Which conditioning procedure involves presenting CS after a time gap before US, less effective than delayed conditioning?

• A. Simultaneous Conditioning
• B. Second-Order Conditioning
• C. Trace Conditioning
• D. Respondent Acquisition

Answer: (C)

In this type of Pavlovian learning, the timing between the conditioned stimulus (CS) and the unconditioned stimulus (US) is what guides how strong the association becomes. In trace conditioning, the CS is presented and then, after a brief gap, the US is presented. That gap means the animal must maintain a memory trace of the CS across the interval and then link it to the US, which is more demanding cognitively. Because the CS no longer overlaps with the US, the predictive connection is weaker, so learning tends to be slower and the conditioned response is less robust than in delayed conditioning, where the CS and US occur together or with the CS continuing up to the moment the US is delivered. Other patterns differ in timing: simultaneous conditioning pairs CS and US at the same time, which provides little predictive advantage; second-order conditioning uses a previously conditioned CS to pair with a new one, not about the CS–US gap; and respondent acquisition is the general process of learning the association, not a specific timing arrangement.
