Is this interesting for you? Stay tuned for more! We applied this protocol to other scenarios, and found very interesting behaviour 👀

Briefly, we measured contrast thresholds for performing an array of tasks on simple visual stimuli across exposure durations ranging from 150 microseconds (!) to 100 ms. Bloch's law accounted well for forced-choice detection and discrimination, as well as subjective visibility judgements!

Unfortunately it's another of these laws, Bloch's law. If you are interested, we will soon post a preprint confiming its validity with simple stimuli and an array of perceptual tasks. We are also testing it on complex realistic stimuli and results should also be ready soon
