Which conditioning procedure presents the CS and US at the same moment?

Which conditioning procedure presents the CS and US at the same moment?

• A. Trace Conditioning
• B. Phylogenetic
• C. Simultaneous Conditioning
• D. Respondent Acquisition

Answer: (C)

Simultaneous conditioning is when the conditioned stimulus and the unconditioned stimulus begin at the same moment and are presented together. This creates perfect temporal contiguity between the two events, so the CS is a direct, immediate signal that the US is occurring. The strong, shared onset makes the association easy to learn because there’s no gap or delay to disrupt the predictive link. Trace conditioning would involve a gap between the CS and US, weakening the prediction since the US doesn’t occur until after a pause. Phylogenetic refers to evolutionary aspects of behavior, not a conditioning procedure. Respondent acquisition describes the overall process of forming a conditioned response, not the timing of CS and US.
