Final answer:
Alicia decided to buy the perfume after watching an ad featuring Emma Watson because she was persuaded by the use of advertising techniques that appealed to her senses and emotions.
Step-by-step explanation:
The ad's striking imagery, the allure of celebrity endorsement, the captivating music and the overall aesthetic of a beautiful location all play a role in persuading consumers. This approach is typical in the beauty industry, where advertisements often utilize visuals and scenarios that evoke a sense of glamour and aspiration, persuading customers like Alicia to associate these positive feelings with the product itself.
These tactics have been effectively encouraging people to buy perfumes, soaps, and other cosmetic products by creating desires that correlate with beauty and elegance, strongly influencing consumer behavior. The combination of these elements makes the product appear not only desirable but essential, often leading to a response like Alicia's.
Moreover, phrases like 'liquid music of her voice' or 'perfume while you may' from the provided references, enhance the idea of perfumes and cosmetics transcending mere functionality to become objects signifying luxury and transient beauty. Ads tend to suggest that these products can contribute to personal transformation or attainment of an idealized self.
