Although childhood generalized anxiety disorder is generally understudied, worry, the cardinal feature of GAD, appears to be relatively common in youth. Despite its prevalence, there are few conceptual models of the development of clinical worry in children. The current review provides a framework for integrating the developmental psychopathology perspective, models of worry in adults, and data available on worry in children. General risk factors for the development of worry are considered, as well as potential pathways including genetics, temperament, cognitive, emotional and parenting influences, as well as the influence of cognitive development. Based on this review, it appears unlikely that main effects models will be able to explain the development of GAD or clinical worry in children and that a broad, complex model incorporating a number of factors and their interactions will best describe etiological and maintaining factors. With this perspective in mind, a number of suggestions for future work are offered.  相似文献

In Chinese orthography, a dominant character structure exists in which a semantic radical appears on the left and a phonetic radical on the right (SP characters); a minority opposite arrangement also exists (PS characters). As the number of phonetic radical types is much greater than semantic radical types, in SP characters the information is skewed to the right, whereas in PS characters it is skewed to the left. Through training a computational model for SP and PS character recognition that takes into account of the locations in which the characters appear in the visual field during learning, but does not assume any fundamental hemispheric processing difference, we show that visual field differences can emerge as a consequence of the fundamental structural differences in information between SP and PS characters, as opposed to the fundamental processing differences between the two hemispheres. This modeling result is also consistent with behavioral naming performance. This work provides strong evidence that perceptual learning, i.e., the information structure of word stimuli to which the readers have long been exposed, is one of the factors that accounts for hemispheric asymmetry effects in visual word recognition.  相似文献

This study investigated the "knew it all along" explanation of the hypercorrection effect. The hypercorrection effect refers to the finding that when people are given corrective feedback, errors that are committed with high confidence are easier to correct than low-confidence errors. Experiment 1 showed that people were more likely to claim that they knew it all along when they were given the answers to high-confidence errors as compared with low-confidence errors. Experiments 2 and 3 investigated whether people really did know the correct answers before being told or whether the claim in Experiment 1 was mere hindsight bias. Experiment 2 showed that (a) participants were more likely to choose the correct answer in a 2nd guess multiple-choice test when they had expressed an error with high rather than low confidence and (b) that they were more likely to generate the correct answers to high-confidence as compared with low-confidence errors after being told they were wrong and to try again. Experiment 3 showed that (c) people were more likely to produce the correct answer when given a 2-letter cue to high- rather than low-confidence errors and that (d) when feedback was scaffolded by presenting the target letters 1 by 1, people needed fewer such letter prompts to reach the correct answers when they had committed high- rather than low-confidence errors. These results converge on the conclusion that when people said that they knew it all along, they were right. This knowledge, no doubt, contributes to why they are able to correct those high-confidence errors so easily.  相似文献

Motor experts can accurately predict the future actions of others by observing their movements. This report describes three experiments that investigate such predictions in everyday object manipulations and test whether these predictions facilitate responses to the actions of others. Observing video excerpts showing an actor reaching for a vertically mounted dial, participants in Experiment 1 needed to predict how the actor would rotate it. Their predictions were specific to the direction and extent of the dial rotation and improved proportionate to the length of the video clip shown. Testing whether such predictions facilitate responses, in the subsequent experiments responders had to undo an actor's actions, back-rotating a dial (Exp 2) and a bar (Exp 3). The responders' actions were initiated faster when the actors' movements obeyed the so-called end-state comfort principle than when they did not. Our experiments show that humans exploit the end-state comfort effect to tweak their predictions of the future actions of others. The results moreover suggest that the precision of these predictions is mediated by perceptual learning rather than by motor simulation.  相似文献

This study examined how endorsement of benevolent sexist ideologies predicts perceptions of requesters who use a term of endearment and of the female addressees who comply with their requests. Undergraduate women who previously completed the Benevolent Sexism Scale as part of the Ambivalent Sexism Inventory were randomly assigned to one of four groups. They watched one of four videos in which a female addressee responded to a request that either included or did not include the term of endearment "hon"; the requester was either male or female. Participants then rated both actors' social likeability. Among participants who watched a woman respond to a female requester who addressed her with the term "hon," benevolent sexism scores predicted liking for the female responder and disliking of the female requester. Findings reflect the dissatisfaction of women who are high in benevolent sexism with women who act outside of traditional gender role expectations.  相似文献

