GENDER DIFFERENCES AND SIMILARITIES IN SELF-CONCEPT WITHIN EVERYDAY LIFE CONTEXTS

A stereotypic pattern of gender differences has been found in previous self-concept research. Men have tended to rate themselves higher on self- concept measures of giftedness, power, and invulnerability, and women have rated themselves higher on self-concept measures of likability and morality. This study tested the validity of these gender differences for two natural life contexts-family and work-from the perspective of target persons and others in the family and work contexts who knew the target persons well. Overall, the gender stereotypic pattern of self-concept scores was evident in work and family self-ratings and observer-inferred ratings. Gender accounted for 3–7% of the variance of the five self- concept dimensions for which a significant gender difference was found.     

THE WOMEN'S STUDIES EXPERIENCE

The impact of women's studies courses on students'feminist activism and related behaviors was assessed through quantitative and qualitative methods. At pretesting, women's studies students (10 classes: 161 women and 18 men) did not report significantly more activism than nonwomen's studies students taught by women's studies faculty (9 classes: 73 women and 48 men) or nonwomen's studies students taught by nonwomen's studies faculty (12 classes: 107 women and 47 men). At posttesting, women's studies students, relative to the comparison students, reported more activism during the semester of evaluation, stronger intentions to engage in future feminist activism, and more important and more positive course-related influences on their personal lives ( p < .0001).     

Narrative skill and testimonial accuracy in typically developing children and those with intellectual disabilities

Children must describe maltreatment coherently for their testimony to be influential in court. We know little about how well children with intellectual disabilities (CWID) describe their experiences relative to typically developing (TD) children, despite CWID's vulnerability to maltreatment. We investigated children's reports of an experienced event and compared coherence in CWID (mild to moderate impairment: 7–11 years) with TD children matched for mental (4–10 years) or chronological age (7–11 years). All children included important markers of narrative coherence in their reports. Children with lower mental ages, particularly those with an intellectual disability, included fewer markers of narrative coherence in their reports than children with higher mental ages. Individual markers of narrative coherence, particularly recall of content, predicted accuracy of testimony and resistance to suggestion even when disability and mental age were taken into account. These findings highlight the importance of helping children to describe their experiences coherently.     

Exploring and measuring differences in person-thing orientations

Individuals differ in their orientation toward aspects of the environment. Previous work suggests that some individuals orient primarily toward people, whereas others orient toward things. Women generally orient towards people more than men, and men orient towards things more than women. Person-thing orientation is related to occupational choices. This research examined the structure of person-thing orientation using a combination of exploratory and confirmatory factor analyses and structural equation modeling. Analyses suggested that thing orientation and person orientation can be measured (1) with a few items; (2) separately from each other; and (3) person orientation and thing orientation are not necessarily bipolar opposites.     

Toward a Model of Social Influence that Explains Minority Student Integration into the Scientific Community

Students from several ethnic minority groups are underrepresented in the sciences, such that minority students more frequently drop out of the scientific career path than non-minority students. Viewed from a perspective of social influence, this pattern suggests that minority students do not integrate into the scientific community at the same rate as non-minority students. Kelman (1958, 2006) describes a tripartite integration model of social influence (TIMSI) by which a person orients to a social system. To test if this model predicts integration into the scientific community, we conducted analyses of data from a national panel of minority science students. A structural equation model framework showed that self-efficacy (operationalized consistent with Kelman's 'rule-orientation') predicted student intentions to pursue a scientific career. However, when identification as a scientist and internalization of values are added to the model, self-efficacy becomes a poorer predictor of intention. Additional mediation analyses support the conclusion that while having scientific self-efficacy is important, identifying with and endorsing the values of the social system reflect a deeper integration and more durable motivation to persist as a scientist.     

Gender and the Choice of a Science Career: The Impact of Social Support and Possible Selves

This study examined the relationships among perceived social support, beliefs about how one would fare in a science career, and perceptions and choice of a career in science. Participants were 48 men and 33 women from the Midwestern United States who had been identified as gifted in mathematics and science and participated in a high school science enrichment program. They ranged in age from 24 to 28?years old, and the sample was predominantly White (83.3%). Participants completed an online measure approximately 10?years after the program ended examining their sources of support and beliefs about the self as a scientist to see how these variables influence perceptions of a science career and actual career. We expected that the relationship between perceived support from people and current job held would be mediated by participants’ beliefs about their personal life as a scientist in the future. Similarly, we expected that the relationship between a perceived supportive environment and having a science career would be mediated by participants’ beliefs about their career as a scientist in the future. Findings indicated that social support contributed directly to men’s and women’s ability to envision themselves in a future science career, which, in turn, predicted their interest in and motivation for a science career. No significant gender differences were found in the predictors of men’s and women’s perceptions and choice of a science career. Implications for recruitment of students into scientific majors and careers are discussed.     

Social awareness and early self-recognition

Self-recognition by 86 children (14-52months) was assessed using the mirror mark test in two different social contexts. In the classic mirror task condition, only the child was marked prior to mirror exposure (Classic condition). In the social norm condition, the child, experimenter, and accompanying parent were marked prior to the child's mirror exposure (Norm condition). Results indicate that in both conditions children pass the test in comparable proportion, with the same increase as a function of age. However, in the Norm condition, children displayed significantly more hesitation while removing the mark, often touching it without removing it or, if so, promptly putting the mark back onto their forehead. In the Classic condition, only one child showed such hesitation. These results suggest that from the outset, mirror self-recognition can refer to social awareness. This link is interpreted as the trademark of human self-consciousness, a deeply rooted "looking glass" self-awareness.     

Abnormalities in the awareness of action

Optimal motor control relies on internal representations of the actual, desired and predicted states of our limbs and the external world. Only certain components of these internal representations are available to awareness. We suggest that impairments of the components of internal representations might underlie a broad variety of neuropsychiatric symptoms, including the anarchic hand sign, phantom limbs, utilization behaviour and delusions of control.     

Effects of environmental enrichment on rate of contextual processing and discriminative ability in adult rats

The effect of environmental enrichment on conditioned freezing to contextual cues in adult Sprague-Dawley rats was examined. The freezing of both enriched-and standard-reared rats increased with the time spent in the chamber prior to shock. Both groups of rats showed equally low levels of contextual conditioning following a preshock period of 4 s and equally high levels following a 120-s preshock period. However, following a preshock period of 16 s enriched rats displayed more contextual conditioning than standard rats. That is, enriched rats appeared to process contextual information faster than their standard-reared counterparts. Enriched- reared rats also showed a greater ability to discriminate between the conditioning context and a similar but distinctive context. Hence, in addition to forming a representation of the context in memory more rapidly than standard-reared rats, enriched-reared rats also appear to form a more complex representation.     

Effects of 7.5% CO2-Induced Anxiety on Individual Performance During a Group Computer Combat Game

The inhalation of 7.5% CO₂ has been shown to induce cognitive effects similar to anxiety. Sixteen healthy participants (14 male; mean age 25.6 years) inhaled either a mixture of 7.5% CO₂ gas or air while playing a group combat computer game. Participants reported greater feelings of anxiety and fired fewer bullets when inhaling CO₂ compared with air, indicating CO₂-induced anxiety may improve efficiency without task-related decrements. Being able to induce controlled and measured anxiety in group situations by CO₂ inhalation may be a useful technique when evaluating response to stressful situations, such as combat, in simulators or real-life scenarios.
