Primary Outcome Measures
NameTimeMethod
<p>1. The change in choice behaviour in the Dictator Game before and after the<br /><br>Cyberball Game between chronically rejected and stable accepted children.<br /><br>Choice behaviour will be measured by the donated percentage of coins (out of 10<br /><br>coins) per trial between themselves and the recipient (that is, a best friend,<br /><br>an anonymous (neutral) recipient, or a sex matched excluder from the Cyberball<br /><br>Game). Participants can choose from three fixed divisions, namely: 7 for<br /><br>themselves, and 3 for the recipient (7/3); 5 for themselves, 5 for the<br /><br>recipient (5/5); or 3 for themselves, 7 for the recipient (3/7).<br /><br>2. The difference in blood oxygen dependent (BOLD) signal changes (an indirect<br /><br>measure of neural activation) during choice behaviour in the Dictator Game<br /><br>before and after the Cyberball Game between chronically rejected and stable<br /><br>accepted children.</p><br>
Secondary Outcome Measures
NameTimeMethod
<p>1. Seed based functional connectivity during resting state<br /><br>2. The brain*s default mode network (DMN)<br /><br>3. anatomical (frontostriatal) connectivity</p><br>
