ABSTRACT
Rehearsal is a form of self-talk used to support short-term memory. Historically, the study of rehearsal development has diverged from the study of self-talk more generally. The current experiment examines whether two characteristics of self-talk (impact of task difficulty and self-talk's narrative vs. planning purpose) are also observed in rehearsal. Eighty children, ages 4-7, were tasked with remembering the three-item and six-item lists over a 15-s delay. Children's spontaneous use of fixed rehearsal (i.e., immediate repetition of a just-presented item) and cumulative rehearsal (i.e., cycling through multiple items at a time) was documented from video recordings. Four-year-olds narrated item presentations using fixed rehearsal. Six- and seven-year-olds proactively planned for recall by engaging cumulative rehearsal. Five-year-olds used both forms of rehearsal, but their frequency of cumulative rehearsal was dependent on list length. Therefore, rehearsal is susceptible to task manipulations that affect other forms of self-talk. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
