简介：

Overview

This protocol presents a novel methodology for the neural decoding of intent from freely-behaving infants during unscripted social interaction with an actor. Neural activity is acquired using non-invasive high-density active scalp electroencephalography (EEG) and kinematic data is collected with inertial measurement units.

Key Study Components

Area of Science

• Neuroscience
• Developmental Psychology
• Social Cognition

Background

• This study investigates the neural basis of cognitive motor development in infants.
• It explores the emergence of social cognition during the first two years of life.
• The method allows for the acquisition of neural activity in action and context.
• It aims to address developmental milestones and learning by imitation.

Purpose of Study

• To capture brain activity and kinematic data from infants.
• To understand the relationship between brain architecture and behavior.
• To study the functioning of the mirror neuron system in early human brain development.

Methods Used

• Placement of EEG cap on the infant's head with acceptable impedance levels.
• Securing inertial measurement units on the infant and experimenter.
• Interaction with the infant to initiate imitation responses.
• Recording EEG and kinematic data during the interaction.

Main Results

• Successful acquisition of EEG and kinematic data from infants.
• Insights into how infants process visual actions and engage in social communication.
• Identification of various behaviors elicited during the experiment.
• Potential implications for therapy of social cognition problems and autism spectrum disorders.

Conclusions

• This methodology provides a unique approach to studying cognitive development in infants.
• It enhances understanding of the neural mechanisms underlying social cognition.
• The technique can be applied to other cognitive systems such as language processing and motor planning.
