采用整体检测的变化察觉范式,探讨客体的相似性对客体—空间型认知方式个体视觉工作记忆表征的影响。行为结果显示,在不相似客体的视觉工作记忆表征任务中,客体型者在长延时条件的成绩优于空间型者,而在相似客体的视觉工作记忆表征任务中,两者无差异;ERP结果显示,在不相似客体视觉工作记忆表征任务中,与客体型者相比,空间型者在大脑皮层诱发出更大的负SP。以上结果表明,客体型者比空间型者对不相似客体视觉工作记忆加工具有优势,其潜在机制可能在于,客体型者对不相似客体视觉工作记忆表征时的神经活动效能更高。 相似文献

What makes voters prefer a certain type of politician? First, we argue that voters’ trait preferences follow a “desired leadership” principle. We show that citizens want the ideal-type politician to be more emotionally stable, extravert-assertive, more deliberate-conscientious and open, more honest, but also somewhat more disagreeable than the average citizen. Second, we argue that voters prefer a model candidate with similar basic value-related personality traits. Importantly, we show that trait congruence is partly mediated by core ideological preferences and thus ensures democratic representation. The study’s findings have implications for personalization of politics and democratic representation, because personality traits can be vital cues for voters deciding whether candidates will act in their interest and represent them well. 相似文献

Object similarity can improve visual working memory (VWM) performance in the change-detection task, but impair the recognition performance when it occurs at retrieval of VWM in the recognition task. The effect of direction similarity is an issue that has not been well resolved. Furthermore, electrophysiological evidence in support of the mechanisms that underlie the effects of similarity is still scarce. In the current study, we conducted three behavioural experiments to examine the effects of direction similarity on memory performance with regard to both the encoding and retrieval phases of VWM and one event-related potential (ERP) experiment to explore the neural signatures of direction similarity in VWM. Our behavioural studies indicated that direction similarity improved performance when it occurred at the encoding phase but impaired performance when it occurred at the retrieval phase. Moreover, the ERP experiment showed that the amplitude of the contralateral delay activity (CDA) increased with the increasing set size for similar but not dissimilar directions. In addition, the CDA amplitude for similar directions was lower than that for dissimilar directions at set size 2. Taken together, these findings suggest that direction similarity at encoding has a positive effect on VWM performance and at retrieval has a negative effect. Given that VWM capacity depends on information load and the number of objects, the positive effect of similarity may be attributed to reduced information load of memory objects. 相似文献

IntroductionThe magnitude estimation method is widely applied in diverse areas of psychology. However, Weiss (1972) found that this method may produce judgments that inaccurately represent subjective magnitudes: constructing the stimuli according to a factorial design allowed the bias caused by magnitude estimation to be exposed as a spurious divergence of factorial curves.ObjectiveThe present study experimentally compared magnitude estimation with graphic rating and ratio estimation. The comparison of magnitude estimation with graphic rating retested Weiss's finding. The comparison of magnitude estimation with ratio estimation explored the hypothesis that magnitude estimation may cause a divergence of factorial curves due to the requirement of magnitude estimation to multiply and divide numbers—both ratio estimation and magnitude estimation required participants to judge ratios, but only magnitude estimation required mental multiplication and division.MethodUsing a 3 × 4 factorial experimental design, an achromatic disk was presented concentrically with a larger achromatic square. The brightness of the disk varied with the luminance of the disk and, due to simultaneous contrast, with the luminance of the square. Three different groups of participants judged the brightness of the disk: one group by graphic rating, another by ratio estimation, and the third by magnitude estimation.ResultsIn accord with Weiss's results, graphic rating yielded roughly parallel factorial curves whereas magnitude estimation yielded diverging factorial curves. Ratio estimation also yielded roughly parallel factorial curves, supporting the hypothesis that the magnitude estimation task itself may cause divergence of factorial curves due to the requirement of this method to mentally multiply and divide numbers.ConclusionCaution should be taken in using magnitude estimation, especially in factorial experiments, because this method is likely to cause the researcher to make incorrect inferences about the functional relations between the variables involved in mental information integration. Ratio estimation yields a pattern of factorial curves essentially equivalent to that obtained by graphic rating. 相似文献

This study evaluated the efficacy of (a) remote video-based behavioral skills training (BST) with added speech outlines on teaching public speaking behaviors and (b) remote video-based awareness training (AT) on speech-disfluency rates. A multiple-baseline design across speech behaviors was used to evaluate the training. Remote video-based BST and AT were effective at teaching public speaking behaviors and reducing speech disfluencies, respectively, for both participants. In addition, performance generalized to increased audience size. Although expert ratings of perceived public speaking effectiveness improved following BST, the ratings did not improve and some worsened following AT. Both participants reported satisfaction with video-based BST and AT. One participant reported greater comfort, confidence, overall ability, and less anxiety as a public speaker following BST. Both participants reported greater improvements in those categories following AT. Our results suggest that public speaking behaviors can be taught using remote video-based BST and speech disfluencies can be reduced using remote video-based AT. 相似文献

How are accuracy and assumed similarity associated in first impressions of personality? In a large-scale video perception study, accuracy and assumed similarity were strongly negatively associated across traits, consistent with past research (e.g., Beer & Watson, 2008). However, across perceivers and perceiver-target dyads, the ability to perceive others accurately was independent of the tendency to assume similarity with others. Thus, viewing others in general or specific others as overly similar to the self does not imply viewing them inaccurately. In sum, accuracy and assumed similarity are inversely related when examined across traits but are independent across perceivers and dyads. 相似文献

In social dilemmas, negotiations, and other forms of strategic interaction, mind-reading—intuiting another party’s preferences and intentions—has an important impact on an actor’s own behavior. In this paper, we present a model of how perceivers shift between social projection (using one’s own mental states to intuit a counterpart’s mental states) and stereotyping (using general assumptions about a group to intuit a counterpart’s mental states). Study 1 extends prior work on perceptual dilemmas in arms races, examining Americans’ perceptions of Chinese attitudes toward military escalation. Study 2 adapts a prisoner’s dilemma, pairing participants with outgroup targets. Study 3 employs an ultimatum game, asking male and female participants to make judgments about opposite sex partners. Study 4 manipulates perceived similarity as well as counterpart stereotype in a principal–agent context. Across the studies, we find evidence for our central prediction: higher levels of perceived similarity are associated with increased projection and reduced stereotyping. 相似文献

ABSTRACT Knowledge of cross-informant rating concordance is critical for the assessment of child and adolescent problems in clinical and research settings. We explored parent-youth rating concordance for hair pulling variables, functional impairment, and anxiety symptoms in a sample of child and adolescent hair pullers (n = 133) satisfying conservative diagnostic criteria for trichotillomania (TTM). Whole group analyses reveal significant parent-youth agreement on all study variables. Split group analyses, however, reveal superior parent-youth concordance for the adolescent (15–17 years old) versus younger (10–12 years old) hair pullers for awareness of hair pulling and anxiety scale scores. These results highlight the need for both parent and youth ratings when assessing younger children with TTM. 相似文献
