Average evoked brain responses (EBR) to the onset (ON) and cessation (OFF) of 1-kHz pure-tone stimuli were computed from human scalp recordings. Stimuli of 2,000 msec duration were presented binaurally at 10 intensity levels. The waveform of the OFF EBR is similar to the ON EBR. The ON response is in general larger than the OFF response. Comparable ON and OFF amplitude response measures are both sensitive to changes in stimulus intensity which may be fit by a linear function. Significant differences in slope between ON and OFF amplitude intensity functions were demonstrated, which suggests different physiological systems for these responses. 相似文献

Two studies examined the models of female achievement available to television viewers. The studies surveyed television's portrayal of both achievement behavior and its social consequences for the female achiever. Study I compared female models at four levels of achievement. Only those models at the lowest level of achievement were depicted as having successful social relations with males. Study II compared the marital status of male and female job holders. Compared with male job holders, females were depicted as less likely to be married, less likely to be successfully married, and more likely to be unsuccessfully married. Data on married females showed that those who held jobs were depicted as having 10 times as many unsuccessful marriages (proportionately) as housewives. It is suggested that female achievers portrayed on television are depicted in a way that does not encourage female viewers to imitate their behavior and in fact serves to inhibit achievement-oriented behavior in female viewers. 相似文献

The parents of 41 children who had been given an individually-administered intelligence test were contacted approximately 19 months after testing. The sample included 20 parents who had learned their child had an Average IQ (children'smeanIQ = 100.8) and 21 parents who had learned their child had an Above Average IQ (children'smeanIQ = 130.0). Parents of Average IQ children were less accurate in their memory of test results, and they and their children experienced fewer positive consequences from IQ testing than Above Average children and their parents. Children with Above Average IQ experienced extremely low frequencies of sibling rivalry, conceit or pressure, and they and their parents experienced increased pride and/or self-confidence as a result of the IQ testing. The results as a whole suggest that parents of Average IQ children may need more psychological support during the parent informing process than parents of Above Average IQ children. 相似文献

This paper proposes a model of employee turnover based upon the existing literature from psychological, sociological, and economic perspectives. Voluntary turnover is posited to have three major classes of determinants: characteristics of the individual employee, work-related factors, and the states of certain economic variables. The model proposes that economic factors serve to control the degree to which individual and work-related factors can explain variation in turnover. It is hypothesized that individual and work-related variables will be more predictive of turnover under prosperous economic conditions than when the economy is strained. The model also proposes four classes of consequences of turnover: individual, organizational-social, organizational-economic, and societal. Recommendations for future turnover research are discussed. 相似文献

The rating scale responses of three groups of men and women to thermal and painful radiant heat stimuli were studied over a 4-week period. Receiver operating characteristic curve parameters were computed for each of the phases of the menstrual cycle. Women with normal menstrual periods experienced a heightened sensitivity to pain during ovulation. This effect was absent in women using oral contraceptive pills and in men. The findings demonstrate that past reports of pain threshold changes in association with menstrual phase were basically sensory effects and not just a result of shifts in the observer’s criteria for reporting pain. In addition, sex differences in pain perception were found only when men were compared with women who were ovulating. 相似文献

Retrospective questionnaires show cyclical variations in moods and behaviors across the menstrual cycle. However, results obtained from daily mood questionnaires are inconsistent. In the present study, which ran for 11 weeks, self-report measures of menstrual symptomatology, using the 8-factor Moos (1968, 1969 a,c) Menstrual Distress Questionnaire (MDQ), were investigated. The MDQ was administered under conditions that made the menstrual cycle a salient (retrospective questionnaire) or not a salient (daily questionnaire) part of the study. The study included women who were taking and not taking oral contraceptives. A 2×3 analysis of variance (with the two groups of women and three menstrual cycle phases as independent variables) yielded broad cyclical variations only in the menstrual cycle salient condition. When the menstrual cycle was not a salient part of the study, only the pain factor reached significant cyclical variation (p<.01).A 2×3 analysis of variance (with the two types of questionnaires and three menstrual cycle phases as independent variables) indicated that for women not taking oral contraceptives the two questionnaires differed on pain (p<.01), concentration (p<.01), autonomic reaction (p<.05), and water retention (p<.01). Phase effects were significant on all factors, with largest cyclical variations in the menstrual cycle salient condition. A similar analysis for women taking oral contraceptives yielded fewer significant differences. These results suggest that questionnaires that make the menstrual cycle a salient part of the study may exaggerate possible cyclical variations in moods and behaviors.The authors are grateful to Dawn Christie Burns and Ross Hodges for their help in data reduction. 相似文献

This study examined whether a relationship exists between maternal employment and self-esteem of offspring. A questionnaire incorporating the Adjective Generation Technique (AGT) was administered to undergraduate psychology students from intact two-parent families. Subjects were divided into four categories: males whose mothers worked during their childhood (n=33), males whose mothers remained home (n=49), females whose mothers worked (n=54), and females whose mothers remained home (n=49). Data were analyzed using a 2 × 2 analysis of variance. Results indicated no differences in self-esteem for subjects of either sex in conjunction with the employment of their mothers. Instead, the subject's sex was the critical component affecting self-esteem. Males reported themselves significantly more favorably than did females. 相似文献

Previous investigations of the social behavior of handicapped preschool children (Journal of Applied Behavior Analysis, 1974, 7 , 583–590; Journal of Applied Behavior Analysis, 1976, 9 , 31–40; Journal of Applied Behavior Analysis, 1977, 10 , 289–298) demonstrated that introduction of adult or peer confederate intervention agents produced substantial increases in levels of positive social behavior emitted by the subjects. In addition, it was observed that changes in rates of positive social behavior emitted by recipients of intervention tactics were accompanied by parallel changes in rates of positive social behavior emitted by interacting peers. However, with one limited exception, sudden removals of arranged intervention procedures were followed by immediate reductions in the levels of positive social behavior emitted by subjects and peers in each study. The current investigation was designed to examine the effects of response-dependent removal of intervention procedures on the positive behavior of three socially withdrawn preschool boys. Interactive effects on the social behavior of classroom peers who did not receive adult prompts and contingent attention events were also examined. A combination of withdrawal of treatment and multiple baseline procedures was employed. The three target subjects received fixed numbers of prompts and contingent attention events during Intervention I and Intervention II, Phase 1 conditions. During Intervention II, Phase 2 conditions, prompts and contingent attention events were reduced on a response-dependent basis for two subjects and on a response-independent basis for the third subject. The results suggest that: (a) the intervention procedures produced marked increases in positive social behavior emitted by each subject; (b) response-dependent fading and thinning, contrasted with response-independent tactics, maintained levels of positive social behavior equivalent to those observed during Intervention I and Intervention II, Phase 1 conditions; (c) changes in positive and negative behaviors emitted by peers paralleled changes in positive and negative behaviors emitted by each subject; and (d) no “spillover” of treatment effects was noted for subjects during periods in which they were not direct recipients of intervention procedures. 相似文献

This study investigated the recommendations for special services made by 76 teachers and 53 psychologists for children characterized through 106 case studies with reference to 16 variables. The results indicated that both groups consider IQ, test achievement, class achievement, and home-related anxiety important in making recommendations, with IQ and test achievement weighted more heavily by psychologists than by teachers. SES is important only to psychologists, while adaptive behavior and self-concept are important only to teachers. Recommendations by both groups were not influenced by children's ethnicity, language, home values, school-related anxiety, classroom manageability, and interpersonal relationships. 相似文献
