Conscious recollection appears to be governed by seven principles: elaboration, organization, time‐dependency, cue‐dependency, encoding specificity, schematic processing, and reconstruction. However, these same principles may not apply to unconscious, or implicit, memory. Implicit memory is most commonly reflected in priming effects which occur in the absence of conscious recollection. Dissociations between explicit and implicit memory have been observed in patients suffering various sorts of brain damage, in other forms of amnesia, in behavioral performance of neurologically intact subjects, (...) and in brain‐imaging studies of memory. The most popular interpretation of these dissociations holds that explicit and implicit memory are mediated by separate and independent brain systems. However, there are also compelling interpretations in terms of dual processes operating on the contents of a single memory system. (shrink)

Butler’s idea of evolution was developed over the publication of four books, several articles and essays between 1863 and 1890. These publications, although never achieving the success expected by Butler, proposed a psychological elaboration of evolution, called ‘unconscious memory’. This was strongly in contrast with the materialistic approach suggested by Darwin’s natural selection. Starting with a historical introduction, this paper aspires to ascertain the logic, meaning and significance of Butler’s idea of ‘unconscious memory’ in the post-Darwinian (...) physiological and psychological Pan-European discussion. Particular attention is devoted to demonstrating that Butler was not only a populariser of science but also an active protagonist in the late Victorian psychological debate. (shrink)

Studies investigating memory for events during anesthesia show a confusing pattern of positive and negative results. To establish whether there are any consistent patterns of findings across studies, we conducted a meta-analysis of the data from 2517 patients in 44 studies. The meta-analysis included two measures of the effects of positive suggestions on postoperative recovery: the duration of postoperative hospitalization and the amount of morphine administered via patient-controlled anesthesia, as well as two measures of memory for specific information (...) presented during anesthesia: direct tests and indirect tests. The meta-analysis indicated that positive suggestions presented during anesthesia have little or no effect on postoperative recovery. On the other hand, the meta-analysis showed that specific information is remembered following surgery, as long as testing is not delayed longer than 36 h. Studies of memory for events during anesthesia provide a useful avenue for exploring unconscious cognition. (shrink)

Subjects classified visible 2-digit numbers as larger or smaller than 55. Target numbers were preceded by masked 2-digit primes that were either congruent (same relation to 55) or incongruent. Experiments 1 and 2 showed prime congruency effects for stimuli never included in the set of classified visible targets, indicating subliminal priming based on long-term semantic memory. Experiments 2 and 3 went further to demonstrate paradoxical unconscious priming effects resulting from task context. For example, after repeated practice classifying 73 (...) as larger than 55, the novel masked prime 37 paradoxically facilitated the “larger” response. In these experiments task context could induce subjects to unconsciously process only the leftmost masked prime digit, only the rightmost digit, or both independently. Across 3 experiments, subliminal priming was governed by both task context and long-term semantic memory. (shrink)

_Memory, Myth, and Seduction_ reveals the development and evolution of Jean-Georges Schimek's thinking on unconscious fantasy and the interpretive process derived from a close reading of Freud as well as contemporary psychoanalysis. Contributing richly to North American psychoanalytic thought, Schimek challenges local views from the perspective of continental discourse. A practicing psychoanalyst, teacher, and consummate Freud scholar, Schimek sought to clarify Freud's concepts and theories and to disentangle complexities borne of inconsistencies in Freud's assumptions and expositions. This book is (...) divided thematically into three sections. The first concerns fantasy and interpretation as they play out in the analytic situation, and the manner in which analyst and patient coconstruct meaning and reconstruct and recover memory. The second consists of two seminal papers which provide the sequence of steps in the five revisions in Freud's seduction theory. Schimek's careful scholarship lays out the data of Freud's writing, which allows one to draw one's own conclusions about the implications of the changes in the theory that he made. In the third, more theoretical section, he provides a foundation for understanding many of today's discussions about unconscious fantasy, dreaming, remembering, consciousness, affect, self-reflection, mentalization, and implicit relational knowing. He clarifies and illustrates Freud's original formulations through a careful reading of sections of _The Interpretation of Dreams_, and a study of Freud's famous Signorelli parapraxis. Skillfully arranged and carefully edited by Deborah Browning and including a foreword by Alan Bass, this collection of Schimek's published and unpublished papers will be of interest to practicing psychoanalysts, psychoanalytically-oriented psychotherapists, and students of the history of ideas and philosophy who have a particular interest in fantasy, interpretation, and Freud.

