The stability of resting metabolic rate and diet-induced thermogenesis was assessed in a group of 8- to 12-year-old children over two sessions. Children were first oriented to the laboratory and participated in a practice session to adapt them to the laboratory procedures. The two metabolic sessions began with the measurement of resting metabolic rate. The children were then provided a caloric challenge, with metabolic measures taken at 30-min intervals for 150 min. Results showed stable resting and integrated diet-induced thermogenic responses across sessions. Differences in the pattern of response from 30 to 60 min were observed, with the response peaking earlier in the first session.This experiment was supported in part by Grant HD19532 NICHD awarded to the first author. 相似文献

Self-reports of depressive symptoms were obtained for 792 11-year-old New Zealand children using a structured interview. The aim of the present study was to test the hypothesis that depressive symptomatology in children is associated with impairment on cognitive tasks. The results did not support this hypothesis. Depression was unrelated to performance on various subscales of the WISCR, whereas self-reported inattention was associated with poor performance. Depressive symptoms, however, were significantly related to lower self-esteem and a poorer self-perception of scholastic ability.The Dunedin Multidisciplinary Health and Development Research Unit is supported by the Medical Research Council of New Zealand and the Departments of Education and Health, and involves several departments of the University of Otago. Much of the data are gathered by voluntary workers from the Dunedin community. The authors are indebted to the many people whose contributions make this ongoing study possible. 相似文献

The sexual harassment of junior, senior, and graduate student women and men by male and female professors, graduate assistants, and staff was investigated to determine students' personal experiences in the classroom, outside the classroom, and in job-related settings. Usable survey responses were returned by 393 students, and incidents were detailed by 38 women and 9 men who noted their responses to the harassment and its effects. Attitudes toward and acceptance of sexually harassing behaviors were measured by a 10-item Tolerance for Sexual Harassment Inventory (TSHI). The frequency of initiation of sexual behaviors was also assessed. More women than men reported being sexually harassed. Male and female perceptions of classroom behaviors were in agreement for most items. Men and women differed significantly on the TSHI, with men more tolerant of sexual harassment than women, and highly significant age differences were found, indicating a greater acceptance of sexual harassment by younger students. There was little difference between male and female students in the frequency of their initiating sexual behaviors. The TSHI was assessed; reliability coefficients and a factor analysis are presented.This research was supported by a grant from the College of Arts and Sciences. We are grateful to Betty Jones and Joan Bentley for their secretarial assistance. 相似文献

Pre-employment integrity tests assume differences between honest and dishonest individuals in their perceptions of the degree of dishonesty of given behaviors. This exploratory study investigated whether individuals classified as dishonest by an overt integrity test had different perceptions of the honesty of behaviors than those classified as honest. Differences in perceptions of situational factors promoting or deterring honesty were also examined. Dishonest individuals had different perceptions of behaviors and situations than honest individuals, suggesting that the relative influence of situational interventions may vary with the general integrity of a workforce. 相似文献

When childhood abuse trauma occurs in a Christian environment, the god representation is disrupted. Despite counseling, the impact of the god of childhood on the lives of child abuse survivors is often not resolved. The impact of the accumulation of child abuse trauma can seriously impair the development of the god image or even cause the god image to die. If a member of the family dies, there is a funeral and a period of socially supported grieving. When god dies, no one holds a funeral. The nature of the Christian god representation necessitates that Christian child abuse survivors grieve the loss of their childhood god if they are to resolve spiritual issues.An earlier form of this paper was given at the American Academy of Religion, November 1994. 相似文献

In the experiments described in this paper we examined the effects of contextual stimuli on pigeons’ recognition of visual patterns. Experiment z showed acontext-superiority effect. Specifically, two target forms that were identical except for location in the visual field were not discriminated when presented alone, but the compounds formed when each of these targets was placed between a nearby pair of flanking stimuli were readily discriminated. The size of the context-superiority effect decreased with increasing target-flanker separation. In Experiments 2 and 3 the two targets differed in form rather than spatial location and were readily discriminated in the absence of Hankers. Under these circumstances, adding an identical pair of flankers to each target resulted in a content-inferiority effect; that is, the two target-plus-Hankers compounds were less readily discriminated than the targets atone. The size of the context-inferiority effect decreased with increasing target-flanker separation. The observed effects of context are predictable from the Heinemann-Chase (1990) model of pattern recognition. 相似文献

A dichotic listening experiment was conducted to determine if vowel perception is based on phonetic feature extraction as is consonant perception. Twenty normal right-handed subjects were given dichotic CV syllables contrasting in final vowels. It was found that, unlike consonants, the perception of dichotic vowels was not significantly lateralized, that the dichotic perception of vowels was not significantly enhanced by the number of phonetic features shared, and that the occurrence of double-blend errors was not greater than chance. However, there was strong evidence for the use of phonetic features at the level of response organization. It is suggested that the differences between vowel and consonant perception reflect the differential availability of the underlying acoustic information from auditory store, rather than differences in processing mechanisms. 相似文献

Dichotically presented CV syllables were presented to 24 normal subjects under two contrasting performance requirements: consonant identification and consonant discrimination. In the identification task, subjects made more errors identifying stimuli distinguished by two as opposed to one distinctive feature. Conversely, in the discrimination task, subjects made more errors for stimuli distinguished by one as opposed to two distinctive features. It was proposed that the results of the identification task reflect the degree of information load in short-term memory. The results of the discrimination task, on the other hand, reflect the degree of perceptual similarity between contrasting stimuli. Both results were accounted for within a distinctive feature framework. Analyses of the individual features which comprised one and two feature distinctions demonstrated the perceptual prominence of the feature [voice] in contrast to the two place features [compact] and [grave]. 相似文献

In this study, we attempted to determine whether phonetic disintegration of speech in Broca's aphasia affects the spectral characteristics of speech sounds as has been shown for the temporal characteristics of speech. To this end, we investigated the production of place of articulation in Broca's aphasics. Acoustic analysis of the spectral characteristics for stop consonants were conducted. Results indicated that the static aspects of speech production were preserved, as Broca's aphasics seemed to be able to reach the articulatory configuration for the appropriate place of articulation. However, the dynamic aspects of speech production seemed to be impaired, as their productions reflected problems with the source characteristics of speech sounds and with the integration of articulatory movements in the vocal tract. Listener perceptions of the aphasics' productions were compared with acoustic analyses for these same productions. The two measures were related; that is, the spectral characteristics of the utterances provided salient cues for place of articulation perception. An analysis of the occurrences of errors along the dimensions of voicing and place showed that aphasics rarely produce utterances containing both voice and place substitutions. 相似文献
