The Emergence of Self-Awareness in Preterm Infants: Insights From the Rooting Reflex

Area of Science:

• Neonatal development
• Infant sensory processing
• Developmental psychology

Background:

• Touch is the earliest developing sense.
• Sensory exploration in preterm infants may foster early self-awareness.
• The rooting reflex is a key indicator of early sensory processing.

Purpose of the Study:

• To demonstrate the emergence of sensory self-awareness in preterm infants.
• To analyze behavioral responses of the rooting reflex in relation to stimulation type.
• To investigate if preterm infants exhibit a preference for self-stimulation.

Main Methods:

• Prospective study of preterm infants (24-37 weeks gestational age).
• Rooting reflex assessed via video in response to external and self-stimulation.
• Comparison of four progressively complex behavioral responses between stimulation types.

Main Results:

• Behavior 3 (mouth opening/tongue protrusion without head movement) was significantly more frequent during self-stimulation (35.7%) versus external stimulation (24.9%).
• A statistically significant difference was observed (p=0.005).
• No significant differences were found for other rooting reflex behaviors.

Conclusions:

• Rooting reflex responses in preterm infants are dependent on stimulation type, with a preference for self-stimulation.
• This preference suggests an early capacity to distinguish self from non-self.
• Findings provide insights into preterm infant sensory processing and developmental care.