One method for investigating the neurobiology of consciousness is to experimentally manipulate consciousness as a variable and then visualize the resultant functional brain changes with advanced imaging techniques. To begin investigation into this area, healthy volunteers underwent positron emission tomography scanning while listening to randomized word lists in both conscious and unconscious conditions. Following anaesthesia, subjects had no explicit memories. Nonetheless, subjects demonstrated implicit memory on a forced-choice test . These subsequent memory scores were correlated with regional (...) brain metabolism measured during encoding. Conscious recall and unconscious recognition memory demonstrated considerable anatomic overlap in correlating significantly with relative glucose metabolism in auditory verbal memory areas. However, only conscious recall correlated with mediodorsal thalamic nucleus activity; unconscious recognition memory did not. These findings suggest that conscious versus unconscious memory distinctions may depend on the presence or absence of correlated thalamic activity, and directly implicate the thalamus in the neurobiology of consciousness.

The work of Hussefl and Freud had common sources in the philosophy, psychology and physiology of the nineteenth century. Herbart, Brentano, Helmholtz, Fechner, Wundt and Mach were among the towering figures in their common background who had influence on their respective work. 1 Although contemporaries who had little concern for the other's professional interest, Husserl and Freud nevertheless struggled with some common problems. One of these is the relationship of sensation to memory and to the experience of time. The (...) concepts of sensation, memory and time were, in fact, artifacts which the empirical methods of nerve-physiology, the psychophysical testing of sensory thresholds, as well as the metaphysics and positivism of the late nineteenth century had left them.

When subjects give higher confidence or memory ratings to a test word in a recognition test, do they simply raise their criterion without making better discrimination, or do they raise both criterion and true discrimination between the studied words and the lures? Given that previous studies found subjects’ false alarm responses to lures slower than to SW, and recognition latency inversely correlated with the confidence rating, can the latency difference between the lures and SW be accounted for by confidence (...) or memory ratings? The present results showed that when subjects gave higher confidence or memory ratings, both their bias and sensitivity were raised, indicating that they could consciously distinguish the lures from the SW. However, a latency difference between true and false recognitions persisted after confidence and memory ratings were held constant, suggesting an unconscious source of discrimination between the two types of memory.

Changes in the conscious and unconscious influences of memory over time were assessed in two experiments by using a variant of the process-dissociation procedure. In both experiments, performance on a stem-completion task was measured under both inclusion and exclusion instructions. Across the two experiments, there were four different retention intervals: 2 minutes, 2 days, 2 weeks, and 2 months. The results indicated that conscious influences decreased systematically across retention interval. In contrast, unconscious influences of memory in (...) the absence of conscious influences increased between 2 minutes and 2 days, and then remained relatively stable from 2 days to 2 weeks to 2 months. These results stand in apparent contrast to those of McBride and Dosher (1999), which showed equal rates of forgetting for conscious and unconscious influences of memory on performance. The implications for models of the relation between conscious and unconscious influences of memory on performance are discussed. (shrink)

There is no dispute over the existence of functions and processes that operate outside consciousness. No one knows what his or her liver is doing, and we all shed a tear when Lassie comes home, even though we know we are watching a movie with a dog who responds to off‐camera signals. Where matters become interesting (and contentious) is over such issues as whether unconscious processes are routinized and inflexible – in a word, stupid – or whether they can (...) be seen as sophisticated, flexible, and adaptive – in a word, intelligent. In the cognitive sciences, until recently, the former perspective dominated for reasons which are rooted not in any objective data base, but in philosophical considerations. The long‐standing presumption of a not‐very‐bright unconscious is, we suspect, the end product of a continuing adherence to Lockean and Cartesian epistemic traditions. While proponents of these two orientations didn't agree on much, they were of one mind with regard to the proposition that that which is mental is conscious. Contemporary psychologists and philosophers who feel comfortable with this position tend to view unconscious cognitive processes as low‐level, crude, primitively connectionistic, and rather stupid, since they equate sophisticated control operations with the functions of consciousness.

