Abstract : 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)
