An interrupted time-series analysis of local directory-assistance calls in the Cincinnati area from 1962 to 1976 revealed a significant reduction in the daily frequency of calls after charges were introduced in 1974. No reductions occurred in the daily frequency of long-distance directory-assistance calls, which remained free. The results attest to the efficacy of response-cost procedures with large subject populations in the natural environment. The applicability of response-cost procedures to social and business problems is discussed.  相似文献

Fifteen overweight girls aged 5 to 11 yr were randomly assigned to one of two weight-reduction treatments: response-cost plus reinforcement, response-cost only, or a no-treatment control group. In the response-cost plus reinforcement group, parents contracted to facilitate their child's weight loss by carrying out reinforcement and stimulus control techniques, completing weekly charts and graphs, and encouraging their child to exercise. The response-cost only group parents did not contract to reinforce their child's performance. The response-cost program applied to both experimental groups was conducted in weekly meetings in which parents lost previously deposited sums of money. Twenty-five per cent was deducted for missing the weekly meeting, 25% for failing to fill out charts and graphs, and 50% if their child failed to meet her specified weekly weight-loss goal. At the end of the 12-week treatment period, both experimental groups had lost significantly more weight than the control group. After an eight-week, no-contact follow-up, some of the lost weight was regained. The response-cost plus reinforcement group was still significantly below the controls. The response-cost group just missed significance. A 31-week, no-contact follow-up failed to show a treatment effect, but did show a trend towards slower weight gain by the response-cost plus reinforcement group.  相似文献

The study sought to motivate college students to reduce the number of miles they drove each day and thus save gasoline. Students in two psychology classes were divided by class into two groups. The experimental group was offered various combinations of prizes such as cash, a tour of a mental-health facility, car servicing, and a university parking sticker for reducing driving. The value of the prize received was scaled in terms of per cent reduction in driving. The contrast group received no inducements. The condition in which the experimental group's mileage reduction was reinforced was counterbalanced by two baseline conditions. Several special recording procedures were used to reduce and detect the possibility of subjects altering their odometers, the source of the driving data. Experimental subjects reduced their average daily mileage by 20% relative to the initial baseline; the contrast group did not change. During the one-month reinforcement condition, the 12 experimental subjects saved some 170 gallons (worth $102) of gasoline.  相似文献

A 39-year-old male presenting with a 5 year history of excessive urinary frequency and urgency was treated first with scheduling of urination, use of external urinary catheter and progressive muscular relaxation and then with a urinary retention training procedure. After the first set of procedures, urinary frequency decreased, whereas urgency increased slightly. After completion of retention training, both symptoms were alleviated. Overall, urinary frequency decreased from a baseline average of 14 urinations daily to a post-treatment average of 6.5 urinations per day. Urinary urgency decreased from a baseline average of 35 urges per day to a post-treatment average of 9.3 urges per day. Gains were maintained at 3 and 5 month follow-up.  相似文献

This study examined the effectiveness of several behavioral techniques on compliance of college students taking vitamin C on q.i.d. regimen. Compliance was assessed by a new technique using a variation of the urine tracer procedure designed specifically for this study. Subjects were provided vitamin C tablets, with three tablets per week containing phenazopyridine, a drug that produces a bright red-orange urine discoloration. Subjects were requested to indicate when urine discolorations occurred, and compliance was assessed by comparing the time of their report to the time predicted on the basis of the scheduled sequence of vitamin C and phenazopyridine tablets. Baseline compliance was assessed for 72 subjects over a three-week period, with the 40 most noncompliant subjects randomly assigned to four groups for Treatment I. The groups were: self-monitoring, taste, taste and self-monitoring, and a no-treatment control group. The self-monitoring procedure involved recording the time medicine was taken; the taste procedure involved providing the subjects with flavored tablets to increase the saliency of tablet taking; and the self-monitoring and taste procedure involved providing subjects with flavored tablets and asking them to record the flavor of each tablet they ingested. At the end of six weeks, half the subjects in each of these groups participated in response-cost procedures while the remaining subjects continued with their previous procedures. Response-cost procedures were implemented by returning a portion of the subjects' deposit only if a preset compliance criterion was met. Treatment II procedures were implemented for an additional three weeks. Results indicated the self-monitoring and taste plus self-monitoring procedures were superior during Treatment I. The implementation of response cost during Treatment II was associated with a marked improvement in compliance, independent of the history of noncompliance. The effects of the taste plus self-monitoring procedure were maintained during Treatment II and results obtained by this procedure were not significantly different from effects of response cost.  相似文献

