Computer-Based Video Instruction to Teach Persons with Moderate Intellectual Disabilities to Read Grocery Aisle Signs and Locate Items

The purpose of this study was to evaluate the use of computer-based video instruction to teach generalized reading of words found on grocery store aisle signs and the location of the corresponding grocery items within those aisles. A multiple probe design across three sets of words, replicated across four students with moderate intellectual disabilities, was used to evaluate the effectiveness of the computer-based video program. All training sessions occurred through simulation using the computer-based program with "life-like" video recordings of multiple examples of three grocery stores. All generalization probes, including generalized reading of target words in a novel grocery store, were assessed in actual grocery stores. Results indicated that the computer-based video program alone was successful in teaching generalized reading of aisle signs and the location of items and that students generalized responding to a novel grocery store. Results are discussed in terms of the advantages of computer-based video instruction.
