PART 29 : DISCRETE TRIAL TRAINING
QUESTIONS & ANSWERS(RATED A+)
discrete trial training (DTT) - ANSWER- ABA based intervention
- starts with task analysis & all those smaller skills are taught individually through
repetition of stimulus prevention
- then they are recombined into larger skills & are taught for generalization,
discrimination & maintenance
history of DTT - ANSWER- ivar lovaas
- 1960s
- institutionalized children with autism

primary reinforcement - ANSWERunlearned, biologically innate reinforcement that
does not require teaching such as food
conditoned reinforcement - ANSWERreinforcement that is learned via pairing with
primary reinforcement
common features of DTT - ANSWER- extensive use of task analysis
- shaping of response chains (putting skills together in order)
- reliance on visual schedules
- fast paced, massed trials (keep learner's attention)
- careful mix of easy trials with emerging & novel trials
