“…Even domain‐general accounts of imitative learning stress that imitative learning must be built upon a species’ capacity to form specific associations between stimuli and responses, which may be scaffolded by motivational biases to attend to social stimuli. It may be possible to demonstrate that SRC effects could be observed in the absence of another individual, which would strongly question the value of the SRC protocol for the study of a special imitative capacity (Ferrucci, Nougaret, Brunamonti, & Genovesio, 2019; Nougaret, Ferrucci, & Genovesio, 2019).…”

What factors affect imitation performance? Varying theories of imitation stress the role of experience, but few studies have explicitly tested its role in imitative learning in non‐human primates. We tested several predictions regarding the role of experience, conspecific presence, and action compatibility using a stimulus–response compatibility protocol. Nineteen baboons separated into two experimental groups learned to respond by targeting on a touch screen the same stimulus as their neighbor (compatible) or the opposite stimulus (incompatible). They first performed the task with a conspecific demonstrator (social phase) and then a computer demonstrator (ghost phase). After reaching a predetermined success threshold, they were then tested in an opposite compatibility condition (i.e., reversal learning conditions). Seven baboons performed at least two reversals during the social phase, and we found no significant difference between the compatible and incompatible conditions, although we noticed slightly faster response times (RTs) in the compatible condition that disappeared after the first reversal. During the ghost phase, monkeys showed difficulties in learning the incompatible condition, and the compatible condition RTs tended to be slower than during the social phase. Together, these results suggest that (a) there is no strong movement compatibility effect in our task and that (b) the presence of a demonstrator plays a role in eliciting correct responses but is not essential as has been previously shown in human studies.

“…In experiment 2, we demonstrated that both monkeys were able to monitor the choices of the ghost agent, maintaining a stable performance not only in the trials following their own choices, but also in those following trials completed by the computer. Some previous studies have investigated social interactions using computers as nonsocial agents 45,56 . Here, in addition to confirming that macaque monkeys are able to extract information from a ghost agent, we assessed their ability to maintain their involvement in task execution and to interact www.nature.com/scientificreports/ dynamically with the ghost agent in their housing environment.…”

“…In the second experiment, based on recent studies revealing the ability of macaque monkeys to learn in the so-called "ghost display" condition 44,45 , we tested the monkeys' ability to perform a second version of the same task that required interacting in turns with a "ghost agent". The trials performed by the monkey were interspersed with trials performed by the ghost agent; therefore, in all the trials performed by the monkey after the ghost agent, the correct choice depended on the choice made by the ghost agent.…”

In neurophysiology, nonhuman primates represent an important model for studying the brain. Typically, monkeys are moved from their home cage to an experimental room daily, where they sit in a primate chair and interact with electronic devices. Refining this procedure would make the researchers’ work easier and improve the animals’ welfare. To address this issue, we used home-cage training to train two macaque monkeys in a non-match-to-goal task, where each trial required a switch from the choice made in the previous trial to obtain a reward. The monkeys were tested in two versions of the task, one in which they acted as the agent in every trial and one in which some trials were completed by a “ghost agent”. We evaluated their involvement in terms of their performance and their interaction with the apparatus. Both monkeys were able to maintain a constant involvement in the task with good, stable performance within sessions in both versions of the task. Our study confirms the feasibility of home-cage training and demonstrates that even with challenging tasks, monkeys can complete a large number of trials at a high performance level, which is a prerequisite for electrophysiological studies of monkey behavior.

“…Can monkeys use postures and behavior in an attempt to communicate with humans, either to attract their attention or conversely to stop them from engaging in some activity? An emerging literature exists on human-monkey interactions within a cognitive framework (see Nougaret et al, 2019, for a review). Monkeys not only attend to human behavior, they can also quickly solve problems by watching how humans solve them (Falcone et al, 2012).…”

Self‐Injurious behavior in rhesus macaques: Issues and challenges

Some monkeys housed in research facilities develop abnormal behavior ranging from stereotypic to the more serious condition of self-injurious behavior (SIB).We initially sought to understand how and why monkeys engaged in SIB and more importantly why only a small percentage of laboratory monkeys, with seemingly similar housing and background, developed this disorder. Of particular importance was the recognition that different pathways might lead to SIB and that strong individual differences would affect the manifestation of this disorder and the response to treatment. We developed a comprehensive plan to identify effective treatment and prevention strategies. We started with characterizing the disorder in terms of prevalence and types of environments in which it was found. We then conducted observations on a cohort of SIB and control monkeys to identify conditions associated with SIB (e.g., disordered sleep) as well as clinical disease states and congenital defects that could be precipitating factors.We examined the environmental events that triggered episodes of SIB in monkeys with the disorder and evaluated three models that might explain the reinforcement contingencies associated with SIB, including tension reduction, self-stimulation, and social communication. Possible treatments for SIB such as environmental enrichment, social housing, and pharmacotherapy were tested by our group and others. To date, no single treatment has been found to abolish SIB, and each of these treatments is impacted by individual differences. To develop possible prevention strategies, we examined colony management and health records to find risk factors for SIB. These risk factors generalized to other facilities, and considerable effort was expended by all behavioral managers at these facilities to reduce early life stress exposure, to minimize the length of individual cage housing by emphasizing pair housing, and to reduce the possible stressfulness of various veterinary/medical procedures by implementing positive reinforcement training.
