Outcome measures
Primary outcome
Main study parameters/endpoints: Our main outcome measurement is 1) the change
in brain reward response to sight of single breads presented with and without
aroma, 2) bread choice behavior with and without aroma and with price
information.
Secondary outcome
1) The difference on explicit liking (ratings on VAS), explicit wanting
(ratings on VAS), implicit wanting (reaction time in food choice), and food
preference (frequency) as a result of aroma and/or price.
2) whether individual differences in reward measured in the cue study affect
individual choice behaviour in the choice study.
Background summary
Whole grain bread has various health benefits over wheat or refined wheat
bread. Despite these known health effects, whole grain bread is not the first
choice for the majority of people. This is thought to be due to the relatively
unfavourable image of bread.
Study objective
Objective: Bread aroma may increase consumer*s motivation to buy bread.
Motivation for products is hard to measure reliably in real life settings like
a supermarket, but can be studied via brain imaging. In this project, brain
imaging is used to elucidate how bread aroma affects consumer motivation for
and acceptance of healthier breads.
Study design
Study design: In a within-participant study design participants will be exposed
to images of either single breads (preference or cue task) or combinations of
assorted breads (choice task). During the cue and choice tasks aroma stimuli
will be presented using a computer-controlled fMRI-compatible
olfactometer.Changes of reward responses in the brain will be measured by using
functional magnetic resonance imaging (fMRI) when exposed to sight with and
without aroma of single breads, including whole grain bread. In the choice
task, bread selection and selection time, will be recorded, when exposed to
sight, aroma, and price of assorted breads. Bread preference will be also be
measured by subjective ratings. Cookies will be used as an indulgent control
stimulus that is expected to trigger reward responses.

Study burden and risks
Nature and extent of the burden and risks associated with participation,
benefit and group relatedness: The study duration will consist of three
1/1,5-hr periods separated by one week. In the first period they will visit the
Restaurant of the Future for MRI training in the dummy scanner and to fill out
questionnaires. In the second period participants will visit the fMRI facility
in Ede (Hospital Gelderse Vallei) to undergo fMRI measurements. In the third
period they will visit the Restaurant of the Future for food choice
measurements. The study is non-therapeutic to the participants. The risk
associated with participation is negligible.
