The Pd, K and L scales of the MMPI and four of Kolberg's Moral Judgment Situations were administered to three criterion groups; adolescent delinquents, college students, and individuals belonging to a therapy collective which provides free community service. Greater than 50% of both the delinquent and therapy collective subjects were classified as psychopathic, (Pd + K T score > 70). The three subject groups obtained significantly different moral maturity scores with the therapy collective subjects receiving the highest moral maturity mean score. The results of two stepwise regression analyses found no relationship between Pd scores and moral maturity scores.  相似文献

Predicting the attitudes of a powerful out-group can influence attitude strength and the perceived status of in-group members. American farmers indicated their own attitude positions on eight issues relevant to conflict with the Environmental Protection Agency (EPA), and then estimated the positions either of their in-group, the EPA, a control out-group, or participated in a no-estimation control condition. The estimation of attitude disagreement with EPA agents elicited negative thoughts about their power and control which mediated a decrease in self-certainty. Assumed attitude contrast also diminished the perceived status of farmers. Discussion focuses on relational and instrumental sub-group connections.  相似文献

The article discusses the application of the ideas of evidence-based medicine or empirically supported treatment to the field of psychoanalysis. The author argues that empirical support is gradual rather than categorical, and that the randomized clinical trial (RCT), which is commonly heralded as the appropriate method of support, confounds patient suitability factors with treatment 'as such'. As a consequence of the exclusive reliance on the RCT, empirical validation of psychological treatments has generally favoured cognitive-behavioural treatments, although there is ample evidence - albeit non-RCT - for the beneficial effects of short-term and long-term psychoanalytic treatment. The author argues for a suitability matching approach to empirical validation, where each treatment is tested, as powerfully as feasible, on samples based on selfselection (patient's choice, clinical assignment, suitability judgments etc.). The paper concludes by referring to two recent studies, indicating that there is reason to evaluate alleged empirical support with caution.  相似文献

Method effects often occur when constructs are measured by different methods. In traditional multitrait-multimethod (MTMM) models method effects are regarded as residuals, which implies a mean method effect of zero and no correlation between trait and method effects. Furthermore, in some recent MTMM models, traits are modeled to be specific to a certain method. However, often we are not interested in a method-specific trait but in a trait that is common to all methods. Here we present the Method Effect model with common trait factors, which allows modeling “common” trait factors and method factors that represent method “effects” rather than residuals. The common trait factors are defined as the mean of the true-score variables of all variables measuring the same trait and the method factors are defined as differences between true-score variables and means of true-score variables. Because the model allows estimating mean method effects, correlations between method factors, and correlations between trait and method factors, new research questions may be investigated. The application of the model is demonstrated by 2 examples studying the effect of negative, as compared with positive, item wording for the measurement of mood states.  相似文献

With data from the middle cohort of the Pittsburgh Youth Study, a prospective longitudinal study of inner-city boys, we examined whether Big Five agreeableness facets could be reliably recovered in this sample, and whether facets predicted educational, occupational, social, and antisocial life outcomes assessed a decade later. Caregivers described their adolescent boys’ personalities using the Common California Q-Set; twelve years later, participants were interviewed and court records were obtained. Factor analyses recovered two facets: compliance and compassion. Compliance predicted more schooling and lower risk of unemployment, teenage fatherhood, and crime; compassion related to longer committed relationships. Findings highlight the value of studying personality at the facet level.  相似文献

Abstract

The short-term memory for spatial frequency information was assessed by measuring the spatial frequency discrimination thresholds for briefly flashed luminance gratings as a function of the time interval between the test and reference gratings, using a computer-controlled two-interval forced-choice procedure. Discrimination thresholds were stable for interstimulus intervals in the range 1–30 sec under all conditions tested. At low contrasts, short exposure times and low spatial frequencies discrimination thresholds increased, but no interactions between stimulus parameters affecting thresholds and interstimulus interval were observed. It is concluded that factors limiting spatial discrimination are associated with the sensory coding stage. Spatial discrimination and visual memory may be based on a common representation, which is perfectly retained in short-term memory. Visual half-field tests revealed no hemispheric differences in the processing and retention of spatial frequency information.  相似文献

Irritable bowel syndrome is a common disorder that can be associated with significant disability and health care costs. Beyond it is the most common disease diagnosed by gastroenterologists. Diagnosis is based on typical complaints including abdominal pain, bloating, irregularities of bowel movements and defecation. The discussion of different etiopathogenetic models showed that irritable bowel syndrome is a biopsychosocial disorder in which psychosocial factors, altered motility and visceral hypersensitivity interact. When symptoms are moderate to severe and are associated with psychological distress and impaired quality of life, psychological treatments can be considered. Apart from symptomatic treatment with loperamide for diarrhoea and antidepressants for abdominal pain and comorbid psychological symptoms for example cognitive behavioral treatment, hypnotherapy, psychodynamic short-term psychotherapy and functional relaxation are being evaluated.  相似文献

Zusammenfassung Die funktionelle Bedeutung kommissuraler Systeme für den visuellen interhemisphärischen Informationsaustausch wurde bei 71 Tauben an monokular gelernten Zweifachwahlen geprüft (instrumentale Konditionierung nach Skinner). 1 Farb- und 4 Form-Diskriminationen (2 oben-unten- und 2 links-rechts-symmetrische Spiegelbildpaare) wurden verwendet. Bei 21 Tauben war die Decussatio supraoptica (DSO) stereotaktisch durchtrennt worden, bei 20 waren die Commissura tectalis (CT) und die Commissura posterior (CP) durchschnitten. Bei 11 Tauben waren alle 3 Verbindungen unterbrochen. Das Ausmaß der Läsionen wurde durch histologische Kontrolle verifiziert. Der interhemisphärische Transfer war nach DSO-Durchtrennung bei der Farb- und den oben-unten-symmetrischen Formzweifachwahlen stark vermindert. Der Transfer sämtlicher Zweifachwahlen war nach CT+CP-Durchtrennung nicht signifikant verschieden von dem der Kontrolltiere. Es wurde erstmals gezeigt, daß mindestens ein Teil der DSO-Fasern bei Vögeln visuelle Information von einer Hirnhälfte zur andern übermittelt.
Interhemispheric transfer of two-choice discrimination in commissurotomized pigeons
Summary The role of avian commissural systems in interhemispheric transfer of monocularly learned visual discriminations was investigated in an instrumental conditioning situation (Skinner). Color and pattern (up-down and left-right mirror-images) were used as stimuli. Stereotaxic lesions were placed in the supraoptic decussation of 21 pigeons, in the tectal and posterior commissures of 20 pigeons. In 11 animals all three connections were interrupted. All lesions were histologically verified. After section of the supraoptic decussation interhemispheric transfer was severely impaired for one color and two up-down mirror-image discriminations. No significant impairment in transfer for color, up-down and left-right mirror-image discriminations followed section of the tectal and posterior commissures. These data demonstrate that at least part of the supraoptic decussation is involved in interhemispheric transfer of visual information.
