In token economies, we typically consider the instructional opportunities available during the periods of token delivery, but may overlook educational opportunities available at the time of token exchange. The present studies examined the use of labelled tokens and routines in the token exchange period to teach alphabet letter recognition to economically disadvantaged preschool children. The children earned points for a variety of academic behaviors in an early morning classroom setting. At no time were alphabet letters introduced or taught during class. Later, during a midmorning token exchange period, operated according to a department store model, the children were given their points in the form of poker chips inscribed with upper-case alphabet letters. They were required to discriminate among these lettered chips before exchanging them for backup reinforcers sold in four or five stores. To assess alphabet letter knowledge, probe evaluations were periodically conducted in which questions requiring alphabet letter recognition and labelling were asked. The answers to these questions were not reinforced. Alphabet letter training during token exchange periods consisted of having a child display the lettered chips, whereupon a teacher asked a number of recognition-type questions. Wrong answers were corrected, and correct answers praised. The child was allowed to exchange the tokens when the number required for a purchase had been recognized correctly. The periodic probe evaluations revealed consistent increases in correct alphabet letter recognition and, as a byproduct, alphabet labelling was facilitated, even though not explicitly trained. Thus, once the letters were recognized, correct labelling shortly followed. The sequential training of new sets of letters was used to demonstrate experimental control within subjects for two children. A control for exposure to the letters was provided by using the labelled tokens, but requiring the counting of chips rather than letter discrimination in the exchange period for two other children. This procedure produced chance levels of letter recognition, which were subsequently improved when the discrimination procedure was added. Posttraining probes, conducted at one and three weeks after training when the labelled tokens and discrimination routines were no longer in use, revealed the same high levels of recognition and labelling performance found during training. Thus, it appears that labelled tokens may be used to teach discriminations during token exchange periods so long as responses are differentiated on the basis of relevant dimensions of the stimuli.  相似文献

Past studies have shown that disruptive behavior can be eliminated and attending behavior accelerated in an academic setting. The relationship between these behaviors and academic performance is not well understood. The effects of behavioral and performance contingencies on classroom behavior and on academic performance were investigated. The subjects, third-grade students from an inner city elementary school, were exposed to a series of conditions including baseline, behavior contingencies, performance contingencies, and a mix of behavior and performance contingencies using a reversal design. The students worked 100 randomly selected mathematics problems for 20 minutes each day during each period. Behavioral contingencies improved attending and decreased disruptions but did not improve performance. Performance contingencies increased per cent correct problems but attending declined and disruptions increased. The combined contingencies increased both performance and attending. The experiment was replicated with another class of children varying the sequence of conditions and the amount of token reinforcement that could be earned. The findings emphasized the importance of designing specific contingencies for specific target behaviors. Behavioral contingencies did not have the positive effect on performance often implied, nor were performance contingencies alone able to maintain acceptable classroom behavior.  相似文献

The effectiveness of a token economy system in producing improvement in the academic performance of children with Down's syndrome was tested. One group of seven children received token reinforcement for correct responses and showed significant improvement both in arithmetic and language. A second matched group of six children received only verbal praise for correct responses to the same instructional materials and failed to improve in arithmetic but showed significant gains in language. Re-test scores one year later revealed that the Token Group maintained its gains in both subjects whereas the language performance of the No-Token Group showed a significant decline.  相似文献

Numerous studies have demonstrated that disruptive classroom behavior can be decreased by delivering tokens contingent upon periods of time during which children do not engage in it or by removing tokens contingent upon its occurrence. To date, the best controlled of these studies have consistently reported the two procedures to be equally effective. However, in these studies, token contingencies have been combined with instructions regarding the contingencies. The present study compared these two procedures when no instructions were given regarding the token contingencies. Token delivery was not effective in decreasing disruptive behavior in any of the children, while a combination of token delivery and removal was effective for three of four children. The results suggest that the combined procedure may be effective with certain populations that are not readily controlled by instructions.  相似文献

