consumed. If this emerging tendency of increased awareness of food qualities con-
tinues, then the validity of the proposed methodology will indeed have a positive
effect on both the companies' productivity, as well as positive effect on the health
of the population.
3.2.2 Psychology Perception
Perception is one of the oldest fields in psychology. The Weber-Fechner law in psy-
chology originated in the middle of the 19th century. Also the recent and more flex-
ible Stevens law, from the 1950's, has been frequently used. Both laws are mainly
founded on experiments, where two stimuli are given and a person is tested to
find out whether the intensity between the stimuli is noticed. The theories, which
quantify the relationship between the intensity of physical stimuli and their per-
ceptual effects, for example, in perception of temperature, moisture and comfort
in clothing, Li, (2005). The human perception is often related in the literature as
perception, when comprising both social and medical/psychological aspects. The
research models are often related back to Gestalt theory, Palmer (1990), and they
still have an extensive impact on the thinking around human perception.
In order to receive information from the environment we are equipped with
sense organs, e.g., eyes, ears and a nose. Each sense organ is part of the sensory
perception system, which receives sensory inputs and transmits sensory informa-
tion to the brain. A particular problem for psychologists is to explain the process,
by which the physical energy received by senseorgansformsthebasisofpercep-
tual experience. Sensory inputs organisation are obviously converted into percep-
tions of desks and computers, flowers and buildings, cars and planes; into sights,
sounds, smells, taste and touch experiences. The field of visual perception is fur-
ther presented in Gibson (1987).
