• 1 other identifier: liguori
• Study Type: interventional
• Target: 119
• Locations: 1 country

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.

Study Arms (2)

Distraction

EXPERIMENTAL

Distraction during eating using the Rapid Visual Information Processing task as the distraction

Behavioral: Rapid Visual Information Processing task

Control

PLACEBO COMPARATOR

No distraction during eating

Behavioral: None or Control condition

Interventions

Rapid Visual Information Processing task BEHAVIORAL

A series of numbers appeared on a computer screen at a rate of one per minute. Each participant was required to identify any series of three consecutive odd or even numbers by hitting the space bar on the keyboard. The task lasted 15 minutes and included a 1-minute practice session before food being served. Participants were instructed to eat at will while completing the computer task.

Distraction

None or Control condition BEHAVIORAL

Participant were instructed to eat at will during a 15-minute duration.

Control
