Action perception in infancy: the plasticity of 7-month-olds' attention to grasping actions

Area of Science:

• Developmental psychology
• Cognitive neuroscience
• Infant perception

Background:

• Infants orient attention towards grasping actions.
• This attention shift shows a priming effect.
• Mechanisms and malleability of this priming are unknown.

Purpose of the Study:

• Investigate plasticity of infant attention during grasping perception.
• Examine how novel action-contingencies affect attention priming.
• Understand the adaptability of infant action perception.

Main Methods:

• Used a spatial-cueing paradigm with 7-month-old infants.
• Implemented training trials to introduce novel action-target contingencies.
• Assessed attention shifts during perception of grasping actions.

Main Results:

• Brief exposure to new action-target rules modulated infants' attention.
• The observed priming effect was significantly altered by training.
• Infants demonstrated rapid adaptation to new contextual regularities.

Conclusions:

• Infant attention to grasping actions is highly plastic.
• Action perception adapts quickly to observed regularities.
• Grasping experience is not the sole determinant of attention shifts.
