Mental functions
from Larry Sanger's text...Mental functions and cognitive processes can be used interchangeably to mean such functions or processes as perception, introspection, memory, imagination, conception, belief, reasoning, volition, and emotion--in other words, all the different things that we can do with our minds. A specific instance of engaging in a cognitive process is a mental event. The event of perceiving City Hall is, of course, different from the entire process, or faculty, of perception--one's ability to perceive things. In other words, in instance of perceiving is different from the ability that makes it possible.
