing hands a lot, and then wanted to discuss with us two people he knew well. One was a relation engaged, since many years, for many hours a day washing and cleaning, avoiding many daily tasks, sometimes childcare; friends and wider kinship structures had tried everything, except modern Western psychiatry (which was unavailable anyway), and, to put it briefly and colloquially, they were not at all happy about the person’s state and wished the person would get better. This person lived at a distance and we could not see them, so we do not know their view, but to judge by people with definite or probable OCD that we are familiar with, they may or may not have been happy in their reclusive state. Also to mention that the local healer had investigated... (shrink)

This is a sketch of the basis and role of consciousness and the minimally required elements and constraints of any setting that may produce consciousness. It proposes that consciousness (as we know it) is a biologically-mediated product of evolved recursive and hierarchically nested representational systems that obey information theoretic principles and Bayesian (probabilistic) feedback and feedforward predictive modeling processes.

The abstract basis of modern computation is the formal description of a finite state machine, the Universal Turing Machine, based on manipulation of integers and logic symbols. In this contribution to the discourse on the computer-brain analogy, we discuss the extent to which analog computing, as performed by the mammalian brain, is like and unlike the digital computing of Universal Turing Machines. We begin with ordinary reality being a permanent dialog between continuous and discontinuous worlds. So it is with computing, (...) which can be analog or digital, and is often mixed. The theory behind computers is essentially digital, but efficient simulations of phenomena can be performed by analog devices; indeed, any physical calculation requires implementation in the physical world and is therefore analog to some extent, despite being based on abstract logic and arithmetic. The mammalian brain, comprised of neuronal networks, functions as an analog device and has given rise to artificial neural networks that are implemented as digital algorithms but function as analog models would. Analog constructs compute with the implementation of a variety of feedback and feedforward loops. In contrast, digital algorithms allow the implementation of recursive processes that enable them to generate unparalleled emergent properties. We briefly illustrate how the cortical organization of neurons can integrate signals and make predictions analogically. While we conclude that brains are not digital computers, we speculate on the recent implementation of human writing in the brain as a possible digital path that slowly evolves the brain into a genuine (slow) Turing machine.

Magnuson, McMurray, Tanenhaus, and Aslin [Cogn. Sci. 27 (2003) 285] suggest that they have evidence of lexical feedback in speech perception, and that this evidence thus challenges the purely feedforward Merge model [Behav. Brain Sci. 23 (2000) 299]. This evidence is open to an alternative explanation, however, one which preserves the assumption in Merge that there is no lexical–prelexical feedback during on‐line speech processing. This explanation invokes the distinction between perceptual processing that occurs in the short term, (...) as an utterance is heard, and processing that occurs over the longer term, for perceptual learning.

We recently reported strong, replicable (i.e., replicated) evidence for lexically mediated compensation for coarticulation (LCfC; Luthra et al., 2021), whereby lexical knowledge influences a prelexical process. Critically, evidence for LCfC provides robust support for interactive models of cognition that include top‐down feedback and is inconsistent with autonomous models that allow only feedforward processing. McQueen, Jesse, and Mitterer (2023) offer five counter‐arguments against our interpretation; we respond to each of those arguments here and conclude that top‐down feedback provides (...) the most parsimonious explanation of extant data.

The Chorus representation is a sparse, similarity-preserving representation achieved by a feedforward neural network. Hence it is probably better suited for interpolation than for categorization. This commentary raises the question of how to combine categorization with interpolation, whether feedforward networks can be reasonable models for parts of the cerebral cortex, and whether people can perform more than one interpolation at a time.

