Abstract:
A five-up, five-down automated staircase procedure was used to explore the effects of variable starting and stopping rules as they interact with infant behavior in influencing the accuracy and efficiency of infant auditory threshold testing. Results from 146 infants were compared to results from computer simulations (see accompanying article) in order to evaluate an infant response model used in the simulations. Results indicate that the automated procedure successfully discriminated between infants with normal versus abnormal tympanograms. In addition, the model accurately predicted infant results in terms of the effects of starting and stopping rules. The model was less useful in predicting the relationship between minimum response levels and false positive rates.
