An experiment is presented which examined the influence of verbalizations on children's tendencies to postpone immediate gratification in terms of increased delayed reward. Children's verbalizations were varied in terms of their evaluative valence and whether they focused upon the reward itself or the delay task. During a delay task children in experimental groups periodically verbalized evaluative statements that were either positive (I like …) or negative (I don't like …) and which focused upon either the reward itself (… the tokens) or the delay behavior (… to wait). Children who focused on reward, under conditions of either positive or negative evaluation, postponed immediate gratification less than control subjects who made no verbalization. Children who evaluated delay behavior positively postponed immediate gratification longer than silent subjects, though children who negatively evaluated delay behavior did not differ from subjects who did not verbalize. The results are interpreted in terms of the influence of evaluative valence and focus as parameters of plans for delay behavior.  相似文献

The influence of overt self-verbalization on the maintenance of self-imposed delay of gratification was investigated in a task in which the child's possession of accumulating candy rewards was made contingent upon the child stopping further accumulation. Preschool girls who verbalized about the goodness of waiting and preschool girls who uttered an irrelevant verbalization waited longer before terminating their delay than did preschool girls who verbalized about the delayed reward or were silent. Second- and third-grade girls who verbalized about the goodness of waiting or who were silent waited longer than girls of the same age who verbalized about the delayed reward.  相似文献

Four experiments investigated the effects of a priming food reinforcement, given 0 or 75 sec pretrial, on runway performance of rats. The studies differed in the use of between-versus-within-subject designs, and by using food or water as the goal reinforcer. In Experiment 1, using food as the goal reward, subjects primed with food 0 sec pretrial conditioned slower than subjects primed 75 sec pretrial. In Experiment 2, using water as the goal reward, subjects primed with food 0 sec pretrial conditioned faster. These differences were evident on both prefed trials and on nonprefed test trials. Experiments 3 and 4 showed an opposite pattern of results when within-subject comparisons of 0- and 75-sec pretrial intervals were used: Food priming immediately pretrial facilitated food-rewarded running but inhibited water-rewarded running. The results suggest prefeeding has differential effects on acquisition and performance of instrumental behavior, and also depending upon the similarity of the priming and goal reinforcers.  相似文献

Previous research has found conflicting answers to the question of whether males and females share similar preferences for various job characteristics. It is difficult to determine if the different findings are due to the different populations sampled, the various methodologies employed, or to a real change in the phenomenon itself. This study essentially replicates earlier work by having 130 male and 84 female college students rate the importance of 10 job characteristics for both themselves and members of the opposite sex. Both sexes rated motivators as important, but females also placed importance on the hygienes. Males tended to underestimate the importance of the motivators for females, while females overestimated the importance of hygienes for males. The subject's sex could be predicted by both the importance for self and importance for opposite sex ratings, contrary to the earlier study. The difference in results and interpretation was shown to be due to the type of analyses used. Additionally, it was found that females' job preferences were related to their mothers' educational achievement.  相似文献

An experiment was devised in which subjects either were given a choice or were given no choice to listen to a counter-attitudinal communication. For half the subjects (Interrupt condition) the tape of the communication broke during the concluding sentence of the speech. The other half of the subjects (No Interrupt condition) heard the speech in its entirety. A recall measure indicated that subjects in the Interrupt condition recalled significantly more arguments made in the communication than subjects who heard the complete speech. This was interpreted as being a Zeigarnik effect caused by arousal created by the interruption. The choice manipulation should have created dissonance and motivated attitude change. Consistent with dissonance theory, measures of attitude change showed that greater attitude change toward the position of the speech occurred in the Choice condition than in the No Choice condition. In addition, an interaction in which significantly greater change occurred in the Choice-Interrupt condition than any of the other conditions was obtained. Since both the choice and interruption manipulations were hypothesized to be arousing, it was speculated that, in the Choice-Interrupt condition, the arousal created by the cognitive inconsistency and by the interrupted task may have combined to yield the increased attitude change. The conditions under which arousal states might combine were discussed.  相似文献

