Stroke is the main cause of acquired disability in adults, and specific deficits in working memory (WM) are among the most common cognitive consequences. In neuropsychological routine, WM is most of the time investigated in the framework of the multicomponent model (Baddeley & Hitch, 1974, The psychology of learning and motivation, 47). Using a more recent theoretical WM model, the time-based resource-sharing (TBRS) model (Barrouillet et al., 2011, Psychol. Rev., 118, 175), the aim of the present study was to investigate in young post-stroke patients to which extent attentional maintenance is impaired in WM. To address this question, we discarded other factors known to directly influence WM performance, that is processing speed and short-term memory span. We proposed to 53 post-stroke patients and to 63 healthy controls a complex span paradigm in which participants were asked to alternate between the memorization of a series of images and a concurrent parity judgement task of a series of digits. To investigate the attentional maintenance processes, we manipulated the cognitive load (CL) of the concurrent task. CL effect is typically interpreted as the involvement of attentional maintenance processes. The task was adapted to each participant according to their processing speed and memory span. As expected, the results showed higher recall performance in healthy controls compared with post-stroke patients. Consistent with the literature, we also observed higher performance when the CL was low compared with high. However, the improvement in recall at low CL was smaller for post-stroke patients compared with controls, suggesting that post-stroke WM deficit could be in part due to a deficit of the attentional maintenance processes. 相似文献

生活中, 个体会时时关注自己的行为结果并及时做出调整以适应环境的变化。但在应激下个体能否有效地监控行为并做出适应性调整依然未知。本研究招募了52名男性大学生被试, 将其随机分入应激组与控制组, 采用特里尔社会应激测试(Trier Social Stress Test, TSST)诱发个体的应激反应, 并结合错误意识任务(Error Awareness Task, EAT)探索个体急性应激下的错误监控与错误后调整过程。应激指标的结果显示应激组个体在应激任务后唾液皮质醇、心率、应激感知自我报告和负性情绪均显著高于控制组, 表明急性应激的诱发是成功的。行为结果显示应激组的错误意识正确率显著低于控制组, 错误意识反应时显著短于控制组; 进一步地, 应激组个体在意识到错误之后的试次上正确率显著低于未意识到错误之后的试次, 并且应激组个体在意识到错误之后的试次上正确率低于控制组。结果表明急性应激降低了个体对错误反应的监控水平, 即便在辨别出错误反应的情况下, 个体的行为监控与调节也更差。本研究说明急性应激会损伤行为监控系统, 导致个体的行为适应性下降。 相似文献

采用道德困境判断的CNI(consequence, norm, inaction)模型,通过两个实验考察权力感对道德困境判断的影响。实验1探讨个人权力感对道德困境判断的影响,结果显示高个人权力感显著增加被试对规则的敏感,促使个体做出道义论的道德判断。实验2考察回忆任务启动的权力感对道德困境判断的影响,发现相对于低权力感启动的被试,高权力感启动的被试在进行判断时更关注行为的结果,对规则更不敏感,这说明启动的权力感促进功利主义的道德判断,抑制道义论的道德判断。结果表明,不同类型的权力感对道德困境判断的影响存在差异。 相似文献

ICAP is a theory of active learning that differentiates students’ engagement based on their behaviors. ICAP postulates that I nteractive engagement, demonstrated by co‐generative collaborative behaviors, is superior for learning to C onstructive engagement, indicated by generative behaviors. Both kinds of engagement exceed the benefits of A ctive or P assive engagement, marked by manipulative and attentive behaviors, respectively. This paper discusses a 5‐year project that attempted to translate ICAP into a theory of instruction using five successive measures: (a) teachers’ understanding of ICAP after completing an online module, (b) their success at designing lesson plans using different ICAP modes, (c) fidelity of teachers’ classroom implementation, (d) modes of students’ enacted behaviors, and (e) students’ learning outcomes. Although teachers had minimal success in designing Constructive and Interactive activities, students nevertheless learned significantly more in the context of Constructive than Active activities. We discuss reasons for teachers’ overall difficulty in designing and eliciting Interactive engagement. 相似文献

