Part 2: Cue weighting categorization - all tasks with instructions and practice trials. During the experiment, participants complete 10 blocks of each task (phrase, focus, music, and stress), with 16 trials per block. Blocks of different cue weighting tasks are alternated in the following order: musical beats, linguistic focus, lexical stress, and phrase boundary. Prior to the tasks, participants complete two example trials per feature to familiarize themselves with the task format and the types of stimuli they will be categorizing.
