Involuntary Attention and Physiological Arousal Evoked by Structural Features and Emotional Content in TV Commercials

Structural features of television elicit involuntary physiological attentional responses in viewers. Mild emotional content in televised messages intensifies these responses, possibly through mediation of emotion-elicited arousal, which was also demonstrated. Heart rate data were collected and analyzed using novel techniques to show both short-term attentional responses and longer term arousal in subjects viewing commercial messages.
