Final answer:
Modeling methods are indeed utilized in behavior therapy for anger management and ADHD, as supported by Bandura's social learning theory and empirical evidence, making the statement true.
Step-by-step explanation:
The main answer to whether modeling methods have been used in treating people with anger management issues and in teaching new behaviours to children with attention-deficit/hyperactivity disorder (ADHD) is true. Modeling is a form of therapy that involves demonstrating desired behaviors that others can emulate, which is effective in both scenarios. Albert Bandura's social learning theory fundamentally supports this approach, where he identified three kinds of models: live, verbal, and symbolic. Live models demonstrate the behavior in person, verbal models explain or describe the behavior without performing it, and symbolic models can be characters or individuals that perform behaviors in media formats. These methods have been shown to influence both prosocial and antisocial behaviors in observational learning. Moreover, treatment for ADHD often involves behavioral therapies that incorporate aspects of modeling to teach new behaviors and coping strategies.In conclusion, modeling methods are indeed used as a practice in behavior therapy for anger management and ADHD, proving the statement to be true.
