The phenotypic and genetic factor structure of performance on five Multidimensional Aptitude Battery (MAB) subtests and one Wechsler Adult Intelligence Scale—Revised (WAIS-R) subtest was explored in 390 adolescent twin pairs (184 monozygotic [MZ]; 206 dizygotic (DZ)). The temporal stability of these measures was derived from a subsample of 49 twin pairs, with test–retest correlations ranging from .67 to .85. A phenotypic factor model, in which performance and verbal factors were correlated, provided a good fit to the data. Genetic modeling was based on the phenotypic factor structure, but also took into account the additive genetic (A), common environmental (C), and unique environmental (E) parameters derived from a fully saturated ACE model. The best fitting model was characterized by a genetic correlated two-factor structure with specific effects, a general common environmental factor, and overlapping unique environmental effects. Results are compared to multivariate genetic models reported in children and adults, with the most notable difference being the growing importance of common genes influencing diverse abilities in adolescence. 相似文献

The Tennessee Supreme Court's decision in Davis v. Davis, a case that raises the question of how to allocate frozen embryos in the event of divorce, addresses many of the legal issues posed by in vitro fertilization. The decision considers the interests of the progenitors as well as of the children who may result. For example, the court held that gamete providers' discretion regarding the disposition of embryos can be limited only when their decisions would harm the children who might be born. The court also made clear that efforts to seek genetic parenthood are protected only when accompanied by a desire to raise the resulting children, a conclusion that also affects other reproductive technologies. In addition to elaborating an analytic framework, the court set guidelines for resolving disputes when the couples had made no prior agreements, including holding that while the embryos are ex-utero the desire to avoid genetic parenthood almost always trumps the wish to become a parent. The well-reasoned analysis in Davis v. Davis should help shape legal and ethical discussion regarding the use of in vitro fertilization for many years to come. 相似文献

ABSTRACT This study advances the understanding of fear of failure (FF), a dispositional avoidance-oriented achievement motive, by employing interpersonal classification techniques to groups of individuals who fear failure in order to examine the pathoplastic relations between FF and interpersonal problems. Shame-based FF is thought to be related to the self-regulation strategies of appeasement and aggression, and these strategies are hypothesized to be associated with the interpersonal problems of Nonassertiveness and Vindictiveness, respectively. Using 2 independent samples ( n s=60 and 38) reporting high FF, interpersonal profiles were examined for the groups in their entirety and for cluster solutions within the larger samples. Results demonstrated that individuals high in FF exhibited 1 of 2 prototypical interpersonal profiles associated with Domineering/Vindictive or Nonassertive/Exploitable problems that correspond with the hypothesized aggression and appeasement regulation strategies. Consistent with the concept of pathoplasticity, these differences were not better accounted for by demographic, affective, motivational, personality, or attachment style characteristics of the samples. 相似文献

A general factor of personality (GFP) has been proposed as the apex of a personality trait hierarchy that explains covariance among the lower-order factors measured by various personality inventories. In this study we evaluated the GFP hypothesis across several personality inventories, unlike most previous research in which the GFP has been derived from individual instruments in isolation. Exploratory analyses did not produce substantial evidence for the existence of a single cross-instrument higher-order factor of factors and efforts to specify a range of GFP-inspired models in a confirmatory framework led to significant estimation difficulties and poor fit to the data. Overall these results fail to support a common GFP that is positioned at the top of a personality trait hierarchy. 相似文献

Abstract —Concept teaming and learning strategies of pigeons were manipulated in a matching-Co-sample task. Groups of 4 pigeons responded either 0, J, 10, or 20 times to a sample stimulus, and then chose between a matching comparison stimulus and a nonmatching comparison stimulus. Tests with unfamiliar arrangements of the three training stimuli showed that learning was not by if-then rules. Tests with novel stimuli showed that as the number of sample responses increased, learning about the configural pattern of each display gave way to more teaming about the sample-comparison relationship and more concept learning. Pigeons making the most sample responses showed complete concept teaming. 相似文献

Over the past 75 years, the study of personality and personality disorders has been informed considerably by an impressive array of psychometric instruments. Many of these tests draw on the perspective that personality features can be conceptualized in terms of latent traits that vary dimensionally across the population. A purely trait-oriented approach to personality, however, might overlook heterogeneity that is related to similarities among subgroups of people. This article describes how factor mixture modeling (FMM), which incorporates both categories and dimensions, can be used to represent person-oriented and trait-oriented variability in the latent structure of personality. We provide an overview of different forms of FMM that vary in the degree to which they emphasize trait- versus person-oriented variability. We also provide practical guidelines for applying FMM to personality data, and we illustrate model fitting and interpretation using an empirical analysis of general personality dysfunction. 相似文献

The purpose of the present investigation was to examine the psychological impact of remote exposure to the events and aftermath of the terrorist attacks in the USA on September 11th, 2001, and to assess what differences, if any, exist between individuals classified with probable panic disorder and those without. Telephone interviews were conducted with 122 residents of the capital city of the Canadian prairie province of Saskatchewan in spring 2002 in order to gather information regarding current mood, fears and avoidance behaviours as well as current post-traumatic stress disorder symptoms specific to September 11th. Consistent with previous findings and despite the remote nature of exposure, results indicated that the psychological well-being and behaviour of participants with probable panic disorder was more adversely affected by the events and aftermath of September 11th than those without panic disorder. These results suggest that remote viewing of traumatic events can have a significant and lingering impact on psychological well-being and behaviour and that these effects are more pronounced in those with panic disorder. Implications of the findings and future research directions are discussed. 相似文献

Prenatal cocaine and opiate exposure are thought to subtly compromise social and emotional development. The authors observed a large sample of 236 cocaine-exposed and 459 nonexposed infants (49 were opiate exposed and 646 nonexposed) with their mothers in the face-to-face still-face paradigm. Infant and maternal behaviors were microanalytically coded. No opiate-exposure effects were detected. However, mothers of cocaine-exposed infants showed more negative engagement than other mothers. The cocaine-exposed dyads also showed higher overall levels of mismatched engagement states than other dyads, including more negative engagement when the infants were in states of neutral engagement. Infants exposed to heavier levels of cocaine showed more passive-withdrawn negative engagement and engaged in more negative affective matching with their mothers than other infants. Although effect sizes were small, cocaine exposure, especially heavy cocaine exposure, was associated with subtly negative interchanges, which may have a cumulative impact on infants' later development and their relationships with their mothers. 相似文献

In a sample of 162 associate professors of organization science, women in more research-oriented departments had published significantly more during their assistant professor periods than did those in less research-oriented departments, whereas this effect was not observed for men. In more research-oriented departments, men were more likely to have had families (partners and/or dependents) in their assistant professor periods than were women. Patterns in the data suggest that women published more than men in more research-oriented departments but less than men in less research-oriented departments. Findings are discussed in light of person–organization fit theories, gender theories, academic productivity, and gender differences research. 相似文献
