उत्तर
- Boy A's salivation response to the restaurant menu differs from Boy B's due to conditioned responses.
- When people have previously enjoyed excellent foods, their brains may correlate the sight or fragrance with the expectation of a tasty meal, causing salivation.
- Boy B's acquaintance with the menu items creates a conditioned reaction to salivate.
- Boy A's lack of prior taste associations with the menu items prevents him from salivating and experiencing the conditioned reflex.
