Methods to Study Everyday Use of products in households: The Wageningen Mouthing Study as an Example

摘要

Several methods exist to study human behaviour in everyday life: e.g. an oral or written interview, measurement of physical variables and observation. All of them have their advan- tages and disadvantages, which are described in this paper. When a clear picture of actual human behaviour and information about an entire activity are required, for example to assess risks of exposure to chemical substances, it is best to use combination of available methods. In this way the advantages of all methods can be combined. This was done in the Wageningen Mouthing study of which some results are presented.
