“…In studying children's early gestures, the primary focus of research attention has been on pointing gestures, perhaps because this gesture appears to be ubiquitous in infant development (e.g., Carpendale & Carpendale, 2010;Carpendale & Lewis, 2021;Shinn, 1900;Tomasello et al, 2007). Less attention, however, has been paid to the development of other forms of gestures, such as objectextension gestures, conventional gestures, and iconic gestures (Acredolo & Goodwyn, 1985, 1988Goldin-Meadow & Feldman, 1977;Guevara & Rodríguez, 2023). We examine the "genealogy of gestures" because we are concerned with the origins and development of various forms of gestures and how they differ and are interrelated in the process of development (see Wittgenstein, 1980b, §722, on a genealogy of psychological concepts).…”
