In order to fade prompts on the steps being targeted the learner must show increased independence. [4] The fading technique used will be most to least because the skills being worked on are new. The prompts will be decreased to least intrusive when the learner shows increased ability to complete the task with less assistance. [6]
The goal of response prompting is to transfer stimulus control from the prompt to the desired discriminative stimulus. [1] Several response prompting procedures are commonly used in special education research: (a) system of least prompts, (b) most to least prompting, (c) progressive and constant time delay, and (d) simultaneous prompting.
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.
For example, asking the student the question "what is this?" (this would be an example of an impure tact) has been used to prompt a correct tact response (this prompt can be faded until the learner can emit a pure tact). Echoic prompts (teacher repeats the correct answer which the learner must echo) have also been used to train tact responses.
The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
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. [5]
Chaining is a type of intervention that aims to create associations between behaviors in a behavior chain. [1] A behavior chain is a sequence of behaviors that happen in a particular order where the outcome of the previous step in the chain serves as a signal to begin the next step in the chain.
The training protocol is based on the principles of applied behavior analysis. [3] The goal of PECS is spontaneous and functional communication. [3] The PECS teaching protocol is based on B. F. Skinner's book, Verbal Behavior, such that functional verbal operants are systematically taught using prompting and reinforcement strategies that will lead to independent communication.
