Exp 1: fMRI-study about reasoning with cardinal directions

web_srfrmi_final

In this experiment we presented participants with the arrangement of three stimuli. One third of the problems were determinate (i.e., allowing only for one arrangement), one third indeterminate (allowing for more than one possible arrangement), and one third with negated spatial information (implying as well an indeterminate arrangement). The results show an increase in reasoning difficulty (i.e., error rates from determinate over indeterminate to negated relations). The brain activations show additional actication for negated stimuli.

Classification: fMRI-study; Arrangement of three objetcs; Visual presentation
