Strategies for increasing response behavior of 1- and 2-year-old children during visual reinforcement audiometry (VRA).
This study investigated strategies for increasing the number of responses that can be obtained from young children during visual reinforcement audiometry. Subjects included normal 1- and 2-yr-old children. Responses before habituation were studied as a function of age, reinforcer conditions, and test sessions. It was found that: (1) using two reinforcers led to more responses before habituation than use of a single reinforcer; (2) after habituation in test session 1 and a 10-min break, most 1-yr-olds demonstrated a minimum of five additional responses in test session 2; and (3) 2-yr-olds habituated more rapidly than 1-yr-olds.
