Abstract

The supremacy of misleading perception as a function of an empirical orientation was investigated in an experiment where perceptual and logical cues competed in problems of inference of measurement. The 20 subjects, 5-7 years old, comprised 10 empirically and 10 deductively oriented children who were given 36 such problems after showing that they could successfully solve similar problems, in the absence of perceptual alternatives. According to prediction, the "empirical" group made more errors than the "deductive" group, and proportionately more of their errors were on problems where perception directly contradicted logic. The data were seen to clarify further the relationship between perception and logic at the onset of operational (logical) thinking and were interpreted to suggest that the residue of previous modes of thinking (perceptually bound) are still used in certain situations even after logical thinking is manifest, perception still misleading even in the presence of logical thinking.
