Answer:
A). B. F. Skinner.
Step-by-step explanation:
B.F. Skinner, the highly acknowledged psychologist as well as greatly admired behaviorist and philosopher in his book designated 'Verbal Behavior' proposed the idea that the children learn speech patterns through similar reinforcement techniques to learn to speak as employed by animals to acquire non-verbal behaviors.
He illustrated this through the use of an experiment that shows how an animal learns to react to get their food that functions as a 'reward' which exemplifies positive reinforcement. Identically, a child learns to speak through the prompts in the form of praise or admiration which evokes a positively reinforced behavior from them. Therefore, option A is the correct answer.
