Categorical auditory perception as a strategy for studying speech perception difficulties . Psicol. pesq. [online]. 2020, vol.14, n.spe, pp. 56-75.

This article presents a methodological study of an experimental procedure with two tasks of categorical auditory processing for speech. In the identification task, the participant hears sounds that vary in VOT duration and is asked to identify which word they correspond to. In the discrimination task, the participant must indicate whether two adjacent VOT stimuli are the same or different. The data analysis strategies to characterize the degree of categorization are presented and possibilities of using the procedure in studies are discussed.
