SENSATION SCALES IN THE SIZE-WEIGHT ILLUSION

S joberg , L. Sensation scales in the size-weight illusion. Scand. J. Psychol ., 1969, 10 , 109–112.-The subjects gave magnitude estimations of heaviness of a set of cylinders varying simultaneously in weight and height. The size-weight illusion could be well described by a simple model assuming heaviness to be inversely proportional to a sensation scale of size and directly proportional to a sensation scale of weight. The scale parameters corresponding to weight were a positively accelerated function of weight while the corresponding function for size was negatively accelerated.
