The authors report the collaborative efforts of 2 research teams that independently investigated the effects of stable personality traits (the Big Five) and specific behavioral competencies (cultural flexibility, task and people orientations, and ethnocentrism) on key dimensions of expatriate effectiveness: psychological adjustment, assignment withdrawal cognitions, and job performance. Analyses of multiple-source and longitudinal data from 3 studies, including a diverse sample of expatriates in Hong Kong and separate samples of Korean and Japanese expatriates posted around the world, indicate several direct effects of individual differences. Further data show reliable distinctions between the traits and competencies as well as incremental prediction by either set of predictors in the presence of the others.  相似文献

This paper describes the development of COMPsych, a computerized system to disseminate information about software dealing with ail aspects of psychology. The need for such a service, the various components, and the general operation of the system are described. The system will contain a catalog of commercial and public domain software, a library of freeware, a directory of computer users, and a bulletin board.  相似文献

Narratives are not only about events, but also about the emotions those events elicit. Understanding a narrative involves not just the affective valence of implied emotional states, but the formation of an explicit mental representation of those states. In turn, this representation provides a mechanism that particularizes emotion and modulates its display, which then allows emotional expression to be modified according to particular contexts. This includes understanding that a character may feel an emotion but inhibit its display or even express a deceptive emotion. We studied how 59 school-aged children with head injury and 87 normally-developing age-matched controls understand real and deceptive emotions in brief narratives. Children with head injury showed less sensitivity than controls to how emotions are expressed in narratives. While they understood the real emotions in the text, and could recall what provoked the emotion and the reason for concealing it, they were less able than controls to identify deceptive emotions. Within the head injury group, factors such as an earlier age at head injury and frontal lobe contusions were associated with poor understanding of deceptive emotions. The results are discussed in terms of the distinction between emotions as felt and emotions as a cognitive framework for understanding other people's actions and mental states. We conclude that children with head injury understand emotional communication, the spontaneous externalization of real affect, but not emotive communication, the conscious, strategic modification of affective signals to influence others through deceptive facial expressions.  相似文献

Text comprehension processes were investigated in children with hydrocephalus, a neurodevelopmental disorder associated with good word decoding, but deficient reading comprehension. In Experiment 1, hydrocephalus and control groups were similar in processes related to activating word meanings and using context to enhance meaning. The hydrocephalus group was poorer at suppressing contextually irrelevant meanings. In Experiment 2, the hydrocephalus group had difficulty integrating information from an earlier read sentence to understand a new sentence as textual distance between the two propositions increased, suggesting difficulty in reactivation processes related to comprehension. Results are discussed in relation to cognitive and neurocognitive models of comprehension.  相似文献

In two experiments, we investigated the role of perceptual information in spurious recognition judgments. Participants viewed lists of words in various unusual fonts. The frequency with which each font was presented was manipulated at study: Each font was presented with 1 or 12 different words in Experiment 1 and with 1 or 20 words in Experiment 2. Although the participants were instructed in a word recognition test to judge only on the basis of the word, regardless of font, there were significantly more false alarms for new words seen in a previously presented font than for new words presented in a novel (not seen at study) font in Experiment 1. In Experiment 2, the participants were significantly more likely to make a false alarm to a new word seen in a font that had been used to present 20 words during study than to a font that had been used to present only 1 word during study. The data show a mirror effect, in which words tested in low-frequency fonts produced more hits and fewer false alarms than did words tested in high-frequency fonts. These results show that irrelevant perceptual information plays a role in recognition judgments by providing spurious sources of familiarity and, thus, provide evidence that perceptual information is represented and processed in the same way as semantic information.  相似文献

Bilateral facilitation of motor control in chronic hemiplegia   总被引:3,自引:0,他引:3  
The present study addressed the efficacy of concurrently moving both arms, with and without a load added to the uninvolved arm, in facilitating the quality of movement of the involved side in individuals with moderate, chronic hemiplegia. Six hemiplegic cerebrovascular accident (CVA) subjects with left-hemisphere lesions participated in the study. The four males and two females ranged from 46 to 77 years of age and 30–96 months post-CVA. All subjects scored at least 70% on the Fugl-Meyer test of motor function. The task was to perform discrete unilateral and bilateral elbow extensions in the horizontal plane. The movements were 45° in amplitude and were to terminate in a 10° target zone that was indicated by an illustration of a coffee mug. The instructions were to move toward the mug as smoothly as possible in a movement time (MT) determined to be 20% longer than their minimal MT for that distance. The primary dependent variable was the percentage of continuous vs. discontinuous trajectories observed in each condition, based on whether or not a transient hesitation or reversal was observed. Phase of peak velocity was also quantified as a general indication of the symmetry of the velocity profile. Three of the six subjects exhibited a greater percentage of continuous movements of the involved arm in the nonloaded bilateral condition than the unimanual condition. Five subjects benefited when the uninvolved arm was inertially loaded in the bilateral condition when compared with unimanual performance. Only the oldest subject failed to exhibit facilitation. Peak velocity phase tended to normalize toward symmetry in the bilateral conditions. These findings are consistent with prior evidence that the control of the involved arm improves during bimanual performance for some hemiplegic subjects. It further suggests loading the uninvolved arm may benefit some subjects with respect to unimanual performance, with age perhaps playing a role in determining efficacy.  相似文献

To test the differential validity of the posttraumatic stress disorder (PTSD) classification, 3 groups of youths (PTSD, traumatized PTSD negatives, and controls) were examined. Youth with major comorbid disorders were excluded. On the basis of an analysis of parent-derived Child Behavior Checklist (CBCL) ratings, significant variations in CBCL scores were associated with PTSD but not with exposure to exceptional stress in the absence of PTSD. The results also indicated that traumatic exposure without the development of PTSD was not associated with higher estimates of psychopathology.  相似文献

What are the best quantitative methods for studying cognitive decline? This question was investigated in a sample of 638 individuals aged 50 years and older from the Swedish Adoption/Twin Study of Aging. A battery of cognitive tests tapping multiple domains was administered to each individual from 2 to 7 times over a span of 10 years. Four methods of operationalizing cognitive decline were compared: change scores, a criterion-based method, least squares, and random effects regression (RER). The RER results were most consistent with a significant decline across measures and differences between demented and nondemented individuals. Predicted slopes from the RER model also showed the strongest interrelationships within and across cognitive domains as indicated by factor analysis results and stronger associations with demographic, health, and psychosocial predictors.  相似文献
