Gender and Group Process: A Developmental Perspective

Until recently, the study of gender development has focused mainly on sex typing as an attribute of the individual. Although this perspective continues to be enlightening, recent work has focused increasingly on children's tendency to congregate in same-sex groups. This self-segregation of the two sexes implies that much of childhood gender enactment occurs in the context of same-sex dyads or larger groups. There are emergent properties of such groups, so that certain sex-distinctive qualities occur at the level of the group rather than at the level of the individual. There is increasing research interest in the distinctive nature of the group structures, activities, and interactions that typify all-male as compared with all-female groups, and in the socialization that occurs within these groups. Next steps in research will surely call for the integration of the individual and group perspectives.     

Preliminary exploration of secondhand smoke exposure in youth with Sickle Cell Disease: biochemical verification,pulmonary functioning,and health care utilization

Exposure to secondhand smoke (SHSe) can compound an already challenging set of health problems for youth with Sickle Cell Disease (SCD). Exposure to electronic cigarettes may also impact SCD symptomology and respiratory functioning. This study built on these previous findings by a) utilizing two objective measures of SHSe, salivary cotinine and exhaled carbon monoxide and b) examining the association of SHSe with emergency department utilization, physician-reported sickle cell crises, and pulmonary functioning. Caregivers (N = 31 dyads; M_age = 37.6 years; SD = 8.5 years) of youth with SCD (M_age = 9.0 years; SD = 4.5 years) completed self-report measures of tobacco/nicotine use. Youth provided a saliva sample to assess cotinine levels, and performed pulmonary function tests. Dyads provided breath samples for measurement of eCO. A chart review was conducted to obtain medical history and utilization. Majority of youth (88%) were exposed to SHS via salivary cotinine. Interestingly, no significant associations were observed between youth cotinine levels and emergency department utilization, physician-reported sickle cell crises, or pulmonary functioning. Present findings indicate a need to assess for SHSe using objective assessment measures. Future research should investigate which specific factors contribute to increase SHSe/SHVe in youth with SCD.     

Differential constraints on the working memory and reading abilities of individuals with learning difficulties and typically developing children

This study examined the factors that constrain the working memory span performance and reading ability of individuals with generalized learning difficulties. In the study, 50 individuals with learning difficulties (LD) and 50 typically developing children (TD) matched for reading age completed two working memory span tasks. Participants also completed independent measures of the processing and storage operations involved in each working memory span task and Raven's Coloured Progressive Matrices. The results showed that despite an equivalent level of working memory span, the relative importance of the constraints on working memory differed between the groups. In addition, working memory span was not closely related to word recognition or sentence comprehension performance in the LD group. These results suggest that the working memory span performance of LD and TD individuals may reflect different working memory limitations and that individuals with generalized learning difficulties may approach cognitive tasks in a qualitatively different way from that of typically developing individuals.     

Test-retest reliability and construct validity of Contour Drawing Rating Scale scores in a sample of early adolescent girls

Test–retest and construct validity of Contour Drawing Rating Scale (CDRS) scores were examined in 1056 Grades 7 and 8 girls. Questionnaires were completed four times, including retests at 2, 6 and 14 weeks. Test–retest reliability for current size, ideal size and current–ideal discrepancy mostly exceeded 0.70 (0.65–0.87, for the full sample, with higher rs for shorter retest periods). Ideal and current size ratings increased slightly over time. High correlations between perceived current figure and measured body mass index; moderate rs between current–ideal discrepancy and body dissatisfaction and restrained eating; and very low or no significant correlations with social desirability supported construct validity in this group. The study supported the use of the CDRS in early adolescent girls.     

Learning to control brain activity: a review of the production and control of EEG components for driving brain-computer interface (BCI) systems

Brain-computer interface (BCI) technology relies on the ability of individuals to voluntarily and reliably produce changes in their electroencephalographic (EEG) activity. The present paper reviews research on cognitive tasks and other methods of generating and controlling specific changes in EEG activity that can be used to drive BCI systems. To date, motor imagery has been the most commonly used task. This paper explores the possibility that other cognitive tasks, including those used in imaging studies, may prove to be more effective. Other factors which influence performance are also considered in relation to selection of tasks, as well as training of subjects.     

Managing group process in nonprocess groups: Working with the theme-centered psychoeducational group

While there has been a recent proliferation of groups for consultative and psychoeducational purposes, little has been written about using the group process in these nonprocess groups. This paper investigates the management of various group processes in a group whose contracted focus is teaching stress management skills. Distinctions are made between psychotherapeutic and theme-centered psychoeducational process management. Many group processes can be predicted given the group's normal developmental stages, while other ongoing group processes arise spontaneously. A working dialogue between the presented content and the emerging process is necessary in order for psychoeducation to be personalized and most fully assimilated. A clinical vignette follows the evolution of a stress management group conducted for high-level executives who have been identified as manifesting Type-A behaviors. For each session, the format and material content are briefly outlined, the emerging group process is described, and the clinical interventions involved in the process management are discussed.     

Resource utilization in mixed-sex dyads: The influence of adult presence and task type

This study explores the effects of context on cross-sex dominance. An emerging finding in the sex differences literature is that boys are often more successful than girls at influencing members of the other gender. As a result, boys tend to get more than their share of a scarce resource in mixed-sex situations. Because the presence of adults inhibits just those strategies that boys use successfully when dominating girls, we hypothesize that the presence of an adult will reduce or eliminate the sex difference in access to a scarce resource. This should be particularly true for tasks in which boys' strategies are most likely to be effective. To test this hypothesis, dominance (as evidenced by asymmetry in gaining access to a scarce resource) was measured while 48 boy-girl pairs, ranging in age from 42 to 60 months, negotiated turn taking at a movie viewer in either the presence or absence of an adult (adult location factor) in a situation that either did or did not require the cooperation of the second child in order to see cartoons (task type factor). For the cooperative task, neither sex significantly dominated the other in either the presence or absence of the adult. In contrast, for the competitive task, boys dominated in the absence of the adult. When the adult was present, however, boys and girls shared more equally. An examination of the strategies children used in the competitive task indicated that boys were inhibited in the adult's presence, dropping their rate of demands and giving girls longer turns. Implications for gender segregation and for sex differences in seeking proximity to adults are discussed.Portions of this paper were presented at the biennial meeting of the Society for Research in Child Development in Baltimore, Maryland, April 1987.

An evaluation of a person-centred gestalt group using the semantic differential

This study assessed the types of attitude changes that occurred among counselling students of a US university who were involved in a person-centred gestalt training group. A semantic differential was used to evaluate the effects of the group. The results showed that the members rated the potency scales of the semantic differential concepts, gestalt therapy, love and future, higher because they participated in the group.     

Abstraction and its Limits: Finding Space For Novel Explanation

Several modern accounts of explanation acknowledge the importance of abstraction and idealization for our explanatory practice. However, once we allow a role for abstraction, questions remain. I ask whether the relation between explanations at different theoretical levels should be thought of wholly in terms of abstraction, and argue that changes of the quantities in terms of which we describe a system can lead to novel explanations that are not merely abstractions of some more detailed picture. I use the example of phase transitions as described by statistical mechanics and thermodynamics to illustrate this, and to demonstrate some details of the relationship between abstraction, idealization, and novel explanation.
