This paper is a reply to an article in this journal by M. Zimmerman titled “The Home Observation for Measurement of the Environment: A Comment on Elardo and Bradley's Review”. We found Zimmerman's critique of our original review article (Developmental Review, 1981, 1, 113–145) to contain points which were well taken, and several which seemed pedantic. Specifically, we address his concerns about our discussion of the HOME scale's interrater reliability, test-retest stability, concurrent validity, and predictive validity; and we reply to his comments about the uses of the HOME scale for purposes of screening and matching environments. 相似文献

This article presents a model for training counselors to confront empathetically and presents a confrontation training scale that includes the inadequate responses of acquiescing and scolding and the progressively more effective responses of recognizing ineffective behavior, realizing its negative consequences, and committing to change. The authors contend that counselors who confront tend to become more empathic but also more able to help others and themselves face their problems responsibly. 相似文献

Most dimensional analyses of traditional Rorschach scoring categories have either failed to control for differences in total R or have done so by introducing a nonstandard mode of administration. Consequently, the results of such studies may be either distorted or of questionable relevance to more typical situations. The present analyses, which compared both group and individual forms of the Rorschach administered to large samples (over 500 each) of male medical students, controlled for differences in total R by using residualized scores from which the linear effects of R had been partialled. The factor-analytic results are expressed in terms of seven easily interpretable factors (including total R), five of which are similar across forms, and simple formulas for deriving norm-referenced factor scores from the data of individual test administrations are provided. 相似文献

Although performance expectancies have been shown to be important mediators of achievement behavior, few specific determinants of personal expectancies have been identified, the ecological validity of previous results is limited, and factors influencing group performance expectancies have not been determined. Therefore, the purpose of this field study involving 11- and 12-year-old male soccer players was twofold. First, we examined specific intrapersonal and situational factors influencing players' pregame personal and team performance expectancies. Second, we investigated the effects of winning and losing a competitive soccer game on players' postgame team expectancies involving a hypothetical rematch with the identical opponent. The pregame findings revealed that (a) the intrapersonal factors of ability and self-esteem were related to personal performance expectancies while competitive trait anxiety was not, and (b) the situational factors of past win-loss record and a prior game win or loss against the same opponent influenced team performance expectancies. The postgame findings revealed that future expectancies were affected by the interactive effects of game win-loss and self-esteem. 相似文献

In two experiments, water-deprived rats were exposed to tone-footshock pairings in a particular conditioning context. In Experiment 1, the training parameters were selected on the basis of parametric pilot data so as not to produce direct associations between the conditioning context and footshock. Despite independent evidence of no appreciable direct association between the conditioning context and footshock, animals tested in the conditioning context exhibited more lick suppression to the tone than other animals tested with the tone outside of the conditioning context. Thus, the conditioning context potentiated suppression to the tone in the absence of appreciable fear of the conditioning context. In Experiment 2, training parameters were used that permitted the formation of direct associations between the conditioning context and footshock; however, for half the animals, these associations to the context were then extinguished. With the tone absent, a comparison of extinguished animals tested either in the conditioning context or outside the conditioning context detected no differences in suppression, demonstrating the effectiveness of the extinction manipulation. However, other animals also subjected to extinction of direct context-footshock associations displayed greater suppression to the tone within the conditioning context than comparable animals tested outside the context. Collectively the data indicate that the superior retention-test performance seen within the training context can arise both from the commonly assumed direct associations between the training context and the unconditioned stimulus and from the potentiation by the training context of the associations between the nominal conditioned stimulus and unconditioned stimulus. 相似文献

Rats were trained to bar-press for water in the presence of a simultaneous compound tone-light stimulus using a discrete-trial procedure. Different groups were given between 300 and 3900 trials. When subsequently tested in extinction, all rats showed consistent levels of responding to the compound stimulus but responding to the tone and light components declined as a function of number of training trials. This is a demonstration of spontaneous configuring. Two other experiments showed that with similar procedures generalization from a component of the training stimulus to other values on the same continuum decreases with increased training with the compound stimulus. It was concluded that configuring and generalization from a single stimulus involve the same processes. 相似文献

The purpose of this paper is to demonstrate that rats can rapidly learn to locate an object that they can never see, hear, or smell provided it remains in a fixed spatial location relative to distal room cues. Four groups of rats were permitted to escape from opaque water onto a platform which was either just above or just below the water surface, and in either a fixed or varied location. Learning occurred rapidly except for the group for whom the escape platform was below the water surface and moved about from place to place. Transfer tests revealed that a spatial location search strategy was employed by the group for whom the platform was below water but in a fixed location. A second experiment investigated this learning further, revealing instantaneous transfer when the rats were required to approach the platform from a novel starting position. The data of both studies are discussed in relation to recent work on spatial memory in the rat. The concept of the “acuity” of spatial memory is introduced and the procedures used may provide a new approach to comparing spatial memory with classical and instrumental conditioning. 相似文献

Contrast and undermatching as a function of reinforcer duration and quality during multiple schedules 总被引:1,自引:1,他引:0 下载免费PDF全文

Eight pigeons pecked keys under multiple variable-interval two-minute variable-interval two-minute schedules. In Experiment 1, the reinforcers were 2, 4, or 8 seconds access to a food magazine. In Experiments 2 and 3, the reinforcers were grains that had been determined to be most-, moderately-, or non-preferred. Both positive and negative behavioral contrast occurred when the reinforcers in one component were held constant and the duration or type of reinforcer obtained in the other component varied. Undermatching occurred when the relative rate of responding during a component was plotted as a function of the relative duration of the reinforcers in that component. 相似文献
