Research suggests that an overgeneral autobiographical memory style (i.e., retrieval of general memories when instructed to retrieve a specific episodic memory) represents a vulnerability marker for depression. Although adolescence is a period of high risk for the emergence of depression, little research has investigated the associations among overgeneral memory, psychopathology, and risk factors longitudinally in a community sample in this age group. We, therefore, investigated overgeneral memory, psychopathology (depression and anxiety), and rumination (an established risk factor for psychopathology) longitudinally in 269 typically-developing youth (125 females, 144 males) across 3 annual assessment points. We sought to determine whether 1) overgeneral memory would predict psychopathology across the entire sample, and 2) whether associations would vary as a function of longitudinal rumination growth. Across the entire sample, overgeneral memory did not predict psychopathology. For youth who reported elevated, and increasing, patterns of rumination over time, transient relationships between overgeneral memory and subsequent increases in anxiety were found. We conclude that overgeneral memory may represent a vulnerability marker for adverse psychological outcomes only for youth at risk for psychopathology. 相似文献

Stress regulation during pregnancy is considered to be connected to the timing of labour initiation. Although increasing knowledge is emerging on the regulation of parturition, there is currently no way to predict the start of spontaneous labour in women. The main aim of this study was to assess pain threshold and the sympathetic nervous system response to cold pain in relation to the onset of labour in healthy pregnant women. Ninety-three pregnant women were recruited and assessed for skin conductance (SC) activity during a cold pressor test in gestational week 38. Pain threshold and cold endurance were also measured and the results were compared with data obtained from hospital records. Seventy-four women had a spontaneous labour onset and a valid SC measurement. SC activity during the cold pressor test decreased significantly with the number of days left to spontaneous parturition. This may indicate a gradual decrease in sympathetic autonomic nervous system reactivity even during the last weeks of pregnancy. Measuring SC activity during mild stress provocation is a rapid and non-invasive means to study variation in sympathetic reactivity during pregnancy, and may be useful in research on stress regulation in pregnancy and its relation to labour initiation. 相似文献

BDNF regulates components of cognitive processes and has been implicated in psychiatric disorders. Here we report that genetic overexpression of the BDNF mature isoform (BDNF-tg) in female mice impaired working memory functions while sparing components of fear conditioning. BDNF-tg mice also displayed reduced breeding efficiency, higher anxiety-like scores, high self-grooming, impaired prepulse inhibition, and higher susceptibility to seizures when placed in a new empty cage, as compared with wild-type (WT) littermate controls. Control measures of general health, locomotor activity, motor coordination, depression-related behaviors, and sociability did not differ between genotypes. The present findings, indicating detrimental effects of life-long increased BDNF in mice, may inform human studies evaluating the role of BDNF functional genetic variations on cognitive abilities and vulnerability to psychiatric disorders. 相似文献

A favorable product country of origin (e.g., an automobile made in Germany) is often considered an asset by marketers. Yet a challenge in today's competitive environment is how marketers of products from less favorably regarded countries can counter negative country of origin perceptions. Three studies investigate how mental imagery can be used to reduce the effects of negative country of origin stereotypes. Study 1 reveals that participants exposed to country of origin information exhibit automatic stereotype activation. Study 2 shows that self‐focused counterstereotypical mental imagery (relative to other‐focused mental imagery) significantly inhibits the automatic activation of negative country of origin stereotypes. Study 3 shows that this lessening of automatic negative associations persists when measured one day later. The results offer important implications for marketing theory and practice.

Male-male competition can shape some behavioral or morphological traits of males. Here we investigate if this competition could play a role in the persistence of the polymorphism of handedness in human populations. A negative frequency-dependent selection mechanism has been hypothesized, based on the fact that left-handed men may benefit from a "surprise" advantage during fighting interactions because they are rare in human populations. This advantage may thereby enhance the probability of survival of left- handed men and/or their reproductive success through an increase in social status. In this study, we first explored the association between hand preference and lifetime fighting behavior in a population of 1,161 French men. No effect of hand preference on the probability of fighting was detected, suggesting that the innate propensity to fight does not differ between left- and right-handers. However, among men who had been involved in at least one fight during their lifetime, left-handers reported significantly more fights than right-handers. To explore the biological basis of this behavior, we also investigated the testosterone concentration in saliva samples from 64 French university students. Consistent with frequencies of fights, we found a significantly higher average testosterone concentration in left-handers than in right-handers. We suggest that these behavioral and hormonal differences may be acquired throughout life due to previous experiences in a social context and may favor the persistence of left-handers in humans. 相似文献

This study examined the direct and indirect effects of cognitions and anxiety associated with aftershocks on psychological symptoms (anxiety, depression, acute stress) and daily functioning (general and relationship). Participants were 600 adults from Christchurch, New Zealand. Data collection was approximately four months after the fatal 2011 earthquake. Path analysis was used for modelling. Socioeconomic status was directly associated with appraisals of uncontrollability of response to aftershocks. These cognitions were directly related to aftershock anxiety, which heightened general anxiety, depression, and acute stress symptoms. These symptoms were directly associated with relationship and general life dysfunction. Aftershock anxiety plays a significant role in ongoing psychological distress associated with earthquakes. 相似文献

Facilitation of attitude formation through communication: how perceived source expertise enhances the ability to achieve cognitive closure about complex environmental topics 下载免费PDF全文

Attitudes on which people have achieved cognitive closure are better predictors of future attitudes and behavior than open attitudes. In two experiments, we found that factors in communication (source identity, source consensus) can enhance people's ability to achieve cognitive closure on complex environmental topics through an increase in perceived source expertise. Results showed that participants perceived higher levels of source expertise and felt better able to achieve cognitive closure on the environmental technology of carbon dioxide capture and storage (CCS) when the information source had an expert identity compared to a non‐expert identity. The communication of consensus by the information source increased the level of expertise ascribed to the non‐expert source, resulting in an enhanced ability to achieve closure. 相似文献

A Patchwork Text is a creative approach to learning and assessment based on short pieces of reflective writing to promote deep, meaningful reflection. A five-year study was undertaken to explore whether this approach supports postgraduate students’ personal and academic development and the factors that influenced student experience, within one UK university. Our adapted approach encompasses patches of reflection, a structured Reflective Journal, formative feedback, and action learning within a constructively aligned curriculum. Between 2010 and 2015, 100 students attended the MSc Leadership Development programme and 71% (n=71) completed a questionnaire at the end of the first module. The questionnaire contained mainly open questions. The overwhelming majority of responses (89%, n=63) reported their experience of action learning was extremely positive. Eighty-five percent (n=58) reported that the Patchwork Text approach supported their academic development. Seventy-five percent (n=52) agreed the approach was helpful in relation to their summative assessment which comprised a reflective integrated portfolio. Thematic framework analysis of the qualitative data suggests the Patchwork Text approach increased self-awareness and insight; deepened and promoted on-going reflection; and facilitated critical thinking, analysis, and synthesis thereby enabling completion of the summative assignment. Findings suggest the adapted Patchwork Text approach increased students’ self-awareness as well as supporting them with both their summative assignment and the development of academic writing skills. 相似文献
