There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had (...) fewer non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.

Claparède′s report of a case of amnesic syndrome is an early example of the cognitive neuropsychology paradigm, by which studies of brain-damaged patients are used to shed light on the nature of normal mental processes. The case illustrates the selective impairment of episodic memory, with procedural and semantic memory remaining intact. Moreover, the several demonstrations of preserved learning during amnesia comprise an early illustration of the dissociation between explicit and implict memory. However, its greatest contemporary relevance is (...) for theories of conscious recollection. Claparède underscored the role of the self, viewed as a knowledge structure, in conscious mental life, and he drew attention to three different modes of recognition: remembering, inferring, and knowing.

The processes whereby our brains continue to learn about a changing world in a stable fashion throughout life are proposed to lead to conscious experiences. These processes include the learning of top-down expectations, the matching of these expectations against bottom-up data, the focusing of attention upon the expected clusters of information, and the development of resonant states between bottom-up and top-down processes as they reach an attentive consensus between what is expected and what is there in the outside world. It (...) is suggested that all conscious states in the brain are resonant states and that these resonant states trigger learning of sensory and cognitive representations. The models which summarize these concepts are therefore called Adaptive Resonance Theory, or ART, models. Psychophysical and neurobiological data in support of ART are presented from early vision, visual object recognition, auditory streaming, variable-rate speech perception, somatosensory perception, and cognitive-emotional interactions, among others. It is noted that ART mechanisms seem to be operative at all levels of the visual system, and it is proposed how these mechanisms are realized by known laminar circuits of visual cortex. It is predicted that the same circuit realization of ART mechanisms will be found in the laminar circuits of all sensory and cognitive neocortex. Concepts and data are summarized concerning how some visual percepts may be visibly, or modally, perceived, whereas amodal percepts may be consciously recognized even though they are perceptually invisible. It is also suggested that sensory and cognitive processing in the What processing stream of the brain obey top-down matching and learning laws that are often complementary to those used for spatial and motor processing in the brain's Where processing stream. This enables our sensory and cognitive representations to maintain their stability as we learn more about the world, while allowing spatial and motor representations to forget learned maps and gains that are no longer appropriate as our bodies develop and grow from infanthood to adulthood. Procedural memories are proposed to be unconscious because the inhibitory matching process that supports these spatial and motor processes cannot lead to resonance. (shrink)

This paper uses the Process Dissociation Procedure to explore whether people can acquire unconscious knowledge in the serial reaction time task [Destrebecqz, A., & Cleeremans, A. . Can sequence learning be implicit? New evidence with the Process Dissociation Procedure. Psychonomic Bulletin & Review, 8, 343–350; Wilkinson, L., & Shanks, D. R. . Intentional control and implicit sequence learning. Journal of Experimental Psychology: Learning, Memory, and Cognition, 30, 354–369]. Experiment 1 showed that people generated legal sequences above baseline levels under (...) exclusion instructions. Reward moved exclusion performance towards baseline, indicating that the extent of motivation in the test phase influenced the expression of unconscious knowledge. Experiments 2 and 3 revealed that even with reward, adding noise to the sequences or shortening training led to above-baseline exclusion performance, suggesting that task difficulty and the amount of training also affected the expression of unconscious knowledge. The results help resolve some current debates about the role of conscious awareness in sequence learning. (shrink)

Learning and memory are inextricably intertwined. The capacity for learning presupposes an ability to retain the knowledge acquired through experience, while memory stores the background knowledge against which new learning takes place. During the dark years of radical behaviorism, when the concept of memory was deemed too mentalistic to be a proper subject of scientific study, research on human memory took the form of research on verbal learning (Anderson, 2000; Schwartz & Reisberg, 1991).

