The high frequency of the fragile X premutation in the general population and its emerging neurocognitive implications highlight the need to investigate the effects of the premutation on lifespan cognitive development. Until recently, cognitive function in fragile X premutation carriers (fXPCs) was presumed to be unaffected by the mutation. Here we show that young adult female fXPCs show subtle, yet significant, age- and FMR1 gene mutation-modulated cognitive impairments as tested by a quantitative magnitude comparison task. Our results begin to define the neurocognitive endophenotype associated with the premutation in adults, who are at risk for developing a neurodegenerative disorder associated with the fragile X premutation. Results from the present study may potentially be applied toward the design of early interventions wherein we might be able to target premutation carriers most at risk for degeneration for preventive treatment. 相似文献

Incorporating input from others can enhance decision quality, yet often people do not effectively utilize advice. We propose that greater power increases the propensity to discount advice, and that a key mechanism explaining this effect is elevated confidence in one’s judgment. We investigate the relationships across four studies: a field survey where working professionals rated their own power and confidence and were rated by coworkers on their level of advice taking; an advice taking task where power and confidence were self-reported; and two advice taking experiments where power was manipulated. Results consistently showed a negative relationship between power and advice taking, and evidence of mediation through confidence. The fourth study also revealed that higher power participants were less accurate in their final judgments. Power can thus exacerbate the tendency for people to overweight their own initial judgment, such that the most powerful decision makers can also be the least accurate. 相似文献

Children acquiring languages with noun classes (grammatical gender) have ample statistical information available that characterizes the distribution of nouns into these classes, but their use of this information to classify novel nouns differs from the predictions made by an optimal Bayesian classifier. We use rational analysis to investigate the hypothesis that children are classifying nouns optimally with respect to a distribution that does not match the surface distribution of statistical features in their input. We propose three ways in which children's apparent statistical insensitivity might arise, and find that all three provide ways to account for the difference between children's behavior and the optimal classifier. A fourth model combines two of these proposals and finds that children's insensitivity is best modeled as a bias to ignore certain features during classification, rather than an inability to encode those features during learning. These results provide insight into children's developing knowledge of noun classes and highlight the complex ways in which statistical information from the input interacts with children's learning processes. 相似文献

This study examined the effects of reading mode (oral and silent) and text genre (narrative and expository) on fourth graders’ reading comprehension. While controlling for prior reading ability of 48 participants, we measured comprehension. Using a repeated measured design, data were analyzed using analysis of covariance, paired t-tests, and correlational statistics. Results revealed that silent reading was stronger for narrative passages in retell measures, but there was no difference for comprehension questions. The expository passages revealed no difference between the reading modes. Comprehension of narrative texts was consistently stronger than expository texts in both silent and oral reading. 相似文献

Our goal was to identify factors that shape women's responses to ingroup members who protest gender discrimination. We predicted and found that women who perceived gender discrimination as pervasive regarded a protest response as being more appropriate than a no protest response and expressed greater liking and less anger towards a female lawyer who protested rather than did not protest an unfair promotion decision. Further, beliefs about the appropriateness of the response to discrimination contributed to evaluations of the protesting lawyer. Perceptions that the complaint was an appropriate response to the promotion decision led to more positive evaluations of an ingroup discrimination protester.

The use of safety behaviors has been considered one of the primary maintaining mechanisms of anxiety disorders; however, evidence suggests that they are not always detrimental to treatment success (Milosevic & Radomsky, 2008). This study examined the effects of safety behaviors on behavioral, cognitive, and subjective indicators of fear during exposure for fear of spiders. A two-stage design was used to examine fear reduction and approach distance during an in vivo exposure task for participants (N = 43) assigned to either a safety behavior use (SBU) or no safety behavior use (NSB) condition. Overall, both groups reported significant and comparable reductions in self-reported anxiety and negative beliefs about spiders at posttest and 1-week follow-up. Participants in the SBU group approached the spider more quickly than did participants in the NSB condition; however, participants in the SBU condition showed a small but significant decrease in approach distance at follow-up. These results call for a reconceptualization of the impact of safety behaviors on in vivo exposure. 相似文献

The present study tested the prediction that counterfactual thinking would have a stronger amplificatory effect on guilt than on shame and that the effect would be mediated by self-blame. Ninety sentenced prisoners were instructed to think either counterfactually or factually about the role they played in the events leading to their capture, conviction, and sentencing prior to reporting on their level of self-blame, guilt, and shame. Compared to factual-focused prisoners, counterfactual-focused prisoners reported feeling more blameworthy and guiltier but not more shameful. The effect of thought focus on guilt was fully mediated by blame. The findings support an emotion-specific account of the emotional consequences of counterfactual thinking that implicate attributional judgment as an important mediating process. 相似文献

Two studies examined the effects of competence‐based respect in relation to liking‐based respect from ingroup members. First, a pilot study confirmed the impact of competence feedback from ingroup members on affective and emotional reactions (membership esteem, feelings of pride and shame). The main studies orthogonally manipulated both liking‐ and competence‐based respect from other ingroup members in order to examine whether (high) competence‐based respect compensates for lack of liking, or compromises the subjective position in the group, on affective and emotional reactions to the feedback. Using a scenario methodology Study 1 produced no evidence for compensation, and indicated that liking was primary in this context. Study 2, using experimental groups, provided further evidence that those who were disliked by their fellow group members felt compromised by a favourable evaluation of their competence, while remaining committed to the group. These effects are related to the different properties and implications of competence and liking dimensions in group interaction. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献
