Exploring the spatial mental associations of distinct food types

Abstract

Previous research explored the spatial representations of healthy low -calorie and unhealthy high -calorie food items, revealing an association of healthy low -calorie food with left and top sides, and unhealthy/high-calorie food with right and top sides. This association, namely side bias, was limited to these specific categories leaving the representations of healthy high -calorie and unhealthy low -calorie food categories yet to be explored. Present study was designed to examine the spatial representation of four food categories (unhealthy low -calorie, unhealthy high -calorie, healthy low -calorie, healthy high -calorie) using a computerized food placement task. In Experiment 1, participants placed four food items from different categories into eight locations. In Experiment 2, identical task was used with the addition of centrally presented anchor food item to investigate the mental representation of food items in relation to each other. The frequency of placing food items in specific spatial locations were measured. The results of Experiment 1 provided partial support for side bias. However, the use of anchor items in Experiment 2 provided compelling evidence for vertical side bias, demonstrating consistent pattern of placing healthy foods on the upper sides and unhealthy foods on the lower sides. In both experiments, real -life food choices were examined to investigate whether the high -calorie bias would be observed in actual food choice behavior. The results from both experiments indicated strong preference to select high -calorie foods, supporting high -calorie bias. Overall, this study extends the evidence on the spatial representations of distinct food categories.
