Which of the following strategies promotes skill acquisition through reinforcement?

• A. Extinction techniques
• B. Positive Reinforcement
• C. Punishment methods
• D. Shaping without reinforcement

Answer: (B)

Positive reinforcement is a strategy that effectively promotes skill acquisition by providing a desirable consequence following a desired behavior. This approach reinforces the behavior, making it more likely that the individual will repeat it in the future. For instance, when a person with autism learns to communicate using words and receives praise or a tangible reward, the likelihood of using those words again increases. The principle behind positive reinforcement is rooted in behaviorism, which emphasizes the role of consequences in shaping behavior.

In contrast, extinction techniques involve the removal of reinforcement to reduce undesirable behaviors, which does not actively promote skill acquisition. Punishment methods can suppress behaviors but do not necessarily teach new skills or encourage the acquisition of desired behaviors. Shaping without reinforcement focuses on gradually guiding behavior toward a target but lacks the incentive that reinforcement provides, making it less effective for skill acquisition. Therefore, positive reinforcement stands out as the most effective strategy for encouraging the learning and repetition of new skills.
