Demographic characteristics of the sample.

Each dot represents an IAPS or an OLAF image as a function of its mean pleasure (y axis) and arousal (x axis) ratings.

SAM ratings across IAPS and OLAF picture categories for pleasure (2a), arousal (2b), dominance (2c), and food cravings (2d).
Erotica, neutral objects, and mutilations prompted the typical patterns in the dimensions of pleasure, arousal, and dominance. For foods, pleasure and arousal jointly provided the more reliable description of the emotional impact of specific food categories, distinguishing more clearly than the other dimensions between sweet and savory high-calorie foods and low-calorie fruits and vegetables. On the contrary, as in our previous work [17], food cravings were less capable of pinpointing the emotional impact of different food categories.
