Neural predictive mechanisms and their role in cognitive incrementalism

Many neuroscientists view prediction as one of the core brain functions, especially on account of its support of fast movements in complex environments. This leads to the natural question whether predictive knowledge forms the cornerstone of our common-sense understanding of the world. However, there is little consensus as to the exact nature of predictive information and processes, or of the neural mechanisms that realize them. This paper compares procedural versus declarative notions of prediction, examines how the brain appears to carry out predictive functions, and discusses to what degree, and at what level, these neural mechanisms support cognitive incrementalism: the notion that high-level cognition stems from sensorimotor behavior.     

The Work Process as Spatial Situation: A Sketch

Interacting with the work of art entails a spatial situation, which is double. On a mental plane it is encapsulated reverie, on a physical plane it is production and consumption. These two are woven together as an orthogonal text or texture. The space of the work of art thus contains both the process of its making and its viewing. Seen as a dimensional space it is non linear. It is characterized by oscillations, discepancies, misalignements, multiplicity and recurrence. There is a correspondance between the studio and the exhibition area, as well as a dialogue between privileged and unprivileged spaces. The situation has something in common with oneiric space, where weightlessness and gravity oscillate.     

The Elusive General Factor of Personality: The Acquaintance Effect

A general factor (g_p) at the apex of personality has been suggested to account for the correlations between the Big Five. Although the g_p has received ample support from monomethod studies, results from studies incorporating different methods have remained rather ambiguous; some have identified a g_p across different informants, whereas others have not. It was hypothesized that these divergent findings are a result of varying lengths of acquaintance between raters. To this end, the current study presents a multitrait multi‐informant meta‐analysis (total N = 11 941) that found weak support for a g_p as a substantive trait of personality. Evidence for a g_p was susceptible to the length of acquaintance between informants. Although a g_p could be identified for short‐term acquaintances, it remained elusive at long‐term acquaintance. Thus, the g_p in other ratings more likely reflects normative ratings of an average individual rather than ratings of the specific target person.

Justifying Desires

According to an influential conception of reasons for action, the presence of a desire or some other conative state in the agent is a necessary condition for the agent's having a reason for action. This is sometimes known as internalism. This article presents a case for the considerably stronger thesis, which we may call hyper‐internalism, that the presence of a desire is a sufficient condition for the agent's having a (prima facie) reason for action.     

Buddhist prajÑĀ and Greek sophia

The present review examines five books, one by a non-Baha'i, three by a Baha'i academic, and one by a Baha'i non-academic. The non-Baha'i volume, which is very short, is by a Danish sociologist of religion, Margit Warburg. It forms a solid explanatory text informed by a lengthy experience of the Baha'is both in Denmark and abroad. This review discusses, inter alia, three volumes by a Baha'i sociologist, Peter Smith. While the three titles are very different books, taken together they form an intelligent presentation of the religion from the perspective of a thoughtful insider. Finally, the article looks at a completely different sort of book, an intelligent portrayal of Baha'ism from its spiritual and moral perspectives by Moojan Momen. This last brings readers closest to typical fare for believers and new converts.     

On creating a psychoanalytic mind

The term process knowledge is introduced to highlight a particular way of analyzing that centers on how our patients gain knowledge. It is suggested that analyzing with heightened awareness to process knowledge is crucial for the patients' capacity for self-analysis, and differs from helping patients primarily gain knowledge of their unconscious fantasies and conflicts as the primary curative factor in psychoanalysis.     

Individual Differences in the Encoding Processes of Egocentric and Allocentric Survey Knowledge

This study examined how different components of working memory are involved in the acquisition of egocentric and allocentric survey knowledge by people with a good and poor sense of direction (SOD). We employed a dual‐task method and asked participants to learn routes from videos with verbal, visual, and spatial interference tasks and without any interference. Results showed that people with a good SOD encoded and integrated knowledge about landmarks and routes into egocentric survey knowledge in verbal and spatial working memory, which is then transformed into allocentric survey knowledge with the support of all three components, distances being processed in verbal and spatial working memory and directions in visual and spatial working memory. In contrast, people with a poor SOD relied on verbal working memory and lacked spatial processing, thus failing to acquire accurate survey knowledge. Based on the results, a possible model for explaining individual differences in spatial knowledge acquisition is proposed.     

Shock tactics to counter AIDS: The australian experience

Abstract

The use of shock tactics to motivate people to learn more about AIDS and to take appropriate protective action characterised the approach adopted by the national health authorities in Australia during 1987. The rationale underlying this approach is critically examined, particularly in the light of results obtained from surveys of community concern and knowledge about AIDS in the state of South Australia before the campaign and after it had been in progress for some five months. Contrary to expectations no significant increases in either personal or social concern were found; in fact, among older respondents personal concern had decreased significantly. Levels of knowledge about AIDS, in general, remained unchanged, apart from an increase in acceptance of the safety of blood transfusions from a very low to a somewhat higher level. Among a minority of respondents (29%) who approved of the campaign and also believed they had been influenced by it, personal and social concern about AIDS, but not knowledge, was significantly greater than among others. The view that fear-inducing techniques can be used to bring about increases in knowledge about AIDS was not supported, although some positive effects on the social attitudes of respondents most affected by the campaign are suggested.     

Magnitude and determinants of behavioral risk reduction: Longitudinal analysis of a cohort at risk for AIDS

The magnitude and predictors of longitudinal behavioral change are reported in a cohort of homosexual men at risk for AIDS. Self-reports of sexual behavior were obtained at two points in time separated by an interval of approximately six months. These self-reports were used to construct both dichotomous and continuous measures of changes in behavior consistent with reduction in the transmission of the AIDS virus (HIV). Although there was considerable variability in behavior. mean changes were consistently in the desired direction. Avoidance of anonymous sexual partners, monogamy, and modification of receptive anal sex to reduce exposure to semen by condom use or withdrawal prior to ejaculation appeared to be especially important in this cohort. Both multiple linear regression and multiple logistic regression were used to examine the relationship between a model of health behavior and these outcomes. Variables examined included knowledge of AIDS. perceived risk of AIDS. the perceived efficacy of behavior in reducing AIDS risk, difficulties with sexual impulse control, belief in biomedical technology to provide a prevention or cure, social norms supportive of behavioral change, and gay network affiliation. Of all these factors, only the availability of supportive peer norms was consistently, significantly and positively related to multiple measures of outcome. Differences between these analyses and longitudinal analyses reported elsewhere are discussed. These results suggest the policies regarding HIV antibody testing should be developed cautiously. taking account of the failure of a sense of risk to predict subsequent behavioral change. They also emphasize the important role of gay organizations in developing social norms supportive of behavioral risk reduction.     

Women's views about intimate examinations and sexually inappropriate practices by their general practitioners

Abstract

The aim of this survey of 472 adult women was to assess women patients' feelings about intimate examinations and their perceptions and experiences of sexually inappropriate medical practice. Two-thirds of women preferred a women doctor for intimate examinations. Slightly more than two-thirds found intimate examinations embarrassing and stressful, and strongly expressed the need for information and on-task, health-related comments during these examinations. General personal comments or non-medical touching were not particularly welcomed, even for the purpose of comforting the patient. There was a range of views about patients' personal relationships with doctors, with the lines between acceptable and unacceptable behaviour somewhat ambiguous. A small but significant number of women perceived that they had been sexually harassed (5%) or abused (3%) by a doctor, with this experience more common for non-English speaking women. Results were discussed in terms of implications for improved doctor practice, particularly during intimate examinations and with vulnerable patients.
