The objective of the present study was to investigate the comparative criterion‐related validity of different statistical operationalizations of group general cognitive ability (i.e., mean, maximum, and minimum) as a function of task type based on Steiner's (1966, 1972) task typology. In contrast to recent investigations, we hypothesized that, regardless of task type, the mean of group members’ general cognitive ability would predict group performance as well as or better than other statistical operationalizations of group general cognitive ability. We conducted a laboratory study where 157 four‐person groups worked on 4 tasks that conformed to Steiner's typology (additive, compensatory, conjunctive, and disjunctive). The results indicate that the mean was the strongest predictor of group performance across all 4 task types and, in particular, was significantly stronger than the maximum and minimum on both the disjunctive and conjunctive tasks.  相似文献

Because of high levels of risk behavior, adjudicated adolescents are at high risk for negative health outcomes such as nicotine and drug addiction and sexually transmitted diseases. The goal of this article is to examine relationships between future orientation and impulsive-sensation-seeking personality constructs to risk behaviors among 300 adjudicated adolescents. Significant relationships between impulsive sensation seeking and future orientation were found for several risk behaviors. Individuals with more positive future orientation were less likely to use marijuana, hard drugs, alcohol during sex, had fewer alcohol problems, had lower levels of alcohol frequency and quantity of use, and perceived greater risks associated with such behaviors. Higher impulsivity reliably predicted alcohol problems, alcohol use, condom use, and cigarette smoking.  相似文献

The present theory-driven, empirical evaluation examined cross-sectional influences on men’s engagement in risky body change behaviors. The study tested a slightly revised version of the Tripartite Influence Model (Thompson et al. 1999) with a sample of 156 male undergraduate students from the Midwestern Region of the United States. Participants completed measures pertaining to body image and health-risk behaviors. Consistent with the Tripartite Influence Model (Thompson et al. 1999), individual psychological variables mediated the association between sociocultural influences and muscularity-oriented body dissatisfaction. Body dissatisfaction mediated the relation between psychological variables and engagement in body change behaviors. Theoretical models developed to explain body change behaviors among women may be applicable to men when constructs are assessed in ways that are relevant to men.  相似文献

Hooking up on college campuses has become more frequent than dating in heterosexual sexual interaction. Analysis of the relative benefits and costs associated with dating and hooking up suggest that women benefit more from dating while men benefit more from hooking up. U.S students (150 women, 71 men) at a midsized southeastern university indicated preferences for dating and hooking up across a number of situations and indicated the perceived benefits and risks associated with each. As hypothesized, in most situations women more than men preferred dating and men more than women preferred hooking up. Both genders perceived similar benefits and risks to dating and hooking up; differences provided insight into the sexual motives of college women and men.  相似文献

The present study seeks to understand how social comparison information may be used to provide individuals with information about their level of risk and to promote health behavior. The effect of peer comparison information, presented alone or in the context of expert recommendations, was examined across two studies using distinct experimental manipulations. Study 1 showed that regardless of whether expert standards were available or not, participants who were provided with inflated estimates of peer flossing behavior demonstrated increased behavioral intentions and increased flossing behavior measured 3 months later. This pattern was replicated in Study 2 with effects on attitudes toward flossing and intentions to floss. These findings add to a growing literature identifying comparative feedback as distinct from objective information and are discussed in terms of implications for health promotion and risk communication.

This study investigated the social preference and social prominence of 622 5th graders (290 boys, 332 girls) in relation to peer group membership. The sample was recruited from 11 elementary schools in a southeastern state. The ethnicity of participants was 55% European American, 41% African American, and 4% other. Peer groups were classified on each of three domains (academic, aggression, popular) by the proportion of group members who were high on the characteristic of interest. Participants’ peer affiliations were also classified with cluster analytic techniques that yielded distinct configurations of aggression, popularity, and academic competence. Social preference and social prominence were each related to popular peer group type for both boys and girls and differentially related to aggressive and academic group types. Social prominence, but not social preference, was related to peer group configurations for both girls and boys. Implications for the development of social contextual interventions to support students’ adjustment and academic engagement during late elementary school are discussed.  相似文献

Aristotle's typical procedure is to identify four causes of natural changes. Intentional action, a natural change, has standardly been treated as an exception: most think that Aristotle has the standard causalist account, according to which an intentional action is a bodily movement efficiently caused by an attitude of the appropriate sort. I show that action is not an exception to Aristotle's typical procedure: he has the resources to specify four causes of action, and thus to articulate a powerful theory of action unlike any other on offer.  相似文献

Accumulating evidence supports the efficacy of cognitive behavioral therapy for suicide prevention (CBT‐SP) as an empirically supported treatment approach for suicidal patients. In light of these findings, several procedures pulled from CBT‐SP have been recommended for standard care with suicidal patients. The present article provides an overview of the procedures used in CBT‐SP and discusses how these procedures meet, or even exceed, standard of care expectations for outpatient mental healthcare clinicians. Finally, the relevance of clinician fidelity to the CBT‐SP model when evaluating standard of care expectations is discussed.  相似文献

Prison inmates have high prevalence rates for both HIV and AIDS, creating a great need for HIV prevention efforts. We tested the theory of planned behavior (TPB) in 3 domains: intention to engage in condom use when released, intention to not share tattoo equipment in prison, and intention to not share needles or tattoo equipment when released. A total of 478 inmates (87% male) completed TPB and sexual and needle‐use risk behavior measures. TPB constructs accounted for a significant variance in intention to use condoms among African American, Hispanic, and Caucasian inmates, though the strength of the relationships differed by ethnicity. The TPB was less successful for intention to share tattooing equipment and not to share needles or tattoo equipment after release.  相似文献
