This study uses a multitrait, multimethod (MTMM) approach to investigate the genetic and environmental etiologies of childhood deviant peer affiliation (DPA) and problem behavior (PROB). The variability of genetic and environmental estimates by agent and method is also examined. A total of 77 monozygotic and 72 dizygotic twin pairs and each twin's close friend were assessed. The informants included parents, teachers, and twins, and the methods involved questionnaire reports and coder ratings of videotaped dyadic interactions between each twin and their close friend. Twin intraclass correlations and univariate models attributed DPA and PROB to genetic, and shared and nonshared environmental effects. Parameter estimates differed by rater and method, however. Results accentuate the imperative to attend to method effects inherent in MTMM behavioral geneticresearch. 相似文献

Older adults easily learn probabilistic relationships between cues and outcomes when the predictive event is the occurrence of a cue, but have greater difficulty when the predictive event is the nonoccurrence of a cue (Mutter & Pliske, 1996; Mutter & Plumlee, 2004; Mutter & Williams, 2004). This study explored whether this age-related deficit occurs in a simpler learning context and whether it might be related to working memory (WM) decline. We gave younger and older adults simultaneous discrimination tasks that allowed us to compare their ability to learn deterministic relationships when either the occurrence (feature positive; FP) or the nonoccurrence (feature negative; FN) of a distinctive feature predicted reinforcement. We also included a group of younger adults who performed the discrimination tasks under a concurrent WM load. Both age and WM load had a detrimental effect on initial FP and FN discrimination; however, these effects persisted only in FN discrimination after additional learning experience. Learning predictive relationships requires inductive reasoning processes that apparently do not operate as efficiently in individuals with reduced WM capacity. The impact of WM decline may ultimately be greater for negative cue-outcome relationships because learning these relationships requires more difficult inductive reasoning processes, which place greater demands on WM. 相似文献

The Collaborative Longitudinal Personality Disorders Study (CLPS; Gunderson et al., 2000) was developed to fill gaps in our understanding of the nature, course, and impact of personality disorders (PDs). Here, we review published findings to date, discuss their implications for current conceptualizations of PDs, and raise questions that warrant future consideration. We have found that PDs are more stable than major depressive disorder, but that meaningful improvements are possible and not uncommon. We have confirmed also that PDs constitute a significant public health problem, with respect to associated functional impairment, extensive treatment utilization, negative prognostic impact on major depressive disorder, and suicide risk. At the same time, we have demonstrated that dimensional models of PDs have clinical validity that categories do not, especially greater temporal stability. Furthermore, dimensional personality traits appear to be the foundation of behaviors described by many PD criteria. Taken together, our results lead us to hypothesize that PDs may be reconceptualized as hybrids of stable personality traits and intermittently expressed symptomatic behaviors. 相似文献

Belief-desire reasoning as a process of selection 总被引:7,自引:0,他引:7
Human learning may depend upon domain specialized mechanisms. A plausible example is rapid, early learning about the thoughts and feelings of other people. A major achievement in this domain, at about age four in the typically developing child, is the ability to solve problems in which the child attributes false beliefs to other people and predicts their actions. The main focus of theorizing has been why 3-year-olds fail, and only recently have there been any models of how success is achieved in false-belief tasks. Leslie and Polizzi (Inhibitory processing in the false-belief task: Two conjectures. Developmental Science, 1, 247-254, 1998) proposed two competing models of success, which are the focus of the current paper. The models assume that belief-desire reasoning is a process which selects a content for an agent's belief and an action for the agent's desire. In false belief tasks, the theory of mind mechanism (ToMM) provides plausible candidate belief contents, among which will be a 'true-belief.' A second process reviews these candidates and by default will select the true-belief content for attribution. To succeed in a false-belief task, the default content must be inhibited so that attention shifts to another candidate belief. In traditional false-belief tasks, the protagonist's desire is to approach an object. Here we make use of tasks in which the protagonist has a desire to avoid an object, about which she has a false-belief. Children find such tasks much more difficult than traditional tasks. Our models explain the additional difficulty by assuming that predicting action from an avoidance desire also requires an inhibition. The two processing models differ in the way that belief and desire inhibitory processes combine to achieve successful action prediction. In six experiments we obtain evidence favoring one model, in which parallel inhibitory processes cancel out, over the other model, in which serial inhibitions force attention to a previously inhibited location. These results are discussed in terms of a set of simple proposals for the modus operandi of a domain specific learning mechanism. The learning mechanism is in part modular--the ToMM--and in part penetrable--the Selection Processor (SP). We show how ToMM-SP can account both for competence and for successful and unsuccessful performance on a wide range of belief-desire tasks across the preschool period. Together, ToMM and SP attend to and learn about mental states. 相似文献

A sample of 92 male evangelical missionary personnel completed Form G (Anglicised) of the MBTI. The two predominant types among this group were ESTJ (24%) and ISTJ (15%). In the group as a whole there were clear preferences for extraversion over introversion, for sensing over intuition, for thinking over feeling, and for judging over perceiving. 相似文献

The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992b) has been criticized for the absence of validity scales designed to detect response distortion. Recently, validity scales were developed from the items of the NEO-PI-R (Schinka, Kinder, & Kremer, 1997) and several studies have used a variety of methods to test their use. However, it is controversial whether these scales are measuring something that is substantive (such as psychopathology or its absence) or stylistic (which might be effortful distortion or less conscious processes such as lack of insight). In this study, we used a multimethod-multitrait approach to examine the validity of these scales in a clinical sample of 668 participants diagnosed with personality disorders or major depression. Using various indicators of both stylistic and substantive variance, confirmatory factor analyses (CFA) suggested that these validity scales measure something that may be conceptually distinct from, yet highly related to, substantive variance in responding. 相似文献

This study examined the effects of multiple risk, promotive, and protective factors on three achievement-related measures (i.e., grade point average, number of absences, and math achievement test scores) for African American 7th-grade students (n = 837). There were 3 main findings. First, adolescents had lower grade point averages, more absences, and lower achievement test scores as their exposure to risk factors increased. Second, different promotive and protective factors emerged as significant contributors depending on the nature of the achievement-related outcome that was being assessed. Third, protective factors were identified whose effects were magnified in the presence of multiple risks. Results were discussed in light of the developmental tasks facing adolescents and the contexts in which youth exposed to multiple risks and their families live. 相似文献

People served by mental health providers represent diverse cultural groups. In-depth qualitative interviews were used to collect data to examine: “How do people, diagnosed with a mental illness, perceive their experience in a partial care mental health program from the perspective of their cultural context?” Four participants described cultural identities that included ethnic, health status, and sexual orientation identities. The participants' way of participating in the world was often in conflict with cultural values and expectations of the family and counselors. Cultural competence must include understanding how complex, multiple cultural contexts interact and influence a person's participation in the therapeutic process. 相似文献

Abstract Intensive multiple family group therapy combines the advantages of group therapy with those of time-limited, goal-oriented approaches. Using the Redecision Family Therapy model further refines the technique by integrating the seemingly disparate methods of intrapsychic and systemic therapy. In this paper we describe our 10-year experience with this model, elaborate on the model itself and discuss the results of an outcome survey. 相似文献

Abstract This paper presents a pilot project that was developed to work with small groups of couples in which the women were pregnant with their first child. The primary purpose was to stimulate couples to become aware of their communications and support systems as the necessary building blocks for healthy family emotional development. Pregnancy can be seen as a transitional period leading to another life stage in the growth of an individual. The format, topics, evaluation and summary are presented with the hope that other mental health professionals will be motivated to develop similar groups. 相似文献
