An integrative typology of personality assessment for aggression: implications for predicting counterproductive workplace behavior 总被引:2,自引:0,他引:2
Bing MN Stewart SM Davison HK Green PD McIntyre MD James LR 《The Journal of applied psychology》2007,92(3):722-744
This study presents an integrative typology of personality assessment for aggression. In this typology, self-report and conditional reasoning (L. R. James, 1998) methodologies are used to assess 2 separate, yet often congruent, components of aggressive personalities. Specifically, self-report is used to assess explicit components of aggressive tendencies, such as self-perceived aggression, whereas conditional reasoning is used to assess implicit components, in particular, the unconscious biases in reasoning that are used to justify aggressive acts. These 2 separate components are then integrated to form a new theoretical typology of personality assessment for aggression. Empirical tests of the typology were subsequently conducted using data gathered across 3 samples in laboratory and field settings and reveal that explicit and implicit components of aggression can interact in the prediction of counterproductive, deviant, and prosocial behaviors. These empirical tests also reveal that when either the self-report or conditional reasoning methodology is used in isolation, the resulting assessment of aggression may be incomplete. Implications for personnel selection, team composition, and executive coaching are discussed. 相似文献

The Influence of Affect on Goal Choice and Task Performance 总被引:1,自引:0,他引:1
The present study investigated the influence of mood on self-set goals and task performance. Results from 2 studies suggest a restricted view of mood effects in which affective state influences the level of self-set goals or task performance, but not both. Study 2 reveals asymmetrical mood effects on task performance, with positive- and negative-mood participants exceeding the baseline performance of neutral mood participants. Evidence indicates that goal-setting instructions may alter how individuals interpret motivational implications of mood. Although theory implies an inclusive view in which mood has both direct and indirect (through goal-setting) performance effects, the conflicting influences of affect infusion at different points of the goal-striving process may diminish the likelihood of observing inclusive effects. 相似文献

This study explored relationships between perceptions of intra-team communication and role ambiguity within an interdependent team sport environment. Participants were 116 intercollegiate-level team sport athletes ( M age = 20.6 years). For males, the intra-team communication dimension of acceptance was found to predict the majority of role ambiguity dimensions for both performance contexts of offense and defense (.09 ≤ R 2 adj. ≤ .16). However, limited support for this relationship was found for females, as acceptance communication predicted only one role ambiguity dimension (evaluation of role performance on defense). These findings have implications for applied practice in terms of reducing group members' perceptions of role ambiguity in interdependent team sport. 相似文献

The role of attention in the formation of auditory streams 总被引:1,自引:0,他引:1
There is controversy over whether stream segregation is an attention-dependent process. Part of the argument is related to the initial formation of auditory streams. It has been suggested that attention is needed only to form the streams, but not to maintain them once they have been segregated. The question of whether covert attention at the beginning of a to-be-ignored set of sounds will be enough to initiate the segregation process remains open. Here, we investigate this question by (1) using a methodology that does not require the participant to make an overt response to assess how the unattended sounds are organized and (2) structuring the test sound sequence to account for the covert attention explanation. The results of four experiments provide evidence to support the view that attention is not always required for the formation of auditory streams. 相似文献

Detection of a target grouping is expedited when the target display is preceded by presentation of an oscillating premask that includes priming elements presented intraphasically and below detection threshold at the display locations subsequently occupied by the target. Five experiments were performed to investigate how priming is affected by both the complexity and the geometry of prime/target forms. Experiment 1 showed that the subjective complexity of different polygons was coded in accord with an objective measure of form complexity. Experiments 2 and 3 revealed oscillatory priming to increase as a function of the subjective complexity of prime/target forms when those forms were regular and predictable. However, Experiments 4 and 5 showed that this relation did not hold when the prime/target forms were irregular and unpredictable. Taken together, it is argued that both subjective complexity and the Pr?gnanz quality of the prime/target forms come to determine the magnitude of priming. These results are discussed with reference to current physiological hypotheses regarding perceptual organization. 相似文献

Use of Functional Magnetic Resonance Imaging in the Early Identification of Alzheimer's Disease 总被引:2,自引:0,他引:2
A growing body of evidence suggests that a preclinical phase of Alzheimer's disease (AD) exists several years or more prior
to the overt manifestation of clinical symptoms and is characterized by subtle neuropsychological and brain changes. Identification
of individuals prior to the development of significant clinical symptoms is imperative in order to have the greatest treatment
impact by maintaining cognitive abilities and preserving quality of life. Functional magnetic resonance imaging (fMRI) offers
considerable promise as a non-invasive tool for detecting early functional brain changes in asymptomatic adults. In fact,
evidence to date indicates that functional brain decline precedes structural decline in preclinical samples. Therefore, fMRI
may offer the unique ability to capture the dynamic state of change in the degenerating brain. This review examines the clinical
utility of blood oxygen level dependent (BOLD) fMRI in those at risk for AD as well as in early AD. We provide an overview
of fMRI findings in at-risk groups by virtue of genetic susceptibility or mild cognitive decline followed by an appraisal
of the methodological issues concerning the diagnostic usefulness of fMRI in early AD. We conclude with a discussion of future
directions and propose that BOLD-fMRI in combination with cerebral blood flow or diffusion techniques will provide a more
complete accounting of the neurovascular changes that occur in preclinical AD and thus improve our ability to reliably detect
early brain changes prior to disease onset. 相似文献

