We examined a new structured interview of parent?Cchild conflict that assesses parent and child perceptions of behavioral conflict about daily life topics (e.g., doing chores, homework), and whether discrepancies exist on beliefs about these topics. In a sample of 100 parents and children ages 10 to 17?years (M?=?13.5?years, 52 males, 57?% African-American), informants could reliably distinguish between perceived behavioral conflicts and perceived discrepant beliefs about topics. These scores were also significantly related to questionnaire reports of parent?Cchild conflict. Parent and child questionnaire reports did not significantly differ, yet on the structured interview, parents reported significantly greater levels of perceived conflict and discrepant beliefs relative to child reports. Additionally, structured interview reports of conflict demonstrated incremental validity by relating to child self-reports of delinquent behaviors, when accounting for questionnaire conflict reports. The findings have implications for increasing understanding of the links between parent?Cchild conflict and psychosocial outcomes. 相似文献

We investigated working memory updating performance in younger and older adults before, during, and after 100-day practice. Performance to presentation time (PT) relation was fitted to a negatively accelerated logistic function. Relative to younger adults, older adults showed lower asymptotes at pretest and posttest, and shallower slopes at pretest. Older adults practicing the task with fast PT gained less than older adults practicing the task with slow PT, probably reflecting the persistent use of a selective strategy throughout the 100-day practice period in the fast PT group. These results have implications for designing and evaluating age-comparative working memory training programs. 相似文献

Purpose
This paper aims to develop and apply a multi-attribute utility analysis model (MAU) to assess the benefits of HRM interventions as an alternative to the traditional utility analysis method.Design/Methodology/Approach
MAU adopts a cost-benefit multi-variant approach to assess HRM efficiency using a non-monetary metric. The study employs a quasi-experimental design to examine the training effects on job performance, comparing pre- and post-intervention measures mostly from sub-groups of random sample of 367 trainees.Findings
We showed that is feasible to adopt a multi-attribute evaluation approach in HRM area by adapting the MAUT technique. Our formal MAU model also demonstrated that it is possible to adopt a broader and more global evaluation approach than other more ??myopic?? models such as traditional UA models. Results after applying our MAU model in a real organization indicated considerable utility from training employees.Implications
The commitment and involvement of the organization in the evaluation project seem to suggest an interest in comprehensive evaluative models for HRM such as MAU. Because the amount of information that MAU model entails, it may be also used as a strategic instrument for continuous improving of HR interventions and as a mechanism to analyze the evaluation policy of different stakeholders groups.Originality/Value
We provide a theoretical development of a MAU model and offer its first empirical application in a firm to calculate the utility of training. This contributes to utility analysis research and provides a guide for practitioners evaluating HRM benefits. 相似文献984.
Objective: Several longitudinal studies had shown that early deprivation and institutionalization during the first six months of life affects the emotional, cognitive, social and neurophysiologic development. Nevertheless, our understanding of possible similar effects of delayed institutionalization, in preschool-age remains unclear to this day. The goal of this study is to evaluate the cognitive performance of institutionalized children with history of preschool-age physical abandonment. Method: 18 male institutionalized children with history of abandonment during the preschool-age (2-5 years old) and comparison group matched by age, handedness, gender, educational and socioeconomic level were tested on multiple tasks of attention, memory and executive functions. Results: We found a cognitive impairment in the institutionalized children in several measures of attention, memory and executive functions. This is the first report of cognitive impairment related to late abandonment and institutionalization effects (after 2 years old), extending the already known effects on early institutionalization. Conclusions: This preliminary study suggests that environmental factors including abandonment and institutional care, can affect not only the infancy period, but also the preschool period providing new insights into our understanding of neurocognitive development. 相似文献

Abstract: The concept of a situation underlying the debate between moral situationists and dispositionists conceals various underexplored complexities. Some of those issues have been engaged recently in the so‐called psychology of situations, but they have been slow to receive attention in mainstream philosophy. I invoke various distinctions among situations, and show how situationists have selectively chosen certain types of situations that, for conceptual reasons, skew the argument in their favour. I introduce the concept of a ‘virtue‐calibrated situation’, and argue that if the person–situation debate is to move forward in philosophy as it has in psychology, it must focus on such situations. I bring to bear evidence from analytic and continental philosophy, as well as from social and personality psychology. 相似文献

