The use and manufacture of tools have been considered to be cognitively demanding and thus a possible driving factor in the evolution of intelligence. In this study, we tested the hypothesis that enhanced physical cognitive abilities evolved in conjunction with the use of tools, by comparing the performance of naturally tool-using and non-tool-using species in a suite of physical and general learning tasks. We predicted that the habitually tool-using species, New Caledonian crows and Galápagos…

Is there a link between the crafting of tools and the evolution of cognition?

TLDR
It is argued that increased sample sizes, novel experimental designs, and a signature-testing approach are required to determine the effect tool crafting has on the evolution of intelligence.

Innovative problem solving in macaws

TLDR
Overall, the successful subjects’ performance was so erratic that it proved difficult to conclude whether they had functional understanding of their multi-stone constructions.

If at first you don't succeed… Studies of ontogeny shed light on the cognitive demands of habitual tool use

TLDR
To better understand the mechanisms underlying routine but non-universal tool use, this work suggests focusing on the ontogeny of tool use and individual variation within populations, to identify the cognitive and developmental mechanisms used when tools are used to solve problems.

Decision-making flexibility in New Caledonian crows, young children and adult humans in a multi-dimensional tool-use task

TLDR
In a similar manner to humans and orangutans, New Caledonian crows and Goffin’s cockatoos can flexibly make profitable decisions in some decision-making tool-use tasks, though the birds may struggle when tasks become more complex.

Do sex differences in construction behavior relate to differences in physical cognitive abilities?

TLDR
The findings suggest that male and female zebra finches either do not differ in their physical cognitive abilities, or any cognitive sex differences in zebra Finches are more specific to tasks more closely associated with nest building.

Old and New Approaches to Animal Cognition: There Is Not “One Cognition”

TLDR
It is argued that the term “cognition” has often been used by applying an anthropocentric viewpoint rather than a biocentric one and that to better understand animal minds, comparative researchers should focus much more on questions and experiments that are ecologically valid.

Reasoning and Generalization in RL: A Tool Use Perspective

TLDR
This paper studies tool use in the context of reinforcement learning and proposes a framework for analyzing generalization inspired by a classic study of tool using behavior, the trap-tube task.

Tool-using puffins prickle the puzzle of cognitive evolution

TLDR
In PNAS, Fayet et al. report on two cases of tool use in a seabird and in two distant populations they recorded Arctic puffins using sticks to scratch themselves, expanding the ever-growing list of tool-using birds through rare observations under natural conditions.

Bending and Unbending of Tools by New Caledonian Crows (Corvus Moneduloides) in a Problem-Solving Context

TLDR
Results show that NCCs can flexibly bend or unbend pliant material to create tools for solving novel tasks and the underlying cognitive mechanisms seemingly varied across individuals although trial-and-error learning prevailed.

Cognitive Processes Associated with Sequential Tool Use in New Caledonian Crows

TLDR
The ability of subjects to use three tools in sequence reveals a competence beyond that observed in any other species, and emphasises the importance of parsimony in comparative cognitive science.

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 development of tool manufacture in humans: what helps young children make innovative tools?

TLDR
The evidence for novel tool manufacture from the comparative literature is reviewed and a growing body of data from children is presented suggesting that innovation of the solution to a problem by making a tool is a much more challenging task than previously thought.

A new approach to comparing problem solving, flexibility and innovation

TLDR
A new approach to comparative research is the Multi-Access-Box, which presents the animal with a novel problem that can be solved in several ways thus offering the possibility to examine species differences in all the above, and extract behavioral and perceptual determinants of their performance.

TLDR
This marks the first demonstration of an empirical relationship between the folding of a neural structure and a cognitive behaviour and provides critical insight into the neural basis of tool use and the role of the cerebellum in cognitive processes.

TLDR
An experiment is presented showing that New Caledonian crows are able to choose tools of the appropriate size for a novel task, without trial-and-error learning.
