Key research themes
1. How do environmental factors and consumption norms unconsciously influence the volume of food intake?
This theme investigates the subtle and often unmonitored environmental cues and contextual elements that lead to increased food consumption volume. It addresses how factors such as package size, plate shape, lighting, social setting, and food variety alter consumption norms and impair individuals' ability to monitor intake, thereby driving overconsumption without conscious awareness. Understanding these cognitive and perceptual mechanisms is crucial for developing interventions that target consumption volume reduction and addressing obesity.
2. What role does habit strength and automaticity play in daily food consumption and snacking behavior?
Research under this theme focuses on the cognitive and neurobiological mechanisms that characterize habits, specifically habitual food consumption and snacking. It addresses how repetitive behaviors in stable contexts create automatic responses that reduce conscious control over eating, thereby influencing energy intake patterns, choice of snacks, and challenges for intentional dietary changes. The relation between habit strength, motivation, and between-meal snacking is also examined to understand individual differences in consumption behavior.
3. How do social contexts, eating practices, and consumption habits mediate diet quality and food waste behaviors?
This theme explores the intersection of social, cultural, and habitual factors influencing food practices beyond physiological consumption. It includes analyses of social company during eating, timing and duration of meals, concurrent media consumption (e.g., TV viewing), and food waste behaviors such as reduction, reuse, and recycling. The theme captures how social environments, consumer habits, and attitudes toward food relate to overall diet quality and sustainable food use.
