“…use tool sets, such as a stone to crack a nut and then a stick to pry out pieces of nut kernel (Westergaard & Suomi, 1993). They also spontaneously use a short rigid stick to obtain a longer rigid stick (Anderson & Henneman, 1994), or a rigid stick to obtain an out-of-reach flexible one that could be used to dip into a baited 90° angled tube (Sabbatini et al, 2014).…”

The abilities to perform skilled hand movements and to manipulate objects dexterously are landmarks in the evolution of primates. The study of how primates use their hands to grasp and manipulate objects in accordance with their needs sheds light on how these species are physically and mentally equipped to deal with the problems they encounter in their daily life. We report data on capuchin monkeys, highly manipulative platyrrhine species that usually spend a great deal of time in active manipulation to search for food and to prepare it for ingestion. Our aim is to provide an overview of current knowledge on the ability of capuchins to grasp and manipulate objects, with a special focus on how these species express their cognitive potential through manual behaviour. Data on the ability of capuchins to move their hands and on the neural correlates sustaining their actions are reported, as are findings on the manipulative ability of capuchins to anticipate future actions and to relate objects to other objects and substrates. The manual behaviour of capuchins is considered in different domains, such as motor planning, extractive foraging and tool use, in both captive and natural settings. Anatomofunctional and behavioural similarities to and differences from other haplorrhine species regarding manual dexterity are also discussed.

“…From Köhler’s early work on insight in chimpanzees [ 25 ] through to contemporary animal problem-solving studies investigating water displacement [ 26 , 27 , 28 ], sequential problem-solving [ 7 , 8 , 19 , 23 , 29 , 30 ], hook-making [ 23 , 31 ], connectivity [ 19 , 32 ], gravity [ 32 , 33 , 34 , 35 ], and planning [ 18 , 22 , 36 , 37 ], one key question has been the extent to which animals use mental trial and error. Dennett [ 38 ] famously referred to animals with this ability as Popperian creatures because their “hypotheses die in their stead.” That is, by being able to mentally represent different states of the world and the potential outcome of actions directed toward changing these states, an animal can try out different courses of action in their heads and then avoid ones that might kill them, or reduce their chances of reproduction, in the real world.…”

New Caledonian Crows Use Mental Representations to Solve Metatool Problems

Summary One of the mysteries of animal problem-solving is the extent to which animals mentally represent problems in their minds. Humans can imagine both the solution to a problem and the stages along the way [ 1 , 2 , 3 ], such as when we plan one or two moves ahead in chess. The extent to which other animals can do the same is far less clear [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Here, we presented New Caledonian crows with a series of metatool problems where each stage was out of sight of the others and the crows had to avoid either a distractor apparatus containing a non-functional tool or a non-functional apparatus containing a functional tool. Crows were able to mentally represent the sub-goals and goals of metatool problems: crows kept in mind the location and identities of out-of-sight tools and apparatuses while planning and performing a sequence of tool behaviors. This provides the first conclusive evidence that birds can plan several moves ahead while using tools.

“…Moreover, finding an unexpected cognitive ability may alert field researchers to consider why such an ability may have evolved and where it could be utilized in the animals' natural world. Although it is typically difficult for one individual to do both field and laboratory work (although see; Fragaszy et al, 2013;Hayashi, Mizuno, & Matsuzawa, 2005;Inoue-Nakamura & Matsuzawa, 1997;Sabbatini et al, 2014), researchers can collaborate or, at the very least, read each other's' literatures and incorporate each other's ideas.…”

The Importance of a Truly Comparative Methodology for Comparative Psychology

Comparative research has taught us much about the evolution and development of human and animal behavior. Humans share not just physical and biological similarities with other species, but also many behavioral traits and, in some of these cases, the psychological mechanisms behind them. Comparing behavior and cognition across multiple species can help scientists to pinpoint why and when in phylogenetic history a behavior may have evolved, how it evolved, and what the mechanisms behind it are (Tinbergen, 1963). While the comparative approach has proven quite effective in addressing these questions, comparing behavior across multiple species is not as easy and straightforward as it may initially seem. Rigorous methodology and careful interpretation of results is crucial to answering any of these questions definitively. The focus of the current article is on the comparative methodology and the important factors that need to be addressed in order for comparative research to be effective. We first discuss the benefits and importance of comparative research, followed by the challenges that need to be overcome in good comparative work. We then discuss experimental economics as one “model system” for comparative work that has proven particularly good at addressing such issues, and comment on other approaches. We conclude with future directions for comparative research with an eye on important methodological and theoretical considerations.
