Value priorities in American and British female and male university students

Value priorities were analyzed as they relate to nationality (American vs. British) and gender in a study involving 207 university students from the 2 countries. Participants responded anonymously to S. H. Schwartz's Value Survey (1992, 1994), consisting of various individualistic and collectivistic values. American students assigned greater importance to the individualistic values of achievement, hedonism, self-direction, and stimulation than British students did; students from the 2 countries assigned equal importance to the power value type. Compared with men, women from both countries assigned greater value priorities to the collectivistic values of benevolence, universalism, security, and subordination of self to others. Women and men, however, did not differ on the individualistic values, and, in fact, women placed greater importance on achievement than men did. The results for the individualistic values are discussed primarily within the context of major changes in the career and work opportunities afforded women by society in the past 30 years.     

Comparison of impulsive and premeditated perpetrators of intimate partner violence

Violence occurs in four to five million intimate relationships each year in the United States. Past research has investigated the concept of batterer subtypes based on the nature of the violent behavior. To extend this research, the present study used the Impulsive/Premeditated Aggression Scale (IPAS) along with a battery of relevant self-report measures in a sample of men (N = 113) convicted of domestic violence and court ordered into an intervention program. Batterers whose violence was classified as premeditated scored higher on psychopathic traits and a measure of treatment rejection. Batterers whose violence was classified as impulsive in nature reported a wider range of serious psychopathology. It is suggested that the use of a bimodal classification (Impulsive/Premeditated) in batterers may have significant clinical and legal policy implications.

Word learning in deaf children with cochlear implants: effects of early auditory experience

Word-learning skills were tested in normal-hearing 12- to 40-month-olds and in deaf 22- to 40-month-olds 12 to 18 months after cochlear implantation. Using the Intermodal Preferential Looking Paradigm (IPLP), children were tested for their ability to learn two novel-word/novel-object pairings. Normal-hearing children demonstrated learning on this task at approximately 18 months of age and older. For deaf children, performance on this task was significantly correlated with early auditory experience: Children whose cochlear implants were switched on by 14 months of age or who had relatively more hearing before implantation demonstrated learning in this task, but later implanted profoundly deaf children did not. Performance on this task also correlated with later measures of vocabulary size. Taken together, these findings suggest that early auditory experience facilitates word learning and that the IPLP may be useful for identifying children who may be at high risk for poor vocabulary development.     

Neural correlates of socioeconomic status in the developing human brain

Socioeconomic disparities in childhood are associated with remarkable differences in cognitive and socio-emotional development during a time when dramatic changes are occurring in the brain. Yet, the neurobiological pathways through which socioeconomic status (SES) shapes development remain poorly understood. Behavioral evidence suggests that language, memory, social-emotional processing, and cognitive control exhibit relatively large differences across SES. Here we investigated whether volumetric differences could be observed across SES in several neural regions that support these skills. In a sample of 60 socioeconomically diverse children, highly significant SES differences in regional brain volume were observed in the hippocampus and the amygdala. In addition, SES × age interactions were observed in the left superior temporal gyrus and left inferior frontal gyrus, suggesting increasing SES differences with age in these regions. These results were not explained by differences in gender, race or IQ. Likely mechanisms include differences in the home linguistic environment and exposure to stress, which may serve as targets for intervention at a time of high neural plasticity.     

Heterogeneity in Verbal Memory: A Marker of Preclinical Alzheimer's Disease?

ABSTRACT

Demonstrations of memory changes in those at risk for Alzheimer's disease by the presence of the APOE e4 allele have been inconsistent to date. The present study went beyond traditional analyses of central tendency (i.e., group differences on mean test scores) and also conducted distribution analyses to search for subtle cognitive differences in subgroups of normal-functioning elderly persons with the APOE e4 genotype. The results of the study revealed that (a) the e4 and non-e4 groups failed to differ in terms of their mean scores on tests of memory and verbal skills; and (b) relative to the non-e4 group, the e4 subjects had significantly greater heterogeneity of variance on the memory measures but not on fundamental verbal skills. Logistic regression analyses indicated that the discrepancy in scores on the memory measures was a significant predictor of genotype group membership (82% correct classification rate). Implications of these findings for the detection of a preclinical phase of AD are discussed.     

Development of the Multidimensional Peer Victimization Scale–Revised (MPVS-R) and the Multidimensional Peer Bullying Scale (MPVS-RB)

Peer victimization is a frequent occurrence for many adolescents; however, some of the psychometric properties of self-report scales assessing these experiences remain unclear. Furthermore, with an increase in access to technology, electronic aggression should also be considered. The authors examined the psychometric properties of the Multidimensional Peer Victimization Scale (MPVS; Mynard & Joseph, 2000), and developed versions to include the assessment of electronic aggression according to whether the adolescent was the target or perpetrator of peer victimization. A total of 371 (191 girls and 180 boys; M_age = 13 years 4 months, SD_age = 1 year 2 months) adolescents in the United Kingdom completed the MPVS including five newly developed items assessing electronic aggression, a version of the MPVS designed to assess victimization perpetration, and a measure of self-esteem. Confirmatory factor analyses yielded a five-factor structure comprising: Physical, social manipulation, verbal, attacks on property, and electronic for both scales. Convergent validity was established through negative associations between the victimization scales and self-esteem. Sex differences also emerged. One revised scale and one new scale are subsequently proposed: The MPVS–Revised and the Multidimensional Peer Bullying Scale.

Fear Associated With September 11 Television Coverage in Oklahoma City Bombing Survivors

This study explored television viewing of the September 11 attacks in 99 survivors of the Oklahoma City bombing and examined the relationships of event-related television viewing with concerns about safety and danger in survivors with and without bombing-related posttraumatic stress disorder. The number of hours of viewing September 11 television coverage was related to worry about personal and family danger and to increased checking on loved ones but not to September 11–related posttraumatic responses. Some bombing survivors discontinued September 11 media contact due to fear. The findings suggest the importance of monitoring television viewing in survivors of prior incidents.
