Describe Baumgartner's and Newcomer's experiments. |
-Newcomer: He experimented on levels of cortisol and human declarative memory. He experimented on three groups: Group 1: high dose of cortisol (160 mg tablets) for 4 days Group 2: low dose cortisol (40 mg tablets) Group 3: no cortisol (placebo tablets) -Baumgartner: examines the role of oxytocin in trust in economic behaviour. Participants played a trust game which is used by economists by neuroscientists, and then they were subjected to an fMRI. |
