Several factors are critical in designing effective simulator systems for driving research and driver assessment. First, there is cost, in terms of which, less is better. Costly systems are sometimes fine for specific research purposes, but they are impractical for most other purposes. Second, there is realism; in this case, more may be better, but we don’t know how much realism is really necessary for good prediction of actual driving behaviors. Recent evidence suggests that real-world clutter may enhance prediction, but it also makes interpreting research more difficult. More realism may increase cost, but this is not necessarily the case. Third, there is user-friendliness, in terms of which, again, more is better. Systems that are easier to operate require less-highly trained personnel; hence, increasing user-friendliness also decreases cost, especially for assessment. We demonstrated a highly user-friendly, low-cost, moderately realistic, and partly interactive computer-video driving research and assessment system. In recent research, we obtained multipleR values ofA7 for older drivers with only three to four scenarios predicting a real-world crash index. 相似文献

Personality and Coping: Three Generations of Research 总被引:1,自引:0,他引:1
ABSTRACT This article introduces the Journal of Personality 's special issue on coping and personality. It first presents a historical overview of the psychological study of how people cope with stress and identifies three generations of theory and research: (a) the psychoanalysts and the ego development school, which tended to equate personality and coping strategies; (b) the transactional approach, which appeared in the 1960s and emphasized situational and cognitive influences on coping while downplaying the role of individual differences; and (c) the most recent, "third generation," whose work is represented in this special issue and focuses on the role of personality in coping while maintaining strong operational distinctions among coping, personality, appraisal, and adaptational outcomes. This introduction concludes with a discussion of unresolved conceptual and methodological issues and a brief orientation to the third-generation articles that follow in this special issue. 相似文献

In this paper, it is proposed that a) psychosocial medicine is best taught in a setting that provides technical and emotional support, while seizing for teaching only those moments when the learner is most receptive; and b) that the setting should avoid the development of a separate psychosocial skills curriculum, but should take the student where he or she is and integrate the psychosocial skills into his or her everyday biomedical practice. The paper gives specific case examples in which family based psychosocial issues were preeminent in the clinical problem-solving medical residents faced. 相似文献

No one factor could have as great an impact on multinational corporations (MNCs) than the dual-career phenomena. The selection of expatriate candidates is a complex process made more arduous by the career orientation of the expatriate's spouse. The need for a social support network is essential for the dual-career family to increase the probability of successfully completing an expatriate assignment. 相似文献

Holland's theory of congruence of work environments was examined by analyzing the career redirection of 62 men of managerial and professional level who changed occupations between the ages of 33 and 54. Three-letter personality codes for each subject were obtained by administering the Strong-Campbell Interest Inventory. Dictionary of Occupational Titles codes for first and second occupation were obtained and then translated into Holland codes. These were compared to the personality code for each man to determine whether the first or second job was more congruent. It was found that 26 men changed to careers more congruent with their personality, 25 to careers less congruent, and 11 made no change. The results of the study do not lend support to Holland's theory, probably because of the imprecision of DOT categories for research purposes. The need for a more reliable means for coding work environments is discussed. 相似文献

The question of whether or not lexical information is accessed directly from a visual code or by a process of phonetic mediation was investigated in three lexical decision experiments. Phonetic similarity influenced decisions about visually presented words only when they were to be discriminated from orthographically regular nonwords. When consonant strings or random letter strings were used as nonwords, phonetic similarity effects were absent, and graphemic similarity exerted a powerful effect while evidence of semantic priming was found. This pattern was interpreted as evidence of direct lexical access, which is probably the normal processing mode for skilled readers. Phonetic coding, when it occurs, may be a storage strategy rather than a part of the addressing chain for lexical structures. 相似文献

The relationship between the Fourier spectra of visual textures (represented by four hypothetical visual channels sensitive to spatial frequencies) and the perceptual appearance of the textures was investigated. Thirty textures were synthesized by combining various spatial frequencies of different amplitudes. Twenty subjects grouped the textures into 2, 3, 4, and 5 groups based on the similarity of their appearance. The groupings were analyzed by means of linear discriminant analysis using the activity of the four channels as predictor variables. The groupings were also examined by multidimensional scaling, and the resulting stimulus configuration was canonically correlated with the channel activity. The results of both analyses indicate a strong relationship between the perceptual appearance of the textures and their Fourier spectra. These findings suport a multiple-channel spatial-frequency model of perception. 相似文献

Summary Dichotic sequence discrimination was studied by means of a three-alternative forced-choice method. Two of the alternatives (same) consisted of a single pair of dichotic clicks with the stimulus at one ear preceding the stimulus at the other ear by a given temporal separation (e.g., R-t-L). One of the alternatives consisted of a single pair of clicks with the opposite sequence (e.g., L-t-R). The subjects' task was to discriminate between the different and the same dichotic pairs. The results indicate that discrimination is a nonmonotonic function of t, i.e., V- or U-shaped, with high levels at both short and long temporal separations (t=2 and 4 ms and t=64 and 96 ms) and with lower levels of discrimination for intermediate ts. A second experiment was performed to study the effect of continued practice by subjects trained in dichotic sequence discrimination for ts 4 and 64 ms (high discrimination levels) and for t=16 ms (low discrimination level). There was no systematic trend towards improvement over 8 blocks of 50 trials for each t. Discrimination levels of these ts did not differ between Experiments 1 and 2.Dr. Babkoff is spending the 1979–1981 academic year at the Walter Reed Army Institute of Research, Department of Military Medical Psychophysiology, Forest Glen Annex, Building 189, Washington, D.C. 20012, USAThe experiments were conducted at the Bar-Ilan University, Ramat-Gan, Israel.

The purpose of this study was to examine the validity of teachers' identification of problem children. Ninety-five third-grade children served as subjects. Teachers nominated children as a conduct problem, withdrawal problem, or normal, resulting in 16, 14, and 65 children being assigned to the three groups. Behavioral observations, peer sociometric ratings, and academic achievement scores were collected. The results indicated that conduct problem children differed from normal children on behavioral, sociometric, and academic measures, whereas withdrawn children differed from normals on the latter two measures. Conduct problem and withdrawal problem children did not differ on any of the dependent measures. The results suggest that teachers can identify children who are having difficulties in class but may be less accurate in differentiating between different types of problem children.This research was supported in part by NIMH grant MH-28859-01. Data reported in this article are part of a larger project assessing the social skills of children. 相似文献

This study explored the impact of paralinguistic phenomena on interpersonal attraction and physiological measures during dyadic interaction. Conversations between undergraduate subjects and same-sex experimenters were either synchronous or asynchronous, with half the asynchronous conversations including imposed long latencies and the remainder frequent interruptions. Results showed that imposed latencies were associated with decreased positive attributions and greater physiological arousal, but interruptions had a moderately positive effect. The findings were discussed in terms of Chapple's theory of interaction, and their implications for psychotherapy and other interviews. 相似文献
