Though
Sensometticians come from many backgrounds, they al1 share an interest in models and techniques that can be applied to data from sensory and consumer studies. Sensometricians not only have very different backgrounds but work at different levels (nominal, not ordinal!) of the metrics-part of sensometrics. The discussion between workers at these levels is thought to be one of the most fertile activities of the sensometrics group. The levels interact when, for example, statisticians start developing new statistical methods to the specifications of a food-technologist to solve her/his problems. Or a worker from a biological background may suggest data-analytical models to the sensory psychologist that she/he never thought about before, and, of course, vice-versa. The first meeting was organised around the theme Homogrneity and heteqrneity in sensory and wnsumers&ce This theme was chosen because it is relevant to sensory research, consumer research and also certain types of marketing research. Heterogeneity is recognised to very different extents by these types of research; some ignore it, others capita& on it. The meeting consisted of talks from invited speakers, short presentations and discussions. The following talks were presented:
Some of tbe more prominent points raised in the discussions were: Checking assessors’ heterogeneity/ homogeneity, and the use of experimental designs. One of the results of the meeting was the genera1 understanding that experimental design can be a very important tool for sensometrics. Sensory analysis and consumer studies have properties that result in the need for quite specific designs, sometimes of great complexity. Because of the importante of this topic, it was decided to make it the theme for the second meeting, planned to be held in 1994. This ‘Second Sensomenics Meeting’ wil1 be held 14-16 September 1994, in Edinburgh, UK, and wil1 be organised by Tony Hunter from SASS. The theme of the meeting is Experimental Design in Sensoyy and Consumer Science. Information can be obtained f%om Dr E. A. Hunter, ‘Second Sensometrics Meeting’, SASS, The University of Edinburgh, Edinburgh EH9 3JZ, United Kingdom.
