Resumen de Popcorn in the cinema: : Oral interference sabotages advertising effects
Sascha Topolinski, Sandy Lindner, Anna Freudenberg
One important psychological mechanism of advertising is mere exposure inducing positive attitudes towards brands. Recent basic research has shown that the underlying mechanism of mere exposure for words, in turn, is the training of subvocal pronunciation, which can be obstructed by oral motor-interference. Commercials for foreign brands were shown in cinema sessions while participants either ate popcorn, chewed gum (oral interference) or consumed a single sugar cube (control). Brand choice and brand attitudes were assessed one week later. While control participants more likely spent money (Experiment 1, N = 188) and exhibited higher preference and physiological responses (Experiment 2, N = 96) for advertised than for novel brands, participants who had consumed popcorn or gum during commercials showed no advertising effects. It is concluded that advertising might be futile under ecological situations involving oral interference, such as snacking or talking, which ironically is often the case.
