Discrete trial training (DTT) is a process whereby an activity is divided into smaller distinct sub-tasks and each of these is repeated continuously until a person is proficient. The trainer rewards successful completion and uses errorless correction procedures if there is unsuccessful completion by the subject to condition them into mastering ...
Instruction ends when the learner reaches a criterion level (e.g., 100% correct for 3 consecutive days) during probe sessions. The primary advantage of simultaneous prompting, when compared with time delay procedures, is that a learner does not need to have the prerequisite skill of waiting for a prompt if he or she cannot independently emit ...
[citation needed] In 1974 Ole Ivar Lovaas, pioneer of the use of discrete trial teaching (DTT) to treat autism, was the second author on a journal article describing the use of ABA to reduce "feminine" behaviors and increase "masculine" behaviors of a male child in an effort to prevent adult transsexualism.

Ole Ivar Løvaas (8 May 1927 – 2 August 2010) [1] [2] was a Norwegian-American clinical psychologist and professor at the University of California, Los Angeles.He is most well known for his research on what is now called applied behavior analysis (ABA) to teach autistic children through prompts, modeling, and positive reinforcement.
Pivotal response treatment (PRT), also referred to as pivotal response training, is a naturalistic form of applied behavior analysis used as an early intervention for children with autism that was invented by Robert Koegel and Lynn Kern Koegel. PRT advocates contend that behavior hinges on "pivotal" behavioral skills—motivation and the ...
Discrete trial training (DTT) is a structured and systematic approach utilized in helping individuals with autism spectrum disorder learn. [64] Individuals with autism tend to struggle with learning through observation, therefore something that is reinforcing is necessary in order to motivate them to imitate or follow through with the task.

The errorless learning procedure is highly effective in reducing the number of responses to the S− during training. In Terrace's (1963) experiment, subjects trained with the conventional discrimination procedure averaged over 3000 S− (errors) responses during 28 sessions of training; whereas subjects trained with the errorless procedure averaged only 25 S− (errors) responses in the same ...
The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
