“…Chimpanzees, as well as many other animals, typically have little difficulty with this type of task whether information regarding alternative choices is acquired individually [Nissen et al, 1938;Schusterman, 1962], or through the observation of a conspecific partner [Martin et al, 2011]. Reversal learning and transfer of training paradigms have been used extensively to test if and how individuals respond when the payoff associated with objects or stimuli can change over time.…”

As a result of environmental variability, animals may be confronted with uncertainty surrounding the presence of, or accessibility to, food resources at a given location or time. While individuals can rely on personal experience to manage this variability, the behavior of members of an individual's social group can also provide information regarding the availability or location of a food resource. The purpose of the present study was to measure how captive chimpanzees individually and collectively adjust their foraging strategies at an artificial termite mound, as the availability of resources provided by the mound varied over a number of weeks. As predicted, fishing activity at the mound was related to resource availability. However, chimpanzees continued to fish at unbaited locations on the days and weeks after a location had last contained food. Consistent with previous studies, our findings show that chimpanzees do not completely abandon previously learned habits despite learning individually and/or socially that the habit is no longer effective.

“…2). The innovative idea that distinguishes it from prior examples of multisubject touch-panel setups (Martin, Biro, & Matsuzawa, 2011;Subiaul, Cantlon, Holloway, & Terrace, 2004) is the use of a single, "shared" screen instead of dual screens. A 22-in.…”

We report on the development of a novel shared touch-panel apparatus for examining a diverse range of topics in great ape social cognition and interaction. Our apparatus-named the Arena System-is composed of a single multitouch monitor that spans across two separate testing booths, so that individuals situated in each booth have tactile access to half of the monitor and visual access to the whole monitor. Additional components of the system include a smart-film barrier able to restrict visual access between the booths, as well as two automated feeding devices that dispense food rewards to the subjects. The touch-panel, smart-film, and feeders are controlled by a PC that is also responsible for running the experimental tasks. We present data from a pilot behavioral game theory study with two chimpanzees in order to illustrate the efficacy of our method, and we suggest applications for a range of topics including animal social learning, coordination, and behavioral economics. The system enables fully automated experimental procedures, which means that no human participation is needed to run the tasks. The novel use of a touch-panel in a social setting allows for a finer degree of data resolution than do the traditional experimental apparatuses used in prior studies on great ape social interaction.

“…Such gaze-following behavior was shown to enhance when accompanied by a facial expression (Teufel et al, 2010). The effect of social cues on choice behavior has been studied in chimpanzees (Horner et al, 2011; Martin et al, 2011). Face recognition and responses to facial expression develop within the first 2 months in infant chimpanzees, but learning of gestural cues such as pointing may take much longer in this species (Tomonaga et al, 2004).…”

Primates live in complex social groups and rely on social cues to direct their attention. For example, primates react faster to an unpredictable stimulus after seeing a conspecific looking in the direction of that stimulus. In the current study we tested the specificity of facial cues (gaze direction) for orienting attention and their interaction with other cues that are known to guide attention. In particular, we tested whether macaque monkeys only respond to gaze cues from conspecifics or if the effect generalizes across species. We found an attentional advantage of conspecific faces over human and cartoon faces. Because gaze cues are often conveyed by gesture, we also explored the effect of image motion (a simulated glance) on the orienting of attention in monkeys. We found that the simulated glance did not significantly enhance the speed of orienting for monkey-face stimuli, but had a significant effect for images of human faces. Finally, because gaze cues presumably guide attention toward relevant or rewarding stimuli, we explored whether orienting of attention was modulated by reward predictiveness. When the cue predicted reward location, face, and non-face cues were effective in speeding responses toward the cued location. This effect was strongest for conspecific faces. In sum, our results suggest that while conspecific gaze cues activate an intrinsic process that reflexively directs spatial attention, its effect is relatively small in comparison to other features including motion and reward predictiveness. It is possible that gaze cues are more important for decision-making and voluntary orienting than for reflexive orienting.