We combined several single‐subject designs to assess the effects of contingent and noncontingent token reinforcement on moderate‐to‐vigorous physical activity (MVPA) exhibited by 4 preschool‐aged children. Higher overall levels and longer bouts of MVPA reliably occurred when tokens were delivered contingent on MVPA for 3 of the 4 children when compared to baseline (no token) and for 2 of the 4 children when compared to noncontingent‐token conditions. The present study demonstrated that the delivery of tokens contingent on MVPA can increase and maintain MVPA exhibited by preschool‐aged children, resulting in more MVPA than in baseline conditions and conditions in which tokens are awarded without respect to MVPA. These results demonstrate that token economies can be used to increase MVPA and they add to the evidence base supporting the use of token economies to address a range of behavior problems.  相似文献

The primary purpose of the present study was to compare the differential effects of token reinforcement, feedback, and response cost on the test performance of delinquent boys. Eighty students were randomly assigned to three experimental groups and one control group of 20 subjects each. Each experimental group received a standard and a modified administration of the verbal section of the WISC. For the token reinforcement group, the modified WISC administration permitted students to earn tokens contingent on correct responses; the response cost group forfeited tokens contingent on incorrect responses; and the feedback group simply received information regarding the accuracy of each response. The control group received two standard WISC administrations. The primary measure was the difference in verbal I.Q. scores between the standard and modified WISC administrations. Results indicated that the token reinforcement and response cost groups achieved significantly higher scores than the feedback and control groups. No significant differences were found between the token reinforcement and response cost groups nor between the feedback and control groups. The implications of these findings for clarifying the relationship between motivational condition and test performance are discussed.  相似文献

The efficacy of immediate tangible reinforcement in increasing appropriate visual attending for entire classes of deaf children was examined. The subjects were three classes (seven children each) in a residential school for the deaf. Boxes were installed on each child's desk, with lights that were flashed immediately contingent upon 10 sec of visual attending. Light flashes were backed up by M & M's, cereal bits, or tokens. In two of the classes, extinction sessions were also scheduled. For all classes, the reinforcement procedure increased visual attending by 50% or more, maintaining it at rates above 82%. Withdrawal of tangibles decreased attending back to baseline levels. The results support analysis of attending as operant behavior and demonstrate the applicability of reinforcement procedures in modifying these behaviors for young deaf children in a classroom setting.  相似文献

The effects of a token system on a teacher's rate of social contacts with her students were investigated in a public school kindergarten. A group of six children were observed daily during a 20-min handwriting lesson. The children were divided into two groups (A and B) of three children each. Five conditions were imposed sequentially: (1) baseline without tokens, (2) contingent tokens for Group A, noncontingent tokens for Group B, (3) contingent tokens for Group B, noncontingent tokens for Group A, (4) reinstatement of condition 2, and (5) contingent tokens for both groups. It was consistently observed that the teacher's rate of social contact was higher with the children receiving the contingent tokens than with those who received noncontingent tokens.  相似文献

In Study 1, the effect of making tokens contingent on correct performance of low social position preschoolers on the McCarthy Scales of Children's Abilitieswas examined. Preschoolers in a token reinforcement group scored significantly higher (mean=8 IQ points) than subjects in a control group. In Study 2, the effect of tokens on McCarthyresults was examined as a function of social position in a 2×2 design. The high social position control group scored significantly above the low social position control. The low social position token reinforcement group, however, performed as well as both the high social position control and token reinforcement groups. Use of systematic reinforcement contingencies to reduce test error is discussed.  相似文献

Following a baseline period, a token reinforcement program was instituted in three resource-room classes for very disruptive children where the children spent 1 hour per day. The only reinforcers used in the token program were those available to any classroom teacher, viz., free time in an activity area. The effects of the token program were evaluated in the three resource-room classes as well as in the homerooms of all students participating in the resource-room program. Following 4 months of the token program, a return to baseline was made in one resource classroom. As assessed by standard classroom observations, the token program was effective in reducing disruptive behavior in all three resource-room classes; and when it was withdrawn in one resource-room class, the disruptive behavior remained at a very low level in the resource room. Ratings by teachers in the homerooms showed a significant reduction in disruptive behavior, but recordings by homeroom observers showed no such reduction. Possible reasons for maintenance of low rates of disruptive behavior after withdrawal of tokens were discussed in terms of the type of reinforcers used.  相似文献

