The experiments compared the potencies of three different contingent time-out procedures for suppressing drinking in alcoholics, and also compared two different experimental methodologies for conducting such studies. In a residential research ward setting fourteen 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 the baseline condition subjects were free to drink with no behavioral restrictions. However during the time-out conditions, specific behavioral restrictions were imposed on the subjects for the 40-min period following receipt of each drink. The results showed that Social time-out suppressed drinking to 71 per cent of baseline conditions, while Activity time-out and the combined Social and Activity time-out suppressed intake to 36 and 24 per cent, respectively. The study also demonstrated that similar experimental results were obtained when subjects were continuously exposed to the experimental conditions for a number of consecutive days. or intermittently exposed to different conditions in a mixed order over successive days.  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

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

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

Pretreatment assessment data were used to enhance an existing treatment package to reduce aggression and to increase positive social interactions between a young boy and his peers. Based on the results of pretreatment assessments, additional reinforcement (differential reinforcement of alternative behavior with adult attention) and punishment (performing a nonpreferred task during time-out) components were added to an existing nonresetting differential reinforcement of other behavior (access to peers unless aggression occurred) plus time-out procedure. A posttreatment component analysis of the additional treatment components indicated that the reinforcement component facilitated positive social interactions and the punishment component suppressed aggression towards peers.  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

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

T D Crespi 《Adolescence》1988,23(92):805-811
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

Abstract

Effects of different levels of treatment integrity for a time-out intervention in relation to the aggressive behavior of an 18-month-old were investigated. The time-out intervention was composed of four steps and treatment integrity was systematically varied at 50%, 25%, 75%, and 100%. The results suggest that the 75% and 100% treatment integrity conditions were most effective for decreasing aggressive behavior. Further, there were only minor differences in aggressive behavior between the 25% and 50% treatment integrity conditions. Discussion focuses on the need for assessing optimal and minimum levels of treatment integrity for producing behavior change and the implications for classroom-based interventions.  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

Young children with surgically removed lenses and extreme nearsightedness can benefit from contact lenses, but their parents may need instruction to teach their children to accept lenses. In this study, 4 children under the age of 5 years were taught contact lens wear using a shaping procedure. Compliance was rewarded with praise and tangibles, and noncompliance was followed with brief time-out for 3 of the children and restraint for the 4th. Three children showed high compliance during an initial shaping procedure, with a decrease in compliance during initial insertion of the lenses. At 3- to 10-month follow-up, levels of compliance were high. Insertion and removal of lenses were accomplished in substantially less time, with little crying and no need for time-out. All 3 children continue to use the lenses daily, and 2 have shown improved visual acuity. The 4th child, who has Down syndrome, showed low levels of compliance with need for physical restraint throughout. Although his parents reported high compliance when he first went home, fitting difficulties and an infection resulted in plummeting of compliance, and contact lens use was discontinued. This procedure has been used successfully at the same hospital with 11 of 13 other children between the ages of 14 months and 7 years 4 months. Implications for selection of suitable candidates for this intervention and ways to decrease costs are discussed.  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

A questionnaire was administered to 200 college men and women. The instrument contained two identical sets of 45 items, each one describing a socially nonacceptable behavior. Subjects indicated whether their tolerance for the described behaviors was altered if they knew that the person was moderately intoxicated and whether they expected changed tolerance from others for inappropriate social behaviors when they themselves acted under moderate influence of alcohol. The general result indicated both reduced expected and displayed tolerance for alcohol-related social transgressions. This was interpreted as nonsupportive of the "time-out" hypothesis, according to which alcohol intoxication functions as an "excuse" for socially unacceptable behaviors. A minority of the respondents, however, both showed and expected extreme tolerance under alcohol and for this minority the "time-out" hypothesis might be valid.  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

This study tests the immediate impact of two interventions for intimate partner violent (IPV) men in affecting behavioral and emotional change during arguments with their partners. Couples with an abusive male partner (N = 100) discussed an area of conflict twice, interrupted by a brief intervention. Men were randomly assigned to receive (a) an editing-out-the-negative skills training, (b) an accepting influence skills training, or (c) a time-out. IPV men in both skills-training conditions showed greater decreases in aggressive feelings than IPV men in the time-out condition based on their self-report and observed affective behavior. Women also reported feeling less aggressive when their husbands were assigned to one of the skills-training conditions as compared to the control (time-out) condition. Results suggest that IPV men can learn to adopt new communication skills and that they do appear to have a positive impact on the emotional tone of their arguments. Clinically, communication skills training may be a useful addition to battering intervention programs, although these skills may need to be taught to both men and women involved in violent relationships.  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

Abstract

Time-out is a ubiquitous strategy to reduce problem behaviors. The current study sought to find the shortest effective duration(s) of time-out for sibling aggression in a community sample of girls ages 3–7. All participants reached a minimum reduction in sibling aggression of 60% after experiencing a 1-minute time-out. The majority (75%) of participants also demonstrated clear reversals of behavior when returned to the baseline condition. The current findings suggest that a 1-minute time-out may be sufficient for low-level sibling aggression in children as old as seven. Limitations include the presence of a graduate assistant during sibling play and unclear generalizability.  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

The effect of differential time-out (TO) durations (15, 30, 45, 60, and 90 minutes) on assaultive behavior for 13 psychiatrically hospitalized children and adolescents was analyzed. For the total sample, no statistically significant difference in assault frequencies was evident. Also evident was the effect of time-out duration on time taken to become settled: the longer the time-out given, the longer the time needed to become calm.  相似文献
