A synchronous-reinforcement schedule is a type of schedule of covariation in which the onset and offset of the reinforcer covaries with the onset and offset of behavior. This study was a proof-of-concept demonstration of the efficacy of synchronous reinforcement for on-task behavior (completing a preacademic skill) and an evaluation of preschoolers' preference for this schedule in comparison to a more traditional schedule of reinforcement. Specifically, we compared the effects of a synchronous-reinforcement schedule to one in which continuous access to stimuli was delivered at the end of the session and yoked to the duration of on-task behavior that occurred during the session (accumulated reinforcement). Results showed the synchronous-reinforcement schedule was more effective for increasing on-task behavior and preferred by most participants.  相似文献

A multiple baseline design across participants was used to determine how teacher greetings affected on-task behavior of 3 middle school students with problem behaviors. Momentary time sampling was used to measure on-task behavior during the first 10 min of class. Teacher greetings produced increases in students' on-task behavior from a mean of 45% in baseline to a mean of 72% during the intervention phase. Teacher greetings represent an antecedent manipulation that can easily be implemented in classrooms to improve students' on-task behavior.  相似文献

An ABA'B design was used to evaluate the effects of choice on task engagement for 3 adults who had been diagnosed with traumatic brain injury. A yoked-control condition, in which tasks that were selected by each participant were assigned subsequently to that participant by a trainer, was implemented to help distinguish between the effects of task preference and choice. The results for all 3 participants indicated that permitting individuals to choose from a list of tasks increased on-task behavior.  相似文献

We evaluated an outcome management program for working with staff to improve the performance of adults with severe disabilities in a congregate day-treatment setting. Initially, observations were conducted of student task involvement and staff distribution of teaching interactions across students in four program sites. Using recent normative data to establish objective goals for student performance, management intervention was warranted in two of the sites. A six-step outcome management program was then implemented in the two sites. The program involved defining desired student and staff outcomes, systematic monitoring of the outcomes, staff training, and supportive and corrective feedback. The outcome management program was accompanied by increases in student on-task behavior and staff distribution of teaching interactions in both sites. The increases brought the levels of on-task behavior above the normative average; on-task behavior was maintained above the baseline average for over 1 year in both sites. These results are discussed in terms of the benefits of relying on normative data for objectively evaluating and improving service delivery systems. Discussion of future research needs focuses on applying the outcome management program to other settings and services for people with disabilities.  相似文献

The present study compares the effects of providing choice between activities or between materials for completion of activities on the on-task behavior of 4 boys with autism spectrum disorders. Results showed that the participants displayed higher levels of on-task behavior during the choice conditions than in the no-choice condition. However, the type of choice opportunity did not seem to have a differential effect.  相似文献

The present study was conducted to determine the effects of self-monitoring and a changing criterion with public posting phase on student on-task behavior and written language performance. Four elementary school boys participated and were enrolled in an urban-based, elementary-level resource room for students with learning disabilities. Self-monitoring procedures for on-task behavior included the students listening to a tone recorded at 60-s intervals and responding to the question, “Am I on-task?” Written language performance involved the students writing for a 10-min. session and counting and graphing the number of words written. During baseline conditions, student on-task behavior and written language performance were collected. During the self-monitoring conditions, the students monitored their on-task behavior and written language performance simultaneously. In the changing criterion with public posting condition, the students received their goal for the day's session prior to writing, wrote, and recorded whether they met their goal. While the results show a functional relationship between self-monitoring and on-task behavior, the data for the relationship between self-monitoring and written language performance were less compelling. A greater increase occurred when the changing criterion with public posting condition was introduced. Results suggest that self-monitoring changed on-task behavior; however, further research needs to be conducted to determine the conditions that would produce comparable effects for written language performance. Several implications for students and teachers and parent training were discussed.  相似文献

