Final answer:
Piqueras-Fiszman and Spence (2012) studied how various factors such as tableware influence the perception of taste in food and drink.
Step-by-step explanation:
Piqueras-Fiszman and Spence (2012) investigated how the perception of taste is affected by certain variables. Specifically, their studies often focused on factors such as the color, weight, and shape of tableware and how these variables influence the perceived taste and enjoyment of foods and beverages, such as hot chocolate and yogurt. In a broader context, their research falls within the field of gastrophysics, which examines the multitude of factors that can influence an individual's experience of consuming food and drink beyond the food item itself.
