The limited hold is scientific terminology—laboratory slang, really—for a good way to use the marker and reinforcer to speed up response to a cue. We're all used to sluggish responses. You call folks for supper, and in due course, they come; meanwhile the soufflé falls or the soup gets cold.

A good thing? A bad thing? A nonexistent thing?

I was excited! What a good way to interest students in operant conditioning!