Two studies were conducted with children who displayed behavior problems to evaluate the effects of task preference, task demands, and adult attention on child behavior. In Study 1, we conducted brief functional analyses in an outpatient clinic to identify variables that facilitated appropriate behavior. For 8 of 10 children, distinct patterns of performance occurred; 3 children displayed improved behavior with changes in task demands, 1 child displayed improved behavior with a preferred task, and 4 children displayed improved behavior with changes in adult attention. In most cases, the children's parents carried out the assessments with adequate procedural integrity. In Study 2, we applied similar assessment methods to a classroom setting over an extended period of time. We identified independent variables controlling appropriate, on-task, and academic behavior for 2 children on two tasks, with slightly different treatment procedures across tasks for both children. In addition, the results of brief functional analyses for both children corresponded to the extended classroom assessments.  相似文献

Achievement disparities between American Indian students and non-American Indian peers are persistent and well documented. Student engagement is a promising target for intervention given its relation to academic achievement. This study investigated the relation between specific teacher practices (opportunities to respond [OTRs], praise, and reprimands) and classroom on-task behavior in an urban, public K–8 school that serves primarily American Indian students. OTRs and praise were positively associated with student on-task behavior, whereas reprimands were negatively associated with on-task behavior. Results from multilevel logistic regression indicated that OTRs significantly increased the likelihood that a classroom was highly on-task, whereas the reprimands significantly decreased the likelihood. Praise did not have a significant effect after controlling for the other variables in the model. Results are interpreted in a context of evidence-based instructional practices for increasing OTRs and praise, decreasing reprimands, and ultimately enhancing on-task behavior in an urban classrooms serving primarily American Indian youth.  相似文献

The relative effects of positive reinforcement, response cost, and the two contingencies combined when used as contingencies for correct academic responses were compared on the dependent measures of accuracy of academic performance and level of on-task behavior. Thirty-three fourth- and fifth-grade pupils served as subjects. A combination of between-group and within-group comparisons indicated that all three contingency systems increased academic performance and on-task behavior (even though on-task behavior was never directly reinforced), but differences in effectiveness between the systems were insignificant. Most importantly, treatment effects on academic performance and on-task behavior persisted following abrupt withrawal of treatments for all three contingency systems. These results confirm earlier speculations that the reinforcement of academic behavior is (a) more likely to positively influene both academic and on-task behavior than in reinforcement of on-task behavior, and (b) is much more resistant to extinction following abrupt termination of the program.  相似文献

The effects of variable-interval (VI) and fixed-ratio (FR) schedules of reinforcement for work-related behavior and an organizer for the work materials (behavioral prosthesis) were evaluated with 3 adults with severe or profound mental retardation. The participants had been recommended for study because of high rates of off-task and aberrant behavior in their daily vocational training programs. For 2 participants, VI and FR schedules resulted in the same outcome: more aberrant behavior than on-task and off-task behavior combined. The FR schedule nearly eliminated emission of aberrant and off-task behavior by the 3rd participant. Combining the behavioral prosthesis with FR reinforcement (FR+O) increased the proportion of time spent in on-task behavior by all participants under certain FR schedule parameters. Second-by-second analyses of the observation records revealed that FR schedules reduced off-task and aberrant behavior during work sequences (i.e., ratio runs), and FR+O led to a further reduction of these behaviors during postreinforcement pauses. Overall, the results show how organizer and schedule parameters can be adjusted to produce an optimized balance between productivity and reinforcement while undesirable behavior is minimized.  相似文献

