Wars in Afghanistan and Iraq are associated with more deployments than in previous years. Recent estimates show 1.2 million school children have a parent that is serving in the active military. Family stress increases proportionately to the length of deployment and the perception of danger. In a recent study, twenty percent of children whose parent was being deployed were identified as ??high risk?? for psychosocial disturbances. A deployed parent represents a stressor reflecting ambiguous loss which prompts emotional distress. Cognitive behaviorally based prevention and intervention efforts have shown considerable promise with children experiencing a variety of disorders who do not necessarily have a deployed parent. For instance the Penn Resiliency Program has enjoyed considerable empirical support. It seems quite reasonable that these favorable results would generalize to a population of military children. This paper will briefly review the extant literature on the effects of parental deployment on children??s emotional well-being and then recommend a variety of cognitive behavioral interventions to enhance their psychological welfare.  相似文献

Geriatric researchers and clinicians often have to deal with a lack of valid personality measures for older age groups (e.g., Mroczek, Hurt, & Berman, 1999; Zweig 2008), which hampers a reliable assessment of personality in later life. An age-neutral measurement system is one of the basic conditions for an accurate personality assessment across the lifespan, both longitudinally and cross-sectionally. In the present study, we empirically investigate the age-neutrality of one of the most widely used personality measures (i.e., the NEO PI-R (Costa & McCrae, 1992)), by examining potential Differential Item Functioning (DIF). Overall, results indicate that the vast majority (92.9?% at domain-level and 95?% at facet-level) of the NEO PI-R items was similarly endorsed by younger and older age groups with the same position on the personality trait of interest, corroborating the NEO PI-R??s age neutrality. However, Differential Test Functioning (DTF) analyses revealed large DTF for Extraversion, and facet A6 (Tender-Mindedness). Results are discussed in terms of their implications for using the current format of the NEO PI-R in older aged samples.  相似文献

In the face of the growing prevalence of multiple appeals to sustainable consumption in marketers’ sustainable product communications, we examine the efficacy, in terms of consumer reactions, of adding an extrinsic appeal (e.g., “Purchase this green product to save money!”) to an intrinsic appeal (e.g., “Purchase this green product to save the environment!”) based communication for a sustainable product. Three studies provide support for our basic assertion that, compared to an intrinsic appeal, joint appeals (i.e., an intrinsic and extrinsic appeal together) reduce consumer preference for sustainable products. As well, these studies demonstrate that this adverse effect of joint appeals is based on a lowering of consumers’ attributions of the company's sustainability efforts to intrinsic motives (e.g., to the company's genuine concern for the environment). Finally, not all consumers react adversely to joint appeals; relative to intrinsic appeals, such appeals increase, rather than decrease, the intrinsic attributions and sustainable product preferences for consumers with lower involvement with sustainable consumption.  相似文献

It is well established that glucocorticoid hormones strengthen the consolidation of hippocampus-dependent spatial and contextual memory. The present experiments investigated glucocorticoid effects on the long-term formation of conditioned taste aversion (CTA), an associative learning task that does not depend critically on hippocampal function. Corticosterone (1.0 or 3.0 mg/kg) administered subcutaneously to male Sprague–Dawley rats immediately after the pairing of saccharin consumption with the visceral malaise-inducing agent lithium chloride (LiCl) dose-dependently increased aversion to the saccharin taste on a 96-h retention test trial. In a second experiment, rats received corticosterone either immediately after saccharin consumption or after the LiCl injection, when both stimuli were separated by a 3-h time interval, to investigate whether corticosterone enhances memory of the gustatory or visceral stimulus presentation. Consistent with the finding that the LiCl injection, but not saccharin consumption, increases endogenous corticosterone levels, corticosterone selectively enhanced CTA memory when administered after the LiCl injection. Suppression of this training-induced release of corticosterone with the synthesis-inhibitor metyrapone (35 mg/kg) impaired CTA memory, and was dose-dependently reversed by post-training supplementation of corticosterone. Moreover, direct post-training infusions of corticosterone into the insular cortex or basolateral complex of the amygdala, two brain regions that are critically involved in the acquisition and consolidation of CTA, also enhanced CTA retention, whereas post-training infusions into the dorsal hippocampus were ineffective. These findings provide evidence that glucocorticoid effects on memory consolidation are not limited to hippocampus-dependent spatial/contextual information, but that these hormones also modulate memory consolidation of discrete-cue associative learning via actions in other brain regions.  相似文献

