Which term refers to stimuli that vary across physical dimensions but have a common effect on behavior?

Which term refers to stimuli that vary across physical dimensions but have a common effect on behavior?

• A. Topography
• B. Stimulus Class
• C. Trend (as in baseline)
• D. Elicited

Answer: (B)

Stimulus class describes a group of stimuli that differ in physical dimensions but share the same effect on behavior. So, even if they look different—varying in color, shape, size, or other features—these stimuli function the same for the organism and elicit the same responses or signaling the same reinforcement. This is why the term fits: all the varied stimuli produce the same behavioral outcome, capturing the idea of functional equivalence rather than physical similarity. Topography is about the form of a response, not about grouping different stimuli by their effects. Elicited refers to a response brought about by a stimulus, not to a set of diverse stimuli that share a function. Trend (as in baseline) relates to data patterns over time, not stimulus relationships.
