IAPS ratings on the IAPS arousal and valence scale for female subjects. Ratings are scored such that 9 represents a high rating on the dimension (high arousal, high pleasure), and 1 represents a low rating on each dimension (low arousal, low pleasure). Standard background pictures had a low arousal value; arousing background pictures had a high arousal value [24].
