Correlations between z-scores of kcal intake of foods included (exposed) and not included (non-exposed) in CET and within-session habituation (WSH) and between-session habituation (BSH) of eating desires, and expectancy violation among participants of four studies [72, 73, 74•, 75]

	WSH of eating desires n = 140	BSH of eating desires n = 94	Expectancy violation n = 150
z intake exposed fooda	− 0.05	− 0.08	− 0.18*
z intake non-exposed food2	0.02	− 0.06	− 0.12

In all studies [72, 73, 74•, 75], WSH was calculated subtracting the end eating desire from the session’s peak eating desire (measured on a 100 mm Visual Analogue Scale [VAS]), and, in case of multiple exposure sessions, the average was calculated. BSH was calculated for three studies (which included 2 or more exposure sessions) by subtracting peak desires in the last sessions from peak desires in the first session. Expectancy violation was calculated by subtracting post-intervention expectancies from pre-intervention expectancies (measured on 100 mm VAS); in studies where expectancies about eating specific foods were asked, scores were averaged. As expectancies were assessed using a 5-point scale in [73], scores were transformed (1 = 0; 2 = 25; 3 = 50; 4 = 75; 5 = 100)

*p < .05; sample sizes of each correlation vary due to measurement differences between studies

^aTo compare the intake during the taste test in all studies, z-scores were calculated. Some differences between studies are worth mentioning: general exposed foods were included in the taste tests described in [72, 73], while foods in [74•, 75] were personally selected. In [75], one general exposed food item was additionally included during the taste test, but no general non-exposed food item was included as comparison and therefore not included in the present investigation. Pure kcals were converted into z-scores for the data of [72, 74•, 75], while the intake in [73] was converted into a percentage of daily required energy intake for children, and then converted into z-scores
