情感一致性是指情感具身反应(情感感受、表情及情感的相关身体动作等)和情感认知评价(情感观念性内容,积极或消极)在效价层面上的耦合关系。实验以89名大学生为被试,考察了情感一致性对(性别)刻板印象的影响。实验通过音乐启动相应的情感感受(积极或消极)操纵情感具身反应,采用快速组句任务启动相应的情感信念(积极或消极)操纵情感认知评价,89名被试被随机分配到四种实验条件下,最后所有被试参与(性别)刻板印象IAT测验。结果发现:情感不一致条件促进(性别)刻板印象激活;情感一致性没有导致流畅性的变化;情感感受调节了消极阈下情感信念对刻板印象激活的作用。 相似文献

以汉语单字词为材料,使用单一启动与单一探测范式,探查清楚和模糊启动汉字在呈现时间比较短暂时,能否发生负启动.结果显示,不论单一启动汉字是清楚还是模糊,也不论启动刺激的呈现时间长还是短,均未发生负启动效应.提示,启动刺激本身变模糊,即使呈现时间短暂依然能够自动微弱地激活大脑中与该词有关的表征,若不能阻止这种微弱激活的扩散也不能发生单一启动与单一探测范式下的负启动.这个结果在一定程度上扩展了Collins和Loftus(1975)所提出的激活扩散理论,也提示,启动词的激活水平和注意的抑制机制对单一启动与单一探测范式中负启动的发生同样重要. 相似文献

摘要:本研究致力于探讨自上而下的任务因素对自动反应激活过程的影响。研究包含两个实验,采用掩蔽启动范式,选取字母和数字作为刺激,任务因素为与当前任务无关的处于预备状态的任务规则。实验一初步验证了与当前无关的处于预备状态的任务规则可以影响自动反应激活过程;实验二进一步证明了这种影响具有广泛性,即与当前无关的任务规则所设定的所有刺激系列都可以影响当前任务中的反应启动过程。研究总结论为:与当前任务目的无关、且存在自动刺激-反应联结的其他任务规则也能通过对被掩蔽的启动刺激反应的调节来影响对靶刺激的反应,从而影响启动效应的发生。 相似文献

双加工理论认为锻炼行为形成中自动加工(系统1)和熟虑加工(系统2)是两个相互作用但又截然不同的信息处理系统,其中自动评价通过触发系统1的自动加工过程激活运动记忆自发的心理联想,并对运动进行情感评价,从而影响锻炼行为。本研究的目的是检测锻炼相关刺激在不同锻炼人群中引发的自动评价特点。采用评价启动任务范式,实验1和实验2分别给予阈上和阈下锻炼词或非锻炼词作为启动刺激,之后要求被试对积极或者消极目标词进行按键反应。研究结果显示无论阈上还是阈下呈现锻炼启动词,均表现为锻炼组对积极目标词反应速度更快。结果表明:锻炼人群对于锻炼词具有积极自动评价。 相似文献

字词语义的加工是否受其它加工过程或操纵手段的控制一直是自动化研究的热点,以往针对英文字词的研究结果不尽一致。本研究以在该类研究中比英文单词更具优越性的汉字为材料,采用部件搜索任务,通过操纵控制水平的强弱探讨汉字的语义加工是否受控制这一问题。实验一考察汉字的语义是否受浅水平加工和无意识操纵的控制(低控制水平);实验二探讨增强了的控制水平是否能够控制语义的加工。结果在实验一中发现了语义负启动效应;实验二出现了正启动和负启动效应。该结果表明,控制机制并不能阻止汉字语义加工本身的发生,仅能对已经产生激活的语义进行调控,提示汉字的语义加工是不可控的。 相似文献

成就目标启动对风险偏好的调节作用 总被引:1,自引:1,他引:0
新近研究发现,目标可以在无意识的条件下被激活并自动地引导行为以达成目标,但其内部机制尚不清楚。本研究试图考察风险偏好是否受无意识目标调节。实验采用问卷作为启动刺激,分别启动被试追求成功的目标与避免失败的目标,并在收益框架下和损失框架下测量被试的风险偏好。结果发现:在收益框架下,受到追求成功目标启动的被试比受到避免失败目标启动的被试更加偏好风险;而在损失框架下,两组被试间未发现显著差异。上述结果表明自动激活的成就目标可以影响个体的风险偏好,使个体面对风险情境时能做出更合适的行为以达成目标,即对风险偏好的调节是无意识目标自动影响行为的途径之一。 相似文献

The argument that automatic processes are responsible for affective/evaluative priming effects has been primarily based on studies that have manipulated the stimulus onset asynchrony (SOA; i.e., the interval between the onset of the prime and the onset of the target). Moreover, these SOA studies provide an insight in the time course of the activation processes underlying automatic affect/attitude activation. Based on a fine-grained manipulation of the SOA employing either the evaluative decision task (Experiment 1) and the pronunciation task (Experiment 2) we concluded that affective priming, and hence automatic affect activation, is based on fast-acting automatic processes. The results of Experiment 3 provide a valid explanation for an apparent discrepancy between the results of Experiments 1 and 2 and previous findings. Finally, the results of Experiment 3 support the prediction of Jarvis and Petty (1996) that affective priming effects should be stronger for participants who are more chronically engaged in conscious evaluations. 相似文献

