| Abstract: | In 2 experiments, 12 adult squirrel monkeys and 10 adult titi monkeys were studied in tasks involving reaching for food in near space (arm's reach). Although performance by Ss of the 2 species differed in several ways consistent with previous studies, the species did not differ in the tendency to adopt a habitual position or limb during reaching. The findings contrast with previous work on spatial preferences in these species in tasks involving movement of the whole body. Together with the results of previous studies on movement patterns in these 2 species, the present findings are placed in a comparative psychological framework of the proximate sources of use of space in nature.