The phenomenon of ‘Deep Learning,’ which has given us such science-fiction-like innovations as self-driving cars, as well as visual search tools in photographic applications, is a new form, and subset, of ‘Machine Learning’ made possible by very recent innovations in computing. Machine Learning itself has been around for some decades – essentially pattern-recognition software that requires very substantial computing resources, which were, until recently, mostly theoretical and hard to come by. Machine Learning was one avenue of the field of Artificial (...) Intelligence known as Narrow A.I. – the kind of ‘artificial intelligence’ that was strictly limited in scope as a first-steps starting point of what came, as a result, to be known as General A.I. General A.I., known then as simply, ‘Artificial Intelligence’, was the 1950s dream that brought us such things as Robbie the Robot, and more recently C3PO, and The Terminator: the kind of science fiction characters that remain the only manifestations of General Artificial Intelligence. -/- ‘Deep Learning’ also continues engineering’s 1940s trend of using language in a way that I will contest in this paper: a co-opting of words that have been used, in the past, to describe human activities, using them instead to describe what engineers have managed to make machines do. These co-optations reduce the richness of the word, making its referent an algorithm: a flow diagram that represents the bare essentials of what an engineer can understand and reproduce of a human activity; not the human activity itself. This diagram of the ‘engineering possible’ over-simplifies the human activity it tries to depict. With continued usage, the meaning of the word for us today has all-too-often become reduced to what the engineer has newly defined it to mean: something much less than it once was. -/- In this paper I attempt to roll back some of these co-optations, and to re-introduce some of the richness of the words that have been taken by engineering. I examine Turing’s seminal paper on the notion of a thinking machine. I use the philosophical insights of Henri Bergson, especially in his book, Matter and Memory, and the discoveries of neuroscience and complexity scientists. I try to show that the answer to Turing’s question, ‘Can machines think?’ remains a resounding, ‘No!’, and that notions such as ‘deep learning’ are in fact not only an inaccurate use of the very human experience of learning, but degrade the latter in using such a term.

Veit suggests that the challenge of coordinating movement in multicellular organisms led to the evolution of a prioritizing value system, which rendered organisms complex enough to be sentient and drove the Cambrian explosion, while the absence of this evaluation system led to the demise of Ediacaran animals. In this commentary we criticize Veit’s terminology and evolutionary proposals, arguing that his terminology and evolutionary scenarios are problematic, and put forward alternative proposals. We suggest that sentience is a system property, and that (...) the evolution of sentience was the outcome of the evolution of open-ended associative learning, which included the coevolution of sensory, motor, memory, and value subsystems. We suggest that these coevolutionary system dynamics were a factor in the Cambrian explosion and contributed to the extinction of the Ediacaran biota. (shrink)

This paper argues that self-awareness emerges in organisms whose brains have a sufficiently integrated, complex ability for associative learning and memory. Continual sensory input of information related to the organism leads to the formation of a set of associations that may be termed an organismal “self-image”. After providing the basic mechanistic basis for the emergence of an organismal self-image, this paper proceeds to go through a representative list of behaviors associated with self-awareness, and shows how associative memory and (...) learning, combined with an organismal self-image, leads to the emergence of these various behaviors. This paper also discusses various tautologies that invariably emerge when discussing self-awareness. We continue with various speculations on manipulating self-awareness, and discuss how concepts from set and logic theory may provide a useful set of tools for understanding the emergence of higher cognitive functions in complex organisms.

