There are a wide variety of methods to do that: EEG, MEG, fMRI, PET ...

The time required to learn Braille may vary depending on factors such as age, partial/full and early/late blindness and individual differences (see here), but what has come out of studies such as this is that visual deprivation appears to speed up Braille learning. In the study I cite, all subjects received the same degree of training, but individuals who ...

It is going to mean bad things. If you can only create stimuli with a predefined non uniformly sampled set of "levels" then the the corresponding percent correct that the staircase will track will depend on the threshold of an individual observer. For example, if you can create stimuli with levels of 0, 1, 2, 3, ..., 100, 110, 130, 170, 250, 410, where for ...
