Repetitive Transcranial Magnetic Stimulation of Dorsolateral Prefrontal Cortex Affects Performance of the Wisconsin Card Sorting Task during Provision of Feedback
Figure 3
Behavioral tasks. (a) WCST: the four
cards shown on the top in the computer screen are reference cards, and the card
on the bottom is the test card. The subjects could move a yellow bar which was
displayed under the reference cards by pressing the left button of a mouse with
their index finger. Pressing the right button with the middle finger confirmed
the selection of the card followed by negative or positive feedback. The
subjects had to find out the rule of classification (color, shape, and number)
by trial and error. (b) Control task: the
test card was identical to one of the reference cards. The rest was the same as
WCST.
