This study examined how coordinated sights and sounds affect infants’ learning about moving objects. Six-month-olds detected changes in both an object’s visual pattern and its trajectory when sounds matched its movement. Mismatched sounds hindered performance, suggesting that multisensory coordination can support early object learning.

Abstract/Description
This study investigated whether infants encode better the features of a briefly occluded object if its movements are specified simultaneously by vision and audition than if they are not (data collected: 2017–2019). Experiment 1 showed that 10-month-old infants (N = 39, 22 females, White-English) notice changes in the visual pattern on the object irrespective of the stimulation received (spatiotemporally congruent audio-visual stimulation, incongruent stimulation, or visual-only; ηₚ² = .53). Experiment 2 (N = 72, 36 female) found similar results in 6-month-olds (Test Block 1, ηₚ² = .13), but not 4-month-olds. Experiment 3 replicated this finding with another group of 6-month-olds (N = 42, 21 females) and showed that congruent stimulation enables infants to detect changes in object trajectory (d = 0.56) in addition to object pattern (d = 1.15), whereas incongruent stimulation hinders performance.
