This exploratory study extended past studies of children's ability to reference the mirror as a tool in locating the source of reflected images to preschoolers' ability to use the affordances of a transparency. Thirty-six children (3.5 to 5 years old) were shown nonreflected lights and lights reflected on a partially transparent, glassy surface. Children did not spontaneously locate the source of the reflected image. However, they were able to verbally discriminate reflected from nonreflected images following training. These findings indicate that, although preschoolers may not spontaneously use transparencies as a perceptual tool, the ability to distinguish visual differences of reflected from nonreflected images on transparencies is likely within preschool children's developmental capacity. 相似文献

ObjectiveTo compare a mindfulness-based intervention with cognitive behavioral therapy (CBT) for the group treatment of anxiety disorders.MethodOne hundred five veterans (83% male, mean age = 46 years, 30% minority) with one or more DSM-IV anxiety disorders began group treatment following randomization to adapted mindfulness-based stress reduction (MBSR) or CBT.ResultsBoth groups showed large and equivalent improvements on principal disorder severity thru 3-month follow up (ps < .001, d = ?4.08 for adapted MBSR; d = ?3.52 for CBT). CBT outperformed adapted MBSR on anxious arousal outcomes at follow up (p < .01, d = .49) whereas adapted MBSR reduced worry at a greater rate than CBT (p < .05, d = .64) and resulted in greater reduction of comorbid emotional disorders (p < .05, d = .49). The adapted MBSR group evidenced greater mood disorders and worry at Pre, however. Groups showed equivalent treatment credibility, therapist adherence and competency, and reliable improvement.ConclusionsCBT and adapted MBSR were both effective at reducing principal diagnosis severity and somewhat effective at reducing self-reported anxiety symptoms within a complex sample. CBT was more effective at reducing anxious arousal, whereas adapted MBSR may be more effective at reducing worry and comorbid disorders. 相似文献

Two studies investigated differences in the comprehension and production of words in 2-year-old children and adults. Study 1 compared children’s speaking and understanding of the names of 12 novel objects presented over three weekly sessions. Study 2 tested adults’ performance under similar training and testing conditions over two sessions. The findings indicated a comprehension advantage for both age groups. A fine-grained temporal analysis of individual words revealed that acquisition does not resemble a linear stage-wise progression from comprehension to production. Rather, dimensions of lexical knowledge develop at different rates, with words acquired, lost, and maintained over the course of learning. The findings support a dynamic and graded view of lexical processing and have implications for understanding what it means to know a word. 相似文献

Two experiments were conducted to examine whether recognition memory for information and/or its source are influenced by confirmation bias. During Phase 1, subjects were shown a summary about the issue of gun control and asked to indicate a position on the issue. During Phase 2, 12 abstracts (Experiment 1) or social media posts (Experiment 2) were shown, one at a time. Posts in Experiment 2 were associated with either friends or strangers. Participants indicated whether they wanted to read a more extensive version of each abstract (Experiment 1) or post (Experiment 2). Phase 3 was the memory phase. Thirty-two abstract titles (Experiment 1) or posts (Experiment 2) were shown one at a time. Participants indicated yes or no, and whether they recognized the titles/posts from the last phase. Recognition memory for information that supported the participants' viewpoint was higher than that for opposing information. 相似文献

The health benefits of regular moderate–vigorous intensity physical activity (MVPA) are well established, yet young adults, particularly parents, often show declines in MVPA and may represent a critical population for intervention. Theory-based correlates used to guide future interventions are scant in this population. The purpose of this study was to examine theory of planned behaviour (TPB) belief-level constructs as correlates of directly assessed MVPA across cohorts of couples without children and with their first child over the initial 12?months. Participants were 238 adults (102 not expecting a child, 136 expecting first child) who completed baseline demographics, belief measures of the TPB and seven-day accelerometry, followed by assessments at 6 and 12 months. Results showed select medium-sized belief-PA correlations with sex and cohort interactions. Overall, women had larger affect-based behavioural belief associations with MVPA than men (e.g. PA relieves stress), and among new parents, mothers showed larger associations with control over MVPA than fathers. Mothers also had larger associations between control beliefs and MVPA compared to women without children (e.g. domestic duties, bad weather). Extremely high means and low variability on the behavioural beliefs show limited room for possible changes in intervention while control beliefs had low means suggesting room for change. Interventions targeting control among new mothers may be paramount for increasing MVPA, yet the TPB yielded less insight into the targets for promoting MVPA among young men. 相似文献

The present study manipulated self-efficacy in an exercise context and examined its effect on the state anxiety of low active women. Participants ( N = 59) were randomly assigned to a low or high efficacy condition, and self-efficacy was manipulated by presentation of computer-generated false feedback after a graded exercise test. Participants returned for a second exercise bout several days later. Efficacy was successfully manipulated and participants in the high efficacy condition reported significantly less anxiety than those in the low efficacy condition both after the graded exercise test and before and after an acute bout of exercise. Results are discussed in terms of the effect of exercise intensity and manipulation condition on anxiety. 相似文献

Self‐discrepancy theory posits that people experience emotional consequences when they perceive discrepancies between their actual and possible selves. However, the extent to which people react emotionally to these self‐discrepancies (i.e. ideal, ought and undesired) may be a function of individual differences in neuroticism. Across both experimental (Study 1; N = 155) and correlational designs (Study 2; N = 139) involving college students, the authors demonstrated that neuroticism moderated the discrepancy–emotion associations such that high‐neuroticism individuals showed elevated depression and anxiety symptoms when their self‐discrepancies were activated. The heightened symptoms were maintained over time. Negative repetitive thoughts (i.e. rumination and worry) were examined as potential mediating mechanisms between the discrepancy × neuroticism interaction and symptoms. Partial support was obtained in that rumination mediated between undesired discrepancy × neuroticism interaction and anxious/depressive symptoms. Implications and possible theoretical extensions for self‐discrepancy theory are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The purpose of this study was to assess the predictive validity of observer ratings of personality and job-related competencies in a selection setting. Based on ratings from multiple raters of both the predictors and the criteria in a sample of MBA students, results indicated that observer ratings of Conscientiousness, Emotional Stability, leadership, and interpersonal skills predicted work performance, team performance, and academic performance. For work performance and team performance, a composite of the four predictors had incremental predictive validity over general mental ability, even after controlling for how well the rater knew the ratee. 相似文献

Previous studies indicate that smokers attrite from military service at significantly higher rates than nonsmokers. The purpose of the current effort is twofold: (a) to examine the implications of treating smoking status as a third military accession quality indicator along with educational credential and mental ability, and (b) to explore preservice psychosocial and health differences between smokers and nonsmokers in support of hypothesis development about reasons for elevated attrition rates in smokers. The results indicate that individuals who smoke tobacco prior to entering military service are almost twice as likely to attrite as nonsmokers, even after statistically controlling for education and mental ability. Moreover, smokers report higher rates of psychosocial and health problems prior to military service. These results support using smoking status as a personnel quality indicator for recruiting and assignment purposes and indicate that smokers, as a group, enter the military with identifiable psychosocial and physical vulnerabilities. 相似文献