This study examined the development of declarative and procedural memory longitudinally in primary school‐aged children. At present, although there is a general consensus that age‐related improvements during this period can be found for declarative memory, there are conflicting data on the developmental trajectory of the procedural memory system. At Time 1 children aged around 5½ years were presented with measures of declarative and procedural memory. The tasks were then administered 12 months later. Performance on the declarative memory task was found to improve at a faster rate in comparison to the procedural memory task. The findings of the study support the view that multiple memory systems reach functional maturity at different points in development.  相似文献

Youth homelessness is a problem characterized by high levels of vulnerability. The extent to which couch surfing — moving from one temporary housing arrangement to another — is part of youth homelessness is not well understood. Chapin Hall's Voices of Youth Count, a national research initiative, involves a multicomponent approach to studying youth homelessness. This study reports emerging findings regarding couch surfing and homelessness primarily from a national survey of 13,113 adults with youth ages 13–25 in their households or who are themselves ages 18–25. Findings suggest that couch surfing is relatively common, particularly among the older age group. Among households with 13‐ to 17‐year‐olds and 18‐ to 25‐year‐olds, 4.0% and 20.5%, respectively, reported that any of them had couch surfed in the last 12 months. There are notable social, economic, and educational differences, on average, between youth reporting homelessness and those reporting only couch surfing. However, most youth who report experiencing homelessness also report couch surfing, and these youth who experience both circumstances present high levels of socioeconomic vulnerability. Couch surfing encompasses a range of experiences, some of which likely include need for services. Interviews currently in the field, and expanded analysis of data, will contribute more nuanced policy insights.  相似文献

This study evaluated the use of written checklists and task analyses as self-administered prompts to teach home accident prevention skills to 4 adults with brain injuries. Subsequent to baseline, participants used written checklists that identified potential in-home hazards but did not prompt behaviors necessary for hazard remediation. Written individualized task analyses, incorporating specific behavioral steps for correcting hazards that participants had failed to remediate during the checklist phase, were used to prompt appropriate responding when necessary. These were subsequently faded to transfer stimulus control to the natural conditions. A multiple probe technique across participants and settings was used. Results indicated that the checklist alone was sufficient to increase appropriate responses to many of the potential hazards. Individualized task analyses, when needed, resulted in appropriate remediation of all potential hazards. Generalization to untrained potential hazards occurred to some degree for all participants. Follow-up results showed that most skills trained were maintained over a 1-month period.  相似文献

Present research and legislation regarding mainstreaming autistic children into normal classrooms have raised the importance of studying whether autistic children can benefit from observing normal peer models. The present investigation systematically assessed whether autistic children's learning of discrimination tasks could be improved if they observed normal children perform the tasks correctly. In the context of a multiple baseline design, four autistic children worked on five discrimination tasks that their teachers reported were posing difficulty. Throughout the baseline condition the children evidenced very low levels of correct responding on all five tasks. In the subsequent treatment condition, when normal peers modeled correct responses, the autistic children's correct responding increased dramatically. In each case, the peer modeling procedure produced rapid achievement of the acquisition criterion which was maintained after the peer models were removed. These results are discussed in relation to issues concerning observational learning and in relation to the implications for mainstreaming autistic children into normal classrooms.  相似文献

A same-different matching task was used to investigate how subjects perceived a dichotic pair of pure tones. Pairs of stimulus tones in four frequency ranges (center frequencies of 400–1,700 Hz), with separations between 40 and 400 Hzt were tested. Five types of test tones were matched to the stimulus pair: the stimulus pair presented again (control) or crossed over (same tones, different ears), the geometric mean of the two tones, or a binaural tone of the low or high tone of the pair. In the lowest frequency range and the highest with maximum separation, the crossed-over test tones were perceived as different from the same stimulus tones. A bias for perceiving the higher tone of a pair was evident in the frequency ranges with separations of 40-200 Hz. In the lowest frequency range, the bias was for perceiving the higher tone in the right ear. This restricted ear advantage in the perception of pure tones was not significantly related to the right-ear advantage in dichotic word monitoring.  相似文献