Erdelyi does us all a great service by his customarily incisive discussion of the various ways in which our field tends to neglect, confuse, and misunderstand numerous critical issues in attempting to differentiate conscious from unconscious perception and memory. Although no single commentary could hope to comprehensively assess these issues, I will address Erdelyi’s three main points: How the dissociation paradigm can be used to validly infer unconscious perception; The implications of below-chance effects; and The role of (...) time. I suggest that significant progress on construct validity issues is possible; below-chance effects are part of a more general bidirectional phenomenon, very likely unconscious, and do not threaten absolute subliminality; and practice/learning effects pose potential difficulties for time-based dissociation paradigms.

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.

A clarification of Husserl's changing conceptions of imaginary consciousness ( phantasy ) and memory, especially at the level of auto-affective time-consciousness, suggests an interpretation of Freud's concept of the Unconscious. Phenomenology of consciousness can show how it is possible that consciousness can bring to present appearance something unconscious, that is, something foreign or absent to consciousness, without incorporating it into or subordinating it to the conscious present. This phenomenological analysis of Freud's concept of the Unconscious leads (...) to a partial critique of Freud's metapsychological determination of the Unconscious as a simple, internally unperceived representational consciousness. It also suggests an account of how a reproductive inner consciousness can free the subject from the experience of anxiety by allowing for possibilities of self-distanciation and symbolic self-representation that protect the subject from traumatic affection by and through its own instinctual drives.

In two experiments the conditions of, and the processes leading to, gender biases in fame judgments were investigated. In Experiment 1, the gender bias was not reduced in a condition that alerted participants to the gender of the names. In Experiment 2, participants' sex-role orientation, but not their gender, was related to the gender bias. The process dissociation procedure was used in both experiments in an attempt to separate conscious and unconscious memory processes contributing to the gender bias. (...) Using L. L. Jacoby's original measurement model there appeared to be evidence for unconscious influences on the gender bias in fame judgments. Unfortunately, this evidence disappeared when a model was used that takes guessing and, hence, response biases into account, which confirms that measurement models that ignore response biases in the process dissociation procedure may lead to erroneous conclusions.

Weaving together state-of-the-art research, theory, and clinical insights, this book provides a new understanding of the unconscious and its centrality in human functioning. The authors review heuristics, implicit memory, implicit learning, attribution theory, implicit motivation, automaticity, affective versus cognitive salience, embodied cognition, and clinical theories of unconscious functioning. They integrate this work with cognitive neuroscience views of the mind to create an empirically supported model of the unconscious. Arguing that widely used psychotherapies--including both psychodynamic and cognitive (...) approaches--have not kept pace with current science, the book identifies promising directions for clinical practice. Subject areas/Key words: unconscious processes, human consciousness, psychoanalysis, psychoanalytic theory, implicit learning, implicit memory, implicit motivation, automaticity, cognition, subconscious, psychodynamic psychotherapy, mind, computational neuroscience, empirical research Audience: Clinical psychologists, psychiatrists, psychoanalysts, and other mental health practitioners, as well as researchers and students of clinical and personality psychology and psychopathology.

