FIGURE 5.12 Brain Activity during Hypnosis (a) Researchers found that the anterior cingulate cortex (shown in the cross-hairs), a part of the brain involved in conflict monitoring, is activated in all people when viewing incongruent trials during the Stroop task (for instance, when the word “Red” appears in blue font). (b) However, under hypnosis, when instructed to ignore the content of the words and just name the font color, highly suggestible people do not show increased activation in this brain region during incongruent trials (Raz, Fan, & Posner, 2005).
