Competitive Fighting between Mice with Different Hereditary Backgrounds

It was hypothesized that Piaget's argument on behalf of the reorganization of cognitive processes would gain empirical support from a color/form, matching similar objects problem for 52 (29 boys, 23 girls) 6-year-olds from a variety of socioeconomic backgrounds. The instrument had 32 frames, each of which had three red or blue objects, some of regular and some of irregular shape. After color or form dominance for each child was established, frames were presented in which the dominant dimension could be chosen only through cognitive reorganization. Indications of cognitive reorganization for form-processing children included switching to color choices when all three objects were of identical shape, taking significantly (p < .05) greater time to make a choice for irregularly shaped objects, and having judges find indications of the use of parts of irregularly shaped objects for matches in verbal explanations by each child.
