We show that a single presentation of a zebra finch song, 2 s in duration, will induce an "immediate-early gene" response in the caudomedial neostriatum of zebra finches (Poephila guttata). Repetition of this stimulus 10 times is sufficient to induce a maximal increase in RNA and protein, detected 30 and 90 min later respectively. Thus very brief stimuli can set in motion a slow genomic process in the brain which takes hours to resolve. Immediate-early gene function is often considered in the context of a "feedback" model (i.e., to consolidate memories of the inducing event). However, based on the long lag observed here between initiation and full expression of the molecular response, we suggest an alternative, ethologically based, "feed-forward" model in which exposure to a novel or significant context triggers an increase in the efficiency of memory capture processes for subsequent experiences. 相似文献

Individuals with fibromyalgia are at greater risk for depressive symptoms than the general population, and this may be partially attributable to physical symptoms that impair day-to-day functioning. However, individual-level protective characteristics may buffer risk for psychopathology. For instance, the ability to perceive a “silver lining” in one’s illness may be related to better mental and physical health. We examined perceived silver lining as a potential moderator of the relation between fibromyalgia impact and depressive symptoms. Our sample of persons with fibromyalgia (N = 401) completed self-report measures including the Fibromyalgia Impact Questionnaire-Revised, Depression Anxiety Stress Scales, and the Silver Lining Questionnaire. Moderation analyses covaried age, sex, and ethnicity. Supporting hypotheses, increasing impact of disease was related to greater depressive symptoms, and perceptions of a silver lining attenuated that association. Despite the linkage between impairment and depressive symptoms, identifying positive aspects or outcomes of illness may reduce risk for psychopathology. Therapeutically promoting perception of a silver lining, perhaps via signature strengths exercises or a blessings journal, and encouraging cognitive reframing of the illness experience, perhaps via Motivational Interviewing or Cognitive Behavioral Therapy, may reduce depressive symptoms in persons with fibromyalgia. 相似文献

Personality matters for romantic relationships. In this study, we investigated personal growth in couples (the Michelangelo phenomenon) and targeted questions of personality effects. We explored whether traits intrapersonally predict ideal selves as well as whether traits intra- and interpersonally account for why some people are more likely to benefit from the Michelangelo phenomenon than others. We used data from a 4-year study of 163 couples (Mage = 50.72 years). Logistic regressions indicate complementarity effects for men, in that those high in neuroticism were likely to wish to be emotionally stable. Actor–partner interdependence models revealed positive actor effects of emotional stability, extraversion, and agreeableness, while few partner effects emerged. We discuss dyadic personal growth in view of individual trait differences. 相似文献

The Dark Factor of Personality (D) has been suggested as the basic disposition underlying dark traits, thereby representing their common core. However, it has also been argued that such commonalities reflect the low pole of Agreeableness. The present study (N = 729) employed five established inventories to model the Agreeableness construct and considered seven theoretically derived criterion variables, including one behavioral outcome. Results indicate that Agreeableness and D exhibit a substantial, but far from perfect, association of r = −.64. Further, D incrementally improved the prediction of all but one criterion measure. These results speak against the notion that the commonalities of dark traits can be reduced to low Agreeableness and rather support the contention to consider Agreeableness and D as functionally distinct constructs. 相似文献

The authors translated the California Brief Multicultural Competence Scale (CBMCS; Gamst et al., 2004), a measure of multicultural competence, into Korean for cross-cultural validation. An exploratory factor analysis followed by a confirmatory factor analysis on a sample of Korean counselors (N = 365) supported a 3-factor model: Multicultural Ability, Multicultural Knowledge, and Multicultural Awareness. The Korean version was deemed to possess sound psychometric properties, such as high test-retest reliability and criterion-related validity. Los autores tradujeron al idioma coreano la Escala Breve de Competencia Multicultural de California (CBMCS, por sus siglas en inglés; Gamst et al., 2004), un instrumento de medida de competencia multicultural, para su validación intercultural. Un análisis factorial exploratorio seguido de un análisis factorial confirmatorio sobre una muestra de consejeros coreanos (N = 365) respaldó un modelo de 3 factores: Habilidad Multicultural, Conocimiento Multicultural y Conciencia Multicultural. Se concluyó que la versión en coreano tenía propiedades psicométricas sólidas, como una alta fiabilidad de la repetición de las pruebas y una alta validez de criterio. 相似文献

Although a statistical model might fit well to a large proportion of the individuals of a random sample, some individuals might give ‘unusual’ responses that are not well explained by the hypothesized model. If individual responses are given as continuous response vectors, M-distances can be used to produce real valued indicators of how well an individual's response vector corresponds to a covariance structure implied by a psychometric model. In this note, we focus on the so-called one-factor model. Two M-distances, dsi and dri, which are sensitive to different aspects of the assumed factor model, have been proposed. While one of the M-distances, dri, has been derived based on Bartlett factor scores, in this note we show that the second M-distance, dsi, can be derived in an analogous fashion based on Thomson factor scores. 相似文献

The post-traumatic growth (PTG) model proposes that cognitive processing is a key mechanism that leads to growth in the aftermath of traumatic events. Building upon the PTG model, the present study examined the paths from the disruption of core beliefs to post-traumatic stress symptoms (PTSS) and PTG via intrusive and deliberate rumination. The sample includes 370 Korean undergraduate students who reported at least one highly stressful experience in their lifetime. Structural equation modeling demonstrated that disruption of core beliefs predicted PTG both directly and indirectly through multiple pathways: via deliberate rumination, intrusive rumination, and the path from intrusive to deliberate rumination. The disruption of core beliefs positively predicted PTSS only through intrusive rumination. No bivariate relationship was found between PTSS and PTG. These findings support the different roles of intrusive rumination and deliberate rumination in mediating the paths from disruption of core beliefs to PTSS and PTG. Implications and limitations of this study were discussed. 相似文献
