Pivotal response treatment is a naturalistic intervention model derived from the principles of applied behavior analysis.Rather than target individual behaviors one at a time, PRT targets pivotal areas of a child's development such as motivation, [3] responsiveness to multiple cues, [4] self-management, and social initiations.

The field of behavior analysis grew out of the scientific study of principles of learning and behavior. It has two main branches: experimental and applied behavior analysis. The experimental analysis of behavior (EAB) is the basic science of this field and has over many decades accumulated a substantial and well-respected research literature.
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.
Discrete trial training (DTT) is a technique used by practitioners of applied behavior analysis (ABA) that was developed by Ivar Lovaas at the University of California, Los Angeles (UCLA). DTT uses mass instruction and reinforcers that create clear contingencies to shape new skills.
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.
It is intended to be used by individuals who have training in applied behavior analysis (ABA) and is primarily used by behavior analysts, speech-language pathologists, school psychologists and special educators to assess strengths and weaknesses in skills and behaviors that might impede language and social development.
[1] [2] [3] Concurrent designs are the traditional approach to multiple baseline studies, where baseline measurements of all participants start at (roughly) the same moment in real time. This strategy is advantageous because it moderates several threats to validity , and history effects in particular.
The data are updated at three-month intervals (i.e., 6 months, 9 months, 12 months) in order to track the specific changes in skills over the course of the children's development. These preliminary data have been collected in a systematic manner to provide information about when each skill measured by the ABLLS-R is usually acquired by ...
