Extraction of unconscious emotions while watching TV commercials

Our aim of this study is to examine whether there are emotional differences in TV commercials that consumers watch favorably/unfavorably, using an electroencephalogram (EEG) and a questionnaire. With the advance of marketing research, neuromarketing has attracted rising attention, which allows us to know consumers' unconscious emotions. Among a great number of neuromarketing researches, we focus on TV commercials, which are pervasive in our daily lives and which have great influence on society. Therefore, experiments are carried out with actual TV commercials created in Japan. We identify what kinds of emotions are correlated while consumers are watching their favorable/unfavorable TV commercials. Furthermore, as a long-term follow-up, we survey how many these TV commercials consumers keep in their memories even a month later from the experiment day. As a result, we confirmed that there were strong significant correlations between concentration and stress while watching favorable TV commercials. This tendency was not seen in the case of unfavorable TV commercials. Hence, different emotional states could interact one another depending on consumers' preferences of TV commercials. In addition, favorable TV commercials were more retained in consumers' memories. In this way, we investigate how TV commercials actually have effects on not only consumers' unconscious emotions but also their memories.
