Here, increased amplitude under no promotion might be more reflective of the typical N400 incongruity effect (cf. Figure 2a). The consumer compares the price to their internal reference price, which if rejected is reflected in an N400 mismatch effect. Thus, different naïve theories might be utilized when asked to evaluate a non-promoted versus promoted price. Put more plainly, to the extent that High MA (and Low) consumers can activate a semantic processing subroutine for price promotions this is inferred as beneficial and associated with increased purchasing. To the extent that High MA consumers have to activate a semantic processing subroutine under no promotions this is inferred as a detraction, which decreases the likelihood that the consumer will make a purchase
