This study examined the effects of eight 40-minute interaction coaching sessions on the mother-infant interaction patterns of mother-preterm infant dyads. Thirty-five preterm infants and their mothers were matched for sex and then were assigned randomly to a treatment and a no-treatment control group. Behavior counts and ratings of maternal and infant interactive behavior (Interaction Rating Scale; Field, 1980) were obtained from naturalistic home observations, precoaching, postcoaching, and at a 2-month follow-up. It was hypothesized that coaching, which was intended to facilitate more sensitive responding by mothers, would positively influence mother-infant interaction and mothers' knowledge of infant development. The only marginally significant difference between the groups that emerged over time was in knowledge of infant development, in which the treatment group surpassed the control group.  相似文献

Relationships among science, public policy, and the media have long been a topic of controversy. A discussion of this controversy serves to place views on the Rind et al. affair in a broader context and set the stage for constructing more effective working relationships between scientists and both policy and media experts. To advance these relationships, the author offers several recommendations that emphasize ongoing institutional activities and encourage collaboration with other professional organizations.  相似文献

The authors examined the roles of self-esteem and perceived social support in moderating the relationship between dual social expectations (instrumentality and expressivity) and well-being. Participants were 166 female and 87 male students in an urban community in the midwestern United States. After the authors controlled for the main effects of instrumental and expressive expectations, social support, as predicted, moderated the relationship between dual expectations and well-being: With higher levels of social support, higher levels of dual expectations were associated with higher levels of well-being; with lower levels of social support, higher levels of dual expectations were associated with lower levels of well-being. Contrary to predictions, however, self-esteem did not moderate the relation between dual expectations and well-being. The discussion focuses on the importance of social resources in enhancing the potential benefits of dual expectations in interpersonal contexts.  相似文献

The aim of this investigation was to study the relationships between physical activity, motor ability, and school readiness in 6-yr.-old children. In total, 294 healthy children from Tartu were studied (161 boys and 133 girls). The physical activity of children was reported by parents and teachers using the questionnaire of Harro. The motor ability of children was evaluated using various tests from the Eurofit test battery as well as the 3-min. endurance shuttle run test. The Controlled Drawing Observation rest was used as a predictor of school readiness and development of mental abilities. Indoor physical activities predicted 19-25% of total variance in motor scores for these preschool children. Motor ability tests, which demand children's total attention and concentration, appear related to the chosen measures of school readiness.  相似文献

A prior experimental evaluation of a community-based advocacy program for women with abusive partners demonstrated positive change in the lives of women even 2 years postintervention (C. M. Sullivan & D. I. Bybee, 1999). The current study explored the complex mediational process through which this change occurred, using longitudinal structural equation modeling and formal tests of mediation. As hypothesized, the advocacy intervention first resulted in women successfully obtaining desired community resources and increasing their social support, which enhanced their overall quality of life. This improvement in well-being appeared to serve as a protective factor from subsequent abuse, as women who received the intervention were significantly less likely to be abused at 2-year follow-up compared with women in the control condition. Increased quality of life completely mediated the impact of the advocacy intervention on later reabuse. Discussion places advocacy for women in the context of other efforts that are needed to build an effective community response to preventing intimate violence against women.  相似文献

We investigated the joint mediating effects of injuries and stress on the relationship between abuse and women's health. A community sample of 397 women, half of whom had been assaulted by an intimate partner within the prior 6 months, was interviewed about their experience of intimate partner violence, injuries, stress, income, depression, and physical health problems. Structural equation modeling techniques confirmed the complex model of hypothesized indirect effects of abuse on women's physical health problems through injuries, stress, and depression. Stress accounted for 80% of the indirect effect of abuse on women's physical health. Its direct effect on physical health was somewhat larger than its indirect effect through depression, but both processes played a key role in determining the effect of abuse on women's physical health problems. Furthermore, abuse was a stronger predictor of women's stress than was poverty. Implication and future research are discussed.  相似文献

Two experiments test whether isolated visible speech movements can be used for face matching. Visible speech information was isolated with a point-light methodology. Participants were asked to match articulating point-light faces to a fully illuminated articulating face in an XAB task. The first experiment tested single-frame static face stimuli as a control. The results revealed that the participants were significantly better at matching the dynamic face stimuli than the static ones. Experiment 2 tested whether the observed dynamic advantage was based on the movement itself or on the fact that the dynamic stimuli consisted of many more static and ordered frames. For this purpose, frame rate was reduced, and the frames were shown in a random order, a correct order with incorrect relative timing, or a correct order with correct relative timing. The results revealed better matching performance with the correctly ordered and timed frame stimuli, suggesting that matches were based on the actual movement itself. These findings suggest that speaker-specific visible articulatory style can provide information for face matching.  相似文献

We explored the ability of humans to identify individual cats by smell. Twenty-five cat owners were required to indicate which of two odours (one belonging to their own cat and one belonging to an unfamiliar cat) smelt the strongest, most pleasant, and which belonged to their own cat. Only thirteen (52%) of the participants were able to recognise the odour of their own cat.  相似文献

Use of cosmetic surgeries has increased steadily over the last decade, and continues to rise in young and old alike. The purpose of present research was to investigate the relationship of personality to use of cosmetic procedures of various kinds. It was expected that adult attachment style, in particular attachment anxiety, would be positively related to use of cosmetic procedures. Attachment anxiety involves excessive approval seeking and concern over achieving and maintaining the love of significant others (such as romantic relationship partners). Such concerns could, in turn, lead to use of a variety of strategies for maintaining positive regard, including cosmetic surgeries to enhance physical appearance. Results supported this hypothesis, particularly among women. Neuroticism was also related to some procedures, though the relationships were generally weaker than those for attachment anxiety, and largely disappeared in regression analyses that controlled for the separate influence of the two variables.  相似文献

Accessibility of characters in two-character sentences (e.g., The butler helped Calvin at the wedding reception) was investigated with a probe recognition task. Probes were either the first character (e.g., butler) or the second character (e.g., Calvin) in a sentence and were designated by proper names or common nouns crossed with name or noun nonprobes. Results show that (1) probes in first position are more accessible than those in second position, but not when noun probes are paired with name nonprobes, (2) characters designated by names are generally more accessible than those designated by nouns, and (3) the first name in a sentence is more available than other characters, regardless of position. Thus, accessibility of characters in a sentence seems dependent on discourse function, with named characters seen as main characters, rather than on nondiscourse-related factors, such as temporal distinctiveness.  相似文献
