Consumer buying motivations can be distinguished into three categories: functional, experiential, or symbolic motivations (Keller, 1993). Although prior neuroimaging studies have examined the neural substrates which enable these motivations, direct comparisons between these three types of consumer motivations have yet to be made. In the current study, we used 7 Tesla (7T) functional magnetic resonance imaging (fMRI) to assess the neural correlates of each motivation by instructing participants to view common consumer goods while emphasizing either functional, experiential, or symbolic values of these products. The results demonstrated mostly consistent activations between symbolic and experiential motivations. Although, these motivations differed in that symbolic motivation was associated with medial frontal gyrus (MFG) activation, whereas experiential motivation was associated with posterior cingulate cortex (PCC) activation. Functional motivation was associated with dorsolateral prefrontal cortex (DLPFC) activation, as compared to other motivations. These findings provide a neural basis for how symbolic and experiential motivations may be similar, yet different in subtle ways. Furthermore, the dissociation of functional motivation within the DLPFC supports the notion that this motivation relies on executive function processes relatively more than hedonic motivation. These findings provide a better understanding of the underlying neural functioning which may contribute to poor self-control choices.
功能型、体验型或象征型动机(凯勒,1993年)。尽管先前的神经影像学研究已经考察了促成这些动机的神经基础,但这三种类型的消费者动机之间的直接比较尚未进行。在当前的研究中,我们使用7特斯拉(7T)功能磁共振成像(fMRI),通过指示参与者在强调这些产品的功能、体验或象征价值的同时观看常见消费品,来评估每种动机的神经关联。结果表明,象征型和体验型动机之间的激活大多一致。不过,这些动机的不同之处在于,象征型动机与内侧前额叶皮层(MFG)激活有关,而体验型动机与后扣带回皮层(PCC)激活有关。与其他动机相比,功能型动机与背外侧前额叶皮层(DLPFC)激活有关。这些发现为象征型和体验型动机如何可能相似但又在细微方面存在差异提供了神经基础。此外,DLPFC内功能型动机的分离支持了这样一种观点,即这种动机相对享乐型动机而言更多地依赖执行功能过程。这些发现有助于更好地理解可能导致自我控制选择不佳的潜在神经功能。
