The present study investigated the potential mediating effect of adolescents' perceptions of family relationships using a structural equation modeling approach. The sample consisted of 226 immigrant adolescents from the former Soviet Union resettled in a suburban county in the mid-Atlantic region of the U.S. who were selected at random from the local public schools. The study included independent assessment of acculturation to the host (American) and native (Russian) culture. Results confirm the mediational role of family relationships on the impact of Russian acculturation on reduced distress. In addition, family relationships partially mediated the link between American acculturation and reduced psychological distress for these youth. The findings suggest that for this immigrant population native acculturation was related to less distress only when linked to positive familial relationships, whereas American acculturation was related to less distress directly, as well as through its positive impact on familial relationships.  相似文献

Cognitive distortions refer to cognitive processes that are biased and therefore yield dysfunctional and maladaptive products (e.g., interpretation bias). Automatic aspects of information processing need to be considered and investigating these aspects requires forms of assessment other than self-report. Studies focussing on the specificity of cognitive biases across different types of anxiety disorders in childhood are rare. Thus, a forced choice reaction time paradigm with picture stimuli was used to assess the interpretation bias in anxious children online. The study investigated disorder-specific interpretation bias in 71 children with separation anxiety disorder (SAD), 31 children with social phobia, and 42 children without mental disorders, aged 5–13 years. Results indicated that children with SAD rated ambiguous separation pictures as significantly more unpleasant and more arousing than nonanxious children. However, no support was found that children with SAD and social phobia interpret ambiguous separation or social pictures in a more negative way than nonanxious children. Furthermore, no group differences were found in reaction times to all picture categories.  相似文献

In trying to prevent developmental delays, we are continually searching for specific events or factors that are responsible for less than optimal development. Recept attention has focused on the effects of cocaine exposure in utero, with the most common effects appearing to be subtle neurobehavioral differences. The purpose of this study was to determine if, at the age of 6 months, infants exposed to cocaine exhibit significant differences in behavior and cognitive abilities. Results of this study revealed differences between exposed and nonexposed infants in both temperament and behavioral characteristics. Temperamentally, children prenatally exposed to cocaine were reported to be less cooperative, more difficult to manage, and more arrhythmic. The drug-exposed group was also rated lower on behavioral characteristics of responsiveness, communication, and participation. The two groups were similar in terms of cognitive development. The impact of these behavioral effects on the mother-infant relationship is discussed in terms of clinical and research implications of this study.  相似文献

The effects of sex of aggressor and victim (male/female, female/male, male/male, female/female) on judgments regarding sexual aggression on a date were studied. Participants were 415 female and 279 male community college students (M age = 23.0 years; 47.3% European American, 18.6% Latin American, 7.5% African American, 7.8% South East Asian American, 3.7% Asian American, and 15.1% other) who read one of four vignettes describing a date in which forced intercourse occurred. Participants rated degree of disapproval of the aggressor's behavior from their own viewpoint (Participant Rating), the victim's viewpoint (Victim Rating), and the aggressor's viewpoint (Aggressor Rating). Results of 4 × 2 (Vignette × Participant Gender) ANOVAs of Participant Rating and Victim Rating indicated similar disapproval of the aggressor for all couple types except for female aggressor/male victim, for whom disapproval was significantly lower. The aggressor's overall behavior was rated as date/acquaintance rape by 46.6–55.4% of participants for all vignettes except the female aggressor/male victim vignette (18.7%).  相似文献

Traditional approaches to comparing the utility of two tests have not systematically considered the effects of different levels of selectivity that are feasible and appropriate in various selection situations. For example, employers who hope to avoid adverse impact often find they can be more selective with some tests than with others. We conducted two studies to compare the utilities of two tests that differ in costs, validity, and feasible levels of selectivity which can be employed. First, an analytical solution was conducted starting with a standard formula for utility. This analysis showed that for both fixed and variable hiring costs, a higher-cost, lower-validity procedure can have higher utility than a lower-cost, higher-validity procedure when the selection ratios permissible using the two procedures are sufficiently (yet realistically) different. Second, using a computer simulation method, several combinations of the critical variables were varied systematically to detect the limits of this effect in a finite set of specific selection situations. The results showed that the existence of more severe levels of adverse impact greatly reduced the utility of a written test with relatively high validity and low cost in comparison with an assessment center with lower validity and higher cost. Both studies showed that the consideration of selectivity can yield surprising conclusions about the comparative utility of two tests. Even if one test has lower validity and higher cost than a second test, the first may yield higher utility if it allows the organization to exercise stricter levels of selectivity.  相似文献

There is much philosophical literature on the duty to rescue. Individuals who encounter and could save, at relatively little cost to themselves, a person at risk of losing life or limb are morally obligated to do so. Yet little has been said about the other side of the issue. There are cases in which the need for rescue could have been reasonably avoided by the rescuee. We argue for a duty to take rescue precautions, providing an account of the circumstances in which it arises. This novel duty has important implications for public policy. We apply it to the situation of some of the uninsured in the United States. Given the US clinician's duty to provide emergency care to all people regardless of ability to pay, some of the uninsured have a moral duty to purchase health insurance. We defend the duty against objections, including the possibility that a right to rescue can be waived, thus undermining a duty to take rescue precautions, that the duty of many professionals is voluntarily incurred, and that a distinction between actively assumed and passively assumed risks matters morally.  相似文献

Concreteness ratings are frequently used in a variety of disciplines to operationalize differences between concrete and abstract words and concepts. However, most ratings studies present items in isolation, thereby overlooking the potential polysemy of words. Consequently, ratings for polysemous words may be conflated, causing a threat to the validity of concreteness‐ratings studies. This is particularly relevant to metaphorical words, which typically describe something abstract in terms of something more concrete. To investigate whether perceived concreteness ratings differ for metaphorical versus non‐metaphorical word meanings, we obtained concreteness ratings for 96 English nouns from 230 participants. Results show that nouns are perceived as less concrete when a metaphorical (versus non‐metaphorical) meaning is triggered. We thus recommend taking metaphoricity into account in future concreteness‐ratings studies to further improve the quality and reliability of such studies, as well as the consistency of the empirical studies that rely on these ratings.  相似文献

In evaluative conditioning (EC), the pairing of a positively or negatively valenced stimulus (US) with another neutral stimulus (CS) leads to a corresponding change in liking of the CS. EC research so far has concentrated on using unambiguously positive or negative USs. However, attitude objects often possess multiple features that can be positive and negative at the same time. The present research addresses the question of how EC is affected by using such mixed-valence stimuli as USs. In two studies, USs of mixed valence (i.e., positive behavior and membership in a negative group or vice versa) were paired with affectively neutral CSs. Interestingly, results showed that the mixed-valence USs were evaluated according to the valence of the behavioral information. In contrast, the evaluation of associated CSs was more strongly influenced by the valence of the group information that was presented about the USs. Possible explanations as well as implications for EC research are discussed.  相似文献
