The generally low degree of agreement between self-ratings on personality traits and ratings by others may be interpreted from the viewpoint that self-reports reflect people's experience of themselves but not necessarily their behaviors. A detailed analysis of self and other ratings on subjective well-being as a central dimension of human experience is consistent with this phenomenological view. Ratings of well-being were not significantly correlated with rated behaviors either in self-ratings or in ratings by others. Screening subjects in terms of avowed consistency and observability on a trait did not improve self-other agreement for well-being, nor did it replicate the individual trait effects reported by Kenrick and Stringfield (1980). Judgments by others were found to have poor interjudge reliability and to reflect biases associated with projection of own well-being and a halo effect organized around the subject's perceived friendliness or likability. It was demonstrated that pooling the judgments of several observers should not and does not lead to accurate prediction of the phenomenal personality, and that accuracy may generally depend on the level of self-disclosure. 相似文献

The stability and long-term correlates of both social withdrawal and sociability were investigated in a longitudinal study of normal children in kindergarten through the fifth grade. Both observational and peer assessment indices of withdrawal and sociability were considered; furthermore, a distinction was made between observed active versus passive solitude. Of particular interest was whether social withdrawal in early childhood was predictive of subsequent internalizing problems, as assessed by self-reports of social competence, overall self-worth, loneliness, and depression as well as teacher ratings of shy/anxious behavior, in later childhood. Results indicated a modest degree of stability for observed social withdrawal but not for observed sociability, nor for active or passive forms of solitude. Somewhat higher stability correlations were obtained for peer assessments of both sociability and withdrawal. In terms of predictive outcomes, significant relations were found between early social withdrawal in kindergarten and Grade 2 and subsequent internalizing problems in Grades 4 and 5, although the pattern of results was mixed. These data suggest that social withdrawal in early childhood may be predictive of risk for internalizing difficulties in later childhood. 相似文献

This study investigated the effects of methylphenidate (MPH) on inhibitory control in hyperactive children. A double-blind, placebo-control, within-subject (crossover) design was used in which 12 children, between 6 and 11 years of age, were each tested four times in each drug condition: 0.3 mg/kg and 1.0 mg/kg of methylphenidate, and placebo. Dependent measures included (a) the probability of inhibiting responses to a primary choice reaction time task given a stop signal, on the Stopping Task, and (b) response latency and errors on the Matching Familiar Figures Test (MFFT). MPH improved the efficiency of the central inhibitory mechanism by speeding the inhibitory process, thereby affording the children greater control over their actions and enabling them to increase the probability with which they inhibited responses given a stop signal. MPH increased response latency but did not reduce errors on the MFFT, and observation of the children's task performance highlighted the interpretive problems associated with this task. Performance on both tasks was better at a dosage of 1.0 mg/kg than at 0.3 mg/kg. 相似文献

Six subjects located, monaurally, 1.0-kHz-wide noise bursts whose source originated on the side of the functioning ear and whose center frequency ranged from 4.0 through 9.0 kHz (Part 1). Irrespective of their actual locations, the stimuli appeared to migrate from the frontal sector of the arc toward the side as the center frequency was increased above 4.0 kHz. For some subjects, the sounds appeared again in front at the higher center frequencies. Comparable data were obtained with noise bursts 2.0 kHz in width. We referred to these constellations of location judgments, influenced by the frequency composition of the stimuli, as spatial referent maps. In Part 2, we measured, by means of a miniature microphone placed at the entrance of the external ear canal, the pinna amplification function for these same stimuli emanating from the same locations. The results showed a positive relation between the apparent location of noise bursts centered at 6.0 kHz and above and the relative amplification provided by the pinna. Localization performances by two subjects, chosen on the basis of their noncorresponding spatial referent maps, were examined for stimuli of wider bandwidths IPart 3). Their proficiency differed markedly from one another, which we accounted for in terms of different spatial referent maps that were associated with differences in the pinna amplification function. 相似文献

The development of a technique for analyzing mothers' speech to young children is described. The need for such a measure arose from two linked studies of autistic children, one comparing them with developmental dysphasic children and the other evaluating the results of a home-based approach to treatment. A 17-category system was developed which could encompass almost all the types of speech shown by mothers of young autistic and normal children and which differentiated between the speech used by different mothers in a way that was meaningfully related to the child's level of language development. The categories proved to be easily applicable and to show good inter-observer reliability. Tape-recordings made during home observations were found to be the best source of speech samples. The problems of time sampling, length and nature of speech sample, and observer effects are discussed.We are most grateful to our colleagues Dr. Lionel Hersov and Mr. William Yule for many helpful suggestions in developing the measures and for their comments on an earlier draft of the paper. The study is supported by a grant from the (British) Department of Health and Social Security. 相似文献

This experiment explores semantic processing of one message while another is attended to and shadowed. It was an attempt to replicate and clarify an earlier finding by Lewis (1970). Like Lewis, we found that mean shadowing latency was increased when a synonym of the shadowed word coincided with it on the unattended channel. However, this occurred only with synonyms in an early list position and appeared to affect only a small proportion of trials. The implications of this and other recent findings for theories of selective listening are discussed. 相似文献

Monitoring performance was compared when subjects were asked to listen simultaneously for two different targets embedded in a sentence and when they listened only for one. The effects of different combinations of targets (phonemes, words, or meanings) were investigated and an attempt was made to separate the effects of particular combinations from the effects of difficulty of the two component targets. Performance was worse when either of two targets might occur than when subjects knew which single type to listen for. However there were no differences attributable to which particular types of targets were being combined. Listening for a phonemic target was as difficult to combine with listening for a semantic target as for another phonemic target. The result is consistent with a central speech analysing system whose limited processing capacity must be shared (at least in this monitoring task) both between and within all relevant levels of linguistic analysis, rather than with relatively independent subsystems for each type of listening. 相似文献
