This fMRI study investigated mental simulation of state/psychological and action verbs during adolescence. Sixteen healthy subjects silently read verbs describing a motor scene or not (STIMULUS: motor, state/psychological verbs) and they were explicitly asked to imagine the situation or they performed letter detection preventing them from using simulation (TASK: imagery vs. letter detection). A significant task by stimuli interaction showed that imagery of state/psychological verbs, as compared to action stimuli (controlled by the letter detection) selectively increased activation in the right supramarginal gyrus/rolandic operculum and in the right insula, and decreased activation in the right intraparietal sulcus. We compared these data to those from a group of older participants (Tomasino et al. 2014a). Activation in the left supramarginal gyrus decreased for the latter group (as compared to the present group) for imagery of state/psychological verbs. By contrast, activation in the right superior frontal gyrus decreased for the former group (as compared to the older group) for imagery of state/psychological verbs.
这项功能磁共振成像（fMRI）研究调查了青少年时期对状态/心理动词和动作动词的心理模拟。16名健康受试者默读描述运动场景或非运动场景的动词（刺激：运动、状态/心理动词），并被明确要求想象相应情境，或者他们执行字母检测任务以防止他们进行模拟（任务：想象与字母检测）。一项显著的任务与刺激的交互作用表明，与动作刺激（由字母检测控制）相比，状态/心理动词的想象选择性地增加了右侧缘上回/颞叶岛盖和右侧脑岛的激活，并减少了右侧顶内沟的激活。我们将这些数据与一组年长参与者的数据进行了比较（托马西诺等人，2014年a）。对于后一组（与当前组相比），在状态/心理动词的想象过程中，左侧缘上回的激活减少。相比之下，对于前一组（与年长组相比），在状态/心理动词的想象过程中，右侧额上回的激活减少。
