Onset of psychosis typically occurs in young adulthood, and is likely to be preceded by anxiety, low mood, suspiciousness and perceptual anomalies. Where these develop into mild or brief psychotic experience, and impact on functioning, young people are identified as being at risk of psychosis. Early intervention may reduce severity or delay transition to psychosis, and yield significant healthcare cost savings. This study examined the impact of an online attachment-based imagery task on paranoia, anxiety, mood and self-esteem, in college students. An experimental design was used to compare the effects of secure and anxious-ambivalent attachment imagery. A total of 301 college students, aged 18–48 years (M?=?20.1, SD?=?2.976), were randomly assigned to one of the two imagery conditions, and assessed pre and post imagery task on standardised measures of paranoia, anxiety, mood and self-esteem. A series of mixed model analyses of variance showed that participants in the secure attachment imagery condition reported lower levels of paranoia, anxiety and negative mood, and higher levels of positive mood and self-esteem, compared with those in the anxious-ambivalent attachment imagery condition. The study is limited by the lack of a neutral control condition and follow-up measures. Nevertheless, study demonstrated the impact of attachment-based imagery on paranoia. If these effects are replicated with ‘at risk mental state’ groups, and maintained at follow-up, online imagery may provide a safe and highly accessible means of attenuating paranoia in young people at risk of developing psychosis. 相似文献

In experimental contexts, affect-related word lists have been widely applied when examining how cognitive processes interact with emotional processes. These lists, however, present limitations when studying the relation between emotion and cognitive processes such as time and number processing because affective words do not inherently contain time or quantity information. Live events, in contrast, are experienced by an observer and therefore inherently carry affect information. Unfortunately, existing life-event lists and inventories have been largely applied within clinical contexts as diagnostic tools, and therefore are not suitable for many experimental contexts because they do not contain a balanced number of reliably positive, negative, and neutral life events. In Experiment 1, we create a standardized affect-related life-events list with 171 positive, negative, and neutral affect-related life events. In Experiment 2, we show that strength of affect and significance of the event are integral dimensions, suggesting that these two features are difficult to separate perceptually. The implications of these findings and some potential future applications of the created life-events list are discussed. 相似文献

Recent interest has emerged in understanding the neural mechanisms by which deficits in emotion regulation (ER) early in development may relate to later depression. Corticolimbic alterations reported in emotion dysregulation and depression may be one possible link. We examined the relationships between emotion dysregulation in school age, corticolimbic resting-state functional connectivity (rs-FC) in preadolescence, and depressive symptoms in adolescence. Participants were 143 children from a longitudinal preschool onset depression study who completed the Children Sadness Management Scale (CSMS; measuring ER), Child Depression Inventory (CDI-C; measuring depressive symptoms), and two resting-state MRI scans. Rs-FC between four primary regions of interest (ROIs; bilateral dorsolateral prefrontal cortex [dlPFC] and amygdala) and six target ROIs thought to contribute to ER were examined. Findings showed that ER in school age did not predict depressive symptoms in adolescence, but did predict preadolescent increases in dlPFC-insula and dlPFC-ventromedial PFC rs-FC across diagnosis, as well as increased dlPFC-dorsal anterior cingulate cortex (dACC) rs-FC in children with a history of depression. Of these profiles, only dlPFC-dACC rs-FC in preadolescence predicted depressive symptoms in adolescence. However, dlPFC-dACC connectivity did not mediate the relationship between ER in school age and depressive symptoms in adolescence. Despite the absence of a direct relationship between ER and depressive symptoms and no significant rs-FC mediation, the rs-FC profiles predicted by ER are consistent with the hypothesis that emotion dysregulation is associated with abnormalities in top-down control functions. The extent to which these relationships might confer greater risk for later depression, however, remains unclear. 相似文献

