[DIGITAL EFFECTS] NANCY KANWISHER: So to remind you, we've been talking last week about doing two things at once-- asking all sort of questions of what we might want to know about face perception in the brain-- there are some questions.
But at the same time, the agenda has been to consider the different methods available in human cognitive neuroscience and what kinds of questions each one can answer.
So last week, we talked about a bunch of them, and today, we're going to wrap this up talking about TMS and animal studies.
But first, I just want to remind you very briefly-- I won't go through in excruciating detail-- we talked about behavioral methods, which are great for characterizing internal representations, as you saw with face inversion effects and some of the other behavioral data, they have major disadvantages, which is that with behavior, you're just measuring the output.
It's pretty sparse.
And from that, you have to infer all the stuff that happened in between the retina-- or whatever your sensory modality is-- and the output.
All that internal mental stuff you have to infer just from the output.
So it's amazing that that works at all, and you have to be really smart to do it.
And lots of people have been doing that for a long time, but it's challenging.
So why not look inside?
