Recent research suggests that one can have the feeling of being the cause of an action’s outcome, even in the absence of a prior intention to act. That is, experienced self-agency over behavior increases when outcome representations are primed outside of awareness, prior to executing the action and observing the resulting outcome. Based on the notion that behavior can be represented at different levels, we propose that priming outcome representations is more likely to augment self-agency experiences when the primed representation corresponds with a person’s behavior representation level. Three experiments, using different priming and self-agency tasks, both measuring and manipulating the level of behavior representation, confirmed this idea. Priming high level outcome representations enhanced experienced self-agency over behavior more strongly when behavior was represented at a higher level, rather than a lower level. Thus, priming effects on self-agency experiences critically depend on behavior representation level.  相似文献

The dorsolateral prefrontal cortex (DLPFC) plays a crucial role in working memory. Notably, persistent activity in the DLPFC is often observed during the retention interval of delayed response tasks. The code carried by the persistent activity remains unclear, however. We critically evaluate how well recent findings from functional magnetic resonance imaging studies are compatible with current models of the role of the DLFPC in working memory. These new findings suggest that the DLPFC aids in the maintenance of information by directing attention to internal representations of sensory stimuli and motor plans that are stored in more posterior regions.  相似文献

Background and Objectives: Previous research indicates that early life adversity may heighten stress reactivity and impair mechanisms for adaptive coping, suggesting that experience of stress in early life may also potentiate adults' physiological vulnerability to stress in later life. The study tested this hypothesis by investigating whether the experience of stressful events and circumstances (SEC) in childhood or adolescence amplified the effect of adulthood SEC on physiological dysregulation (allostatic load, AL) in later midlife. Design: Observational data were used in the present study. Physiological functioning was measured in later midlife (participants' age ranged from 49 to 63 years). Both childhood/adolescence and adulthood SEC were reported retrospectively on the same occasion. Methods: Participants were 5309 Danish men and women from Copenhagen Aging and Midlife Biobank (CAMB). SEC included socioeconomic and family factors. The AL index was based on nine cardiovascular, metabolic, and immune biomarkers. Results: Experience of SEC in both early life and adulthood independently predicted higher AL. In men, experience of SEC in early life also potentiated the effect of SEC in adulthood on AL. Conclusions: The results provide further insight into the mechanisms behind the “biological embedding” of childhood stress.  相似文献

Drawing on the relational turbulence model, this study queries whether it is the amount of relational uncertainty and partner interference in a relationship, or the magnitude of an increase in these mechanisms over time, that accounts for decreased relationship satisfaction for new parents. To test these competing hypotheses, a longitudinal study of 78 couples was conducted in which both partners completed surveys about their relationship at 4 time points during the transition to parenthood. Multilevel modeling revealed that the amount and the increase of relational uncertainty and partner interference were negatively associated with relationship satisfaction when considered separately, but when evaluated in combination, the magnitude of an increase in these variables was the stronger predictor of relationship satisfaction.  相似文献

The present study examined racial, ethnic, and gender differences in family composition substance abuse, and mental health issues, such as depression and self-esteem among adjudicated juvenile offenders. Results revealed a negative relationship between depression and self-esteem among all ethnicities and family compositions. Caucasians reported greater incidence of substance abuse than did African American and Hispanic youth. Moreover, in reconstituted families, Caucasians had lower self-esteem scores than did other ethnicities. The findings illustrate the complexities of risk to substance use among high-risk populations, particularly as they relate to familial factors and the importance of intensive family therapy among this population.  相似文献

The objectives of this research were to evaluate the efficacy of computer-delivered personalized normative feedback among heavy drinking college students and to evaluate controlled orientation as a moderator of intervention efficacy. Participants (N = 217) included primarily freshman and sophomore, heavy drinking students who were randomly assigned to receive or not to receive personalized normative feedback immediately following baseline assessment. Perceived norms, number of drinks per week, and alcohol-related problems were the main outcome measures. Controlled orientation was specified as a moderator. At 2-month follow-up, students who received normative feedback reported drinking fewer drinks per week than did students who did not receive feedback, and this reduction was mediated by changes in perceived norms. The intervention also reduced alcohol-related negative consequences among students who were higher in controlled orientation. These results provide further support for computer-delivered personalized normative feedback as an empirically supported brief intervention for heavy drinking college students, and they enhance the understanding of why and for whom normative feedback is effective.  相似文献

An important part of our Theory of Mind—the ability to reason about other people's unobservable mental states—is the ability to attribute false beliefs to others. We investigated whether processing these false beliefs, as well as similar but nonmental representations, is reliant on language. Participants watched videos in which a protagonist hides a gift and either takes a photo of it or writes a text about its location before a second person inadvertently moves the present to a different location, thereby rendering the belief and either the photo or text false. At the same time, participants performed either a concurrent verbal interference task (rehearsing strings of digits) or a visual interference task (remembering a visual pattern). Results showed that performance on false belief trials did not decline under verbal interference relative to visual interference. We interpret these findings as further support for the view that language does not form an essential part of the process of reasoning online (“in the moment”) about false beliefs.  相似文献

In this research, hierarchical linear modeling (HLM) was used to address how school context influences the likelihood of transitioning between stages of cigarette smoking as well as modifies the individual-level risk factor of self-regulation. Survey data were collected from 25,186 middle and high school students attending 38 public schools in Kentucky. Results show that students are less likely to increase use in schools with higher levels of teacher discipline and faculty involvement. The analyses of the multi-level interactions between self-regulation and school context reveal that students possessing low emotional regulation are more likely to initiate experimental smoking in schools with poor levels of discipline and involvement than similar types of students in schools with higher levels of these characteristics. This study illustrates how psychological risk factors for substance use may vary across social environments.  相似文献

The possibility of unconsciously evoked emotions is often denied because awareness of an emotion's cause is considered to be precisely what produces the emotion. However, we argue that because emotional responding is important for successful living, both global and specific emotional responses can be induced without awareness. The present research used quick and super-quick subliminal priming techniques, and cognitive, feelings, and behavioral measures, to test this hypothesis. Our results show that both global moods and specific emotions can be evoked without conscious awareness of their cause.  相似文献