The present study examined the effect of gender-based stereotype threat (ST) on the mathematics performance of high school students in Uganda, East Africa, as moderated by students’ stereotype endorsement and/or their perceptions of stereotypic expectancies by others. Participants were 190 ninth grade students (age 14–15, senior 2, in Uganda) from all-female and coed boarding schools. Only perceived stereotypic expectancies by others significantly moderated ST effects on performance. A reminder of cross-gender comparisons led both young women and young men to underperform if they assumed that the researchers expected their own gender to do worse than the other gender. Importantly, students’ perceptions of the stereotypic expectancies of authority figures (i.e. researchers) mattered more for predicting their math performance than did students’ own endorsement of stereotypes. Collectively, these findings support a basic assumption of ST theory– that knowledge of a cultural stereotype is a prerequisite to the ST experience. Therefore, studies conducted with younger samples and in diverse cultural contexts should establish participants’ awareness of the stereotype in question. Also, regarding gender and math stereotypes, it should not be assumed that males will always be immune from stereotype-based performance deficits on quantitative tasks when tested in different cultures. Finally, results suggest that conveying an expectation that young men and young women have equal ability and potential might be important to preventing ST among younger age groups. 相似文献

Attention is critical for everyday functioning. Posner and Petersen’s model of attention describes three neural networks involved in attention control—the alerting network for arousal, the orienting network for selecting sensory input and reorienting attention, and the executive network for the regulatory control of attention. No longitudinal research has examined relative change in these networks in children. A modified version of the attention network task (ANT) was used to examine changes in the three attention networks, three times over 12 months, in 114 6-, 8- and 10-year-olds. Findings showed that the alerting network continued to develop over this period, the orienting network had stabilized by 6 years, and the conflict network had largely stabilized by 7 years. The reorienting of attention was also assessed using invalid cues, which showed a similar developmental trajectory to the orienting attention network and had stabilized by 6 years. The results confirm that age 6 to 7 years is a critical period in the development of attention, in particular executive attention. The largest improvement over the evaluation period was between 6 and 7 years; however, subtle changes were found in attention beyond 8 years of age. 相似文献

Theoretical models and empirical evidence suggest that brooding, the maladaptive sub-component of depressive rumination, is associated with a sub-set of depressogenic interpersonal difficulties characterised by submissive interpersonal behaviours and rejection sensitivity. This study tested whether these cognitive and interpersonal vulnerability factors independently predicted future depression and investigated their interdependence in predicting depression. A heterogeneous adult sample completed self-report measures assessing depressive symptoms, brooding, reflection, rejection sensitivity and maladaptive interpersonal behaviours, at baseline and six months later. When examined separately, brooding and an interpersonal component reflecting submissive, (overly-accommodating, non-assertive, and self-sacrificing) interpersonal behaviours each prospectively predicted increased depressive symptoms six months later, after controlling for baseline depressive symptoms and gender. When examined together, the submissive interpersonal style but not brooding predicted depression, indicating that this maladaptive interpersonal style may mediate the effect of brooding on future depression. Thus, the effects of brooding on depression may in part depend on its association with an interpersonal style characterised by submissiveness. 相似文献

Successive relearning improves performance on a high-stakes exam in a difficult biopsychology course
Jessica L. Janes John Dunlosky Katherine A. Rawson Aaron Jasnow 《Applied cognitive psychology》2020,34(5):1118-1132
Successive relearning combines two effective learning techniques (retrieval practice and spaced practice) and involves practicing retrieval until some level of mastery has been reached (i.e., at least one correct retrieval attempt) in each of multiple sessions. Several laboratory studies have demonstrated the promise of successive relearning for enhancing student learning, but attempts to evaluate its effectiveness in authentic educational contexts are limited. In the current research, we implemented successive relearning in a difficult biopsychology course to examine its effectiveness at enhancing student learning on a high-stakes exam. Students successively relearned some course content via a virtual flashcard program, whereas other course content was learned with business-as-usual activities. In two experiments, successive relearning boosted students' learning of course content by at least 10% (with ds ranging from 0.54 to 1.10). These findings suggest that implementing successive relearning in courses can be an effective method of promoting student achievement. 相似文献
