Longitudinal examination of the role of goal orientation in cross-cultural adjustment

In this longitudinal study, the authors introduced goal orientation theory to the study of cross-cultural adjustment. The authors examined relationships among dispositional goal orientation, domain-specific self-efficacy, and cross-cultural adjustment. Results indicated that a learning orientation was positively related to sojourners' academic and social self-efficacy, whereas a performance orientation was negatively related to sojourners' social self-efficacy. Sojourners' academic and social self-efficacy were positively related to academic and social adjustment, respectively. A learning orientation was positively related to academic and social adjustment, and the relationship was mediated by self-efficacy. A performance orientation was not related to adjustment. Finally, academic adjustment was positively related to grade point average. The authors discussed implications for research and practices.     

Behavioral expression of learned fear in rats is appropriate to their age at training,not their age at testing

Recent research has shown that learned fear emerges in a response-specific sequence. For example, an odor conditioned stimulus (CS) previously paired with shock elicits behavioral expressions of fear like avoidance at a younger age than it elicits other behavioral expressions of fear like potentiation of the startle response (Richardson, Paxinos, & Lee, 2000). In the present study, the question of whether learned fear is expressed in a manner appropriate to the animal's age at training or its age at testing was explored in three experiments, all using a within-subjects design. The results suggest that learned fear is expressed in a manner appropriate to the rat's age at training, not its age at testing. The Discussion section focuses on the implications of these findings for (1) the developmental analysis of memory and (2) the idea that an aversive CS elicits a central state of fear.     

Testing indirect effect with a complete or incomplete dichotomous mediator

Past methodological research on mediation analysis mainly focused on situations where all variables were complete and continuous. When issues of categorical data occur combined with missing data, more methodological considerations are involved. Specifically, appropriate decisions need to be made on estimation methods of the indirect effects and on confidence intervals for testing the indirect effects with accommodations of missing data. We compare strategies that address these issues based on a model with a dichotomous mediator, aiming to provide guidelines for researchers facing such challenges in practice.     

Defensive pessimism and precautionary action during the COVID pandemic

The purpose of this research was to test, in the context of the COVID-19 pandemic, the hypothesis that individuals who use defensive pessimism as a strategy to manage anxiety are likely to act to prevent or mitigate negative outcomes. Across three crowd-sourced samples (Total N = 1416), defensive pessimism was correlated with self-reports of more precautionary behavior (Studies 1, 2, & 3) and fewer COVID-positive results (Study 3).     

幼儿空间表征的初步实验研究

本实验分别从运动、照片和“地图”方面对4岁、5岁和6岁儿童在真实空间中的心理旋转及对参照信息的使用等空间表征的发展作了初步考察,结果发现,(1)运动部分客体定位最容易,“地图”部分其次,照片部分最难,(2)心理旋转能力在不同的实验方式下有不同的表现;(3)儿童的自我中心性反应也是相对的,并不一律依存于儿童的年龄,还与客观标记的作用有关。     

The sensory match effect in recognition memory: Perceptual fluency or episodic trace?

The sensory match effect in recognition memory refers to the finding that recognition is better when the sensory form in which an item is tested is the same as that in which it was studied. This paper examines the basis for the sensory match effect by manipulating whether a studied fragmented picture is tested with the same or a complementary set of fragments in a recognition memory test (Experiment 1) and in a fragment-identification test (Experiment 2). Assuming that fragment identification is a direct measure of perceptual fluency, we expected identical patterns of results across the two tests if perceptual fluency accounted for the sensory match effect in recognition memory. Instead, recognition memory showed a robust overall sensory match effect (the same fragmented image was recognized better than the complementary image), whereas fragment identification showed no overall sensory match effect (the same fragmented image was identified no better than the complementary fragmented image). Experiments 3 and 4 combined the two responses and showed that the basis for the sensory match effect in recognition memory was a subject’s ability to recognize the matching fragments in the absence of conceptual information (when the test stimulus could not be identified), supporting the idea that the episodic trace of the sensory code is responsible for the sensory match effect in recognition memory. Experiment 5 demonstrated that subjects are able to use this sensory code as the sole basis for recognition memory.     

Ⅱ型糖尿病患者的行为特征研究

使用修订行为特征问卷调查了１１２名Ⅱ型糖尿病患者和１４７名健康对照组。结果表明： １．男性患者比健康人更加抑郁;２．女性患者比健康人更加焦虑、抑郁和愤怒;３．不论是男性 还是女性,此问卷可显著地区分这两组,越抑郁的人,越不焦虑的人,越缺少合理化这种心理 防御机制的人,越可能是糖尿病患者。结合其它的研究结果,认为存在着Ⅱ型糖尿病易感性 行为特征,主要表现为：高抑郁;低焦虑;对应激的唤醒水平低;不善于使用心理防御机制来 保护和伪装自己;寻找一些有趣的事情：回避痛苦事件;不善于延迟的满足,要求马上得到满 足;注意易分散等。     

5—11岁儿童两种空间关系认知发展的实验研究

本实验是研究5—11岁儿童对面积和垂直这两种空间关系认知的发展。判断相等面积是探讨儿童掌握“等量减等量所余相等”原理的发展过程。结果表明:课题中不同变化因素对儿童认知的影响是不一样的;儿童判断相等面积的认知过程主要可分为直觉判断和推理判断,似乎存在一种由前者发展到后者的过渡形态。儿童处理垂直关系时,除了垂直于斜面和垂直于水平面的形式之外,还有处于这两者之间的一种中间形式存在,这是从垂直于斜面向垂直于水平面逐渐变化的发展过程。两个实验结果都表现随年龄而发展的趋势,其中有两个突出的阶段性特点,即六至七岁发展最快,各项指标差别显著,七至九岁组成绩上未显露增长,在这一阶段中儿童认知易受课题条件变化的影响,各个指标较其它年龄组变化大,这可能是发展中的过渡阶段的特点。     

儿童对物体运动速度的认知发展——4—10岁儿童比较匀速直线运动物体速度的实验(下)

本文是前一同名报告的继续,补充介绍本研究的结果。 本研究的全部实验结果表明:1)儿童对速度的认知是从局部到整体的发展。2)物体运动相对位置对速度认知的影响早于并大于物体运动距离的影响。3)物体运动时间的先后(开始或停止)对速度认知的影响大于物体运动时间长短的影响。4)在儿童速度认知发展中,7、8岁是一个快速发展阶段。5)速度观念的发展是在直观与概念的矛盾运动中进行的。6)10岁左右,儿童形成速度概念的内部条件似已基本具备。
