“…Our prior analyses (Thurman & Corbetta, 2017, 2019), using standard frequency analyses and durations for how long infants assumed certain postures, revealed that infants used sitting postures most of the time, but that the amount of sitting declined as they acquired upright locomotion and it was progressively superseded by the use of other postures such as standing during the walking period. Infants also significantly increased overall transitions between postures over time, but in prior reports, we did not detail transitions between postures, identify which transitions between postures were the most frequent, or even describe the increasing complexity of the postural network over developmental time.…”

“…Further, infants diversified their behaviors with targets as they acquired new postures. Certain postures seemed to be preferred for specific interactive manual behaviors, but the selected postures for those specific manual behaviors changed over time (Thurman & Corbetta, 2019).…”

“…Postural development in infancy is one of those behaviors that has been characterized as a highly variable complex system that constantly changes, organizes, and reorganizes over time, until stable states emerge (Thelen & Smith, 1994). Infants also constantly transition from one posture to another as they interact with their environment (Thurman & Corbetta, 2019). These characteristics of the development of postural‐locomotor progression provide an excellent opportunity to illustrate the advantage of network analysis principles.…”

“…We intentionally utilize a subset of empirical data from a prior longitudinal study that documented infants’ use and shifts of postures during free play over the developmental progression from sitting to walking using traditional frequency analysis (Thurman & Corbetta, 2017, 2019). Some major findings from those reports concerned infants’ spatial exploration and use of postures for interacting with targets during a free‐play session.…”

Network analysis is a tool typically used to assess interrelationships between social entities in a system. In this methodological report, we introduce how concepts from network analysis can be utilized to capture, condense, and extract complex developmental changes in individual behaviors over time. Using infant postural-locomotor de-928 | THURMAN ANd CORBETTA 1 | INTRODUCTION Development is a complex process, especially in infancy when change occurs rapidly. Further, individual infants influence and are influenced by a multitude of factors that can interact in diverse ways and create unique developmental contexts where the infants' intrinsic characteristics, the people and resources in their local environments, and the cultural values and traditions interact in specific ways. These complex webs of interactions can change continuously as children or their sociohistorical environments develop over time (e.g., Bronfenbrenner, 1977, 1986; Cochran & Brassard, 1979); they also directly influence the way infants behave and act on their environment. For developmentalists, capturing and examining complex developmental changes, between and/or within systems, can be difficult. Creative approaches are needed in order to identify rich trends present in such complex developmental systems data. In recent decades, advancements have been made in methodologies aimed at studying complex systems in infant development, mostly inspired or influenced by the dynamic systems framework. Examples of existing lag-sequential representational techniques involve recurrence plots (RPs) and state-space grids (SSGs). Each of these techniques is often used to detect patterns in repeatedly measured behavior coded continuously from videos and has most commonly been applied in developmental literature to investigate dyadic mother-child interactions. RPs were introduced by Eckmann et al. (1987) and rely on time-series data to highlight recurring patterns between events or behaviors taking place within a particular system, such as a mother-infant dyad. They provide a graphical representation that instantly reveals whether the behaviors occurring in the system adopt periodic or chaotic patterns (e.g., Marwan et al., 2007). Yu and Smith (2013) used RPs to show how parents and infants coordinate joint attention during play by looking at objects being held as opposed to looking at the faces of their social partners. In a similar vein, SSGs, developed by Lewis, Lamey, and Douglas (1999), have been used to provide a visual representation of the relationship between two concurrent variables, often between parent and child, where each individual's movement is represented through different affective states (Hollenstein, 2007). For example, one recent study revealed differences in how fathers and mothers interacted with their infants using SSGs. The researchers found that infant-father dyads changed states more often than infant-mother dyads, whose interactions were more repetitive (Cerezo et al., 2017). These analytical tools have brought greater insight to o...

Infants’ developing motor skills—including mastery of new postures such as sitting and standing—affect opportunities for learning that facilitate cognitive development. But how infant posture affects caregiver behavior is largely unexplored. Moreover, we know little about effects of posture on learning opportunities in infants with motor delay. This study asked how infants with typical development and infants with significant motor delay use various postures during play, and whether posture is related in real time to caregiver‐provided cognitive learning opportunities. Infants were videotaped five times over the course of a year in a free play session with a caregiver, starting when they demonstrated initial sitting skills. Posture and cognitive opportunities were coded moment‐by‐moment to assess duration and temporal overlap. We found that infants with typical development and infants with motor delay displayed similar use of postures initially, but infants with typical development demonstrated more mature postures over time. We also found that for both groups of infants, caregivers were most likely to provide cognitive opportunities when infants were sitting independently, and least likely when infants were supine. Our findings highlight the importance of upright sitting in typical and atypical infant development and suggest potential areas of intervention for infants with motor delay.

This longitudinal study investigates infants' touching behaviors with others during naturalistic observations in a daycare center in Japan. Interactions between eight infants and their caretakers during free play time were videotaped. The obtained data were examined based on infants' postures and the body parts used to engage in interpersonal touch during locomotor development. As the locomotor period progressed from crawling to walking, the infants made bodily contact more frequently. When they were crawlers, incidental touch occurred often, but with progress in locomotion, purposeful (instrumental and social) touch became more common. Infants' purposeful touch occurred more frequently when they used their hands than when they used other body parts to touch. Touching with hands was more frequent when (a) infants who were able to walk were in walking postures than when they were unable to walk and in crawling postures; (b) infants who could walk were in sitting postures than when they could not walk and were in sitting postures, and (c) infants who could walk were in standing postures than when they were in sitting postures. Infants' locomotor development freed infants' hands from locomotion, and overall progress in physical coordination helped infants maintain balance. These advances in motor development made infants' touch behaviors social.
