This is a study of differences in physical contact and tactile interpersonal behaviours between Hispanic and Anglo mothers and infants living in the United States. Infants were 9 months old and 52 mother–infant dyads, 26 Hispanic and 26 Anglo, were videotaped during free play without toys in a university laboratory playroom. Coders judged the interpersonal distance, physical contact and affectionate touch from the videotapes and mothers responded to a questionnaire about the importance of physical contact and affectionate touch in their relationship with their infant. From questionnaire data we found that Hispanic and Anglo mothers both touch their infants on a daily basis, although Hispanic mothers report touching more frequently, being more affectionate with their infants and having more skin-to-skin contact. From videotaped observations we found that there were no overall differences in mother–infant touch between the two cultures; however, the Hispanic mothers showed more close touch and more close and affectionate touch compared to Anglo mothers, who showed more distal touch. The results are discussed in terms of the role of touch in infant development and cultural differences in the evaluation of close physical contact and touch.  相似文献

From studies over the past 20 years four contrasting hypotheses can be made about the nature of parent–infant communication: (1) mothers and fathers display similar skills to their infants and do not exert a differential influence on their development; (2) fathers are less sympathetic to their infants' level of development and therefore inadvertently stretch the child's development more than mothers; (3) both parents differentially socialize their sons' and daughters' early communicative skills; (4) any apparent differences between parents reflect their expectations about being observed. To examine these hypotheses together, this experiment records the communication of 10 mother–infant and 10 father–infant dyads in two conditions: when an observer was present or absent. The analysis revealed two patterns. Firstly, in keeping with most research on parent–child communication, mothers and fathers both simplified their speech to their infants in similar ways. Secondly, both the structure and function of parental communication showed differences between the two conditions and many of these differences were moderated by interactions between condition and sex of parent or child. The data thus provide more support for the first and fourth hypotheses cited above. It is suggested that analyses of parent–infant interaction should move away from simple assumptions about parental ‘influences’ upon children's development to consider the subtleties of different parental styles in different settings.  相似文献

The aim of the present study was to examine the moral and conventional rules in 40 same-sex and same-age 4- and 5-year-old preschoolers’ dyads during their play interaction. Significant gender differences were found both in the dominant social domain and in the prevailing types of rules within each domain. Boys referred to moral rules more often than girls did. In the category of moral rules, boys were significantly more likely to bring up justice and rights issues than girls were. In the category of conventional rules, girls focused on miscellaneous and general conventions and boys on the destruction of property. Moral rules were applied more frequently in conflict situations. Regardless of gender, the rules of justice were the most likely moral rules to engender conflicts.  相似文献

Preadolescent children who did not know one another interacted in a multiuser domain (MUD), an online site designed to facilitate identity exploration and peer interaction. Each child participated in two separate sessions, one with a same-sex and one with an opposite-sex peer. Children created characters that reflected real-life properties of themselves, such as gender and interests in popular culture. Boys in same-sex pairs interacted with one another through action, rapid changes, and playful exchanges. Girls in same-sex pairs interacted primarily through written dialogue. In mixed pairs, boys wrote more and engaged in less playful exchanges, and girls wrote fewer and increased their actions. The results suggest that boys and girls have their own unique play styles with same-sex peers, but will moderate those patterns during late childhood to communicate with peers of the opposite sex.  相似文献

We hypothesized a mediating role for low maternal responsiveness in certain child developmental deficits found previously to be associated with postnatal depression. Forty depressed inpatients and 48 control (non-depressed) mothers and their infants were followed until 42 months postpartum. Mother–infant interactions were impaired at 6 months postpartum in the depressed group. Subsequent cognitive deficits were found in children's Full Scale IQ on the Wechsler Preschool Primary Scale of Intelligence (Revised) at 42 months of age. Statistical modeling of the mediation hypothesis confirmed that these effects were overwhelmingly explained by lowered maternal responsiveness at 6 months. Similarly, increased temperamental difficulties were apparent in children of depressed mothers but were not correlated with maternal responsiveness. Male infants of depressed mothers were disproportionately vulnerable (compared to females) to impaired cognitive abilities associated with maternal depression. The data concur with previous work and provide empirical support for the theoretical prediction that early disturbances of the mother–infant interaction will mediate some developmental deficits in the children of depressed mothers.  相似文献

