Stimulus characteristics taken from Blechert et al.’s (2014) database.

FOOD CATEGORIES	TOTAL CALORIES	VALENCE RATINGS	OBJECT SIZE	BRIGHTNESS	CONTRAST	COMPLEXITY
High Calorie/High Valence	490.52	56.51	.325	37.52	56.61	.087
High Calorie/Neutral Valence	490.26	41.04	.326	36.48	50.82	.082
Low Calorie/High Valence	71.47	62.95	.311	34.29	49.13	.077
Low Calorie/Neutral Valence	95.52	43.74	.311	29.43	53.77	.088

Note: Total calorie values expressed in Kcal, valence ratings from 1 (very low) to 100 (very high), object size (the proportion of non-white pixels relative to total number of pixels), brightness (the luminance of all non-white pixels of the grey-scale image and the white background), contrast (the SD of luminance across all non-white pixels of the gray-scale image), and complexity (for definition please see Blechert et al., 2014).
