3.5～5.5岁儿童时序认知能力的发展研究

采用被试内设计,研究了90名3.5～5.5岁儿童时序认知能力。结果发现:(1)3.5岁儿童基本上不具备时序认知的能力,儿童的时序认知能力在4.5岁到5.5岁间出现快速发展。到5.5岁左右,大部分儿童已具备时序认知能力。(2)不同年龄的儿童都表现出对现在的认知最好、对过去的认知次之、对将来的认知最差的特点。(3)3.5岁和4.5岁儿童还不具备判断时序先后的能力,到了5.5岁以后,儿童知道了什么是先发生的,什么是后发生的,具备了判断时序的能力。     

从儿童赌博任务看热执行功能的发展

为考察热执行功能的发展,本研究通过儿童赌博任务检测了60名3～4岁儿童(男女各半)的情感决策。实验结果表明,3岁和4岁儿童在此任务上存在显著的年龄差异,4岁组在各试验组的分数呈上升趋势,他们在试验组2、尤其在试验组4和5中选择有利纸牌的次数显著多于3岁儿童,这反映出情感决策在3～4岁期间发展迅速。此外,儿童在此任务上的成绩存在很多可变性,可能掩盖了性别差异,因而,尽管男孩在最后两个试验组的成绩优于女孩,但性别差异在统计上并不显著。     

Face recognition is robust with incongruent image resolution: relationship to security video images

Identifying a criminal captured on conventional security video typically requires matching poor-quality video footage against a high-quality photograph. The authors examined the consequence of such a large discrepancy in image quality. Recognition and matching performance of this incongruent-quality condition was compared with that of a congruent one, in which a high-quality photograph was reduced to a low-quality video. Recognition memory was little affected by this manipulation, whereas matching performance of the incongruent condition enjoyed occasional advantage. The results show that person identification can tolerate a large discrepancy between image qualities of matching stimuli when one of the images is of poor quality.     

Trust me if you can: The effect of driver username on passengers' intention to use ride-sharing service

Building trust and enhancing consumers' participation are critical for the growth of peer-to-peer sharing economy. This research explores the effect of driver username on passengers' intention to use ride-sharing service and its underlying psychological mechanisms. The results indicate that driver username has a significant impact on passengers' intention to use ride-sharing service, as a driver with a real name elicits greater intention to use ride-sharing service than a driver with a screen name (studies 1, 2, 3a, 3b, and 3c). In addition, the effect of driver username on passengers' intention to use ride-sharing service is serially mediated by social presence and trust (study 2). Importantly, the effect of driver username on passengers' intention to use ride-sharing service is moderated by driver reputation (studies 3a, 3b, and 3c). A high (vs. low) reputation facilitates the impact of driver username on passengers' usage intention. Based upon these findings, theoretical and practical implications are discussed.     

Testing the bidirectional relationship between belief in COVID-19 conspiracy theories and psychological distress: A five-wave longitudinal study

Previous studies have primarily focused on understanding why people believe conspiracy theories, especially during societal crises (e.g., the COVID-19 pandemic). The investigation of how such conspiracy beliefs would influence people's mental well-being has just begun recently. The present research aims to address this crucial question by testing the relationships between psychological distress and COVID-19 conspiracy beliefs with a five-wave longitudinal study. On the one hand, COVID-19 conspiracy beliefs could be more appealing to people with heightened distress, as these theories apparently help people to make sense of the uncertainty and life-threatening disease outbreak. On the other hand, conspiracy theories could be a source of existential threat and thus, would induce rather than reduce psychological distress. We tested these possibilities empirically by a series of cross-lagged model analyses. Using the random intercept cross-lagged panel model analysis, we only found a between-person association but not a cross-lagged within-person relationship between the two. COVID-19 conspiracy beliefs was predicted by being more politically conservative. These findings were further corroborated by the supplementary latent growth curve analyses. Overall, our findings suggest that conspiracy beliefs may not induce or reduce psychological distress in the context of COVID-19.     

Sex differences in drinking patterns and behaviours among college students in Singapore

The drinking patterns and behaviours of 1,160 students at the National University of Singapore were studied to assess differences among men and women. Analysis suggests men more than women use alcohol and exhibit more problem behaviour resulting from its use.     

心理长度对二年级儿童数字线估计表征的影响

从心理长度的角度探讨二年级儿童在0~100和0~1000数字范围存在不同表征方式的原因。实验一要求二年级儿童完成长度均为10cm,范围分别为0~100和0~1000的数字线估计任务。实验二要求儿童对长度分别为10cm和18cm,范围均为0~1000的数字线进行估计。结果发现在两个实验中二年级儿童的估计均存在心理长度,但与以往研究的一年级儿童相比,心理长度的范围有所缩小。随着数字范围的增大或长度的减小,儿童的表征方式出现了从线性表征向对数表征的转变趋势。这些结果表明不精确的表征方式可能与心理长度策略的使用有关,心理长度在一定程度上影响了二年级儿童的估计表征方式。     

幼儿外倾性与攻击行为的关系:自我控制和母亲温暖教养的调节作用

本研究以上海市某幼儿园的237名3~6岁幼儿为被试,请母亲填写幼儿气质及教养方式问卷,幼儿园教师评定幼儿的攻击行为,探讨幼儿外倾性与攻击行为的关系,以及自我控制和母亲温暖教养方式在其中的保护作用。结果表明,自我控制和母亲温暖可以调节幼儿外倾性与攻击行为的关系。与较低的自我控制和母亲温暖的幼儿相比,幼儿较高的自我控制和母亲温暖,可以弱化外倾性与攻击行为的正向关联。结果揭示了自我控制和母亲温暖对幼儿外倾性具有保护作用,有助于减弱这些个体的攻击行为。
