Note I am not necessarily suggesting there is a right or wrong method to use. There can be good reasons to use adjustment tasks depending on the context of what you're doing. But our field must be more careful in interpreting perceptual estimates in different studies estimated by different methods.

And when you're referring visual processes back to the brain, it matters where in retinotopic space they are presented, for what duration, what contrast etc. This should really be obvious but apparently it isn't (and again, this is not about any one study). /GrumpyOldFartMode
