Token economies are one of the most commonly used behavior-analytic interventions. Despite literature supporting the use of tokens as tools for behavior change, little is known about the efficacy of tokens compared to that of the items for which they are exchanged. Results of previous research comparing the reinforcing efficacy of tokens and primary reinforcers have shown that both produce similar effects on responding. However, published findings have been confounded given the inclusion of primary reinforcers in the token-reinforcer test conditions. In this study, we established novel tokens as reinforcers. We then conducted a conditioned-reinforcer assessment using a tandem control to ensure that the tokens functioned as reinforcers. We used progressive-ratio schedules to compare the reinforcing efficacy of the tokens to high- and low-preference edibles that were also used as backup reinforcers. For both participants, we found that high-preference primary reinforcers maintained higher response frequencies than did tokens. 相似文献

Annually, thousands of infant deaths are classified as sudden unexpected infant deaths (SUIDs). In an effort to reduce the risk of SUIDs, the American Academy of Pediatrics has made a number of recommendations to educate caregivers, childcare providers, and healthcare professionals on safe infant sleep practices. The purpose of the current study was to extend the literature on safe infant sleep practices by teaching caregivers to arrange safe infant sleep environments using a mannequin and common infant items. We partnered with community-based agencies to evaluate the effectiveness of behavioral skills training delivered in a single training session as part of the ongoing pre- or postnatal care these agencies provided. Following training, all participants demonstrated a substantial change in responding and returned favorable social validity ratings. We discuss these outcomes in light of previous studies, limitations, and future directions. 相似文献

In Rawlsian political philosophy, “basic liberties” are rights subject to a high degree of protection, such that they cannot easily be overridden for concerns of stability, efficiency, or social justice. For Rawls, something qualifies as a basic liberty if and only if bears the right relationship to our “two moral powers”: a capacity to form a sense of the good life and a capacity for a sense of justice. However, which rights are basic liberties is subject to frequent ideological debate, which Rawlsian libertarians and Rawlsian socialists arguing that Rawls's own view is mistaken or incomplete. I argue that problem is that Moral Powers Test does not quite work. Only a small amount of liberty—not enough to qualify a society as liberal—can clearly be shown to pass the Moral Powers Test. One might attempt to rescue the Moral Powers Test by relaxing or modifying its requirements, but, I will argue, there appears to be no unproblematic and nonquestion‐begging way to do so. The Moral Powers Test must be abandoned or, at least, requires some unknown but radical revision or require supplements from outside Rawls's own theory. 相似文献

Chronic Fatigue Syndrome (CFS) is an illness that involves severe, prolonged fatigue as well as neurological, immunological, and endocrinological system pathology. Because the pathogenesis of CFS has yet to be determined, case definitions have relied on clinical observation in classifying signs and symptoms for diagnosis. In an attempt to address various criticisms and inconsistencies in diagnostic criteria, there have been several revisions of the CFS case definition. The current investigation examined the differences between 1988 and 1994 definitions as well as participants who had a psychiatric explanation for their fatigue. Dependent measures included psychiatric comorbidity, symptom frequency, and functional impairment. The 1988 criteria, compared to the 1994 criteria, appeared to select a group of participants with more symptomatology and functional impairment, but these groups did not significantly differ in psychiatric comorbidity. Implications of these findings are discussed. 相似文献

In this paper it is contended, against a challenging recent interpretation of Frege, that Frege should be credited with the first semi-rigorous formulation of semantic theory. It is argued that the considerations advanced against this contention suffer from two kinds of error. The first involves the attribution to Frege of a sceptical attitude towards the truth-predicate. The second involves the sort of justification which these arguments assume a classical semantic theory attempts to provide. Finally, it is shown that Frege was in fact mindful of the need for the relevant sort of justification. 相似文献

This study describes the use of sensory stimulation to reduce self-stimulatory behavior of hand mouthing by an institutionalized adult male with profound developmental disabilities. The data showed that when an extra amount of food was presented to eat at meal time, the mouthing behavior decreased quickly to an appreciably lower level. Results suggested that additional food could effectively reduce hand-mouthing behavior in a short period of time if it served a similar function—to provide preferred sensory reinforcers to the individual. An interesting phenomenon which had been observed in this study was a shift in sensory stimulatory behavior or sensory reinforcer from one form to another. While hand mouthing was decreasing, vocalization seemed to be increasing. The advantages of providing additional food as a treatment strategy are discussed with reference to other studies using response inhibition to treat hand mouthing behavior. © 1997 John Wiley & Sons, Ltd. 相似文献
