Self-Organization in Spontaneous Movements of Neonates generates Self-specifying Sensory Experiences

TL;DR

This study investigates how spontaneous neonatal movements self-organize to generate sensory experiences that contribute to developing body awareness, highlighting the role of movement patterns in early self-perception.

Contribution

It introduces a symbolic dynamics approach to analyze neonatal limb movements, revealing self-organizing patterns linked to body awareness development.

Findings

Identification of 16 coordination patterns in neonatal movements

Shift from proximal to distal movement configurations with age

Evidence of self-organization providing sensory stimuli for body awareness

Abstract

Movement experience and the coordination of perception and action are the basis of developing body awareness, emotion, motivation and cognition and the sense of self. The four limbs play a key role in the developing sense of body ownership, agency and peripersonal space. Neonatal limb movements were investigated respective processes of self-organization and developing body awareness. Application of symbolic dynamics to kinematic data of radial distance trajectories of the hands and feet determined 16 coordination patterns according to the distance of the effectors to the body center. From time series analysis of occurrence and recurrence of these configurations of 25 movement episodes of 14 infants both characteristics of self-organization as well as features assumed to provide neonates with experiences involved in the development of body awareness were found. With increasing age a shift from configurations with proximal to distal positions suggests a role of the proximal-distal dimension in movement development. We conclude that self-organization in spontaneous movements provides neonates with perceptual body- and self-specifying stimuli involved in developing body awareness and postulate the involvement of emotional and cognitive processes.
