The reciprocal relation between deviant friendships and substance use was examined from early adolescence (age 13-14) to young adulthood (age 22-23). Deviance within friendships was studied using direct observations of videotaped friendship interaction and global reports of deviant interactions with friends as well as time spent with friends. Substance use was assessed through youth self-report at all time points. Multivariate modeling revealed that substance use in young adulthood is a joint outcome of friendship influence and selection processes. In addition, substance use appears to influence the selection of friends in late adolescence. Findings suggest that effective preventions should target peer ecologies conducive to substance use and that treatment should address both the interpersonal underpinnings and addiction processes intrinsic to chronic use, dependence, and abuse. 相似文献

A study was conducted to validate our previous work on the DSM-III-R disorders diagnosed in patients in psychoanalysis in the U.S., Canada, and Australia and to determine which specific mood, anxiety, and personality disorders were the most common in these patients. The earlier study consisted of three surveys of psychoanalytic practice that together obtained data on 1,718 patients, through extensive mail surveys to analysts in the three countries. In the validation study, 206 patients were diagnosed using a different technique. Analysts similar in important respects to those who participated in the original surveys rated patients diagnostically before and after DSM-III-R training. After training, no significant changes appeared in the rates for any of the specific mood disorders. For the thirty disorders examined, training effects decreased the identification of the generalized anxiety disorder, and increased the identification of three personality disorders: avoidant, dependent, and personality disorder not otherwise specified. Thus, analysts slightly underdiagnosed the number of personality disorders, and some "anxious" patients appear to have qualified for personality disorders. Some limitations of the DSM-III-R notion of narcissistic personality are discussed, as are the importance and stability of the self-defeating (masochistic) personality disorder. The most common Axis I disorder in psychoanalytic patients was dysthymia, followed by major depression, recurrent. This study reinforces the findings of the original three surveys. Minor corrections were developed to adjust the original three surveys. 相似文献

The present study examined the dual mediating effects of self-efficacy and self-deception on the relationship between conscientiousness and learning over time. Data from 134 college students were used to investigate the relative impact of self-efficacy and self-deception. Consistent with the hypothesized model, conscientiousness was significantly and positively related to both early training self-efficacy and self-deception, and both self-efficacy and self-deception had significant effects on learning but in opposite directions. Furthermore, the relative impact of self-efficacy and self-deception on learning changed over time as expected. The negative effect of self-deception in early stages of training disappeared at later stages of training but the positive effects of self-efficacy remained. Support was not found for self-efficacy and self-deception as mediators of the conscientiousness-learning relationship. 相似文献

In two experiments, event-related potentials were used to examine the effects of attentional focus on the processing of race
and gender cues from faces. When faces were still the focal stimuli, the processing of the faces at a level deeper than the
social category by requiring a personality judgment resulted in early attention to race and gender, with race effects as early
as 120 msec. This time course corresponds closely to those in past studies in which participants explicitly attended to target
race and gender (Ito &Urland, 2003). However, a similar processing goal, coupled with a more complex stimulus array, delayed
social category effects until 190 msec, in accord with the effects of complexity on visual attention. In addition, the N170
typically linked with structural face encoding was modulated by target race, but not by gender, when faces were perceived
in a homogenous context consisting only of faces. This suggests that when basic-level distinctions between faces and nonfaces
are irrelevant, the mechanism previously associated only with structural encoding can also be sensitive to features used to
differentiate among faces. 相似文献

The priming effect of pseudohomophones was assessed in reading and naming tasks. In two experiments using the fast priming paradigm in reading, there were no pseudohomophone priming effects when the prime duration was 32, 44, or 56 ms from the beginning of a fixation. In a third experiment, using a naming task with isolated words, there were also no pseudohomophone priming effects with prime durations of 32, 44, and 56 ms, but there was with a 200-ms prime duration. The results suggest that pseudohomophone priming doesn't occur at an early stage of reading (in the first 60 ms from the beginning of fixation), but occurs at a later stage (within the first 200 ms). 相似文献

The effects of faking on personality test scores have been studied previously by comparing (a) experimental groups instructed to fake or answer honestly, (b) subgroups created from a single sample of applicants or nonapplicants by using impression management scores, and (c) job applicants and nonapplicants. In this investigation, the latter 2 methods were used to study the effects of faking on the functioning of the items and scales of the Sixteen Personality Factor Questionnaire. A variety of item response theory methods were used to detect differential item/test functioning, interpreted as evidence of faking. The presence of differential item/test functioning across testing situations suggests that faking adversely affects the construct validity of personality scales and that it is problematic to study faking by comparing groups defined by impression management scores. 相似文献

Multidimensional scaling models of stimulus domains are widely used as a representational basis for cognitive modeling. These representations associate stimuli with points in a coordinate space that has some predetermined number of dimensions. Although the choice of dimensionality can significantly influence cognitive modeling, it is often made on the basis of unsatisfactory heuristics. To address this problem, a Bayesian approach to dimensionality determination, based on the Bayesian Information Criterion (BIC), is developed using a probabilistic formulation of multidimensional scaling. The BIC approach formalizes the trade-off between data-fit and model complexity implicit in the problem of dimensionality determination and allows for the explicit introduction of information regarding data precision. Monte Carlo simulations are presented that indicate, by using this approach, the determined dimensionality is likely to be accurate if either a significant number of stimuli are considered or a reasonable estimate of precision is available. The approach is demonstrated using an established data set involving the judged pairwise similarities between a set of geometric stimuli. Copyright 2001 Academic Press. 相似文献

Additive clustering provides a conceptually simple and potentially powerful approach to modeling the similarity relationships between stimuli. The ability of additive clustering models to accommodate similarity data, however, typically arises through the incorporation of large numbers of parameterized clusters. Accordingly, for the purposes of both model generation and model comparison, it is necessary to develop quantitative evaluative measures of additive clustering models that take into account both data-fit and complexity. Using a previously developed probabilistic formulation of additive clustering, the Bayesian Information Criterion is proposed for this role, and its application demonstrated. Limitations inherent in this approach, including the assumption that model complexity is equivalent to cluster cardinality, are discussed. These limitations are addressed by applying the Laplacian approximation of a marginal probability density, from which a measure of cluster structure complexity is derived. Using this measure, a preliminary investigation is made of the various properties of cluster structures that affect additive clustering model complexity. Among other things, these investigations show that, for a fixed number of clusters, a model with a strictly nested cluster structure is the least complicated, while a model with a partitioning cluster structure is the most complicated.

The measurement and development of ethnic identity of Koreans living in the United States and China were examined in the context of different migration experiences. Three hundred sixteen undergraduate college students were administered the Multigroup Ethnic Identity Measure (MEIM; J. S. Phinney, 1992). Separate principal-component analysis for each sample was performed to create cross-culturally equivalent Ethnic Identity and Other-Group subscales. Differential item function analysis revealed no cultural item bias among the retained MEIM items. Korean Americans had higher scores on the Ethnic Identity and Other-Group subscales and were more likely to be classified as bicultural than were Korean Chinese. Korean Chinese were more likely to be classified as assimilated, traditional, or marginalized in their cultural orientation. 相似文献

Little is known about the conditions that lead observers to adopt different inferential goals in the context of their everyday lives. Four studies examined whether future expectations created situational inferential goals. In 2 quasiexperimental studies, students made more situational inferences for targets in their expected future careers. In 2 experiments, situational expectations were manipulated, and participants made more situational inferences when they expected to be in the same situation as the target. This tendency was stronger when observers devoted minimal cognitive effort to their inferences, suggesting that when observers have situational expectations, making situational inferences is less effortful than making dispositional inferences. 相似文献
