"Sarris has introduced some much-needed structure into the field of relational psychophysics. Particularly compelling is the use of the comparative, developmental, and evolutionary perspectives to enrich our ideas about context effects in human psychophysics. But Sarris doesn't stop there. He integrates ideas from philosophy, systems theory, physics, biology, and others, all in the context of laboratory work which illustrates fundamental ideas of how most living creatures perceive sensory stimuli in relation to each other and to their environmental setting." - Lawrence Ward, Department of Psychology and The Brain Research Centre, University of British Columbia
