Two psychological refractory period (PRP) experiments were conducted to examine overlapping processing in younger and older adults. A shape discrimination task (triangle or rectangle) for Task 1 (T1) and a lexical-decision task (word or nonword) for Task 2 (T2) were used. PRP effects, response time for T2 increasing as stimulus onset synchrony (SOA) decreased, were obtained for both age groups. The effect of word frequency on T2 was smaller at the short SOA than at the long SOA, reflecting slack effects, which were larger for older than younger adults in both experiments. These results suggest that older adults can perform lexical access of T2 in parallel with the processing of T1 at least as efficiently as younger adults. 相似文献

The current study explored the intergenerational transmission of aggression and antisocial behavior by examining mothers' juvenile delinquency, their pregnancies, and its impact on their children's aggressive behavior. The sample consisted of the first 181 biological mothers recruited as part of the Vancouver Longitudinal Study on the Psychosocial Development of Children (British Columbia, Canada). Results indicated that mothers who were juvenile delinquents were more likely to experience social adversity, to use substances during pregnancy and to offend in adulthood. Furthermore, mothers who reported juvenile delinquency had children who were more physically aggressive and had an earlier onset of physical aggression. This pattern of association held when controlling for sociodemographics, social adversities, prenatal substance exposure, and criminal involvement in adulthood. The study findings highlighted the importance of understanding the role and impact of female delinquency and motherhood on the intergenerational transmission of antisocial behavior. 相似文献

The involvement of anger in the psychological adjustment of current war veterans, particularly in conjunction with combat-related posttraumatic stress disorder (PTSD), warrants greater research focus than it has received. The present study concerns a brief anger measure, Dimensions of Anger Reactions (DAR), intended for use in large sample studies and as a screening tool. The concurrent validity, discriminant validity, and incremental validity of the instrument were examined in conjunction with behavioral health data for 3,528 treatment-seeking soldiers who had been in combat in Iraq and Afghanistan. Criterion indices included multiple self-rated measures of psychological distress (including PTSD, depression, and anxiety), functional difficulties (relationships, daily activities, work problems, and substance use), and violence risk. Concurrent validity was established by strong correlations with single anger items on 4 other scales, and discriminant validity was found against anxiety and depression measures. Pertinent to the construct of anger, the DAR was significantly associated with psychosocial functional difficulties and with several indices of harm to self and to others. Hierarchical regression performed on a self/others harm index found incremental validity for the DAR, controlling for age, education, military component, officer rank, combat exposure, PTSD, and depression. The ability to efficiently assess anger in at-risk military populations can provide an indicator of many undesirable behavioral health outcomes.

Between 1998 and 2006, twenty-seven states amended their constitutions to prohibit same sex marriage. The 2008 elections again
saw three states with ballot measures aimed at banning gay marriage. This study examines the determinants of support for those
measures in California and Florida, and includes a similar measure placed on the primary election ballot in California in
2000. Support is measured as the county-wide vote in favor of each gay marriage ban. A number of hypotheses are explored that
examine the urban/rural nature of each county, as well as the political and demographic characteristics of county residents.
It is suggested that states may be best viewed as relatively independent groupings of diverse subcultures, rather than as
homogenous populations with a single political culture. The findings reported here indicate that a host of demographic, political
and religious differences within each state influence residents’ votes on gay marriage bans. 相似文献

This study examines the differential effects of outcome feedback for achievement goal orientations' relationship with effort and achievement. In support of our predictions, learning goal orientation had a positive relationship with task achievement in the absence of outcome feedback and a negative relationship in its presence, while performance goal orientation maintained a positive relationship with achievement regardless of whether outcome feedback was provided. We attribute this to a decrease in task interest when initial task purpose, as determined by personal goal orientation, is incongruent with the subsequent task cues provided by outcome feedback. Predictions regarding task effort and combined goal orientation effects were not supported. Implications for theory and practice are discussed. 相似文献

Next generation sequencing technology is increasingly utilized in oncology with the goal of targeting therapeutics to improve response and reduce side effects. Interpretation of tumor mutations requires sequencing of paired germline DNA, raising questions about incidental germline findings. We describe our experiences as part of a research team implementing a protocol for whole genome sequencing (WGS) of tumors and paired germline DNA known as the Michigan Oncology Sequencing project (MI-ONCOSEQ) that includes options for receiving incidental germline findings. Genetic counselors (GCs) discuss options for return of results with patients during the informed consent process and document family histories. GCs also review germline findings and actively participate in the multi-disciplinary Precision Medicine Tumor Board (PMTB), providing clinical context for interpretation of germline results and making recommendations about disclosure of germline findings. GCs have encountered ethical and counseling challenges with participants, described here. Although GCs have not been traditionally involved in molecular testing of tumors, our experiences with MI-ONCOSEQ demonstrate that GCs have important applicable skills to contribute to multi-disciplinary care teams implementing precision oncology. Broader use of WGS in oncology treatment decision making and American College of Medical Genetics and Genomics (ACMG) recommendations for active interrogation of germline tissue in tumor-normal dyads suggests that GCs will have future opportunities in this area outside of research settings. 相似文献

This study evaluated the effects of self‐monitoring by swimmers to improve their performance and assessed the effects of reactivity to observer presence on their performance. Seven public high school swim team members self‐monitored their behavior on dry erase boards to increase the number of assigned laps completed at practice. Reactivity to observer presence was assessed as a confederate, recorded the number of laps completed during observer absent conditions. The percentage of assigned laps completed increased during the self‐monitoring phases. The self‐monitoring and feedback phase further increased the percentage of assigned laps completed and increased the participants' mean level of reporting accuracy. The effects from the reactivity assessment were mixed across participants. Further research is needed to examine reactivity effects in sport settings. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献
