The purpose of the present study was twofold: (a) to determine the effect of an explanation prior to or after time-out on child compliance and on child disruptive behavior during time-out and (b) to determine the effect of brief parent training in time-out on child and parent behaviors. Thirty-two mother—child pairs served as subjects and were assigned to one of the following four groups: control, time-out only, explanation prior to time-out, or explanation following time-out. Each mother—child pair was observed for one session under pretraining, training, and posttraining conditions. The results indicated that time-out significantly increased compliance but the addition of an explanation did not further alter the effectiveness of time-out. Training in the use of time-out decreased the incidence of maternal interruptions but did not affect maternal responses that were not trained. Finally, following brief time-out training for noncompliance, the mothers used the procedure only 50% of the time following noncompliance.This study was supported in part by a University of Georgia Research Council grant.  相似文献

This study assessed the impact of a class-wide time-out/re-directing strategy on (a) the frequency of teacher-assigned time-outs and (b) the time students spent in disciplinary sanctions. Twelve students with emotional/behavioral disorders, enrolled in a self-contained elementary classroom were taught an alternative time-out strategy (Active Response Beads-Time Out), while teachers were taught a re-directing strategy, in an attempt to decrease the amount of student's time spent in time-out (TO) and the number of TO assigned by staff. Using a multiple baseline design across academic classroom periods, results showed that Active Response Beads Time-Out (ARB-TO) and teacher re-directions decreased the total time spent in time-out and number of TO assigned across the three class periods. Results maintained at one, two and four week follow-up sessions.  相似文献

Several factors affect the sensitivity to sleep deprivation in the performance of computerized tests. Two of these are task complexity and duration. Complexity can improve sensitivity by increasing the demands required to complete the task, but it can also decrease sensitivity by improving the subject’s motivation. The effects of task duration are more predictable in that longer tests generally are more susceptible to deprivation effects than shorter ones. The impact of task duration on an interesting, but complex, aviation simulation was examined here. By breaking down data from 30-min multi-attribute task battery administrations into the first, second, and third 10 min of performance, it was shown that tests shorter than 30 min underestimate the impact of sleep loss on performance. This was especially evident in measures of time-out and tracking errors.  相似文献

The effects of a movement suppression time-out, which involved punishing any movement or verbalization while a client is in the time-out area, were evaluated in four experiments. The first experiment examined the effects of a DRO procedure and movement suppression plus DRO in suppressing self-injurious behavior in a psychotic child in three different situations. In Experiment 2, the results of the previous experiment were replicated with two dangerous behaviors in a second psychotic child. In a third experiment, movement suppression plus DRO was compared with contingent restraint in reducing inappropriate poking behavior in two settings. The movement suppression procedure eliminated poking whereas contingent restraint had little effect. In the final experiment, movement suppression time-out alone was compared with exclusionary time-out alone and simple corner time-out alone. Self-stimulation occurred at high levels during the exclusionary and simple corner time-out procedures. Self-stimulation was either suppressed or reduced during movement suppression time-out. The movement suppression time-out procedure produced a larger reduction in the target behavior in all three children. The effectiveness of the movement suppression procedure was explained in terms of the suppression of self-stimulation while the time-out procedure was being applied.  相似文献

This project evaluated the effect of time-out release contingencies on changes in child noncompliance to maternal instructions. Twenty-four clinic-referred, noncompliant, preschool children served as subjects. Each child was assessed under baseline conditions and then under one of three experimental conditions: Parent Release, Child Release, or Control. Children in the Parent Release and Child Release conditions experienced time-out contingent upon noncompliance. Temporal and behavioral time-out release contingencies were present in the Parent Release condition but not in the Child Release condition. A spanking procedure was used to inhibit premature escape from time-out for children in the Parent Release group. The results indicated that both time-out groups demonstrated increased compliance ratios. However, improvement associated with the Child Release condition was considered to be clinically insignificant.The authors wish to express their appreciation to Dave DeLawyer, Larry Snapp, and Mike Samac for their assistance in conducting the study.  相似文献

In reviews published more than 30 years ago, eight parameters important to the use of time-out were identified and available research was summarized. The purpose of the current paper is to provide an updated summary of existing research for each parameter of time-out. Within each parameter, we conducted a thorough review of the published literature and identified all peer-reviewed articles addressing each parameter. We identified and summarized a total of 46 articles across the eight parameters, including 32 not cited in previous reviews. Sufficient findings were available to draw conclusions regarding time-out warning, schedule of time-out, contingent versus noncontingent release, and duration. Tentative conclusions based on only a few studies could be drawn in regard to instructional versus physical administration and verbalized reason for time-out. No conclusions could be drawn regarding time-out signal and specific time-out location. While we know much more today regarding effective implementation of time-out, there is a clear need for further exploration within these identified parameters. In addition to summarizing the literature, we reviewed recommendations made by behavioral parent training programs, parenting books, and parenting Web sites, and compared how well their recommendations matched current research based on the conclusions drawn from our review. We found that parenting sources made strong and specific recommendations on several of the parameters that were either not consistent with available research or simply lacked a sufficient research base.  相似文献