The present study investigated the effects of situational constraint and type of causal explanation on the degree to which described behavior would be perceived as evidencing “mental illness” and the degree to which it would lead to social rejection.Results showed that both of these variables influenced the degree of attributed “mental illness”, the degree of attributed psychological disturbance, and the degree of social rejection. Behavior inappropriate to a situation was rated higher on all three of these variables. Behavior attributed to external pressures received lower ratings on these variables than that attributed to internal causes, to organic causes, or for which no apparent explanation was available.  相似文献

The purpose of this experiment was to assess the reinforcing properties of sensory stimulation for autistic children. Three different types of sensory stimulation were used: music, visual flickering stimulation (e.g., strobe light), and visual movement (e.g., windshield wiper). In a given session, one of the three kinds of sensory stimulation was presented for 5 sec contingent upon the children's bar pressing (FR5). In Phase I, which was designed to assess the differential reinforcement value of these events, four children participated in sessions with each of the sensory events. In Phase II, designed to assess variables influencing the maintenance of responding for the sensory events, two children continued to participate in sessions with their preferred sensory event until satiation occurred. The results showed the following: (1) Sensory events could be used as reinforcing stimuli to produce a high rate of responding which was relatively durable over time: (2) the reinforcement function of the sensory events was idiosyncratic across children. with one child preferring one kind of sensory event, and another child preferring a different kind; (3) there was substantial variability in daily response rates: and (4) when a child satiated on a particular sensory event, a relatively small change in the sensory event was sufficient to recover a high rate of responding. The results of this study suggest that sensory reinforcers can profitably be used in behavior therapy with autistic children.  相似文献

This study was designed to test the hypothesis that systematic variations in listener behavior can have an important influence on both speaker behavior and communicative success among children. In particular, we investigated the idea that systematic variations in listener behavior might have not only within-trial effects on the adequacy of speakers' messages and the accuracy of communication among children, but also cumulative effects on speakers' initial messages across trials. Effects of stimulus complexity were also examined. Pairs of 7- and 9-year-old children participated in a referential communication game, with the younger child serving as speaker and the older one as listener. Half of the listeners were given a plan for effective listening which emphasized the importance of asking questions if the speakers' messages were ambiguous. Replicating earlier findings, the plan manipulation was successful in encouraging listeners to ask questions when necessary. The major result was that listener questions not only had the expected trial-by-trial effect on message adequacy and communicative accuracy, but also showed a cumulative effect on speaker performance. When exposed to systematic listener feedback, speakers improved their initial messages over trials. Stimulus complexity was not a major determinant of performances. These findings suggest that provision of systematic listener feedback may be an effective method for teaching speaker skills to young children.  相似文献

The performance of 80 preschool children on a reversal problem was studied as a function of amount of training and type of training procedure used during acquisition and reversal. In the extinction phase of reversal learning, subjects given a correction procedure during the reversal problem made fewer perseverative errors than subjects given noncorrection. In the reversal midplateau phase of reversal learning, overtraining facilitated reversal learning for subjects receiving noncorrection during the acquistion problem, but not for subjects receiving correction. A shift in training procedure between acquisition and reversal increased the number of subjects who reached criterion immediately after perseveration. Since these results are difficult to explain in terms of traditional learning theories, an alternative response-switching strategy explanation was proposed.  相似文献

The effects of censoring a communication, overriding the censor, and the attractiveness of the censor on the potential audience's attitude and desire to hear the communication were studied. Subjects were told that a speech which they were to have heard had been censored by a positively, negatively, or neutrally evaluated group. Some subjects were told that the experimenter had decided to override the censor and that they would hear the communication. Other subjects were told they would not hear the censored communication. The results indicated that censorship, regardless of the attractiveness of the censor, caused the potential audience to change their attitudes toward the position to be advocated by the communication and to increase their desire to hear that communication. These effects were interpreted as resulting from the arousal of psychological reactance. When the censor was overriden and the audience felt that they would hear the communication, their desire to hear it decreased. Further, subjects who had been told that a positively evaluated group had censored the speech changed their attitudes away from the position to be advocated by the communication while subjects who believed that a negative group had censored the speech changed their attitudes toward the position of the communication. These results were interpreted as evidence of cognitive balancing.  相似文献

