Final answer:
The utilitarian aspect of an attitude object pertains to its practical functional benefits, related to the satisfaction and utility it provides, which aligns with the concept of the law of diminishing marginal utility.
Step-by-step explanation:
The utilitarian aspect of an attitude object, such as a consumer product, refers to the practical functional benefits it provides to the user. These benefits derive from the product's ability to satisfy specific needs or wants, representing its utility. For example, one of the main reasons people consume goods like food is due to the utility received from eating—such as the fulfillment of dietary needs and the pleasure from taste—which economists describe through concepts like law of diminishing marginal utility. This principle explains why the first few units of a good consumed may provide a greater utility than subsequent units, reflecting the consumer's change in the level of satisfaction gained.
