Аннотация: Delay of gratification in 3 chimpanzees (Pan troglodytes) was examined by using a paradigm based on research with children. The chimpanzees either pressed a door-bell button during a trial and received one reward (the immediate reward) or did not press the doorbell and received another reward (the delayed reward). Two chimpanzees were language-trained, and a 3rd was non-language-trained. Foods (one more-preferred and one less-preferred), photographs of those foods, or lexigrams representing those foods were presented to the chimpanzees. All 3 chimpanzees delayed gratification when foods were physically present. One language-trained chimpanzee also delayed gratification with lexigrams present, and the 2nd language-trained chimpanzee delayed gratification in all three conditions. Language competence and early rearing are proposed as explanations for the different performances of these chimpanzees. © 1999 John Wiley & Sons, Inc. Dev Psychobiol 34: 119–127, 1999