This paper reports an investigation of American and Canadian consumer acquisition and/or knowledge of the country of origin of products at the time of purchase. Consumer knowledge of the country of origin of purchased products was tested as purchasers left the cash register. If the purchaser knew the country of origin of the product just purchased, they were further questioned to discover the role such knowledge might have played in their choice between alternatives. More than 93 per cent of 1,248 purchasers intercepted at the cash register had not acquired while shopping, or did not know from prior experience, the country of origin of a product they had just purchased. Of the 91 (6.5 per cent) who had acquired or knew the country of origin of a product they had just purchased, only 27 (2.2 per cent of the total) indicated that their knowledge of the product's country of origin possibly might have played a role in their product choice. These findings reveal that the country of origin of products is not an important attribute in the choice processes of the great majority of North American consumers. Confirmation of these findings by replication with less obtrusive and more externally valid measures of consumer acquisition and use of product information prior to purchase is needed.

Research has shown that stuttering may be attenuated by a variety of response-contingent consequences. To date, however, few attempts have been made to develop comprehensive clinical procedures based on the operant manipulation of stuttering. The present research examined the efficacy of self-initiated response-contingent time-out from speaking in two exeperiments involving a single subject. Multiple baseline designs were used in which the subject's speech was monitored in a variety of laboratory and community settings. In Experiment 1, the time-out procedure produced reliable reductions in disfluency across all observational settings. Experiment 2 combined a response-cost contingency with time-out in an attempt to increase the reliability with which the subject timed himself out, and to increase further the effectiveness of the procedure. Increases in reliability were produced, and the associated improvements in fluency were maintained at 6- and 12-months' follow-up.  相似文献

Behavioral momentum theory (BMT) provides a theoretical and methodological framework for understanding how differentially maintained operant responding resists disruption. A common way to test operant resistance involves contingencies with suppressive effects, such as extinction or prefeeding. Other contingencies with known suppressive effects, such as response-cost procedures arranged as point-loss or increases in response force, remain untested as disruptive events within the BMT framework. In the present set of three experiments, responding of humans was maintained by point accumulation programmed according to a multiple variable-interval (VI) VI schedule with different reinforcement rates in either of two components. Subsequently, subtracting a point following each response (Experiment 1) or increasing the force required for the response to be registered (Experiments 2 and 3 decreased response rates, but responding was less disrupted in the component associated with the higher reinforcement rate. The point-loss contingency and increased response force similarly affected response rates by suppressing responding and human persistence, replicating previous findings with humans and nonhuman animals when other types of disruptive events (e.g., extinction and prefeeding) were investigated. The present findings moreover extend the generality of the effects of reinforcement rate on persistence, and thus BMT, extending the analysis of resistance to two well-known manipulations used to reduce responding in the experimental analysis of behavior.  相似文献

We evaluated the effect of posting caloric information on food purchases at a cafeteria. Purchases of more than 14,300 entrees, vegetables, and salads by 6,970 customers were unobtrusively monitored via the cash register inventory control system during 15 evening observations. A quasi-multiple-baseline design across food groups was used to test the additive effect of labeling the three lowest caloric choices for vegetables, salads, and entrees. A linear logit analysis confirmed that labeling increased the probability of low calorie selections for vegetables and salads, but not for entrees. Observations of meals purchased by a subsample of 413 customers indicated labeling did not change the total caloric content of meals. The number of customers and total sales per evening were unaffected by the labeling intervention. The results suggest that manipulating environmental cues may be an effective method for changing food purchases in a cafeteria, but labeling individual items may not be the best way to decrease total calories purchased.  相似文献

The present study examined the effects of one component of overcorrection—verbal reprimands—and compared them with the effects of the entire overcorrection procedure. Generalization and maintenance of effects were also evaluated. A combined reversal and multiple-baseline experimental design was used to evaluate the effect of the various contingencies on the inappropriate searching behavior of a severely and profoundly mentally retarded adult living in a group home. Searching was defined as carefully and thoroughly touching floors, sofas, cabinets, etc. Data were collected by group-home personnel during three separate observation periods each day of the 115-day study: before breakfast, after breakfast, and after dinner. Observers also served as experimenters. Following an initial baseline phase, verbal reprimands followed searching behavior during two daily experimental periods in multiple-baseline fashion. An immediate reduction of searching during experimental periods occurred with the onset of verbal reprimands. No reduction was observed in the third daily observation period, the control session. After a second baseline phase, during which searching behavior was not shown to return to the original baseline levels, overcorrection procedures (washing hands) were instituted. Overcorrection virtually eliminated inappropriate searching during both daily experimental periods. Further, the effects generalized to the daily control session. In a final experimental phase, decreased searching behavior was maintained with verbal reprimands alone.  相似文献

