What is an example of an instrumental motive in consumer behavior?

The correct choice exemplifies instrumental motives, which are driven by practical benefits or the desire to achieve specific outcomes. In this case, buying a trendy outfit to impress friends reflects a clear instrumental motive, as the consumer is motivated by the social reward of gaining acceptance or admiration from their peers. This behavior is not merely about the outfit itself, but rather the social implications and the potential improvements in social standing that come with it.

The other options demonstrate different types of motives that aren't primarily instrumental. For instance, reading a book for enjoyment represents a hedonic motive, where the primary goal is pleasure and personal enjoyment rather than a direct practical outcome. Similarly, watching a movie for entertainment also aligns with hedonic motives focused on leisure and enjoyment. Learning a new skill for personal satisfaction can be seen as an intrinsic motivation aimed at self-improvement, which does not focus on external rewards or practical outcomes like social acceptance. Thus, the act of purchasing a trendy outfit is distinctly aligned with an instrumental motive due to its focus on attaining social benefits.
