Fusional vergence ranges of the monkey: A behavioral study

Original Articles


Fusional vergence ranges were behaviorally determined for two rhesus monkeys and two human subjects using random dot stereograms as stimuli. The subject performed a two-alternative forced choice form discrimination of discretely presented stimuli and the fusional vergence stimulus was changed during the intertrial intervals. The fusional vergence measurements for the monkey were similar to those for the human subjects.
