Natural Environment Training (NET) 


Developed by Drs. Sundberg and Partington.  This type of training allows for more natural manding opportunities, increases generalization, and promotes spontanteous  verbal behavior.  The use of NET focuses on the individual's motivation and consequences directly related to their motivation.  Using this method, may aide in the reduction of negative behaviors while maintaining and increasing functional replacement skills.

(Hall & Sundberg, 1987; Koegal, Koegal, & Surratt, 1992; Stafford, Sundberg, & Braam, 1988).

Discrete Trial Training (DTT) or Intensive Teaching Trials (ITT)


(e.g., Lovaas, 1981; Lovaas, Koegal, Simmons, & Long, 1983; Smith, 1983) is language intervention conducted in a highly specified and structured manner allowing for a high number of training trials. ITT denotes the addition of a certain set of teaching procedures (e.g., errorless teaching, mixing and varying, pairing, variable ratio schedules of immediate reinforcement, short ITI's) and the use of Skinner's analysis of verbal behavior to guide instruction.
