We demonstrated unconscious learning of task-irrelevant perceptual regularities in a Serial Reaction Time (SRT) task in both visual and auditory domains. Participants were required to respond to different letters (‘F’ or ‘J’, experiment 1) or syllables (‘can’ or ‘you’, experiment 2) which occurred in random order. Unbeknownst to participants, the color (red, green, blue or yellow) of the two letters or the tone (1–4) of the syllables varied according to certain rules. Reaction times indicated that people indeed learnt both the color and tonal regularities indicating that task-irrelevant sequence structure can be learned perceptually. In a subsequent prediction test of knowledge of the color or tonal cues using subjective measures, we showed that people could acquire task irrelevant knowledge unconsciously. 相似文献

评价中心是一种高保真度的情境模拟,它被设计用来在多种与工作相关的活动中测量多项维度.30年来的大量研究发现,评价中心具备良好的内容效度和效标关联效度,但构想效度却始终不理想,评价中心评分反映的总是由活动而非预先设想的维度带来的效应.这一评价中心“构想效度谜题”吸引了大量研究关注,并逐步形成了维度中心取向、活动中心取向及交互作用取向三种主要观点,分别主张控制各种误差因素以改善维度测量、放弃维度而转向活动或任务以及关注维度与活动的共同作用.未来研究应在传统的维度中心取向之外给予活动中心取向足够重视,并重点发展交互作用取向. 相似文献

本研究采用实验和问卷相结合的方法,探讨了愤怒和恐惧情绪及不同的方案数量对危机决策的影响,并分析了该效应的性别差异。研究结果表明:(1)恐惧情绪下被试的危机决策时间显著长于其在愤怒情绪下的危机决策时间,且情绪和性别变量在危机决策时间上存在显著的交互作用;(2)女性在恐惧情绪下的危机决策时间显著长于其在愤怒情绪下的危机决策时间,且显著地长于男性的危机决策时间。同时,男性对其危机决策的满意程度显著高于女性,且情绪变量和性别变量在危机决策自信程度指标上存在显著的交互作用;(3)随着方案数量的增加,尤其当方案数量为4时,被试的危机决策时间较其他两种情况显著增长。该研究结果可为各类突发性危机事件的管理与决策提供依据。 相似文献

旨在探讨不同刺激重复量对反应抑制后效应的影响。在不同刺激重复量条件下,让被试完成停止信号任务。结果发现,从总体来看,刺激重复量因素上的主效应显著,重复类型因素上主效应不显著;信号抑制条件下不同刺激重复量后无信号试次反应时与总的无信号试次反应时差异不显著;信号反应条件下不同刺激重复量后无信号试次反应时与总的无信号试次反应时差异显著。本研究表明不同刺激重复量条件下的反应抑制后效应是认知控制的执行加工而非自动化的记忆提取。 相似文献

Nongovernmental organizations (NGOs) serve Iraqis living in Jordan as “guests.” In 2008, 258 Jordanian humanitarian staff and Iraqi volunteers working for NGOs completed a needs assessment survey. Work characteristics, stressors, and support variables were evaluated regarding their influence on depression, anxiety, post-traumatic stress disorder (PTSD), and burnout through multivariate logistic regressions. There was a significant difference in depression, anxiety, and burnout across nationality. Traumatic exposure increased the risk for anxiety, depression, and PTSD. Working longer in the humanitarian sector was associated with less risk of anxiety and depression, and lower social support was a risk for anxiety. Managers were at higher risk for burnout, and low team cohesion was a risk for burnout. Implications for aid organizations are discussed. 相似文献

Four-, five-, and six-year-old Chinese and Canadian boys and girls were presented a series of 11 graphic models and were asked to draw them. Supporting Piaget's theory, the data indicated that drawing performance on the topological dimension was better than the performance on the Euclidean dimension, and that there were neither gender nor cultural differences in performance. The research offers strong support for a main effect of biological or maturational factors as the foundation for the developmental influences in the acquisition of spatial conceptions. 相似文献

When interacting with infants, human adults modify their behaviours in an exaggerated manner. Previous studies have demonstrated that infant‐directed modification affects the infant's behaviour. However, little is known about how infant‐directed modification is elicited during infant–parent interaction. We investigated whether and how the infant's behaviour affects the mother's action during an interaction. We recorded three‐dimensional information of cup movements while mothers demonstrated a cup‐nesting task during interaction with their infants aged 11 to 13 months. Analyses revealed that spatial characteristics of the mother's task demonstration clearly changed depending on the infant's object manipulation. In particular, the variance in the distance that the cup was moved decreased after the infant's cup nesting and increased after the infant's task‐irrelevant manipulation (e.g. cup banging). This pattern was not observed for mothers with 6‐ to 8‐month‐olds, who do not have the fine motor skill to perform the action. These results indicate that the infant's action skill dynamically affects the infant‐directed action and suggest that the mother is sensitive to the infant's potential to learn a novel action.

The present study aims to understand the mental health status of an understudied group of migrant children – children of migrant workers in China. A total of 1,466 children from Beijing participated in the study that compared migrant children (n = 1,019) to their local peers (n = 447) in public and private school settings. Results showed that overall, migrant children reported more internalizing and externalizing mental health problems and lower life satisfaction than local peers. However, public school attendance served as a protective factor for migrant children's mental health. The mental health status of migrant children attending public schools, including externalizing problems as well as friend and school satisfaction, was not different from local children. In addition, our data indicates that the protective effect of public school attendance for migrant children may be even more salient among girls than boys, and for younger children than older children. 相似文献

Understanding the Construct of Maximizing Tendency: A Theoretical and Empirical Evaluation

More attention is being given to the stable, dispositional tendency to maximize when making decisions. Within the growing body of research has been an exchange regarding the appropriate means of measuring maximizing tendency. Guided primarily by psychometric and statistical analyses, these studies have critiqued and revised existing maximizing tendency scales and/or introduced new measures. Importantly, many of these discussions seem to ignore theoretical considerations of the construct of maximizing. In this article, we revisit the original work of Herbert Simon, from where the theory of maximizing tendency was developed, and provide a theoretical account for how maximizers can be distinguished from satisficers and the implications therein for the measurement of maximizing tendency. Across two studies, we provide an updated psychometric, correlational, and behavioral comparison of the two most popular maximizing tendency scales: the Maximization Scale and the Maximizing Tendency Scale. Results demonstrate that the Maximizing Tendency Scale is more theoretically and psychometrically valid than the Maximization Scale. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
