One human-reared monkey without any training frequently gazed at her human respondent; as with apes, extensive exposure to humans may promote some human-like responses monkeys. Another withheld when beneficial, whereas 3rd learned obtain food deceptively competitive Such one withholding information another suggest that primates' an experimental situation is explainable terms response inhibition conditional discrimination learning.
