The Role of Consciousness in Memory

Conscious events interact with memory systems in learning, rehearsal and retrieval (Ebbinghaus 1885/1964; Tulving 1985). Here we present hypotheses that arise from the IDA computional model (Franklin, Kelemen and McCauley 1998; Franklin 2001b) of global workspace theory (Baars 1988, 2002). Our primary tool for this exploration is a flexible cognitive cycle employed by the IDA computational model and hypothesized to be a basic element of human cognitive processing. Since cognitive cycles are hypothesized to occur five to ten times a second and include interaction between conscious contents and several of the memory systems, they provide the means for an exceptionally fine-grained analysis of various cognitive tasks. We apply this tool to the small effect size of subliminal learning compared to supraliminal learning, to process dissociation, to implicit learning, to recognition vs. recall, and to the availability heuristic in recall. The IDA model elucidates the role of consciousness in the updating of perceptual memory, transient episodic memory, and procedural memory. In most cases, memory is hypothesized to interact with conscious events for its normal functioning. The methodology of the paper is unusual in that the hypotheses and explanations presented are derived from an empirically based, but broad and qualitative computational model of human cognition

"Consciousness". Selected Bibliography 1970 - 2001

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience (Metzinger 1995a, b). From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001

Linguistic and metalinguistic categories in second language learning

This paper discusses proposed characteristics of implicit linguistic and explicit metalinguistic knowledge representations as well as the properties of implicit and explicit processes believed to operate on these representations. In accordance with assumptions made in the usage-based approach to language and language acquisition, it is assumed that implicit linguistic knowledge is represented in terms of flexible and context-dependent categories which are subject to similarity-based processing. It is suggested that, by contrast, explicit metalinguistic knowledge is characterized by stable and discrete Aristotelian categories which subserve conscious, rule-based processing. The consequences of these differences in category structure and processing mechanisms for the usefulness or otherwise of metalinguistic knowledge in second language learning and performance are explored. Reference is made to existing empirical and theoretical research about the role of metalinguistic knowledge in second language acquisition, and specific empirical predictions arising out of the line of argument adopted in the current paper are put forward. © Walter de Gruyter 2008

Consciosusness in Cognitive Architectures. A Principled Analysis of RCS, Soar and ACT-R

This report analyses the aplicability of the principles of consciousness developed in the ASys project to three of the most relevant cognitive architectures. This is done in relation to their aplicability to build integrated control systems and studying their support for general mechanisms of real-time consciousness.\ud To analyse these architectures the ASys Framework is employed. This is a conceptual framework based on an extension for cognitive autonomous systems of the General Systems Theory (GST).\ud A general qualitative evaluation criteria for cognitive architectures is established based upon: a) requirements for a cognitive architecture, b) the theoretical framework based on the GST and c) core design principles for integrated cognitive conscious control systems

Habitual reflexivity and skilled action

Theorists have used the concept habitus to explain how skilled agents are capable of responding in an infinite number of ways to the infinite number of possible situations that they encounter in their field of practice. According to some perspectives, habitus is seen to represent a form of regulated improvisation that functions below the threshold of consciousness. However, Bourdieu (1990) argued that rational and conscious computation may be required in situations of ‘crises’ where habitus proves insufficient as a basis for our actions. In the current paper, I draw on a range of evidence which indicates that conscious intervention (including self-reflective sensory consciousness) is required not only at points of crises but also as skilled performers engage in the mundane actions/practices that characterise their everyday training and performance regimes. The interaction of conscious learning and unconscious schemata leads to the development of a reflexive habitus which allows performers to refine and adapt embodied movement patterns over time

Modulation of Long-Term Memory by Arousal in Alexithymia: The Role of Interpretation

Moderate physiological or emotional arousal induced after learning modulates memory consolidation, helping to distinguish important memories from trivial ones. Yet, the contribution of subjective awareness or interpretation of arousal to this effect is uncertain. Alexithymia, which is an inability to describe or identify one’s emotional and arousal states even though physiological responses to arousal are intact, provides a tool to evaluate the role of arousal interpretation. Participants scoring high and low on alexithymia (N = 30 each) learned a list of 30 words, followed by immediate recall. Participants then saw either an arousing (oral surgery) or neutral video (tooth brushing). Memory was tested 24-h later. Physiological response to arousal was comparable between groups, but subjective response to arousal was impaired in high alexithymia. Yet, delayed word recognition was enhanced by arousal regardless of alexithymia status. Thus, subjective response to arousal, i.e., cognitive appraisal, was not necessary for memory modulation to occur

The Tenants' Movement: the domestication and resurgence of a social movement in English housing policy

The launch of a National Tenants Voice for the English social housing sector rekindles a contentious debate among housing scholars over the role played by class and material interest in the mobilisation of collective action. The clear suggestion in the declaration of a National Tenants Voice is that tenants in the fragmented and residualised social housing sector share certain common interests that can be mobilised around, represented and promoted and that there exists a tenants’ movement that is effective to some degree in negotiating at national policy level. The contention that common interests rooted in class or sectoral divisions engender political conflict was the dominant theme in the application of Marxist and Weberian theory to the struggles of social housing tenants in the 1970s and early 1980s. This thesis was debunked in the 1990s when the restructuring of the social housing sector made the assumption of shared interests and common cause between tenants impossible to maintain. The return of the concept of shared interests applied to a tenants’ movement makes it necessary to re-examine the treatment of tenant collective action in academic studies. This paper explores the concept of material interest as applied to housing struggles and provides a new analysis of the mobilisation of tenant collective action. It concludes in setting out an interpretive framework based on social movement theory to guide further study into the mobilisation, aims and effectiveness of the tenants’ movement and its role in English housing policy

The Developmental Path of the Lawyer

My mother does not drive, and I own a towel that I cannot use-these are my reasons for studying law. I am an integrated tapestry of elation and disappointment, risk and reward, ambiguity and conviction .. .. I discovered [through adversity] that transitional challenges were not permanent impediments to my progress, but were instead emboldening catalysts to my personal evolution and professional development. These two stories come from admissions essays submitted by members of Georgetown University Law Center\u27s class of 2014, recently published in the Law Center\u27s alumni magazine. The published essays provide fascinating views into the personal experiences and deep reflection that lead people to pursue legal studies
