Single-Stimulus Preference Assessment
Also called: successive choice, SS preference assessment
Definition
A preference assessment in which items are presented one at a time and the person's response to each — approach, engagement, or duration of contact — is recorded. It is the simplest format and suits people who do not yet choose between two items, but it can overrate items because nothing is being compared.
In plain language
Show one item at a time and see how the person reacts to it. Simple, and good for people who cannot yet pick between two things.
Example
A bubble wand is offered on its own; the learner reaches for it and plays for two minutes. Then a ball is offered on its own.
Not single-stimulus preference assessment
Two items offered together and the chosen one recorded. That is a paired-stimulus format.
