What typically reinforces emitting a correct echoic?

The reinforcement of emitting a correct echoic is primarily driven by praise and attention. When a child correctly echoes verbal stimuli, receiving praise and attention serves as a positive reinforcement that encourages the behavior to occur again in the future. This is fundamental in behavior analysis, as attention and social reinforcement are powerful motivators, particularly in young learners.

When a child hears their echoic correctly acknowledged, it boosts their confidence and establishes an association between the behavior (correct echoic) and a positive outcome (praise or attention). This creates a favorable environment for learning and promotes further verbal behaviors.

Other options do not typically serve as primary reinforcers for echoic responses in the same way. For example, letting the child escape or tangibles might not be directly tied to verbal behavior reinforcement. Prior knowledge, while important for learning, does not act as a reinforcer in this context; instead, it's the verbal interaction and social connection that significantly reinforce the correct echoic response.