Although a large body of research has examined the negative outcomes that occur when Latina adolescents engage in sexual activity, relatively little research explores the determinants that may contribute to these behaviors. In the current study, an ecological community psychological approach was used to examine the impact that substance use, sexual self-efficacy, parental communication, normative peer pressure, acculturation, educational aspirations, grades, and gang activity have on adolescent sexual behavior. The sample consisted of 217 participants (mean age of 14.6) who self-identified as Latina from the greater Los Angeles metropolitan area of California in the United States. The results indicate that about a third of the sample had engaged in one or more sexual behaviors. Overall, greater usage of substances was associated with greater numbers of sexual behaviors. Girls who reported engaging in two or more sexual behaviors reported more frequent marijuana and alcohol use. The girls who reported high sexual self-efficacy engaged in few to no sexual behaviors. Additionally, parental communication, normative peer pressure, acculturation, and educational aspirations were unrelated to their sexual behavior. However, the majority of girls who reported receiving good grades also reported no sexual activity. Moreover, girls who reported no sexual behavior also reported no gang activity. The results indicate that a multi-level approach to examining the psycho-social determinants of sexual activity in Latina girls provides a more comprehensive picture of their sexual decision making. 相似文献

Social stress affects cognitive processes in general, and memory performance in particular. However, the direction of these effects has not been clearly established, as it depends on several factors. Our aim was to determine the impact of the hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) reactivity to psychosocial stress on short-term non-declarative memory and declarative memory performance. Fifty-two young participants (18 men, 34 women) were subjected to the Trier Social Stress Task (TSST) and a control condition in a crossover design. Implicit memory was assessed by a priming test, and explicit memory was assessed by the Rey Auditory Verbal Learning Test (RAVLT). The TSST provoked greater salivary cortisol and salivary alpha-amylase (sAA) responses than the control task. Men had a higher cortisol response to stress than women, but no sex differences were found for sAA release. Stress was associated with an enhancement of priming but did not affect declarative memory. Additionally, the enhancement on the priming test was higher in those whose sAA levels increased more in response to stress (r(48)?=?0.339, p?=?0.018). Our results confirm an effect of acute stress on priming, and that this effect is related to SNS activity. In addition, they suggest a different relationship between stress biomarkers and the different memory systems. 相似文献

Previous work on social support and stress tolerance using laboratory-based cardiovascular stress response paradigms has suggested that perceived social support may be effective in building resilience in recipients. However, such paradigms are often socially de-contextualized insofar as they fail to take account of the social aspects of stress itself. Using 90 healthy college women, the present study sought to examine the association between self-reported perceived social support and cardiovascular stress tolerance. Participants underwent two consecutive exposures to a mental arithmetic task. On second exposure to the stressor, participants completed the task under either social threat or control conditions. Social threat was manipulated using socially salient instructions, to create a high social context. Adaptation to stress was established in terms of comparisons between cardiovascular responses to successive exposures. Results showed that cardiovascular responses tended to habituate across time, with perceived social support associated with the degree of habituation, but only under certain contextual conditions; high perceived support was associated with effective habituation under control conditions only. This response pattern is consistent with the view that high perceived social support buffers against stress in healthful ways, but only in asocial contexts. 相似文献

Post-acquisition release of glutamate and norepinephrine in the amygdala is involved in taste-aversion memory consolidation 总被引:1,自引:0,他引:1

Amygdala activity mediates the acquisition and consolidation of emotional experiences; we have recently shown that post-acquisition reactivation of this structure is necessary for the long-term storage of conditioned taste aversion (CTA). However, the specific neurotransmitters involved in such reactivation are not known. The aim of the present study was to investigate extracellular changes of glutamate, norepinephrine, and dopamine within the rat amygdala using in vivo microdialysis during the acquisition and 1-h post-acquisition of CTA paradigm. Microdialysis monitoring showed a significant norepinephrine increase related to novel taste exposure and a glutamate increase after gastric malaise induction by i.p. LiCl administration. Interestingly, we found a spontaneous concomitant increase of glutamate and norepinephrine, but not dopamine, 45 min after conditioning, suggesting the presence of aversive learning-dependent post-acquisition signals in the amygdala. These signals seem to be involved in CTA consolidation process, since post-trial blockade of N-methyl-D-aspartate or β-adrenergic receptors impaired long- but not short-term memory. These data suggest that CTA long-term storage involves post-acquisition release of glutamate and norepinephrine in the amygdala. 相似文献

The community mental health (CMH) system provides treatment for behavioral and psychiatric problems in children with autism spectrum disorders (ASD). Although parent stakeholder perspectives are important to improving care, these perspectives have not been systematically examined for this population in the CMH sector. Twenty-one semi-structured qualitative interviews were conducted with parents of children with ASD who received services in CMH clinics. Themes related to child clinical histories, service access and experiences with the CMH system revealed a specific trajectory of service need identification, obtaining a diagnosis, and experience with services. Each trajectory stage was marked by high parent stress. Results provide information about the characteristics of children with ASD served in community mental health clinics and direction for targeted improvement efforts. 相似文献
