Outcome measures
Primary outcome
Physiological parameters include changes in instantaneous heart rate,
electrodermal activity, skin temperature, and facial expressions as a result of
sensory-specific satiety. Behavioral parameters include changes in liking,
general and specific appetite, as a result of sensory-specific satiety.
Secondary outcome
Differences in fysiological and behavioral measures, between the (sweet versus
savory) eating conditions.
Background summary
Eating behavior is determined by many variables, including sensory processes
that influence the selection of foods and determine meal size. As a food is
consumed, its perceived pleasantness declines compared to that of other foods.
This phenomenon, referred to as sensory-specific satiety, contributes to the
termination of eating, along with other factors. Though this effect is
well-established, implicit responses may be better suited to provide more
insight in temporal development of sensory specific satiety and complementary
information to the preference scores for the test stimuli presented before and
after exposure.
Study objective
To investigate responses of the autonomic nervous system (ANS) and facial
expressions to sensory-specific satiety.
Study design
The study design is a within-subject intervention experiment. All participants
will visit four times, in which they will receive different meals (sweet,
savory) leading to sensory-specific satiety. Before, during and after the
meals, ANS responses, facial expressions and liking will be measured.
Intervention
various food products to be eaten ad libitum
Study burden and risks
Subjects will participate in four experimental sessions, each lasting between
45-60 minutes. Subjects will receive test meals and will be provided with
sensors fitted to their chest and non-dominant hand. Experiences so far
indicate that the sensors themselves are unlikely to cause discomfort. The risk
associated with participation is negligible. There will be no current
therapeutical/beneficial effects for the subjects.
