Answer:
Not want to eat it and will be turned off by the look of the cake and the smell of it.
Step-by-step explanation:
In classical conditioning, an individual associates an stimulus with an specific response. This association makes the individual have this response in presence of the stimulus, which means that this response is a learned behavior based on previous experiences.
In this example, Riley ate too much chocolate cake (stimulus) and was sick all night (response). Now, if classical conditioned occurred and he associated the cake with being sick, it means that this response will be triggered in presence of the stimulus now so if Riley sees cake today he will likely remember how it got him sick last time and he will not want to eat it and will be turned off by the look of the cake and the smell of it.
