What Do We Really Need? Goals and Values, Security, and the Perception of Consumer Necessity
研究了消费品从奢侈品变为必需品的感知现象，发现内在目标追求与必需品感知负相关，外在目标追求正相关，且必需品感知在焦虑依恋与物质主义之间起中介作用。
ABSTRACT There is a general trend for consumer goods considered luxuries to become thought of as necessities. Although the luxury/necessity distinction is central to the fields of marketing and economics, little research has examined the perception of necessity as a psychological phenomenon. Three studies examined the relationship of the perceived necessity of a variety of consumer goods to goals, values, and insecurity. In Study 1, the number of goods considered necessities as opposed to luxuries correlated negatively with intrinsic and positively with extrinsic goal pursuit. In Study 2, this pattern generalized to the distinction between needs and wants, the extent to which participants reported needing their possessions, and to materialistic values. In Study 3, the perception of necessity mediated the relationship between anxious attachment and materialism, suggesting that needing consumer products has in part a basis in interpersonal insecurity. In turn, it may facilitate materialistic consumption.
