The taste of cutlery: how the taste of food is affected by the weight, size, shape, and colour of the cutlery used to eat it (2013, background): “Consumption behaviours can change with the shape of the glass [4,5], the size of the plateware [6-8], and the size of the cutlery with which a person eats [9,10].”
Slim by Design: Redirecting the Accidental Drivers of Mindless Overeating (2014, background): “Because of the Delboeuf illusion, the same amount of food seems smaller on larger plates or on plates with thin rims (McClain, et al. 2013) and this leads people to overserve on larger plates and underserve on smaller ones (van Ittersum & Wansink 2012).”
'Nudging' hotel guests to reduce food waste as a win-win environmental measure (2013, background): “In addition to the social cue it provides, larger plates might also contribute to people serving and consuming more food due to visual illusions that lead to biased perceptions of how much food is served or consumed (Ittersum and Wansink, 2012).”
