If the phonological codes of visually presented words are assembled-rapidly and automatically for use in lexical access, then words that sound alike should induce similar activity within the internal lexicon.Towed is homophonous with TOAD, which is semantically related tofrog, andbeach is homophonous withbeech, which is semantically related totree. Stimuli such as these were used in a priming-of-namingtask, in which words homophonous with associates of the target words preceded the targets at an onset asynchrony of 100 msec. Relative to spelling controls (trod, bench), the low-frequencytowed and the high-frequencybeach speeded up the naming offrog andtree, respectively, to the same degree. This result was discussed in relation to the accumulating evidence for the primacy of phonological constraints in visual lexical access. nt]mis|This research was supported in part by National Institute of Child Health and Human Development Grants HD-08945 and HD-0 1994 to the first author and Haskins Laboratories, respectively. 相似文献

This article reviews the literature on psychosocial correlates of contraceptive practices among sexually active late adolescents (primarily college undergraduates). It seeks to help identify subgroups of adolescents who either do not use or misuse contraceptive means, putting them at risk for unwanted pregnancy, AIDS, and other sexually transmitted diseases. The intent is to promote further research on those variables with the most potential for predicting contraceptive behaviors, which will assist in the development and implementation of effective prevention and intervention programs. 相似文献

Social learning plays an important role in acquiring new foraging skills and food preferences in many bird species but its potential role in learning to avoid aposematic prey has never been studied. We tested the effect of social learning on the acquisition of avoidance of aposematic insect prey (firebug Pyrrhocoris apterus; Heteroptera) in juvenile, hand-reared great tits (Parus major). Behaviour towards aposematic prey was compared between two groups of birds: (1) the observers that were, prior to encounter with firebugs, allowed to watch the experienced conspecific demonstrator repeatedly refuse to attack the prey, and (2) the control birds that lacked this opportunity. Observing an experienced demonstrator was not sufficient for learning complete avoidance, because birds from both groups attacked at least the first firebug they had encountered in avoidance training. However, the opportunity to observe the avoidance behaviour of another bird significantly increased the rate of subsequent individual learning of observers in comparison with control birds. Social learning also decreased mortality of firebugs killed by the birds during the avoidance learning. Socially enhanced learning to avoid aposematic prey might be a mechanism important especially for naive juvenile birds learning from their parents, but it could also enhance learning in adults from their more experienced flock mates. Because social learning of avoidance may also lead to decreased mortality of aposematic prey, its effect should be taken into account in scenarios considering evolution and maintenance of prey warning signals. 相似文献

School bullying has become a topic of public concern and considerable research in various countries around the world in the last two decades. We summarise characteristics such as types and causes of school bullying, based on findings from various studies. We further review a variety of large-scale, school-based intervention programmes, implemented in different countries and school settings, that have been systematically evaluated. These programmes have varied substantially in their effectiveness in reducing levels of bullying at schools. Reasons for these mixed outcomes are discussed, together with suggestions for improving the effectiveness of future interventions. 相似文献

Sound‐symbolism is the nonarbitrary link between the sound and meaning of a word. Japanese‐speaking children performed better in a verb generalization task when they were taught novel sound‐symbolic verbs, created based on existing Japanese sound‐symbolic words, than novel nonsound‐symbolic verbs ( Imai, Kita, Nagumo, & Okada, 2008 ). A question remained as to whether the Japanese children had picked up regularities in the Japanese sound‐symbolic lexicon or were sensitive to universal sound‐symbolism. The present study aimed to provide support for the latter. In a verb generalization task, English‐speaking 3‐year‐olds were taught novel sound‐symbolic verbs, created based on Japanese sound‐symbolism, or novel nonsound‐symbolic verbs. English‐speaking children performed better with the sound‐symbolic verbs, just like Japanese‐speaking children. We concluded that children are sensitive to universal sound‐symbolism and can utilize it in word learning and generalization, regardless of their native language. 相似文献

The hypothesis that memory is stored through a single stage of consolidation that results in a stable and lasting long-term memory has been challenged by the proposition that reactivation of a memory induces reconsolidation of the memory. The reconsolidation hypothesis is supported by evidence that, under some conditions, post-retrieval treatments affecting amygdala and hippocampus functioning impair subsequent retention performance. We now report that repeated retention testing attenuates the performance impairment induced by post-retrieval reversible inactivation of the amygdala and hippocampus of rats induced by tetrodotoxin. These findings challenge the reconsolidation hypothesis and suggest that the post-retrieval retention performance impairment is best explained as due to temporary retrieval failure. 相似文献

