This study explores where and when community violence exposure (CVE) matters for psychological functioning in a sample of low-income, racial/ethnic minority youth (M) age = 16.17, 55% female, 69% Black, and 31% Non-Black/Latinx) living in Chicago. CVE was measured with violent crime data that were geocoded in terms of distance from youths’ home and school addresses, and then calculated in terms of three distinct spatial dynamics: chronicity, pervasiveness, and spatial proximity. These measures reflect indirect/objective CVE across different conceptualizations of time, space, and neighborhood context. We tested the relationship between each CVE measure and trait anxiety and behavioral and cognitive dysregulation while controlling for youth-reported, direct violent victimization (e.g., being attacked) to examine how indirect/objective CVE occurring within youths’ neighborhood contexts matters beyond direct/subjective violence exposure. Results revealed that long-term chronic, pervasive, and spatially proximal CVE was related to higher levels of behavioral dysfunction. In contrast, CVE within home- and school-based neighborhoods interacted to predict trait anxiety; youth living in low-crime neighborhoods and attending schools in high-crime neighborhoods had the highest rates of trait anxiety. Measuring CVE within both home and school neighborhoods at specific spatial measurements and time frames is critical to understand and prevent the consequences of CVE. 相似文献

Shared care between parents and grandparents is common in Asian cultures. This cocare practice provides many benefits to families but is also particularly complex, as both parents and grandparents must simultaneously fulfill their roles as cocaregivers as well as maintain their relationship with each other. This study aims to explore the determinants of coparenting relationships between parents and grandparents in Vietnam. Data were collected from 501 Vietnamese parents whose aging parents are active carers for their children. The results indicated that grandparent psychological control and parent–grandparent quality of communication explain the largest variance in both parent–grandparent coparenting conflict and cooperation. The results suggest that parenting interventions aimed at the Asian cultures, where grandparent care is common, may benefit from the inclusion of a content focus on promoting the coparenting relationship between parents and grandparents. 相似文献

The current applied research on African-American women is characterized by a limited focus on primarily poor and single mothers and comparative studies with white women. The resulting research ignores the diversity within African-American women generalizing from noncomparative or restrictive samples to all African-American women and provides narrowly focused and/or inappropriate research models in which to study the development of these women across the life span. This review focuses on some of this research as it relates to social context factors in African-American women's lives: social supports and parenting, work and self-esteem, gender role attitudes and marital life, and mental health. An examination of methodological problems and suggestions for future research is discussed. 相似文献

Tyrosine hydroxylase (TH) activity was measured in brains from Norway rats and silver foxes showing wild type aggressiveness and from their counterparts selected over 20-25 generations for reduced aggressiveness towards humans (tameness). TH activity in the brain stem and cortex was increased in tame animals of both species compared with aggressive counterparts. Selection increased hypothalamic TH activity in foxes, but decreased it in rats. There was no difference in TH activity in corpus striatum between the tame and aggressive animals. Fetal TH activity in the posterior part of the brain was higher in tame than aggressive rats at day 20 of embryogensis. Increased TH activity in the brain stem and cortex of adult aggressive rats was observed after treatment of their mothers with hydrocortisone on the days 16 and 18 of pregnancy. This elevation in TH activity was associated with attenuation of the defense behavior of aggressive rats. The data suggested that alterations in neural TH activity in tame rats and foxes may be part of the neurochemical basis of their behavioral phenotype which is developed by selection. © 1994 Wiley-Liss, Inc. 相似文献

One way of identifying emotional behaviors across species, language, and cultures is to describe the “instrumental” effects of each particular behavior. Since aggression and defense may be instrumental they also represent coping behavior. The term coping is being used partly to indicate whether or not the behavior is successful and partly to describe how a situation is being handled (coping strategies). This review deals with how these behaviors are observed and quantified in humans and how they are linked to physiological changes. The internal state of the individual is decided by the expectancy of the outcome of a given situation, but each behavior strategy may have specific links to particular brain mechanisms and particular physiological effectors. © 1995 Wiley-Liss, Inc. 相似文献

The attacks by resident lactating Wistar rats on sexually naive conspecifics of both sexes were examined. Male and female intruders were equally attacked in terms of frequency and number of bites, but the topographies of biting seen in these encounters were different. Similarly to male-male agonistic interactions, females were attacked in a fashion which avoided bites to the head and snout (“offensive” attack), whereas males were frequently bitten on such vulnerable regions (“defensive” attack). This dichotomy in bite pattern suggests that different motivations and functions underlay maternal aggression in these situations. The defensive attack on males may be a deterrent to infanticide since only male intruders counterattack lactating females and kill their pups. The attack on females may be concerned with resource competition. 相似文献

Issues in Assessing Psychological Characteristics at a Distance: An Introduction to the Symposium 总被引:1,自引:1,他引:0
Mark Schafer 《Political psychology》2000,21(3):511-527
This article provides an overview of the issues, methods, and constructs presented in the papers for the symposium Issues in Assessing Psychological Characteristics at a Distance. These papers share a substantive focus on the psychological characteristics of U.S. presidents and a common commitment to the use of 'at-a-distance' assessment techniques. In this context, at-a distance measures raise several substantive and methodological issues, including the connections between leaders and advisors, the value of public versus private rhetoric, and differences between spontaneous and prepared source material. The authors of the papers use two psychological constructs, the operational code and conceptual complexity, to investigate these issues and to illustrate the utility of at-a-distance methods for assessing psychological characteristics. 相似文献

Psychological characteristics of women with eating disorders: Permanent or transient features? 总被引:1,自引:0,他引:1
The purpose of the study was to make a psychological profile of Danish women with Eating Disorders, who were not currently hospitalized. 75 women between the ages of 19 and 46 years participated. 22 participants suffered from a clinical eating disorder (ED). 20 women had previously suffered from a clinical ED, and 33 women had never suffered from ED. The study included sociodemographic data, problems in relation to eating and weight, exposure to stressful life events, and the following questionnaires: The Eating Disorder Inventory, the Rosenberg Self-Esteem Scale, the Coping Styles Questionnaire, the Perceived Stress Scale, the Defense Style Questionnaire, and the Trauma Symptom Checklist. Psychologically, women with ED differed significantly from women without ED by using a more primitive defense style, perceiving themselves as being more exposed to stress, using more inefficient methods of coping and having lower self-esteem. Unexpectedly, the study also showed that recovery from an ED was resulting in normalisation of both behavioral and psychological characteristics. The implications of these findings are discussed. 相似文献
