In 3 experiments, we investigate how anxiety influences interpretation of ambiguous facial expressions of emotion. Specifically, we examine whether anxiety modulates the effect of contextual cues on interpretation. Participants saw ambiguous facial expressions. Simultaneously, positive or negative contextual information appeared on the screen. Participants judged whether each expression was positive or negative. We examined the impact of verbal and visual contextual cues on participants' judgements. We used 3 different anxiety induction procedures and measured levels of trait anxiety (Experiment 2). Results showed that high state anxiety resulted in greater use of contextual information in the interpretation of the facial expressions. Trait anxiety was associated with mood-congruent effects on interpretation, but not greater use of contextual information. 相似文献

The present study examined whether reactive and reflective autonomy moderated individuals' responses to expert influence. Participants were given the opportunity to win money at a racetrack betting task for which they were provided with objective information about horses' previous performances along with specific expert recommendations. The experts were made to look either credible or noncredible by manipulating information on the success rate of their previous predictions. The results showed that the two forms of autonomy led to exactly opposite behaviors in response to the advice of credible experts. Reflective autonomy was significantly positively associated with following the recommendations of credible experts whereas reactive autonomy was significantly negatively associated with following the recommendations. The results also showed that it was particularly after losing their first race that reactive autonomy was related to rejecting the advice of experts. These findings indicate that reactive and reflective forms of autonomy may yield opposite patterns of behavior in certain situations. 相似文献

Laboratory studies of analogical reasoning have shown that subjects are mostly influenced by superficial similarity in the retrieval of source analogs. However, real-world investigations have demonstrated that people generate analogies using deep structural features. We conducted three experiments to determine why laboratory and real-world studies have yielded different results. In the first two experiments, we used a "production paradigm" in which subjects were asked to generate sources for a given target. Results show that the majority of the analogies that were generated displayed low levels of superficial similarity with the target problem. Moreover, most of the analogies were based on complex underlying structures. The third experiment used a "reception paradigm" methodology. The subjects had to retrieve predetermined sources instead of generate their own. In this case, retrieval was largely constrained by surface similarity. We conclude that people can use structural relations when given an appropriate task and that this ability has been underestimated in previous research on analogy. 相似文献

Individuals and organizations frequently tout creative ideas as a desirable goal, and yet, creative ideas are frequently rejected. Creativity researchers have often suggested that creative ideas are rejected because they are perceived as riskier due to their inherent novelty or originality. Although this assumption is prevalent, we are unaware of any empirical research directly examining the relations between perceptions of novelty and risk. We provide an empirical test of this assumption in two studies in which participants rate the novelty, usefulness, and riskiness of ideas. Across both studies, we find consistent support for the idea that usefulness, rather than novelty, has the strongest relation with risk perceptions. We also find some evidence that novelty and usefulness interact to predict perceptions of risk. Additionally, in Study 2, we find that usefulness has the strongest relation with willingness to invest and buy a product. The findings of this study suggest that the bias against creativity may be driven by the perceived usefulness of an idea, rather than its novelty, such that ideas with lower usefulness are perceived to be riskier. 相似文献

This study examined memory functioning in children and adolescents with 22q11.2 Deletion Syndrome (DS; velocardiofacial syndrome). An overall verbal better than nonverbal memory pattern was evident on the Test of Memory and Learning (TOMAL), with children with 22q11.2 DS performing significantly below their siblings and children with low average IQ but similar to children with autism on facial memory. Children with 22q11 DS also performed significantly below their siblings on tests of verbal working memory. Children with autism performed significantly poorer than the siblings of children with 22q11.2 DS only on their recall of stories. Delayed recall was significantly poorer in children with 22q11.2 DS and children with autism, compared to sibling controls. Although there were no significant group differences on tests of multiple trial verbal or visual learning, a relative weakness was noted with multiple trial visual learning in children with 22q11.2 DS and their siblings, suggesting that an alternative or interactive factor other than the deletion may account for the relatively better verbal compared to nonverbal memory abilities. Deficits in facial memory in children with both 22q11.2 DS and autism suggest disruptions in ventral temporal pathways such as between fusiform gyrus and parahippocampal/hippocampal regions whereas deficits in verbal working memory in children with 22q11.2 DS implicates dorsolateral prefrontal regions, both intimating aberrant white matter pathways. 相似文献