ObjectivesTo examine the use of relaxation skills by differentially skilled athletes in relation to the deliberate practice framework.DesignDifferentially skilled athletes completed a survey about their use of relaxation skills.Method150 athletes representing three skill levels (recreational, college, and professional) completed the deliberate relaxation for sport survey, which assessed relaxation on three deliberate practice dimensions (relevancy, concentration, and enjoyment); time spent in different relaxation skills in a recent typical week; and functions of relaxation.ResultsAthletes perceived relaxation as relevant to performance, requiring concentration, and enjoyable, and the relationships between these dimensions were positive. Professional and college athletes perceived relaxation as more relevant to effective competition than recreational athletes. Professional athletes engaged in more relaxation in a typical week than college and recreational athletes. In a typical week, autogenic, eastern, and muscle relaxation types were used least, deep breathing, meditation, and imagery relaxation types moderately, and stretching most. Athletes reported the primary functions of relaxation were to cope with competitive anxiety and promote recovery but relaxation was also reported to be used to cope with “everyday” anxieties associated with being an athlete. More physical (e.g., muscle relaxation) than mental relaxation types were used in relation to coping with competitive anxiety, whereas more mental (e.g., meditation) than physical relaxation types were used in relation to coping with everyday anxiety.ConclusionsThe study provides support for the sport-specific framework of deliberate practice in relation to use of relaxation skills and informs the current understanding of self-regulation by athletes. 相似文献

The primary objective of this study was to translate and validate Situational Inventory of Body-Image Dysphoria-Short form (SIBID-S) in a Spanish population. The scale consists of 20 items to assess the frequency of dysphoric body-image emotions in certain situational contexts, using a five-point rating scale. The questionnaire was administered to 214 women between the ages of 14 and 29 years, from primary and secondary schools and a university. Principal components analysis indicated a one-factor structure for the entire sample and both younger (<18) and older (≥18) participants. Internal consistency was high (0.94), and the test–retest reliability over 1 month ranged between 0.89 and 0.93. The SIBID-S showed good convergent validity in relation to other pertinent measures of body image, eating pathology, and self-esteem. Moreover, the SIBID-S was differentiated low-risk, subclinical eating disturbed, and clinical eating disordered patients. Results support the potential utility of the SIBID-S in the Spanish female population, including a younger group than previously studied, as well as its usefulness in the assessment of body image among females varying in degrees of eating pathology. 相似文献

Psychometric properties of an instrument for assessing cyber-sex addiction. Cyber-sex addiction is a ?new pathology? whose prevalence has grown rapidly in recent years. Therefore, it is important to have validated assessment instruments. The aim of this study was the adaptation and validation of the Internet Sex Screening Test (ISST) for its use in a Spanish population. The instrument was administered to 1239 Spanish college students. The results yielded five components that account for 47.5% of the variance. Internal consistency was .88 and temporal stability was .84. Moreover, the instrument had adequate convergent and discriminant validity and was related to other behaviors such as the use of pornography, internet addiction, number of hours online and sexual frequency. Therefore, this tool is proposed as an appropriate measure to assess cyber-sex addiction. 相似文献

People are often mistaken when estimating and predicting quantities, and sometimes they report values that they know are false: they lie. There exists, however, little research devoted to how such deviations are being perceived. In four vignette studies, participants were asked to rate the accuracy of inaccurate statements about quantities (prices, numbers and amounts). The results indicate that overstatements are generally judged to be more inaccurate than understatements of the same magnitude; self-favorable (optimistic) statements are considered more inaccurate than unfavorable (pessimistic) statements, and false reports (lies) are perceived to be more inaccurate than equally mistaken estimates. Lies about the future did not differ from lies about the past, but own lies were perceived as larger than the same lies attributed to another person. It is suggested that estimates are judged according to how close they come to the true values (close estimates are more correct than estimates that are less close), whereas lies are judged as deviant from truth, with less importance attached to the magnitude of the deviation. 相似文献
