Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study examined the effect of adults' facial expressions (FEs) whilst eating raw broccoli on children's acceptance and intake of a typically less preferred vegetable. Investigating others' FEs in isolation (e.g., without statements about food tastiness) will improve understanding of the role of FEs in modelling of eating and contribute to developing strategies to help children learn pleasure from nutritious foods. Based on previous literature, it was hypothesised that children's acceptance (willingness to try, and frequency of taste exposures) and intake of raw broccoli would be higher after exposure to models eating raw broccoli with positive FEs, compared to models consuming raw broccoli with neutral FEs, or a non-food control video.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Research has shown that seeing positive facial expressions towards food are effective for increasing children's desire to eat foods rated as disliked. However, the effect of adults' positive facial expressions whilst eating a raw vegetable on children's acceptance and consumption of nutritious foods that are less preferred (e.g., vegetables) remains to be established. This study examined the effect of unfamiliar adult models' facial expressions eating raw broccoli on children's acceptance and consumption of raw broccoli. Children aged 4-6-year-olds were randomised to watch a video of unfamiliar adult models eating raw broccoli with a positive or neutral facial expression, or a non-food control video. Children's acceptance (willingness to try and frequency of taste exposures) and consumption of raw broccoli was assessed. Data about parent and child characteristics was provided by parents.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Positive Condition

Children were exposed to a video of adult models eating a single piece of raw broccoli whilst showing a positive facial expression (positive video)

Group Type EXPERIMENTAL

Facial expression video

Intervention Type BEHAVIORAL

Children are randomly allocated to one of three conditions: positive, neutral or no-food control, where they will watch either a positive, neutral, or no-food control video.

Neutral Condition

Children were exposed to a video of adult models eating a single piece of raw broccoli whilst showing a neutral facial expression (neutral video)

Group Type EXPERIMENTAL

Facial expression video

Intervention Type BEHAVIORAL

Children are randomly allocated to one of three conditions: positive, neutral or no-food control, where they will watch either a positive, neutral, or no-food control video.

No-Food Control Condition

Children were exposed to a video of adult models putting pens away whilst showing a neutral facial expression (no-food control video)

Group Type EXPERIMENTAL

Facial expression video

Intervention Type BEHAVIORAL

Children are randomly allocated to one of three conditions: positive, neutral or no-food control, where they will watch either a positive, neutral, or no-food control video.
