A fundamental step in learning words is the development of an association between a sound pattern and an element in the environment. Here we explore the nature of this associative ability in 12‐month‐olds, examining whether it is constrained to privilege particular word forms over others. Forty‐eight infants were presented with sets of novel English content‐like word–object pairings (e.g. fep) or novel English function‐like word–object (e.g. iv) pairings until they habituated. Results indicated that infants associated novel content‐like words, but not the novel function‐like words, with novel objects. These results demonstrate that the mechanism with which basic word–object associations are formed is remarkably sophisticated by the onset of productive language. That is, mere associative pairings are not sufficient to form mappings. Rather the system requires well‐formed noun‐like words to co‐occur with objects in order for the linkages to arise. 相似文献

When children draw in clinical contexts, clinicians sometimes rely on children's colour use to make inferences about their emotional reaction to the subject of the drawing. Here, we examined whether children use colour to portray emotion in their drawings. In Experiment 1, children indicated their colour preferences and then coloured in outlines of figures characterized as nasty or nice. Children also drew complex, multi‐coloured pictures about their own happy or sad experiences. In Experiment 2, hospitalized children drew about being worried or scared in hospital and about their positive experiences. In both experiments, we examined the relation between children's colour use and their colour preferences. Three‐ to 10‐year‐old children used more preferred colours to colour in the nice outline. Although they were more likely to use non‐preferred colours to colour in the nasty outline, they tended to used a mix of preferred and non‐preferred colours. When both normal and hospitalized children produced drawings about positive and negative events, there was no relation between children's colour choices and their colour preferences; children primarily used preferred colours. These data suggest that clinicians should exercise extreme caution when interpreting the meaning of colour in children's drawings. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

A randomized controlled trial (RCT) of telephone-delivered cognitive-behavioral therapy (CBT) was compared with usual care for late-life anxiety disorders. Client satisfaction, as assessed by the Client Satisfaction Questionnaire, was high (M = 27.4, range 8-32), and attrition rates were low (8.3%). Preliminary results suggest that participants receiving CBT, compared with usual care, experience declines in general anxiety, worry, anxiety sensitivity, and insomnia. 相似文献

The current study evaluated the degree to which startle reflexes (SRs) in safe conditions versus danger conditions were predictive of the onset of anxiety disorders. Specificity of these effects to anxiety disorders was evaluated in comparison to unipolar depressive disorders and with consideration of level of neuroticism. A startle paradigm was administered at baseline to 132 nondisordered adolescents as part of a longitudinal study examining risk factors for emotional disorders. Participants underwent a repetition of eight safe-danger sequences and were told that delivery of an aversive stimulus leading to a muscle contraction of the arm would occur only in the late part of danger conditions. One aversive stimulus occurred midway in the safe-danger sequences. Participants were assessed for the onset of anxiety and unipolar depressive disorders annually over the next 3 to 4 years. Larger SR magnitude during safe conditions following delivery of the aversive stimulus predicted the subsequent first onset of anxiety disorders. Moreover, prediction of the onset of anxiety disorders remained significant above and beyond the effects of comorbid unipolar depression, neuroticism, and subjective ratings of intensity of the aversive stimulus. In sum, elevated responding to safe conditions following an aversive stimulus appears to be a specific, prospective risk factor for the first onset of anxiety disorders. 相似文献

We examined the role of dehumanization in people's attitudes toward the rehabilitation of sex offenders. In Study 1, the more participants dehumanized sex offenders, the less they supported their rehabilitation and the longer the sentences they recommended. In Study 2, the more participants dehumanized sex offenders, the more likely they were to support their exclusion from society. In Study 3, the more participants dehumanized sex offenders, the more they supported their violent ill treatment. In Study 4, within a sample of correctional staff, good quality contact with sex offenders was related to less dehumanization and more support for rehabilitation. Mediation analyses indicated that the relationship between quality of contact and support for rehabilitation was mediated via dehumanization. 相似文献

