Abstract
When given an array of pieces of food, adult chimpanzees selected the largest piece first, even when the ratio of sizes was only 1.11 to 1.00. When food stimuli were differently oriented, the animals showed a tendency to overestimate the horizontal as compared to the longitudinal or the vertical dimension. "The usefulness of food-size preference as a basis for further examination of primate visual capacity was noted." From Psyc Abstracts 36:05:5EF88M.
