I’m not even completely kidding about this one. I imagine sleep is a fairly powerful association–if you’re able to get it going in the first place. (In narcolepsy it’s somehow miswired to emotion circuits: severe narcoleptics can fall asleep in the middle of any kind of hilarity…but are those really emotion circuits? Bring me your tired, your insomniacs, your narcoleptics…this troubled brain yearns to be published).
So I found out from Mary Roach’s “Bonk” that B.F. Skinner ditched his professorship to be with a hot student (maybe T.A.)–from the University of Chicago. Da-amn.
P.S. the second & third panels are negative and positive conditioning, respectively.
