摘 要:目的 探讨高特质愤怒个体是否对负性情绪面孔有注意偏向。方法 采用点探测任务,比较高低特质愤怒个体(高特质愤怒组23人,低特质愤怒组23人)对不同性质情绪面孔同异侧探测符号反应时的差异。结果 重复测量方差分析发现存在面孔性质边缘主效应(F=2.462,p=.073)及组别与面孔性质的交互效应,探测位置主效应(F=5.089,p=.029)及组别与探测位置的交互效应,组别、面孔性质与探测位置的交互效应。进一步分析发现,高特质愤怒组对愤怒面孔同侧探测刺激反应时显著快于异侧反应时[(386.12±50.09)ms VS.(403.33±59.39)ms,F=17.050,p=.000],快乐面孔同侧探测刺激反应时显著慢于异侧反应时[(396.88±53.87)ms VS.(38.78±41.06)ms,F=18.200,p=.000)],低特质愤怒组被试不同性质面孔同异侧反应时无显著差异。结论 高特质愤怒个体对与愤怒相关刺激存在注意偏向。 相似文献

采用工作记忆算式-词对广度任务,通过87名大学生探索依恋回避倾向性与注意的关系。研究发现:依恋回避与三类词的工作记忆成绩呈负相关;工作记忆广度类型、词类型主效应显著;工作记忆广度类型与词类型交互作用显著。结果表明:回避性依恋者具有回避性注意偏向;回避性注意偏向既有刺激普遍性,又有刺激特定性,依恋性刺激比中性刺激更容易在信息加工早期被防御性地排除;回避性注意偏向具有调节情绪的功能性价值。为去激活策略情绪调节观提供了跨文化研究证据。 相似文献

Sex differences in adults’ observations and ratings of children’s aggression was studied in a sample of preschool children (N = 89, mean age = 44.00 months, SD = 8.48). When examining the direct observations made by trained observers, male observers, relative to female observers, more frequently recorded aggressive bouts, especially of boys. On rating scales assessing aggression, trained male raters also gave higher aggressive ratings than female raters. Lastly, we compared the ratings of trained female raters and female teachers on the same scale and found no differences. Results are discussed in terms male raters’ and observers’ prior experiences in activating their experiential schemata where males’ greater experience in aggression, relative to that of females, leads them to perceive greater levels of aggression. 相似文献

Ideological orientation shapes the perception of the social world and conservatism is associated to an increased weighting of negative over positive information. In the present work we explored how this ideology-based difference is also related to basic cognitive processes involved in attitude formation. In particular, we hypothesized that conservatives, as compared to liberals, would show stronger illusory correlation effects when negative information is relatively infrequent. In Study 1 we employed the typical illusory correlation paradigm (Hamilton & Gifford, 1976) and results confirmed the hypothesis: conservatives developed more negative impressions toward the minority group and showed consistent memory biases. In Study 2, positive information represented the infrequent dimension and in this case no ideology-based difference was observed. Overall, findings indicate that when exposed to numerically different novel groups and negative behaviors are infrequent, illusory correlation effects are accentuated among individuals embracing conservative rather than liberal views of the world. This result may help to understand why conservatives tend to form more negative attitudes toward social minorities. 相似文献

吸烟者对香烟相关线索的注意偏向近年来颇受研究界青睐,现有研究大都集中在吸烟者注意偏向的理论解释、研究范式、发生状况以及与吸烟成瘾的关系等方面。其中,在理论解释上形成了诱因敏感、自动行动图式、诱因习惯和目前关注等理论;在研究范式上主要有成瘾stroop任务、点探测任务和线索调控的惊跳测试;在发生状况上涉及发生的被试特征、发生的意识状态、发生的注意阶段、发生的生化基础;在与吸烟成瘾的关系上包括与主观渴求和与觅烟行为的关系。鉴于目前研究所限,未来研究需纳入线索-靶子等研究范式,以深入探讨吸烟者注意偏向的发生阶段及其与吸烟成瘾的关系,进而发现吸烟者注意偏向的特异性之所在。 相似文献

