Demographic variables, findings from the Metacognitive Awareness Inventory (Schraw & Dennison, 1994), the Learning Strategies Survey (Kardash & Amlund, 1991), and the Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991), as well as accuracy ratings of test performance, were examined in 2 studies. Findings indicated convergence of self-report measures of metacognition, significant correlations between metacognition and academic monitoring, negative correlations between self-reported metacognition and accuracy ratings, and positive correlations between metacognition and strategy use and metacognition and motivation. Limitations of the studies and implications for theory development and future research are discussed.  相似文献

Children's exposure to intimate partner violence (IPV) is increasingly recognized as a type of child maltreatment that has a level of impairment similar to other types of abuse and neglect. Despite advances in the area of IPV, the safety planning strategies recommended as part of the overall response to IPV need to be examined in terms of their implications for children. This article discusses these strategies within the context of child safety, comparing IPV safety planning with approaches aimed at reducing exposure to other types of violence such as child sexual abuse, as well as general child safety strategies. Despite the emphasis on safety planning in information available on responding to IPV, the actual effectiveness of such planning in improving safety and reducing violence is unknown. Safety planning provided to children by a parent experiencing IPV, especially when IPV is ongoing and not recognized by anyone outside the home, may lead to confusing messages for children, particularly if there is an emphasis on secrecy. While awaiting evidence about the effectiveness of specific safety planning strategies for children, we suggest basic principles and general strategies that emphasize universality in terms of education about any type of violence or abuse in the home being unacceptable, as well as the need to focus on safety in general.  相似文献

A hurdle-jump escape response was employed to assess the laboratory rat’s aversion or attraction to different types of conspecific odor. Odorant donor subjects received 112 runway acquisition trials on a continuous reward schedule followed by 32 extinction trials, 112 acquisition trials on a 50% schedule of reward and nonreward followed by 32 extinction trials, or 144 “neutral” trials with no reward in the alley. Different groups of test subjects escaped from odor excreted by odorant subjects on (a) nonrewarded acquisition and extinction trials, (b) rewarded trials during continuous reinforcement, (c) rewarded trials during partial reinforcement, or (d) neutral trials; others escaped from a clean box. The principal findings were: (1) significant aversion to “odor of nonreward” appeared after the donor odorants had received 12 exposures to reward; (2) production of odor of nonreward by odorant subjects changed as a function of training experience with reward; (3) after repeated exposure to odor of nonreward, the escape response habituated; (4) greater or different odor excretion in extinction resulted from subjects trained on a continuous reward schedule than on a partial reward schedule. Relationships of the data to frustration theory were discussed, assuming that inferred differences in production of odor reflect differences in frustration reaction.  相似文献

To investigate the role of early regulatory problems (RP), such as problems in feeding, sleeping, and calming down during later development, the association between parent-reported RP at 3 months (no-RP, n = 110; RP, n = 66) and attention to emotional faces at 8 months was studied. Eight-month-old infants had a strong tendency to look at faces and to specifically fearful faces, and the individual variance in this tendency was assessed with eye tracking using a face-distractor paradigm. The early RPs were related to a lower attention bias to fearful faces compared to happy and neutral faces after controlling for temperamental negative affectivity. This suggests that early RPs are related to the processing of emotional information later during infancy.  相似文献

This longitudinal study evaluated the extent to which maternal responsiveness across early childhood and children's cognitive skills predicted children's 8-year decoding and reading comprehension skills for children who varied in biological risk (term, n = 83; preterm, n = 155). Patterns of maternal responsiveness during infancy (6, 12, and 24 months) and preschool (3 and 4 years) revealed 4 maternal clusters that varied in consistency and level of maternal responsiveness. Although not predictive of decoding skills, the interaction between children's 4-year cognitive ability and maternal responsiveness cluster predicted children's reading comprehension skills at 8 years of age, regardless of risk. Although consistently high levels of maternal responsive parenting across early childhood related to literacy outcomes for all children in the study, responsive parenting had a stronger relation to later reading comprehension skills for children with lower cognitive abilities, particularly when mothers demonstrated high responsiveness in children's infancy.  相似文献

Although the engagement of grandparents in grandchildren’s life has increased, there is a lack of research that explores the values that grandparents desire to transmit to their grandchildren. The aim of this study was to analyze the factor structure, the validity, and the reliability of the Values Aspired for the Future Scale in a sample of grandparents. Three hundred grandparents participated in this study. Confirmatory factor analysis showed a three-factor structure with an excellent overall fit: personal and relationship values, abilities and knowledge values, and materialistic values. Grandparents’ sex did not have a moderating effect on the factor structure. An adequate internal consistency was obtained. Signi?cant associations between values, health-related quality of life, social support, and psychological well-being were found, with the exception of the materialistic values. This scale should be tested in different cultural contexts in order to confirm the results found. The implications of the results are discussed.  相似文献

Summary Career counseling cannot be neatly separated from the counseling that affects the remainder of clients' lives, and mental distress cannot be considered independent of the career which encompasses so much of an individual's world. Life is complex and includes many facets which counselees bring to the counseling relationship. Counselors must be able to deal with the major issues in clients' lives including career issues and issues of mental health. Minimum skill for counselors would include the ability to assist a range of clients and the knowledge to effectively refer others. For too long career counseling and mental health counseling have been viewed as separate entities. This view of career and mental health counseling as separate is inconsistent with the development of counseling as a profession and does not serve potential clients well.Spencer G. Niles, D.Ed. is an Assistant Professor of Counselor Education and Robert H. Pate, Jr., Ph.D. is a Professor of Counselor Education and Chair of the Department of Human Services in the Curry School of Education at the University of Virginia.  相似文献
