“…Starting from the notion that development means change over time, most studies use a longitudinal research design that follows the interactional practices of one or a small number of target participants over a longer or shorter time span (days, months, or years). These studies often focus on a defined social action or activity, such as the opening of a task or a storytelling (Hellermann, , ; Pekarek Doehler & Berger, ), self‐repair (Hellermann, ; Sert & Balaman, ), or practices for managing transitions between topics and activities (Kim, ; Nguyen, ; Nguyen, ). Based on longitudinal recordings of naturally occurring conversations and related micro‐level transcriptions, they track how the target participants change their practices for accomplishing the particular actions or activities over time.…”
