The Wason Selection Task

Question 3

You've got bored of working for a card games manufacturer, and you're now working as a security executive in a bar (you're a bouncer). It's your job to ensure that the rule governing the consumption of alcohol is strictly enforced. It states:

If a person drinks an alcoholic drink, then they must be over the age of 21 years old.

The cards below reprsent the drink of choice and age of four customers at your bar. (Each card represents one person: one side shows what they're drinking - note the card on the left shows beer,  the alcoholic kind! - the other side their age.) Please indicate which card or cards you definitely need to turn over, and only that or those cards, in order to determine whether the rule is broken in the case of each of the four customers. (To indicate that it is necessary to turn over a card, simply "select" the card by clicking in the little box beneath it.)

Question 3 of 3

Really Deep Thought

The 'dirty secret of contemporary neuroscience': we have no idea what the correct level of analysis is, because there is no universally accepted theory of how the brain codes information.
