Final answer:
In classical counter conditioning, the conditioned stimulus must be presented before the unconditioned stimulus. This pairing should occur with a brief interval during the acquisition phase for effective association and response.
Step-by-step explanation:
In classical counter conditioning, the correct order of presentation is that the conditioned stimulus (CS) should be presented before the unconditioned stimulus (US). During this classical conditioning acquisition phase, the CS, which is originally neutral, is paired with the US until the CS alone evokes the conditioned response (CR).
This process requires careful attention to the timeline of events to understand the cause (US) and effect (CR) relationship. It's important that there is only a brief interval between the presentation of the CS and the US for effective conditioning; this interval often ranges from a few seconds up to several hours, depending on the specific conditioning scenario.