In lieu of an abstract, here is a brief excerpt of the content:Memory and Justice:Narrative Sources of Community in Camus's The First ManJohn Randolph LeBlancThere as a certain frustration involved in trying to find Albert Camus's conception of justice in express positive statements. But inasmuch as Camus saw his work in the trope of journey, his complex set of ideas about justice are to be discerned in the narrative structure of his texts. This is particularly so in his last (...) work, the incomplete autobiographical The First Man.1 In the novel, Camus has his protagonist and fictional self Jacques Cormery seek the sources of his orientation to questions of love and justice by attempting to reconstruct the brief life of a father he never knew. It is in the life reconstructed, chiefly through the recollected memories of those who knew the man that Jacques comes to understand his own responses to questions of love and justice. A necessary by-product of the process is that through his questioning, Jacques recreates a community of which he is a product but, until the journey is undertaken, he has never been a part. His journey is, thus, one of self-discovery and inextricably ties justice to community formation. Camus's last novel, I will argue, suggests the importance of memory and narrative to the fundamental questions of political theory, particularly, questions regarding community-formation and the role and nature of justice.IContemporary reflections on the nature of politics take narrative encounters with reality seriously. The significance of narrative to political theory is, I think, tied to the Augustinian recognition that, temporally speaking, we live forward but learn backwards. It is through reconstructing [End Page 140] our experiences as individuals that we learn about who we are and how we got here. Recent political theory has come to recognize that this epistemological structure works at both the individual and the communal level. Michael Walzer, for example, has suggested that a community's culture is the story its members tell so as to make sense of the different pieces of their social life and justice is the doctrine that distinguishes the pieces.2 But distinguishing the pieces can mean and has meant blocking or restricting our access to that reconstruction. While a time-honored political practice, the impulse to control the contents of the narrative by deeming it unworthy or too dangerous to speak became a self-conscious political practice and a particularly dangerous phenomenon in the last century. Controlling the contents of narrative means control in past, present, and future tense. Memory can become a site of resistance because narrative depends on memory for its points of reference. What gets narrated gets remembered. Most often, what does not get narrated either gets lost or must find another way.Narrative and memory have always been political resources, Joshua Foa Dienstag suggests in his important work on memory and narrative in political theory, but the self-conscious control of them is dangerous.3 At the end of a century wherein we perpetrated much we might be tempted to forget, it is increasingly evident that we must remember before we can speak of justice, that is, our stories must be told and heard before we can reconstitute (or re-member) a functional conception of political community. It is in these terms that I want to talk about narrative and its relationship to political community and justice. But what is silenced is as important as what is articulated. Dienstag, who reads political theory as narrative, suggests that, practically speaking, what we have learned is that memory unarticulated is even more dangerous than memory manipulated. Memory unarticulated either festers and becomes a flashpoint for turmoil or is articulated by an interest for its own ends and becomes a tool of control if not oppression. In either case, memory is bastardized to the ends of power politics and distinguishing between authentic and inauthentic experiences becomes the province of politicians. Leaving these distinctions to politicians, I want to suggest, is risky business. When memory represents the absence of a set of experiences rather than their presence, we are confronted by the end of a community rather than its beginning.All cultures, Walzer suggests, have an interest in...

Statistical properties in the visual environment can be used to improve performance on visual working memory tasks. The current study examined the ability to incidentally learn that a change is more likely to occur to a particular feature dimension and use this information to improve change detection performance for that dimension . Participants completed a change detection task in which one change type was more probable than others. Change probability effects were found for color and shape changes, but not (...) location changes, and intentional strategies did not improve the effect. Furthermore, the change probability effect developed and adapted to new probability information quickly. Finally, in some conditions, an improvement in change detection performance for a probable change led to an impairment in change detection for improbable changes. (shrink)

Time plays a central role in consciousness, at different levels and in different aspects of information processing. Subliminal perception experiments demonstrate that stimuli presented too briefly to enter conscious awareness are nevertheless processed to some extent. Implicit learning, implicit memory, and conditioning studies suggest that the extent to which memory traces are available for verbal report and for cognitive control is likewise dependent on the time available for processing during acquisition. Differences in the time available for processing (...) also determine not only the extent to which one becomes conscious of action, but also provides the basis for making attributions of authorship to experienced acts. In this paper, we offer a brief overview of these different findings and suggest that they can all be understood based on the fact that consciousness takes time. From this perspective, the availability of representations to conscious awareness depends on the quality of these representations — the extent to which they are strong, stable in time, and distinctive. High-quality representations occur when processes of global competition have had sufficient time to operate so as to make the system settle into the best possible interpretation of the input. Such processes implement global constraint satisfaction and critically depend on reentrant processing, through which representations can be further enriched by high-level constraints. We discuss these ideas in light of current theories of consciousness, emphasizing the fact that consciousness should be viewed as a process rather than as a static property associated with some states and not with others.

