Research and theory suggest that deficits in trait positive affectivity (PA) and in capacity for executive control of attention (i.e., attentional control or AC) may each intensify risk for depressive symptoms associated with high trait negative affectivity (NA). In contrast, high levels of PA and AC should protect against that risk. However, prospective tests of such predictions are rare. Furthermore, if PA and AC both modulate NA-related risk, it remains to be seen if those effects are independent and complementary or if they operate in an overlapping manner. This study assessed baseline temperament and change in depressed mood across one month in a sample of 125 adolescents. Results supported both PA and AC as modulators of NA’s association with changes in depressed mood. Furthermore, results suggested that these modulating effects are largely non-overlapping and complementary, such that when both PA and AC are low, high NA predicts increases in depressed mood. In contrast, high NA predicts decreases in depressed mood when both PA and AC are high. Limitations of these findings, directions for future research, and implications for prevention are discussed.  相似文献

The current study examined mechanisms through which trait negative affectivity (NA) and effortful control (EC) prospectively predict increases in depressive symptoms in a community sample of 110 adolescents (mean age=16.40 years) in a 9-week, multi-wave diary study. We hypothesised youth with high NA and low EC would experience greater increases in depressive symptoms because they generate more maladaptive cognitive responses to stress. NA predicted greater event-specific rumination and negative cognitive style across the study period. After controlling for trait cognitive vulnerabilities, only event-specific rumination mediated the effect of NA on subsequent depressive symptoms, suggesting that high-NA youth are more likely to ruminate about stressful events, which then predicts increases in depressive symptoms. EC did not moderate the effects of NA on either depressive symptoms or cognitive responses to stress. Results are discussed in terms of vulnerability-stress models linking temperament and depressive symptoms in adolescence.  相似文献

Several studies have evaluated false positives and false negatives produced with partial interval recording (PIR) and momentary time sampling (MTS) using simulated data. However, no study to date has evaluated false positives and negatives using a large sample of non‐simulated behaviors. In addition, few studies have evaluated whether interval methods of data collection alter trends that are evident in continuous records. We conducted three experiments to evaluate the extent to which various interval sizes of MTS and PIR produced false negatives (Experiment 1), false positives (Experiment 2), and trends that were inconsistent with the continuous records (Experiment 3). Collectively, the results show the following: (i) 10‐s PIR and 10‐s MTS produced few false negatives and few false positives (i.e., both were sensitive) to changes in duration events; (ii) 10‐s PIR produced very few false negatives, but an unexpected high percentage of false positives for frequency events; and (iii) each interval size of PIR and MTS produced a high percentage of changes in trending for duration events and frequency events. We briefly discuss the potential limitations and clinical implications of these findings. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

It has become widely accepted that the direction of another individual's eye gaze induces rapid, automatic, attentional orienting, due to it being such a vital cue as to where in our environment we should attend. This automatic orienting has also been associated with the directional-arrow cues used in studies of spatial attention. Here, we present evidence that the response-time cueing effects reported for spatially nonpredictive gaze and arrow cues are not the result of rapid, automatic shifts of attention. For both cue types, response-time effects were observed only for long-duration cue and target stimuli that overlapped temporally, were largest when the cues were presented simultaneously with the response-relevant target, and were driven by a slowing of responses for invalidly cued targets rather than speeding for validly cued ones. These results argue against automatic attention-orienting accounts and support a novel spatial-incongruency explanation for a whole class of rapid behavioural cueing effects.  相似文献

ABSTRACT

Although preschoolers have strong expectations about the pedagogical nature of pointing gestures (Csibra & Gergely, 2006), more recent work has shown that preschoolers prefer to use informants’ spoken language, not their pointing gestures, to make judgments about their reliability (Palmquist & Jaswal, 2015). Here, we explored children’s inferences about pointers using a standard selective trust paradigm. Specifically, we asked whether 4- and 5-year-olds generalize reliability across communicative domains (from pointing ability to speaking ability). We found that children preferred to make generalizations about pointers’ reliability when they had conveyed semantic, but not episodic, knowledge. Individual differences in theory of mind also predicted children’s willingness to make generalizations about pointers’ reliability. Both sets of results suggest that multiple factors (i.e., the type of knowledge an informant shares and individual differences in children’s cognitive development) affect whether preschoolers generalize others’ reliability across domains.  相似文献

Object use is a ubiquitous characteristic of the human species, and learning how objects function is a fundamental part of development. In this article the authors examine the role that intentionality plays in children's understanding of causal relationships during observational learning of object use. Children observed demonstrations in which causally irrelevant and causally relevant actions were performed to achieve a desired goal. The intentionality of these actions was manipulated using verbal markers. Irrelevant actions were performed either intentionally (“There!”) or accidentally (“Whoops! I didn't mean to do that!”). Three-, 4-, and 5-year-olds, but not 2-year-olds, were less likely to imitate causally irrelevant actions performed accidentally than when they were performed intentionally. This suggests that older children used intentionality to guide causal inference and perceived intentional actions as causally effective and accidental actions as causally ineffective. Findings are discussed from an evolutionary perspective in relation to the cultural transmission of tool-use knowledge.  相似文献

We investigate the possibility of two distinct approaches to autonomy satisfaction—one that is contextually “assisted” and one that is individually “asserted”. Exploratory and confirmatory factor analyses (Pilot Study and Study 1; N = 449) develop and validate the two-factor structure. We then show that asserted and assisted autonomy orientations predict psychological wellbeing through distinct pathways (i.e., highly active/agentic vs. interdependent). In Study 2 (N = 206), we examine the sociodevelopmental antecedents of each type of autonomy satisfaction, revealing that assisted autonomy is associated with having had authoritiative parents, whereas asserted autonomy is associated with having had authoritarian parents. In Study 3 (N = 109) we show that asserted—but not assisted—autonomy predicts the integration of negative life experiences. Finally, in Study 4 (N = 202), we examine the degree to which assisted and asserted autonomy moderate responses to conflict in need-thwarting contexts, showing that assisted autonomy predicts an acquiescent coping style, whereas asserted autonomy predicts an assertive negotiation style.  相似文献

Associations between smoking behavior and polymorphisms in the dopaminergic genes (DAT1 and DRD2) were tested by using within- and between-family measures of allelic transmission in 2,448 young adults from the National Longitudinal Study of Adolescent Health. The 9-repeat allele of the dopamine transporter gene polymorphism (DAT1) was inversely associated with smoking in samples that included all subjects and only those who had initiated smoking, accounting for approximately 1% of the variance. Never smokers and current nonsmokers had an excess transmission of the 9-repeat allele compared with regular smokers, suggesting a protective effect of the 9-repeat allele, which is hypothesized to alter synaptic dopamine levels.  相似文献

Research shows that behavioral skills training (BST) and in situ training (IST) are effective interventions for teaching safety skills to children. In addition, the efficiency of these interventions can be increased when parents, teachers, or peers are taught to implement them. The purpose of this study was to replicate Novotny et al. (2020) and evaluate a web-based program for teaching parents to conduct BST to teach safety skills to prevent gunplay. We randomly assigned 18 children to the parent-conducted BST group or a control group and evaluated the intervention in a posttest only control group design. Children in the control group or treatment group who did not score a three in the in situ assessment (do not touch, get away, and tell an adult) received IST from their parents and were assessed again. Results showed that safety skill scores were statistically significantly higher in the treatment group than in the control group. Furthermore, there was a statistically significant increase in safety skills scores following IST for children who received it.  相似文献
