Some individuals with intellectual disabilities do not respond to praise as a reinforcer, which may limit their ability to learn. We evaluated 2 procedures (stimulus pairing and response-stimulus pairing), both of which involved pairing previously neutral praise statements with preferred edible items, to determine their usefulness in establishing…

Students with or at-risk for emotional disturbance (ED) frequently receive interventions that include a direct manipulation of consequences. The ability of educators to identify reinforcing stimuli that may function as powerful consequences determines the success of reinforcement-based strategies. Choice-based stimulus preference assessments…

Background: Fear of medical procedures in general and needles in particular can be a difficult clinical challenge to providing effective health care for individuals with intellectual and developmental disabilities. Methods: A changing criterion design was used to examine graduated exposure treatment for blood-injury-injection phobia in an adult…

Highly preferred stimuli were identified via two preference assessments (based on Fisher et al., 1992), the second of which included stimuli that were ranked low in the initial preference assessment. Following the preference assessments, a subset of stimuli was evaluated as reinforcers in single- and concurrent-operant arrangements. In general,…

Brief experimental analysis (BEA) is a useful tool for quickly evaluating intervention strategies for individuals with academic deficits and minor behavior problems. However, there is a lack of research investigating BEA for intervention strategies with individuals who emit severe problem behavior to avoid academic demands. For the current study,…

Five individuals with autism or other developmental disabilities participated in paired-stimulus preference assessments during repeated baseline probes. All subjects initially showed a pronounced bias by typically selecting the stimulus placed in either the left or right position. Biased responding for 3 subjects was eliminated when training…

Background: Behavioural interventions conceptualise self-injurious behaviour (SIB) as developing from early repetitive behaviours through acquisition of homeostatic functions in regulating stimulation and subsequent shaping into SIB through socially mediated or automatic operant reinforcement. Despite high success rates, such interventions rarely…

Research has shown that variability may be an operant dimension of behavior. One method of reinforcing response variability is to use a lag schedule of reinforcement (Page & Neuringer, 1985). Several studies have shown that a Lag 1 schedule is effective in increasing variable responding with human participants (e.g., Esch, Esch, & Love, 2009; Lee,…

We evaluated a multiple schedule in which the extinction (S-) components were signaled overtly by a black lanyard and the reinforcement (S+) components were not correlated with any programmed stimuli in developing stimulus control over the high-rate social-approach responses of an adult with mental retardation. Responding was consistently low in…

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…

We conducted three experiments to reproduce and extend Perone and Courtney's (1992) study of pausing at the beginning of fixed-ratio schedules. In a multiple schedule with unequal amounts of food across two components, they found that pigeons paused longest in the component associated with the smaller amount of food (the lean component), but only…

Training context can influence resistance to disruption under differing reinforcement schedules. With nonhumans, when relatively lean and rich reinforcement schedules are experienced in the context of a multiple schedule, greater resistance is found in the rich than the lean component, as described by behavioral momentum theory. By contrast, when…

Three adults with intellectual disabilities participated to investigate the effects of reinforcer deprivation on choice responding. The experimenter identified the most preferred audio-visual (A-V) stimulus and the least preferred visual-only stimulus for each participant. Participants did not have access to the A-V stimulus for 5 min, 5 and 24 h.…

Determining effective reinforcers for individuals with disabilities is imperative for skill acquisition and behavior reduction. Various methodologies exist to determine reinforcer preference, and past research has shown that results vary across different techniques. The purpose of the current study was to assess which presentation methods were…

A functional analysis suggested that rumination exhibited by an adult with autism was maintained by automatic reinforcement. Next, a preference assessment with three flavor sprays (i.e., flavored sprays used by dieters) showed that apple pie spray was most preferred. Finally, the effects of fixed-time delivery of the apple pie spray on levels of…
