“…Arousal has been defined as an unconscious, instinctive response, a motivational state ranging from a continuum of drowsiness, in which one feels soporific, to extreme alertness, in which one feels energized (Mandler, 1982; Muro & Murray, 2012; Noseworthy, Muro, & Murray, 2014). Arousal can function as an additive effect derived from an object's psychophysical properties (e.g., intensity, pitch, hue, brightness), novelty properties and survival properties (e.g., health, threats, and fear; Batra & Ghoshal, 2018). As an important and common psychophysical property, color have a significant influence on consumers' arousal level, the diversity and complexity of color can also lead to different arousal levels (Berlyne & Daniel, 1960; Valdez & Mehrabian, 1994).…”
