“…Our ongoing work will use the data in the current report to feed into models of language outcome, which may contribute vital knowledge regarding developmental pathways towards successful language acquisition. Whilst in this case measurements were derived using Motion Capture, which requires specialist equipment, the same analyses can be applied to 2D video data using AI technology (e.g., Rocha & Addyman, 2022), or even by measuring the sound signal produced by the drumming infant (e.g., Rocha et al., 2021). The current data can therefore provide distinct added value to neural measures in finding behavioural markers that are suitable for large scale, low cost, screening for intervention.…”

Impaired sensorimotor synchronization (SMS) to acoustic rhythm may be a marker of atypical language development. Here, Motion Capture was used to assess gross motor rhythmic movement at six time points between 5‐ and 11 months of age. Infants were recorded drumming to acoustic stimuli of varying linguistic and temporal complexity: drumbeats, repeated syllables and nursery rhymes. Here we show, for the first time, developmental change in infants’ movement timing in response to auditory stimuli over the first year of life. Longitudinal analyses revealed that whilst infants could not yet reliably synchronize their movement to auditory rhythms, infant spontaneous motor tempo became faster with age, and by 11 months, a subset of infants decelerate from their spontaneous motor tempo, which better accords with the incoming tempo. Further, infants became more regular drummers with age, with marked decreases in the variability of spontaneous motor tempo and variability in response to drumbeats. This latter effect was subdued in response to linguistic stimuli. The current work lays the foundation for using individual differences in precursors of SMS in infancy to predict later language outcomes.Research Highlight We present the first longitudinal investigation of infant rhythmic movement over the first year of life Whilst infants generally move more quickly and with higher regularity over their first year, by 11 months infants begin to counter this pattern when hearing slower infant‐directed song Infant movement is more variable to speech than non‐speech stimuli In the context of the larger Cambridge UK BabyRhythm Project, we lay the foundation for rhythmic movement in infancy to predict later language outcomes

“…While our sample size is typical for lab-based infant visual attention experiments (e.g., Reynolds et al, 2013 ), completion of the study in the home environment may have further introduced noise in the data through environmental variability and the increased presence of distractions. In addition, the Lookit platform is still very new and only few studies using Lookit have been published thus far (e.g., Yoon and Frank, 2019 ; Lapidow et al, 2021 ; Rocha and Addyman, 2022 ). These studies were conducted with 2-year-olds and preschool children.…”

“…Using Lookit helps to recruit more diverse samples and its data quality allows for in-depth analysis of looking behavior ( Nelson and Oakes, 2021 ). Lookit has been utilized in diverse recent studies examining infant development (e.g., Nelson and Oakes, 2021 ; Luchkina and Waxman, 2022 ; Rocha and Addyman, 2022 ; Wang, 2022 ; Colomer and Woodward, 2023 ).…”

Intersensory redundancy impedes face recognition in 12-month-old infants

This study examined the role of intersensory redundancy on 12-month-old infants’ attention to and processing of face stimuli. Two experiments were conducted. In Experiment 1, 72 12-month-olds were tested using an online platform called Lookit. Infants were familiarized with two videos of an actor reciting a children’s story presented simultaneously. A soundtrack either matched one of the videos (experimental condition) or neither of the videos (control condition). Visual-paired comparison (VPC) trials were completed to measure looking preferences for the faces presented synchronously and asynchronously during familiarization and for novel faces. Neither group displayed looking preferences during the VPC trials. It is possible that the complexity of the familiarization phase made the modality-specific face properties (i.e., facial characteristics and configuration) difficult to process. In Experiment 2, 56 12-month-old infants were familiarized with the video of only one actor presented either synchronously or asynchronously with the soundtrack. Following familiarization, participants completed a VPC procedure including the familiar face and a novel face. Results from Experiment 2 showed that infants in the synchronous condition paid more attention during familiarization than infants in the asynchronous condition. Infants in the asynchronous condition demonstrated recognition of the familiar face. These findings suggest that the competing face stimuli in the Experiment 1 were too complex for the facial characteristics to be processed. The procedure in Experiment 2 led to increased processing of the face in the asynchronous presentation. These results indicate that intersensory redundancy in the presentation of synchronous audiovisual faces is very salient, discouraging the processing of modality-specific visual properties. This research contributes to the understanding of face processing in multimodal contexts, which have been understudied, although a great deal of naturalistic face exposure occurs multimodally.

“…Participants completed the current study asynchronously utilizing the online platform Lookit (Scott and Schulz, 2017 ; Scott et al, 2017 ). Lookit has been used in a variety of recent infant studies conducted online (e.g., Nelson and Oakes, 2021 ; Luchkina and Waxman, 2022 ; Rocha and Addyman, 2022 ; Bursalioglu et al, 2023 ; Colomer and Woodward, 2023 ; Wang, 2023 ). The Lookit platform provided us the opportunity to obtain data from participants across the United States and allowed participants to flexibly complete the study on their own schedules.…”

Community diversity and the other-race effect in infancy

The other-race effect (ORE) is characterized by processing advantages for faces of one's own race over faces of another race and is observed at ~9 months of age. Environmental exposure to other races has an impact on the development of the ORE. In the current study, we examined the effects of community racial diversity on the ORE in 9- to 12-month-olds from across the United States. We hypothesized that community racial diversity would influence the amount of experience that infants have with individuals of other races and be an important factor in predicting the ORE across broad regions of the United States. We predicted that infants from more diverse communities would demonstrate successful processing of own- and other-race faces, while infants from less diverse communities would demonstrate successful processing of own-race but not other-race faces. This would indicate that the ORE is exhibited more strongly in infants from less diverse communities than in infants from more diverse communities. Participants completed familiarization and visual paired comparison (VPC) trials with own- and other-race faces in an online study. Our results showed that although the ORE was present, the effect was driven by community members who were the racial majority. Recognition biases were not observed in community racial or ethnic minority participants, potentially due to increased exposure to racial out-group members, which mitigated the development of the ORE in this subset of participants. This study has far-reaching implications in the study of infant face perception, child development, and social justice, as the ORE develops at a young age, and may lead to a complex pattern of racial biases contributing to systemic barriers in society.