Despite the recent surge in research on, and interest in, synesthesia, the mechanism underlying this condition is still unknown. Feedforward mechanisms involving overlapping receptive fields of sensory neurons as well as feedback mechanisms involving a lack of signal disinhibition have been proposed. Here I show that a broad range of studies of developmental synesthesia indicate that the mechanism underlying the phenomenon may involve reinstatement of brain activity in different sensory or cognitive streams in a way that is similar (...) to what happens during memory retrieval of semantically associated items. In the paper’s final sections I look at the relevance of synesthesia research, given the memory model, to our understanding of multisensory perception and common mapping patterns. (shrink)

The commentaries provide a multitude of perspectives on the theory of lexical access presented in our target article. We respond, on the one hand, to criticisms that concern the embeddings of our model in the larger theoretical frameworks of human performance and of a speaker's multiword sentence and discourse generation. These embeddings, we argue, are either already there or naturally forgeable. On the other hand, we reply to a host of theory-internal issues concerning the abstract properties of our feedforward (...) spreading activation model, which functions without the usual cascading, feedback, and inhibitory connections. These issues also concern the concrete stratification in terms of lexical concepts, syntactic lemmas, and morphophonology. Our response stresses the parsimony of our modeling in the light of its substantial empirical coverage. We elaborate its usefulness for neuroimaging and aphasiology and suggest further cross-linguistic extensions of the model. (shrink)

Frontoparietal connectivity has been suggested to be important in conscious processing and its interruption is thought to be one mechanism of general anesthesia. Data in animals demonstrate that feedforward processing of information may persist during the anesthetized state, while feedback processing is inhibited. We investigated the directionality and functional organization of frontoparietal connectivity in 10 human subjects anesthetized with propofol on two separate occasions. Multichannel electroencephalography and a computational method of assessing directed functional connectivity were employed. We demonstrate (...) that directed feedback connectivity is diminished with loss of consciousness and returns with responsiveness to verbal command. We also applied the Dendrogram classification method to assess the global organization of directed functional connectivity during consciousness and anesthesia. We demonstrate a state-specific hierarchy and subject-specific subhierarchy in functional organization. These data support the hypothesis that specific states of human consciousness are defined by specific states of frontoparietal connectivity. (shrink)

The information age can be dated to the work of Norbert Wiener and Claude Shannon in the 1940s. Their work on cybernetics and information theory, and many subsequent developments, had a profound influence on reshaping the field of psychology from what it was prior to the 1950s. Contemporaneously, advances also occurred in experimental design and inferential statistical testing stemming from the work of Ronald Fisher, Jerzy Neyman, and Egon Pearson. These interdisciplinary advances from outside of psychology provided the conceptual and (...) methodological tools for what is often called the cognitive revolution but is more accurately described as the information-processing revolution. Cybernetics set the stage with the idea that everything ranging from neurophysiological mechanisms to societal activities can be modeled as structured control systems with feedforward and feedback loops. Information theory offered a way to quantify entropy and information, and promoted theorizing in terms of information flow. Statistical theory provided means for making scientific inferences from the results of controlled experiments and for conceptualizing human decision making. With those three pillars, a cognitive psychology adapted to the information age evolved. The growth of technology in the information age has resulted in human lives being increasingly interweaved with the cyber environment, making cognitive psychology an essential part of interdisciplinary research on such interweaving. Continued engagement in interdisciplinary research at the forefront of technology development provides a chance for psychologists not only to refine their theories but also to play a major role in the advent of a new age of science.

I argue that Van der Velde and I agree on two fundamental issues surrounding the vision-related binding problem and recent solutions that have been offered: (1) that tagging theories fail to account for object feature binding in visual consciousness and (2) that feedforward-feedback processes in the visual cortical hierarchy play a role in generating a feature-unified object of visual consciousness. Van der Velde develops and discusses an important objection to tagging theories that could help to strengthen my critique (...) of neuronal synchrony (and other tagging theories) and then argues that the cognitive subject makes no explanatory contribution to the unity of an object’s features in visual consciousness. These issues are discussed in turn. By contrast, Van Leeuwen takes a more critical approach to my target article. A two-fold response to Van Leeuwen is offered: first, the root of Van Leeuwen’s perplexity is uncovered and then some specific objections that Van Leeuwen poses to my critique of neuronal synchrony, as a purported solution of the object feature binding problem, are addressed.