This study compared four treatment approaches to cigarette smoking: (1) a nicotine fading procedure, in which subjects changed their cigarette brands each week to ones containing progressively less nicotine and tar; (2) a self-monitoring procedure in which subjects plotted their daily intake of nicotine and tar; (3) a combined nicotine fading/self-monitoring procedure; and (4) a slightly modified American Cancer Society Stop Smoking Program. Thirty-eight habitual smokers were assigned to one of the treatment groups. The study had two goals: (1) to achieve a clinically significant percentage of abstinence, and (2) to reduce the nonabstainers' smoking to a “safer” level by having them smoke low tar and nicotine cigarettes. The 18-month followup results showed that the nicotine fading/self-monitoring group was the most successful: 40 per cent were abstinent and all who had not quit were smoking cigarettes lower in tar and nicotine than their baseline brands. Half the nonabstainers had decreased their rate of smoking relative to baseline while the other half had increased. Furthermore, the fading/self-monitoring group achieved the largest reductions from baseline in daily nicotine and tar intake (61% and 70% respectively). The results suggest that the study's goals were achieved and that the nonaversive combined procedure could be used to treat not only habitual smokers but also smokers with severe cardiovascular and respiratory problems, because it does not have some of the inherent limitations of the successful aversive smoking cessation procedures.  相似文献

In two experiments a multiple-response repertoire of four free-operant responses was developed with university students as subjects using monetary gain as reinforcement. Following baseline, one of the responses was reduced either by making monetary loss contingent upon it (response cost) or by removing it from the repertoire (response restriction). In Experiment 1 a multielement baseline design was employed in which baseline and restriction or response-cost contingencies alternated semirandomly every 3 minutes. In Experiment 2 a reversal design was employed (i.e., baseline, restriction or response cost, then baseline), and each response required a different amount of effort. Both experiments had the following results: (a) The target response decreased substantially; (b) most nontarget responses increased, and the rest remained near their baseline levels; and (c) no support was found for Dunham's hierarchical, most frequent follower, or greatest temporal similarity rules. For several subjects, the least probable responses during baseline increased most, and the most probable responses increased least. Furthermore, in Experiment 2, responses with the lowest frequency of reinforcement increased most (for all 7 subjects), and those with the greatest frequency of reinforcement increased least (for 5 subjects).  相似文献

Prior research has indicated that frequent feedback could reduce residential electricity consumption by 10% to 15%. However, because feedback was primarily given in written form, this procedure might not be practical. The present study evaluated a potentially more practical feedback procedure during peak-use periods with high electricity consuming households. The study was conducted during the winter in an upper-middle class neighborhood of almost identical, all-electric townhouses (N = 71) that averaged about 170 KWH per day per household for a monthly bill of over $200. Twelve households received daily written feedback. Sixteen households (self-monitoring) were taught to read their outdoor electricity meter and to record KWH used every day. A comparison group was composed of 14 households that had volunteered to participate and 29 others that had only given permission to have their meters read. During a 1-month period that the procedures were in effect, the feedback group reduced consumption by 13% and the self-monitoring group by about 7%. These reductions, relative to the comparison group, were maintained during an early spring 1-month follow-up period and, to a lesser extent, during a 6-week warm spring period. Self-monitoring participants were highly reliable and persistent meter readers. Reductions in electricity use were reported by households to be largely attributable to lowering of the heat thermostat, and large monetary and KWH savings were found. Techniques to make self-monitoring cost-effective important components of the self-monitoring procedure, methods to apply self-monitoring more broadly, and plans to combine behavioral procedures with physical technology are discussed.  相似文献

This study used 1 longitudinal and 2 cross-seconal population surveys to compare stability of low-rate daily smokers (less than 5 cigarettes per day) with other daily smokers and occasional smokers. Few low-rate smokers maintained consumption level; 36% retained smoking status after 20 months, compared with 82% and 44% for regular daily and occasional smokers, respectively. In a dynamic process, established smokers quit smoking and/or modified (decreased or increased) consumption. Low-rate and occasional smokers quit at higher rates than regular daily smokers (odds ratios 3:1) but were replenished by new members, many converted from regular daily smoker. The overall trend is an increasing proportion of low-consumption smokers while smoking prevalence declines. The dynamic process has implications for tobacco control efforts and for addiction theory.  相似文献

