Much of the risk assessment literature has focused on the predictive validity of risk assessment tools. However, these tools often comprise a list of risk factors that are themselves complex constructs, and focusing on the quality of measurement of individual risk factors may improve the predictive validity of the tools. The present study illustrates this concern using the Antisocial Features and Aggression scales of the Personality Assessment Inventory (Morey, 1991). In a sample of 1,545 prison inmates and offenders undergoing treatment for substance abuse (85% male), we evaluated (a) the factorial validity of the ANT and AGG scales, (b) the utility of original ANT and AGG scales and newly derived ANT and AGG scales for predicting antisocial outcomes (recidivism and institutional infractions), and (c) whether items with a stronger relationship to the underlying constructs (higher factor loadings) were in turn more strongly related to antisocial outcomes. Confirmatory factor analyses (CFAs) indicated that ANT and AGG items were not structured optimally in these data in terms of correspondence to the subscale structure identified in the PAI manual. Exploratory factor analyses were conducted on a random split‐half of the sample to derive optimized alternative factor structures, and cross‐validated in the second split‐half using CFA. Four‐factor models emerged for both the ANT and AGG scales, and, as predicted, the size of item factor loadings was associated with the strength with which items were associated with institutional infractions and community recidivism. This suggests that the quality by which a construct is measured is associated with its predictive strength. Implications for risk assessment are discussed.

This article considers the implications of inferentialist philosophy of language for debates in the historiography of philosophy. My intention is to mediate and refine the polemics between contextualist historians and ‘analytic’ or presentist historians. I claim that much of Robert Brandom's nuanced defence of presentism can be accepted and even adopted by contextualists, so that inferentialism turns out to provide an important justification for orthodox history of philosophy. In the concluding sections I argue that the application of Brandom's theory has important limits, and that some polemics by contextualists against presentists are therefore justified.  相似文献

The neuropsychological functioning of 56 children and young adolescents with diagnoses of unipolar depression (n = 17), anxiety disorder (n = 19), or comorbid anxiety/depressive disorder (n = 20) was examined. The neuropsychological profiles of the three groups were parallel, but not equal in level of performance. The three groups displayed similar patterns of performance with profiles suggesting diminished attention abilities. The groups, however, were not equal in level of performance. While subjects with an anxiety or a depressive disorder were similar in level of performance, subjects with a comorbid anxiety/depressive disorder generally performed worse than those with either an anxiety or depressive disorder alone. There was no significant evidence of asymmetrical cerebral dysfunction in any of the diagnostic groups. Results are discussed in relation to adult models of psychopathology with an emphasis on the importance of considering developmental factors when formulating models of childhood psychopathology.  相似文献

Nanometre-scale twins found in the triclinic crystalline phase devitrite, Na2Ca3Si6O16, are shown to exhibit the relatively rare form of twinning, Type II twinning, in which the crystal structure of one of the parts is related to the crystal structure of the other by a rotation of 180° about η 1?=?[1?0?0]. Although formally, the twin plane K 1 is irrational, it is in essence (0?1?0).  相似文献

ABSTRACT

Recalling and imagining autobiographical experiences involves constructing event representations within spatiotemporal contexts. We tested whether generating autobiographical events within a primarily spatial (where the event occurred) or temporal (the sequence of actions that occurred) context affected how the associated mental representation was constructed. We leveraged the well-validated episodic specificity induction (ESI) technique, known to influence the use of episodic processes on subsequent tasks, to develop variants that selectively enhance spatial or temporal processing. We tested the effects of these inductions on the details used to describe past and future autobiographical events. We first replicated the standard ESI effect, showing that ESI enhances generating episodic details, particularly those that are perception-based, when describing autobiographical events (Experiment 1). We then directly compared the effects of the spatial and temporal inductions (Experiment 2 and 3). When describing autobiographical events, spatial induction enhanced generating episodic details, specifically perception-based details, compared to the control or temporal inductions. A greater proportion of the episodic details generated after the temporal induction were gist-based than after the spatial induction, but this proportion did not differ from a control induction. Thus, using a spatial or temporal framework for autobiographical event generation alters the associated details that are accessed.  相似文献

Images and goals     
We propose that mental images are derived from goals. Goals are represented in a complex hierarchy and form a major part of the “working self”. Images reflect the existence of specific goals and also act to maintain goals by facilitating the derivation of beliefs from the content of an image. Images in psychopathology may reflect the operation of dysfunctional goals: goals that are unconstrained and which increase discrepancy (experienced as anxiety) within the goal system. Another feature of the goal system is that it is conservative and avoids change. By this view some aspects of distortions in intrusive images of traumatic experiences might be viewed as a defence against goal change. Conversely generating new images might lead to the formation of new goals. These ideas are applied to the findings of the papers in this special issue of Memory and to several new case studies.  相似文献

The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias.  相似文献

The authors hypothesized that retrieval inhibition in list method directed forgetting could be improved by presenting a task that maximized the segregation step of the retrieval-inhibition process. In Experiment 1, they presented lists of semantically related words in a list method directed-forgetting task to maximize retrieval inhibition. Contrary to predictions, this manipulation eliminated the directed-forgetting effect. The authors further investigated the results of Experiment 1 in Experiments 2 and 3 by manipulating recall instructions and by presenting lists that contained both a categorized and an unrelated list-half. They found directed-forgetting effects for semantically related word lists when participants were asked to recall only the TBR (to-be-remembered) items but not when participants were asked to recall both the TBF (to-be-forgotten) and TBR items. They also found that directed-forgetting effects were not produced when categorized items were presented in the 1st list.  相似文献

We investigated the role of inhibitory control in young children’s human figure drawing. We used the Bear–Dragon task as a measure of inhibitory control and used the classification system devised by Cox and Parkin to measure the development of human figure drawing. We tested 50 children aged between 40 and 64 months. Regression analysis showed that inhibitory control predicted development in human figure drawing even after the effect of age was excluded. These data suggest that inhibitory control plays a role in the development of children’s drawing and imply a relation between the executive functions and representational change.  相似文献

Combining innovation and efficiency is ideal in many organizational settings. Adaptive expertise represents a cognitive explanation of how individuals and teams can learn to achieve simultaneous innovation and efficiency. In 2004, scientists led twin rovers on Mars in the search for historical water. The science team experienced a remarkable increase in efficiency, adapting with flexibility to unexpected events and dynamic, dwindling resources. After discussing the conceptual differences between adaptive expertise and related team learning and innovation concepts, we examine longitudinal behavioral data on novelty, routine and adaptive expertise. Sequential time series ARIMA analyses reveal that novelty fluctuated randomly, but both routine and adaptive expertise significantly increased over time. In addition, novelty, routine expertise, and adaptive expertise did not significantly predict each other directly or at a lag, suggesting that these are indeed three distinct constructs. Implications for theory and research on efficiency and innovation are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
