This research examined attitudes about early academic experiences as well as parental warmth in mothers and fathers of preschool children. Additionally, the relationship of parental altitudes and parental warmth to child academic skills and self-perceptions of competence was investigated. In a sample of 48 middle class preschoolers, fathers had significantly higher expectations in three skill domains (Academic, Athletic, and Artistic), but they did not differ from mothers in attitude regarding Social and Compliance domains. No significant differences emerged between mothers and fathers in their levels of warmth. Parental warmth was not significantly correlated with parental attitudes about early academics, and neither academic attitudes nor warmth predicted child achievement on an Academic Skills Inventory. However, high correlations were found between maternal and paternal warmth and children's self-perceptions on the Harter and Pike Pictorial Scale of Perceived Competence and Social Acceptance, highlighting the strong relationship between parental warmth and child self-efficacy. 相似文献

Research Findings: Across 63 Hong Kong families, both Filipina domestic helpers and mothers separately rated their own caregiving style (warmth and control) and kindergarten children's social competence. Results indicated that Filipina helpers rated themselves as higher in warmth than mothers did. In addition, self-rated warmth of both caregivers, and Filipina domestic helpers' self-perceived control were correlated with children's social competence. With ratings of warmth and control from both Filipina helpers and mothers included in separate regression equations, mothers' warmth was a strong unique correlate of all measures of children's social competence. However, Filipinas' warmth was uniquely associated with children's responsibility only, whereas their control was uniquely associated with children's assertion and responsibility. Practice or Policy: Results extend previous research on the importance of nonparental caregivers for children's social development in a new cultural context. 相似文献

Twelve experienced counselors engaged in an intensive 40-hour training program over a two-week period. It was hypothesized that they would make rapid gains in accurate empathy and non-possessive warmth and that counselors initially highest on these dimensions would show the greatest increase during training. There was a substantial and significant increase in accurate empathy, but counselors initially high (N = 6) and counselors initially low (N = 6) made approximately equal gains on empathy. No overall gains were made on nonpossessive warmth, and there was evidence suggesting that some decrease may have occurred, particularly within those counselors initially providing high levels of warmth. The pre-training empathy and warmth levels of these counselors were compared with those in other studies conducted in training programs not providing specific training in empathy and warmth. The comparison data were consistent with the hypothesis that gains on these dimensions occur after the initial graduate training program. 相似文献

Warmth as a Developmental Construct: An Evolutionary Analysis 总被引：5，自引：1，他引：5
Kevin MacDonald 《Child development》1992,63(4):753-773
This paper provides an evolutionary account of the human affectional system as indexed by the construct of warmth. It is argued that although warmth and security of attachment are often closely intertwined in actual relationships, warmth must be distinguished from security of attachment. Warmth is conceptualized as a reward system which evolved to facilitate cohesive family relationships and paternal investment in children. Individual differences in this system underlie the dimension of warmth in parent-child research as well as a similar dimension revealed in factor-analytic studies of personality traits. Warmth plays an important motivational role in children by facilitating compliance and the acceptance of adult values, and is viewed as one of several discrete evolved systems underlying personality development. Although securely attached children typically have affectionate relationships with caregivers in many societies, it is hypothesized that warmth is complexly related to attachment classification. Consistent with a discrete systems perspective, research is reviewed indicating that relationships based on warmth and affection are often highly compartmentalized and can coexist with relationships based on exploitation and aggression. 相似文献

BackgroundAlcohol use among young adults is highly prevalent. Individuals exposed to childhood maltreatment are particularly vulnerable to alcohol use and alcohol-related problems. Few studies have examined family protective factors, such as parental warmth, that may mitigate the effects of childhood maltreatment on alcohol-related problems.ObjectiveThe current study seeks to examine the extent to which parental warmth reduces the effect of childhood exposure to maltreatment on alcohol-related problems in young adulthood.Participants and settingParticipants were young adults (N = 337; mean age = 21.7), who were recruited from an urban community and completed in-person interviews assessing childhood maltreatment, parental warmth, and alcohol-related problems.MethodsMultiple hierarchical linear regression models were used to examine whether maternal and paternal warmth reduced the impact of childhood exposure to maltreatment on alcohol-related problems in young adulthood. Common risk factors for alcohol-related problems, including psychological symptoms and peer and parental alcohol use, were also entered into the models.ResultsWe found a significant moderating effect of paternal warmth on the associations between childhood emotional abuse and alcohol-related problems (β= -0.29, p < .05). Specifically, the association between emotional abuse and alcohol-related problems was weaker among individuals with higher levels of paternal warmth. Moderating effects of maternal warmth on the maltreatment-problematic alcohol use relation were not supported.ConclusionThe results of this research suggest that parental warmth may not only relate to fewer alcohol-related problems among offspring, but may also modify the associations between childhood emotional abuse and alcohol-related problems during young adulthood. 相似文献
