中央执行注意资源在消极和积极特征捆绑中的作用

鉴于以往研究未明确视觉工作记忆中特征捆绑是否需要注意资源,以及未考察积极加工条件下的特征捆绑等问题,本研究运用双任务干扰范式,通过两个实验分别在消极加工和积极加工条件下考察了联结客体的特征加工和特征捆绑,以及中央执行注意资源在特征捆绑中的作用。结果表明：联结客体的特征加工不但存在双重存储机制,还存在双重操作机制,这一结果拓展了Wheeler和Treisman（2002）的特征捆绑理论;联结客体的特征捆绑可分为消极特征捆绑和积极特征捆绑两种类型,消极特征捆绑不需要中央执行注意资源的参与,而积极特征捆绑则需要中央执行注意资源的参与。

Who is more proactive,the optimist or the pessimist? Exploring the role of hope as a moderator

This research tested the existence of a moderation role of hope on the effects of optimism and pessimism over proactive coping in a sample survey of 343 subjects. The results showed that optimism explained proactive coping, independent of hope. However, hope appeared to moderate the relationship between pessimism and passive coping, a criterion variable that emerged from the psychometric analysis of the proactive coping measure. Specifically, for individuals low in pessimism, being high or low in hope did not impact coping, but for individuals high in pessimism, having higher levels of hope reduced passive coping. A deeper analysis also indicated that this was particularly due to the moderating role of the pathways dimension of hope. We discuss these results in light of different adaptive strategies of optimists and pessimists and draw implications for psychological research and practice.     

Active versus passive learning and testing in a complex outside built environment

A review of the evidence on active and passive learning in virtual environments (VEs) suggests that both conditions have shown superiority under some conditions of learning and testing, but there is no consistent outcome pattern. Measures of transfer between virtual and real environments have also revealed a variety of outcomes. Following either active or passive learning in a VE, experiment 1 assessed measures of orientation and distance estimation in that VE and in a real-world equivalent environment. On measures of direct and relative distance, more accurate estimates were found for active than passive VE explorers. A suggestion was also noted for the orientation estimates to benefit from real-world rather than VE testing. With an improvement to the procedure, experiment 2 found similar real versus virtual orientation judgements, suggesting that an opportunity for active learning during the test procedure probably influenced orientation measures in experiment 1. We conclude that the effects of interactivity are unreliable and vary with the measures used, and that testing in virtual and real environments leads to similar outcomes.     

Implicit theories of mental health predict anxiety and depression during the COVID-19 pandemic in China: The mediating effect of coping styles

This research investigated how implicit theories of mental health (ITMH) influence people's experience of anxiety and depression symptoms during the COVID-19 pandemic in China. Two thousand and 44 Chinese completed the study during an emergent outbreak of the COVID-19 pandemic in Shaanxi, China. The results suggested that ITMH significantly influence people's experience of anxiety and depression symptoms. Both active and passive coping styles significantly mediated the relationship between ITMH and anxiety/depression, with active coping style as a stronger mediator than passive coping style. Implications of the current research for improving people's mental health during pandemics of infectious diseases and directions for future research are discussed.     

Students' defending and passive bystanding behaviours when witnessing school bullying in North Western Ethiopia: Roles of personal and situational factors

Guided by Thornberg et al.'s (2012) framework on motivation to intervene, the present study examines whether personal and situational factors are associated with defending and passive bystanding behaviours in school bullying. Self-reported survey data were collected from 612 students (aged 12–16 years) attending grades 7, 8, 9, and 10 in East Gojjam Administrative Zone, North Western Ethiopia. Hierarchical regression analysis revealed that the strongest, significant predictors of defending were self-efficacy for defending (β = .215, p = .000), affective empathy (β = .173, p = .000), students' experience as victim (β = .119, p = .002), personal sense of power (β = .119, p = .006), followed by moral disengagement (β = .118, p = .002), and age level (β = −.082, p = .036). All variables jointly explained 18.6% of the total variance in defending, F (12, 599) = 11.397, p < .00; with medium effect size (f² = 0.23). In contrast, the strongest predictors of passive bystanding were moral disengagement (β = .233, p = .000), perceived costs and benefits of defending (β = −.163, p = .000), self-efficacy (β = −.139, p = .003), students' experience as victim (β = .097, p = .014), followed by gender (β = −.080, p = .042). The model explained 16.7% of the total variance in passive bystanding, F (12, 599) = 10.043, p < .001; with medium effect size (f² = 0.20). The findings enrich our understanding of factors associated with defending and passive bystanding behaviours. The implications for intervention are discussed.

