Chimps have us beat when it comes to short-term visual memory (Humans can't even come close).
Mantis shrimp have us beat when it comes to quickly detecting colors since they have twelve photoreceptors vs. our three.
Insects have us beat when it comes to anything in the UV spectrum (we're completely blind to it). Many insects also cannot move their eyes but are still have to use vision for collision detection and navigation.
Birds have us beat when it comes to visual acuity. Most of them also do not move their eyeballs in spacial directions like we do but still have excellent visual navigation skills.
- monadgonad 6y agoI think the point was that brains are the best pattern and object detection computers, not necessarily just human brains.
- nwallin 6y agoHumans have visual processing which converts the signals from our three types of cones into tens to hundreds of millions of shades of color. Mantis shrimp don't have this processing. Mantis shrimp can only see 12 shades. Human color detection is about six orders of magnitude greater than mantis shrimp's.
- aeternum 6y agoRight, but the theory is that they have us beat when it comes to speed since they are directly sensing the colors whereas we are doing a bunch of post-processing.
