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。     

基于干扰物特征的统计规则对注意抑制效应的影响

采用经典的额外单例范式的变式, 通过操纵基于干扰物颜色的统计规则, 考察其对注意抑制效应的影响。结果发现：(1)当迫使被试采取特征探测策略时, 与无颜色独子的条件相比, 被试在所有呈现独子的条件中反应都显著较快; (2)与呈现低概率颜色独子条件相比, 呈现高概率颜色独子条件下被试的反应显著较快。研究表明, 统计规则对注意的影响不局限于刺激位置, 基于干扰物特征的统计规则也会影响注意抑制效应的大小。     

Authoritarian–benevolent Leadership and its Effect on Graduate Student Creativity: The Mediating Role of Intrinsic Motivation

Despite numerous studies demonstrating that authoritarian leadership and benevolent leadership exert incompatible influence on an individual’s creativity, the combined effects of authoritarian leadership and benevolent leadership on an individual’s creativity and the related mechanisms have yet to be explained. This study tests a model that considers the combined effects of authoritarian and benevolent leadership on graduate student creativity in the universities in China, while also examining the mediating role of the intrinsic motivation of graduate students. Multisource data were collected from 297 graduate students in 60 university scientific research teams in China. The results show that when authoritarian leadership and benevolent leadership are in congruence, the intrinsic motivation of graduate students and their creativity increase as supervisor authoritarianism and benevolence increases. When authoritarian leadership and benevolent leadership are in discrepancy, the intrinsic motivation of graduate students is higher when low supervisor authoritarianism is combined with high benevolence; however, the findings also show that low authoritarian leadership combined with high benevolent leadership would not increase graduate student creativity. The relationship between authoritarian–benevolent leadership and graduate student creativity is partially mediated by intrinsic motivation. The theoretical and practical implications of the results are discussed.     

内隐社会认知:社会性决策的个人背景效应

通过两个实验研究了个人背景对其社会性决策的影响。实验一采用 2× 2混合设计 ,其中被试性别为组间因素 ,策略类型为组内因素 ;结果发现不同性别的被试在选择决策策略时表现出了差异 ,其中男性更倾向于选择“综合比较”的策略 ,但女性却没有表现出对策略的偏向。实验二则选择 14项个人背景资料作为自变量 ,以“才—情”决策倾向为因变量 ,进行多元逐步回归分析 ,结果发现被试的家庭所在地、性别差异以及对自己容貌的评价等变量显著地影响了决策倾向。

Effects of shape parameters on the attractiveness of a female body

Various researchers have suggested that certain anthropometric ratios can be used to measure female body attractiveness, including the waist to hip ratio, Body Mass Index (BMI), and the body volume divided by the square of the height (Volume-Height Index). Based on a wide range of female subjects and virtual images of bodies with different ratios, Volume-Height Index was found to provide the best fit with female body attractiveness, and the effect of Volume-Height Index can be fitted with two half bell-shaped exponential curves with an optimal Volume-Height Index at 14.2 liter/m2. It is suggested that the general trend of the effect of Volume-Height Index may be culturally invariant, but the optimal value of Volume-Height Index may vary from culture to culture. In addition to Volume-Height Index, other body parameters or ratios which reflect body proportions and the traits of feminine characteristics had smaller but significant effects on female body attractiveness, and such effects were stronger at optimum Volume-Height Index.     

Ghosted?: Navigating strategies for reducing uncertainty and implications surrounding ambiguous loss

Ghosting is the unilateral dissolution process of ceasing communication through media. When ghosted, non‐initiators are often left without the ability to navigate the resulting uncertainty or impending dissolution processes. Utilizing uncertainty reduction theory and ambiguous loss, this investigation explores effective and ineffective strategies used to find answers, reduce uncertainty, and navigate post‐dissolution consequences. Employing two studies from Amazon's Mechanical Turk, a thematic analysis to delineate and affirm categories—7 effective and ineffective strategies and 11 categories of personal and relational implications after being ghosted—was used. These studies provide insight about non‐initiators process to resolve their uncertainty and highlight ramifications from ambiguity that non‐initiators experience after being ghosted. These findings discuss connections to knowledge acquisition, closure processing, and consequences of ghosting.