I argue that the function of episodic memory is to store information about the past, against the orthodox view that it is to support imagining the future. I show that episodic memory is epistemically generative, allowing organisms to learn from past events retroactively. This confers adaptive benefits in three domains: reasoning about the world, skill, and social interaction. Given the role of evolutionary perspectives in comparative research, this argument necessitates a radical shift in the study of episodic (...) class='Hi'>memory in nonhumans. (shrink)

Among the scientific disciplines to be impacted by postmodernity will be the study of consciousness, not only in theory but in research and practice. Narratives, key aspects of postmodern approaches, are already replacing abstract generalizations in theoretical formulations about such aspects of consciousness as memory and imagination. Research studies, both quantitative and qualitative, can be looked upon as attempts to tell stories that yield new information. The use of narrative in psychotherapy can be seen as the co-construction (...) of life stories by the therapist and the client. Post-modernity requests that scientists question their own assumptions, and learn from non-Western perspectives, alternative conscious states, and narratives of exceptional human experiences. Twenty propositions are offered for a postmodern project in the study of consciousness that would entail utilizing narratives that are embedded in a time and a place - and the constant evaluation and questioning of the usefulness of these narratives.

All civilian, government-sponsored spacecraft, despite ostensibly having the primary purpose of scientific data-collection, are, within the advanced cultures that produce them, primarily symbolic objects, created by the people as a means of indicating, both to themselves and to all the world, what is in their hearts: what they value. These craft are a statement that we value learning, exploration, adventure, difficult endeavors, teamwork, precision, self-discipline, and intelligence. All such spacecraft are, fundamentally, semiotic objects. The fact that they collect data, although (...) proffered as their primary function, is in fact secondary. In this paper I propose a thought-experiment, involving consideration of a spacecraft expressly intended for a symbolic, semiotic, psychological purpose: a kind of interstellar library, a Noah's Ark of Documents, the "Milky Way Messenger." By taking an idea that was originally merely a concept to be featured in a science-fiction story and exploring whether it might be feasible to accomplish it in the real world, the paper is intended to trigger thought and discussion concerning the conscious creation of such objects. The paper concludes with suggestions concerning the semiotic psychological function of certain government programs. (shrink)

This paper discusses the ways in which anesthetic agents can be used to investigate the role of awareness in learning and memory. It reviews research into learning during light, subclinical anesthesia, termedhypesthesia.This research suggests that the effects of anesthetics on implicit and explicit memory are roughly comparable, although implicit memory for simple stimuli may resist the effects of very low doses of anesthetic. In addition, this paper reports experimental data demonstrating that long-term retention of information is prevented (...) by doses of anesthetic that are low enough to permit awareness and even short-term memory of auditory stimuli. Overall, these findings are consistent with the hypothesis that frontal lobe function is particularly sensitive to anesthetics. They raise theoretical and practical questions about the necessity of consciousness for learning and about interpretation of the evidence for learning during surgery under general anesthesia.

We describe an experiment that investigated levels-of-processing effects in recognition memory for famous faces. The degree of conscious control over the recognition decisions was manipulated by using a response deadline procedure, and memory awareness associated with those decisions was assessed using a standard remember-know paradigm. Levels-of-processing effects were found at both short and long response deadlines, and at both deadlines those effects occurred only in remembering. Moreover, knowing, as well as remembering, increased with the greater opportunity for conscious (...) control over recognition decisions at the long deadline. These results have implications for dual-process theories that distinguish between a slower, more controlled recollection process, reflected in remembering, and a faster, more automatic familiarity process, reflected in knowing.

Working memory, an important posit in cognitive science, allows one to temporarily store and manipulate information in the service of ongoing tasks. Working memory has been traditionally classified as an explicit memory system – that is, as operating on and maintaining only consciously perceived information. Recently, however, several studies have questioned this assumption, purporting to provide evidence for unconscious working memory. In this paper, we focus on visual working memory and critically examine these studies as (...) well as studies of unconscious perception that seem to provide indirect evidence for unconscious working memory. Our analysis indicates that current evidence does not support an unconscious working memory store, though we offer independent reasons to think that working memory may operate on unconsciously perceived information.

