Cognitive development following early brain injury: evidence for neural adaptation

Over the past few decades a large body of work from developmental neurobiology has shown that mammalian brain development is the product of dynamic and adaptive processes operating within highly constrained, but continually changing, biological and environmental contexts. The recent study of children with prenatal focal brain injury supports this dynamic view of development for humans. Children's injuries often affect substantial portions of one cerebral hemisphere, resulting in damage that would compromise cognitive ability in adults. However, longitudinal behavioral studies of this population have revealed only mild deficits. It is suggested here that children's capacity for adaptation reflects normal developmental processes operating against a backdrop of serious neural perturbation. Data from three behavioral domains--linguistics, spatial cognition and affective development--illustrate this complex profile of change.

Preschool Children's Emotional Expressions with Peers: The Roles of Gender and Emotion Socialization

This study examined whether mothers and fathers reported using different emotion socialization strategies and whether these differences were related to preschoolers' gender and emotional expressiveness during peer play. Ninety percent of the children were Caucasian, 6% were Asian-American, and 4% were Mexican-American. The positive expressive behavior of 82 preschoolers participating in two conflict eliciting situations with two same gender peers were coded. The scores for the two sessions were averaged. All of the mothers and 63 of the fathers were administered three emotion socialization questionnaires. Results revealed that girls expressed more positive emotion than boys. In addition, mothers and fathers also reported using different emotion socialization practices and, in some cases, this was dependent upon their child's gender. The findings also showed that mothers' and fathers' reports of emotion socialization practices were differentially related to children's emotionally expressive behavior during peer play. In addition, fathers' emotion socialization practices accounted for unique variance in children's emotionally expressive behavior over and above that explained by the maternal emotion socialization variables. These findings highlight the importance of mothers' and fathers' emotion socialization practices for preschoolers' emotional competence in emotionally challenging situations with peers.     

The impact of sex,achievement domain,and conceptual orientation on causal attributions

Sex differences in achievement domain and achievement orientation were examined to better understand women's achievement. College students (84 women, 59 men) were asked to write brief accounts of a past success and a past failure and to provide causal attributions for each. More women recalled affiliative-process events, and proportionally more men recalled mastery-impact events. The relationship of topic domain and conceptual orientation to causal attributions was apparent only for accounts of failure. Topic domain and conceptual orientation interacted with sex to further influence stability attributions. When women conceptualized failure as a process, they emphasized attributions to effort and luck, while men accounted for the process failure by ability and task. When the failure was conceptualized in terms of final impact, the sex pattern of attributions was reversed.     

Burnout in Health Care: The Role of the Five Factors of Personality

Job burnout continues to plague organizations and individuals, resulting in costly consequences. In examining the antecedents to job burnout, prior research has primarily focused on role stressors present in the job environment. with little attention given to individual characteristics. The purpose of this field study was to examine the extent to which dimensions of an individual's personality have differential efects on the 3 components of burnout (emotional exhaustion, depersonalization. and diminished personal accomplishment) among nurses working in a hospital. After controlling for several demographic variables and 3 role stressors, findings indicate that specific dimensions of personality do significantly and differentially impact the experience of the 3 components of burnout.     

Sex Role and Attitudinal Correlates of Desired Family Size

A survey conducted in 1971 with college students as respondents tested the hypothesis that persons approving of a relatively equivalent pattern of sex roles desire to have smaller families than do persons approving of less equivalent sex roles. Though the hypothesis was confirmed for the number of children that Ss desired to procreate, approval of sex role equivalence appeared to be only one component of a more general pattern in which Ss who desired to procreate fewer children were nontraditional in their attitudes. Thus, to the extent that Ss approved of equivalent sex roles, favored Women's Liberation, opposed conservatism, favored liberalism, and considered themselves nonreligious, they tended to have smaller family size goals for biological parenthood. However, the role and attitudinal predictors related less strongly to the total number of children desired (i.e., the sum total of the number of children desired as a biological parent plus the number of adoptions desired).     

