Dr Sinead Rocha from the CNE Babylab has a new pre-print out -  An investigation of novel carrying experience on infant rhythm perception.


Prior research suggests infants who are regularly carried in an infant sling are more accurate at moving in time with an auditory rhythm. Moreover, the rate of walking cadence during infant carrying was found to impact infant spontaneous motor tempo. In the current study we ask if part of the advantage of locomotive experience on sensorimotor synchronization results from greater sensorimotor neural activation, utilized to predict the beat, during the perception of rhythmic auditory stimuli. Five-month-old infants were carried at either a Fast or Slow rate. EEG was then used to measure infants’ recruitment of a sensorimotor program, indexed by sensorimotor alpha suppression, during the auditory presentation of the Fast and Slow rhythms. Our results suggest that infants do not seem to preferentially exploit a sensorimotor representation when hearing an auditory tempo that matched the rate at which they were carried, compared to when hearing an incongruent tempo.
