Quizplus · Accepted Answer

Garcia's experiment demonstrated that in situations where the conditioned response (avoiding a food or drink) is crucial for survival, the unconditioned stimulus (in this case, nausea) does not need to immediately follow the conditioned stimulus (the sweetened water). This finding challenged the previously held belief that the timing between the CS and US had to be very short for conditioning to occur.
