Intervention model description: Randomized controlled crossover study where participants were assigned to begin in the distracted or control condition. One week later, participants completed the opposite condition.
Primary purpose: PREVENTION

Brief summary: This study determined effects of a cognitive distraction on amount, preference, and memory of food consumed and perceptions of fullness, hunger, and enjoyment of food in a healthy young-adult population. A randomized controlled crossover study of 119 healthy adults, assigned to begin in either the distracted or control condition, was conducted.

Detailed description: Environmental distractions have been shown to affect eating patterns. Influences of food environments on consumption patterns and not simply food choices are becoming increasingly clear for their contributions to energy intake. Of particular interest is the presence of distraction. It has been postulated that when distracted, individuals are inclined to consumer more than when not distracted. However, how distraction and memory impact subsequent food choice and preference is less well known. A Rapid Visual Information Processing (RVIP) task was applied to distract individuals while eating; food intake and food behaviors were measured after RVIP distraction and compared to food intake and food behaviors without distraction in the same individuals.