Social psychologists have evidence that evaluative feedback on others’ choices sometimes has unwelcome negative effects on hearers’ motivation. Holroyd’s article (Holroyd J. Ethical Theory Moral Pract 10:267–278, 2007) draws attention to one such result, the undermining effect, that should help to challenge moral philosophers’ complacency about blame and praise. The cause for concern is actually greater than she indicates, both because there are multiple kinds of negative effect on hearer motivation, and because these are not, as she hopes, reliably (...) counteracted by implicit features of praise and blame. The communicative ideal that she articulates does point us in the right direction, but it requires further elaboration. Once it is spelled out, we find that realizing this ideal, in light of the empirical research, requires rethinking the role of verdict-like judgments within moral feedback. (shrink)

This essay develops a theory of natural signs in order to show how evolutionary theory breathes new life into teleology. An argument to the contrary presented by Richard Taylor is refuted. The essay defends the view that the concept of negative feedback explicates purposiveness and that symbiotic evolution explains the occurrence of naturally adapted feedback systems. But evolution itself is not a teleological process, nor is it a negative feedback system. There is an exploration of the nature (...) of the dissatisfaction we feel with an evolutionary account of purposiveness from which the fortuitous cannot be eliminated. (shrink)

When navigating in a new environment, it is typical for people to resort to external guidance such as GPS, or people. However, in the real world, even though navigators have learned the route, they may still prefer to travel with external guidance. We explored how the availability of feedback and the source of external guidance affect navigation decision-making on experienced routes in the presence of external guidance. In three experiments, participants navigated a simulated route three times and then verbally (...) confirmed that they had learned it. They then travelled the same route again, accompanied with no, correct, or incorrect direction guidance, which latter two were provided by a GPS (Exp.1), a stranger (Exp.2), or a friend (Exp.3). Half of the participants received immediate feedback on their navigation decisions, while the other half without feedback did not know if they had selected the correct directions. Generally, without feedback, participants relied on external guidance, regardless of the direction sources. Results also showed that participants trusted the GPS the most, but performed best with their friends as a direction source. With feedback, participants did not show differences in performance between the correct and incorrect guidance conditions, indicating that feedback plays a critical role in evaluating the reliability of external guidance. Our findings suggest that incorrect guidance without any feedback might disturb navigation decision-making, which was further moderated by the perceived credibility of direction sources. We discuss these results within the context of navigation decision-making theory and consider implications for wayfinding behaviors as a social activity. (shrink)

The question of when and how bottom‐up input is integrated with top‐down knowledge has been debated extensively within cognition and perception, and particularly within language processing. A long running debate about the architecture of the spoken‐word recognition system has centered on the locus of lexical effects on phonemic processing: does lexical knowledge influence phoneme perception through feedback, or post‐perceptually in a purely feedforward system? Elman and McClelland (1988) reported that lexically restored ambiguous phonemes influenced the perception of the (...) following phoneme, supporting models with feedback from lexical to phonemic representations. Subsequently, several authors have argued that these results can be fully accounted for by diphone transitional probabilities in a feedforward system (Cairns et al., 1995; Pitt & McQueen, 1998). We report results strongly favoring the original lexical feedback explanation: lexical effects were present even when transitional probability biases were opposite to those of lexical biases.

With the increasing uncertainty in the external environment, exploratory innovation has gradually become the key path for enterprises to obtain core competitiveness and achieve sustainable growth. According to the behavioral theory of the firm, performance feedback is an essential driving factor affecting corporate innovation decisions. However, previous studies have ignored the consistency or inconsistency between historical and industry performance feedback, and its impact on exploratory innovation. Based on the data of Chinese companies listed from 2008 to 2019, this (...) paper explores the impact of consistency and inconsistency between historical and industry performance feedback on enterprises’ exploratory innovation. In the cases of consistency, this study finds that the scenario of historical performance shortfall-industry performance shortfall is more likely to promote enterprises’ exploratory innovation than the industry performance surplus-historical performance surplus; in the cases of inconsistency, compared with historical performance surplus-industry performance shortfall, the scenario of historical performance shortfall-industry performance surplus is more likely to promote enterprises’ exploratory innovation. Further research shows that regional institutional development enhances these relationships. This study enriches the driving factors of enterprises’ exploratory innovation from the perspective of multiple performance feedback, which can provide decision-making references for enterprises’ exploratory innovation strategies.

