An Adaptive Sampling Procedure for Speech Perception Experiments

–Obtain a sampling resolution comparable to 6 responses per stimulus (580 responses) in a time of 30 minutes. Procedure 1. All stimuli are presented twice in random order, the listener identifies the stimuli (180 responses). 2. A logistic regression model is fitted to the response data, and the predicted probabilities of each category for each stimulus are calculated. 3. The error between the observed and predicted probabilities for each stimulus is calculated. 4. Half the stimuli are resampled (45 responses). 4.1 stochastic noise is added to the error scores 4.2 the stimuli with the highest error+noise scores are resampled 5. Steps 2 through 4 are repeated three more times.
