Scaling in psychology can be classified into two categories – psychophysical scaling and psychological scaling. Although psychological scaling had its origin in Fechner’s method of first choices and the work on colour preference, the major work in psychological scaling began in 1920’s in the context of attitude measurement. Bogardus Social Distance Scale (1925) is one of such first attempts. A major breakthrough in attitude scaling occurred when Thurstone developed his Law of Comparative Judgement (LCJ) and also proposed the three scaling methods- paired comparison, equal appearing intervals and successive intervals. In the paired comparison, every statement/stimulus is paired with every other statement/stimulus. The computational methods of paired comparison are most extensively developed, some of them using Thurston’s LCJ directly for this purpose. Such pairing of statements/stimuli is not involved in methods of Equal Appearing Intervals (EAI) and Successive Intervals (SI). Moreover, the distributions of the categories, assigned by the judges to each attitude statement in EAI and SI need not be normal; in fact the distributions for several statements are skewed. This situation requires some computational precautions. Moreover, the method of successive intervals was computationally quite laborious in pre-computer era and hence it was not so popular. In the classical scaling tradition, Guttmann developed the scalogram technique and Edwards developed the scale discrimination technique. Likert’s development of summated ratings represent an important landmark in attitude measurement. It follows the traditional psychometric model. Aiken and Groth -Marnatt (2009) concluded that other scaling techniques, less frequently used for attitude measurement, include Osgood’s semantic differential, Q-sort, expectancy value rating, magnitude estimation, multidimensional scaling etc.
