The purpose of this study is twofold. First, it aims to examine whether the impairment in peer functioning and social-cognitive deficits (i.e., hostile attribution bias, social comprehension, social problem-solving) found in elementary school aged children with ADHD also occur in adolescence. Second, it aims to provide evidence for a predictive relationship between these social-cognitive deficits and an adolescent’s functional impairment in the social domain. To address these aims, several social-cognitive tasks were administered to a small sample of young adolescents with ADHD (N = 27) and a comparison sample without an ADHD diagnosis (N = 18). Parent report of functional impairment and peer sociometric data were also gathered. Comparisons of both parent and peer report of adolescent social functioning suggest that individuals with ADHD continue to experience difficulties with peers into the adolescent years and data from the social-cognitive tasks show evidence of social comprehension and problem-solving deficits. Further analyses indicated a significant link between functional impairment and social cognition. Findings herein are discussed in the context of both the developmental changes that arise during adolescence and consideration of the importance of social cognition for understanding the impaired social functioning experienced by adolescents with ADHD.  相似文献

Suicide and non-suicidal self-injurious behavior (NSSI) continue to be significant health problems for adolescents. Although there are many instruments available to assess self-harm behaviors, few have been validated for use with adolescents, and even fewer have been validated for use with different racial/ethnic groups. The Self-Harm Behavior Questionnaire (SHBQ) assesses NSSI, suicidal ideation, suicide threats, and past suicide attempts. Data from 1,386 racially/ethnically diverse adolescents (57.5% minority) were collected to examine the validity of the SHBQ in this age group. Analyses supported the four-factor structure, revealed the SHBQ is internally consistent, and provided evidence for convergent validity within Caucasian, African American, and Hispanic adolescents. However, slight differences were noted. Overall, the findings suggest the SHBQ is a useful assessment tool appropriate for use with Caucasian, African American, and Hispanic adolescents.  相似文献

We examine how emotion (anger and happiness) affects value claiming and creation in a dyadic negotiation between parties with unequal power. Using a new statistical technique that analyzes individual data while controlling for dyad-level dependence, we demonstrate that anger is helpful for powerful negotiators. They feel more focused and assertive, and claim more value; the effects are intrapersonal, insofar as the powerful negotiator responds to his or her own emotional state and not to the emotional state of the counterpart. On the other hand, effects of emotion are generally not intrapersonal for low-power negotiators: these negotiators do not respond to their own emotions but can be affected by those of a powerful counterpart. They lose focus and yield value. Somewhat surprisingly, the presence of anger in the dyad appears to foster greater value creation, particularly when the powerful party is angry. Implications for the negotiation and power literatures are discussed.  相似文献

When humans and animals estimate numbers of items, their error rate is proportional to the number. To date, however, only humans show the capacity to represent large numbers symbolically, which endows them with increased precision, especially for large numbers, and with tools for manipulating numbers. This ability depends critically on our capacity to acquire and represent explicit symbols. Here we show that when rhesus monkeys are trained to use an explicit symbol system, they too show more precise, and linear, scaling than they do using a one-to-one corresponding numerosity representation. We also found that when taught two different types of representations for reward amount, the monkeys systematically undervalued the less precise representation. The results indicate that monkeys, like humans, can learn alternative mechanisms for representing a single value scale and that performance variability and relative value depend on the distinguishability of each representation.  相似文献

Association studies of the serotonin transporter promoter polymorphism (5-HTTLPR) and negative emotionality (NE) are inconclusive. However, emerging evidence suggests that the association between this polymorphism and NE may be influenced by levels of another temperament trait, positive emotionality (PE). Therefore, this study examined whether the association between the 5-HTTLPR and NE was moderated by PE. A community sample of 413 three-year-old children completed a standardized battery of laboratory tasks designed to tap temperamental emotionality. Children were also genotyped for the 5-HTTLPR. No direct association between 5-HTTLPR genotype and NE was found. However, the interaction of child PE and NE predicted 5-HTTLPR genotype. Furthermore, children with a short allele who were also low in PE had significantly greater NE than children without a short allele or children with high PE. Our findings suggest that the short allele of the 5-HTTLPR is associated with NE only in the context of low PE. Inconsistent links between NE and this gene in previous research may stem from the failure to consider other temperament traits that moderate associations.  相似文献

Why, during a decision between new alternatives, do people bias their evaluations of information to support a tentatively preferred option? The authors test the following 3 decision process goals as the potential drivers of such distortion of information: (a) to reduce the effort of evaluating new information, (b) to increase the separation between alternatives, and (c) to achieve consistency between old and new units of information. Two methods, the nonconscious priming of each goal and assessing the ambient activation levels of multiple goals, reveal that the goal of consistency drives information distortion. Results suggest the potential value of combining these methods in studying the dynamics of multiple, simultaneously active goals.  相似文献

This article will compare and contrast two very different accounts of convention: the game-theoretical account of Lewis in Convention, and the account initially proposed by Margaret Gilbert (the present author) in chapter six of On Social Facts, and further elaborated here. Gilbert’s account is not a variant of Lewis’s. It was arrived at in part as the result of a detailed critique of Lewis’s account in relation to a central everyday concept of a social convention. An account of convention need not be judged by that standard. Perhaps it reveals the nature of an important phenomenon. Looked at in that light, these very different accounts are not incompatible. Indeed, neither should be ignored if one is seeking to understand the way in which human beings arrive at some degree of social order.  相似文献

Two studies explored the stability of art preference in patients with Alzheimer's disease and age-matched control participants. Preferences for three different styles of paintings, displayed on art postcards, were examined over two sessions. Preference for specific paintings differed among individuals but AD and non-AD groups maintained about the same stability in terms of preference judgments across two weeks, even though the AD patients did not have explicit memory for the paintings. We conclude that aesthetic responses can be preserved in the face of cognitive decline. This should encourage caregivers and family to engage in arts appreciation activities with patients, and reinforces the validity of a preference response as a dependent measure in testing paradigms.  相似文献

Two studies of college students in the US utilized a new methodological approach in which participants arranged their multiple family members (i.e. parents, siblings, aunts, and uncles) within a series of relationship network grids. These grids measured participants’ own feelings of communal responsiveness toward and perceived feelings of communal responsiveness from each family member relative to one another. The results of Study 1 (N = 86) and Study 2 (N = 111) supported the hypotheses that (1) people perceive more responsiveness from female family members than from male family members and (2) people feel more responsive toward female than toward male family members. Study 2 provided evidence that these associations were mediated by felt and perceived intimacy, dependence, and obligation, but not liking.  相似文献

Our research examines whether intersecting racial and gender identities affect person perception. Predominantly White undergraduates (292) from a large northeastern U.S. university categorized and rated pictures (Study 1) and videos (Study 2) of Black and White men and women. We supported three hypotheses: 1) intersectionality affects person perception processes, leading to gender categorization errors for Black women; 2) “Blackness” and “maleness” are highly associated for Black male and female targets; and, 3) women are perceived as unattractive proportionally to their perceived masculinity, leading Black women to be rated as less attractive than other women. We suggest that intersectional approaches are required in order to fully understand person perception. Further, the Black/male association may lead to unique harms for Black women.  相似文献