Sixteen pupils in a psychiatric hospital were assigned to two tutorial reading classes and balanced on six pupil characteristics and teacher preferences for the children. The effects of reward and cost procedures in a token program were assessed using both within- and between-subject comparisons in the following phases: (1) Baseline; (2) Token I, teacher evaluated and reinforced children for appropriate behavior; (3) Withdrawal of Tokens; (4) Token II, same as Token I; (5) Token III, same as Token I and II, but switched order of class meeting time; and (6) Self-Evaluation, students rated their own behavior and received prizes based on their rating, rather than the teacher's rating. The token program was markedly successful in reducing disruptive behavior and in increasing reading skills in both the Reward and Cost Classes, but there were no significant differences in the effects of the reward versus the cost procedure. While cost may be seen as a punishment procedure, there were no adverse side effects observed in the Cost Class at any time when the token program was in effect. The order of the classes was unrelated to the level of disruptive behavior or academic progress. The Self-Evaluative Phase, in which the students rated their own behavior, was included as an alternative to the abrupt withdrawal of tokens. In this phase, disruptive behavior remained at the previous low level.  相似文献

The effects of reward and cost token procedures on the social and academic behavior of two groups of elementary special-education students were assessed using a reversal design. Behavioral observations of three target subjects in each group revealed that both procedures were about equally effective in reducing rule violations and off-task behavior. Records kept on the daily arithmetic performance of all subjects showed that output doubled in both groups during the token phases, although accuracy remained unchanged. When students were allowed to choose either contingency, no pattern of preference was established. Small differences were found in teacher behavior: the reward procedure led to an increase in approval comments but cost procedures produced no changes in teacher behavior.  相似文献

There is a common fear that the use of a token economy in one classroom might harm pupil performance in situations where the contingencies are not in effect. This study investigated potential contrast effects on measures of children's productivity and attitudes toward teachers. Six children with reading deficits participated. A multiple baseline design was used to assess the effects of a token economy which was systematically introduced across three teachers. Dependent measures included two rating forms of teacher popularity and work rate on a programmed reading series. The results indicated that the token system was effective in increasing the children's productivity and that no consistent behavioral contrast effects occurred. Furthermore, children's attitudes toward teachers did not appear to be influenced by the token economy until only one teacher was not delivering tokens. At this point, her popularity declined until she also delivered tokens. The token economy manipulation appeared to have a specific, desirable effect on the targeted behavior (i.e., work rate) and had minimal negative or positive “side effects” on teacher popularity.  相似文献

The benefits of token economies have been widely established, however there are very few empirical studies on the effects of token reinforcement on the behavior of young children with autism. The establishment of conditioned reinforcers such as tokens may be important in interventions for children with autism. Token reinforcement was used to increase the attending behavior of a young child with autism during discrete trials instruction for academic and communication skills. A reversal design showed that token reinforcement sustained attending only when the back‐up reinforcer was available and was accessed immediately. The results extend and corroborate findings on token reinforcement reported in other applied settings and are also consistent with findings from basic research on conditioned reinforcement.

Four chronic mental patients, residents of a token economy treatment unit, were randomly assigned to an experimental or control condition and attended 10 thirty-minute treatment sessions. For the two experimental subjects, contingent reinforcement was received for interacting with each other according to instructions in four distinct phases of interpersonal behavior: talking to another person, attending and talking to another person, asking and answering questions in a dyad, and working cooperatively in the dyad to solve problems. The two control subjects were instructed to perform the same behaviors but received non-contingent reinforcement. The results indicated a strong contingent reinforcement effect on the performance of the treatment sessions' target behaviors. Several baseline, treatment, and post-treatment response measures indicated that the treatment effects had generalized to other areas of social behavior away from the treatment setting.  相似文献

