The ontogenesis of agent: cognitive notion
Journal of Speech and Hearing Research
|June 1, 1982
Summary
Early child language, including 1- and 2-word utterances, suggests the agent concept originates from sensorimotor development. This study observed nonverbal agent awareness in infants aged 11-22 months.
Area of Science:
- Developmental psychology
- Linguistic development
- Cognitive science
Background:
- The semantic concept of 'agent' in early language development is linked to sensorimotor skills.
- Prior research connects the nonverbal agent concept to causality and requests for action in young children.
Observation:
- Three children were observed from 11 to 22 months of age in their homes.
- Gestural behaviors during request interactions with mothers and an investigator defined nonverbal agent awareness.
- Observations occurred monthly during free play and structured tasks designed to elicit requests for help.
Findings:
- A 5-level developmental sequence of the cognitive notion of agent was documented.
- Children's nonverbal behaviors evolved over 12 months, indicating developing agent awareness.
- Early utterances and gestural actions suggest a sensorimotor origin for the agent concept.
Implications:
- Findings suggest sensorimotor development is foundational for early semantic understanding.
- This research provides insights into the developmental trajectory of agency in infants.
- Understanding the evolution of the agent concept can inform early childhood language and cognitive development interventions.