The relationship between reward level and the basic motives which underlie strategic choices (competitive and noncompetitive) in a mixed-motive game was examined from two theoretical perspectives. The “regret” interpretation proposed by McClintock and McNeel was compared to an approach based upon Thibout and Kelley's concept of comparison level (CL). Two independent variables, CL and Reward, were manipulated by varying the payoff rates in two playing series of the MDG. Initially, 50 iterations were played for high (4¢ per point) or low (1 per point) incentive to provide subjects with outcomes upon which to base their CL's. The Reward manipulation was introduced in 150 subsequent trials of the game with subjects playing for 8¢ or 1¢ per point. The results show that the absolute magnitude of reward did not influence the extent of cooperative or competitive behavior. On the other hand, the magnitude of reward relative to CL was significantly associated with the degree of cooperative behavior—supra-CL outcomes yielding a higher frequency of cooperative behavior than infra-CL outcomes.  相似文献

Recent trends in sex-role research are reviewed with the purpose of showing a paradigm shift in the kinds of issues and questions thought to be important for an understanding of sex-role development. Two recent advances, conceptualizations of androgyny and sex-role transcendence are described with particular emphasis on the emergence of sex-role transcendence as a new theoretical construct. It is argued that while personality, social-learning, and structural-developmental theories account for sex-role identity and androgyny, only structural-developmental theory provides an adequate conceptual framework for the construct of sex-role transcendence. Questions are raised concerning the empirical demonstration of the concept.  相似文献

A subject was induced to publically report his opinions on a variety of issues. A group of confederates disagreed with the subject; one confederate agreed with him. Thus, the subject deviated from the majority of the group, but received social support from one other individual. Each subject was then paired with one individual from the previous group, and regardless of his pairing, was subjected to a constant amount of conformity pressure from the confederate on a new set of judgments. Deviant subjects conformed more to the confederate who had previously given them social support than they did to a previous majority member. This increased conformity was found in two studies, (1) females judging physical realities and, (2) males reporting their opinions on attitudinal issues. Ratings taken in the second study demonstrated that the deviant subject felt increased liking for and similarity to the confederate who initially provided him with social support, but comparisons between various experimental groups indicated conformity to a confederate was not completely predictable from the subject's liking for that confederate. Instead, conformity was greatest following an experience of deviation from the majority.  相似文献

First, third, and fifth graders (7.1, 8.8, 11.1 years old) performed semantic, acoustic, and orthographic orienting activities to different words in a list. Without forewarning, their free recall of the words was tested after the orienting activity. The semantic task yielded better recall than the acoustic or orthographic tasks, but the latter two did not differ. Age differences in recall were absent, and the effect of the three orienting tasks did not vary as a function of the child's age. The results support a direct extension of levels of processing theory (Craik, F. I. M., & Lockhart, R. S. Journal of Verbal Learning and Verbal Behavior, 1972, 11, 671–684) to children's memory. An obligatory-optional encoding distinction was suggested as a developmentally relevant addition to the levels of processing framework.  相似文献

The scope of Dulany's (1968) Theory of Propositional Control was examined using 54 1112-, 812-, and 412-year-olds. Significance of the reinforcer was manipulated orthogonally to value of the reinforcer. With a six attribute concept attainment task 412-year-olds did not learn in either of two significant ways: a performance change over blocks, nor the acquisition of a rule of reinforcement. Children of 812 and 1112 learned in both of the above senses. In addition, for the latter subjects the central equations of the theory held with strength and subjects' intentions accounted for more variance in performance than did the experimental manipulations. In supplementary experiments using a simplified task some 412-year-olds learned. When only the 412-year-olds who learned to a criterion were examined the central equations of the theory were nearly as strong as for subjects at ages 812 and 1112. There was no evidence for learning without awareness at any age level.  相似文献

A discussion of school psychology practice is presented, with emphasis on school programs rather than on individuals. While pressures exist to continue emphasizing the individual as the unit of study, current literature in evaluation theory and community psychology suggest a more viable model for the practice of school psychology. The learning process as it occurs in school programming is discussed, illustrating potential sources of involvement for school psychologists in effecting change in education. It is suggested that school psychologists, operating from a framework of evaluation theory, are well suited to be evaluators of school programs.  相似文献
