Clever Hans, Alex the Parrot, and Kanzi: What can Exceptional Animal Learning Teach us About Human Cognitive Evolution?

  title={Clever Hans, Alex the Parrot, and Kanzi: What can Exceptional Animal Learning Teach us About Human Cognitive Evolution?},
  author={Michael A. Trestman},
  journal={Biological Theory},
The development of cognitive capacities depends on environmental conditions, including various forms of scaffolding. As a result, the evolution of cognition depends on the evolution of activities that provide scaffolding for cognitive development. Non-human animals reared and trained in environments heavily scaffolded with human social interaction can acquire non-species-typical knowledge, skills, and capacities. This can potentially shed light on some of the changes that paved the way for the… Expand
What Frege asked Alex the parrot: inferentialism, number concepts, and animal cognition
ABSTRACT While there has been significant philosophical debate on whether nonlinguistic animals can possess conceptual capabilities, less time has been devoted to considering ‘talking’ animals, suchExpand
One cranium, two brains not yet introduced: Distinct but complementary views of the social brain
This review recounts the history behind the two dominant definitions of a social brain, and proposes ways in which each version of the social brain can benefit from the perspectives, tools, and approaches of the other. Expand
Rethinking music's status as adaptation versus technology: a niche construction perspective
ABSTRACT In this article I critique F. R. S. Lawson's evolutionary theorising about music that appeared in a recent issue of Ethnomusicology Forum. Moreover, I argue that asking whether music is anExpand


The faculty of language: what is it, who has it, and how did it evolve?
We argue that an understanding of the faculty of language requires substantial interdisciplinary cooperation. We suggest how current developments in linguistics can be profitably wedded to work inExpand
Is There Teaching in Nonhuman Animals?
It is argued that adherence to conventional, narrow definitions of teaching, generally derived from observations of human adult-infant interactions, has caused many related but simpler phenomena in other species to go unstudied or unrecorded, and severely limits further exploration of this topic.

The evolution of foresight: What is mental time travel, and is it unique to humans?
It is submitted that mental time travel is not an encapsulated cognitive system, but instead comprises several subsidiary mechanisms that allow prediction of future situations and should be considered in addition to direct evidence of future-directed action. Expand
The gap is social: Human shared intentionality and culture
Human beings share many cognitive skills with their nearest primate relatives, especially those for dealing with the physical world of objects (and categories and quantities of objects) in space andExpand
Cooperative breeding and human cognitive evolution
Despite sharing a recent common ancestor, humans are surprisingly different from other great apes. The most obvious discontinuities are related to our cognitive abilities, including language, but weExpand
Kanzi, evolution, and language
What an irony it is, that the supposed attempt to bring homo sapiens down a few notches in the natural order has taken the form of us humans hectoring another species into emulating our instinctiveExpand
Language, gesture, skill: the co-evolutionary foundations of language
  • K. Sterelny
  • Sociology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2012
The paper shows that an incremental model of language evolution can be developed on the basis of the gestural origins hypothesis, but not if the authors suppose that language originated in an expansion of great ape vocalization. Expand
Grist and mills: on the cultural origins of cultural learning
  • C. Heyes
  • Sociology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2012
It is found that recent empirical work in comparative psychology, developmental psychology and cognitive neuroscience provides surprisingly little evidence of genetic adaptation, and ample evidence of cultural adaptation, raising the possibility that it is not only ‘grist’ but also ‘mills’ that are culturally inherited.

On the lack of evidence that non-human animals possess anything remotely resembling a ‘theory of mind’
After decades of effort by some of our brightest human and non-human minds, there is still little consensus on whether or not non-human animals understand anything about the unobservable mentalExpand
Teaching in Wild Meerkats
Using observational and experimental data, it is shown that wild meerkats teach pups prey-handling skills by providing them with opportunities to interact with live prey, thus accelerating learning without the use of complex cognition. Expand
