This study investigated the interaction between children's parasympathetic functioning and maternal sensitive parenting behaviors during infancy and toddlerhood in the prediction of children's executive functions (EF) at the age of 5 years. Participants included 137 children and their mothers who were followed from the age of 3 months to 5 years. Children's cardiac activity was recorded at rest at multiple times from ages 3 to 36 months, and estimates of respiratory sinus arrhythmia (RSA; a measure of parasympathetic functioning) were calculated. Sensitive parenting was assessed during a mother–child play task at ages 6, 12, 24, and 36 months, and 5 years. Children completed age appropriate EF tasks at the age of 5 years. The link between sensitive parenting during toddlerhood (ages 24 and 36 months) and children's later EF was moderated by children's RSA such that this positive link was evident only among children who had low levels of baseline RSA, and not among those who had high levels of baseline RSA. These findings were obtained while controlling for concurrent sensitive parenting and maternal and child verbal abilities. Results from this study provide evidence for the significant role of biopsychosocial processes in early childhood in the development of EF.  相似文献

This experiment recreates several features of the selection of candidates for junior professional positions. The situation of central interest involves an assessor (either male or female) and a pair consisting of a male and a female applicant with either equivalent or slightly different academic records. We also investigate effects from quality of record (either excellent or poor) and type of decision (namely, choice between applicants, and ratings of competence and suitability). Our hypotheses consider both gender as social status and as social identity, and predict different outcomes depending on decision type. In line with those predictions, findings show that, at both levels of performance, the question about competence elicited effects only from the two applicants’ relative academic standing, while the choice and suitability measures show effects from that standing as well as from sex category of applicant and of assessor. Results and their interpretation are presented and discussed in detail.  相似文献

This study investigates the characteristics of individuals with DSM-IV pathological gambling (PG) who experienced childhood maltreatment and rates of maltreatment occurring in their first-degree relatives (FDRs). 94 subjects with DSM-IV PG, 91 controls, and 312 FDRs were assessed for childhood maltreatment as part of a family study of PG. Maltreatment was evaluated using the Revised Childhood Experiences Questionnaire. The Family Assessment Device was used to evaluate the functionality of the PG subject’s (or control’s) family of origin. Data were analyzed using logistic regression by the method of generalized estimating equations. Rates of maltreatment were significantly higher in subjects with PG than controls (61 vs. 25 %, P < 0.001). Subjects with PG who experienced maltreatment were more likely to be female, had more severe PG symptoms, had co-occurring mood and anxiety disorders, and reported greater early family life dysfunction than those with PG who did not experience maltreatment. Rates of maltreatment were higher in FDRs of PG subjects than controls (41 vs. 24 %, P = .002). Rates in FDRs of individuals with PG who experienced maltreatment themselves were still higher that in FDRs of those with PG who did not experience maltreatment (50 vs. 28 %, P = .009). The former were also more likely to have anxiety disorders, substance use disorders, and suicide attempts. The results suggest that childhood maltreatment in persons with PG is common and intergenerational. Rates of maltreatment in FDRs of PG subjects are high, particularly among those who experienced abuse. The implications of the findings are discussed.  相似文献

This paper explores the salience of the “crisis” in boys’ education as it is articulated in Australian print media. We will consider the ways in which this crisis is expressed through a gendered language which simultaneously represents boys as “forgotten” by teaching practices thought to be prioritising girls’ learning, and as an equity (disadvantaged) grouping who require specialised teaching methods different from those currently offered within the Australian school system. Further, we will examine the extent to which feminist-inspired reforms in education are either implicitly or explicitly referenced as an explanation for boys’ apparently poor education attainment, and relatedly consider the work of “experts” supporting claims of a pro-feminine bias that adversely affects boys’ learning outcomes, particularly those experts offering neurological or psychological/cognitive findings which assert a biological basis for gender difference. In this context, we argue that rather than advancing gender equity in schools, popular public discourse, as presented in Australian print media, reinforces and perpetuates notions of gender difference and masculine entitlement.  相似文献

