Newborns show a significant heart rate deceleration during the grasping reflex. This reflex, involving grasping a mother's hand, may offer a calming effect and therapeutic benefits for infants.

Area of Science:

  • Neonatal physiology
  • Developmental psychology
  • Infant behavior

Background:

  • The grasping reflex is an innate behavior in newborns.
  • Physiological responses during early infant reflexes are not fully understood.
  • Attachment behaviors in newborns play a crucial role in early development.

Purpose of the Study:

  • To investigate heart rate changes as a psychophysiological indicator during the neonatal grasping reflex.
  • To explore the relationship between the grasping reflex and infant state regulation.
  • To assess the potential calming and therapeutic effects of reflex grasping.

Main Methods:

  • Studied 27 full-term healthy newborns within 2.5-50 hours after birth.
  • Measured heart rate changes as a psychophysiological response during the grasping reflex.

  • Observed the grasping reflex, specifically grasping a mother's hand.

    • Main Results:

    • A significant heart rate deceleration was observed concurrently with the grasping response.
    • This physiological change suggests a link between the reflex and the infant's autonomic nervous system state.
    • The grasping reflex may indicate a state of focused attention or engagement.

    Conclusions:

    • Reflex grasping of a mother's hand may be a component of human attachment behavior.
    • This interaction could have a positive calming effect on the infant's state.
    • The findings suggest potential therapeutic value for high-risk mother-infant dyads.
