In two experiments, squirrel monkeys were exposed to centrifugally generated, artificial gravity and trained to respond for food reinforcement at selected gravity (g) levels. Experiment I involved a single g value; in Exp. II, subjects were trained to discriminate among two or three g values. After training, generalization tests were administered over a 1.1‐g to 2.1‐g range. The major findings were as follows: (a) single‐stimulus training yielded a linear relationship between percentage of responding and magnitude of gravity. (b) Two‐valued discrimination training produced gradient peaks which were shifted from S D in a direction away from S Δ . This effect was cancelled when S D was located equidistant between two S Δ stimuli, (c) Gradient form was independent of the S D ‐S Δ difference, but related to continuum location and/or intensity of discriminative stimuli.
