| Abstract |
Inoue and Matsuzawa (Curr Biol 17: R1004-R1005, 2007) showed that with an accuracy of approximately 79%, the juvenile chimpanzee, Ayumu, could recall the position and order of a random subset of five Arabic numerals between one and nine when those numerals were presented for only 210 ms on a computer touch screen before being masked with white squares. None of nine humans working on the same task approached this level of accuracy. Inoue and Matsuzawa (2007) claimed this performance difference was evidence of a memorial capacity in young chimpanzees that was superior to that seen in adult humans. While the between-species performance difference they report is apparent in their data, so too is a large difference in practice on their task: Ayumu had many sessions of practice on their task before terminal performances were measured; their human subjects had none. 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. |

Attention Score in Context
This research output has an Altmetric Attention Score of 79. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 January 2024.
All research outputs
#553,424
of 25,760,414 outputs
Outputs from Animal Cognition
#138
of 1,586 outputs
Outputs of similar age
#1,652
of 185,093 outputs
Outputs of similar age from Animal Cognition
#2
of 7 outputs
Altmetric has tracked 25,760,414 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 97th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,586 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 35.9. This one has done particularly well, scoring higher than 91% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 185,093 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
