A laboratory experiment contrasting disabled and non-disabled job applicants assessed the impact of disability type, physical attractiveness, and proximity of the job opening to the decision maker. Physically disabled applicants were rated higher than either non-disabled or mentally disabled applicants. However, some evidence was found of a bias against disabled applicants, particularly the mentally disabled, when the position involved was in close proximity to the decision maker. 相似文献

采用启动条件下的词汇命名和图片命名范式, 探讨在汉语言语产生中词长效应的产生机制, 考察概念激活、词条提取和语音编码对词长效应的影响。实验1和实验2表明, 词条提取过程并不影响在词汇命名中的词长效应, 支持多词素词整词通达表征的理论。实验3显示, 概念激活和语音编码共同影响在图片命名中的词长效应, 被试对长词的命名时间显著地长于对短词的命名时间, 对下属水平概念的词汇提取显著地慢于对基本水平概念的词汇提取。研究结果支持多词素词语音编码的序列性和基本水平类别优先习得的观点。 相似文献

视角效应(Perspective Effects)是指四卡问题解决中,当被试从不同的角度对条件规则进行检验时,其选择偏向会在卡片p,q和-p,q之间发生稳定变化的现象。视角效应对四卡问题的解决有重要影响,但其存在条件及发生机制仍存在争议。本研究通过3个实验,探讨四卡问题中的视角效应。实验1和实验2采用混合实验设计,结果表明,转换社会契约、因果规则的四卡问题中,发现视角效应,抽象规则中,提供反例比提供充分必要条件更有利于产生视角效应。实验3在不同视角下研究四卡问题与条件推理的关系。结果表明,四卡问题与条件推理之间不具有逻辑一致性,产生分离现象。总之,视角效应在抽象规则和特定规则中均存在,而提供反例更有利于视角效应的产生。领域一般性或领域特殊性均不能有效解释视角效应的产生,两种机制的综合调节为解释视角效应提供新的角度。 相似文献

以46名大学生为被试,利用“九洞仪”创设实验室压力情境,考察不同心理一致感个体压力情境下的情绪反应及恢复特点。结果表明:(1)压力情境下,高、低心理一致感个体的情绪反应存在显著性差异。高心理一致感个体出现较多的积极情绪,低心理一致感个体则以消极情绪体验为主。(2)低心理一致感压力情境诱发出的消极情绪显著多于积极情绪,消极情绪的诱发量较大。(3)压力任务后,高心理一致感个体在情绪恢复量上显著多于低心理一致感个体,心理健康的自我康复力较大。(4)压力任务前后,低心理一致感个体的消极情绪诱发量显著高于恢复量,在消极情绪变化上表现出“诱发多,恢复少”的特点。 相似文献

在有多种解题策略的认知诊断问题情境中, 用每个Q矩阵表示一种解题策略, 由此将单策略认知诊断RRUM模型拓广为多策略RRUM模型(MS-RRUM)。随后, 在应用MS-RRUM模型的CD-CAT中开发了适用于多策略情境的MAP参数估计法和多策略香农熵(MSSHE)选题法。将MSSHE选题法与随机选题法分别在不同属性数量、不同测验长度下进行比较, 结果发现前者对被试的策略和认知状态判准率都显著优于后者, 而且都很理想。这样就顺利实现了在CD-CAT做策略诊断的目标。 相似文献

Black, Asian, and White participants (N = 210) created self-resembling avatars and engaged in peer-selection tasks during social events in the virtual world, Second Life, that were designed to simulate various types of resource competition. Participants in merit-based resource competition settings had less diversity in their peer groups compared to participants in settings where no resource competition was present, and Asian participants had lower preference for Black peers. Furthermore, these relationships were mediated by out-group discomfort. Results are discussed in relation to partial support for triangulated threat theory of group relations among Blacks, Asians, and Whites. 相似文献

Long-range autocorrelations (LRA) are a robust feature of rhythmic movements, which may provide important information about neural control and potentially constitute a powerful marker of dysfunction. A clear difficulty associated with the assessment of LRA is that it requires a large number of cycles to generate reliable results. Here we investigate how series length impacts the reliability of LRA assessment. A total of 94 time series extracted from walking or cycling tasks were re-assessed with series length varying from 64 to 512 data points. LRA were assessed using an approach combining the rescaled range analysis or the detrended fluctuation analysis (Hurst exponent, H), along with the shape of the power spectral density (α exponent). The statistical precision was defined as the ability to obtain estimates for H and α that are consistent with their theoretical relationship, irrespective of the series length. The sensitivity consisted of testing whether significant differences between experimental conditions found in the original studies when considering 512 data points persisted with shorter series. We also investigate the use of evenly-spaced diffusion plots as a methodological improvement of original version of methods for short series. Our results show that the reliable assessment of LRA requires 512 data points, or no shorter than 256 data points provided that more robust methods are considered such as the evenly-spaced algorithms. Such series can be reasonably obtained in clinical populations with moderate, or even more severe, gait impairments and open the perspective to extend the use of LRA assessment as a marker of gait stability applicable to a broad range of locomotor disorders. 相似文献

In this study, we investigated age differences in situation selection to understand the role stimulus arousal plays in motivating age differences in this type of emotion regulation. Participants freely selected from a set of affective videos using information about the valence and arousal of each stimulus. There were age differences both in the valence and arousal of selected stimuli. Older adults selected more neutral and low-arousal stimuli while younger adults selected more negative and high-arousal stimuli. We consider these results in light of recent theoretical models and conclude that studies of age differences in emotion regulation must consider both valence and arousal. 相似文献
