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

Sloutsky and Fisher (2012) attempt to reframe the results presented in Noles and Gelman (2012) as a pure replication of their original work validating the similarity, induction, naming, and categorization (SINC) model. However, their critique fails to engage with the central findings reported in Noles and Gelman, and their reanalysis fails to examine the key comparison of theoretical interest. In addition to responding to the points raised in Sloutsky and Fisher's (2012) critique, we elaborate on the pragmatic factors and methodological flaws present in Sloutsky and Fisher (2004) that biased children's similarity judgments. Our careful replication of that study suggests that, rather than measuring the influence of labels on judgments of perceptual similarity, the original design measured sensitivity to the pragmatics of task demands. Together, the results reported in Noles and Gelman and the methodological problems highlighted here represent a serious challenge to the validity of the SINC model specifically and the words-as-features view more generally.

Gender Dynamics in Mexican American Families: Connecting Mothers’, Fathers’, and Youths’ Experiences
Study goals were to examine the conditions under which congruent and incongruent patterns of parents’ division of household labor and gender role attitudes emerged, and the implications of these patterns for youth gender development. Questionnaire and phone diary data were collected from mothers, fathers, and youths from 236 Mexican American families living in the southwestern US. Preliminary cluster analysis identified three patterns: Traditional divisions of labor and traditional attitudes, egalitarian divisions of labor and egalitarian attitudes, and an incongruent pattern, with a traditional division of labor but egalitarian attitudes. MANOVAs, and follow-up, mixed- and between-group ANOVAs, revealed that these groups of families differed in parents’ time constraints, socioeconomic resources, and cultural orientations. Mothers in the congruent egalitarian group worked more hours and earned higher incomes as compared to mothers in the congruent traditional and incongruent groups, and the emergence of the incongruent group was grounded in within-family, interparental differences in work hours and incomes. Parents’ patterns of gendered practices and beliefs were linked to their youths’ housework participation, time with mothers versus fathers, and gender role attitudes. Youths in the congruent traditional group reported more traditional gender role attitudes than did youths in the congruent egalitarian and incongruent groups, and gender atypical housework participation and time with parents were only observed in the congruent egalitarian group. Findings demonstrate the utility of a within-family design to understand complex gendered phenomena, and highlight the multidimensional nature of gender and the importance of contextualizing the study of ethnic minorities. 相似文献

Preschoolers who explore objects haptically often fail to recognize those objects in subsequent visual tests. This suggests that children may represent qualitatively different information in vision and haptics and/or that children’s haptic perception may be poor. In this study, 72 children (2½-5 years of age) and 20 adults explored unfamiliar objects either haptically or visually and then chose a visual match from among three test objects, each matching the exemplar on one perceptual dimension. All age groups chose shape-based matches after visual exploration. Both 5-year-olds and adults also chose shape-based matches after haptic exploration, but younger children did not match consistently in this condition. Certain hand movements performed by children during haptic exploration reliably predicted shape-based matches but occurred at very low frequencies. Thus, younger children’s difficulties with haptic-to-visual information transfer appeared to stem from their failure to use their hands to obtain reliable haptic information about objects. 相似文献

The number of HIV-positive Latinas of child-bearing age living on the US–Mexico border is a growing concern. Little is known
about how religious beliefs influence the reproductive health decisions of these women in light of disease demands and cultural
and religious norms that support high fertility rates and childbearing. Such decisions may be further complicated by the stigma
of HIV/AIDS and structural issues related to immigration status and trans-border lives. This paper analyzes extant literature
and supports the need for further research so that policy makers and heath and social service providers can develop meaningful
and comprehensive reproductive-health related interventions. 相似文献

The role of sensory awareness in movement control is receiving increasing interest in sports and clinical literature as a feed-forward and feedback mechanism. The aim of the study was to assess the feasibility and effect of training in sensory awareness on dexterity in healthy adults. 29 healthy students were randomly allocated to a single-group, sensory awareness lesson with the dominant hand, the same lesson with the nondominant hand, or to a sham control group. Dexterity measures included the Purdue Pegboard Test, a grip-lift manipulandum, and perceived changes using a questionnaire. The sensory awareness lesson with the dominant hand produced a statistically significant improvement in mean dexterity compared to the control group, but not between the other two pairs of groups. The sensory awareness training paradigm is feasible and a single session improved dexterity in healthy adults. 相似文献

Evidence suggests that parental marital discord contributes to the development of internalizing and externalizing symptoms
in children and adolescents. Few studies, however, have examined the association between parental marital discord and youth’s
response to treatment. The present study examined the impact of interparental discord on treatment response in a randomized
control trial of adolescents with major depression enrolled in the Treatment for Adolescents with Depression Study (TADS).
Participants were 260 adolescents from two-parent households randomly assigned to one of four treatment groups: fluoxetine
(FLX), cognitive behavior therapy (CBT), their combination (COMB), or placebo (PBO). Logistic regressions revealed that parental
marital discord interacted with youth gender and co-morbid oppositionality symptoms to predict group differences in treatment
response. 相似文献

When target-defining features are specified in advance, attentional target selection in visual search is controlled by preparatory top-down task sets. We used ERP measures to study voluntary target selection in the absence of such feature-specific task sets, and to compare it to selection that is guided by advance knowledge about target features. Visual search arrays contained two different color singleton digits, and participants had to select one of these as target and report its parity. Target color was either known in advance (fixed color task) or had to be selected anew on each trial (free color-choice task). ERP correlates of spatially selective attentional target selection (N2pc) and working memory processing (SPCN) demonstrated rapid target selection and efficient exclusion of color singleton distractors from focal attention and working memory in the fixed color task. In the free color-choice task, spatially selective processing also emerged rapidly, but selection efficiency was reduced, with nontarget singleton digits capturing attention and gaining access to working memory. Results demonstrate the benefits of top-down task sets: Feature-specific advance preparation accelerates target selection, rapidly resolves attentional competition, and prevents irrelevant events from attracting attention and entering working memory. 相似文献

We use data collected from employees in five transition economies to study whether locus of control and preference for challenge versus affiliation are positively related to worker performance. We find that earnings are positively related to the internal locus of control and preference for challenge among participants of the Armenian and Serbian surveys. In the Russian sample, earnings tend to be higher among workers with a more internal locus of control. Earnings are not systematically related to personality in Kazakhstan and Kyrgyzstan. For most countries, self-reported performance tends to be significantly higher among workers with preference for challenge. Generally, the size of the personality effect on performance is at least as great as the effect of experience or education. Although more research needs to be done before final conclusions about the causes of cross-country differences can be made, we argue that variation in personality effects across countries may be influenced by level of economic development, degree of market-orientation, and cultural diversity. 相似文献
