Abstract

This study investigated preschool children's categorization and risk perception of products with ambiguous product characteristics (e.g., food-like packaging). These characteristics make it difficult for preschool children to categorize household chemicals correctly. This, therefore, increases the risk of unintentional poisoning. We hypothesized that ambiguity arises from different product characteristics, such as the type of packaging, the products' scent, or the packaging's color and transparency. In four behavioral tasks, N = 108 preschool children (M = 43 months, SD = 3) categorized different products and household chemicals with various types of packaging, colors, and scents. Individually wrapped dishwasher tablets were more likely to be categorized as edible than unwrapped ones. Furthermore, children who had interacted with any type of dishwasher tablet in the last 6 months performed better in identifying dishwasher tablets, regardless of packaging type. Household chemicals with a fruity scent were more likely to be categorized as drinkable than those with a chlorine scent. Finally, the children considered black bottles more dangerous and preferred them less than bottles of a different color. In contrast, bottle transparency generally did not seem to affect risk perception and preference. These findings confirm that ambiguous product characteristics influence children's categorization of unknown products and, thus, their risk perception and decision-making. Manufacturers and caregivers are advised to reduce the ambiguity of household chemicals by designing more neutral product packaging and choosing products with more neutral elements, respectively.
