Questions of criteria: Reply to Peterzell (1997)

In a reply to our report on hemispheric differences in processing band-pass filtered letters (Christman, Kitterle, & Niebauer, 1997), Peterzell (1997) argues that our results are not attributable to hemispheric asymmetries in spatial frequency processing. Rather, Peterzell argues that factors such as response criteria and stimulus visibility can account for our results. We argue that our results are attributable (at least in part) to hemispheric asymmetries in spatial frequency processing, while at the same time we acknowledge the potential influence of other factors in the determination of hemispheric differences.     

Ego development in the face of death: How being HIV positive affects movement through Erikson's adult stages of development

Erikson's epigenetic model of psychosocial development posits that each of eight stages unfolds in a particular sequence, and each becomes the primary issue of concern at specified times in the life cycle. Erikson does not address, nor could any empirical studies be located, exploring how the emergence of these eight stages might be affected by a diagnosis of terminal illness. The purpose of this study was to understand how an HIV-positive diagnosis affected movement through Erikson's stages of development. In-depth interviews were conducted with a sample of 18 HIV-positive men and women under 45 years of age. Analysis of the qualitative data revealed three findings regarding Erikson's stages: (1) The fifth stage of idenitity versus role confusion was revisted and the sense of self is redefined; (2) the three adulthood stages of intimacy versus isolation, generativity versus stagnation, and ego integrity versus depair were dealt with simulataneously and, in most cases, resolved favorably; and (3) intimacy and generativity enabled and supported the resolution of the tasks of identity and ego integrity.     

The Bahá'í Global Vision

The Bahá'í faith made a formal presentation to the Rio de Janeiro summit in 1992; this developed into the internationally published policy statement on global development issues, published in 1995, entitledThe Prosperity of Humankind. This article explores aspects of Bahá'í teaching on global development and conflict resolution highlighted both in this document, in the earlier The Promise of World Peace (1985), and in other writings. It examines key concepts such as consultation, justice, trusteeship, the unity in diversity of humankind, equality and equity, and planetisation. It explores the relevance of the Bahá'í vision to contemporary society, politics, business and religion, finding parallels in contemporary secular writings; and it questions whether dogmatic belief helps or hinders the process of global consultative development, that is whether future developments will be BaháY initiatives.     

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.     

A follow-up study of cognitive bias in generalized anxiety disorder

Patients with generalized anxiety disorder (GAD) without concurrent depression (n = 11) and normal controls (n = 17) were tested twice, about 2 months apart, on a modified Stroop colour-naming task, which presented anxiety-related, depression-related and neutral words in masked and unmasked exposure conditions. GAD patients received cognitive behaviour therapy in the test-retest interval, and were also retested at follow-up, about 20 months after initial testing. GAD patients showed interference in colour-naming negative words across both masked and unmasked conditions before treatment, but not post-treatment, compared with controls. Reduced interference effects of masked threat words over time correlated with reduced ratings of anxious thoughts at post-treatment, and at follow-up, in GAD patients. Thus, the preconscious bias for threat information in GAD appears to vary over time in association with changes in anxious thoughts and worries.
