Commentary on high-performance computing and human vision II: Virtual reality and eyeball tracking

Visualization of scientific data that are not normally visible can be greatly enhanced by understanding human visual perception. Mars the Movie illustrated the use of stereo resolution for producing realistic vistas of the Mars surface. The real-time recording and analysis of eyeball-tracking data is another example of human vision research which benefits from high-performance computing. Currently the bottleneck is not in the hardware but in the available software to transform data efficiently.     

HOME ACCESS MODIFICATIONS: EFFECTS ON COMMUNITY VISITS BY PEOPLE WITH PHYSICAL DISABILITIES

We examined the effects of access modifications to home entrances of people with physical disabilities on their reported community outings. An interrupted time-series design was used, in which the introduction of ramps was staggered across the homes of 6 people with moderate to severe mobility impairments. Four participants reported increases in weekly outings following installation of ramps at their entrances, and 2 reported a small decrease. These findings suggest that reducing the response requirements of access to and from the residence of people with mobility impairments may increase community visits, but may be insufficient given other environmental barriers in the community.     

Subordinate Performance, Leader-Subordinate Compatibility, and Exchange Quality in Leader-Member Dyads: A Field Study

A model examining factors related to quality of exchange in leader-member dyads was developed and tested. Subordinates and supervisors in 223 dyads in a manufacturing setting provided demographic data and completed measures of performance and attitude towards work. Results found organization citizenship behaviors, leader-member attitude similarity, and similarity of education to be related to quality of leader-member exchange.     

Configurational approach to manifest dream analysis: Possible acceleration of the patient's communication in psychoanalytic psychotherapy

This paper presents an approach to dream analysis utilizing the manifest content of a number of consecutive dreams from the same patient. Following a review of the literature, it is noted that in once-a-week psychotherapy there is often very little time for exhaustive dream analysis to unravel the buried meanings within the latent dream content. Twenty categories have been established for the configurational analysis, which is applied to the analysis of the first eleven dreams of a patient in psychoanalytic psychotherapy. The authors independently analyzed the patient's dreams using each of the 20 categories with high reliability, then combined their contributions. This data was then compared with the treating analyst's independent clinical observations about the twenty categories.     

Contextual determinants of strategic choice: Some moderators of the availability bias

Three studies explored how the influence of the ‘availability heuristic’ on frequency judgement is mediated and moderated by the perceived meaning of the task, the perceived relevance of information for the task, and the salience of differential memorability of information. All studies adapted the ‘fumous names ’paradigm (Tversky and Kahneman, 1973) in which subjects are required to listen to a list of names of known personalities of both sexes and then judge the frequency of men and women. The availability heuristic (Tversky and Kahneman, 1973) posits that classes whose instances are easy to imagine or recall will be perceived as relatively frequent, so that when names of one sex are more famous and thus memorable this category will be rated as more numerous even when it occurs less frequently. Consistent with the notion that the use of availability is sensitive to task interpretation, we showed that the availability effect is eliminated over successive trials (Study 1) and moderated when task instructions render different categories salient (Study 2). In the third study it is shown that conditions which facilitate awareness of the biasing relationship between gender and fame (memorability), decrease the use of the availability heuristic by moderating frequency estimates of the more famous category. Results of these studies emphasize the context-bound and strategic aspects of judgement.     

Postmodernism versus psychotherapy

‘Postmodernism’has made a substantial impact on various schools of psychotherapy, including family therapy.‘Postmodern’therapists tend to focus on the productive capacities of language, developing narrative styles for their work.‘Postmodern’family therapy is differentiated from modernist approaches by its disavowal of truth claims and its encouragement of alternative‘voices’or narratives. In this paper, it is argued that this represents too narrow an approach to psychotherapy and to postmodernism. Postmodernism takes as a central concern the limits of symbolization, so a postmodernist therapy would deal primarily with failures of language. Language-based therapeutic procedures such as those to be found in family therapy are consequently not postmodernist. This state of affairs should be welcomed, as a truly‘postmodern’mode of therapy would probably celebrate irrationality.     

The body-as-object versus the body-as-process: Gender differences and gender considerations

The present study analyzed the influence that gender and gender concepts have on predominantly white young adults' attitudes toward their body parts (body-as-object) and body functions (body-as-process). Results indicated that, regardless of gender, participants held more positive attitudes toward their body functions than toward body parts. Masculinity was positively related to body-as-object attitudes, yet this relationship was true only for women. As expected, femininity had exactly the opposite effect on women's body-as-object attitudes. Unexpectedly, femininity was found to be positively related to men's body-as-object attitudes. Regarding the body-as-process, although no attitudinal gender differences were found, masculinity had a significant positive correlation. Finally, results suggested that what may partly account for the more positive body esteem expressed by males than females in previous research are that men appear to hold a higher percentage of neutral attitudes toward their body parts and women hold a higher percentage of negative attitudes.I would like to thank Paul Sweeney and Dean McFarlin for their statistical advice in calculating regression equations for different values of the moderator variable
