Use of a high-probability instructional sequence to increase compliance to feeding demands in the absence of escape extinction

We evaluated the effects of a high-probability (high-p) instructional sequence on the feeding-related compliance (food acceptance) of a young boy diagnosed with a feeding disorder. The high-p sequence consisted of three presentations of an empty spoon; the low-probability (low-p) instruction was the presentation of a spoon with food. Results showed that acceptance of food increased in the presence and not the absence of the high-p sequence. Data are discussed in terms of the role of high-p instructional sequences in the treatment of feeding problems.
