Our guests, in order of appearance, are Adam Pazda (University of Rochester), Coren Apicella (University of Pennsylvania) and Sally Farley (University of Baltimore).
The topics discussed by our guests have been covered previously on the Research Digest blog, including: the psychological effects of the colour red, the effects of voice pitch (the specific study covered by Dr Apicella is here), and the effects of mimicry (see also).
This episode was released to coincide with Valentine's Day 2015. For more Valentine's-themed psychology, check out these posts from the Research Digest archive, and there's also much more from The Psychologist magazine.