This study examined whether the effects on cognitive and language outcomes of a recently developed home‐based educational intervention program, Opstap Opnieuw, for 4–6‐years‐old disadvantaged children could be explained by improved mother–child interaction. The present sample (n=30) was drawn from a larger sample of Turkish–Dutch families (n=181) for which in a previous study significant effects of Opstap Opnieuw were found on children's (first) language and cognitive pre‐math skill, 5 months after the program ended. The present study focused on two facets of interaction quality as possible mediators of these program effects: the mean cognitive distancing level of mothers' communication and instruction behaviour as an indicator of the cognitive and verbal stimulation provided, and the degree of cooperation as an indicator of mothers' social‐emotional support to their children. Both measures were based on systematic observation of mother–child interaction during sorting tasks. Participation in the program appeared to improve mothers' social‐emotional support behaviour substantially, but not their cognitive distancing behaviour. For Turkish (first language) vocabulary, about half of the program effect appeared to be mediated by the improved social‐emotional support. For cognitive pre‐mathematical skills, two‐thirds of the program effect appeared to be mediated by improved social‐emotional support. Mothers' cognitive distancing was moderately‐strongly related to children's vocabulary development, but did not mediate program effects. Some implications of the results are discussed.

In this study, we examined relations between kindergartner's emotional security, task involvement and achievement and teacher's supportive presence in a cognitive training setting, in which the familiarity of the teacher was varied. Participants were 48 kindergarten children (mean age=51.65 months); 16 children were trained by their regular teacher (experimental group 1), 16 by a less familiar teacher (experimental group 2) and 16 received no training (control group). In three training sessions, children worked in pairs on a new categorization and recall task. Trained observers rated children's emotional insecurity and task involvement and teacher's supportive presence. Furthermore, spontaneous recall during the training was assessed. In addition, categorization and spontaneous recall was measured in various test sessions. Children's emotional insecurity during training negatively affected involvement. Involvement on its turn positively influenced spontaneous recall during training. In addition, emotional insecurity had a direct negative effect on spontaneous recall in a test situation. No effect of familiarity or supportive presence of the teacher on emotional security was found. Training conditions did not affect test performances. Findings suggest that children's involvement is important for learning and that experiences of emotional insecurity may negatively affect task involvement, test performance and eventually school achievement. Teachers in general seem capable of providing children with some sense of security. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

The author comments on this case report from a relational and intersubjective perspective. He emphasizes the here-and-now, interactive attunement and the emergence and development of the patient's nascent healthy core, more than the interpretation of defense. A case report of clinical material selected and condensed by someone else necessarily lacks many of the subtle, non-verbal clues and shared treatment memory that the author would rely on for his perspective. Thus he approaches this report as a written narrative of manifest interaction and gives his impressions of how he might have understood the material and responded somewhat differently. He concludes that, although he and the treating analyst would have different conceptions of how the pivotal moment emerged, the outcome might not have been very different. Finally, he challenges the common usage of 'homosexual' to denote a certain dynamic position in a context that has nothing to do with sexual desire.  相似文献

人们在识别自己所熟悉的物体时, 不仅依赖于对输入信息的感知而且还会受到自上而下调节机制的影响。研究者基于功能磁共振成像(fMRI), 利用虚幻探测范式对自上而下字母加工的神经网络进行研究。该研究要求被试从纯噪声(实际没有任何字母)中探测字母。通过对fMRI数据进行心理生理交互效应分析, 发现当被试从纯噪声图片中“看”到字母时, 多个脑区的活动由于受到来自于右侧梭状回的影响而加强。该发现表明自上而下的字母加工网络不但包含负责字母形状和语音加工的脑区, 还涉及一些负责高级认知加工的区域。  相似文献