The aim of this article was to provide experimental evidence that classical dissociation between levels of consciousness associated with memory retrieval can be explained in terms of task dependency and distinctiveness of traces. In our study phase, we manipulated the level of isolation of the memory trace by means of an isolation paradigm . We then tested these two types of isolation in a series of tasks of increasing complexity: a lexical decision task, a recognition task, and (...) a free recall task. The main result of this study was that distinctiveness effects were observed as a function of the type of isolation and the nature of the task. We concluded that trace distinctiveness improves subsequent access to the trace, while the level of trace distinctiveness also appears to determine the possibility of conscious or explicit retrieval.

This is the second of four online Companions to Velmans, M. (ed.) (2018) Consciousness (Critical Concepts in Psychology), a 4-volume collection of Major Works on Consciousness commissioned by Routledge, London. -/- The Companion to Volume 2 Part 1 focuses on the detailed relationship of phenomenal consciousness to mental processing described either functionally (as human information processing) or in terms of neural activity, in the ways typically explored by cognitive psychology and cognitive neuroscience. Beginning with reviews of functional (...) differences between unconscious, preconscious and conscious processing and the different senses in which mental processing can be said to be “conscious”, the readings turn to seminal work on blindsight and related phenomena, experimental evidence of perception without awareness, ways to combine “subjective” and “objective” measures of awareness, evidence for distinct neural pathways governing visual awareness and visual control of motor acts, and the complex ways in which consciousness of action relates to both voluntary and involuntary acts. The readings then focus on the intimate links between attention and consciousness, starting with the writings of William James and surveying the extensive work on this subject over the last 60 years that explores the relationships between and attended and non-attended processing, preconscious and conscious processing, and attention, primary (working, short-term) memory and consciousness. The readings go on to survey the evidence that attention contributes to the “neural binding” required for an integrated conscious experience and evidence that attention (in humans) is dissociable from consciousness, necessary for consciousness, but not sufficient for consciousness. The readings then turn to research on “inattentional blindness”, and conclude with a review of Baars’ global workspace theory, which integrates many theories and findings in this area into a coherent, global model. The Companion then summarises seminal readings on learning, memory and consciousness; the extensive research on mental imagery, long thought to epitomize private, subjective conscious experience—and consequently ruled out of science by reductive, materialist philosophies of mind; the complex relations of consciousness to sleep and dreaming; the development of consciousness in human infants; and the debates surrounding, and extensive evidence for consciousness in non-human animals, with attendant consequences for their humane treatment. -/- As with the other Companions to these Volumes there are many links to background resources (marked in pink) and to the selected readings themselves (marked in blue).

Although Descartes’s ideas regarding consciousness and memory have been studied extensively, few attempts have been made to address their systemic relations. In order to redress this deficiency, I argue in favor of three interrelated theses. The first is that intellectual memory has a crucial role to play in Descartes’s concept of consciousness, especially when it comes to explaining higher forms of consciousness. Second, the connection between memory and consciousness has been obscured by the (...) fact that intellectual memory, taken as a subject in its own right, was relatively neglected in Descartes’s philosophy: By and large, his views on the matter remained within the limits of late scholastic Scotism. Third, what makes the question of intellectual memory so fascinating in Descartes is not some ground-breaking insight into its nature; rather, it is his gradual recognition of the role that intellectual memory plays in the constitution of higher forms of consciousness. With these arguments, and relying on Descartes’s 1648 correspondence with Antoine Arnauld, where he progressed beyond the substance-based approach to the self, I try to show that he deserves to be credited with a more prominent status in the history of the self and personhood than has previously been the case.

