Chimpanzee minds: suspiciously human?
Chimpanzees versus humans: it's not that simple
We don't need a microscope to explore the chimpanzee's mind
TLDR
It is called for recognition of this problem, and a shift from experimental paradigms that cannot resolve this question, to ones that might allow researchers to intelligently determine when it is necessary to postulate the presence of a system which reasons about both behavior and mental states.
From Nonhuman to Human Mind
TLDR
Some of the latest research on chimpanzee and canine psychology that allows inferences to be made regarding the human mind challenge evolutionary theory are reviewed.
Chimpanzee Theory of Mind: Looking in All the Wrong Places?
I respond to an argument presented by Daniel Povinelli and Jennifer Vonk that the current generation of experiments on chimpanzee theory of mind cannot decide whether chimpanzees have the ability to
Do chimpanzees know what others can and cannot do? Reasoning about ‘capability’
TLDR
Seven chimpanzees’ ability to predict which of two human experimenters could deliver a tray containing a food reward was tested, indicating that chimpanzees do not spontaneously (or after considerable training) use limb visibility as a cue to predict the ability of a human to perform particular physical tasks.
What Apes Know about Seeing
TLDR
What constitutes evidence for level 1 visual perspective taking (hereafter, VPT1) in nonhuman primates is examined and it is argued that the critics’ position is misguided.
Moral ape philosophy
TLDR
A set of intermediate conditions between a sometimes helpful chimpanzee and moral man are formulated to arrive at a notion of objective morality as conceived from a first person point of view in terms of propositional attitudes and reasons.
Moral ape philosophy
TLDR
A philosophical look at morality using the chimpanzees as a prism is taken and a notion of objective morality as conceived from a first person point of view in terms of propositional attitudes and reasons is arrived at.

TLDR
The findings provide little evidence that young chimpanzees understand seeing as a mental event and demonstrate that, even though young chimpanzee subjects spontaneously attend to and follow the visual gaze of others, they simultaneously appear oblivious to the attentional significance of that gaze.
CHAPTER 15 – Do Apes Ape?
Do apes and children know what they have seen?
Abstract. Chimpanzees and young children understand much about what other individuals have and have not seen. This study investigates what they understand about their own visual perception.
Reasoning about beliefs: a human specialization?
TLDR
There is some reason to suspect that theory of mind is unique to the authors' species, and that its original function was to provide a more abstract level of describing ancient behavioral patterns (such as deception, reconciliation, and gaze following) that humans share in common with many other species.
The Domestication of Social Cognition in Dogs
TLDR
It is found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old, even those that have had little human contact, do show these skills.
The Cultural Origins of Human Cognition
This work builds a bridge between evolutionary theory and cultural psychology. The author is one of very few people to have done systematic research on the cognitive capacities of both nonhuman
How do apes ape?
TLDR
Together, these studies suggest that apes ape by employing a portfolio of alternative social-learning processes in flexibly adaptive ways, in conjunction with nonsocial learning.
Do chimpanzees know what conspecifics know?
TLDR
Chimpanzees know what conspecifics have and have not seen (do and do not know), and that they use this information to devise effective social-cognitive strategies.
