Reinforcement process may underlie decisions frequently found in organizations to escalate investments of time, money and other resources in strategies (e.g., product development, capital investment, plant expansion) that do not result in immediate reinforces. Whereas cognitive biases have been proffered in previous explanations, the present analysis suggested that this persistence is a form of resistance to extinction arising from experiences with past investments that were variably reinforced. This explanation was examined in two experiments by varying the pattern of returns and losses subjects experienced for investment decisions prior to experiencing a series losses. Consistent with the proposed explanation, two conditions resulted in higher levels of recommitment during continuous losses: (a) training using a variable schedule of partial reinforcement, and (b) no training on the task. Results indicate that behavior analysis can be used to understand and control situations in organizations that are prone to escalation, such as investments in the research and development of new product lines and extensions of further loans to customers. 相似文献

Three individuals with developmental disabilities participated in a study of the treatment of self-injurious behavior (SIB) maintained by negative reinforcement (escape from educational tasks). Treatment was implemented in a multiple baseline design across subjects, in which two treatments were compared in a multielement format. Both treatment conditions included an escape-extinction component in which SIB no longer produced escape. One of the conditions also included a fading component in which the frequency of instructions was initially reduced to zero and then was gradually faded back in across sessions until the instructional rate matched that of the original baseline. Results indicated that extinction alone reduced SIB to the end-of-treatment criterion in fewer sessions than did extinction plus fading for all 3 subjects. For 2 of the 3 subjects, however, there was an initial increase in the frequency of SIB at the outset of treatment with extinction (an extinction burst) that was not observed when extinction was combined with the fading component. 相似文献

Previous research has shown that self-injurious behavior (SIB) maintained by positive reinforcement may be reduced under differential-reinforcement-of-other-behavior (DRO) contingencies. In this study, we conducted an analysis of the reinforcement and extinction components of DRO while treating the self-injury of 3 women with developmental disabilities. A functional analysis revealed that each subject's SIB was maintained by positive reinforcement in the form of attention. Subsequent reinforcer assessments identified preferred and nonpreferred stimuli for later use in conjunction with DRO. Results showed high rates of SIB for all 3 subjects during baseline, which persisted when DRO was implemented without the relevant extinction component (withholding of attention for SIB) for 2 of the subjects. Low rates of SIB were observed for all subjects when DRO plus extinction was implemented or when extinction was implemented alone, suggesting that extinction may be a critical component of DRO schedules. 相似文献

Lever attacking and pressing as a function of conditioning and extinguishing a lever-press avoidance response in rats 下载免费PDF全文
Six experimental rats were conditioned to press one of two available levers to avoid shock. The levers registered bites as well as presses. For four of these rats, shock was contingent on lever bites when a specified time period had elapsed after the previous shock. An extinction period, in which only periodic noncontingent shocks were presented, followed avoidance training. Six yoked-control rats received the same sequence of shocks as did the corresponding experimental rats in both the conditioning and extinction phases. All six experimental rats repeatedly bit the avoidance lever. Four bit it more than the nonavoidance lever during conditioning, and five bit it more during extinction. Five of the six experimental rats consistently bit the levers many more times during each session than did their respective control rats, suggesting that avoidance conditioning facilitated lever biting. Rates of lever biting and pressing by all of the experimental rats and by some of the control rats were highest immediately following shock throughout both phases. During later portions of the intervals following shock, characteristic effects of conditioning and extinction were observed. This finding suggests that extinction of avoidance behavior by unavoidable shock presentations can be demonstrated more readily when shock-elicited responding is extricated from the data. 相似文献

A twin-signal device that provides both escape and avoidance conditioning in enuresis control is described involving a procedure documented by two case studies. In addition, a technique of fading as an adjunct to the process is utilized with one subject. The results indicate that a combination of operant and respondent conditioning involving escape and avoidance training may be an improvement over the more traditional conditioning procedure. 相似文献

We examined the effects of noncontingent and contingent protective equipment as treatment for self-injurious hand mouthing exhibited by 2 individuals with profound mental retardation. Results of a functional analysis assessment revealed that neither subject's self-injury was maintained by social reinforcement: One subject's self-injury was cyclical in nature; the other's occurred during all assessment conditions but most frequently when left alone. In the noncontingent-equipment condition, oven mitts were placed on the individual's hands at the beginning of a session and remained on throughout. In the contingent-equipment condition, the mitts were briefly placed on the individual's hands following occurrences of hand mouthing. For 1 subject, noncontingent mitts produced a large decrease in the rate of hand mouthing and contingent mitts produced similar results following a return to baseline. Hand mouthing was also reduced in the 2nd subject, but this individual was exposed only to the contingent-equipment condition (i.e., there was no prior history with the noncontingent-equipment condition). These results suggest either a punishment or a time-out interpretation rather than an extinction interpretation to account for the behavior-reducing effects of contingent protective equipment on self-injury. 相似文献

恐惧消退是指反复呈现条件刺激(conditioned stimulus, CS)而不匹配无条件刺激(unconditioned stimulus, US),从而消除个体已有的恐惧反应。应激激素,如去甲肾上腺素(Norepinephrine,NE)和糖皮质激素(Glucocorticoids,GCs),可通过影响腹内侧前额叶、杏仁核和海马等与消退学习有关的神经回路的活动,调节恐惧消退学习效果。NE和GCs对恐惧消退学习的调节作用受激素水平与激素用药时间的影响,且其调节效果存在性别差异。未来研究需进一步探索应激激素如何影响恐惧消退学习效果,并思考如何利用其影响效果促进暴露疗法疗效。 相似文献

In two experiments, pigeons were exposed to a three‐phase resurgence procedure (train Response A; extinguish Response A and train Response B; extinguish Response B). In the first experiment, the stimuli associated with phases were different, resulting in a resurgence procedure combined with an ABC renewal procedure. Presenting the novel stimulus, C, during extinction of both responses in the third phase resulted in minimal resurgence. Subsequently, substituting the original training Stimulus A for Stimulus C resulted in resurgence with all pigeons. In the second experiment, resurgence with the same stimuli present in all three phases of the resurgence procedure (AAA) was compared concurrently with a resurgence procedure in which the ABC renewal procedure used in Experiment 1 was superimposed. Substantially more resurgence occurred with the AAA procedure compared to the ABC procedure. Although ABC renewal in combination with the resurgence procedure generated some resurgence, such recurrent responding was attenuated relative to that observed when the stimulus conditions were constant across phases. Combined with earlier research showing the enhancing effects of combining resurgence and ABA renewal procedures, the present results elaborate on how stimuli correlated with certain behavioral histories affect the course of operant resurgence. 相似文献

Does preference rank predict substitution for the reinforcer for problem behavior? a behavioral economic analysis 下载免费PDF全文
Michelle A. Frank‐Crawford Mariana I. Castillo Iser G. DeLeon 《Journal of applied behavior analysis》2018,51(2):276-282
Predictions made under low response requirements inherent in most preference assessments (PAs) do not guarantee the utility of stimuli in treatments. We examined whether PA rank would predict how well stimuli supported compliance for children with escape‐maintained problem behavior by examining the relation between PA rank and demand elasticity across five fixed‐ratio values. Three patterns were observed: All stimuli were selected equally across values, higher ranked stimuli were selected more at higher values, and something other than the highest ranked stimulus was selected more at higher values (i.e., mixed correspondence). 相似文献

In behavioral economics terms, response allocation is viewed as an exchange between the price of and the demand for reinforcers associated with various responses. In this study, behavioral economics principles were used to develop and evaluate a treatment package that reduced destructive behavior to zero while communication and compliance were increased. 相似文献