Among the most influential models of automatic affective processing is the spreading activation account (Fazio, Sanbonmatsu, Powell, & Kardes, 1986). However, investigations of this model by different research groups using the pronunciation task in an affective priming paradigm yielded contradictory results. Whereas one research group reported congruency effects, another obtained reversed priming effects (contrast effects), and still another found null effects. In Experiment 1, we were able to show an influence of trait anxiety on the direction of the affective priming effect. By using a multiple priming paradigm in Experiment 2, we were able to link the occurrence of reversed priming effects to increased levels of activation of affective representations. We propose that this relation might underlie the influence of trait anxiety on the direction of affective priming effects. Both experiments indicate that automatic evaluation in an affective network is substantially moderated by personality traits and activation level. 相似文献

Behavior may be automatically prompted by cues in our social environment. Previous research has focused on cognitive explanations for such effects. Here we hypothesize that affective processes are susceptible to similar automatic influences. We propose that exposure to groups stereotyped as dangerous or violent may provoke an anxiety response and, thus, a tendency to move away. In the present experiment, we subliminally exposed participants to images of such a group, and found that they displayed greater avoidance in a subsequent interaction. Critically, this effect was explained by their increased sensitivity to threat-related information. These findings demonstrate an affective mechanism responsible for nonconscious priming effects on interpersonal behavior. 相似文献

Recently, using a conditional pronunciation task, De Houwer and Randell (2004) reported evidence of affective priming effects only when pronunciation depended on the semantic category of targets. Although these findings support the notion that spreading of activation is the mechanism underlying affective priming effects, an explanation in terms of postlexical mechanism could not be ruled out. To clarify this point, we conducted two experiments in which nouns for both the to-be-pronounced as well as the not-to-be pronounced targets were used and all stimuli were affectively valenced words. In Experiment 1, the to-be-pronounced targets were object-words, and the not-to-be-pronounced targets were person-words, whereas in Experiment 2, the instructions were reversed. Results of experiment 1 showed affective priming effects only when pronunciation of target words was conditional upon their semantic category. Most importantly, affective priming effects were observed for both object-words (Experiment 1) and person-words (Experiment 2). These results are compatible with a spreading activation account, but not with a postlexical mechanism account of affective priming effects in the pronunciation task. 相似文献

Recent studies have shown that robust affective priming effects can be obtained when participants are required to categorize the targets on the basis of their valence, but not when participants are asked to categorize the targets on the basis of nonaffective features. On the basis of this pattern of results, it has been argued that affective priming is due to processes that operate at a response selection stage rather than to processes that operate at an encoding stage. We demonstrate (a) that affective priming of nonaffective semantic categorization responses can be obtained when participants assign attention to the affective stimulus dimension, and (b) that affective priming in the standard evaluative categorization task is strongly reduced when participants assign attention to nonaffective stimulus features. On the basis of these findings, we argue (a) that processes operating at an encoding stage do contribute to the affective priming effect, and (b) that automatic affective stimulus processing is reduced when participants selectively attend to nonaffective stimulus features. 相似文献

Sexual stimuli may elicit positive and negative emotions that can impact sexual thoughts, responses, and behavior. To date, most research on affect and sexuality has focused on conscious processes and affective states. Less is known about how automatic and trait-level affective processes influence our reactions to sexual stimuli. This study used a priming task with backward masking and a trait measure of erotophobia-erotophilia - the tendency to respond to sex on a negative-to-positive continuum - to improve our understanding of the role of automatic and affective processes in response to sexual stimuli. Erotophilic individuals demonstrated automatic associations between sexual primes and positively-valenced targets, whereas erotophobic individuals classified negatively-valenced targets faster regardless of whether primes were sexual or neutral. The findings suggest that the valence of sexual stimuli can be processed automatically and is associated with trait-level affective responses to sex. Implications for research on risky sexual behavior and sexual dysfunction are discussed. 相似文献

An immense body of research demonstrates that emotional facial expressions can be processed unconsciously. However, it has been assumed that such processing takes place solely on a global valence-based level, allowing individuals to disentangle positive from negative emotions but not the specific emotion. In three studies, we investigated the specificity of emotion processing under conditions of limited awareness using a modified variant of an affective priming task. Faces with happy, angry, sad, fearful, and neutral expressions were presented as masked primes for 33 ms (Study 1) or 14 ms (Studies 2 and 3) followed by emotional target faces (Studies 1 and 2) or emotional adjectives (Study 3). Participants' task was to categorise the target emotion. In all three studies, discrimination of targets was significantly affected by the emotional primes beyond a simple positive versus negative distinction. Results indicate that specific aspects of emotions might be automatically disentangled in addition to valence, even under conditions of subjective unawareness. 相似文献
