Neo-behaviorism introduced cognitive elements into traditional behaviorism. It recognizes that behavior cannot be fully understood by stimuli and responses alone. Tolman's purposive behaviorism viewed learning as goal-directed and involving cognitive maps. It found that reinforcement is not essential for learning. Bandura's social learning theory emphasized observation and modeling, recognizing that learning can occur without behavior change. Neo-behaviorism represents a transition between behaviorism and cognitive learning theories.
