摘要:
Researchers have investigated a number of different antecedents and consequents of attitude toward the ad (Aad), including ad cognition (Cad), brand cognition (Cb), and attitude toward the brand (Ab). The Dual Mediation model (MacKenzie, Lutz, and Belch, 1986), which specifies hypothesized interrelationships among these constructs, has been well supported in previous Aad research. The authors extend this model to include ad affective responses (Aff), a construct that has received considerable attention in the literature (MacKenzie and Lutz, 1989), and three additional model paths (Aff-->Cad, Aff-->Aad, and Cad-->Cb). The strength of the various causal links in the extended version of the Dual Mediation model (DMM) are examined across three common types of broadcast media viewing situations: (1) pretest;(2) normal/routine;and (3) buying/decision making. Results indicate a variation in path strength depending upon viewing context, providing theoretical support for predictions regarding the nature of processing inherent in ad and brand attitude formation.
