Under B. F. Skinner's Operant Conditioning Theory, the concept of 'Shaping'—whereby a complex or entirely novel desired behavior is established gradually rather than achieved all at once, by providing reinforcement to successive approximations of the target behavior—is best explained by which of the following scientifically valid psychological statements regarding its classroom application for complex skill acquisition?

Understanding Shaping in Operant Conditioning

In B. F. Skinner's Operant Conditioning, Shaping (the method of successive approximations) is the process used to teach complex or new behaviors that are not part of an organism's current repertoire.

• Successive Approximations: Every small step that comes closer to the final target behavior is positively reinforced.
• Gradual Development: Instead of waiting for the final complex behavior to occur spontaneously, closer and closer approximations are rewarded until the desired behavior is fully established.
• Classroom Implications: This method is highly effective in teaching difficult and lengthy skills (such as writing, conducting scientific experiments, etc.) in a step-by-step manner.

Therefore, option (b) is the most accurate and scientifically valid statement.
