"Apes as intuitive statisticians"
Abstract
Numerous animal species are capable of selecting the larger of two quantities even when
those are presented concurrently and fall outside either object file or subitizing range.
Much less is known about animals’ ability to spontaneously estimate probabilities, an
ability that should be distinguished from sensitivity to reinforcement probabilities. In
this talk I will present data on how great apes estimate probabilities in tasks that
require comparing two probabilities and extrapolating from populations to samples to net
the highest possible payoff. These data have implications for several disciplines
including comparative cognition, logic, and experimental economics.
