Multivariate genetic analysis of specific cognitive abilities in the Colorado adoption project at age 7

A multivariate hierarchical model of specific cognitive abilities was fitted to data from 7-year-old adopted and nonadopted sibling pairs in the Colorado Adoption Project in order to assess differential genetic influence on specific mental abilities. Model fitting results and Schmid-Leiman (Schmid & Leiman, 1957) transformations reveal significant heritable variation for verbal, spatial, and memory factors independent of general cognitive ability for the eight ability tests examined. In contrast, environmental influences are primarily measure-specific. The results suggest genetic effects in middle childhood that differentially influence mental ability scores.     

Visual hemispheric asymmetries depend on which spatial frequencies are task relevant

Observers classified sine-wave and square-wave gratings on the basis of fundamental frequency (Are the bars wide or narrow?) or on the basis of higher harmonic frequencies (Are the bars sharp or fuzzy?). Stimuli were presented in either the left (LVF) or right (RVF) visual field. When the classification was made on the basis of the fundamental frequencies (1 or 3 c/deg), there was a LVF/right hemisphere advantage. However, when the classification was on the basis of a sharp/fuzzy distinction which involved searching for the higher harmonic frequencies, then a RVF/left hemisphere advantage was found.     

Electroencephalogram asymmetry during emotionally evocative films and its relation to positive and negative affectivity

The purpose of the present study was to determine if there were differences in hemispheric lateralization during the experience of emotions and if those differences were related to personality style. College-age adult subjects selected for high positive and negative affectivity on Tellegen's Multidimensional Personality Questionnaire (MPQ; Tellegen, 1982) viewed video stimuli selected for their emotionally evocative nature and rated the intensity of the emotions they experienced. The ongoing electroencephalogram (EEG) was recorded while they watched the video clips. Analyses of the EEG data revealed that there were differences in regional activation during the emotional video clips, especially for those stimuli selected to elicit either happy or disgust emotions. These results support the hypothesis that the right hemisphere is specialized for the experience of certain negative affects, whereas the left hemisphere is specialized for the experience of certain positive affects. The findings also indicated some support for the theory that individual differences in personality style are related to differing levels of hemispheric arousal.     

Effects of a Communication Skills Training Programme on the Cognitions of Careers Guidance Students

Traditionally, communication skills training has focused principally on overt behaviours that are clearly identifiable. In recent years there has been an increasing awareness that cognitive processes can have considerable influence on behaviour. An attempt was made to establish whether changes in cognitions occurred as a result of a behaviourally-based communication skills training programme in which there had been no explicit attempt to bring about such cognitive changes. More specifically, the study examined whether such a programme resulted in changes in aspects of the personal construct space of students on a Diploma in Careers Guidance course. The results offered some support for the hypothesis that the programme produced changes in the students' personal construct space.     

Home,school, and playroom: Training grounds for adult gender roles

Gender differences in children's play activities, preferred school subjects, and occupational goals were examined in relation to such parental variables as toy-giving and chore assignment. Subjects were 245 children in grades K, 3, 6, and 8. Subjects completed questionnaires before and after Christmas asking what gifts they wanted, asked for, received, and liked best. They also were asked to name their friends and play activities, favorite and least-liked school subjects, occupational aspirations, and chores at home. Children generally wanted, asked for, received, and most-liked gender-typical toys. They were less likely to receive requested gender-atypical toys. Children's preferred activities, job aspirations and assigned chores were along gender-typical lines. Girls preferred masculine toys and jobs more than boys preferred feminine ones. With increasing age, both girls and boys increasingly preferred masculine toys and male friends. No gender differences in favorite or least-liked school subjects were found. School subject preference was related to gender-typing of occupational choice for girls but not boys.An earlier version of this paper was presented at the annual meeting of the American Psychological Association, Anaheim, California, 1983.     

The helping process in group therapy: A review and discussion

The essential activity of group therapy consists of members taking an interest in each other by asking questions, showing concern, and conveying understanding. When members have not done this it has often been taken as a sign of resistance. A review of the research on helping suggests that there are four social factors that affect assistance giving in groups: 1) ambiguity-often people fail to give help because they are uncertain about who should give it, what should be done, and how it should be done; 2) often help is not given because of the way in which problems are presented; 3) the social comparisons that individuals make affect help-giving; and 4) there are costs associated with providing assistance. This discussion suggests that leaders can facilitate interaction among group members as teachers who clarify and as indirect helpers who redirect concerns back to group members.     

An exploratory study of videotapes of long-term group psychotherapy of outpatients with major and chronic mental illness

This study explored patterns emerging in videotaped sessions of group psychotherapy with seven outpatients of a large mental health facility. The 22 sessions spanned the 12th to 27th months of the group's existence. Group members had long histories (25–50 years) of symptoms characteristic of schizophrenia. Each session was rated on the Group Environment Scale. One session from a group in its earlier stages was also rated on the same instrument to give some indication of baseline patterns. Analyses of changes across the 15 months were not statistically significant. However, some GES subscales, including Cohesion, Independence, and Self-Discovery, showed relatively high mean levels across the 15-month period. These elevations are discussed as suggesting the codevelopment of orientations that have sometimes been viewed as incompatible and unattainable for schizophrenics. Interpreted clinically, the GES patterns help to elaborate recent findings about the relatively good success of long-term group therapy with such populations. The study, although merely suggestive, illustrates the potential for gleaning solid and clinically useful data from group psychotherapy research.The authors would like to thank Drs. Jill Rierdan, Nina Fieldsteel, Joseph Christy, and an anonymous reviewer for their suggestions, Kendra Bryant for serving as the reliability rater, and Janet Eltinge for her skilled videotaping.     

The desire to lose one's identity

The desire to merge identities with an intimate partner was found to be negatively related to psychoticism but related to other social desires, such as the desire for physical closeness and identifying with the achievements of others.
