====Stroop and Simon task====
The performance of Stroop and [[Simon task]]s were monitored on 10 healthy young adults using [[magnetic resonance image]] (MRI)  scanning.<ref name = Peterson>{{cite journal | last1 = Peterson | first1 = B.S. | last2 = Kane | first2 = M.J. | last3 = Alexander | first3 = G.M. | last4 = Lacadie | first4 = C. | last5 = Skudlarski | first5 = P. | last6 = Leung | first6 = H.C. | last7 = Mat | first7 = J. | last8 = Gore | first8 = J.C. | year = 2002 | title = An event-related functional MRI study comparing interference effects in the Simon and Stroop tasks | journal = Cognitive Brain Research | volume = 13 | issue = 3| pages = 427–440 | doi=10.1016/s0926-6410(02)00054-x| pmid = 11919006 }}</ref> Functional images were acquired at specific time intervals during each subject's scan.<ref name="Peterson"/> Brain activation during the Stroop and Simon task was remarkably similar including [[anterior cingulate]], [[supplementary motor cortex]], [[visual association cortex]], [[inferior temporal cortex]], inferior [[parietal cortex]], inferior [[frontal cortex]], dorsolateral [[prefrontal cortex]], and [[caudate nuclei]].<ref name="Peterson"/> Interference effects in the Stroop and Simon tasks activate similar brain regions at similar time distributions.<ref name="Peterson"/>