This study investigated the relationship between on-task behavior and the academic performance of three low achieving and disruptive children in an elementary school special-education class. A number of researchers have postulated that the direct elimination of off-task or disruptive behavior is a necessary prior requirement when increases in academic performance are sought in special-education classrooms composed of low achievers with below-average socioeconomic environments. The present research program investigated this issue and measured the incidence of on-task behavior and its relationship to changes in the performance of a variety of academic tasks brought about by the opportunity to engage in daily free-time activities. Three children from a class of eight “educably mentally handicapped” students were chosen as target subjects, as their repertoires seemed to be especially defective. These children were observed by the first author for 90-minute sessions three days a week, and data regarding on-task behavior were obtained by the use of an interval recording technique. In conjunction with the teacher, the first author also monitored the academic performance of the children in six structured activities—answer completion from boardwork instructions, task completion from handout assignments, comprehension of reading assignments and vocabulary recognition, accuracy of direction-following to audiotaped instructions, quality of copied handwriting, and the matching of appropriate phonetic sounds to pictured objects and situations. Following baseline sessions during which both on-task and academic performance was measured, several experimental sessions were conducted during which free-time was given noncontingently. During these sessions, no reliable changes in student performance were observed. Subsequently, the teacher and experimenters defined a specified percentage of correct completion of each of the six categories of skill performance as necessary for the achievement of the free-time reinforcer, during each experimental session. As a result, both the academic productivity and the on-task measures of behavior were observed to increase, even though reinforcement was not directly contingent upon on-task behavior. The subsequent reinstitution of noncontingent free-time was followed by lower rates of both output and on-task behavior. The final reintroduction of contingent free-time for academic productivity again produced substantial increases in both work accomplished correctly and on-task behavior. Corresponding increases in productivity were noted for most nontarget children as well. While the present investigation has shown a high correspondence between productivity and on-task behavior, we must keep in mind that on-task behavior can be defined in many different ways. It remains possible that differences in the degree of correlation between outcome measures and the topography of “work” activity may relate to the degree to which the specific on-task behaviors measured are actually required for the outcome behavior. The failure of many researchers to identify a direct relationship between “appearances” and output may be inherently a measurement problem.  相似文献

ABSTRACT

There is limited empirical research regarding effective treatment for public masturbation. In the current study, the relative and combined effects of reinforcement of an incompatible habilitative replacement behavior and response blocking with guided compliance on masturbation and on-task behavior were evaluated for a seven year-old African-American female with a traumatic brain injury who masturbated in her regular and special education classrooms. Results indicated that response blocking with guided compliance was successful in reducing masturbation. However, response blocking with guided compliance and reinforcement of an incompatible response was most effective for reducing masturbation and simultaneously increasing on-task behavior.  相似文献

Robotics is emerging as a promising tool for aiding research on animal behavior. The possibility of generating customizable, controllable, and standardized robotic stimuli has been demonstrated through a number of behavioral assays, involving vertebrates and invertebrates. However, the specific appraisal of the nature of robotic stimuli is currently lacking. Here, we attempt to evaluate this aspect in zebrafish, through a within‐subject design in which experimental subjects are faced with three experimental conditions. In the first test, we investigated sociability by measuring zebrafish response to a conspecific separated by a one‐way glass. In the second test, we studied zebrafish behavior in response to a 3D‐printed zebrafish replica actuated along realistic trajectories through a novel four‐degree‐of‐freedom robotic platform. Last, we investigated fear responses in a shelter‐seeking test. In agreement with our expectations, zebrafish exhibited an equivalent preference for live and robotic stimuli, and the degree of preference for the robotic replica correlated negatively with the individual propensity to seek shelter. The equivalent preference for the replica and conspecific suggests that the appraisal of the target stimuli is analogous. The preliminary evidence of a correlation between behavioral responses across tests points to the readability of robotics‐based approaches to investigate interindividual differences.  相似文献

This study investigated the effectiveness of self-monitoring on the on-task behavior and vocational production rates of 5 elementary students with moderate mental retardation during biweekly pre-vocational workshop sessions. They were taught to use a recording form to monitor their behavior and were cued to monitor by audiotaped tones. A multiple-baseline design across tasks was used to demonstrate a functional relationship between self-monitoring and both on-task behavior and task productivity. Once this relationship was demonstrated, the monitoring form and audiotape were withdrawn through fading procedures. Results indicated that (a) self-monitoring increased both on-task behavior and vocational task production rates, (b) performance gains maintained while cues and monitoring forms were withdrawn, and (c) gains maintained over several weeks in the absence of prompts (i.e., forms and tones).  相似文献

