Facial expressions of emotion involve a physical component of morphological changes in a face and an affective component conveying information about the expresser’s internal feelings. It remains unresolved how much recognition and discrimination of expressions rely on the perception of morphological patterns or the processing of affective content. This review of research on the role of visual and emotional factors in expression recognition reached three major conclusions. First, behavioral, neurophysiological, and computational measures indicate that basic expressions are reliably recognized and discriminated from one another, albeit the effect may be inflated by the use of prototypical expression stimuli and forced-choice responses. Second, affective content along the dimensions of valence and arousal is extracted early from facial expressions, although this coarse affective representation contributes minimally to categorical recognition of specific expressions. Third, the physical configuration and visual saliency of facial features contribute significantly to expression recognition, with “emotionless” computational models being able to reproduce some of the basic phenomena demonstrated in human observers. We conclude that facial expression recognition, as it has been investigated in conventional laboratory tasks, depends to a greater extent on perceptual than affective information and mechanisms. 相似文献

结合掩蔽启动范式和Go-Nogo范式,考察了任务设置影响负相容效应的机制。实验中以指向左或右的双箭头为掩蔽启动项,在两个Block中的Go试次中分别以箭头和汉字为目标项,要求被试对箭头或汉字做辨别反应,Nogo试次中不呈现目标项,被试无需反应。结果发现:Go试次中,只有在箭头任务设置下才出现负相容效应,脑电结果表现为一致条件下P3潜伏期显著长于不一致条件;Nogo试次中,箭头任务设置下的P3波幅显著大于汉字任务设置下的P3波幅。说明负相容效应受到任务设置这种自上而下认知控制过程的影响,且这种影响发生在阈下启动信息加工阶段。支持注意敏化模型,提示可以在更普遍的角度上理解负相容效应。 相似文献

Recent research has shown that memory illusions can successfully prime both children's and adults' performance on complex, insight-based problems (compound remote associates tasks or CRATs). The current research aimed to clarify the locus of these priming effects. Like before, Deese–Roediger–McDermott (DRM) lists were selected to prime subsequent CRATs such that the critical lures were also the solution words to a subset of the CRATs participants attempted to solve. Unique to the present research, recognition memory tests were used and participants were either primed during the list study phase, during the memory test phase, or both. Across two experiments, primed problems were solved more frequently and significantly faster than unprimed problems. Moreover, when participants were primed during the list study phase, subsequent solution times and rates were considerably superior to those produced by those participants who were simply primed at test. Together, these are the first results to show that false-memory priming during encoding facilitates problem-solving in both children and adults. 相似文献

以镶嵌残疾人图片的正性行为描述性信息为文本阅读材料,以大学生为被试,采用概念启动范式,考察了健全人对残疾人态度改善的可能性.研究结果表明,阅读残疾人正性行为描述性材料不仅可以降低健全人对残疾人的负性认知评价,而且可以提高其对残疾人的钦佩感和减弱其对残疾人的嫌弃感,同时也可提高健全人对该类人群的积极趋近行为和减弱对该类人群的消极趋近和消极回避行为,从而证明基于文本阅读的间接接触可改善公众对残疾人的负性态度的假设.因此,创造条件鼓励残疾人尽力发挥其积极的社会功能,引导和塑造其身残志不残的品质,有助于改善健全人对该类人群的消极态度. 相似文献

The sense of control over the consequences of one’s actions depends on predictions about these consequences. According to an influential computational model, consistency between predicted and observed action consequences attenuates perceived stimulus intensity, which might provide a marker of agentic control. An important assumption of this model is that these predictions are generated within the motor system. However, previous studies of sensory attenuation have typically confounded motor-specific perceptual modulation with perceptual effects of stimulus predictability that are not specific to motor action. As a result, these studies cannot unambiguously attribute sensory attenuation to a motor locus. We present a psychophysical experiment on auditory attenuation that avoids this pitfall. Subliminal masked priming of motor actions with compatible prime–target pairs has previously been shown to modulate both reaction times and the explicit feeling of control over action consequences. Here, we demonstrate reduced perceived loudness of tones caused by compatibly primed actions. Importantly, this modulation results from a manipulation of motor processing and is not confounded by stimulus predictability. We discuss our results with respect to theoretical models of the mechanisms underlying sensory attenuation and subliminal motor priming. 相似文献

Research into the perceived restorativeness of environments tends to focus on the Kaplans' Attention Restoration Theory at the expense of the affective considerations of Ulrich's psychoevolutionary model. To better understand the role of emotion, this study used contextual text‐based primers (newspaper articles) to manipulate participants' affective state (positive or negative) prior to them rating different environments using the Restorative Components Scale. Sixty‐nine participants completed the web‐based study, being pseudo‐randomly allocated to the positive‐ or negative‐prime condition before rating three natural and three urban environments. Natural environments were rated as more restorative than urban, with negative‐priming giving higher mean ratings for all environments. This effect was overall statistically significant for two components (Being Away and Fascination), but only Fascination showed a significant interaction of affective‐prime and environment, a larger effect being seen for natural environments. Results are discussed in terms of current understanding of the interrelationship between attentional and affective processes. 相似文献

Three experimental studies (N = 286) tested how priming the concepts of sex or romance influence the way people perceive other social media users. Participants first completed a word-search task containing sexual (intercourse, lust), romantic (love, heart), or control words. Participants then evaluated a target’s sexual qualities and romantic qualities based on social media profiles, as well as rated their acceptance of the priming stimuli. Results suggested that sex primes led participants to judge targets as being more alluring, racy, and provocative, whereas romance primes led participants to judge targets as being more tender, sentimental, and kind. Both men and women found all primes to be equally acceptable content; women were not averse to these mainstream, non-explicit sexual stimuli. Findings are discussed in terms of viewing sex and romance as distinct, yet related networks of concepts and the need to disentangle sex, romance, and sexualized views of romance. 相似文献

Studies comparing personality across cultures have found inconsistencies between self‐reports and measures of national character or behaviour, especially on evaluative traits such as Conscientiousness. We demonstrate that self‐perceptions and other‐perceptions of personality vary with cultural mindset, thereby accounting for some of this inconsistency. Three studies used multiple methods to examine perceptions of Conscientiousness and especially its facet Competence that most characterizes performance evaluations. In Study 1, Mainland Chinese reported lower levels of self‐efficacy than did Canadians, with the country effect partially mediated by Canadian participants' higher level of independent self‐construal. In Study 2, language as a cultural prime induced similar effects on Hong Kong bilinguals, who rated themselves as more competent and conscientious when responding in English than in Chinese. Study 3 demonstrated these same effects on ratings of both self‐perceived and observer‐perceived competence and conscientiousness, with participants changing both their competence‐communicating behaviours and self‐evaluations in response to the cultural primes of spoken language and ethnicity of an interviewer. These results converge to show that self‐perceptions and self‐presentations change to fit the social contexts shaped by language and culture.

Previous work has shown that older adults attend to and implicitly remember more distracting information than young adults; however, it is unknown whether they show a corresponding decrease in implicit memory for targets in the presence of distracters. Using implicit memory tests, we asked whether older adults show a tradeoff in memory between targets and distracters. Here, young and older adults performed a selective attention task in which they were instructed to attend to target pictures and ignore superimposed distracter words. We measured priming for distracter words using fragment completion and for target pictures using naming time. Older adults showed greater priming for distracting words compared to young adults, but equivalent priming for target pictures. These results suggest that older adults have a broader attentional scope than young adults, encompassing both relevant and irrelevant information. 相似文献
