In real life, listening to music may be associated with an eyes-closed or eyes-open state. The effect of eye state on listeners’ reaction to music has attracted some attention, but its influence on brain activity has not been fully investigated. The present study aimed to evaluate the electroencephalographic (EEG) markers for the emotional valence of music in different eye states. Thirty participants listened to musical excerpts with different emotional content in the eyes-closed and eyes-open states. The results showed that participants (...) rated the music as more pleasant or with more positive valence under an eyes-open state. In addition, we found that the alpha asymmetry indices calculated on the parietal and temporal sites reflected emotion valence in the eyes-closed and eyes-open states, respectively. The theta power in the frontal area significantly increased while listening to emotional-positive music compared to emotional-negative music under the eyes-closed condition. These effects of eye states on EEG markers are discussed in terms of brain mechanisms underlying attention and emotion. (shrink)

Emerging markets are a growing force, and the resulting increase in wealth—especially among the middle class—promotes conspicuous consumption with potentially negative impacts for societal and environmental well-being. Efforts to encourage ethical consumer behavior in emerging markets often meet various forms of consumer resistance. One reason that ethical consumption may suffer in emerging markets is because consumers have difficulty considering ethical other-focused attributes, such as Fair Trade or eco-friendly options, especially if those attributes do not directly benefit the self. Our research (...) demonstrates a simple way to encourage more ethical consumption in emerging markets, without economic incentives. In particular, when consumers see narrow (vs. broad) product categories, they are more likely to incorporate both salient (self-focused) and non-salient (other-focused) attributes into their decision. Thus, narrow product categories encourage consumers to consider ethical attributes to a greater extent than they normally would. This finding holds in private settings, across various product categories (i.e., coffee, tea, juice) and contexts (i.e., online and in the field), and in different emerging markets (e.g., India, South Africa, and Iran).
