The missing link between faces and names: Evidence from Alzheimer's disease patients

Retrieval of proper names is a cause of concern and complaint among elderly adults and it is an early symptom of patients suffering from neurodegenerative diseases such as Alzheimer's disease (AD). While it is well established that AD patients have deficits of proper name retrieval, the nature of such impairment is not yet fully understood. Specifically, it is unknown whether this deficit is due to a degradation of the links between faces and proper names, or due to deficits in intentionally accessing and retrieving proper names from faces. Here, we aim to investigate the integrity of the links between famous faces and proper names in AD while minimizing the impact of the explicit retrieval. We compare the performances of AD patients and elderly controls in a face-name priming task. We assess the integrity of the link between faces and names at two different levels: identity level - the name and face belong to the same person; and semantic level - the name and face belong to the same category (e.g., politicians). Our results reveal that AD patients compared with controls show intact semantic priming but reduced priming for person identity. This suggests that the deficits in intentionally retrieving proper names in AD are the result of a partial disruption of the network at the identity level, i.e., the links between known faces and proper names.     

Can the Media Help Women Be Better at Math? Stereotype Threat,Selective Exposure,Media Effects,and Women's Math Performance

This study examines women's media selections when under the gender–math stereotype threat and the subsequent media effects on their math performance through the lens of the Selective Exposure Self‐ and Affect‐Management (SESAM) model, mood management theory, and social comparison theory. Female college students were randomly assigned to the stereotype threat condition or the control condition; then, they selectively browsed magazine pages showing female role models in stereotypical domains (beauty or family) and counterstereotypical domains (career or science) before taking the math test. The results show that women spent more time on career magazines when under threat, and this selective exposure's effect on their math performance was moderated by their assimilation to the role models.     

义符启动范式下义符的语义和语法激活的时间进程

采用义符启动范式,探讨义符的语义、语法信息的激活进程。结果表明,就义符总体而言,义符的语义激活从启动早期一直持续到启动晚期,义符的语法信息未见有激活。然而,对不成字义符和成字义符分析发现,不成字义符和成字义符的语义、语法激活存在着差异。不成字义符的语义激活只在启动中期出现,语法信息则未见有激活;成字义符的语义信息一直处于激活状态,并且在启动晚期,语法信息也得到了激活。义符的语义、语法信息的激活进程和顺序是由义符的功能决定的。     

阈下安全启动改善非安全依恋女性的注意加工

研究采用掩蔽启动范式，结合事件相关电位技术，考察阈下安全启动在非安全依恋女性对婴儿面孔注意加工上的改善效应。行为指标上，悲伤程度评分和反应时结果均表明了安全启动的改善作用。ERP结果上，在早期注意加工阶段，阈下安全启动比中性启动诱发了依恋焦虑和依恋回避女性对婴儿面孔表情更大的N1波幅以及更优的P2潜伏期，在晚期控制注意加工相关的P3波幅上同样发现了类似的改善效应。研究结果表明阈下安全启动能够提升非安全依恋女性对婴儿面孔的知觉敏感性，改善非安全依恋女性注意加工缺陷，且这种改善效应不仅仅作用于早期注意加工阶段而且还可以扩展到个体有意识的晚期控制加工阶段。     

The role of inhibitory control in the development of analogical reasoning: From general to specific

This study examined the role of inhibitory control in the development of analogical reasoning using inter-task priming paradigms. In Experiment 1, 25 seven-year-olds, 27 nine-year-olds, and 27 adults completed Stroop tasks, which activated general inhibitory control ability, before analogical reasoning tasks. Children and adults performed faster on analogical reasoning tasks when they were primed by Stroop tasks. This priming effect was found to be stronger in children than in adults. In Experiment 2, 25 seven-year-olds, 28 nine-year-olds, and 28 adults completed relative number matching tasks, a more task-relevant inhibitory control task, before analogical reasoning tasks. The children and adults performed faster on analogical reasoning tasks when primed by relative number matching tasks. The priming effect was greater in seven-year-olds than in nine-year-olds and was greater in nine-year-olds than in adults. Thus, inhibitory control, whether assessed with general or specific tasks, played a priming role in analogical reasoning.
