This study assessed the effects of dashboard stickers and signature sheets on safety belt use among occupants of state-owned vehicles in three Florida agencies. The stickers and signature sheets contained information regarding a regulation requiring safety belt use and a consequence of a 25% reduction in benefits for noncompliance if the driver were to become involved in an accident. Safety belt use significantly increased during the intervention phase in all three agencies and maintained variable but high levels for 5 months. In Agency 1 and Agency 2 (stickers plus signature sheets) safety belt use increased from averages of 10.8% and 9.4% during baseline to 57.4% and 47.0%, respectively, during intervention. In Agency 3 (stickers only) the rates of safety belt use averaged 9.7% during baseline and 38.0% during intervention. Some increases in private vehicle use were observed. A substantial reduction in workers'' compensation claim costs was shown for the target agencies with some reductions also shown in the nontarget agencies. 相似文献

An armed robbery alarm system was implemented in 48 different stores in two separate geographical areas for 6 months and 12 months, respectively. The alarms were placed in the two separate areas at different times and all alarms were eventually removed. Thus, multiple baseline and reversal strategies were used to evaluate program impact. A device planted in a cash drawer was triggered whenever “bait” money was removed from the drawer sending an alarm signal directly to police cars and headquarters. Onscene apprehensions of armed robbers within target stores were greatly increased even though the armed robbery systems did not deter robbery incidents nor influence the court disposition of the cases. There was also no crime deterrence, crime displacement, or increased apprehensions in either the immediate neighborhoods of target stores or on a city-wide basis. The cost effectiveness of the program was calculated to be poor even though the program is being maintained because of the absence of an alternative robbery apprehension technology. 相似文献

A naturally occurring experiment, in which direct supervision of a token economy in a penal system was removed and re-instated, is reported. A retrospective analysis revealed that in the absence of close supervision the use of response cost rose dramatically, both in terms of categories of behaviors for which response costs were levied and in the frequency of their use. The return of direct supervision led to a decreased use and an end to the growth of categories of behaviors punished. 相似文献

An experimental analysis of electricity conservation procedures 总被引:2,自引:0,他引:2
Daily electricity consumption of four families was recorded for 106 days. A reversal design, consisting of various experimental conditions interspersed between repeated baseline conditions, was used. During experimental conditions, daily prompts (written conservation slogans attached to front doors) and/or daily feedback (daily kilowatts consumed and daily cost information) were in effect. Maximum consumption occurred during the initial baseline; minimum consumption occurred during different experimental conditions for different families. The mean decrease from the maximum to the minimum for all families was 35%. Reversals in consumption were demonstrated in three families, although successive baselines tended to decrease. No clear differences in effectiveness between prompting and feedback conditions were apparent. The procedures used resulted in considerable dollar savings for the families. 相似文献

The effect of a group response-cost procedure (accompanied by verbal and written instruction) designed to decrease cash shortages in a small business was evaluated with a reversal design. When cash shortages were subtracted from the six employees' salaries on days in which the shortage exceeded 1% of total daily sales, the magnitude of daily shortages sharply decreased. This response-cost contingency was used only three times throughout the study, with a maximum cost of $8.70 per subject over the 41-day period. The efficacy of the procedures may be due to either increased precision in change calculations, a decreased frequency of stealing from the cash register, increased shortchanging of customers, and/or increased incidents of register under-ringing. Ethical questions relative to the utilization of group punishment procedures are raised, and it was concluded that the procedures used were more humane than commonly used alternatives. 相似文献

We investigated the effects of proximity of containers on pounds of office paper recycled and not recycled by 25 employees. During a memo and central container condition, one container for recyclable paper was provided; in a memo and local container condition, desktop recycling bins, announced by memo, were successively introduced across administrative, office, and instructional settings using a multiple baseline design. Only 28% of paper was recycled in the central container condition, but when recycling containers were placed in close proximity to participants, 85% to 94% of all recyclable paper was recycled. Follow-up assessments, conducted 1, 2, 3, and 7 months after all settings received local recycling containers, showed that 84% to 98% of paper was recycled. Providing desktop recycling containers was a cost-effective procedure with long-term maintenance and program survival. 相似文献

The concepts of behavioral economics have proven to be useful for understanding the environmental control of overall levels of responding for a variety of commodities, including reinforcement by drug self-administration. These general concepts have implications for the assessment of abuse liability and drug abuse intervention and the formulation of public policy on drug abuse. An essential requirement is the ability to compare the demand for different drugs directly in order to assess relative abuse liability, and to compare demand for the same drug under different environmental and biological interventions to assess their ability to reduce demand. Until now, such comparisons were hampered by the confounding effect of varying drug doses and potencies that prevent quantitative comparisons of demand elasticity--sensitivity of consumption and responding to the constraint of price (effort). In this paper we describe a procedure to normalize demand-curve analysis that permits dose- and potency-independent comparisons of demand across drugs. The procedure is shown to be effective for comparing drug demand within and across the drug classes. The technique permits a quantitative ordering of demand that is consistent with the peak levels of responding maintained by the drugs. The same technique is generalized for the comparison of other types of reinforcers under different biological conditions. 相似文献

Foraging involves the expenditure of both time and effort in the acquisition of food; animals typically modify their meal patterns so as to reduce these expenditures or costs. The contribution of time, as compared with effort, to the overall cost perceived by an animal is not known. We investigated the effect of foraging time as a cost independent of effort by measuring the meal patterns of rats living in a laboratory foraging simulation in which they earned all their daily intake. They pressed a bar once to initiate an interval (procurement interval) leading to the presentation of a large cup of food from which they could eat a meal of any size. As the length of the interval increased from 1 s to 46 hr, meal frequency decreased regularly. Meal size increased in a compensatory fashion, and total daily intake was conserved through an interval of 23 hr. The changes in meal frequency occurred because of changes in the rat's latency to bar press after each meal. The functions relating meal frequency and size to the procurement interval were of the same shape as those seen when cost is the completion of a bar-press requirement, which entails the expenditure of both effort and time. When the bar-press requirement was increased to 10, meal frequency was reduced, but time and effort did not appear to simply add together in the rat's perception of cost. These data reveal that time is preceived to be a cost by rats foraging in this laboratory environment. These results suggest that the time parameters of foraging are different from those of consumption. 相似文献

The participant in this study was a boy with a long history of self-injurious face slapping. Following a functional analysis indicating that face slapping was maintained by sensory consequences, the participant was given soft wrist weights to wear for progressively longer periods. Data on the frequency of face slapping were collected 5 min before the weights were put on, while the weights were on, and 5 min after the weights were removed. At all other times a protective helmet was placed on the participant's head for 30 min contingent on face slaps. When weights were worn for 30 min each day, face slapping decreased during 5-min observation periods before and after wearing the weights. The use of protective headgear was eliminated by the end of the study. Face slapping did not occur during a follow-up check conducted 5 months after completion of the study. 相似文献