Four parents enrolled in a Responsive Teaching class carried out experiments using procedures they had devised for alleviating their children's problem behaviors. The techniques used involved different types of reinforcement, extinction, and punishment. One parent increased the frequency of the wearing of an orthodontic device during five daily time checks by making an immediate monetary payoff contingent on wearing the device. A second parent increased the number of points earned for doing daily household tasks by providing back-ups for which the points could be exchanged. The parents of a 4-yr-old boy decreased the frequency of whines, cries, and complaints by removing social attention when such behavior occurred. A mother decreased the duration of time it took for her 5-yr-old daughter to get dressed by making permission to watch television contingent on dressing within 30 min of the time she got up in the morning. Brief reversals of contingencies were used to show causal relationships between the procedures used and the changes in behavior. Checks on the reliability of measurement were made by persons present in the home.  相似文献

Treatment acceptability refers to individuals' judgments as to whether psychological treatment procedures are appropriate, fair, and reasonable for a given problem. In the present two-experiment study, experienced teachers' ratings of acceptability for positive (i.e., praise, home-based reinforcement, and token economy) and reductive (i.e., ignoring, response-cost lottery, and seclusion time-out) behavioral interventions were investigated. Using the Intervention Rating Profile (IRP) and a case study methodology to manipulate variables of intervention complexity and problem behavior severity, it was established that (a) teachers' acceptability ratings of both positive and reductive interventions varied with the severity of a target behavior, (b) the complexity of an intervention influenced teachers' ratings of acceptability, less complex or time-consuming interventions being rated generally more acceptable, and (c) mean acceptability ratings were significantly more favorable for positive than reductive treatments. These findings are discussed in the context of previous acceptability research and future investigations.  相似文献

This study examined the effects of a group cognitive behavioral intervention on senior school students affected by the Hiroshima heavy rain disaster and investigated the effects of reducing depression by enhancing resilience. A total of 229 second-grade senior school students affected by the Hiroshima heavy rain disaster participated in the study. The intervention was performed in the following order: psychological education on daily stress, problem-solving training for daily stress, psychological education on traumatic reactions derived from traumatic experiences, and instruction on the merits of utilizing information acquired from the intervention in daily life. The results showed that the high-depression group's depression score was reduced by the intervention. Resilience score was increased both in the high- and low-depression groups as a result of the intervention. Therefore, the intervention program used in this study was proven effective in reducing depression and improving resilience. Prospectively, strategies for psychological support during and after large-scale disasters should be established by applying the findings obtained in this research.  相似文献

A rapid method of eliminating stuttering by a regulated breathing approach   总被引:1,自引:0,他引:1  
The Habit Reversal Procedure for eliminating nervous habits was applied to the problem of stuttering. In the new procedure the speaker interrupted his speech at moments of actual or anticipated stuttering and at natural pause points, and resumed speaking immediately after breathing deeply during the pause. In addition to this regularized pausing and breathing, the program included other factors such as formulation of one's thoughts prior to speaking, identification of stutter-prone situations, identification of mannerisms associated with stuttering, speaking for short durations when tense or nervous, daily breathing exercises, relaxation procedures for anxiety, immediate display of improved speaking, and enlisting family support for progress. Fourteen stutterers were given training in the program during a single counseling session of about two hours duration. The next day, the average number of stuttering episodes decreased by 94 per cent, by 97 per cent at the end of one month, and by 99 per cent during the extended follow-up. Each of the clients was improved by at least 93 per cent. The new procedure appears to be more rapid and effective than alternative procedures.  相似文献

An experimental analysis of the cost of food in a closed economy.   总被引:6,自引:5,他引:1       下载免费PDF全文
Rats lived in individual chambers in which the only food available was delivered for lever pressing. During Stage I, a fixed number of presses was required for each food pellet. As this fixed ratio of presses per food pellet was increased daily, a rat's daily intake of food was reduced. During Stage II, the cost of a food pellet was increased by replacing each fixed ratio with its interval equivalent. Each interval was a rat's mean time between the first press of a ratio and the delivery of a pellet during Stage I. During Stage II, only two presses were every required for a food pellet: The first press initiated a delay and the second activated the pellet dispenser after that delay elapsed. Food intakes for the series of fixed ratios and a rat's series of delay equivalents were very similar when plotted as a function of delay, but not when plotted as a function of presses per pellet. Consequently, the fixed ratio reduced food intake because larger ratios increased delay to food from the first press of a ratio. Observations and an analysis of interresponse times further revealed that as the fixed ratio increased, and local as well as overall rate of food intake decreased, lever pressing became more stereotyped. Because this increased stereotypy resulted in greatly increased rates of lever pressing, delay to food was minimized, and perhaps more importantly, so too was the reduction of a rat's baseline daily intake.  相似文献
