Emergence of Rule Following and Tact-Intraverbal Responses after Multiple Exemplar Instruction

ABSTRACT:

The objective of this study was to verify the effects of teaching with Multiple Exemplar Instruction (MEI) involving, in each trial, the response of following a tact-intraverbal instruction to a spatial relation (for example, left) in the emergence of new responses and for the spatial relation not directly taught (for example, right) for body parts (arm, ear, hand, leg). Additionally, generalization was tested by means of objects that were not used in teaching. Participants were four children and adolescents diagnosed with Autism Spectrum Disorder (ASD) and intellectual disability, aged seven to fourteen. The sequence of the procedure was: tests of rule following and tact-intraverbal in baseline; teaching with MEI for a spatial relation; final test of rule following and tact-intraverbal for the spatial relation not directly taught; generalization test. Multiple probes design coupled with multiple baseline across participants design was used. The results suggest that teaching with MEI was sufficient for the emergence of responses not directly taught and generalization. It could be inferred that the procedure was effective and efficient, as it generated the emergence of responses not directly taught and the learning took place in a few blocks.
