- Animals rarely exist in isolation and tend to group with others for a range of reasons
(support, protection & cooperation)
- People are often members of multiple social & family groups
-
- Social neuroscience aims to understand brain mechanisms contributing to

- Oxytocin (OXT) – Social/parental bonding
- § Very important in motivating maternal behaviour and directly impacts feeding by
contracting the milk ducts and causes milk ejection in lactating females.
- § Improves communication between couples discussing a conflict in their
relationship.
- Oxytocin (OXT) – economic trust
- § In humans affiliative behaviour and trust have largely been tested through
economic games.

- Trust - Oxytocin
- The Experiment (in words)
- - 2 groups: Receiving either placebo or nasal spray of oxytocin
- - Play an economic trust game as trustee or investor.
- - Each investor has $12 & can invest 0, 4, 8 or 12 to the trustee (all money invested
is automatically tripled).
- - Trustee then gives back as much money as they choose.
- - Each person plays a single game & are anonymous (though they all spend time in a
waiting room full of other people prior to the game).
- - In one condition people are told they are playing against a real person in another
room… and in a second condition they are told they are playing against a computer

Document Summary
Animals rarely exist in isolation and tend to group with others for a range of reasons (support, protection & cooperation) People are often members of multiple social & family groups. Social neuroscience aims to understand brain mechanisms contributing to development & maintenance of social behaviour. 2 hormones are believed to play a critical role. Very important in motivating maternal behaviour and directly impacts feeding by contracting the milk ducts and causes milk ejection in lactating females. Improves communication between couples discussing a conflict in their relationship. In humans affiliative behaviour and trust have largely been tested through economic games. 2 groups: receiving either placebo or nasal spray of oxytocin. Play an economic trust game as trustee or investor. Each investor has & can invest 0, 4, 8 or 12 to the trustee (all money invested is automatically tripled). Trustee then gives back as much money as they choose.
