[OC] Critical Flicker Fusion Frequency (Hz) across species — a measure of visual temporal resolution

6 comments

1. OC: I created this visualization myself using compiled data from peer-reviewed vision science studies.
   Critical Flicker Fusion Frequency (CFF) measures the temporal resolution of vision — the frequency at which flickering light is perceived as continuous. Higher values indicate faster visual processing.

2. Thank you, this is interesting. Alas not beautiful.

3. It appears mostly related to animal size at this point

4. Matplotlib default colour 👀

   I’d recognise it anywhere.

5. I’d be curious about the hummingbird. Those things seem to live at warp speed

6. I would assume size has a role, since distance = time when it comes to signal processing.

   I’d be curious about other animals. Might be a data project while on pto.
