It is hypothesized that participants who received information about social modeling effects in the intervention group consume less (snack) food compared to participants in the control group.

Uitkomstmaten
Primaire uitkomstmaten
To measure social influence on food intake in the intervention group compared to the control group:<br>
1. Snack food intake (kcal);<br>
2. Micro-imitation: Video coding of food picking movements of the instructed peer and the participant.
Achtergrond van het onderzoek
People are found to follow the food intake of a peer and eat more when others do. In this study it is investigated whether children can be made aware of these social modeling effects during a short intervention at school and are less influenced by the food intake of a peer (compared to the control group).
During the intervention, we explain social modeling effects and imitation to the children. On this day, the majority of the control group is tested. On the next day, the intervention group is tested. By means of social modeling experiments, we compare the food intake of the intervention group to the control group which has received no information about social modeling effects and imitation. In addition, we coded the intake movements of the participant and peer dyads to investigate micro-imitation.
Doel van het onderzoek
It is hypothesized that participants who received information about social modeling effects in the intervention group consume less (snack) food compared to participants in the control group.
Onderzoeksopzet
Pilot study: October - December 2011;
Intervention: February - June 2012.
Onderzoeksproduct en/of interventie
People are found to follow the food intake of a peer and eat more when others do. In this study it is investigated whether children can be made aware of these social modeling effects during a 10-minute intervention at school and are less influenced by the food intake of a peer (compared to the control group).
During the intervention, the children are told about social modeling effects and imitation by means of pictures of monkey's and humans who model body postures, a little movie clip in which they see children model the food intake of some one else and an exercise in which children have to model an experimenter's food choice and intake.
One day after the intervention, social modeling experiments are conducted. In a social modeling experiment, a naive participant is paired with an instructed peer. The peer is instructed to eat a certain amount of test food. During the social modeling experiment, the children are video taped.
We compare the intervention group to the control group which has received no information about social modeling effects and imitation.
