Perceptual centres for Dutch digits

In two experiments, analogous to those reported by Marcus (1976) with English words and subjects, we determined the psychological moment of occurrence (p-centre) of Dutch digit names. In the first experiment we determined the p-centres for the digits 1 through 10 and compared the empirical results with values calculated from the formula that Marcus defines over the acoustic characteristics of stimulus words. We found good agreement between empirical and predicted values. In a second experiment we studied the effect of cycle time and repeated measurement on perceptual centres. The results confirm the independence of the p-centre phenomenon from practice and periodicity. A comparison of ‘identical’ and ‘non-identical’ stimulus pairs shows that larger variances are associated with the former condition.