Since the publication of experimental reports by Wolfe (1936) and Cowles (1937), that tokens could be established as conditioned reinforcers, many accounts have appeared on the implementation of token systems in human subjects. Tokens have been successfully used as prosthetic motivational devices in a great variety of situations and subjects, such as retarded children (Birnbrauer, Wolf, Kidder and Tague, 1965), adult psychotics (Ayllon and Azrin, 1969), delinquent children and adolescents (Tyler, 1967; Phillips and Wolf, 1968), low achievers in schools (Clark, Lachowicz and Wolf, 1968), emotionally disturbed children (Hewett, Taylor and Artuso, 1969) and in normal classroom settings (O'Leary, Becker, Evans and Saudargas, 1969). In these reports, administration of tokens usually produced an increase in the frequency of desirable social and productive behavior. However, none of these studies showed that the effect of the tokens depended on their role as conditioned reinforcers based on the standard exchange systems being used. No assessment was provided about the separate contribution of the social reinforcement operations involved in dispensing tokens in a social setting.A suggestion about the possible confounding effects of social reinforcement in token administration comes from the failure to establish token systems in subjects who are partially unresponsive to social reinforcement (Hamblin et al., 1970; Ribes and Souza e Silva, in preparation). The present research was conducted with the aim of isolating the effects of conditioned reinforcement as such—apart from those produced by the social reinforcement provided in the delivery of tokens.  相似文献

A token reinforcement system for the reduction of institutionalized behavior in a chronic psychiatric ward is described. Quantitative assessments were made of the effects of the system on five types of positively reinforced behavior, two types of unreinforced behavior, and two types of fined behavior. To assess whether these effects were a function of the token procedures, three experiments were carried out, the first removing tokens for a brief period, the second making tokens non-contingent on behavior, and the third removing fines in one area while maintaining them in another. The token procedures were found to be the source of the observed improvements.  相似文献

Bornstein and Quevillon (1976) demonstrated generalization from a 2-hour self-instructional training session to on-task behavior in the classroom with 4-year-old overactive children. In an attempt to replicate this work with older children, eight 7- and 8-year-old hyperactive children were assigned to either a self-instructional training group or an attention-practice control group. On-task behavior in the classroom and performance measures in reading and arithmetic were assessed. The level of difficulty of these tasks was varied. The results of Bornstein and Quevillon's (1976) study were not replicated, although the subsequent introduction of a token program significantly increased on-task behavior.  相似文献

After a period of equal reinforcement for choices of any job revealed which of 10 jobs each of 24 preschool children preferred and did not prefer, token payment became dependent on particular choices. Some children received tokens only for choosing previously non-preferred jobs, others for choosing previously preferred jobs. When tokens depended on choosing the nonpreferred jobs, those came to be preferred. When tokens depended on choosing the preferred jobs, the preferences were strengthened. The effects were replicated both within and between subjects, except in the case of one boy who consistently avoided token pay.  相似文献

The effect of token reinforcement on three classes of divergent verbal responding to verbal stimulus items from three measures of the Wallach-Kogan Creativity test was examined. The subjects consisted of two “gifted”, two “average”, and two “learning disabled” children from a public-school setting. The design utilized both an intra-subject and inter-subject multiple-baseline design with a reversal design added. Tokens were dispensed contingent upon the number of appropriate verbal responses to each stimulus item, i.e., a continuous schedule of reinforcement was used—one token per appropriate response. Interobserver agreement on “appropiateness” was 993%. The tokens could be used to “purchase” items listed in a “menu” format (e.g., ball and jacks—100 tokens). Consistently large effects of token reinforcement were observed, without generalization of effect across the three classes of behaviors, or conditions. These results support the works of Goetz and Baer (Journal of Applied Behavior Analysis, 1973, 6 , 209–217), Goetz and Salmonson (Behavior Analysis and Education, G. Semb, (Ed.), University of Kansas, 1972, 53–61), and Maloney and Hopkins (Journal of Applied Behavior Analysis, 1973, 6 , 425–434). Implications lie in continued experimental analysis of behavior approach to the concept called “creativity”. Additionally, implications are made in classroom application of assessing and intervening in the area of divergent responding for children with deficits in those areas.  相似文献