The authors investigated (a) whether the specificity of practice hypothesis is mediated by the importance of visual afferent information for the control of manual aiming movements and (b) how movement planning and online correction processes to the movement initial impulse are affected by the withdrawal of visual information in transfer. In acquisition, participants (N = 40) aimed at targets of different sizes in a full-vision or in a target-only condition before being transferred to a target-only condition without knowledge of results. The results supported the hypothesis that learning is specific to the source or sources of afferent information that are more likely to ensure optimal performance. The results also suggested that individuals will not always use visual afferent information more extensively when aiming at a small rather than at a large target. Instead, in a temporally constrained task, the relative efficiency of visually based corrections appears to mediate how exclusively an individual will rely on online visual afferent information for movement control. Finally, the detailed kinematic analysis performed in the present study clearly indicated that online modifications to the movement primary impulse are possible, arguing for a continuous or pseudo-continuous control of relatively slow aiming movements on the basis of visual afferent input. 相似文献

Faces from another race are generally more difficult to recognize than faces from one's own race. However, faces provide multiple cues for recognition and it remains unknown what are the relative contribution of these cues to this “other-race effect”. In the current study, we used three-dimensional laser-scanned head models which allowed us to independently manipulate two prominent cues for face recognition: the facial shape morphology and the facial surface properties (texture and colour). In Experiment 1, Asian and Caucasian participants implicitly learned a set of Asian and Caucasian faces that had both shape and surface cues to facial identity. Their recognition of these encoded faces was then tested in an old/new recognition task. For these face stimuli, we found a robust other-race effect: Both groups were more accurate at recognizing own-race than other-race faces. Having established the other-race effect, in Experiment 2 we provided only shape cues for recognition and in Experiment 3 we provided only surface cues for recognition. Caucasian participants continued to show the other-race effect when only shape information was available, whereas Asian participants showed no effect. When only surface information was available, there was a weak pattern for the other-race effect in Asians. Performance was poor in this latter experiment, so this pattern needs to be interpreted with caution. Overall, these findings suggest that Asian and Caucasian participants rely differently on shape and surface cues to recognize own-race faces, and that they continue to use the same cues for other-race faces, which may be suboptimal for these faces. 相似文献

With the rapid shifts in the education of women in the United States, and the underrepresentation of women in fields of science, technology, engineering, and math (STEM), an issue generating much controversy is whether women may benefit more from single-sex education or coeducation. The present study surveyed 548 U.S. high-school boys and girls from single-sex and coeducational high-schools from the Midwest. Half of the participants completed a mathematics test under stereotype threat (ST) condition and half under no threat condition. Although girls in single-sex schools had higher achievement motive and self-esteem than those in coeducational schools, they were not more likely to pursue STEM careers. Overall, students in single-sex schools outperformed students from coeducational schools on the math test. Girls?? math performance was significantly higher in the ST condition than in the no threat condition. 相似文献

Mental retardation is a group of cognitive disorders with a significant worldwide prevalence rate. This high rate, together with the considerable familial and societal burden resulting from these disorders, makes it an important focus for prevention and intervention. While the diseases associated with mental retardation are diverse, a significant number are linked with disruptions in epigenetic mechanisms, mainly due to loss-of-function mutations in genes that are key components of the epigenetic machinery. Additionally, several disorders classed as imprinting syndromes are associated with mental retardation. This review will discuss the epigenetic abnormalities associated with mental retardation, and will highlight their importance for diagnosis, treatment, and prevention of these disorders. 相似文献
