Final answer:
Razran's study revealed that eating in a pleasant environment can make individuals more susceptible to social influences, a phenomenon known as Gastronomic Persuasion.
Step-by-step explanation:
Razran found that people exhibited more positive attitudes to social influence attempts while they were eating. He termed this phenomenon Gastronomic Persuasion. Eating can affect one's mood and receptivity to new information, which can be an important factor in social psychology. When individuals dine in pleasant environments with good company, they can be more open to social influences and persuasion. Aligning with Pavlov's classical conditioning, this can also be related to how environments and actions associated with positive experiences, like eating, can influence behaviors and attitudes.
