Board Certified Behavior Analyst (BCBA) Practice Test

Stimulus equivalence involves matching which of the following?

1. Words to sounds

2. Images to actions

3. Printed words to actual objects

4. Concepts to definitions

The correct answer is: Printed words to actual objects

Stimulus equivalence is a fundamental concept in behavior analysis that describes how different forms of stimuli can be related through learned associations. In the context of the correct answer, matching printed words to actual objects exemplifies the concept of stimulus equivalence because it demonstrates the ability to recognize that a written word (the printed word) and a physical item (the actual object) can represent the same underlying concept. This matching shows that an individual can understand the relationship between a symbol (the printed word) and a tangible entity (the object), highlighting the learner's ability to transfer knowledge across different modalities of stimuli. Such matches are vital for language development and comprehension, as they reinforce the understanding that symbols can stand in for real-world objects. Matching words to sounds, images to actions, and concepts to definitions, while they all involve relations between stimuli, do not necessarily capture the core principle of stimulus equivalence in the same way as matching printed words to actual objects does. These options may represent different types of learning or associations, but they do not illustrate the specific equivalence relationships that stimulus equivalence encompasses.
