The examples provided are showcasing operant and classical conditioning. Javier's tale and George's slot machine behavior represent operant conditioning, where actions are influenced by rewards or punishments. Sue's anticipation and Leah's physical reactions to stimuli are instances of classical conditioning, where a neutral stimulus becomes associated with a certain response.
In the scenarios provided, we are looking at examples of classical conditioning and operant conditioning. The first example, where Javier's parents promised him a new car if he made straight A's, is an example of operant conditioning because he is being promised a reward for a certain behavior, which is getting good grades. In the second example, George playing the slot machine and continuing to play because of the rewards is another example of operant conditioning, where behavior is influenced by the consequences of actions.
The third example of Sue's stomach growling when she hears the doorbell, anticipating her favorite latte and doughnut, is an instance of classical conditioning, as the doorbell has become a conditioned stimulus that triggers a conditioned response (stomach growling). Lastly, Leadfoot Leah experiencing physical symptoms when she sees a police car or drives through a neighborhood where she's received tickets is also classical conditioning because she has associated these stimuli with the unpleasant experience of getting a ticket, even though the actual receiving of a ticket does not follow.