Feedback plays a crucial role in the writing processes. However, in the literature on foreign language writing, there is a dearth of studies that compare the effects of teacher feedback and automated feedback on both cognitive and psychological aspects of FL writing. To fill this gap, the current study compared the effects of teacher feedback and automated feedback on both revision quality and writing proficiency development, and perceived usefulness and perceived ease of use of the (...) feedback in English writing among English learners as an FL in China. It also investigated students’ perceptions of the strengths and weaknesses of the two types of feedback. The study adopted a mixed-methods design. The quantitative method collected the data through a pre-test and a post-test, which measured the participants’ English writing proficiency development; a writing task, which received either teacher feedback or automated feedback; and a close-ended questionnaire, which examined students’ perceived usefulness and perceived ease of use of the feedback. The qualitative method collected the data through an open-ended questionnaire, which examined the participants’ perceptions of the strengths and weaknesses of teacher feedback or automated feedback depending on the type of feedback they received. Chinese university EFLs in two English classes taught by the same English teacher participated in the study: one class received teacher feedback while the other received automated feedback using Pigaiwang. While the students in the two classes did not differ significantly on the pre-test of students’ writing proficiency, students who received teacher feedback scored significantly higher on revision than those who received automated feedback. Students in the teacher feedback class also had significantly higher ratings on perceived usefulness and perceived ease of use of the feedback than those in the automated feedback class. However, students in the automated feedback class obtained significantly higher scores on the post-test of the writing proficiency. The qualitative results identified three themes of strengths and two themes of weaknesses for the teacher feedback and the automated feedback, respectively. The results suggest that while teacher feedback has a more positive effect on the psychological aspect of FL writing, automated feedback may be more effective in developing FL writing proficiency in the long run.

Cognitive reflection, or the ability to inhibit intuitive and incorrect responses in favour of correct responses, predicts performance on a variety of cognitive tasks. The present study examined interventions to improve cognitive reflection. In two experiments, college students (N = 491) were assigned to one of three conditions, completed two versions of a cognitive reflection test (CRT), and then completed transfer tasks. Between the two CRTs, some participants were provided with elaborative feedback, others were instructed to consider additional responses (...) for their initial responses and the final group was a control. In both experiments, CRT performance increased between the first and second CRT in the feedback and instruction groups, but not in the control group. There was little evidence, however, for transfer to other tasks. These results suggest that cognitive reflection performance can be improved with brief interventions but that this improvement may not transfer to related tasks. (shrink)

Open peer commentary on the article “Radical Constructivist Structural Design Education for Large Cohorts of Chinese Learners” by Christiane M. Herr. Upshot: Herr’s thought-provoking approach to structural design education targets goals that include fostering the development of students’ intrinsic motivation and shifting the instructor’s role from one of dispensing knowledge to one of guiding students’ conceptual organization of their experiences. This commentary is intended to start a dialogue regarding the affordances and constraints of particular approaches to achieving these goals. In (...) particular, opportunities for self-generated feedback within the context of students’ productive activity and the use of models of individual student thinking to guide instructional planning are presented as promising possibilities.

Recent developments in psychology and neuroscience suggest away to link the mental phenomenon of visual awareness with specific neural processes. Here, it is argued that the feed-forward activation of cells in any area of the brain is not sufficient to generate awareness, but that recurrent processing, mediated by horizontal and feedback connections is necessary. In linking awareness with its neural mechanisms it is furthermore important to dissociate phenomenal awareness from visual attention or decision processes.
