J. M. Digman (1997) proposed that the Big Five personality traits showed a higher-order structure with 2 factors he labeled alpha and beta. These factors have been alternatively interpreted as heritable components of personality or as artifacts of evaluative bias. Using structural equation modeling, the authors reanalyzed data from a cross-national twin study and from American cross-observer studies and analyzed new multimethod data from a German twin study. In all analyses, artifact models outperformed substance models by root-mean-square error of approximation criteria, but models combining both artifact and substance were slightly better. These findings suggest that the search for the biological basis of personality traits may be more profitably focused on the 5 factors themselves and their specific facets, especially in monomethod studies. 相似文献

A training paradigm was used to assess the early stages of the acquisition of novel letter strings in adults. Provision of either phonological or semantic information during training improved spelling recognition (Experiment 1). Manipulation of the processing required during training (phonological, semantic, or both) produced no consistent effects on spelling when both phonology and meaning were provided (Experiment 2). An advantage of phonological over orthographic processing on spelling recognition and cued recall was found when meaning was provided during training but phonology was not (Experiment 3). The experiments support the role of phonological information in early learning of orthography, but additional research is required to clarify when and how semantic information supports the formation of new orthographic representations. 相似文献

Syntactic priming is the facilitation of processing that occurs when a sentence has the same syntactic form as a preceding sentence. Such priming effects have been less consistently demonstrated in comprehension than in production, and those that have been reported have depended on the repetition of verbs across sentences. In an event-related potential experiment, subjects read target sentences containing reduced-relative clauses. Each was preceded by a sentence that contained the same verb and either a reduced-relative or a main-clause construction. Reduced-relative primes elicited a larger positivity than did main-clause primes. Reduced-relative targets that were preceded by a main-clause prime elicited a greater positivity than the same target sentences following a reduced-relative prime. In addition, syntactic priming effects were dissociated from effects of lexical repetition at the verb. 相似文献

This pilot study tested a new enactive measure of social information-processing skills and investigated whether preschool children's goals were related to their strategies during hypothetical conflict situations. Children (13 boys, 12 girls) ages 3 to 6 years (three 3-yr.-olds, three 4-yr.-olds, 11 5-yr.-olds, and eight 6-yr.-olds) engaged in a puppet interview of six hypothetical situations. Significant correlations were found between goals and strategies of the adapted version of Chung and Asher's Children's Conflict Resolution Measure, suggesting that preschool children who endorsed friendship goals tended to select more prosocial strategies (.41). Children who endorsed more retaliation goals tended to select more hostile strategies (.67) but fewer prosocial strategies (-.41), and children who endorsed more avoidance goals tended to select more adult-seeking strategies (.45). 相似文献

The use of repeated expressions to establish coreference allows an investigation of the relationship between basic processes of word recognition and higher level language processes that involve the integration of information into a discourse model. In two experiments on reading, we used eye tracking and event-related potentials to examine whether repeated expressions that are coreferential within a local discourse context show the kind of repetition priming that is shown in lists of words. In both experiments, the effects of lexical repetition were modulated by the effects of local discourse context that arose from manipulations of the linguistic prominence of the antecedent of a coreferentially repeated name. These results are interpreted within the context of discourse prominence theory, which suggests that processes of coreferential interpretation interact with basic mechanisms of memory integration during the construction of a model of discourse. 相似文献

In this pilot study we report on proximate outcomes of a 1-hour community gatekeeper training in-service for 76 nonclinical employees in a university hospital workplace setting. Pre-post analyses resulted in positive changes in participants' knowledge about suicide and attitudes (self-efficacy) about intervening with suicidal individuals. A subset of participants engaged in role play practice of gatekeeper skills following training and rated the experience positively. Fifty-five observations were rated using an observational measure developed for this study and approximately half of these demonstrated satisfactory skills post training. Participants in this workplace gatekeeper training reported sharing new knowledge and skills with family, friends, and coworkers. 相似文献

The last decade has witnessed remarkable progress in the understanding of the mammalian cannabinoid system, from the cloning of the endogenous cannabinoid receptor to the discovery of new pharmacologic compounds acting on this receptor. Current and planned studies in humans include compounds with effects ranging from direct antagonists to inhibitors of reuptake and breakdown. This progress has been accompanied by a much greater understanding of the role of the cannabinoid system in modulating the neural circuitry that mediates anxiety and fear responses. This review focuses on the neural circuitry and pharmacology of the cannabinoid system as it relates to the acquisition, expression, and extinction of conditioned fear as a model of human anxiety. Preclinical studies suggest that these may provide important emerging targets for new treatments of anxiety disorders. 相似文献

In the typical population, a series of drawing strategies have been outlined, which progressively emerge during childhood. Individuals with Williams syndrome (WS), a rare genetic disorder, produce drawings that lack cohesion, yet drawing strategies in this group have hitherto not been investigated. In this study, WS and typically developing (TD) groups drew and constructed (from pre‐drawn lines and shapes) a series of intersecting and embedded figures. Participants with WS made use of the same strategies as the TD group for simple intersecting figures, though were less likely to use a typical strategy for more complex figures that contained many spatial relations. When replicating embedded shapes, the WS group used typical drawing strategies less frequently than the TD group, despite attempting to initiate a strategy that is observed in TD children. Results suggested that individuals with WS show a particular difficulty with replicating figures that include multiple spatial relations. The impact of figure complexity and task demands on performance are discussed. 相似文献

Stress has been associated with a variety of chronic and acute conditions and with higher use of health care services. This research reports on 18-month outcomes of a randomized clinical trial of a stress-management program based on the transtheoretical model (TTM; J. O. Prochaska & C. C. DiClemente, 1986). A national sample of 1,085 individuals participated (age range = 18-91 years, M = 55.33; 68.9% female, 31.1% male; 84.8% Caucasian; 15.2% non-Caucasian). Both the treatment and control groups received assessments at 0, 6, 12, and 18 months. In addition to the assessments, the treatment group received 3 individualized reports (0, 3, 6 months) and a manual. The 18-month assessment was completed by 778 individuals (72%). A random effects model indicated that participants completing the study in the treatment group had significantly more individuals reporting effective stress management at follow-up time points than did completers in the control group. Results also indicate that the intervention had significant effects on stress, depression, and specific stress-management behaviors. Results provide evidence for the effectiveness of this TTM population-based stress-management intervention. 相似文献

In the search for ever earlier determinants of adult pathology many ignore the transformative impact of adolescence. The authors suggest that the reality of adolescent development creates a vulnerability to being overwhelmed. Through deferred action childhood experiences may interact with adolescent realities and omnipotent beliefs to traumatize the adolescent. The authors suggest that trauma in adolescence can be independent both of the intensity of current external exposure or of earlier traumatic experiences. 相似文献
