Resumen
There are many ways in which a laboratory difference test differs from 'real life' discrimination of foods. One of these is the interval of time between tasting the two stimuli to be discriminated. To investigate this, Cubero et;al. (1995) investigated interstimulus delays of up to I min, for the same-different test, using a citrus flavored beverage as a medium. The present study extended this research by increasing the interstimulus delays up to I day. For judges unfamiliar with the stimuli, performance deteriorated as the time interval increased. For judges more familiar with the stimuli, performance deteriorated but not as much. The results were compatible with Cubero et al.'s hypothesis that different types of memory trace for the first (standard) stimulus were utilized for comparison with the second (comparison) stimulus. 14 1 1 18
