Historically, behavior analysis and trait psychology have had little in common; however, recent developments in behavior analysis bring it closer to one of the core assumptions of the trait approach: the stability of behavior over time and, to a lesser extent, environments. The introduction of the concept of behavioral momentum and, in particular, the development of molar theories have produced some common features and concerns. Behavior-analytic theories of stability provide improved explanations of many everyday phenomena and make possible the expansion of behavior analysis into areas that have been inadequately addressed. 相似文献

In this report, we drew on data from an ongoing longitudinal study that began in 1978 (Hauser, Powers, Noam, Jacobson, Weiss, & Folansbee, 1984). Focusing on late, young-adult life among individuals who were psychiatrically hospitalized during adolescence, we examined markers of resilience empirically defined in terms of adult success and well-being. The study includes a demographically similar group recruited from a public high school. Major goals were to (a) develop preliminary models of adaptive functioning among adults in their 30s, (b) examine the extent to which adults with histories of serious mental disorders can be characterized by these models, and (c) explore predictors of successful adult lives from indicators of individuals' psychosocial adjustment at age 25.Results showed significant cohort effects on indexes of adaptive functioning, especially for men. Findings suggest that social relations as well as self-views of competence and relatedness play important roles in characterizing adjustment during the adult years. In addition, indexes of psychosocial adjustment as well as symptoms of psychiatric distress and hard drug use at age 25 made a difference in adult social functioning and well-being, providing hints of possible mechanisms likely to facilitate the ability to "bounce back" after a difficult adolescence. 相似文献

Nonclinical participants watched a trauma film under two processing conditions. During part of the film participants carried out a concurrent visuospatial grounding task consisting of the construction of shapes out of plasticine (modelling clay), while the rest of the film constituted a control, no task condition. The visuospatial task was predicted to selectively compete for processing resources required for intrusive image formation. As predicted, spontaneous intrusive images during the succeeding week were significantly less common from those parts of the film that coincided with the concurrent task. The task had no effect on levels of distress or peritraumatic dissociation, consistent with the hypothesis that intrusions were reduced because the task competed for resources necessary for encoding into an image-based memory system. 相似文献

This study examined whether characteristics of behavioral items reported by parent and child are related to parent–child agreement. Data were collected from 20 judges rating 59 child behaviors on 11 dimensions hypothesized to affect parent–child agreement. Data from 675 parent–child dyads (85% female caregivers, 62% male children, aged 7–17) reporting on 59 child behaviors were used to examine agreement. Behavior characteristics accounted for 43% of variability in parent–child agreement. Three components, saliency to the parent, saliency to the child, and observability/willingness to report, contributed uniquely to prediction of agreement. 相似文献

Reaction time (RT) prior to speech articulation increased as a function of response complexity. The RT findings formed 2 patterns, each of which was a different Response Complexity x Paradigm (choice RT vs. simple RT) interaction. That result extends previous findings from manual button-pressing tasks (S. T. Klapp, 1995) to a different action modality. Two different types of response programming, INT and SEQ, are assumed in the interpretation. Whereas INT can be identified with response programming within a word, SEQ fits a different interpretation related to timing of onsets of speech units. A critical assumption is that a long response is represented as a sequence of chunks; that organization is subject to manipulation. New findings suggest some modifications of the previous theory. 相似文献

95 undergraduates read a simulated crime vignette about either murder or theft in which the perpetrator was a 20-, 40-, or 60-yr.-old man, then gave recommendations about sentence and parole. Subsequently, they made a second set of recommendations for the other crime and another age. For combined sets of judgments, punishment was harsher for the murder than for the theft. For murder, the 60-yr.-old and the 20-yr.-old were both treated more leniently than the 40-yr.-old, but the difference was greater for the older than for the younger offender. Researchers should examine age in relation to judgments for different crimes with participants exposed to all experimental conditions. 相似文献

Studies of agreement commonly occur in psychiatric research. For example, researchers are often interested in the agreement among radiologists in their review of brain scans of elderly patients with dementia or in the agreement among multiple informant reports of psychopathology in children. In this paper, we consider the agreement between two raters when rating a dichotomous outcome (e.g., presence or absence of psychopathology). In particular, we consider logistic regression models that allow agreement to depend on both rater- and subject-level covariates. Logistic regression has been proposed as a simple method for identifying covariates that are predictive of agreement (Coughlin et al., 1992). However, this approach is problematic since it does not take account of agreement due to chance alone. As a result, a spurious association between the probability (or odds) of agreement and a covariate could arise due entirely to chance agreement. That is, if the prevalence of the dichotomous outcome varies among subgroups of the population, then covariates that identify the subgroups may appear to be predictive of agreement. In this paper we propose a modification to the standard logistic regression model in order to take proper account of chance agreement. An attractive feature of the proposed method is that it can be easily implemented using existing statistical software for logistic regression. The proposed method is motivated by data from the Connecticut Child Study (Zahner et al., 1992) on the agreement among parent and teacher reports of psychopathology in children. In this study, parents and teachers provide dichotomous assessments of a child's psychopathology and it is of interest to examine whether agreement among the parent and teacher reports is related to the age and gender of the child and to the time elapsed between parent and teacher assessments of the child.The authors thank the Associate Editor and the referees for their helpful comments and suggestions.

Psychological testing and assessment instruments frequently play a small but important role when psychologists assist the courts as emotional damage experts in personal injury matters. However, examiners frequently, if sometimes inadvertently, mislead the court with test interpretations that are based on clinical rather than forensic populations and that fail to appreciate the lack of robustness of clinical measures in this forensic context. Whereas published computerized interpretations repeatedly remind experts that personality test results should only be used as a method to generate hypotheses about the examinee that are to be subjected to further investigation and consideration, experts all too often inform the courts of test interpretations as if the test results were measures of clinical constructs rather than plaintiffs' self-reports of symptoms. 相似文献

A gray line that rotated about its own center against a stationary background of vertical stripes appeared to double in perceptual speed as it rotated through the vertical position and thus momentarily aligned with the background. Four factors may contribute to this speed-up: (i) landmarks, in which the tip of the moving vertical line moves horizontally across the maximum number of stationary stripes; (ii) orientation repulsion of the moving line by the vertical stripes, which may distort the line's perceived position and hence its perceived speed; (iii) the orientation of an induced brightness pattern along the line; and (iv) the motion of the induced brightness pattern, which moves physically most rapidly along the line when the line is near vertical. To test these possibilities, an annulus display provided landmarks but no intersections, and this almost abolished the effect. A rotating-slit display provided an oriented, moving pattern that mimicked the induced brightness but had no landmarks, and this increased the effect. We conclude that the motion, but not the orientation, of the intersections [option (iv)] was responsible for the illusion. The fact that this motion along the length of the line affected the perceived speed of the line orthogonal to its own length indicates a failure on the part of the visual system to fully decouple tangential from radial motion. 相似文献
