Example
In an auditory oddball experiment, tones are the stimuli, which are categorized as either non-target (low frequency) or target (high-frequency) tones. The distinction of whether the stimulus is a target or non-target is qualified by the stimulus role.
Logical Restrictions
Not all stimuli have roles; in these cases, the stimulus is simply a generic stimulus.
Comments
A stimulus role is played by the Implicit Stimulus or Explicit Stimulus (the latter is characterized by a Stimulus Modality).
Original suggestions included: "The occurrent or continuant (i.e., the thingie) which elicits activity from the subject in the experiment". Its suggested definition in other fields includes:
- Anything that may have an impact or influence on a system
- (physiology) Something external that elicits or influences a physiological or psychological activity or response.
- (psychology) Anything effectively impinging upon any of the sensory apparatuses of a living organism, including physical phenomena both internal and external to the body.
- Anything that induces a person to take action
We define a stimulus as a role so that ontologies of tones, lights, pictures, and other "things" can be imported as references to the objects which play the role of stimulus in a given experimental condition.
