objectivesThe present study explored how shared reading experience influenced predictive brain signals and expressive vocabulary of 12-month-old infants.
outcomes evaluatedBrain signals and expressive vocabulary
settingParticipants were recruited through online advertisement in 2020 and the database of interested participants for the NTNU-Haskins Joint Laboratory of Brain Development and Learning.
methodsTo achieve these aims, we tested 12-month-old infants’ predictive brain signals using functional near-infrared spectroscopy (fNIRS), their parent-child shared reading experience as assessed by the StimQ-READ subscale-Infant [31, 32] translated into Chinese, and their expressive vocabulary as assessed by the Infant form of the Mandarin-Chinese Communicative Development Inventory (Taiwan) (hereafter MCDI-T) . We hypothesized that the parent-child shared reading experience would be positively correlated with the strength of the predictive brain signal and that the predictive brain signal would serve as a mediator that explains the underlying mechanism of the relation between parent-child shared reading experience and infants’ expressive vocabulary development.
