title: Backward and forward masking in Macaca mulatta.
abstract: 8 highly trained rhesus monkeys were examined on both backward and forward masking to determine the feasility of studying masking in unrestrained monkeys and of studying perceptual phenomenon without the confounding of linguistic variables. It was found that monkeys could respond well under the given conditions. The data indicated a more pronounced effect of the masking stimulus on backward masking than on forward masking.
