Ok, which kind of Christmas shopping brain are you? When undecided about whether to buy (is it worth it, does she want it, could I get it cheaper, i.e. decision-making under ambiguity), are you more likely to answer your impulse to buy (opt for risk) or muddle through the pros and cons / various contextual possibilities (opt for ambiguity)?
An fMRI or a look under the tree may give you the answer...
