Habituation and Dishabituation (7C) Practice Test

In a classroom, a teacher plays a short notification chime (1 s) before starting group work each day. On the first day, students stop talking immediately when the chime sounds. After several weeks, students show little change in behavior when the chime plays and continue talking. One day, the fire alarm sounds unexpectedly during class. Later that same period, the teacher plays the usual chime and students abruptly stop talking, but over the next days they again ignore the chime. Based on this pattern, which response is most consistent with habituation and dishabituation rather than sensitization?

In a study of habituation to smartphone notifications, participants sit quietly while a standard notification sound plays every 45 seconds. Initially, participants orient toward the phone and interrupt their current activity; after repeated notifications, orienting behavior decreases. Midway through the session, the experimenter plays a different, novel ringtone once and then returns to the standard notification sound. Which behavioral outcome would most strongly support dishabituation to the standard notification sound?
