Caregiver preference did not coincide with preferred reinforcers: better results when preferences were tested, why is it important to find preferred stimuli, maybe johnny likes skittles but they may not be reinforcers. Prefferred stimuli more likely to be reinforcer; not always but more likely. Caregiver interview: asking others who know the subject, direct observation (free operant) Single item (pace procedure: test to see what item is preffered. Paired (forced choice: ask this or this between multiple times and calculate the ones with highest rate of being chosen, multiple choice wo replacement. Series of items, you pick one and interact with that one and that one goes away and you look at the rest. We conducted teacher interviews and direct assessments to identify preferences of young children in an early education setting. Small groups of teachers identified and ranked 10 items; these same 10 items were then evaluated in a paired-stimulus preference assessment (fisher et al. , 1992).