The Violence Risk Scale-Sexual Offender version (VRS-SO) is a rating scale designed to assess risk and predict sexual recidivism, to measure and link treatment changes to sexual recidivism, and to inform the delivery of sexual offender treatment. The VRS-SO comprises 7 static and 17 dynamic items empirically or conceptually linked to sexual recidivism. Dynamic items with higher ratings identify treatment targets linked to sexual offending. A modified stages of change model assesses the offender's treatment readiness and change. File-based VRS-SO ratings were completed on 321 sex offenders followed up an average of 10 years post-release. VRS-SO scores predicted sexual and nonsexual violent recidivism post-release and demonstrated acceptable interrater reliability and concurrent validity. A factor analysis of the dynamic items generated 3 factors labeled Sexual Deviance, Criminality, and Treatment Responsivity, all of which predicted sexual recidivism and were differentially associated with different sex offender types. The dynamic items together made incremental contributions to sexual recidivism prediction after static risk was controlled for. Positive changes in the dynamic items, measured at pre- and posttreatment, were significantly related to reductions in sexual recidivism after risk and follow-up time were controlled for, suggesting that dynamic items are indeed dynamic or changeable in nature. 相似文献

Vitevitch and Luce (1998) showed that the probability with which phonemes co-occur in the language (phonotactic probability)
affects the speed with which words and nonwords are named. Words with high phonotactic probabilities between phonemes were
named more slowly than words with low probabilities, whereas with nonwords, just the opposite was found. To reproduce this
reversal in performance, a model would seem to require not merely sublexical representations, but sublexical representations
that are relatively independent of lexical representations. ARTphone (Grossberg, Boardman, & Cohen, 1997) is designed to meet
these requirements. In this study, we used a technique called parameter space partitioning to analyze ARTphone’s behavior
and to learn if it can mimic human behavior and, if so, to understand how. To perform best, differences in sublexical node
probabilities must be amplified relative to lexical node probabilities to offset the additional source of inhibition (from
top-down masking) that is found at the sublexical level. 相似文献

Genetic background differences and nonassociative effects in mouse trace fear conditioning 下载免费PDF全文
Fear conditioning, including variants such as delay and trace conditioning that depend on different neural systems, is widely used to behaviorally characterize genetically altered mice. We present data from three strains of mice, C57/BL6 (C57), 129/SvlmJ (129), and a hybrid strain of the two (F(1) hybrids), trained on various versions of a trace fear-conditioning protocol. The initial version was taken from the literature but included unpaired control groups to assess nonassociative effects on test performance. We observed high levels of nonassociative freezing in both contextual and cued test conditions. In particular, nonassociative freezing in unpaired control groups was equivalent to freezing shown by paired groups in the tests for trace conditioning. A number of pilot studies resulted in a new protocol that yielded strong context conditioning and low levels of nonassociative freezing in all mouse strains. During the trace-CS test in this protocol, freezing in unpaired controls remained low in all strains, and both the C57s and F(1) hybrids showed reliable associative trace fear conditioning. Trace conditioning, however, was not obtained in the 129 mice. Our findings indicate that caution is warranted in interpreting mouse fear-conditioning studies that lack control conditions to address nonassociative effects. They also reveal a final set of parameters that are important for minimizing such nonassociative effects and demonstrate strain differences across performance in mouse contextual and trace fear conditioning. 相似文献

Implicit, or nonconscious, self-esteem is often assumed to involve a unidimensional evaluation of the self. Our studies demonstrate that implicit self-esteem is in fact multifaceted and can be divided into at least two dimensions, which we term self-liking and self-attractiveness. Among participants for whom narcissistic thoughts and feelings were experimentally activated, we found that the two dimensions of implicit self-esteem were differentially associated with self-reported narcissism (Study 1) and feelings of aggressiveness (Study 2). In particular, narcissistic reactions were predicted by the combination of a high level of implicit self-attractiveness and a low level of implicit self-liking. These findings add to the growing understanding of the complexities of implicit self-esteem. 相似文献
