高特质焦虑个体常表现出对威胁性刺激的选择性注意偏向的特点。然而其潜在的神经机制目前仍不清楚。通过记录高、低特质焦虑者各17名进行情绪加工时的ERP,比较了两组个体在选择性注意偏向发生的时间进程和相关的神经反应的差异。结果发现,高特质焦虑者诱发出更大的N1,进一步发现恐惧图片比中性图片诱发更大的N1;而低特质焦虑者诱发了更大的N2,特质焦虑得分越低, N2波幅越大。结果初步说明高特质焦虑者加工早期对恐惧图片分配了较多的注意资源,并且其抑制执行功能可能受损;而低特质焦虑者较晚开始区分恐惧图片和中性图片。这些结果提供了支持认知-动机模型的新证据。 相似文献

两个实验均以汉字为材料,采用2×3被试内设计,分别使用语义范畴判断和语音判断任务考察了汉字频率对阅读中情绪价效应的影响。结果发现:在语义任务中,情绪价与字频之间交互作用不显著,低频消极字和积极字的反应时均快于中性字,高频消极字的反应时也快于中性字,但高频积极字与中性字之间无差异。在语音任务中,情绪价与字频之间交互作用显著,低频消极字和积极字的反应时均快于中性字,而高频字的语音通达则不受情绪价的影响。汉字阅读中的情绪价效应不是自动化的过程,会受到字频与任务形式的影响。 相似文献

This study investigated both young men's and young women's perpetration of physical, sexual, and psychological forms of dating violence, examining predictors of violence including maternally or paternally perpetrated forms of various types of child maltreatment, as well as attitudes toward dating violence and dating violence victimization. Results of hierarchical linear regressions found that childhood experiences of maternal neglect predicted men's physical perpetration, and childhood sexual abuse predicted women's sexual perpetration and men's psychological perpetration. Further, positive attitudes toward dating violence predicted women's physical, psychological, and sexual perpetration, as well as men's sexual perpetration, and experiences of dating violence victimization were the strongest predictors of most forms of dating violence perpetration, particularly among women. Implications for future research and prevention initiatives are discussed. 相似文献

童年中期身体侵害、关系侵害与儿童的情绪适应 总被引:3,自引:3,他引:3
采用整群抽样法选取2603名小学儿童(平均年龄9.05 ± 0.53岁)作为被试,考察童年中期同伴侵害现象的基本特点,以及同伴侵害与情绪适应(孤独感、社交焦虑和抑郁)的关系。结果发现:(1)在性别差异方面,男生的身体侵害与关系侵害水平均显著高于女生,与身体侵害相比,关系侵害的性别差异程度较小。在同伴侵害的类型特点方面,儿童遭受身体侵害的水平显著高于关系侵害。(2)身体侵害、关系侵害与儿童的各情绪适应指标显著正相关,身体侵害和关系侵害能同时预测儿童的情绪适应不良;并且与身体侵害相比,关系侵害对情绪适应的影响更大。(3)身体侵害与社交焦虑的关系表现出性别差异,即身体侵害能预测女生的社交焦虑,而对男生的社交焦虑不存在预测作用;但同伴侵害与孤独感、抑郁的关系不受性别的调节。总体而言,有同伴侵害经历的男生和女生具有相似的情绪适应问题。 相似文献

Proponents of non-conceptual content have recruited it for various philosophical jobs. Some epistemologists have suggested
that it may play the role of “the given” that Sellars is supposed to have exorcised from philosophy. Some philosophers of
mind (e.g., Dretske) have suggested that it plays an important role in the project of naturalizing semantics as a kind of
halfway between merely information bearing and possessing conceptual content. Here I will focus on a recent proposal by Jerry
Fodor. In a recent paper he characterizes non-conceptual content in a particular way and argues that it is plausible that
it plays an explanatory role in accounting for certain auditory and visual phenomena. So he thinks that there is reason to
believe that there is non-conceptual content. On the other hand, Fodor thinks that non-conceptual content has a limited role.
It occurs only in the very early stages of perceptual processing prior to conscious awareness. My paper is examines Fodor’s
characterization of non-conceptual content and his claims for its explanatory importance. I also discuss if Fodor has made
a case for limiting non-conceptual content to non-conscious, sub-personal mental states.
This paper has grown out of comments I made on Fodor’s paper “Revenge of the Given,” delivered at The Steven Humphrey Excellence
in Philosophy Conference: “Content and Concepts: A Conference on the Philosophy of Mind” at the University of California,
Santa Barbara, February 14, 2004. Thanks to Jerry Fodor for useful feedback, and to Barry Loewer for discussing with me the
ideas that went into this paper. 相似文献

采用项目法定向遗忘研究范式,在两个实验中分别使用情绪性语词和图片材料,考察主观努力程度影响情绪材料定向遗忘的心理机制。研究采用2(语词或图片情绪效价:正词/负词)×2(指示符:记住/忘记)×3(努力程度:20%/60%/100%)的被试内设计,因变量为情绪性语词或图片的再认率和定向遗忘效应。结果表明,正效价词在三种努力程度忘记条件的再认率无差别,而越努力去忘记负效价词,反而越能记住;正负效价的图片材料都呈现出越努力去忘记反而越能记住的特点。以上结果表明,语词与图片分别适合有意识加工和无意识加工,记住指令导致对情绪性语词和图片的选择性复述,符合选择性复述/被动衰退理论,而不同努力程度的忘记指令又引发了对情绪性语词和图片的主动抑制,符合注意抑制/执行控制理论。 相似文献

Amnesic patients can re-experience emotions elicited by forgotten events, suggesting that brain systems for episodic and emotional memory are independent. However, the range of such emotional memories remains under-investigated (most studies employing just positive–negative emotion dyads), and executive function may also play a role in the re-experience of emotions. This is the first investigation of the intensity of the emotional re-experience of a range of discrete emotions (anger, fear, sadness, and happiness) for a group of amnesic patients. Twenty Korsakoff syndrome (KS) patients and 20 neurologically normal controls listened to four novel emotional vignettes selectively eliciting the four basic emotions. Emotional experience was measured using pen-and-paper Visual Analogue Mood Scales and episodic memory using verbal recollections. After 30 min, the recollection of stories was severely impaired for the patient group, but the emotional re-experience was no different from that of controls. Notably, there was no relationship between episodic recall and the intensity of the four emotions, such that even profoundly amnesic patients reported moderate levels of the target emotion. Exploratory analyses revealed negative correlations between the intensity of basic emotions and executive functions (e.g., cognitive flexibility and response inhibition) for controls but not patients. The results suggest that discrete emotions can be re-experienced independently of episodic memory, and that the re-experience of certain discrete emotions appears to be dampened by executive control. KS patients with absent or mild cognitive symptoms should benefit from emotion-regulation interventions aimed at reducing the recognized affective burden associated with their episodic memory deficit. 相似文献
