The phenomenon of ear dominance for pitch described by Efron and Yund has been attributed by them to an asymmetry of sensory origin in the binaural integration of dichotic tone pairs. An explanation of this phenomenon in terms of an attentional bias is rejected on the basis of two experiments where the possibility of such bias was excluded. These and other experiments indicate that a simple explanation of this ear dominance in terms of a hemispheric specialization in the processing of tonal stimuli also must be rejected. 相似文献

The purpose of this study is to analyse the specificity of interactions between preschool friends, whose relationships are built on a voluntary and stable choice of a particular partner. The sample consisted of 18 unisexual triads of children aged 3 to 4 years (9 male and 9 female) from 5 Parisian kindergarten. These triads were compared with 18 others, composed of children aged 4 to 5 years (9 male and 9 female), from a previous study (Werebe et Boudonnière, in press). Each triad was composed of a dyad of friends plus a third familiar partner, all three classmates. The dyads of friends were selected on the basis of the following criteria: (1) a reciprocal and preferential search for one another; (2) a voluntary choice of the friend, without intervention from parents or teachers. The children were videotaped without their knowledge, without adult presence, in a familiar room of their school. The experimental setting was standardized in each of the 5 schools. The experimental paradigm was a variant of the one created by Nadel and Baudonnière (1980, 1982), with an important modification: the ten categories of matching objects were provided in double sets for the three children. Four indices were used for the data analysis: holding and appropriation of objects; offering of objects; competition to hold objects and verbalizations. The findings confirmed the principal hypothesis: that interactions between friends differ from those with the third partner, in both age groups, quantitatively (density of interactions) and qualitatively (reciprocal offerings and verbal communications). Furthermore, the findings revealed that the younger children had more difficulty than the older ones, to manage the triadic situation, especially in this situation with the constraint imposed by the presence of two sets of matching objects for three partners. 相似文献

A size-congruency effect in memory for visual shape 总被引:1,自引:0,他引:1
Pierre Jolicoeur 《Memory & cognition》1987,15(6):531-543
In five experiments, visual shapes were shown at either a small or a large size for study in the learning phase of a recognition memory experiment. Later, in the test phase, recognition memory was tested in anold-new paradigm in which an equal number of new shapes were mixed at random with previously seen shapes. Half of theold shapes were shown at the same size as in the learning phase, whereas half were shown at the other size. In every experiment, shapes tested at the same size as shown in the learning phase were recognized more quickly and more accurately than shapes tested at a different size. This size-congruency effect was found for line drawings of natural objects and for unfamiliar shapes (i.e., blobs and stick figures). Furthermore, the magnitude of the size-congruency effect depended on the degree of discrepancy between the learning size and the test size. Together, the results suggest that visual shape memory can be sensitive to the size at which patterns are originally encoded, and that the speed and accuracy of recognition memory is influenced by the size of a shape. 相似文献

The hypothesis that latent inhibition could be reduced by extinguishing the experimental context, that is, exposing the rats to the context between exposure to the conditional stimulus (CS) and conditioning, was tested. All experiments used the conditioned emotional response procedure. In Experiment 1, extinction was not effective when the animals were exposed to the clicker 40 times off the baseline of responding for food and when the clicker CS was partially reinforced with shocks during the test phase. In Experiments 2 and 3, latent inhibition could be reduced by extinction if the animals were exposed to the CS 24 or 16 times on-baseline, and if continuous reinforcement was used during the test. In Experiments 4, 5, and 6, we attempted to determine which variable was responsible for the discrepant results. In Experiment 4, extinction was effective with 20 or 40 on-baseline exposures to the CS, using continuous reinforcement during the test. In Experiment 5, extinction was not effective with exposure on- or off-baseline, using 24 exposures and partial reinforcement. Finally, in Experiment 6, extinction reduced latent inhibition using continuous, but not partial, reinforcement with 40 exposures off-baseline. From these results, we concluded that Wagner's model of habituation was not sufficient to account for latent inhibition and that a hybrid model, using both associative and cognitive representational processes, was necessary. 相似文献

This training study of the concept of class inclusion follows a previous paper on the training of the conservation of liquids (Dasen et al. 1979). Twenty-eight African (Baoulé) children, aged 7 to 9 years, were attributed to two groups, matched on age, schooling and performance on a pretest comprising 5 concrete operational tasks. Fourteen subjects who performed at stages 1 or 2 on class inclusion were trained according to a method adapted from Inhelder et al. (1974). The training effect was measured during two post-tests at the interval of one month. The results show a stable training effect in half of the subjects; there is a statistically significant generalization to other concepts of the same stage. This finding, which is similar to what has been reported for European children, supports the hypothesis of connections between operational concepts based on the common structure of the ‘grouping’. A ‘time lag’ of about 2 years in the development of class inclusion appears when comparing Baoulé and European children. The absence of very rapid learning (‘actualization’) shows that this lag probably occurs at the competence and not only at the performance level. The training effect is sufficient to reduce and even bridge this lag. 相似文献

Over the past decade there has been a growing interest on the part of educators, medical specialists, mental health personnel, and the lay public in the diagnosis, evaluation, and remediation of specific learning disabilities in the school-age child. This paper attempts to show through case illustrations of five high school-age adolescents how parents can seek from clinical evaluators a diagnostic impression of primary learning disability for their nonlearning disabled children; how this otherwise legitimate diagnostic category can be inappropriately used in the service of denying the salient individual, emotional, and family system factors at work in the school-related difficulties; and how the label of learning disability can work as a formidable resistance on the part of the family when, following comprehensive, in-depth assessment, professional recommendations focus less on specific educational remediation and more on the need for individual or family psychotherapy. Suggestions are made for dealing with this clinical issue. 相似文献

This paper summarizes and discusses the contributions of neuropsychological assessment to various forms of psychopathology. Emphasis is placed upon studies done with the Halstead-Reitan battery and the Wechsler Adult Intelligence Scale, but studies done with other neuropsychological test procedures are also reviewed. The conclusions reached are that neuropsychological tests are sensitive to functional regional brain disorganization in psychopathology, and that they are useful in the diagnostic process for a number of disorders including schizophrenia, psychopathy, mood disorders, and other psychiatric conditions. 相似文献

Visuomanual sinusoidal tracking is investigated in 5- to 9-year-old children. The proportion of successful performances steadily increases with age, but adult proficiency is never attained even by those who can perform the task. Moreover, the progress in proficiency—as measured by systems analysis techniques—is not monotonic and suggests the presence of distinct stages in the development of visuomotor coordination. Qualitative analysis of unsuccessful performance demonstrates that failures cannot be ascribed only to insufficient motor coordination and emphasizes the role of cognitive and representational factors even in such a simple task. 相似文献

Although the negative effects of abusive supervision are well documented, less is known about the individual differences that drive supervisors to be abusive. We use a self‐control perspective to understand the unique roles of both psychological and neurological characteristics of supervisors in the prediction of abusive behavior. Specifically, we find a positive relationship between narcissism and abusive supervision, whereas political skill and intrinsic neurological connectivity in executive control regions of the brain negatively relate to abusive supervision. Our results further show that the relationship between narcissism and abusive supervision diminishes for those who are strong in terms of political skill. In addition, neurological executive control moderates the relationship between political skill and abusive behavior. When connectivity in executive control regions of the brain is lower, political skill becomes a more important factor in reducing the display of abusive behavior. Overall, we demonstrate how combinations of characteristics (both psychological and neurological) can provide a more in‐depth understanding of the emergence of abusive supervision. 相似文献