设计了两个实验任务,探讨了颜色、大小和形状对68名8~10岁儿童归纳推理的影响。结果发现,在相似性任务中,当测试图片分别与两组前提图片在大小和形状(颜色)上一致时,儿童认为测试图形与大小一致图形具有相同属性;当测试图片分别与前提图片在形状和颜色上一致时,儿童倾向于选择形状一致图形具有的属性。在变化性任务中,当两组前提图片分别在大小和形状上变化,而测试图形与前提组图形不同时,儿童认为测试图形与大小变化图形具有相同属性;当两组前提图片分别在颜色和大小(形状)上变化时,儿童的选择没有显著差异;这一结果与同时变化每组前提图片的两个特征差异不显著,表明单独变化颜色、大小和形状来构成推理任务是比较合理的。 相似文献

Although anti-terrorism policy should be based on a normative treatment of risk that incorporates likelihoods of attack, policy makers’ anti-terror decisions may be influenced by the blame they expect from failing to prevent attacks. We show that people’s anti-terror budget priorities before a perceived attack and blame judgments after a perceived attack are associated with the attack’s severity and how upsetting it is but largely independent of its likelihood. We also show that anti-terror budget priorities are influenced by directly highlighting the likelihood of the attack, but because of outcome biases, highlighting the attack’s prior likelihood has no influence on judgments of blame, severity, or emotion after an attack is perceived to have occurred. Thus, because of accountability effects, we propose policy makers face a dilemma: prevent terrorism using normative methods that incorporate the likelihood of attack or prevent blame by preventing terrorist attacks the public find most blameworthy. 相似文献

Implicit motives are one form of motivation that regulates cognitive and emotional processing. In this study, we investigated the impact of implicit power motive (nPower) on the processing of anger faces. Event-related potentials were recorded while high- and low-nPower individuals performed a face version of an emotion Stroop task comprised of anger and neutral faces. It was found that nPower does not modify early perceptual and attentional components (P2 and N2), but a later component is affected. Indeed, power-motivated participants showed enhanced P3/LPPs (Late positive potentials) amplitude compared to low-nPower subjects, in response to anger stimuli. These findings demonstrate that anger faces have greater salience for high-nPower individuals and are subject to a more salient, conscious processing. 相似文献

Standardized tests are used widely in comparative studies of clinical populations, either as dependent or control variables. Yet, one cannot always be sure that the test items measure the same constructs in the groups under study. In the present work, 460 participants with intellectual disability of undifferentiated etiology and 488 typical children were tested using Raven's Colored Progressive Matrices (RCPM). Data were analyzed using binomial logistic regression modeling designed to detect differential item functioning (DIF). Results showed that 12 items out of 36 function differentially between the two groups, but only 2 items exhibit at least moderate DIF. Thus, a very large majority of the items have identical discriminative power and difficulty levels across the two groups. It is concluded that RCPM can be used with confidence in studies comparing participants with and without intellectual disability. In addition, it is suggested that methods for investigating internal bias of tests used in cross-cultural, cross-linguistic or cross-gender comparisons should also be regularly employed in studies of clinical populations, particularly in the field of developmental disability, to show the absence of systematic measurement error (i.e. DIF) affecting item responses. 相似文献

The tendency to interpret ambiguous everyday situations in a relatively negative manner (negative interpretation bias) is central to cognitive models of depression. Limited tools are available to measure this bias, either experimentally or in the clinic. This study aimed to develop a pragmatic interpretation bias measure using an ambiguous scenarios test relevant to depressed mood (the AST-D).1 In Study 1, after a pilot phase (N = 53), the AST-D was presented via a web-based survey (N = 208). Participants imagined and rated each AST-D ambiguous scenario. As predicted, higher dysphoric mood was associated with lower pleasantness ratings (more negative bias), independent of mental imagery measures. In Study 2, self-report ratings were compared with objective ratings of participants’ imagined outcomes of the ambiguous scenarios (N = 41). Data were collected in the experimental context of a functional Magnetic Resonance Imaging scanner. Consistent with subjective bias scores, independent judges rated more sentences as negatively valenced for the high versus low dysphoric group. Overall, results suggest the potential utility of the AST-D in assessing interpretation bias associated with depressed mood. 相似文献
