Five-factor model of personality and job satisfaction: a meta-analysis 总被引:16,自引:0,他引:16
This study reports results of a meta-analysis linking traits from the 5-factor model of personality to overall job satisfaction. Using the model as an organizing framework, 334 correlations from 163 independent samples were classified according to the model. The estimated true score correlations with job satisfaction were -.29 for Neuroticism, .25 for Extraversion, .02 for Openness to Experience, .17 for Agreeableness, and .26 for Conscientiousness. Results further indicated that only the relations of Neuroticism and Extraversion with job satisfaction generalized across studies. As a set, the Big Five traits had a multiple correlation of .41 with job satisfaction, indicating support for the validity of the dispositional source of job satisfaction when traits are organized according to the 5-factor model. 相似文献

This study documents how the use of A. I. Huffcutt & W. A. Arthur's (1995) sample adjusted meta-analytic deviancy (SAMD) statistic for identifying outliers in correlational meta-analyses results in inaccuracies in mean r. Monte Carlo simulations found that use of the SAMD resulted in the overidentification of small relative to large correlations as outliers. Furthermore, this tendency to overidentify small correlations was found to increase as the magnitude of the population correlation increased and resulted in mean rs that overestimated the population correlation. The implications for meta-analysts are discussed, and 2 possible solutions are offered. 相似文献

The author examined the reliability and validity of the Chinese Family Awareness Scale (C-FAS) in 2 studies. In Study 1, data from 361 adolescents (a) showed that the C-FAS was temporally stable and internally consistent and (b) supported the concurrent and construct validities of the scale. In Study 2, data from clinical (N = 281) and nonclinical (N = 451) groups of adolescents showed that the C-FAS scores discriminated between the 2 groups. C-FAS scores were also correlated significantly with other measures of family functioning and psychological well-being. Results of the 2 studies suggest that the C-FAS displayed generally good psychometric properties in different samples of Chinese adolescents. 相似文献

Competition for attention between 2 written words was investigated by presenting the words briefly in a single stream of distractors (Experiment 1) or in different streams (Experiment 2-6), using rapid serial visual presentation at 53 ms/item. Stimulus onset asynchrony (SOA) was varied from 0 to 213 ms. At all SOAs there was strong competition, but which word was more likely to be reported shifted markedly with SOA. At SOAs in the range of 13-53 ms the second word was more likely to be reported, but at 213 ms, the advantage switched to the first word, as in the attentional blink. A 2-stage competition model of attention is proposed in which attention to a detected target is labile in Stage 1. Stage 1 ends when one target is identified, initiating a serial Stage 2 process of consolidation of that target. 相似文献

Effect of speech task on intelligibility in dysarthria: a case study of Parkinson's disease 总被引:2,自引:0,他引:2
This study assessed intelligibility in a dysarthric patient with Parkinson's disease (PD) across five speech production tasks: spontaneous speech, repetition, reading, repeated singing, and spontaneous singing, using the same phrases for all but spontaneous singing. The results show that this speaker was significantly less intelligible when speaking spontaneously than in the other tasks. Acoustic analysis suggested that relative intensity and word duration were not independently linked to intelligibility, but dysfluencies (from perceptual analysis) and articulatory/resonance patterns (from acoustic records) were related to intelligibility in predictable ways. These data indicate that speech production task may be an important variable to consider during the evaluation of dysarthria. As speech production efficiency was found to vary with task in a patient with Parkinson's disease, these results can be related to recent models of basal ganglia function in motor performance. 相似文献

Synesthetic color experiences influence memory 总被引:2,自引:0,他引:2
We describe the extraordinary memory of C, a 21–year–old student who experiences synesthetic colors (i.e., photisms) when she sees, hears, or thinks of digits. Using three matrices of 50 digits, we tested C and 7 nonsynesthetes to evaluate whether C's synesthetic photisms influence her memory for digits. One matrix consisted of black digits, whereas the other two matrices consisted of digits that were either incongruent or congruent with the colors of C's photisms. C's recall of the incongruently colored digits was considerably poorer than her recall of either the black or the congruently colored digits. The 7 nonsynesthetes did not show such differences in their recall of the matrices. In addition, when immediate recall of the black digits was compared with delayed recall of those digits (48 hr), C showed no decrease in performance, whereas each of the nonsynesthetes showed a significant decrease. These findings both demonstrate C's extraordinary memory and show that her synesthetic photisms can influence her memory for digits. 相似文献

How well do brief screening measures correspond with a full-scale assessment of psychopathy among juvenile offenders? This study compared 3 independent screening measures (the Antisocial Process Screening Device [APSD] Self-Report [A. A. Caputo, P. J. Frick, & S. L. Brodsky, 1999], the APSD Staff Rating [P. J. Frick & R. D. Hare, 2001], and the Psychopathy Content Scale [D. C. Murrie & D. G. Cornell, 2000] on the Millon Adolescent Clinical Inventory [T. Millon, 1993]) with the Psychopathy Checklist: Youth Version (PCL:YV; A. E. Forth, D. S. Kosson, & R. D. Hare, in press) in a sample of 117 incarcerated male juveniles. Modest correlations (.30-.49) were found between PCL:YV scores and those of the 3 screening measures, and there was moderate accuracy (67%-82%) in identifying youth who scored relatively high (> or = 25) on the PCL:YV. Although these results support the construct of adolescent psychopathy, they indicate substantial limitations in the use of psychopathy screening measures with juvenile offenders. 相似文献

The ALCOVE model of category learning, despite its considerable success in accounting for human performance across a wide
range of empirical tasks, is limited by its reliance on spatial stimulus representations. Some stimulus domains are better
suited to featural representation, characterizing stimuli in terms of the presence or absence of discrete features, rather
than as points in a multidimensional space. We report on empirical data measuring human categorization performance across
a featural stimulus domain and show that ALCOVE is unable to capture fundamental qualitative aspects of this performance.
In response, a featural version of the ALCOVE model is developed, replacing the spatial stimulus representations that are
usually generated by multidimensional scaling with featural representations generated by additive clustering. We demonstrate
that this featural version of ALCOVE is able to capture human performance where the spatial model failed, explaining the difference
in terms of the contrasting representational assumptions made by the two approaches. Finally, we discuss ways in which the
ALCOVE categorization model might be extended further to use “hybrid” representational structures combining spatial and featural
components. 相似文献

Historically, drugs that increase central cholinergic transmission have primarily been investigated for relieving cognitive symptoms in mild-to-moderate Alzheimer's disease. These efforts have led to the somewhat unexpected findings that cholinergic therapy has a beneficial effect on selected neuropsychiatric symptoms in AD across disease stages. In Parkinson's disease with dementia and dementia with Lewy bodies, cholinergic deficits are more severe than in AD, and there is emerging evidence that cholinesterase inhibitors are efficacious in treating core symptoms of attentional disturbance and psychosis. Recent data also suggest a rational basis for cholinergic therapy in vascular dementia. The cognitive and neuropsychiatric effects of cholinergic therapy observed in AD and other dementias form the crux of an integrative model of cholinergic therapeutic efficacy that encompasses the diverse central nervous system actions of acetylcholine and its complementary interactions with central monoamine transmitters. This heuristic framework highlights the broader therapeutic potential of cholinergic therapy for symptom-based indications in other neuropsychiatric disorders. 相似文献
