Yvonne's aversion to yogurt developed after just one exposure to it followed by illness, demonstrating that classical conditioning can occur with just a single pairing of a conditioned stimulus (yogurt) and an unconditioned stimulus (illness), even if there is a long interval between the CS and the US. This is unique because classical conditioning often requires multiple pairings, especially when there's a significant delay between the CS and US.
