Work accomplished is described under the following headings 1 Psychophysical scaling. Transportation was used as a scaling method. By this criterion, the musical scale is better than the mel scale. Manitude judgments were analyzed into input and output components. 2 Perceptual grouping. The kinds of homogeneity that provide similarity grouping were investigated. Slope of elements is the highest order variable that gives decisive grouping. 3 Reference systems. The dependence of stimulus classification on orientational frames of reference was studied in a variety of ways. 4 Space perception. The Gestalt principle of Pragnanz is supported by this research. Perceived tridimensional orientation tends to that which is consistent with the simplest object. Author