The main goal of this article consists in addressing two fundamental issues of consciousness research and cognitive science, namely, the question of why declarative memory functions are inextricably linked with phenomenal awareness and the question of the physical basis of memory traces. The presented approach proposes that high-level cognitive processes involving consciousness employ a universal mechanism by means of which they access and modulate an omnipresent background field that is identified with the zero-point field (ZPF) specified by stochastic (...) electrodynamics, a branch of physics that deals with the universal principles underlying quantum systems. In addition to its known physical properties and memory capacities, the ZPF is hypothesized to be an immanently sentient medium. It is propounded that linking up to a particular field mode of the ZPF activates a particular phenomenal nuance, implying that the phase-locked coupling of a set of field modes, i.e., the formation of a so-called ZPF information state, constitutes an appropriate mechanism for the amalgamation of elementary shades of consciousness into a complex state of consciousness. Since quantum systems rest exactly on this mechanism, conscious memory processes in the brain are expected to differ from unconscious processes by the presence of the typical features of many-body quantum systems, particularly long-range coherence and attractor formation, which is supported by a huge body of empirical evidence. On this basis, the conceptual framework set out in this article paves the way for a new understanding of the brain as a write-read head interacting with the ZPF, leading to self-consistent interpretations of the neural correlates of memory formation and memory retrieval and explaining why these memory processes are closely intertwined with phenomenal awareness. In particular, the neural correlates suggest that the brain produces consciously perceived memory traces by writing sequences of information states into the ZPF and retrieves consciously experienced memory traces by reading sequences of information states from the ZPF. Using these theoretical foundations, altered states of consciousness and memory disorders can be traced back to impairments of the ZPF write-read mechanism. The mechanism should reveal itself through characteristic photon emissions, resulting in testable predictions. (shrink)

From whence spring the sparks of creativity? It is to this very question that the field of depth psychology--especially that of C.G. Jung and his intellectual descendants--has much to contribute. Just as the Muses were the offspring of Mnemosyne, the goddess of memory, our memories are the ancestors of our creativity that finds its multifaceted expression in the written word, image, theater, dance, and music. The Unconscious Roots of Creativity seeks to push the investigation into that domain of (...) memory that is beyond our conscious reach. With articles from 16 contributors, the "red thread" running through each of the offerings in this volume is that, whatever its ultimate expression, the creative impulse has its roots deep in the psyche.

In Koriat's paper ''The Feeling of Knowing: Some Metatheoretical Implications for Consciousness and Control,'' he asserts that the feeling of knowing straddles the implicit and explicit, and that these conscious feelings enter into a conscious control process that is necessary for controlled behavior. This assertion allows him to make many speculations on the nature of consciousness itself. We agree that feelings of knowing are produced through a monitoring of one's knowledge, and that this monitoring can affect the control of behavior (...) such as whether or not to search memory for an answer. Further, we believe that monitoring of performance with a strategy can also affect cognition control and strategy selection; however, we also believe that frequently this monitoring and control occurs without conscious awareness. Feeling of knowing has received an inordinate amount of attention because it lies behind the highly recognizable tip-of-the-tongue phenomenon that represents one of the rare cases of conscious monitoring. There are other feelings of knowing which are much more common and are not accompanied by conscious awareness. These are evident in the early selection of a strategy for answering a problem. In our view, the research on feeling of knowing will not resolve the question of whether consciousness is merely epiphenomenal. (shrink)

Scholars have known for some time that Plotinus' treatment of memory forms an important part of his philosophy; and while there are various points of view from which his doctrine can be approached, one seems singularly important. His analysis of memory boldly contrasts conscious and unconscious behaviour in human beings and so materially advances our knowledge of his concept of conscious experience.

In recent decades it has become increasingly clear that a substantial amount of cognitive work goes on independent of consciousness. The research has been carried out largely under two rubrics, implicit learning and implicit memory. The former has been concerned primarily with the acquisition of knowledge independent of awareness and the latter with the manner in which memories not readily available to conscious recall or recognition play a role in behavior; collectively these operations comprise the essential functions of the (...) cognitive unconscious. This paper reviews the recent history of work on these issues, identifies some of the problems confronting researchers, and introduces a theoretical framework based on principles of evolutionary biology within which to view them. The argument is that the cognitive unconscious, despite its apparent sophistication, is of considerable evolutionary antiquity and antedates conscious cognitive systems by a considerable amount of time. Various entailments of this evolutionary perspective are explored including such issues as phylogeny and ontogeny of implicit processes, the robustness of the implicit functions as displayed by the capacity to resist disruptions from psychological and neurological disorders, the relationship between implicit cognition and intelligence, and individual differences in implicit cognitive abilities.
