Reinforcing infant vocalisations through self-initiated feedback: a tool for basic research and for clinical interventions

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We introduce a method for reinforcing vocalisations
in prelinguistic infants (ages 6-7 months) without
recourse to social feedback, through a self-reinforcing
app. Study 1 presents findings that show that infants
(N = 60; n= 30 in the experimental group) respond to
the app’s reinforcement by increasing their
vocalisations. Study 2 is a randomised clinical trial
(data collection ongoing). Infants from low
socioeconomic-status families were recruited (N =
96, n = 48 in the intervention group). Families in the
intervention group use the app over 3 weeks. Infants’
are followed over 9 months until age 16 months.
Demographic data for the two groups will be presented. We predict that infants in the intervention group will be more linguistically, but not motorically, advanced than those in the control group by the end of the study. We discuss potential uses of this method for basic as well as clinical research and intervention.
