Question

Once simon had a big. Bowl of pasta form his residence cafe and accidentally washed it down with some expired milk he spent the rest of the day sick in the bathroom, and now whenever he walks by the pasta stand in the cafe and gets a big whiff of the cooking he starts to feel a bit queasy. What are the US and the CS in this scenario.

Answer 1

In Simon's scenario, the expired milk is the unconditioned stimulus (US) that naturally caused sickness, and the smell of pasta has become the conditioned stimulus (CS) that now triggers queasiness after being associated with the negative experience of sickness.

Step-by-step explanation:

The scenario you've described involves a classic example of classical conditioning, which is a learning process that occurs when two stimuli are repeatedly paired together. In Simon's case, the unconditioned stimulus (US) is the expired milk, which naturally caused him to feel sick without any prior learning - this reaction is an unconditioned response (UR). The conditioned stimulus (CS) is the smell of the pasta from the residence cafe, which, after being associated with getting sick from the expired milk, now triggers a conditioned response (CR) of feeling queasy whenever Simon smells it. The CS was originally a neutral stimulus (NS) that didn't elicit a queasy response until paired with the US.
