Research on stimulus-stimulus pairing to induce novel vocalizations in nonverbal children has typically employed response-independent pairing (RIP) procedures to condition speech sounds as reinforcers. The purpose of the present study was to evaluate the effects of a response-contingent pairing (RCP) procedure on the vocalizations of three…

This study examined how the amount of effort required to produce a reinforcer influenced subsequent preference for, and strength of, that reinforcer in 7 individuals with intellectual disabilities. Preference assessments identified four moderately preferred stimuli for each participant, and progressive-ratio (PR) analyses indexed reinforcer…

Time-out is an effective child deceleration technique. The Time-Out Grid is a simple heuristic tool illustrating the fundamental feature of an effective time-out intervention and subsequently guides those involved in the problem analysis and program evaluation phases of consultation. Provides specific procedural recommendations for classroom…

Both studies found significant positive "side effects" of punishment in terms of increased play and social behavior as well as increased performance of…
