Which technique emphasizes providing positive feedback when observing desired behaviors?

The technique that emphasizes providing positive feedback when observing desired behaviors is behavioral reinforcement. This approach is rooted in behaviorism, which focuses on the idea that behaviors can be increased or decreased through reinforcement strategies. When a therapist observes a client demonstrating a desired behavior, offering positive feedback acts as a reinforcement, encouraging the client to repeat that behavior in the future. This method is effective because it not only acknowledges the effort of the client but also motivates them to continue engaging in positive behavior changes.

In contrast, systemic feedback involves understanding and addressing the broader context of a client's relationships and interactions but does not specifically focus on providing reinforcement for individual behaviors. Narrative techniques are about reshaping a person's story or the meaning they give to their experiences rather than concentrating on reinforcing specific behaviors. Solution-focused interventions prioritize identifying solutions and strengths in clients' lives, again not centering on the reinforcement of particular behaviors like behavioral reinforcement does.

Thus, behavioral reinforcement is the appropriate choice for emphasizing positive feedback in response to desired behaviors.