An emerging literature indicates that dispositional bias in causal attribution of social behavior is weaker for people with working-class (vs. middle-class) backgrounds. However, it is unknown whether this difference is also present in spontaneous forms of trait inference. In the current work, American undergraduates were asked to merely memorize many pairings of a target face and a trait-implying behavior. In a subsequent lexical judgment task, after each face was presented as a fixation, either an implied trait or its antonym was given as a target. As expected, participants with college-educated parents (middle class) showed a strong N400 event-related potential component to the antonym (vs. the implied trait), suggesting spontaneous trait inference during the memorization phase. In contrast, those with high-school-educated parents (working class) showed no such effect. It is important to note that the N400 spontaneous trait inference effect was associated with perceived significance of dispositions in accounting for social behaviors. 相似文献

作为两种常见且易被混淆的自我意识情绪, 诸多研究者对内疚和羞耻的产生前因及影响后效进行研究, 尤其是近年来的研究逐渐关注两者对合作行为的影响。我们通过对已有研究进行梳理发现, 内疚和羞耻对合作行为的影响及其机制存在差异, 内疚的影响更为稳定及具有普适性, 羞耻的影响具有复杂性和多样性, 更容易受到其他因素的影响。内疚和羞耻对合作行为的不同影响可从动机机制和调节机制两方面进行解释。首先, 动机机制包括内疚对他人的补偿、修复动机以及羞耻对自我的保护、修复动机。内疚对他人的补偿、修复动机主要体现在维护社会互动中的公平; 弥补对他人造成的伤害, 降低自己和他人的痛苦; 修复人际关系, 重新获得他人或自己的接纳与认同。羞耻对自我的保护、修复动机主要体现在释放消极的情绪状态; 维护积极的自我形象和声誉, 修复自我; 保护自我, 防止后续伤害及不良后果。总体而言, 内疚者关注过失行为及后果, 侧重于对受害他人的补偿或对与他人关系的修复, 而羞耻者关注整体自我的受损, 侧重于对自我的保护和对自己社会形象的修复, 基于此, 我们在前人研究的基础上构建了内疚与羞耻影响合作行为的动机机制对比模型图。其次, 调节机制涉及到个体因素和情境因素的调节作用, 其中个体因素包括认知因素、社会价值取向、自我控制能力、情绪特质和情绪状态, 情境因素包括暴露情境和掩蔽情境、实验情境和日常情境、相关情境和不相关情境。具体而言, 内疚对合作行为的影响的较少受情境的限制, 而羞耻受情境因素限制较多, 在暴露情境、相关情境中更能促进合作行为的产生, 而在掩蔽情境、不相关情境中, 羞耻较难影响个体的合作抉择, 且无论是实验室情境还是日常情境, 内疚似乎都比羞耻更易影响合作。最后, 鉴于内疚与羞耻的诱发和测量方法的有效性仍需检验, 两种情绪对合作行为影响的过程机制和生理机制仍不明晰, 个体因素影响的研究尚不充足以及跨文化研究较为缺乏, 未来研究可以从内疚和羞耻诱发与测量方法的有效性, 情绪作用发生的内在过程和生理机制, 情绪影响的个体和文化差异这几方面进行扩展和深挖。 相似文献

采用概念判断任务,通过两个递进式实验探索控制感剥夺对状态毅力的影响并考察趋近动机在其中的作用。实验1主观报告结果显示:短时条件下,控制感剥夺组的状态毅力显著高于控制感维持组,尤其表现在努力持续性维度;长时条件下,两组差异不显著。实验2在此基础上加入行为指标结果显示:短时控制感剥夺通过高趋近动机对状态毅力产生影响。结果表明毅力是可塑的,突出表现在努力持续性上,该效应出现在个体经历短时控制感剥夺后。 相似文献

In this study, the Perceived Perfectionism from God Scale (PPGS) was developed with Latter-day Saints (Mormons) across two samples. Sample 1 (N = 421) was used for EFA to select items for the Perceived Standards from God (5 items) and the Perceived Discrepancy from God (5 items) subscales. Sample 2 (N = 420) was used for CFA and cross-validated the 2-factor oblique model as well as a bifactor model. Perceived Standards from God scores had Cronbach alphas ranging from .73 to .78, and Perceived Discrepancy from God scores had Cronbach alphas ranging from .82 to .84. Standards from God scores were positively correlated with positive affect, whereas Discrepancy from God scores was positively correlated with negative affect, shame and guilt. Moreover, these two PPGS subscale scores added significant incremental variances in predicting associated variables over and above corresponding personal perfectionism scores. 相似文献