We investigated the effect of lexical stress on 16-month-olds' ability to form associations between labels and paths of motion. Disyllabic English nouns tend to have a strong-weak (trochaic) stress pattern, and verbs tend to have a weak-strong (iambic) pattern. We explored whether infants would use word stress information to guide word-action associations during learning. Infants heard two novel words with either verb-like iambic stress or noun-like trochaic stress. Each word was paired with a single novel object performing one of two path actions and was tested using path-switch trials. Only infants in the iambic stress condition learned the association between the novel words and the path actions. To further investigate infants' difficulty in mapping the trochaic labels to the actions, we conducted an additional study in which infants were given an object switch task using the trochaic labels. In this case, infants were able to associate the trochaic labels with the objects, providing further support that infants use lexical stress to guide label-referent associations. This study demonstrates that by 16months, English-learning infants have developed a bias to expect disyllabic action labels to have iambic stress patterns, consistent with native language stress patterns. 相似文献

This study examined mother-child shared book reading behaviors before and after participation in a random-assignment responsive parenting intervention called Play and Learning Strategies (PALS) that occurred during infancy (PALS I), the toddler-preschool (PALS II) period, or both as compared with a developmental assessment (DAS) intervention (DAS I and/or II). The efficacy of PALS was previously demonstrated for improving mother and child behaviors within play contexts, everyday activities, and standardized measures of child language. We hypothesized that PALS effects would generalize to influence maternal and child behaviors during a shared reading task even though this situation was not a specific focus of the intervention and that this would be similar for children who varied in biological risk. Participation in at least PALS II was expected to have a positive effect due to children's increased capacity to engage in book reading at this age. Four groups of randomized mothers and their children (PALS I-II, PALS I-DAS II, DAS I-PALS II, DAS I-II) were observed in shared reading interactions during the toddler-preschool period and coded for (a) mother's affective and cognitive-linguistic supports and (b) child's responses to maternal requests and initiations. Support was found for significant changes in observed maternal and child behaviors, and evidence of mediation was found for the intervention to affect children's behaviors through change in maternal responsiveness behaviors. These results add to other studies supporting the importance of targeting a broad range of responsive behaviors across theoretical frameworks in interventions to facilitate children's development. 相似文献

To read or not to read: a meta-analysis of print exposure from infancy to early adulthood 总被引:2,自引:0,他引:2
This research synthesis examines whether the association between print exposure and components of reading grows stronger across development. We meta-analyzed 99 studies (N = 7,669) that focused on leisure time reading of (a) preschoolers and kindergartners, (b) children attending Grades 1-12, and (c) college and university students. For all measures in the outcome domains of reading comprehension and technical reading and spelling, moderate to strong correlations with print exposure were found. The outcomes support an upward spiral of causality: Children who are more proficient in comprehension and technical reading and spelling skills read more; because of more print exposure, their comprehension and technical reading and spelling skills improved more with each year of education. For example, in preschool and kindergarten print exposure explained 12% of the variance in oral language skills, in primary school 13%, in middle school 19%, in high school 30%, and in college and university 34%. Moderate associations of print exposure with academic achievement indicate that frequent readers are more successful students. Interestingly, poor readers also appear to benefit from independent leisure time reading. We conclude that shared book reading to preconventional readers may be part of a continuum of out-of-school reading experiences that facilitate children's language, reading, and spelling achievement throughout their development. 相似文献

The present study examined the flexibility with which people can adopt different category schemes in the spatial domain. In
a location memory task, participants viewed and estimated the locations of four kinds of objects that were spatially grouped
by object identity. This identity-based arrangement was either congruent or incongruent with the perceptually based, geometric
categories that have been reported in previous research. Four experiments examined the conditions under which these different
category schemes are used to inform estimates of locations. The results showed that use of identity information depended on
the number of objects to be remembered during a trial: When one or two objects were remembered at a time, only geometric categories
affected estimates, but when four objects were to be remembered, both geometric categories and identity groupings affected
estimates. As memory load increases, participants rely on additional sources to inform their estimates of location. 相似文献
