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 ...
Discrete trials were originally used by people studying classical conditioning to demonstrate stimulus–stimulus pairing. [citation needed] Discrete trials are often contrasted with free operant procedures, like ones used by B.F. Skinner in learning experiments with rats and pigeons, to show how learning was influenced by rates of reinforcement.
The initial procedure was the incidental teaching procedure. [6] The natural language training approach is often contrasted with discrete trial approaches. [7] In discrete trial program there is a clear trial window and only the first response is scored. If incorrect no reward is delivered and the trainer moves to the next trial.
The progressive time delay procedure was developed first, [12] and the constant time delay procedure was developed as a more parsimonious procedure for teaching students with disabilities. [13] CTD and PTD are systematic procedures that use the teaching strategy of waiting on a learner's response that has likely been used haphazardly for years. [6]
ABA is an applied science devoted to developing procedures which will produce observable changes in behavior. [3] [9] It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research, [10] but it uses principles developed by such research, in particular operant conditioning and classical conditioning.
Many intensive behavioral interventions rely heavily on discrete trial teaching (DTT) methods, which use stimulus-response-reward techniques to teach foundational skills such as attention, compliance, and imitation. [61] However, children have problems using DTT-taught skills in natural environments. [5]

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 ...
