Effects of delayed reinforcement on infant vocalization rate
Journal of the Experimental Analysis of Behavior
|July 1, 1992
Summary
Infant vocalization rates increased with delayed social reinforcement, challenging previous findings. This study demonstrates effective conditioning in infants using a delayed reinforcement schedule.
Area of Science:
- Developmental Psychology
- Behavioral Science
Background:
- Previous research failed to show infant conditioning with a 3-second delay of reinforcement.
- Understanding early learning mechanisms in infants is crucial for developmental studies.
Purpose of the Study:
- To investigate the effects of a delayed reinforcement schedule on infant vocalization rates.
- To explore the efficacy of delayed social reinforcement in 4- to 6-month-old infants.
Main Methods:
- A single-subject repeated-reversal experimental design was employed.
- Three normally developing infants (4-6 months) received delayed social reinforcement for vocalizations.
- A differential reinforcement of other behavior (DRO) schedule controlled for social stimulation.
Main Results:
- Infant vocalization rates significantly increased when the delayed reinforcement schedule was introduced.
- Vocalization rates decreased during the DRO condition compared to baseline operant levels.
- The study successfully demonstrated conditioning in infants using delayed reinforcement.
Conclusions:
- Delayed reinforcement schedules can be successfully implemented to condition vocalizations in young infants.
- Procedural differences may explain the success of this study compared to prior research.
- Findings highlight the potential for delayed reinforcement in early childhood behavioral interventions.

01:24Reinforcement Schedules
Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.

01:08Timing and Consequences on Behavior
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant factor...

01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
