摘要 本研究采用事件相关电位(ERP)技术,通过测量由视觉诱发的脑电成分晚正波(LPP)来比较情绪调节策略在生理电特征上的差异,进一步探讨认知重评和表达抑制的优劣。实验结果表明:(1)从波幅的角度来比较:在400-600ms时间窗口内,认知重评条件下恐怖图片诱发的LPP波幅显著小于在自由观看条件下的波幅,而表达抑制和自由观看组所诱发的LPP波幅差异较小。(2)从时间进程的角度来比较:认知重评与自由观看组的差异发生在400ms并持续到600ms,甚至以后;而表达抑制和自由观看之间的差异发生在450ms但是只持续到550ms。这表明认知重评相较于表达抑制,对负性情绪起调节作用开始较早,并且持续时间较长。这为认知重评优于表达抑制策略提供了神经生理学上的证据。 相似文献

Abstract. Making sense of soul and Sabbath necessitates understanding these phenomena experientially and then suggesting "biochemical" or empirical analogues. Soul, which is defined as the core or essence of a person (or group), includes a working memory of personally purposeful behavior. The states of the soul are reflected in the states of the mind and their physiological correlates-the states of the brain. Such uniqueness appears similar to the biblical cycle of creation-Sabbath-consciousness and its analogue in the biorhythm of brain-mind-that is, waking and work, sleeping and rest, dreaming (rapid eye movement [REM]) and the reorganization-integration process that is ever making sense of our senses by synthesizing what they mean to us. Working memory and biorhythm, therefore, are crucial for the making of meaning, and meaning is the making of soul. 相似文献

When is one head better than two? Interdependent information in group decision making 总被引:1,自引:0,他引:1
Research on information exchange in group decision making has frequently assumed that information items have independent meanings. Relaxing this assumption raises new issues and presents new possibilities. In the experiment presented here, dyads worked on hidden profile decision tasks in which pairs of unshared information items had interdependent meanings. Dyad decisions were more likely to be accurate when each pair of interdependent items was allocated to a single member (a “connected” hidden profile) than when each pair of interdependent items was separated between the two members (a “disconnected” hidden profile). These information distributions influenced the degree to which dyads considered unshared information. Cognitive load was manipulated, and it impaired decision makers’ ability to identify connections among interdependent information items. The differentiated distribution of information inherent in transactive memory systems moderated the negative effects of cognitive load on dyad decisions. 相似文献

Wandering is a difficult-to-manage behavior problem for individuals with cognitive impairments that can jeopardize safety if an individual enters a hazardous area or becomes lost. This study investigated the effects of a cloth barrier on entry into an unsafe area. The cloth barrier reduced entry into the restricted area and had high treatment acceptability. 相似文献

Research examining both the organizing and activating effects of testosterone in one-shot bargaining contexts has been vexed by inconsistencies. Some research finds that high-testosterone men are more likely to reject unfair offers in an ultimatum game and exogenous administration of testosterone to men leads to less generous offers. In contrast, other research finds that higher prenatal exposure to testosterone predicts more generous dictator game offers and administering testosterone to women leads to more generous ultimatum game offers. The current research seeks to resolve these inconsistencies by examining how the organizing effects of testosterone affect bargaining behavior. Because testosterone is associated with status seeking and concerns with social reputation, we hypothesized that testosterone would predict aggressive bargaining but only after provocation. Two studies found that prenatal testosterone exposure, as measured by 2D:4D ratio, led to aggressive responses for both males and females, but only after they received unfair offers. Furthermore, perceptions of fairness violations moderated but did not mediate the effect of testosterone on retributional responding. These results suggest that the organizing effects of testosterone have consistent effects on bargaining behavior for both males and females but its predictive ability requires some form of provocation to emerge. 相似文献

The autobiographical Implicit Association Test (aIAT) is a method that accurately identifies which one of two contrasting autobiographical events is true for the subject. The aIAT indexes the real autobiographical event (e.g. I was in Paris for Christmas) on the basis of the facilitating effect because it maps the real autobiographical event with true sentences (e.g. I am in front of a computer) on the same motor response. In this paper we focus on the conditions under which the autobiographical IAT accurately and reliably identifies autobiographical memories. A recent study showed a reduction in the accuracy of the aIAT when negative sentences are used. We have investigated the detrimental effect on aIAT accuracy of such negative sentence items, used to describe autobiographical events, compared with affirmative sentence items. While we highlight the reliability of the results obtained using negative sentences, we also show that the use of affirmative sentences in describing autobiographical events guarantees high accuracy and reliability of results in identifying the true autobiographical event. Finally, we summarise the criteria for preparing stimuli for an effective aIAT in order to maximise correct classifications of individual subjects. 相似文献

A little more than 40 years ago, J. R. Simon and colleagues introduced what is now called the Simon task, which yielded a correspondence effect known as the Simon effect. In this paper, I set Simon's contribution in the context of research on stimulus-response compatibility. The novel contribution of the Simon task is described, along with foundational findings using the task that Simon and colleagues reported. I acknowledge the significance of Simon's (1990) review chapter in generating my own interests in the Simon task and describe four selected lines of research from my lab that have been a result of those interests. The article concludes with a brief tribute to Simon and his contribution to experimental psychology. 相似文献

The development of number processing is generally studied by examining the performance on basic number tasks (comparison task, same-different judgment, and priming task). Using these tasks, so-called numerical distance effects are obtained. All these effects are generally explained by assuming a magnitude representation related to a mental number line: magnitudes are represented from left to right with partially overlapping representations for nearby numbers. In this study, we compared the performance of adults on these different tasks using non-symbolic stimuli. First, we investigated whether the effects obtained in these behavioral tasks are reliable. Second, we examined the relation between the three different effects. The results showed that the observed effects in the case of the comparison task and the same-different task proved to be reliable. The numerical distance effect obtained in the priming task, however, was not reliable. In addition, a correlation was found between the distance effects in the comparison task and the same-different task. The priming distance effect did not correlate with the other two effects. These results suggest important differences between distance effects obtained under automatic and intentional task instructions regarding the use of them as indices of mathematical ability. 相似文献

This article reports a meta-analysis comparing the size of repetition priming in full and divided-attention (DA) conditions. The main analysis included 38 effect sizes (ES) extracted from 21 empirical studies, for a total of 2074 (full-attention) and 2148 (divided-attention) participants. The mean weighted ES was 0.357 (95% CI = 0.278–0.435), indicating that divided attention produced a small, but significant, negative effect on implicit memory. Overall, the distinction between identification and production priming provided the best fit to empirical data (with the effect of DA being greater for production tests), whereas there was no significant difference between perceptual and conceptual priming. A series of focused contrasts suggested that word-stem completion might be influenced by lexical–conceptual processes, and that perceptual identification might involve a productive component. Implications for current theories of implicit memory are discussed. 相似文献
