Humans 1, Chimps 0: Correcting the Record

Jason Collins critiques the claim of superior chimpanzee working memory, citing methodological flaws in studies. He argues that with training, humans can match chimp performance, emphasizing accurate scientific representation.

Humans 1, Chimps 0: Correcting the Record

In a blog post, Jason Collins revisits a claim made in 2012 regarding the working memory of chimpanzees, specifically referencing a chimp named Ayumu, who demonstrated impressive memory skills in a numerical task. Initially, this performance was interpreted as evidence of superior working memory in chimps compared to humans. However, Collins highlights that this conclusion is flawed due to methodological issues. Research by Cook and Wilson in 2010 pointed out that Ayumu had extensive practice on the task, while the human participants did not. Subsequent studies indicated that with moderate training, humans could match or even exceed Ayumu's performance. A literature review by Read et al. in 2022 suggested that chimpanzee working memory is comparable to that of 4 to 5-year-old humans, but falls short of adult human capabilities, particularly in tasks involving two-digit numbers. Collins argues that the initial assertion of chimpanzees having superior working memory is not supported by evidence and distracts from more meaningful research on memory in both chimpanzees and humans. He emphasizes the importance of accurate representation in scientific discourse to further understanding of primate evolution and cognition.

Human intelligence's evolution is linked to enhanced information processing capacity, not specific biases. Genetic enhancements in processing abilities across memory, attention, and learning systems differentiate human cognition, impacting functions like rule representation and abstract thinking. This perspective redefines human intelligence evolution.

AI: What people are saying
The discussion surrounding Jason Collins' critique of chimpanzee working memory studies reveals several key points of contention.
  • Many commenters argue that humans have an advantage due to extensive prior exposure and training compared to chimps.
  • There is skepticism about the validity of the studies, with calls for more unbiased comparisons and consideration of different contexts.
  • Some participants express a sense of relief or humor regarding human cognitive abilities in relation to chimps.
  • Concerns are raised about the ethical implications of using primates in research and the need for better scientific practices.
  • Several comments highlight the importance of transparency and accessibility in scientific research.

On favour of humans, people have usually seen the numbers thousands to millions of times in their lifetimes, while chimps would have seen them few dozens of times at best. So "training the same time" for humans and chimps is def misleading, would love to see this with an abstract or uncommon characters like Japanese (for a Western audience).

Despite the correction, I still expect to see (perhaps only slight or niche) skills with their corresponding mental attributes which great apes and extinct hominids possess(ed) which outweigh our own

An example which springs to mind is the utterly absurd physical traits and likely corresponding hand-eye coordination Homo naledi possessed in order to perform their burial rituals

It took world-class climbers risking their lives to even reach the burial chamber, let alone do it repeatedly without modern climbing gear or even light

Despite their size and build being advantageous, I do not see how their mental attributes wouldn’t be more conducive to related skills than even trained (but tool-less) Homo sapiens

"with even very moderate practice, humans can match Ayumu’s performance."

The article is misnamed, the actual score is 1 to 1.

To make any unbiased claim, we'd need results from chimps who've captured live humans. Short of that, I'm fairly certain it was always Humans 1, Chimps 0.

This isn't surprising to anyone who has seen videos of "flash anzan". The numbers flash up on the screen and you have to add them up:

The chimp got extensive training because he did not attend school.

The humans had more than 20 years of training, going through mandatory education and then college.

It is not a competition between species. It's a competition between quality training on the one hand and on the other, the notion that some species are somehow born with skills.

I wonder if chimps understand where they are headed after the tests. i.e. the nice room were they play games for treats, or the other room where they get injected with various concoctions for unfathomable reasons.

I think humans tend to naively apply our own constructs to describe what we think defines intelligence, but this habit does not necessarily generalize onto other species. As an aside, for similar reasons I'd wager generalized AI will be a surprise event rather than an incremental discovery.

Recent studies described Goldfish that can remember certain types of problems beyond a year later. Far beyond what anyone assumed possible for such a simple creature.

Some people are unique, as I met one lady that could remember 93 non-sequential digits. While she was not successful academically, it would be unwise to play card games with that person for money. =)

Primates belong in their own habitats, and should be left alone unless people have a well defined _necessary_reason_ to exploit them as subjects.

Have a great day, =3

Can't express how relieved I am that I am tentatively not inferior to a chimpanzee.

Back in the day, there were lots of websites where you could play the game.

You can improve your performance at this game by playing in extremely high contrast, so you can use the retinal afterimage to give you more time to study the numbers. Similar to how that "LSD" video requires you reconstruct persistence of visionsl while watching a too-slow animation of light painting.

Such a weird case, since any human could directly objectively test the claim on their own.

Thank You. It is easy to miss these follow up studies.

The period of "closed science", which really took on steam after the extensions of copyright in 1976 and 1998, will be look backed upon as rampant with dishonesty and corruption.

If you are in academia and you are not publishing your stuff to the public domain, including your git repo, please take some time to think about this and do what you need to do to pivot.
