Abstract Using Matsuzawa’s hierarchical system of classification, I compared tool-use patterns of tufted capuchins (Cebusapella) to those of chimpanzees (Pantroglodytes). The results indicated that wild C. apella exhibit fewer and less complex tool-use patterns than do captive C. apella and wild and captive P. troglodytes. Although most patterns of tool-use observed among P. troglodytes occur in captive C. apella, there are some notable exceptions, including tool-use in communicative contexts… 
The evolution of combinatoriality and compositionality in hominid tool use: a comparative perspective
TLDR
A novel system to evaluate the level of hierarchical nesting of tool components in single tool use activities is devised, demonstrating that nonhuman primates, and by extension, the last common ancestor shared by Pan and Homo, are capable of basic combinatoriality; however, their technology does not approach the compositionality observable in modern human tool use.
Discrimination of functionally appropriate and inappropriate throwing tools by captive tufted capuchins (Cebus apella)
TLDR
The results suggest that capuchin monkeys, like chimpanzees studied in similar experiments, are sensitive to a variety of functionally relevant tool features.
Tools for thought or thoughts for tools?
  • A. Kacelnik
  • Biology
    Proceedings of the National Academy of Sciences
  • 2009
TLDR
It is reported that rooks, corvids that do not habitually use tools in the wild, appear to possess tool-related capabilities hitherto known only in their tool-using relatives, the New Caledonian crows (Corvus moneduloides).
How does stone-tool use emerge? Introduction of stones and nuts to naïve chimpanzees in captivity
TLDR
The cognitive capability required for nut-cracking behavior and the process through which the nut-Cracking behavior emerges are clarified and the patterns of object manipulation exhibited by the subjects are analyzed.
Self-control and tool use in tufted capuchin monkeys (Cebus apella).
TLDR
The results indicate that capuchins are capable of delaying gratification when a higher quality reinforcer is present and that tool experience can influence levels of self-control in this task.
Energetic Payoff of Tool Use for Capuchin Monkeys in the Caatinga: Variation by Season and Habitat Type
TLDR
Predictions from the energetic bottleneck and opportunity models are analyzed to explain the use of stones to crack open encased fruit by capuchins in dry environments and indicate that specific nutritional requirements may play a role in explaining the continuous consumption of encased Fruit.
A Capuchin monkey (Cebus apella) recognizes when people do and do not know the location of food
TLDR
The aim of the present study was to specify whether the subjects learned a simple conditional discrimination or a causal relationship that seeing leads to knowing, and to suggest that one capuchin monkey learned to recognize the relationship between seeing and knowing.
Insightful problem solving and creative tool modification by captive nontool-using rooks
TLDR
It is shown that rooks, a species that does not use tools in the wild appears to possess an understanding of tools rivaling habitual tool users such as New Caledonian crows and chimpanzees, suggesting that the ability to represent tools may be a domain-general cognitive capacity rather than an adaptive specialization.
The possibility that tool use is a purely phenotypic trait can be safely excluded.
TLDR
The hand-reared rooks studied by Bird and Emery can shape hooks out of wire, use two tools in a sequenceto achieve a goal, drop stones inside atube to dislodge a platform holding areward, and select the properties of thestones they drop according to the need sof the task, and so on.

Performance in a tool-using task by common chimpanzees (Pan troglodytes), bonobos (Pan paniscus), an orangutan (Pongo pygmaeus), and capuchin monkeys (Cebus apella).
TLDR
The results indicate that all these species can solve these tasks, however, only the performance of apes is consistent with emerging comprehension of the causal relations required for the avoidance of errors in the more complex tasks.
The Production and Use of Digging Tools by Monkeys: A Nonhuman Primate Model of a Hominid Subsistence Activity
TLDR
It is hypothesized that Homo habilis could have produced digging tools analogous to those produced by monkeys in this investigation and that the use of such implements would have provided evolutionary advantages in harsh prehistoric environments.
Token-mediated tool-use by a tufted capuchin monkey (Cebus apella)
TLDR
The subject learned to use chips to request tools following the same general pattern seen in great apes performing analogous tasks, that is, initial discrimination followed by an understanding of the relationship among tokens, tools, and their functions.
The manufacture and use of tools by capuchin monkeys (Cebus apella).
TLDR
The manufacture and use of tools in captive groups of tufted capuchin monkeys (Cebus apella) are described, providing further evidence that capuchins possess extensive manipulative propensities and emphasize the significance of the normal social environment in the full expression of these propensity.
Tool use by chimpanzees (Pan troglodytes) of the Arnhem Zoo community
TLDR
Chimpanzees are the only consistent and habitual tool users and tool makers for nonhuman primates, and the use of tool composites or "meta-tools" has been reported.

TLDR
Early anecdotal information and systematic studies of tool use in capuchin monkeys (Cebus spp.) are summarized, indicating that capuchins never develop an understanding of the requirements of the tool tasks presented.
Tool use in wild capuchin monkeys (Cebus albifrons trinitatis)
TLDR
White‐fronted capuchins were observed to use leaves as cups to retrieve water from tree cavities, and engage in habitual tool use, as defined by McGrew's classificatory scheme of tool using behavior.
Language, tools and brain: The ontogeny and phylogeny of hierarchically organized sequential behavior.
TLDR
Chimpanzees have an identical constraint on hierarchical complexity in both tool use and symbol combination, which matches that of the two-year-old child who has not yet developed the neural circuits for complex grammar and complex manual combination of objects.
