The conclusion reached by H. Thomas and W. Jamison (Developmental Review, 1981, 1, 274–283) that an observed sex-related difference in water-level task performance is due to an X-linked major gene raises the question of whether available data would be consistent with X-linkage predictions other than the one tested. Several predictions of X-linked inheritance for human characteristics are presented and discussed. It was concluded that although water-level task performance may involve a heritable component, the available data from seven independent studies reviewed by Thomas and Jamison are insufficient for determining the specific mode of genetic transmission. 相似文献

An alleged defect in transformational treatment of syntax acquisition is the absence from child speech of certain predicted errors with ‘wh-’ constructions. In this paper, a theory of acquisition dynamics and intensive longitudinal data are brought to bear on this issue. The key observations involve an early precursor, at 24—28 months, of the relative clause. The analysis sheds light on two fundamental issues in transformational acquisition theory: The permissibility of simultaneous rule changes and whether a transformation can be acquired before the associated deep structure. The issues and analysis can be translated into non-transformational terms. 相似文献

Five different performance-based treatments (participant modeling, participant modeling without therapist physical contact, modeling plus exposure, therapist-controlled exposure in vivo and rationale only) were compared to evaluate their relative effectiveness in the treatment of acrophobia. Ten subjects were assigned to each of the five groups. Avoidance behavior was assessed using a behavior test, self-report fear measures, heart-rate and self-efficacy expectation measures. Subjects were first submitted to two behavioral approach tests. These two pre-tests were administered 1 week apart, and no significant differences occurred between the evaluations. Analyses of variance for repeated measures at pre-test. post-test and follow-up revealed a significant improvement on all main outcome measures for the five groups. No significant differences among groups were observed. The total treatment time, which was also used as a dependent measure, did not yield any significant differences among treatment conditions. These findings have many implications. For instance, the need for induction aids, such as physical contact with the therapist and modeling, is questioned. Also, exposure per se whether therapist or self-controlled is shown to be effective in reducing avoidance behavior. Finally, the theoretical and clinical implications of these results are discussed. 相似文献

Thirteen obsessive-compulsive clients were treated with different methods of response prevention. Four experimental conditions were obtained through a 2 × 2 factorial design, in which the two main variables were varied: (1) gradual treatment vs flooding; and (2) modeling vs no-modeling. Clients were treated at their homes, three times weekly. Each session lasted 2 hr. Results at the post-test revealed, that modeling was superior to no-modeling (p < 0.05) on avoidance-other compulsions, therapist-rating only. On anxiety-main compulsions, clients rating the gradual method of treatment had been superior to flooding (p < 0.05). No other significant differences were found. 相似文献

Generalized imitation was established in three young subnormal children by reinforcing their imitations of a limited set of modeled actions in the presence of a large ball. A discrimination was then established by training nonimitation in the presence of a small ball. Imitation was then tested for various other ball sizes. Rate of imitation decreased as the test stimuli increasingly differed in size from the large ball. Imitations that were never reinforced occurred at about the same rate as those that were reinforced when in the presence of the large ball in training. 相似文献

Two experiments were conducted to investigate a modification of the Jones and Davis (1965) analysis of attribution. Subjects were confronted with a situation in which there were two possible causes for an event, and differential information about these causes was provided such that subjects were much more informed about the nature of one potential cause than the other. This information also imparted to the subjects a definite expectancy about the forthcoming event. When the event disconfirmed subjects' expectancies, responsibility was attributed to the cause about which least was known. This result was found in both experiments. In addition, Experiment II offered some suggestive evidence that a disconfirmed expectancy will lead the person to direct his attention toward potential causes about which he is uninformed. 相似文献

This study assessed the physiological and cognitive effects of Valins' (Valins, S. Journal of Personality and Social Psychology, 1966, 4, 400–408) false heart rate procedure. Twenty-two male subjects were exposed to two feedback conditions during which measures of actual heart rate and skin conductance were obtained. In each condition, eight slides of nude females were presented; some slides were associated with false heart rate increases, while for other slides the feedback remained stable. In one condition, subjects were told that the heart rate was that of another subject; in the other condition, subjects were told that the feedback was their own heart rate. In both conditions, subjects judged the attractiveness of the slides from their own point of view and from the point of view of the other subject. Slides associated with false heart rate increases were rated as more attractive than stable slides when subjects (1) heard their own heart rate and rated their own attraction; (2) heard the other subject's heart rate and rated their own attraction; and (3) heard the other subject's heart rate and rated the other subject's attraction. Skin conductance responses and actual cardiac decelerations were greater when subjects heard what was allegedly their own heart rate and when the slides were accompanied by apparent cardiac acceleration. However, these actual physiological responses did not play a causal role in relation to the affective judgments. Instead, the relationship between perceived physiological changes and feelings of attractiveness was mediated by cognitive processes associated with informational and directive influences of the feedback. 相似文献

Three possible sources of memory span growth were tested with a modified version of the digit span task using subjects 6, 8, 11, and 19 years of age. There was no developmental trend in facilitation due to experimenter-imposed organization of the input strings, ruling out simple input-organizational theories. The notion that children are deficient at organizing retrieved information was also found to be untenable. The data support the view that older subjects use more selective retrieval strategies, strategies which are better suited to the encoded material. The largest improvement in retrieval selectivity occurred between sixth grade and college. Recency effects were smaller for the younger subjects than for older subjects, with first graders showing significantly less recency than third graders, sixth graders, and college students. Improved item identification during input may account for this finding. 相似文献