Relations of Age to Cognitive and Motivational Elements of Impulse Control in Boys With and Without Externalizing Behavior Problems

In a cross-sectional study of 83 unmedicated boys, 6 to 16 years of age (M = 10.6, SD = 2.1), attending public (N = 48) and therapeutic schools for behaviorally disturbed children (N = 35), we examined relations of externalizing psychopathology to age-dependent change in performance on cognitive and motivational dimensions of impulse control assessed by laboratory tasks. When we controlled for internalizing symptoms and IQ or school achievement, all children showed improving competence with increasing age on both dimensions over the age range of the sample. Children with externalizing problems performed more poorly on both dimensions at all ages than children without such problems. Comparing age-dependent competence for the two groups, a model of convergent maturation in cognitive aspects of impulse control, and a model depicting a stable deficit in motivational aspects of impulse control in those children with externalizing behavior problems, relative to those without such problems, emerged. Studies of individual growth in impulse control, together with correlates of growth, are needed to validate these observations.Project on Human Development in Chicago Neighborhoods     

Acquisition and maintenance of trusting behavior

This study determined whether a two-person exchange situation contained natural contingencies for trusting behavior or whether external contingencies were necessary. Pairs of college students worked matching-to-sample problems for money. On each trial there was one problem and the subjects determined which of them would solve it. Trusting behavior was defined as an increase in the number of consecutive problems each subject allowed his partner to work during sessions that also ended with an equitable distribution. Simply, trust was a temporary deviation from equity. A subject could give the problem to the other person (cooperate), or not respond and let the other person take the problem (share). Other possibilities were for both subjects to try to take the problem (complete), or for neither subject to respond and thereby let the person who worked the last problem also work the next one (passive trust). When only four lever pulls were required to distribute a problem (no external contingencies to reach either equity or trust) subjects reached equity, but only minimal trust (strict alternation of single problems) developed in 18 sessions. When 30 or 60 lever pulls were required to distribute a problem (smaller response requirement for passive trust and therefore a contingency for trust), trusting behavior developed after a few sessions (fixed ratio 30) or after several trials of the first session (fixed ratio 60) and it ordinarily expanded gradually to 10 to 15 consecutive problems through passive trust. The aversiveness of the inequity involved in trusting appears to necessitate a contingency for acquisition. Once trust develops, however, this aversiveness is reduced as subjects learn the inequity is only temporary (e.g., once trust was acquired at fixed ratio 60 it was maintained at fixed ratio 4, which would not initially produce it), and the direction of the inequity appears to become of questionable importance (e.g., being behind was alternated over rather than within sessions and usually not in a systematic manner).     

视剥夺及视剥夺学习后Jun样蛋白在雏鸡两侧半球中不同表达的研究

该实验利用免疫组化技术,在已有实验的基础上进一步观察比较了左眼视剥夺及单眼学习后,Ｊｕｎ样蛋白在雏鸡两侧半球ＨＶ和ＬＰＯ中表达的差异。实验结果表明：１．视剥夺２、２４、４８、７２小时后观测到Ｊｕｎ样蛋白在左、右半球ＨＶ和ＬＰＯ中的表达逐渐增高,并且于视剥夺４８小时表达到达峰值。同时仅在视剥夺２小时后观测到两半球ＬＰＯ中Ｊｕｎ样蛋白的表达存在差异,在其余各视剥夺时程中两侧半球的ＬＰＯ、ＨＶ中Ｊｕｎ样蛋白的表达均无显著差异。２．视剥夺２小时和２４小时后均在学习后７０分钟组中观测到Ｊｕｎ样蛋白在左、右半球的ＨＶ和ＬＰＯ中表达的显著升高,而在视剥夺２小时学习后１０分钟只观测到左半球ＨＶ和ＬＰＯ中Ｊｕｎ样蛋白表达的显著升高,在视剥夺２４小时学习后１０分钟中仅观测到左半球ＬＰＯ中Ｊｕｎ样蛋白的显著升高。同时也仅在视剥夺２小时学习后１０分钟观测到两侧半球ＨＶ、ＬＰＯ中Ｊｕｎ样蛋白表达的显著性差异。３．无论单纯视剥夺组还是单眼学习组,各组同侧半球中ＬＰＯＪｕｎ样蛋白的表达显著高于ＨＶ的Ｊｕｎ样蛋白的表达现象在视剥夺４８小时后消失。