In response to the recent economic crisis in Korea and its negative effects on families, the current study examined the interrelationships among economic pressure, emotional distress, marital conflict, and marital satisfaction for 236 Korean couples. The family stress model ( Conger & Elder, 1994 ; Conger, Rueter, & Conger, 2000 ; Conger, Rueter, & Elder, 1999 ) was tested using structural equation modeling. The results generally supported the theoretical model, showing that economic pressure negatively affects marital satisfaction via emotional distress and marital conflict. The results also implied cultural differences in the process of family stress. Korean husbands' emotional distress did not affect marital conflict or marital satisfaction, suggesting that Korean husbands may differ from their wives in their reaction to emotional distress from economic pressure.  相似文献

This study tested two models of family economic problems and adolescent psychological adjustment. Using adolescents’ survey data and information regarding school lunch program enrollment, the associations among family SES, perceived economic strain, family conflict, and coping responses were examined in a sample of 364 adolescents from rural New England. Two theoretical models were tested using structural equation modeling — one tested coping as a mediator of the stress – psychopathology relation and the other tested coping as a moderator. Results revealed that family economic hardship was related to aggression and anxiety/depression primarily through two proximal stressors: perceived economic strain and conflict among family members. Family conflict partially mediated the relation between economic strain and adolescent adjustment, and coping further mediated the relation between family conflict and adjustment. These analyses identified two types of coping that were associated with fewer anxiety/depression and aggression problems in the face of these stressors — primary and secondary control coping. Although primary and secondary control coping were associated with fewer adjustment problems, youth who were experiencing higher amounts of stress tended to use less of these potentially helpful coping strategies and used more of the potentially detrimental disengagement coping. The models did not differ according to the age or gender of the adolescents, nor whether they lived with two parents or fewer. No support was found for coping as a moderator of stress. Implications of these findings and suggestions for future research involving coping with economic stressors are reviewed.  相似文献

This article investigates the effects of stock market wealth on consumer spending. Traditional macroeconometric models estimate that a dollar's increase in stock wealth boosts consumption by three to seven cents. With the substantial 1990s rise in stock prices, the nature and magnitude of this "wealth effect" have been much debated. After describing the issues and previous research, I present new evidence from a well‐known consumer survey. The results are broadly consistent with life‐cycle saving and a modest wealth effect: most stockholders reported no appreciable effect of stock prices on their saving or spending, but many mentioned "retirement saving" in explaining their behavior.  相似文献

This paper combines optimal spatial sampling designs with geostatistical analysis of functional data. We propose a methodology and design criteria to find the set of spatial locations that minimizes the variance of the spatial functional prediction at unsampled sites for three functional predictors: ordinary kriging, simple kriging and simple cokriging. The last one is a modification of an existing predictor that uses ordinary cokriging based on the basis coefficients. Instead, we propose to use a simple cokriging predictor with the scores resulting from a representation of the functional data with the empirical functional principal components, allowing to remove restrictions and complexity of the covariance models and constraints on the estimation procedure. The methodology is applied to a network of air quality in Bogotá city, Colombia.  相似文献

This paper presents a qualitative participatory study of Canadian young people who identified themselves as visible minorities and who have experienced discrimination based on their skin colour or ethnicity. Eighteen participants aged 15–24 (12 girls and 6 boys), representing four ethnic minority groups, participated in focus groups and in-depth interviews and shared their responses to racial discrimination against them. Analysis of the data from the four discussion groups reveals that racism occurs in everyday situations and places, a lot of times manifesting itself as subtle forms of discrimination. Our findings also suggest that most of the participants tend to employ non-confrontational approaches when dealing with racial violence against them, and provide us with the rationale behind their intentions. Further, youth are not uniformly impacted by racialized events, and therefore the coping strategies they use vary based on individual and contextual factors. Three common strategies for healing can be derived from the participants’ narratives: expressive-emotional, spiritual-forgiving and communicative-relational. We discuss our findings in the light of theoretical frameworks of resilience and coping approaches and argue that young people’s subjective appraisals of racialized events as well as contextual factors need to be addressed in any discussion on coping and resilience within minority youth populations.  相似文献
