Primary Outcome Measures

Name	Time	Method
<p>The main study parameters is the test scores of the CANTAB cognition tests.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>The secondary parameters are the choices in the lotteries determining risk and<br /><br>time preferences, the answers from questionnaires about risk and time<br /><br>preferences, the changes in metabolic energy expenditure, as well as the<br /><br>following physiological parameters: heart rate variability, CO2 blood<br /><br>concentration, O2 saturation level, physical activity level, blood pressure,<br /><br>skin temperature, and breathing rate. Subjects will also receive a heuristics<br /><br>battery survey at the end of the test day, which measures the sensitivity to<br /><br>bias behavior. This includes measuring if automatic processes are tended to<br /><br>make more often than deliberative decisions in order to solve a problem.</p><br>
