What's a hormone? |
It is a regulatory substance produced in an organism, and transported in tissue fluids, such as blood, to stimulate specific cells or tissues into action. They act like chemical messengers. |
|
What is homeostasis ? |
Homeostasis is the process of keeping constant conditions throughout the body. |
|
Give two examples for the effect of hormones on human behaviour and studies that show them. |
1- Cortisol and its effects on memory in Newcomer et al.'s experiment. 2- Oxytocin and trust in Baumgartner et al.'s experiment. |
|
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. |
