TLDR
The results suggest partial convergence and partial divergence between development of logicomathematical cognition in chimpanzees and humans.Abstract:
Two experiments investigated the spontaneous construction of precursory logicomathematical operations by human-enculturated and language-reared chimpanzees (Pan troglodytes, Pan paniscus) when they were interacting freely with objects. In experiment 1, three chimpanzees ranging in age from 6 to 18 years were presented with sets of six objects. Chimpanzees constructed equivalence, order and reversibility relations within single sets of objects as well as between two or three contemporaneous sets of objects. The chimpanzees’ logicomathematical operations were more advanced, including infrequent and minimal operations on three sets, than those of some previously investigated younger nonenculturated common chimpanzees. In experiment 2, six chimpanzees ranging in age from 6 to 21 years were presented with sets of 12 objects. Chimpanzees constructed more advanced operations on single sets, but not on contemporaneous sets. The results suggest partial convergence and partial divergence between development of logicomathematical cognition in chimpanzees and humans.read more

Working Memory: A Cognitive Limit to Non-Human Primate Recursive Thinking Prior to Hominid Evolution
TL;DR: This article explored the possibility that recursion is not part of the cognitive repertoire of non-human primates such as chimpanzees due to limited working memory capacity and found evidence for expansion of working memory during hominid evolution reflected in changes in the products of conceptually framed activities such as stone tool production.

Problem solving skills in young yellow-crowned parakeets (Cyanoramphus auriceps).
TL;DR: T tasks designed to assess human infant development were investigated with a series of tasks presented to young parakeets to assess their means-end problem solving abilities, indicating that these abilities may not emerge in any particular order for these birds as they supposedly do for human infants.

Simultaneous development of vocal and physical object combinations by a Grey parrot (Psittacus erithacus): bottle caps, lids, and labels.
TL;DR: The authors found a comparable, if limited, parallel combinatorial development in a Grey parrot (Psittacus erithacus), and suggest that the search for and arguments concerning responsible substrates and common behavior should be approached with care and should not be restricted to the primate line.

Concurrent disjoint and reciprocal classification by Cebus apella in seriation tasks: evidence for hierarchical organization
TL;DR: Capuchin monkeys (Cebus apella) achieved high levels of principled linear size seriation with sequence lengths not normally achieved by children below the age of six years, suggesting an adaptive advantage for hierarchical over linear organization.

The value of the Piagetian framework for comparative cognitive studies.
TL;DR: It is argued for the need for descriptive systems such as the Piagetian framework to complement programs that look for cellular and molecular bases or mathematical models to explain behavior.

The Growth of Logical Thinking from Childhood to Adolescence
TL;DR: In this paper, the authors describe how people download the growth of logical thinking from childhood to adolescence, but end up in malicious downloads, rather than enjoying a good book with a cup of coffee in the afternoon, instead they cope with some harmful virus inside their laptop.

The codes of man and beasts.
TL;DR: Exposing the chimpanzee to language training appears to enhance the animal's ability to perform some kinds of tasks but not others; the abilities that are enhanced involve abstract judgment, as in analogical reasoning, matching proportions of physically unlike exemplars, and completing incomplete incomplete representations of action.
