The purpose of the current study was to examine the effects of a multicomponent intervention that included discrimination training, real-time visual feedback, and self-monitoring on postural behavior at a computer workstation in a simulated office environment. Using a nonconcurrent multiple baseline design across 8 participants, the study assessed the effects of the intervention across three postural variables. Following an information phase, the intervention started for the lowest stable postural variable. The intervention led to substantial improvements in safety behavior for most targeted postural variables. A reversal to the information phase for 2 participants did not lead to decreases in safety. Postures self-monitored with high accuracy improved to a greater degree than postures self-monitored with low accuracy. 相似文献

The current study used a microworld simulation to investigate the direction of the relationship between group cohesiveness and performance. The study involved ten 4‐person teams who undertook 12 sessions of an air traffic control simulation. Performance and cohesiveness data were collected at each 1‐hr session. Using hierarchical linear modeling, group performance was found to predict group cohesiveness and not vice‐versa. These findings are discussed with respect to previous research and popular theories of group development. 相似文献

For clear and unambiguous social categories, person perception occurs quite accurately from minimal cues. This article addresses the perception of an ambiguous social category (male sexual orientation) from minimal cues. Across 5 studies, the authors examined individuals' actual and self-assessed accuracy when judging male sexual orientation from faces and facial features. Although participants were able to make accurate judgments from multiple facial features (i.e., hair, the eyes, and the mouth area), their perceived accuracy was calibrated with their actual accuracy only when making judgments based on hairstyle, a controllable feature. These findings provide evidence that suggests different processes for extracting social category information during perception: explicit judgments based on obvious cues (hairstyle) and intuitive judgments based on nonobvious cues (information from the eyes and mouth area). Differences in the accuracy of judgments based on targets' controllability and perceivers' awareness of cues provides insight into the processes underlying intuitive predictions and intuitive judgments. 相似文献

One of the most significant existential dilemmas for the religious person is the discrepancy between the assertion that God
is everywhere and eternally present, and the inability to become aware of His presence. In this paper, we discuss how developments
in our understanding of the brain’s mechanisms for perception may resolve this apparent contradiction. We submit that if God
is eternally present and unchangeable, then by the process of neuronal habituation, an individual can be “unaware” of the
presence of God. We also discuss the limits of human perception and illustrate the biblical questions concerning the awareness
of God. 相似文献

This study examined the predictive validity of two widely used measures of psychopathic traits, the Psychopathy Checklist--Revised (PCL-R; Hare, 2003) and the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996). Records of institutional infractions were obtained for a young adult sample of prison inmates (N = 46), who were followed for approximately two years following administration of these two scales. The PPI total and two factor scores predicted the total number of infractions committed (r ranging from .28 to .36). PPI Factor I showed some evidence of stronger associations with non-aggressive infractions (r = .36), whereas PPI Factor II was the strongest correlate of aggressive misconduct (r = .24). The total and facet scores of the PCL-R were not significantly predictive of any form of institutional misconduct, with effect sizes ranging from negligible to small (median r = .14, r ranging from -.01 to .21). 相似文献

Few instruments are available to assess compulsive hoarding and severity of clutter. Accuracy of assessment is important to
understanding the clinical significance of the problem. To overcome problems associated with over- and under-reporting of
hoarding symptoms, the clutter image rating (CIR) was developed. This pictorial scale contains nine equidistant photographs
of severity of clutter representing each of three main rooms of most people’s homes: living room, kitchen, and bedroom. The
psychometric properties of this measure were examined in two studies. Internal consistency, test–retest, and interobserver
reliabilities were good and convergent validity with other questionnaire and interview measures was also good. The CIR correlated
more strongly with measures of clutter than with other hoarding and psychopathology scales. The CIR’s very brief pictorial
assessment method makes it useful in clinical and treatment contexts for measuring the clutter dimension of compulsive hoarding.
The Clutter Image Rating (CIR) is available in conjunction with the following publication: Steketee, G., & Frost, R.O. (2007).

Gambling is relatively common among university students, but few studies examine factors that contribute to gambling behavior
in this cohort. Based on evidence that cognitive distortions may play a role in gambling behavior, this study examined the
factor structure of gambling-related cognitive distortions using the Gambler’s Beliefs Questionnaire (GBQ; Steenbergh et al.,
Psychology of Addictive Behaviors, 16:143–149, 2002) in a sample of 393 college undergraduates. Confirmatory factor analysis was used to test a previously
reported two-factor model, comprising dimensions of Illusion of Control (IOC) and Luck/Perseverance (L/P). An oblique, but
not orthogonal, two-factor model was confirmed but did not provide an incrementally better fit to the data than a one-factor
model. However, multiple regression analyses showed that the L/P scale accounted for significant variance in the criterion
when controlling for IOC items. This suggests that IOC items provide redundant information and that gambling-related cognitive
distortions in this sample can be adequately assessed using solely the L/P factor.

Laboratory analogues of classroom activities on which children with low working memory skills have been observed to perform very poorly were developed and employed in two studies. In Study 1, 5‐ and 6‐year‐old completed one task involving recalling spoken sentences and counting the numbers of words, and another task involving the identification of rhyming words in spoken poems. Poorer performance of low than average working memory children was obtained on the recall measure of both tasks. In Study 2, 5‐ and 6‐year‐old children heard spoken instructions involving the manipulation of a sequence of objects, and were asked either to perform the instructions or repeat them, in different conditions. The accuracy of performing but not repeating instructions was strongly associated with working memory skills. These results indicate that working memory plays a significant role in typical classroom activities that involve both the storage and mental manipulation of information.
