Gender-typed behaviors—both gender-conforming and nonconforming—were investigated longitudinally among children in 106 adoptive U.S. families with lesbian, gay, and heterosexual parents at two times (Wave 1, preschool-age; Wave 2, school-age) over 5 years. At Wave 1 (W1), parents reported on children’s gender-typed behavior using the Pre-School Activities Inventory (PSAI; Golombok and Rust 1993), and children’s gender-typed toy play was evaluated using observational methods. At Wave 2 (W2), children reported on their own gender-typed behavior using the Children’s Occupations, Activities, and Traits Personal Measure (COAT-PM; Liben and Bigler 2002). Observations of children’s gender-conforming toy play and parents’ reports of children’s gender nonconformity (PSAI) in early childhood (W1) were associated with children’s self-reports of gender nonconformity (COAT-PM) in middle childhood (W2); toy play was most strongly predictive of gender nonconformity 5 years later. Children’s gender-typed behavior also varied by age and gender at both time points, but no significant differences were found as a function of parental sexual orientation across time. Informative to ongoing debates about same-sex parenting, our findings indicate that among children reared by lesbian, gay, and heterosexual parents, gender-typing appears to be similar, and predominantly gender-conforming, across early to middle childhood.  相似文献

Pinker and colleagues propose two mechanisms - a rule system and a lexical memory - to form past tenses and other inflections. They predict that children's acquisition of the regular inflection is sudden; that the regular inflection applies uniformly regardless of phonological, semantic or other factors; and that the rule system is separably vulnerable to disruption. A connectionist account makes the opposite predictions. Pinker has taken existing evidence as support for his theory, but the review of the evidence presented here contradicts this assessment. Instead, it supports all three connectionist predictions: gradual acquisition of the past tense inflection; graded sensitivity to phonological and semantic content; and a single, integrated mechanism for regular and irregular forms, dependent jointly on phonology and semantics.  相似文献

Look, no hands!     
Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities are necessary for tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.  相似文献

This study examined whether satisfaction from leisure activities moderates the relationship between caregiving demands (i.e., hours per day spent caring for a spouse with dementia) and resting levels of the catecholamines norepinephrine (NE) and epinephrine (EPI). Spousal caregivers (n?=?107; mean age?=?73.95?±?8.12 years) were assessed in home for plasma levels of NE and EPI, amount of care provided, and leisure satisfaction. Regression was used to determine whether leisure satisfaction moderated the relationship between hours providing care per day and catecholamine levels. A significant interaction was found between hours caregiving and leisure satisfaction for NE, but not for EPI. Post?hoc regressions were conducted for both NE and EPI. At low leisure satisfaction, time spent caring for a spouse was positively associated with plasma NE (β?=?0.41; p?=?0.005) and EPI (β?=?0.44; p?=?0.003). In contrast, at high levels of satisfaction, time caregiving was not significantly associated with plasma NE (β?=?-0.08; p?=?0.57) or EPI (β?=?0.23; p?=?0.12). These findings suggest that leisure satisfaction may protect caregivers from increases in catecholamines, which have been implicated in cardiovascular risk. Further support for these findings may impact psychological treatments for distressed caregivers.  相似文献

ABSTRACT

Research on parent–child learning in museums has shown that parents often use conversation to facilitate their children's exploration of exhibits. This observational study investigated whether the patterns of talk found in science and history exhibits are used during parent–child conversations about challenging content such as death and dying and forensics. This research was conducted at a traveling exhibit, Mysterious Bog People, which was on display at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania. Thirty-four families were observed as they interacted with and explored the exhibit. Parent comfort with the content of the exhibit was found to have an impact on the conversations they had with their children and their enjoyment of the exhibit overall. Implications for museum mediation are discussed.  相似文献

Abstract

Sixty male Vietnam combat veterans, 30 hospitalized for post-traumatic stress disorder (PTSD) and 30 with no PTSD or other psychiatric disorder, sorted and labeled their life events into numeric matrices (repertory grids). Through hierarchical-classes analysis of a subject's matrix, we could compare the hierarchical level (elaboration) of the subject's constructs of a negative combat event with the hierarchical levels of other subjects' constructs of negative combat events and with the subject's precombat life event construction. As predicted, the level of construct elaboration was virtually identical for the two groups for precombat non-trauma-related events but was reduced in the PTSD group for the negative combat event. In addition, the Pythagorean distance scores of the PTSD group indicated less conceptual distance between the negative combat event and negative life events after Vietnam compared with the non-PTSD group's scores. Patients with PTSD rated negative life events more extremely (fewer “shades of gray” ratings) than did the non-PTSD group, especially life events that occurred after Vietnam.  相似文献

The heart-lung machine makes open-heart surgery possible by providing extracorporeal blood circulation; however, it creates microemboli in the blood that cause neurological damage. A new filter, designed to remove these emboli, was assessed by preoperative and postoperative Bender Gestalt testing. A lesser degree of the kinds of visual-motor difficulties associated with neurological deficit was produced by patients who received filtered blood. Postoperative impairment was assessed with some precision by using the Pascal-Suttell method of scoring distortions of Bender designs. The Bender scores were consistent with ultrasonic (sonar) counts of microemboli.  相似文献
