TL;DR: Only the frequency of mothers' follow-prescriptives correlated significantly with a productive vocabulary measure taken at 1;10, indicating that, given joint focus, directing a 13-month-olds behaviour can have beneficial effects on subsequent vocabulary development.

TL;DR: In this article, two groups of 18-month-old infants were observed during a relatively natural play session with an adult experimenter and several toys, and a novel object associated with one of the toys was labeled a dodo by the experimenter using either an attention-following strategy (i.e., introducing the label when the infant was focused on the dodo object) or an attention switching strategy (e.g. introducing the labels when the infants were focused on an alternative object) with factors such as frequency of exposure to the object label and infant compliance equivalent across

TL;DR: Individual differences in mother's tendencies to describe aspects of the environment occupying their infant's current focus of attention were measured during interactions with their 13-month-old infants and their frequency was correlated with measures of their infants' productive lexical development.

TL;DR: A measure of the time the dyads spent in a state of vocal turn-taking predicted individual differences in the infants' subsequent performance on the contingency task, parallel the social transfer effects reported earlier.

TL;DR: 3 experiments with 3-month-old infants compared the effects of contingent and noncontingent adult-infant social interactions on subsequent infant-controlled habituation and choice tasks and found infants who experienced a prior non Contingent social interaction tended to adopt response strategies that reduced the density of stimulation during these subsequent nonsocial tasks.
