Rapid adaptation and auditory localizer experimental paradigms. (A) The slow clustered acquisition paradigm used in the auditory localizer scan. Each trial was 9 s long with 1.5 s of volume acquisition and 7.5 s of silence. During the silent period, the subject heard four sounds from one of five stimulus classes and performed a 1-back task. (B) The rapid clustered acquisition paradigm used for the RA scans (Chevillet et al., 2013; Jiang et al., 2018). Each trial was 3.36 s long with 1.68 s of volume acquisition. During the silent period, two spoken words were played to the subject with a 50 ms interstimulus interval. The first word acted as a prime and the second word the target. The experimental paradigms for (C) real words and (D) pseudowords. The prime was followed by a target word that was either the same word (SAME), a word that differed from the target by one phoneme (1PH), or a word that shared no phonemes with the target (DIFF). Furthermore, subjects were presented with silence trials that served as an explicit baseline. During the task, subjects were asked to attend to all the words and respond when they heard the oddball stimulus (RW or PW containing the rhyme “-ox,” e.g., “socks”) in either the prime or target position.
