Results of an analogue functional analysis indicated that noncompliant vocal behavior exhibited by a young girl with autism was maintained by negative reinforcement. Follow-up analyses suggested that the immediate escape contingency assessed in the demand condition did nor appear to maintain the behavior. Instead, noncompliant vocal behavior…

This article presents the argument presented by the author regarding the views of Baron and Galizio (2005), which provide an accurate and very clear version of the author's arguments against the use of the positive-negative reinforcement distinction in behavior analysis. Here, the author points out few things to add to Baron and Galizio's (2005)…

In this article, the author discusses and presents seven possibilities that describe how symmetry principles are reflected in behavior analysis. First, if there are apparently no functional distinctions to be made between positive and negative reinforcement, then reinforcer effectiveness (by various measures) is invariant under a simple inversion…

The study investigates the development of English multiword negation, in particular the negation of zero marked verbs (e.g. "no sleep", "not see", "can't reach") from a usage-based perspective. The data was taken from a dense database consisting of the speech of an English-speaking child (Brian) aged 2;3-3;4 (MLU 2.05-3.1) and his mother. The…

Two studies were done in which the subjects applied punishment contingencies to themselves for smoking cigarettes. After Baseline in Experiment I, the subject set a limit of 15 cigarettes for himself. If he exceeded the level, he was to tear a dollar bill into pieces for every additional cigarette he smoked. Every five days the criterion was…

B. Rimland speaks of the risk/benefit ratio of aversives for use with autistic children, and parents comment on the concept. (SBH)

Incentive and behavior were investigated in the study focusing upon a comparison of the effects of response cost (for errors) and response reward (for correct responses) on verbal performance of mentally retarded subjects. (KW)

In a previous issue of "The Behavior Analyst," the authors discussed the ambiguities that surround the distinction between positive and negative reinforcement. Seven distinguished behavior analysts commented on their article. The authors believe that this dialogue represented a constructive step toward clarification of an important concept within…

Based in part on a PhD dissertation (Irwin) submitted to the University of Pennsylvania.

Use of tokens as positive reinforcers for correct responses in speech therapy and no consequences for incorrect responses was compared with the use of tokens contingent upon correct responses and loss of tokens for incorrect responses. (Author)

Time-out from positive reinforcement was found to have a suppressive effect when the response alternative was reinforced with the same frequency as the punished response. When the response alternative was a response for which positive reinforcement had been withdrawn, time-out was significantly preferred. (MH)

In this article, the author presents his views on Michael's (1975) and Baron and Galizio's (2005) arguments on eliminating the distinction between positive and negative reinforcement. He first discusses Michael's concept of these two types of operations and contrasts it with the notions of Baron and Galizio. The author provides the readers his own…
