Child executive functions (cognitive flexibility, inhibitory control, working memory) are key to success in school. Cortisol, the primary stress hormone, is known to affect cognition; however, there is limited information about how child cortisol levels, parenting factors and child care context relate to executive functions in young children. The aim of this study was to examine relationships between child cortisol, parenting stress, parent coping, and daycare quality in relation to executive functions in children aged 3–5 years. We hypothesized that (1) poorer executive functioning would be related to higher child cortisol and higher parenting stress, and (2) positive daycare quality and positive parent coping style would buffer the effects of child cortisol and parenting stress on executive functions. A total of 101 children (53 girls, 48 boys, mean age 4.24 years ±0.74) with complete data on all measures were included. Three saliva samples to measure cortisol were collected at the child’s daycare/preschool in one morning. Parents completed the Behavior Rating Inventory of Executive Function – Preschool Version (BRIEF-P), Parenting Stress Index (PSI), and Ways of Coping Questionnaire (WCQ). The Early Childhood Environment Rating Scale – Revised (ECERS-R) was used to measure the quality of daycare. It was found that children with poorer executive functioning had higher levels of salivary cortisol, and their parents reported higher parenting stress. However, parent coping style and quality of daycare did not modulate these relationships. Identifying ways to promote child executive functioning is an important direction for improving school readiness. 相似文献

Externalizing behaviors are a common component of the clinical presentation of autism spectrum disorders. Although traditionally used with typically-developing children, parent–child interaction therapy (PCIT) is one behaviorally-based parent training program that has demonstrated success in increasing child compliance, reducing problem behavior, and improving parent–child communication. The study examined the efficacy of PCIT as a treatment for children with autism spectrum disorders by employing a single subject, non-concurrent multiple baseline design across three subjects. Primary findings revealed increases in child compliance, reductions in child disruptive behavior, and improved parenting skills across participants. In addition, each caregiver reported high levels of satisfaction with the intervention. Results suggested that PCIT may be a treatment option for children on the autism spectrum with co-occurring behavioral difficulties. Although the non-concurrent nature of the multiple baseline design is a limitation, this study replicates and extends previous research investigating the efficacy of PCIT with children with autism and their parents. 相似文献

Self-directed behaviors (SDBs) are a commonly used behavioral indicator of arousal in nonhuman primates. Experimental manipulations, designed to increase arousal and uncertainty, have been used to elicit SDB production in primates. Beyond measuring rates of SDB production, researchers have also recorded their lateralized production by primates, thought to reflect laterality of hemispheric brain control and response to emotion. Although a handful of such studies exist, all have been conducted with chimpanzees. Expanding on this line of inquiry, we tested both chimpanzees (N = 3) and gorillas (N = 3) in a serial learning task presented on a touchscreen interface that incorporated both EASY (two-item list) and HARD (four-item list) versions of the task. Although SDB production by the apes did not differ across the two levels of task complexity, both species produced higher rates of SDB when they made an error, regardless of task difficulty. Furthermore, the apes made more SDB with the left hand—directed to the right side of their body (contralateral SDB) and left side of their body (ipsilateral SDB)—when they made an incorrect response. There was no difference in the rate of SDB produced with the right hand across correct compared to incorrect trials. The apes’ responses reflect previous reports that show humans are quicker at selecting negative emotional stimuli when using their left, compared to their right, hand (the reverse is true for positive stimuli). However, previous work has shown that chimpanzees are more likely to produce (contralateral) SDB with their right hand when aroused and so we discuss our results in relation to these findings and consider how they relate to the ‘right hemisphere’ and ‘valence’ models of emotional processing in apes. 相似文献

Callous-unemotional (CU) traits are one meaningful risk factor which helps to explain heterogeneity in the emergence of externalizing behavior problems. While the extant literature demonstrates links between early CU traits and later externalizing problems, there is a dearth of research examining for whom early CU traits confer risk. Data from a longitudinal study (n?= 108) were used to examine the extent to which parasympathetic functioning moderated links between CU traits in toddlerhood (m age ?=?24.99 months) and externalizing behavior problems at preschool-age (m age ?=?51 months). Neither CU traits nor parasympathetic functioning at age 2 directly predicted later externalizing behaviors. However, results show that high levels of CU traits predict elevated externalizing behavior problems, but only for toddlers exhibiting either high baseline respiratory sinus arrhythmia (RSA) or little to no RSA suppression in response to a fear stimulus. 相似文献

Regardless of preexisting trauma history, offenders regularly experience traumatic events while incarcerated. Current therapeutic approaches focus on coping skills and behavioral responses. The authors recommend integrating the use of trauma‐informed care to address the deeper emotional responses tied to trauma. 相似文献

This study examines the three-dimensional organizational commitment (OC) concept (Meyer & Allen, 1997) in Nepal. Standardized questionnaires were administered to a heterogeneous sample of 103 employees of four different Nepalese organizations (bank, food corporation, telecommunication, and an airline). Exploratory factor and confirmatory factor analyses replicate the dimensionality of OC, i.e., the three facets of commitment (affective, normative, and continuance commitment) could be found also in a developing country with a cultural background very different from the places where the commitment concept was originally formulated. Antecedents and consequences of organizational commitment were investigated by multiple regression analyses. Continuance and normative commitment were both explained by job characteristics, i.e., by the perception of the job as interesting, affective commitment could not be explained with the set of variables used in this study. However, it is affective commitment which particularly accounts for variance in search intentions as well as in turnover intentions. 相似文献

Battered and nonbattered women were administered the Hand Test to determine which psychological test variables could distinguish between these groups. Compared to the nonbattered group, the battered group produced substantially more fear responses. We also found significant positive relationships between the amount of fear responses produced and frequency of abuse, number of previous visits to a battered women's shelter, and medical treatment sought following an abusive incident. We discuss these results in the context of previous findings and their implications for the personality of battered women. We speculate that lowered environmental interest might be a personality factor that prolonged the abuse and that fear is a basic reaction to anticipated bodily harm. 相似文献