ABSTRACT

The purpose of the present study is to evaluate the use of a reinforcement package with four middle school students who were below grade level in reading. Data were gathered, independently by two observers, for on-task behavior for the number of correct words read for a two-minute timed trial, and for book pre- and posttests. These data were gathered during Direct Instruction Corrective Reading Lessons. The participants earned points for increases in reading academic behaviors and on-task during the lesson. The effects of the reinforcement package were evaluated in an ABAB single case replication design. The overall outcomes indicate that on-task behavior improved from the low levels during both baselines and increased to high levels when the reinforcement package was in effect. Changes in reading rate were also dramatic with the largest increases found when the reinforcement package was in effect. Increases in pre- and posttest scores were noted for each of the participants. The advantages of employing consequences in conjunction with Direct Instruction reading materials and procedures were outlined. The role of enhancing academic skills of at-risk and children with disabilities was also outlined.  相似文献

Effects of reprimands and praise on appropriate behavior in the classroom   总被引:1,自引:0,他引:1  
The effects of positive consequences on appropriate behavior at the beginning of a classroom experience were examined during an academic program for students with behavioral and academic difficulties. The results showed that the use of reprimands alone was associated with high levels of on-task behaviors during the initial days of the class. The addition of praise produced no change in the rate of on-task behaviors or the level of academic performance. The withdrawal of all consequences caused significant decreases in on-task behavior and academic productivity. The subsequent use of praise alone led to an initial increase followed by a dramatic decline in on-task performance, resulting in no change in the average rate of on-task behavior relative to the use of no consequences. These results are consistent with previous findings indicating the importance of reprimands for maintaining appropriate classroom behavior. Speculations regarding potential roles of praise are briefly discussed.The authors wish to thank classroom teacher Bonnie Chatterton for her exceptional cooperation and effort, Mark Gunning for his valuable assistance in the data collection, and Ann Abramowitz for her helpful editorial comments.  相似文献

Behavioral self-control procedures, composed of self-assessment, self-recording, self-determination and administration of reinforcement, were introduced into a regular third-grade classroom immediately after a baseline period. The procedures produced a small and unstable increase in the level of on-task behavior in eight of the nine subjects. After a second baseline period, a cueing procedure was introduced, using a chart specifying on-task behavior. This enabled within-lesson changes in on-task behavior to be posted clearly for the children. The cueing procedure combined with the self-control procedures produced a high and stable increase in on-task behavior in all subjects.  相似文献

I investigated the differential effects of self-monitoring of attentional behavior and self-monitoring of productivity on on-task behavior and academic response rate. Subjects were four learning disabled children with significant attentional problems. Results indicated relatively equivalent increases in on-task behavior over baseline during all treatment phases. Academic response rate also improved under both interventions, with self-monitoring of productivity showing a superior effect for one subject, an equivalent effect for one subject, and less dear results for two subjects.  相似文献

Previous work suggests that an all-positive approach to child management can be effective. The present investigation extends these findings by examining the efficacy of an enhanced all-positive management system in the absence of a history of negative consequences. The on-task behavior and academic performance of 8 first- through third-grade children with academic and/or behavioral problems were observed in the classroom. Results indicated that, in the absence of a history of negative consequences, enhanced positive consequences were not sufficient to maintain on-task rates or academic accuracy at acceptable levels. The addition of negative consequences resulted in an immediate increase in on-task behavior and academic accuracy; a primarily positive approach appeared to be successful in maintaining these gains following the gradual (as opposed to abrupt) removal of the negative consequences.  相似文献

Using an alternating treatments design, we investigated the effects of self-recording and goal-setting on the on-task behavior and the mathematics productivity of five low-achieving elementary school students in a group of eleven students in Korea. We also examined which intervention students preferred after they experienced self-recording and goal-setting. Visual analyses of the data showed (a) increases in students' on-task and mathematics productivity levels contingent upon the implementation of both self-recording and goal-setting, (b) no differential effects of the two interventions, and (c) students' general preference of goal-setting to self recording. We interpreted these results as indicating that both self-recording and goal-setting are effective self-management strategies, but practitioners must consider the features of the interventions before selecting one from them, and future researchers must examine the effect of combining the two procedures.  相似文献
