Experiments 1 and 2 compared, with a single-stimulus procedure, the discrimination of filled and empty intervals in both auditory and visual modalities. In Experiment 1, in which intervals were about 250 msec, the discrimination was superior with empty intervals in both modalities. In Experiment 2, with intervals lasting about 50 msec, empty intervals showed superior performance with visual signals only. In Experiment 3, for the auditory modality at 250 msec, the discrimination was easier with empty intervals than with filled intervals with both the forced-choice (FC) and the single stimulus (SS) modes of presentation, and the discrimination was easier with the FC than with the SS method. Experiment 4, however, showed that at 50 and 250 msec, with a FC-adaptive procedure, there were no differences between filled and empty intervals in the auditory mode; the differences observed with the visual mode in Experiments 1 and 2 remained significant. Finally, Experiment 5 compared differential thresholds for four marker-type conditions, filled and empty intervals in the auditory and visual modes, for durations ranging from .125 to 4 sec. The results showed (1) that the differential threshold differences among marker types are important for short durations but decrease with longer durations, and (2) that a generalized Weber’s law generally holds for these conditions. The results as a whole are discussed in terms of timing mechanisms. 相似文献

The MMPI and Rorschach are consistently ranked among the most widely used psychological assessment instruments across adolescent and adult clinical settings. Although there is an extensive research literature available on each instrument individually, relatively little research attention has been focused on the interrelationships between these measures. This article reviews the literature derived from 37 studies that have reported interrelationships between MMPI and Rorschach variables in adult populations. The results of these studies generally indicate limited or minimal relationships between the MMPI and Rorschach. A number of methodological issues, however, prevent drawing firm conclusions from the literature at this time. Directions for future research are discussed, including consideration of issues related to sources of alpha and beta error and the need for studies examining the incremental validity of combinations of Rorschach and MMPI data in prediction to relevant external criteria. 相似文献

This experiment examines how narrative context affects French subjects' selection of past imperfective (imparfait) vs. perfective inflections with different predicate types. Adults and 10-year-old children were asked to inflect verbs presented in their written infinitive form in two conditions: (a) in isolated sentences; (b) embedded in the beginning, middle, or end of narratives. Regardless of conditions, the adults rarely used theimparfait with punctual resultative predicates. In both conditions, the frequency ofimparfait was high with durative predicates, particularly with aresultative ones, but it varied with position in the narratives, being highest at the beginning and lowest at the end. Although the children also used the imparfait frequently with durative predicates, they overgeneralized it to punctual resultative ones, regardless of conditions and of positions. These results show that adult uses of the imperfective/perfective distinction are determined by both predicate properties and grounding in narrative context. The children are less sensitive to some predicate properties than the adults and they do not differentiate imperfective/perfective aspect consistently as a function of discourse context. 相似文献

A study was made of 328 personal advertisements sampled from a major daily Canadian newspaper. It was found that gender differences for desired companion attributes were consistent with traditional sex role stereotypes. Relative to the opposite sex, women emphasized employment, financial, and intellectual status, as well as commitment, while men emphasized physical characteristics. Physical characteristics were the most desired, regardless of sex. Secondary findings were that, for this sample, considerably more men than women placed ads, and that the mean age for both sexes was relatively high. The main findings were similar to those from earlier studies.The author was formerly a psychiatric social worker employed by the Greater Vancouver Mental Health Service in Vancouver, B.C., Canada. He is presently a doctoral candidate at Simon Fraser University in Vancouver. The author would like to thank Dr. Ted Palys for his comments. 相似文献
