Results of the phonemic identification task for a representative participant. Responses to the 200 stimuli, each one for a specific value of voice onset time (along the horizontal axis) are shown as gray dots around 0.0 (for /da/ responses) and around 1.0 (for /ta/ responses). Vertical jitter has been added for the sake of clarity. The gray curve is the theoretical psychometric response fitted to the data. Choices of stimuli #1, #2, #3, #4, and #5, corresponding to 0%, 5%, 50%, 95% and 100% of /ta/ responses, respectively, are shown by colored dots on the psychometric curve. The VOT values for the stimuli are indicated in the horizontal axis
