Abstract
In the sensory evaluation of foods and beverages the Triangular Method or Triangle Test is frequently used to study differences between samples (of stimuli). Because of its statistical character the method does not prescribe a particular judgemental procedure to be followed when it is applied. For this reason situational variables have been reported to influence results obtained by this method (Amerine et al., 1963). In the present experiment, in the olfactory modality, the influence of inter-stimulus interval duration within a triangle was investigated. Over the range studied this variable was found to have no effect on the subjects' performance. A positional bias in favour of the middle stimulus has been reported in literature (Harrison and Elder, 1950). The results obtained did not support this observation. On the contrary a bias towards the left or right sample was only found when discrimination was impossible.
