Rhythm perception, production, and synchronization during the perinatal period

Area of Science:

• Developmental psychology
• Neuroscience
• Human infant behavior

Background:

• Sensori-motor synchronization (SMS) is key to motor, cognitive, and social functions.
• SMS research typically focuses on adults and children over four years old.
• Investigating SMS in younger populations is limited by methodological challenges.

Purpose of the Study:

• To review existing knowledge on sensori-motor synchronization (SMS) in fetuses, infants, and newborns.
• To explore the capabilities of pre-verbal humans in perceiving and producing rhythmic patterns.
• To determine if newborns can adjust their motor behavior to external rhythmic stimuli.

Main Methods:

• Review of studies on fetal and infant perception and production of rhythm.
• Analysis of spontaneous motor behaviors (sucking, crying, leg movements) in response to auditory rhythms.
• Examination of cross-modal rhythmic perception and production in infants.

Main Results:

• Evidence suggests rhythm perception and production exist in fetuses and infants.
• Newborns demonstrate SMS under specific conditions, particularly near their natural motor tempo.
• Interaction between auditory rhythms and motor activity is present at birth.

Conclusions:

• Sensori-motor synchronization (SMS) is an innate ability present from birth.
• SMS in early infancy occurs within a limited tempo range and specific contexts.
• This early synchronization plays a fundamental role in infant interaction and communication.
