Abstract : In a series of Titchener illusion figures, control subjects were asked to report the larger - center or surrounding - circles when the ratio of surrounding to center circle diameter varied, in .05 steps, from .75 to 1.25 across series members. Experimental subjects judged these series members, alternated with a stimulus configuration, in which the ratio of diameters was either .20 or 1.80. In both experimental groups, shifts in center-surrounding circle PSE and changes in judgments of series members were consistent with predictions drawn from the pooling model of AL theory. (Author)
