Tachistoscopic Versus Free Inspection Presentation of the Müller-Lyer Illusion

This study was designed as an attempt to extend Schneider and Shiffrin's (1977) automatic versus controlled processing distinction into the area of visual perception. Hasher and Zacks (1979) proposed a continuum of automatic processes, with processes which encode the fundamental aspects of the flow of information as the anchor of the continuum. They presented evidence that depressed people perform more poorly than nondepressed on effortful (controlled) memory tasks, but not on automatic tasks. Tachistoscopic and free inspection presentation of Piaget's (1961/1969) primary geometric illusions meet two of Hasher and Zack's criteria for automatic and effortful tasks, respectively. Consequently, multiple regression techniques were used to determine the relationship between depression (operationally defined as score on the Beck Depression Inventory) and method of presentation of a Piagetian primary illusion, the Müller-Lyer. Furthermore, correlations were determined between tachistoscopic versus free inspection of the Müller-Lyer illusion and forward versus backward digit span (operationally defined as score on the WAIS Digit Span subtest), since forward and backward digit span have been linked theoretically to automatic and effortful processing, respectively.