The present study examined the effects of two time-out (TO) procedures, within-room and out-of-room, on compliance and oppositional behavior. Subjects were 24 nonclinic 5-year old children and their mothers. Mother-child pairs were assigned to one of three groups (within-room time-out, out-of-room time-out, or control) and observed in a laboratory setting under each of three experimental conditions: pretraining, training, and posttraining. The results indicated that, relative to the control group, both out-of-room and within-room TO reduced oppositional behavior and increased compliance. The two time-out procedures were equally effective in changing the two target behaviors; however, the within-room approach required significantly more administrations of time-out than the out-of-room technique.  相似文献

We investigated the impact of contextual variation on the effectiveness of two interventions. The problem behavior of 2 students with severe disabilities was analyzed across two contexts (task and leisure). Effects of differential reinforcement of other behavior (DRO) and time-out procedures were examined in the two contexts. Results indicated that in the task context the DRO procedure effectively reduced the problem behavior and increased task performance, whereas the time-out procedure was ineffective. In addition, rate of correct task performance increased during DRO relative to baseline and time-out. In contrast, in the leisure context, the time-out procedure effectively reduced the same problem behavior and the DRO procedure was ineffective. The results are discussed in terms of contextual control of problem behavior and alternative strategies for the design of DRO procedures.  相似文献

We evaluated a commonly used component of brief time-out, in which release from time-out is delayed contingent on the occurrence of disruption. Data were collected for one normal and two mentally retarded children on time-out-producing behaviors (aggression and disruption) as well as delay-producing behaviors during time-out (loud vocalizations, out-of-chair, aggression, and disruption). The results of a combination ABAC reversal and multiple-baseline design indicated that, under the conditions used in this investigation, both delay and no delay variations were effective in reducing the frequency of the target behaviors. Implications for the use of time-out to reduce aberrant behaviors are discussed.  相似文献

A variable-interval timer with an audible tone output was designed to pace participants in human-factors studies. The timer can be operated in a continuous (recycling) mode or in a time-out (“beat-the-clock”) mode. In the continuous mode, the audible tone is emitted at the end of the preset interval and a new timing cycle is begun. In the time-out mode, the research participant must depress a switch both to avoid the tone and to begin a new cycle. The time interval can be digitally programmed for intervals from 1 sec to 2 h and 45 min. The operation of the timer is described, and construction details are provided.  相似文献

This study examined the extent to which competence in applying behavioral procedures (timeout from positive reinforcement) was sufficient to establish competence in teaching others to apply the same procedures. During baseline, graduate students attempted to instruct parents with a history of child abuse and neglect in the use of time-out. Students were then instructed in the use of time-out until they achieved proficiency in a role-play context. They then reattempted to instruct the parents. Finally, the students were instructed in certain consultation skills (i.e., teaching others to apply behavioral procedures) and again attempted to instruct parents in the application of time-out. Observations of students' consultation skills, parents' proficiency at administering time-out, and children's compliance to parental instructions revealed that explicit training in behavioral consulting skills was necessary to produce improvements in these behaviors. Students' proficiency at administering time-out was insufficient to enable them to instruct others in its application. These results were corroborated by surveys of both students and staff. The implications for graduate training and service delivery are discussed.  相似文献

Pecking was reinforced by a fixed-ratio schedule with food, and responses during a red light produced a time out. If the bird did not respond during the red light, the light terminated and the bird could complete the FR schedule of positive reinforcement uninterrupted. The bird stopped responding during the red light sufficiently to avoid most of the possible time outs. In general, the pre–time-out stimulus suppressed responding more when the FR schedule was large than when it was small. The occurrence of the pre–time-out stimulus in the fixed ratio produced FR strain and extreme curvature atypical of normal fixed ratios of this size. Amobarbital, pentobarbital, chlorpromazine, and d-amphetamine injected when the FR performance was strained by the pre–time-out procedure produced marked increases in responding. The drug administration lowered the rate of responding only at larger doses; and then this occurred predominantly just after the injection.  相似文献

