That's why I started with claiming that there is no such consensus. The
usage of these terms does not adhere to strict definitions. It is not
like in law (or math) where definitions come first and usage thereafter,
but it is a post-hoc attempt to try to find definitions that fit the
usage. Perceptual learning would clearly not fit with my criterion
(although I can find some sense in this usage: Processes that are
generally thought as being "purely perceptual" are demonstrated to
depend on prior experience). And  yes: I do think speech perception is a
misnomer. I would think that this research would clearly fit into any
cognitive science unit. But usage is not bound to be consistent.

That was discussed in my example, oomparing 2IFC and S1-S2: Memory may
be involved but not in the focus of perceptual research.
