Note: This course has a maximum number of participants (and has on top of that reserved places for new MSc students). The deadline for registration is one week earlier than usual. See Academic Year (http://www.wur.nl/en/Education-Programmes/Current-Students/Agenda-Calendar-Academic-Year.htm) -> Registration for Courses.
Sensory science is an expanding field of research. During this course, an introduction will be given to the field of sensory science. The different aspects of sensory science as well as the relationships between these aspects will be discussed and presented. Several (guest) lectures are given on the basic theoretical knowledge of sensory science with a focus on human research. Classical and more novel sensory methodology and physiology of the senses are the basis of this course, which will be studied in-depth. Additionally, basic experimental psychology, behavioral observation and different factors that can influence sensation & perception (e.g. context, learning) will be discussed to show the development of the field, as well as statistical methods to analyse sensory data. Besides following lectures, the students will perform a classical sensory test on their own, within a specific food category. They will analyse and present the data with simple as well as more advanced statistics (such as mixed models, PCA) and descriptive plots, and write a scientific report about the results with their own practical group, and present it as well. The students will have an excursion to the Restaurant of the Future to show our the state-of-the-art facilities for sensory research facilities (e.g. behavioral observation).
The topics covered by this course are:
- classical and advanced sensory methodology: discrimination, thresholds, descriptive, preference and affective tests (in-depth); temporal dynamic methods; psychophysics (in-depth),
- sensory perception and evaluation: physiology, anatomy & functions of the senses (in-depth), behavioral observation, context & bias in sensory studies;
- sensory analyses: sensometrics, interpretation and presentation of sensory research data.
After successful completion of this course students are expected to be able to:
- explain and illustrate the basic theoretical principles of sensory science;
- select and apply the appropriate sensory methods with respect to the research question;
- explain and implement the function and physiology of the different flavor-related senses , and how they can interact;
- prepare and execute a sensory test in a scientific way;
- analyse and interpret sensory data correctly;
- design and setup a sensory experiment based on a self-generated research question;
- critically reflect and discuss sensory literature.
- follow lectures on sensory science theory;
- literature study;
- learn from knowledge clips;
- engage in e-modules;
- (PC) tutorials;
- group work (practical sensory testing; setup, perform and analyze own descriptive sensory analysis);
- tour through human (observational) behavior research facilities
- writing a scientific report
Final grade will be based upon a written examination (2/3 of the grade; open questions and multiple choice) as well as the group work (1/3 of the grade; based on research proposal, report and presentation). Each component needs a minimum mark of 5.50 to pass. The mark for the group work is valid for 2 academic years.
