["While in general arousal increases with positive or negative valence (a so-called V-shape relation), there are large differences among individuals in how these two fundamental dimensions of affect are related in people's experience. In two studies, we examined two possible sources of this variation: personality and culture.", 'In Study 1, participants recalled a recent event that was characterised by high or low valence or arousal and reported on their feelings, and reported on their personality in terms of the Five-Factor Model. In Study 2, participants from Canada, China/Hong Kong, Japan, Korea, and Spain reported on their feelings in a thin slice of time and on their personality.', 'In Study 1, we replicated the V-shape as characterising the relation between valence and arousal, and identified personality correlates of experiencing particular valence-arousal combinations. In Study 2, we documented how the V-shaped relation varied as a function of western versus eastern cultural background and again personality.'] Does the relation between valence and arousal in subjective experience vary with personality and culture?