Processes comparable in important respects to those underlying human conscious and non-conscious processing can be identified in a range of species and it is argued that these reflect evolutionary precursors of the human processes. A distinction is drawn between two types of processing: stimulus-based and higher-order. For ‘higher-order,’ in humans the operations of processing are themselves associated with conscious awareness. Conscious awareness sets the context for stimulus-based processing and its end-point is accessible to conscious awareness. However, the mechanics of the (...) translation between stimulus and response proceeds without conscious control. The paper argues that higher-order processing is an evolutionary addition to stimulus-based processing. The model’s value is shown for gaining insight into a range of phenomena and their link with consciousness. These include brain damage, learning, memory, development, vision, emotion, motor control, reasoning, the voluntary versus involuntary debate, and mental disorder. (shrink)

Philosophical theories of memory rarely distinguish between importantly different sorts of memory: procedural, semantic and episodic. I argue for a temporal representation theory to explain the unique characteristic of episodic memory as the only form of conscious memory. A careful distinction between implicit and explicit representation shows how the past figures in memory. In procedural and semantic memory, the influence of the past is implicit by which I mean that the past experience is used (...) but not represented in the skill or knowledge. Episodic memory, in contrast, depends on representing a past experience as past. On a temporal representation theory of consciousness, a conscious state represents the present moment, and in the case of episodic memory, it includes a representation of past experience. The embedded account of the ‘feeling of pastness’ takes past experience to be part of the explicit content of a conscious state. An episodic memory is a representation of the present that includes a representation of the past. Whereas a higher-order theory of consciousness can give no reason why only episodic memories are conscious, a temporal theory explains why episodic memories are both higher-order and conscious. Finally, I consider the essential role of episodic memory in the formation of a temporally extended self. The demands of a social environment motivate development of an ability to track the mental states of others and oneself over time. By incorporating past experience (and future experience) into the present, episodic memory extends experience in time to form the sense of self. Through a careful examination of the function of temporal representation, we can see why the past is not consciously represented in procedural and semantic memory and the value of consciously representing the past in episodic memory.

I examine the phenomenon of implicit learning, the process by which knowledge about the rule-governed complexities of the stimulus environment is acquired independently of conscious attempts to do so. Our research with the two seemingly disparate experimental paradigms of synthetic grammar learning and probability learning, is reviewed and integrated with other approaches to the general problem of unconscious cognition. The conclusions reached are as follows: Implicit learning produces a tacit knowledge base that is abstract and representative of the structure of (...) the environment; such knowledge is optimally acquired independently of conscious efforts to learn; and it can be used implicitly to solve problems and make accurate decisions about novel stimulus circumstances. Various epistemological issues and related problems such as intuition, neuroclinical disorders of learning and memory, and the relationship of evolutionary processes to cognitive science are also discussed.

Lidz also ponders the theory of syntactic bootstrapping by asking why it is that learners are considered to retain little of extralinguistic environments (i.e., their observations) during word learning, while being able to retain detailed representations of linguistic context, for example, the multiple syntactic frames in which a verb appears. Lidz argues that learners value syntactic information over extralinguistic context from the beginning of learning, consistent with syntactic bootstrapping as a key device for verb learning.

Although considerable attention has been paid to the possible involvement of sleep in memory processing, there is no substantial evidence for it. Walker describes a phenomenon of consolidation-based enhancement (CBE), whereby performance on select procedural tasks improves with overnight sleep; that is, without additional practice on the tasks. CBE, however, appears restricted to a few tasks, and even with these tasks CBE is not confined to sleep but also occurs during wakefulness. Sleep serves no unique role in this process. (...) At best, CBE is a slow, time-dependent process of consolidation that begins with task acquisition in waking and can under some circumstances extend to sleep. (shrink)

Of all the problems facing science none are more challenging yet fascinating than those posed by consciousness. In The Science of Consciousness leading researchers examine how consciousness is being investigated in the key areas of cognitive psychology, neuropsychology and clinical psychology. Within cognitive psychology, special focus is given to the function of consciousness, and to the relation of conscious processing to nonconscious processing in perception, learning, memory and information dissemination. Neuropsychology includes examination of the neural (...) conditions for consciousness and the effects of brain damage. Finally, mind/body interactions in clinical and experimental settings are considered, including the somatic effects of imagery, biofeedback and placebo effects. Every chapter is written by an expert in the field. They each provide a clear overview of existing research along with an exciting new synthesis of consciousness studies. The The Science of Consciousness will be invaluable for students, researchers and clinicians interested in the developments and directions of this rapidly growing field. (shrink)
