Stimulus prompt
A type of prompt that increases the salience of the SD and calls an individual’s attention to the stimulus that directs behavior, which is gradually faded out until the correct
Stimulus salience
The process of making learning stimuli more prominent to establish stimulus control and skill acquisition.

Stimulus shape transformations
A method of fading stimulus prompts by starting with a stimulus that controls the desired response and systematically and gradually changing the shape of that stimulus into the SD that
Subject confounds
Any uncontrolled participant-related variables that may interfere with the outcomes of an intervention and therefore the internal validity of an experiment.
Successive approximations

Symbolic matching-to-sample
A matching-to-sample procedure where clients are taught to match sample and comparison stimuli that are symbolically related, and not physically identical.
Symmetry
Defined as the trained relation of symbolically similar items and the demonstration of the relation in reverse without additional direct training (i.e., if A=B, then B=A).
Synthesized FA
A variation of the functional analysis that uses an Interview Informed Synthesized Contingency Analysis (IISCA) to hypothesize the contingencies that may maintain challenging behavior and then testing those hypothesized contingencies.
