Liking, familiarity, normality
For all study foods, participants rated liking (1 [not at all] -7 [very much]), and familiarity (’I would normally eat this type of food’; 1 [strongly disagree] – 7 [strongly agree]). Participants were also shown images of each portion for the portion-manipulated foods and asked how ‘normal’ it was (1 [not normal, it is far too small] – 7 [not normal, it is far too big]).