In each of two experiments human subjects were intermittently reinforced with money on a fixed-ratio schedule for emitting correct matching responses. A pre-time-out stimulus which signaled removal of positive reinforcement was periodically superimposed. In the first experiment the superimposed pre-time-out stimulus was paired with a 1-min or 4-min response-independent time out. In the second experiment the pre-time-out stimulus was paired with a 1-min or 4-min time out contingent on the incorrect responses. The pre-time-out stimulus did not markedly influence performance when the time out was response independent. In contrast, the pre-time-out stimulus markedly suppressed incorrect responding when the time out was contingent on the incorrect responses. When duration of this time-out was increased from 1-min to 4-min, suppression of incorrect responding increased and correct responding was suppressed. Therefore, behavioral suppression by a pre-time-out stimulus was obtained only when the signaled aversive event-time out-was response produced. In this case, suppression was influenced by time-out duration.  相似文献

ABSTRACT

Maternal preference and acceptability were examined for two methods of addressing time-out escape behavior: room time-out (RTO) and deferred time-out (DTO). With respect to preference, mothers were split about evenly. Spanking frequency and previous effectiveness using privilege removal were associated with preference for DTO while previous effectiveness using RTO was associated with preference for RTO. Child age was negatively associated with acceptability for either treatment and lax parenting style was negatively associated with acceptability for DTO. Results suggest that DTO could provide an alternative escape contingency for mothers who spank their children or who have been unsuccessful using RTO.  相似文献

The effectiveness of a time-out intervention for adolescent psychiatric patients, adjudicated (delinquent) youth, and behaviorally disordered youngsters was explored in this study. The research was conducted in three psychiatric hospitals for children and adolescents, a facility for adjudicated youth, and in a day-treatment program. Utilizing a comparative outcome model, 813 occurrences of time-out with 274 youth were investigated in order to assess levels of effectiveness. The results indicated that time-out had a significant impact, and the use of a child-care specialist as time-out monitor improves overall effectiveness. Important implications for practicing professionals and clinical researchers are noted.  相似文献

One component of a well-researched, standardized parent training program is to spank children for escape from time-out. The contribution of the spanking component to compliance acquisition in a clinic analog setting was evaluated. Time-out duration and child disruption at time-out release were balanced across spank and no-spank (“barrier”) conditions. Sixteen noncompliant, clinic-referred preschool children participated. The data indicated that both spank and barrier procedures were equally effective at increasing compliance ratios. Physical punishment did not appear to be a critical component. Given prior research, it was concluded that the enforcement of a minimum time-out duration is critical for compliance acquisition within the analog setting.  相似文献

通过三个实验,研究了注意瞬脱效应以便深入理解注意时间维度上的特性。实验一针对注意瞬脱效应(简称AB效应)和刺激持续显示时间(简称ED)之间的关系,发现SOA或者ED的延长能减小AB效应。实验二的结果再次证明ED的延长能减小AB效应,并且发现ED延长并没有伴随着对目标的加工速度的加快。实验三发现在目标与干扰项没有显著的特征差异时,AB效应随着ED延长而减小的现象消失了,即ED对AB效应的影响出现了实验性的分离。同时还证明突出显示可以通过加快对目标的反应速度来显著的减小AB效应,而且ED因素只有在目标具有突出的视觉特征时才能改变AB效应。  相似文献

Mothers of twenty-four noncompliant, clinic-referred, preschool children were trained to use either a warned or unwarned time-out procedure in a clinic analog setting to suppress child noncompliance to commands. Warnings respecified the command to be followed and labeled the time-out procedures were equally effective at increasing child compliance. However, warned time-out procedures were associated with fewer actual time-outs than unwarned time-out procedures. The potential benefits of warned time-out procedures are discussed and future research needs are indicated.  相似文献

Conditioned acceleration and conditioned suppression in pigeons   总被引:1,自引:1,他引:0       下载免费PDF全文
Two experiments were performed to investigate the effects on pigeons' keypecking behavior of stimuli that signal different kinds of aversive events: time-out from positive reinforcement, electric shock, loud noise, and loud tone. Behavior maintained by a variable-interval schedule of reinforcement was suppressed by a stimulus before shock, was accelerated by a stimulus before time-out from positive reinforcement, and was unchanged by a stimulus before loud noise or a stimulus before loud tone. Conditioned acceleration with time-out from positive reinforcement and conditioned suppression with shock were obtained regardless of whether a response contingent or response-independent procedure was employed.  相似文献

In a residential research ward setting six volunteer chronic alcoholics were given daily access to 17 alcoholic drinks provided that a minimum of 40 min elapsed between receiving successive drinks. Each drink contained 1 oz 95-proof ethanol in orange juice. During baseline phases subjects were free to drink and socialize on the dayroom. However, during social time-out phases subjects were not permitted to socialize for the 40 min period following receipt of each drink. This contingent social time-out manipulation was systematically replicated across three conditions which varied with respect to the number of non-contingent ward privileges available. The results show that contingent social time-out suppressed drinking; and its effectiveness depended directly upon the conditions of available privileges. Within individual subjects, contingent time-out was increasingly effective in suppressing drinking as the available privileges were increasingly restricted.  相似文献
