“…Some researchers have examined aspects of the consumer (e.g., involvement; Swinyard, 1993), whereas others have focused on the effects of social factors, such as reference groups, on consumer choice (e.g., White & Dahl, 2006). Some researchers have focused on the distinction between explicit and implicit consumer preferences and how these preferences interact to influence consumer choice (e.g., Friese, Wanke, & Plessner, 2006) or on the relative impact of affective versus cognitive aspects of consumer preferences on consumer choice (e.g., Scarabis, Florack, & Gosejohann, 2006). Last, researchers have drawn on dominant models of the attitude-behavior relationship, namely the theory of planned behavior (TPB; Ajzen, 1985), to explain consumer behavior.…”
