Studying the Motivated Agent Through Time: Personal Goal Development During the Adult Life Span 下载免费PDF全文
This research examined the rank‐order and mean‐level consistency of personal goals at two periods in the adult life span. Personal goal continuity was considered among a group of young adults (N = 145) who reported their goals three times over a 3‐year period and among a group of midlife adults (N = 163) who specified their goals annually over a 4‐year period. Goals were coded for a series of motive‐based (viz., achievement, affiliation, intimacy, power) and domain‐based (viz., finance, generativity, health, travel) categories. In both samples, we noted a moderate degree of rank‐order consistency across assessment periods. In addition, the majority of goal categories exhibited a high degree of mean‐level consistency. The results of this research suggest that (a) the content of goals exhibits a modest degree of rank‐order consistency and a substantial degree of mean‐level consistency over time, and (b) considering personality continuity and development as manifest via goals represents a viable strategy for personality psychologists. 相似文献

Parents have the opportunity to educate their children to facilitate behaviours and lifestyle habits that may prevent or delay genetic disease, or mitigate predispositions within the family. We sought to determine parents’ understanding of genetic knowledge and heritability. Using a quantitative survey methodology 108 volunteer participants were surveyed from a convenience sample of all parents/caregivers within the waiting room of a general children’s outpatient clinic. Results indicated that average genetic knowledge levels were fairly high, with the majority of participants scoring 70–80 % correct on knowledge-based questions. Further, scores were found to be positively correlated with education, but inversely correlated with self-perceived knowledge. This finding suggests that participants with less experience tended to overestimate their knowledge. We suggest that gaps in knowledge of genetics and heritability could be improved by using educational interventions such as media campaigns, provision of informational brochures, or changes to current high school curriculum which would increase exposure to genetics and heritability for both parents and children. 相似文献

Mechanisms consistent with long-term depression in the perirhinal cortex (PRh) play a fundamental role in object recognition memory; however, whether AMPA receptor endocytosis is involved in distinct phases of recognition memory is not known. To address this question, we used local PRh infusions of the cell membrane-permeable Tat-GluA2(3Y) interference peptide or a scrambled control to block the endocytosis of AMPA receptors during the encoding, consolidation, or retrieval phase of object recognition memory. Tat-GluA2(3Y) infusion before the encoding and consolidation phases did not alter recognition memory. In contrast, Tat-GluA2(3Y) infusion prior to the retrieval phase disrupted object recognition memory. The present results indicate a distinct role for AMPA receptor endocytosis in the retrieval of visual recognition memory. 相似文献

We evaluated 2 3-component multiple-schedule sequences-a response interruption and redirection (RIRD) treatment sequence and a no-interaction control sequence-using a multielement design. With this design, we were able to evaluate the immediate and subsequent effects of RIRD on 2 participants' vocal stereotypy. For both participants, RIRD produced an immediate decrease in vocal stereotypy and did not result in a subsequent increase. 相似文献

Feasibility and Preliminary Outcomes of a School-Based Mindfulness Intervention for Urban Youth 总被引:1,自引:0,他引:1

Youth in underserved, urban communities are at risk for a range of negative outcomes related to stress, including social-emotional
difficulties, behavior problems, and poor academic performance. Mindfulness-based approaches may improve adjustment among
chronically stressed and disadvantaged youth by enhancing self-regulatory capacities. This paper reports findings from a pilot
randomized controlled trial assessing the feasibility, acceptability, and preliminary outcomes of a school-based mindfulness
and yoga intervention. Four urban public schools were randomized to an intervention or wait-list control condition (n = 97 fourth and fifth graders, 60.8% female). It was hypothesized that the 12-week intervention would reduce involuntary
stress responses and improve mental health outcomes and social adjustment. Stress responses, depressive symptoms, and peer
relations were assessed at baseline and post-intervention. Findings suggest the intervention was attractive to students, teachers,
and school administrators and that it had a positive impact on problematic responses to stress including rumination, intrusive
thoughts, and emotional arousal. 相似文献

Activation of the infralimbic region (IL) of the medial prefrontal cortex (mPFC) reduces conditioned fear in a variety of situations, and the IL is thought to play an important role in the extinction of conditioned fear. Here we report a series of experiments using contextual fear conditioning in which the IL is activated with the GABAa antagonist picrotoxin (Ptx) during a single extinction session in the fear context. We investigate the impact of this manipulation on subsequent extinction sessions in which Ptx is no longer present. First, we demonstrate that a single treatment with intra-IL Ptx administered in a conditioned fear context greatly accelerates the rate of extinction on the following days. Importantly, IL-Ptx also enhances extinction to a different fear context than the one in which IL-Ptx was administered. Thus, IL-Ptx primes extinction learning regardless of the fear context in which the IL was initially activated. Second, activation of the IL must occur in conjunction with a fear context in order to enhance extinction; the extinction enhancing effect is not observable if IL-Ptx is administered in a neutral context. Finally, this extinction enhancing effect is specific to the IL for it does not occur if Ptx is injected into the prelimbic region (PL) of the mPFC. The results indicate a novel persisting control of fear induced by activation of the IL and suggest that IL activation induces changes in extinction-related circuitry that prime extinction learning. 相似文献
