The infant's concept of agency: the distinction between social and nonsocial objects
1Department of Psychology/CRDH, Concordia University, Montreal, Quebec, Canada.
Insights
By 1 year old, infants can differentiate between social agents and inanimate objects. Younger infants show more interest in animate agents, while older infants process anomalous events longer.
Area of Science:
- Developmental Psychology
- Cognitive Science
- Infant Perception
Background:
- Understanding agent perception in infants is crucial for developmental psychology.
- Early distinctions between social and nonsocial agents inform theories of cognitive development.
Purpose of the Study:
- To investigate young infants' ability to discriminate between social and nonsocial objects as agents.
- To determine the developmental trajectory of agent perception in the first year of life.
Main Methods:
- Studied 31 infants aged 8 months to 14 months.
- Assessed communicative skills via frustration episodes involving toy removal.
- Measured visual fixation time comparing events with inanimate vs. animate agents.
Main Results:
- Younger infants (8-10 months) showed greater interest in animate agents.
- Older infants (12-14 months) took longer to process anomalous events involving inanimate agents.
- Infants demonstrated differential attending responses based on agent type.
Conclusions:
- Findings suggest infants develop the capacity to distinguish causal powers of social and nonsocial objects by 12 months.
- This discrimination is a foundational element in developing social cognition.
- Early agent perception abilities predict later social understanding.
Abstract:
The primary purpose of this study was to examine young infants' discrimination between the abilities of social and nonsocial objects to serve as agents. Thirty-one infants between 8 months and 8 days old and 14 months and 19 days old were studied. The children's communicative skills were evaluated through frustration episodes in which a toy was taken away in order to elicit communicative behaviors toward the mother. Visual fixation time was compared for events in which an inanimate object moved independently and events in which a human being was the agent. Analysis of the magnitude of decrease of attending responses revealed that the older infants took longer to process anomalous events, whereas the younger infants manifested more interest for events in which an animate being played the role of agent. The findings suggest that infants can distinguish between the causal powers of social and nonsocial objects by the end of the first year.