The origins of the bilingual advantage in various cognitive tasks are largely unknown. We tested the hypothesis that bilinguals' early capacities to track their native languages separately and learn about the properties of each may be at the origin of such differences. Spanish-Catalan bilingual and Spanish or Catalan monolingual infants watched silent video recordings of French-English bilingual speakers and were tested on their ability to discern when the language changed from French to English or vice versa. The infants' performance was compared with that of previously tested French-English bilingual and English monolingual infants. Although all groups of monolingual infants failed to detect the change between English and French, both groups of bilingual infants succeeded. These findings reveal that bilingual experience can modulate the attentional system even without explicit training or feedback. They provide a basis for explaining the ontogeny of the general cognitive advantages of bilinguals.  相似文献

Empirical data on genetic counseling outcomes in the deaf population are needed to better serve this population. This study was an examination of genetics knowledge before and after culturally and linguistically appropriate pre-test genetic counseling in a diverse deaf adult sample. Individuals ≥18?years old with early-onset sensorineural deafness were offered connexin-26/30 testing and genetic counseling. Participants completed questionnaires containing 10 genetics knowledge items at baseline and following pre-test genetic counseling. The effects of genetic counseling, prior beliefs about etiology, and participant's preferred language on genetics knowledge scores were assessed (n?=?244). Pre-test genetic counseling (p?=?.0007), language (p?相似文献

We examined cultural differences in mothers’ acceptance of and intent to use behavioral parenting techniques for managing disruptive child behavior, and the possible roles of parenting styles and implicit theories in explaining these cultural differences. A community sample of 117 Euro-Canadian and Chinese-immigrant mothers of boys aged 4- to 8-years participated. Chinese-immigrant mothers had more favorable attitudes towards punishment techniques (i.e., overcorrection and spanking) than Euro-Canadian mothers, and mothers’ authoritarian parenting style accounted for this cultural difference. No cultural differences were found in mothers’ attitudes towards reward (i.e., praise and token economy) or withdrawal of positive reinforcement (i.e., response cost and time-out). This study helps to inform efforts to increase the cultural sensitivity of mental health services for the underserved population of Chinese-immigrant families.  相似文献

A new measure of Erikson’s final psychosocial stage, Integrity versus Despair, is presented and validated across two studies. In the first, 97 adults (68 women and 31 men) aged 65 and older responded to this measure: the Self-Examination Interview (SEI). Responses on the SEI were treated both categorically and dimensionally (continuous scores) with respect to four integrity statuses: Integrated, Nonexploring, Pseudointegrated, and Despairing. In Study One, categorical and dimensional Integrity statuses were examined in relation to five convergent measures: the Integrity subscale of the Modified Eriksonian Psychosocial Inventory, Openness to Experience, the Competence subscale of the California Personality Inventory, the Geriatric Depression Scale, and Perceived Health. As hypothesized, Integrated respondents were socially competent and resilient; Nonexploring persons conventional; Pseudointegrated respondents immature; and Despairing persons, demoralized. A subsample of participants took a semi-structured Adult Identity Status Interview. Integrated persons were most often Identity Achieved; Pseudointegrated and Nonexploring persons were most often Foreclosed. Study Two evaluated a new sample of 70 persons (51 women and 19 men) aged 70 and older. It generally confirmed the Integrity statuses developed in Study One, extending them to variables related to complexity and maturity of sociomoral reasoning and thinking style. As expected, the Integrated status was negatively related, and the Nonexploring status positively related, to intolerance for ambiguity. The highest levels of sociomoral reasoning occurred most in the Integrated status group, as did dialectical reasoning. In contrast, the Nonexploring and Despairing statuses had more formistic-mechanistic reasoners. Pseudointegrated persons produced the highest number of invalid protocols. The importance of present findings and implications of these studies for future directions in integrity research are discussed.  相似文献
