“…There is some evidence that nonhuman primates can extract information from conspecifics. They may orient themselves from the locations, movements, calls and gazes of others (Menzel 1974;Coussi-Korbel 1994;Tomasello et al 1998;Call et al 2000;Hirata & Matsuzawa 2001;Vick et al 2001). Specific vocalizations act as food calls, which contain information on the location, quantity and quality of the food (e.g.…”

We investigated the ability of monkeys to use referential information about environmental resources from cues passively transmitted by conspecifics. The subjects and their companions were four young males belonging to a group of semifree-ranging Tonkean macaques (Macaca tonkeana) raised in a 2-acre wooded park. In a first experiment, a subject had to orient its search strategy from the information obtained from a conspecific. It first had to smell the mouth of a companion having just eaten a food item, and then search for same quality food in the field. The results showed that subjects adjusted their foraging speed according to the value of the reward to be found. They were able to recognize the food resource on the basis of the item previously eaten by their companion. In a second experiment, we asked whether the subjects could anticipate a given food quantity from smelling a companion associated with that given food quantity. When testing whether subjects oriented their search strategy on the basis of companion's identity, they did not appear to use it as a referential cue to food quantity. They nonetheless adapted their foraging speed according to food value. Both experiments indicated that macaques are liable to assess and select food from information extracted from conspecifics, and hence avoid some costs associated with individual food searching.

“…That is, they learn head or eye direction as a cue to respond to the appropriate side without any appreciation that these are indicators of another's visual orientation per se ; as head direction is a more obvious cue, this association may be more readily learned. Alternatively, the advantage for head over eye direction cues may reflect an underlying tendency to attend to this form of cue; for many of species of nonhuman primates, head orientation may be a reliable signal of another individual's visual orientation (see Kobayashi & Koshima, 1997;2001).…”

“…All the baboons except Green had previously been tested on a categorisation task (Bovet & Vauclair, 1998). Balthazar and Ida had been tested on the object-choice task 12 months before the present study commenced (neither had performed at above-chance levels; Vick, Bovet & Anderson, 2001). They received their daily food ration (fruit, dried pellets and vegetables) at the end of daily training and testing.…”

The ability of four olive baboons (Papio anubis) to use human gaze cues during a competitive task was investigated; the baboons were allowed to remove only the non-fixated one of two simultaneously presented food items. Three baboons successfully learned to exploit the human's head orientation as a cue to obtain a food item, and one individual also learned to use eye direction alone. As the baboons did not receive prior training with gross gestural cues, their performance suggests that the competitive paradigm may be more conducive to gaze monitoring in nonhuman primates than the standard objectchoice paradigm. However, the baboons were insensitive to whether the experimenter could actually perceive the food item and therefore use of visual orientation cues may not be indicative of visual perspective-taking abilities in baboons. Performance was disrupted by the introduction of a screen and objects to conceal the food items, and to a lesser degree by the absence of movement in cues presented.

“…Vick et al (2001) tested four subjects for their use of a gaze or a glance cue. None of the subjects reached criterion with either cue, not even after receiving around 750 trials.…”

Referential gestures are of pivotal importance to the human species. We effortlessly make use of each others' referential gestures to attend to the same things, and our ability to use these gestures show themselves from very early in life. Almost 20 years ago, James Anderson and colleagues presented an experimental paradigm with which to examine the use of referential gestures in non-human primates: the object-choice task. Since then, numerous object-choice studies have been made, not only with primates but also with a range of other animal taxa. Surprisingly, several non-primate species appear to perform better in the object-choice task than primates do. Different hypotheses have been offered to explain the results. Some of these have employed generalizations about primates or subsets of primate taxa that do not take into account the unparalleled diversity that exists between species within the primate order on parameters relevant to the requirements of the object-choice task, such as social structure, feeding ecology, and general morphology. To examine whether these broad primate generalizations offer a fruitful organizing framework within which to interpret the results, a review was made of all published primate results on the use of gazing and glancing cues with species ordered along the primate phylogenetic tree. It was concluded that differences between species may be larger than differences between ancestry taxa, and it is suggested that we need to start rethinking why we are testing animals on experimental paradigms that do not take into account what are the challenges of their natural habitat.
