Noncontingent stimulation, stimulus familiarization, and subsequent learning in young infants
Child Development
|December 1, 1984
Summary
Infants develop expectations about how objects should behave based on prior experience. Familiarizing infants with a mobile before training prevented learning, while noncontingent exposure did not hinder operant conditioning.
Area of Science:
- Developmental Psychology
- Infant Learning
- Behavioral Development
Background:
- Infant learning is influenced by early experiences.
- Understanding how prior exposure affects operant conditioning in infants is crucial for developmental research.
Purpose of the Study:
- To investigate the impact of noncontingent and familiarization experiences on subsequent operant conditioning in young infants.
- To determine if prior exposure to a mobile affects an infant's ability to learn a new association.
Main Methods:
- Two experiments were conducted with young infants.
- Experiment 1: Assessed effects of short- and long-term noncontingent mobile exposure versus passive viewing.
- Experiment 2: Used long-term familiarization with the training mobile.
Main Results:
- Prior noncontingent experience did not impede subsequent operant conditioning in either experiment.
- Long-term familiarization with the training mobile in Experiment 2 prevented evidence of learning.
- Infants demonstrated learning through kick-produced mobile movement.
Conclusions:
- Infants form expectancies about stimulus behavior based on prior experiences.
- Familiarization can interfere with learning, whereas noncontingent exposure does not negatively impact operant conditioning in infants.
