Category norms as a function of culture and age: comparisons of item responses to 105 categories by american and chinese adults

Understanding how aging influences cognition across different cultures has been hindered by a lack of standardized, cross-referenced verbal stimuli. This study introduces a database of such item-level stimuli for both younger and older adults, in China and the United States, and makes 3 distinct contributions. First, the authors specify which item categories generalize across age and/or cultural groups, rigorously quantifying differences among them. Second, they introduce novel, powerful methods to measure between-group differences in freely generated ranked data, the rank-ordered logit model and Hellinger Affinity. Finally, a broad archive of tested, cross-linguistic stimuli is now freely available to researchers: data, similarity measures, and all stimulus materials for 105 categories and 4 culture-by-age groups, comprising over 10,000 fully translated unique item responses.     

Average-KR schedule benefits generalized motor program learning

The main purpose of this study was to examine the effects of average Knowledge of Results (KR) on generalized motor program learning and parameter learning. Two groups of participants (n = 15 per group) performed 80 acquisition trials of sequential timing tasks. All participants were asked to depress sequentially four keys (2, 4, 8, and 6) on the numeric pad portion of the computer keyboard with the index finger of the right hand. The author presented average feedback on timing errors based on 5-trial blocks and compared this feedback schedule with every-trial feedback. Analysis of the delayed no-feedback retention test indicated a strong advantage for the average KR compared with the every-trial condition in both generalized motor program learning and parameter learning. The current results suggest that the average KR schedule may have positive effects on generalized motor program learning and parameter learning.     

家人情感卷入对老年自我刻板印象的影响：基于潜变量增长模型的分析

本研究使用问卷法对257名老年人进行了历时1年的3次追踪测试, 采用潜变量增长模型与交叉滞后回归分析考察了家人情感卷入与老年自我刻板印象的变化趋势, 家人情感卷入发展与老年自我刻板印象发展的关系, 以及家人情感卷入对老年自我刻板印象的时序效应。结果发现：(1)老年人感知到的家人情感卷入在1年内呈线性递减, 而老年自我刻板印象呈线性增长; (2)家人情感卷入的初始水平负向预测老年自我刻板印象的初始水平与增长速率; (3)家人情感卷入的下降速率也显著预测了老年自我刻板印象的增长速率; (4)交叉滞后回归分析进一步支持了老年人家人情感卷入对老年自我刻板印象的总体负向预测作用。本研究为老年刻板印象内化的家庭过程提供了理论支持, 并对减少老年刻板印象内化、改善消极老年自我刻板印象的干预具有一定的实践价值。     

自我损耗对攻击行为的影响:复愈性环境的作用

本研究采用实验(stroop任务和竞争反应时任务)和问卷(积极情感消极情感量表)相结合的方法,探讨复愈性环境对自我损耗后攻击性行为的影响。结果发现:高损耗组反应性攻击行为显著大于低损耗组,两组主动性攻击行为差异不显著;观看复愈性环境和非复愈性环境后,复愈性环境组反应性攻击行为显著低于非复愈性环境组,主动性攻击行为两组无差异。结果表明:自我损耗后会产生情绪上的不良表现,反应性攻击行为增多,而主动性攻击行为不受损耗影响;自我损耗后观看复愈性环境,能够缓解情绪上的不良表现,增加认知资源,从而减少攻击行为。     

Using a Kinect sensor to acquire biological motion: Toolbox and evaluation

Biological motion (BM) is the movement of animate entities, which conveys rich social information. To obtain pure BM, researchers nowadays predominantly use point-light displays (PLDs), which depict BM through a set of light points (e.g., 12 points) placed at distinct joints of a moving human body. Most prevalent BM stimuli are created by state-of-the-art motion capture systems. Although these stimuli are highly precise, the motion capture system is expensive and bulky, and its process of constructing a PLD-based BM is time-consuming and complex. These factors impede the investigation of BM mechanisms. In this study, we propose a free Kinect-based biological motion capture (KBC) toolbox based on the Kinect Sensor 2.0 in C++. The KBC toolbox aims to help researchers acquire PLD-based BM in an easy, low-cost, and user-friendly way. We conducted three experiments to examine whether KBC-generated BM can genuinely reflect the processing characteristics of BM: (1)?Is BM from this source processed globally in vision? (2)?Does its BM (e.g., from the feet) retain detailed local information? and (3)?Does the BM convey emotional information? We obtained positive results in response to all three questions. Therefore, we think that the KBC toolbox can be useful in generating BM for future research.     

Effects of perceptual and conceptual similarities on consumers' evaluations of copycat brand names

Copycats often choose brand names that mimic perceptual, conceptual, or both elements of leading brand names. Yet little is known about how perceptual and conceptual similarities of a copycat interact to affect consumers' evaluations, especially in logographic language systems (e.g., Chinese). Three laboratory experiments demonstrate that perceptual similarity alone leads to negative evaluations of copycat brand names; this negative effect, however, can be mitigated when conceptual similarity is added. The underlying mechanism for this effect can be traced to consumers' persuasion knowledge. Perceptual (vs. conceptual) similarity activates consumers' persuasion knowledge about the insincere motives of the copycat brand, which in turn shapes their brand evaluations. However, this effect can become less prominent when conceptual similarity is added because it alleviates use of persuasion knowledge, or when a consumer is in a happy mood because it neutralizes persuasion knowledge. These findings shed light on how different types of copycat strategies interact to affect copycat brand name evaluations and offer important implications for marketing practice.

负启动效应的认知神经科学研究

近几年,对负启动效应的神经机制研究发现,干扰项抑制与情节提取都是引起负启动的原因,究竟哪种机制起主要作用与实验任务有很大的关系。从现有的研究结果来看,位置负启动与前额皮层有关,EPR上表现为P1和N1波幅减小或N2波幅的增大,支持抑制机制。特性负启动P3成分仍存在不一致的结果,脑区的广泛激活模式使得研究者越来越倾向采取整合的观点。
