It was hypothesized that individual and situational variables, as a whole, will show stronger relationships with work-related attitudes than with mental health indices. Work-related attitudes, on the other hand, were expected to contribute more strongly to mental health than the individual and situational variables. Results obtained from two groups of staff professionals and retail store managers, using primarily questionnaire data, supported these hypotheses. Career and work satisfaction emerged as the strongest contributors to mental health. Situational variables such as job characteristics, supervisory style, and pay related more strongly to the attitudinal variables than to mental health. This pattern suggests that career and work satisfaction may serve as intervening variables in the relationship between situational variables and mental health. 相似文献

The importance of individual response patterns in the treatment of phobic patients was examined in the present study. Forty psychiatric outpatients with social phobia were assessed with a social interaction test which was videotaped. Heart rate was continuously monitored during the test. On the basis of their reactions in the test situation, the patients were divided into two groups showing different response patterns; behavioral and physiological reactors. Within each group half of the patients were randomly assigned to a behaviorally focused method (social skills training) while the other half received a physiologically focused method (applied relaxation). The patients were treated individually in 10 sessions. The within-group comparisons showed that both treatments yielded significant improvements on most measures. The between-group comparisons showed that for the behavioral reactors, social skills training was significantly better than applied relaxation on six out of ten measures, and for the physiological reactors applied relaxation was significantly better than social skills training on three of the measures. The results support the hypothesis that greater effects are achieved when the method used fits the patient's response pattern. 相似文献

Investigations using in vivo magnetic resonance (MR) morphometry have shown that left-right asymmetry of the planum temporale (PT) is a structural correlate of hemispheric functional asymmetries in adult humans (e.g., handedness, language representation). Postmortem studies of brains of fetuses and newborns have demonstrated that PT asymmetry becomes visible as early as in the last gestational trimester. The same studies could not clarify when the full (adult) degree of PT asymmetry is reached during brain development and whether this process may be influenced by functional specialization during childhood. We examined 61 neuropsychiatrically normal right-handed children aged 3 to 14 years (mean age +/-SD, 8.4 +/- 2. 7 years; cross-sectional study). MR morphometry showed no change in PT or planum parietale asymmetry with increasing age or brain volume. An unexpected gender difference of unknown significance emerged, with girls displaying a stronger leftward PT asymmetry, independently of age. For the age range studied, the results suggest that functional differentiation follows a structural asymmetry that is already "preset." Copyright 1999 Academic Press. 相似文献

In four experiments, we tested whether haptic comparison of curvature ranging from ?41m to +41m is qualitatively the same for static and for dynamic touch. In Experiments 1 and 3, we tested whether static and dynamic curvature discrimination are based on height differences, attitude (slope) differences, curvature differences, or a combination of these geometrical variables. It was found that both static and dynamic haptic curvature discrimination are based on attitude differences. In Experiments 2 and 4, we tested whether this mechanism leads to errors in the comparison of stimuli with different lengths for static and dynamic touch, respectively. If the judgments are based on attitude differences, subjects will make systematic errors in these comparisons. In both experiments, we found that subjects compared the curvatures of strips of the same length veridically, whereas they made systematic errors if they were required to compare the curvatures of strips of different lengths. Longer stimuli were judged to be more curved than shorter stimuli with the same curvature. We conclude that similar mechanisms underlie static and dynamic haptic curvature comparison. Moreover, additional data comparison showed that static and dynamic curvature comparison is not only qualitatively, but also quantitatively similar. 相似文献

The literature on psychological stress among women consistently points to the adverse effects of child rearing on mothers, particularly those caring for children with physical or mental handicaps. Early studies of the effects on family functioning of caring for a child with severe learning difficulties adopted a pathological approach in which it was assumed that psychological distress was inevitable among family members, particularly mothers. Recent research has emphasised that many families cope with and adapt to the stress they experience, and seeks to discover how they do so. The paper reports on a study of 166 mothers caring for a child with severe learning difficulties. The aim of the study was to investigate both the factors associated with maternal stress and those which might mediate or buffer the effects of stress. The study used the Folkman and Lazarus' (1979) transactional model of stress. Stress is the condition that results when person/environment transactions lead the individual to perceive a discrepancy between the demands of a situation and his/her resources or ability to cope with those demands. The nature and type of coping generated by a person will be determined by the coping resources in the person's environment. The model identifies five categories of coping resource: utilitarian resources, health/morale, social networks, general and specific beliefs, and problem solving skills. In our study, the five coping resources were represented by the mother's social class and appraisal of her financial worries, physical health, social support, acceptance of and adjustment to the child, and assessment of coping skills. Stress was measured by the Malaise Inventory (Rutter, 1970). Four of the five coping resources were found to be significant contributors in a hierarchical regression analysis of stress scores, contributing additional variance beyond that of behavioural and other child characteristics. Altogether, 55% of the variance in stress scores was explained. 相似文献

This study examines the construct validity of the revised version of the Strelau Temperament Inventory (STI-R) and the short scale (STI-RS), which were introduced by Strelau, Angleitner, Bantelmann and Ruch (1990). Hypotheses about the relationship between the content scales of the STI-R, viz. Strength of Excitation (SE), Strength of Inhibition (SI), and Mobility (MO) of CNS properties, and (a) other personality/temperament dimensions referring to the level of arousal, (b) selected temperament inventories, and (c) selected personality scales are derived and tested in a total of four samples with altogether 420 Ss. The inventories investigated include, among others, the Eysenck Personality Questionnaire—Revised (EPQ-R), Zuckerman's Sensation Seeking Scale (SSS), the I.7 Impulsiveness Questionnaire (I.7), the Affect-Intensity-Measure (AIM), the EASI, the Structure of Temperament Questionnaire (STQ), and the Revised Dimensions of Temperament Survey (DOTS-R). In general, the hypotheses regarding the place of the STI-R in the temperament and personality domain were confirmed. A factor analysis of the STI-R, EASI, and DOTS-R yielded five factors: Emotional Stability, Rhythmicity, Activity/Tempo, Sociability, and Impulsivity versus Impulse Control. 相似文献

The aim of this paper is to examine the use of psychophysiological and/or psychophysical measures employed as (a) tools aimed at diagnosing personality/temperament traits and (b) criteria for estimating the construct validity of personality/temperament inventories. The exploration is based on three diferent sources: (1) data collected mainly within the neo-Pavlovian approach on CNS properties; (2) selected examples of studies in the domain of sensation-seeking, neuroticism, and extraversion; and (3) theoretical considerations regarding the specificity of phenomena being measured by means of psychometric and psychophysiological/psychophysical scores. It is concluded that psychophysiological and psychophysical measures may be used for the assessment of personality/temperament traits or for estimating the construct validity of psychometric tools applied in personality (temperament) research under very strict requirements and limited circumstances only. In most of the studies conducted up to now, these circumstances and requirements have not been fulfilled. 相似文献

Thresholds for vibrotactile discrimination of pulse interval were determined for pulse frequencies between 1 and 384 Hz. The results point to a temporal resolution significantly more accurate than that demonstrated in earlier studies. Although touch as a vibratory sensor is in general much inferior to audition, the present results show a striking resemblance to those obtained on auditory pitch. The neurophysiological implications for the tactile as well as for the auditory system are discussed. 相似文献
