Stimuli that function as reinforcers without prior learning are called what?

• A. Conditioned reinforcers
• B. Unconditioned reinforcers
• C. Positive reinforcement
• D. Aversive

Answer: (B)

Stimuli that reinforce behavior without any prior learning are unconditioned reinforcers. These are also called primary reinforcers because their reinforcing value is innate and tied to biological needs, so they naturally strengthen behavior. Examples include food when hungry, water, warmth, or relief from pain—things the organism naturally seeks. In contrast, stimuli that become reinforcing only after learning (through association with a primary reinforcer) are conditioned reinforcers, like money or praise. Positive reinforcement describes the process of presenting a reinforcer to increase behavior, not a type of reinforcer itself, and an aversive stimulus is typically something unpleasant that motivates avoidance or punishment rather than reinforcement.