Memory for Duration: Role of Hippocampus and Medial Prefrontal Cortex

In this task rats had to learn that a three-dimensional object stimulus (a rectangle) that was visible for 2 s would result in a positive (go) reinforcement for one object (a ball) and no reinforcement (no go) for a different object (a bottle). However, if the rectangle stimulus was visible for 8 s then there would be no reinforcement for the ball (no go), but a reinforcement for the bottle (go). After rats learned this conditional discrimination by responding differentially in terms of latency to approach the object, they received large (dorsal and ventral) lesions of the hippocampus, lesions of the medial prefrontal cortex (anterior cingulate and precentral cortex), lesions of the cortex dorsal to the dorsal hippocampus, or served as sham-operated controls. Following recovery from surgery they were retested. The results indicate that there were major impairments following hippocampal lesions, in contrast to cortical control and medial prefrontal cortex lesions, as indicated by smaller latency differences between positive and negative trials on postsurgery tests. In order to ensure that the deficits observed with hippocampal lesions were not due to a discrimination problem, new rats were trained in an object (gray cylinder) duration discrimination task. In this go/no go procedure, the rats were reinforced for a 2-s exposure (duration) of the gray cylinder, but not a 10-s duration, or vice versa. The results indicate that after hippocampal lesions, there was an initial deficit followed by complete recovery. There were no significant changes for the medial prefrontal, cortical control, or sham-operated animals. It appears that the hippocampus, but not the medial prefrontal cortex, is actively involved in representing in short-term memory temporal attribute information based on the use of markers for the beginning and end of the presence (duration) of a stimulus (object).     

Continuity in Emotion Knowledge from Preschool to Middle-Childhood and Relation to Emotion Socialization

This longitudinal study examined the preschool correlates of middle school children's knowledge of emotional display rules. Participants included 50 children (29 girls) who were seen at preschoolage and again 4 years later. A total of 91% of the children were Caucasian, 4.5% were Mexican American, and 4.5% were Asian American. During the preschool period, measures included children's knowledge of facial expressions, knowledge of emotion-eliciting situations, and emotional role-taking ability. In addition, the rate at which their mothers explained the causes of emotions was assessed. Four years later, the children's knowledge of emotional display rules was assessed. The display rule measures included expression regulation knowledge (i.e., whether the children altered the facial expression relative to the internal feeling without providing a motive), self-protective display rules, and prosocial display rules. Results revealed that preschoolers' situation knowledge was a negative predictor of expression regulation knowledge and that emotional role-taking was inversely related to knowledge of self-protective display rules. The results also demonstrated that the rate at which mothers' explained emotions to their children as preschoolers was positively associated with expression regulation knowledge and knowledge of prosocial display rules.     

The influence of gender on occupational aspirations of kindergarten children

By updating and extending previous research on the effect of gender role socialization on occupational choices of children, this research found very sexstereotypical occupational preferences in a sample of 540 kindergarten children. The girls in the study selected occupations that averaged 87% female and the boys selected occupations averaging 84% male. The boys perceived a significantly wider range of vocational options than the girls. In a reversal condition, children were asked to pretend to be of the opposite sex. Most of the children selected occupations with sex ratios favoring their pretended sex; girls were slightly more stereotypic than boys. An unanticipated finding was the extremeness of reactions of the boys to the suggestion that they pretend to be girls. It is argued that current sex-role socialization fails to recognize the realities of the expanding participation of women in the paid labor force.     

Obituary: Gillian O. Howie, 1965–2013

The present special issue of Sophia on ‘feminist philosophy of religion’ is dedicated to Gillian O. Howie who died in 2013. This essay is a short obituary touching on Howie’s philosophical and personal legacy. The intention is to give a brief overview of Howie as a courageous woman with boundless intellectual curiosity and passionate commitments to feminist activities; these include writing and living her philosophical vision for creating a just society with collective political action. Howie inspired both women and men in philosophy—especially, but not only, feminist philosophers of religion—with her work on the critical role of sexual difference in life today.
