A brief three-item measure of current state arousal, capturing the degree to which a person feels physiologically activated versus calm and low-energy. Originally developed to assess incidental arousal induced by emotional video stimuli and its downstream effects on information sharing behaviour. Subsequently adopted widely in consumer research to measure arousal induced by product, advertising, or environmental stimuli.
