... The temporal contingency of parental vocal responses (i.e., those that are close in time to the child's utterances), has been found to be important from the earliest stages of language development (Yoo et al., 2018). For example, contingent responses promote increased babbling and speech-like vocalizations in infants (Bloom et al., 1987;Elmlinger et al., 2023;Goldstein et al., 2003;Gros-Louis et al., 2014;Long et al., 2022). Moreover, the sheer number of conversational turns is predictive of children's vocabulary and phonological development, even after accounting for the number of words (Donnelly & Kidd, 2021;Gilkerson et al., 2018;Ha et al., 2022), and this factor has been linked to differences in neural processing (Romeo et al., 2021;Romeo et al., 2018) and patterns of atypical development (Warlaumont et al., 2014). ...
