Although parents and children are thought to influence one another's affect and behavior, few studies have examined the direction of effects from children to parents, particularly with respect to parental psychopathology. We tested the hypothesis that children's affective characteristics are associated with the course of mothers' depressive symptoms. Children's affect expression was observed during a series of mother-child interaction tasks, and children's resting frontal electroencephalogram (EEG) asymmetry was assessed in a psychophysiology laboratory. Mothers' depressive symptoms were assessed at two time points, approximately one year apart, at the mother-child interaction visits. Depressive symptoms increased over time for mothers with a history of childhood-onset depression whose children exhibited right frontal EEG asymmetry. Depressive symptoms were associated with high child negative affect at both time points for mothers whose children exhibited right frontal EEG asymmetry. Cross-lagged models with a subset of participants provided some evidence of both parent-to-child and child-to-parent directions of effects. Findings suggest that akin to other interpersonal stressors, children's affective characteristics may contribute to maternal depressive symptoms. 相似文献

There is abundant evidence from behavioral and neurophysiological experiments for the distinction of natural versus artifactual categories and a gender-specific difference: women’s performances in cognitive tasks increase when natural categories are used, whereas men’s performances increase with artifactual categories. Here, we used the semantic priming paradigm to study retrieval processes by presenting category labels as primes and exemplars as targets. Overall, in two experiments we found larger priming effects for natural than for artifactual categories. In addition, females showed positive priming effects for natural but negative effects for artifactual categories, whereas males showed positive priming effects for both categories. This pattern matches with that from other tasks and can be interpreted as evidence that the findings from these other tasks are, at least partially, indeed due to different representations or processing modes for males and females and not (exclusively) due to—for example—different familiarity with a category. In a further experiment, we showed that the found pattern for females can be manipulated by focusing on perceptual vs. functional features. The results can be interpreted as first evidence that there are (eventually in addition to different “crystallized” semantic structures) specific default processing modes that differ for males and females. 相似文献

采用信号检测论技术,以人格词单记忆为实验任务,探讨社会认知过程中样例激活效应与内-外群体效应对记忆过程的干扰作用.实验结果表明,(1)样例激活与群体范畴的交互效应对社会信息加工过程存在显著干扰作用.(2)与外群体相比,内群体的信息加工更不易受到干扰;与积极样例特质相比,消极他相关样例特质的信息加工更不易受到干扰.(3)在加工内群体成员信息而激活的是反面样例时,被试的判断标准最严. 相似文献

简单结构刺激非规则特征突显条件下的样例效应 总被引:2,自引:1,他引:1
用变化了的Allen和Brooks的实验范式,采用2(学习轮次:5轮、10轮)×2(项目类型:旧项目、新项目)×2(项目匹配性质:正向匹配、反向匹配)混合实验设计,研究对4个特征刺激分类时非规则特征突显条件下的样例效应。结果发现,无论是错误率还是反应时都取得了明显的样例效应,但是学习时间的影响不明显。 相似文献

This study explores the utility of a pain IAT for the assessment of dysfunctional cognitive beliefs in chronic pain patients before and after a cognitive behaviour therapy. A patient group suffering from chronic pain (N=25) treated with a 4-week cognitive behavioural psychotherapy is compared with an untreated healthy control group (N=27) at two points in time. In addition, both groups completed a self-esteem questionnaire (Rosenberg-scale) and a self-esteem IAT. In the clinical group a questionnaire assessing self-reported pain cognitions was administered. The pain IAT was able to differentiate between chronic pain patients and healthy controls before the treatment. Most important, pain-related implicit associations could be shown to change over the course of treatment in the clinical group of chronic pain patients. Results provide first evidence for an application of the IAT in chronic pain research. 相似文献

Testing boundary conditions for the conjunction fallacy: effects of response mode, conceptual focus, and problem type 总被引:1,自引:0,他引:1
Two experiments used within-subject designs to examine how conjunction errors depend on the use of (1) choice versus estimation tasks, (2) probability versus frequency language, and (3) conjunctions of two likely events versus conjunctions of likely and unlikely events. All problems included a three-option format verified to minimize misinterpretation of the base event. In both experiments, conjunction errors were reduced when likely events were conjoined. Conjunction errors were also reduced for estimations compared with choices, with this reduction greater for likely conjuncts, an interaction effect. Shifting conceptual focus from probabilities to frequencies did not affect conjunction error rates. Analyses of numerical estimates for a subset of the problems provided support for the use of three general models by participants for generating estimates. Strikingly, the order in which the two tasks were carried out did not affect the pattern of results, supporting the idea that the mode of responding strongly determines the mode of thinking about conjunctions and hence the occurrence of the conjunction fallacy. These findings were evaluated in terms of implications for rationality of human judgment and reasoning. 相似文献

Does Islamic appearance increase aggressive tendencies, and what role does affect play in such responses? In a computer game, participants made rapid decisions to shoot at armed people, some of whom wore Islamic head dress. We predicted and found a significant bias for participants to shoot more at Muslim targets. We also predicted and found that positive mood selectively increased aggressive tendencies towards Muslims, consistent with affect-cognition theories that predict a more top-down, stereotypical processing style in positive mood. In contrast, induced anger increased the propensity to shoot at all targets. The relevance of these results for our understanding of real-life negative reactions towards Muslims is discussed, and the influence of affective states on rapid aggressive responses is considered. 相似文献

采用自定步速阅读的方法, 从体验认知的角度探索了汉语简单否定句的动态理解过程。以具有对立谓词的汉语陈述性的肯定句和否定句为实验句, 以与否定句的两种状态相对应的图片为实验图片, 并构成句子-图片匹配/不匹配两种匹配状态。研究结果表明, 实验1在以250 ms为间隔时间的条件下, 肯定句和否定句的理解有显著的匹配效应; 实验2以750 ms为间隔时间, 则未表现出匹配效应, 而实验3以1500 ms为间隔时间, 肯定句和否定句的理解又表现出显著的匹配效应。实验结果证明, 具有对立谓词的简单的汉语否定句理解的心理模拟过程, 并不像两步模拟假设所设想的那样遵循着先模拟被否定状态再模拟实际状态的顺序, 而是在理解的初期就完成了对事件的实际状态的模拟。 相似文献
