Cognitive representation of the comprehension test of safety warnings using multivariate methods

Abstract

This paper presents a multivariate method to assess the comprehension of safety signs. The proposed method uses the MDS and Procrustes, to obtain a consensus perceptual map. The results show that the map allowed discriminating signs with high levels of comprehension from others. The safety signs have no statistical difference as depicted by Bootstrap Analysis. © 2012 - IOS Press and the authors. All rights reserved.
