Summary Chimpanzee memory has been extensively studied [1,2]. The general assumption is that, as with many other cognitive functions, it is inferior to that of humans [3]; some data, however, suggest that, in some circumstances, chimpanzee memory may indeed be superior to human memory [4]. Here we report that young chimpanzees have an extraordinary working memory capability for numerical recollection — better even than that of human adults tested in the same apparatus following the same… Expand
Do young chimpanzees have extraordinary working memory?
It is reported that, after adequate practice, 2 university students substantially outperformed the chimpanzee on memory for briefly displayed digits in a spatial array; the human subjects received none. Expand
Quantitative Differences Between the Working Memory of Chimpanzees and Humans Give Rise to Qualitative Differences: Subitizing and Cranial Development
Author(s): Read, Dwight W | Abstract: A recent article argues that pure working memory in humans and chimpanzees have the same size. However, the data offered to support this claim show the opposite,Expand
Symbolic representation of number in chimpanzees
It is found that chimpanzees were less proficient at a variety of other cognitive tasks including imitation, cross-modal matching, symmetry of symbols and referents, and one-to-one correspondence. Expand
Chimpanzees flexibly update working memory contents and show susceptibility to distraction in the self-ordered search task
Signals of WM ability in chimpanzees are examined and remarkable similarities between human and chimpanzee WM abilities despite evolutionary and life-history differences are found. Expand
Greater dependence on working memory and restricted familiarity in orangutans compared with rhesus monkeys.
It is found that recognition memory performance in orangutans was controlled by working memory under conditions in which this memory system plays little role in rhesus monkeys, and this finding supports the view that prefrontal expansion in great apes favored working memory. Expand
An analysis of immediate serial recall performance in a macaque
Analysis of a rhesus macaque monkey’s recall performance indicates a number of important parallels with human ISR, consistent with the idea that a single mechanism for short-term serial order memory may be shared across species. Expand
Memory for the order of briefly presented numerals in humans as a function of practice
The present report shows that when two humans are given practice in the Inoue and Matsuzawa (2007) memory task, their accuracy levels match those of Ayumu. Expand
Capuchin and rhesus monkeys but not humans show cognitive flexibility in an optional-switch task
This work suggests that species differences arise from differences in rule encoding and in the relative efficiency of exploiting a familiar strategy versus exploring alternatives, and that working memory influences the advantage of taking a shortcut. Expand
Spontaneous Spatial Mapping of Learned Sequence in Chimpanzees: Evidence for a SNARC-Like Effect
The Chimpanzees' performance was systematically influenced by the spatial arrangement of the stimuli; specifically, they responded quicker when 1 was on the left and 9 on the right compared to the other way around, which suggests that chimpanzees, like humans, spontaneously map a learned sequence onto space.

A comparative study of working memory: Immediate serial spatial recall in baboons (Papio papio) and humans
Two experiments assessed if non-human primates can be meaningfully compared to humans in a non-verbal test of serial recall. A procedure was used that was derived from variations of the Corsi test,Expand


Cognition: Numerical memory span in a chimpanzee
A female chimpanzee called Ai has learned to use Arabic numerals to represent numbers, and it is found that she can remember the correct sequence of any five numbers selected from the range zero to nine. Expand
Use of numbers by a chimpanzee
The present study demonstrates that the chimpanzee was able to describe the three attributes of the sample items and spontaneously organized the ‘word order’. Expand

This work examines eight cognitive cases and finds that similarities between animal and human abilities are small, dissimilarities large, and there is no disparity between brain and mind. Expand
Cognitive Development in Chimpanzees
There are two questions that may be answered through the study of chimpanzee cognitive development: First, ‘what are the common cognitive traits shared by humans and chimpanzees?’ and second, ‘whatExpand
Variation in working memory
Working memory - the ability to keep important information in mind while comprehending, thinking, and acting - varies considerably from person to person and changes dramatically during each person'sExpand
Chimpanzee Spatial Memory Organization
Juvenile chimpanzees, carried around an outdoor field and shown up to 18 randomly placed hidden foods, remembered most of these hiding places and the type of food that was in each. Their searchExpand
