Reliability of Coordinates Obtained by MINISSA Concerning the Order of Presented Stimuli

In this work we study the stability of similarity judgements of sentences in regard to the presentation order of stimuli through MINISSA(Michigan–Israel–Nijmegen Integrated Smallest Space Analysis),which allows a Multidimensional Scaling with a triangular matrixof global similarity indices. Two forms of the same questionnaireby inverting the order of presentation of all possible unidirectionalcomparisons were applied. Results indicate that both forms areequivalent with similar structures and a high correlation coefficientbetween the judgements. We conclude a high stability of the usedprocedure. Furthermore, in comparison with a previous study, itcould be shown that the stability of solutions obtained by MINISSAis equivalent to that obtained by INDSCAL (INdividual DifferencesSCALing) which is not able to handle so many data as MINISSA.
