动机和执行功能都是完成目标导向行为所必需的。调查这些过程相互作用方式的研究开始出现，并暗示额中回（MFG）是相关神经机制相互作用的位点。然而，这项研究主要集中在状态动机，并没有检查功能偏侧化。本研究探讨了接近和回避动机的特质水平对与执行功能相关的神经过程的影响。功能磁共振成像进行，而参与者进行了颜色词Stroop任务。分析确定了特质接近和回避动机（通过问卷测量）调节与执行控制相关的激活的大脑区域。接近被假设为与左侧MFG激活，而回避被假设为与右侧MFG激活。结果支持这两个假设。目前的研究结果表明，额中回区域在自上而下的控制，以指导行为，根据动机目标。
Motivation and executive function are both necessary for the completion of goal-directed behavior. Research investigating the manner in which these processes interact is beginning to emerge and has implicated middle frontal gyrus (MFG) as a site of interaction for relevant neural mechanisms. However, this research has focused on state motivation, and it has not examined functional lateralization. The present study examined the impact of trait levels of approach and avoidance motivation on neural processes associated with executive function. Functional magnetic resonance imaging was conducted while participants performed a color-word Stroop task. Analyses identified brain regions in which trait approach and avoidance motivation (measured by questionnaires) moderated activation associated with executive control. Approach was hypothesized to be associated with left-lateralized MFG activation, whereas avoidance was hypothesized to be associated with right-lateralized MFG activation. Results supported both hypotheses. Present findings implicate areas of middle frontal gyrus in top-down control to guide behavior in accordance with motivational goals.
