Simple motor reaction times (right-handed) to tape-recorded consonant-vowel syllables were obtained from 12 subjects under two conditions of monotic stimulation: “expected” presentation (subject informed as to ear of presentation) and “random” presentation (ear of presentation varied randomly). Significantly faster left ear reaction times were obtained in the “expected” condition. The rank order of subjects' standard dichotic listening task scores correlated negatively with reaction time ear differences in the “expected” presentation condition. Results are discussed in terms of existing theories of response lateralization in simple reaction time tasks, and an expanded hypothesis is offered. Specifically, it is suggested that two or more distinct but potentially overlapping mechanisms may be responsible for observed asymmetries in monotic auditory perception. Both an attentional or lateralized motor response bias and an inherent lateralization of function may operate side by side, differentially activated by task demands, mode of stimulus presentation, and nature of stimuli.  相似文献

One-hundred and four women were tested on an eyelid conditioning paradigm in a 2 x 2 x 2 factorial design where two levels of US intensity (1 vs 3 p.s.i.) were balanced against two rest pause interpolations (after 25 and after 50 trials), and the presence or absence of a warning stimulus prior to CS-US presentation. Subjects were later classified as high, low or intermediate extraverts on the basis of a personality questionnaire. A very detailed analysis of conditioned responses was carried out, using both simple and composite measures including work-ratio, utility-ratio, CR frequency, peak latency, peak amplitude, response area and effective response area, degree of avoidance amplitude and latency, etc. Major findings related to similar effects of high intensity US vs low intensity US, and introversion vs extraversion; introverts react as if they were responding to more intense stimuli than extraverts. This finding cuts across other parameter variables, and supports Eysenck's formulation of personality-conditioning relationships in terms of higher cortical arousal in introverts as compared with extraverts.  相似文献

The present research conceptualizes life structure, or the pattern of life, as the ordering of priorities among competing alternatives. Intentions to emphasize career, marriage, or both were investigated for college students. Variations in these intentions were seen as resulting from differences in two classes of variables: (a) the perceived consequences of emphasizing the alternative; and (b) perceived normative pressures. A subjective probability model of the relationship between beliefs and behavioral intentions was used as a framework for determining the importance of these factors. The considerations identified as most likely to have a direct impact on life structure dealt primarily with interpersonal relations, particularly marriage and family. In general, the data suggested that the subjective probability model may be useful for further understanding of life structure decisions.  相似文献

The purpose of this study was to determine whether LD children exhibited problems in the processes of attention, memory, or syntactical awareness when decoding written prose. Eighteen LD children and 18 normal controls were matched for initial word recognition skills. Subjects were then trained to read a list of individual words to criterion. Subsequently, they were tested on their ability to decode the same words in paragraph form, presented both immediately after training, and then again one week later. Half the children read paragraphs following standard English syntax, while the other half read a syntactically scrambled version of the same paragraph. The results indicated that a major contributing factor in the reading (decoding) difficulties demonstrated by the LD children derived from problems of acquisition and retrieval from long-term memory storage. The results were discussed in terms of their implications for the developmental lag theory of learning disabilities.  相似文献

The job experiences of a group of young people of English and Pakistani origin who had left school four years earlier at the age of 16 were investigated using interviews and retrospective data from careers-office files. Job-changing had been frequent during the first 18 months of employment, with changes being largely of a non-promotional kind. Those who had experienced regular non-promotional job-change tended to have had low attainment in basic educational skills and inadequately developed vocational attitudes and personalities when leaving school. Yet in the majority of cases early mobility had led to stability by the end of the fourth post-school year. It is suggested that early job-changing may serve a positive function for the individuals concerned Implications for careers guidance in school are discussed.  相似文献

Eysenck originally postulated that extraverts would adopt tough-minded social attitudes, although psychoticism is now considered to be of greater importance than extraversion. Previous research has attempted to relate psychoticism to realism-idealism, a principal factor of the Wilson-Patterson Conservatism Scale, and a measure of tough-mindedness acceptable to Eysenck. Results have proved discrepant; authors have used psychoticism scales of uncertain item content and length. The present study examines the relationship between psychoticism, extraversion and realism-idealism, using the Eysenck Personality Questionnaire and the Wilson-Patterson Attitude Inventory. The results provide only weak support for Eysenck’s theory. A more significant relationship was obtained between psychoticism and conservatism, and extraversion and conservatism, although a theoretical rationale for these relationships is lacking.  相似文献
