A combination of synchronous reinforcement and verbal prompts (automatically delivered through portable
technology) was used to promote performance fluency in a person with profound intellectual disability and blindness.
Performance fluency was measured on indoor walking and task engagement. Data indicated that the combination of
reinforcement (favourite songs) and prompts was quite effective; it increased the distance covered per minute and the
number of objects disassembled per minute. Implications of the findings are discussed.
