Exposure Therapy
A cognitive behavioral therapy technique for reducing fear and anxiety responses, especially phobia, based on the principles of habituation and cognitive dissonance. It is similar to systematic desensitization, though it works more quickly and produces more robust results.[citation needed] It is also very closely related to exposure and response prevention, a method widely used for the treatment of obsessive-compulsive disorder.

Cognitive Behavior Therapy
A form of psychotherapy that emphasizes the important role of thinking in how we feel and what we do. Cognitive-behavioral therapy does not exist as a distinct therapeutic technique.  The term "cognitive-behavioral therapy (CBT)" is a very general term for a classification of therapies with similarities.  There are several approaches to cognitive-behavioral therapy, including Rational Emotive Behavior Therapy, Rational Behavior Therapy, Rational Living Therapy, Cognitive Therapy, and Dialectic Behavior Therapy.

Behavioral Therapy
This will teach a child how to effectively cope with his/her behavior and also guide him/her to more socially appropriate behaviors. An autistic child usually has no sense of social awareness and he needs to be taught the skills in a specific manner. Usually, a behavioral therapy program comprises of 4 sections: a structured daily routine; behavioral control; communication; and applied behavioral analysis.

Applied Behavior Analysis (ABA)
Behavior analysis is a scientific approach to understanding behavior and how it is affected by the environment. “Behavior” refers to all kinds of actions and skills (not just misbehavior), and “environment” includes all sorts of physical and social events that might change or be changed by one's behavior. The science of behavior analysis focuses on principles (that is, general laws) about how behavior works, or how learning takes place. For example, one principle of behavior analysis is positive reinforcement: When a behavior is followed by something that is valued (a “reward”), that behavior is likely to be repeated. Through decades of research, the field of behavior analysis has developed many techniques for increasing useful behaviors and reducing those that may be harmful or that interfere with learning. Applied behavior analysis (ABA) is the use of those techniques and principles to address socially important problems, and to bring about meaningful behavior change.

Discrete Trial Methods
Discrete Trial teaching is a specific method of teaching used to maximize learning.  It is a teaching technique or process used to develop many skills, including cognitve, communication, play, social and self help skills.  It is just good teaching.
