Ep 163: Psych Files Brief #4: Animals Smiling, Yogurt De-Stressing, and the Psychology of Success

Do animals smile?  Do they feel emotions and if so how many kinds of feelings do they share with us? In this episode we also take a look at the probiotics in yogurt - how do they affect your thinking and do they might help protect you from stress.  It turns out that these probiotics increase the production of the neurotransmitter GABA which helps quiet down your neurons.  I also talk about the work of female psychologists: Carol Dweck on the psychology of success, and and a tribute to Evelyn Hooker whose research helped in removing homosexuality from the DSM in 1973.
