Perceptual capacity of the isolated visual cortex in the cat

The split-brain approach was utilized in 6 cats to test the degree of functional autonomy in the visual system. The central visual cortex of one hemisphere was isolated by the removal of most of the extravisual neocortex of the same hemisphere. Visual inflow was restricted to the isolated side in four cases by sectioning the crossed optic fibres at the chiasma and masking one eye and in two cases by section of the contralateral optic tract. The isolation produced severe deficits in visual performance, although all cases retained some ability to learn and to recall simple pattern discriminations. The results of two- and three-stage removals of the non-visual cortex, and of terminal section of the callosum, as well as histology of the lateral geniculate nucleus indicated that geniculo-striate damage was not the limiting factor. Removal of fronto-parietal cortex produced as much or more decrement in visual discrimination than did removal of temporal cortex.     

Socio-Economic Status and Creativity: A Meta-Analysis

In the present study, we examined the relationship between socio-economic status (SES) and creativity through a meta-analysis of 885 effect sizes from 151 samples in 117 studies. Analyses of a multivariate model with a robust variance estimator showed a small positive correlation between creativity and SES (r = .120, 95% CI [0.086, 0.154]). Further analyses with four groups of moderators (i.e., creativity measure, SES indicator, sample characteristics, and study characteristics) indicated that the mean effect size is significantly higher when the creativity index is flexibility rather than fluency or when SES is measured by parental or one's own level of education and parental occupation rather than the location of residency. In addition, the relationship between creativity and SES dissipated as the students progressed from elementary school through college. The potential role of schooling in the creativity-SES link is discussed.     

Bibliotherapy and DCT: Co-Constructing the Therapeutic Metaphor

Bibilotherapy is presented as a strategy for cocreating therapeutic metaphors with clients. The use of these metaphors for promoting both first and second order change is enhanced when the metaphor is processed using Developmental Counseling and Therapy (DCT). Case examples are included to illustrate the combined use of these techniques.     

Gender and Age Patterns in Emotional Expression,Body Image,and Self-Esteem: A Qualitative Analysis

This qualitative study used written narrativesto examine gender and age patterns in body image,emotional expression, and self-esteem for a total of 209boys and girls in the fifth, eighth, and twelfth grades. Seventy-six percent of the sample wasCaucasian, 18% African-American, 5% Asian-American, and.5% Hispanic. A major finding indicates that boysrestrict emotional expression from early adolescence through late adolescence, while girls increaseemotional expression during the same age period. Anothermajor finding suggests that girls in late childhood andadolescence are both more negatively and more positively influenced than boys by body image.Both boys' and girls' feelings about themselves areprimarily influenced in gender-stereotypedways.     

Annotations of research and clinical perspectives on cluttering since 1964

In 1964, Deso Weiss published his landmark text Cluttering, after much persuasion by Charles Van Riper to put his thoughts in writing regarding this enigmatic speech and language disorder (Van Riper, personal communication, 1992). To our knowledge, Weiss's book was the only book in English devoted entirely to cluttering. Nearly 30 years later, a second text entitled Cluttering: A Clinical Perspective was published (Myers & St. Louis, 1992). The following annotations summarize nearly all that has been written on cluttering since Weiss's classic publication in 1964.     

The Dragonfly’s Web: Courseware for children created by college students on the World-Wide Web

We describe a successful approach to teaching first-year undergraduates to produce World-Wide Web courseware. Students were responsible for coding, writing, graphics, research, and theory. We taught that courseware should elicit higher order cognitive processes such as problem solving, application, synthesis, and critical thinking in children. It appears that the exercise facilitated experiential learning, the application of theories of learning, and courseware and hypertext design, as well as promoting critical thinking in our undergraduates. We argue that psychology students can and should develop useful Web pages as a learning experience and service to the field.     

From “Forgotten and Ignored” to Standards and Certification: Gerontological Counseling Comes of Age

The specialty of gerontological counseling has a 20-year history that began with a dearth of information and has progressed to the development of preparation standards and a national certification, both based on a nationally endorsed statement of competencies for gerontological counselors. The question of whether generalization or a specialization will best serve the needs of older persons continues to be central to the development of this specialization.
