内外动机对青少年记忆的影响及其神经机制

The influence of extrinsic and intrinsic motivation on memory in adolescents and the underlying neural mechanisms

动机是一切行为的核心,动机可分为外在和内在动机。青少年时期既是记忆的关键期,也是动机发展的特殊时期。然而,目前关于内外动机影响青少年记忆的研究才刚刚起步,尚不清楚外在和内在动机影响青少年记忆的规律和机制是否一致,也不清楚二者如何交互影响记忆。本研究将结合认知范式和脑成像技术,考察外在和内在动机如何分别影响以及交互影响青少年记忆。这将有助于更加全面、深刻理解内外动机影响青少年记忆的独特规律和机制,为科学提升青少年动机和记忆效果提供研究证据。

Motivation is crucial to behavior. Motivation can be classified as extrinsic and intrinsic motivation. Adolescence is a critical period of memory and a special period of motivation development.However, the investigation of how extrinsic and intrinsic motivation impact memory is on the start stage. It remains unclear whether the rules and mechanisms of extrinsic and intrinsic motivation’ impact on memory are common or specific and how the extrinsic and intrinsic motivation interacts with each other to impact memory. This proposed project will combine the cognitive paradigm and functional magnetic resonance imaging technology to investigate how extrinsic and intrinsic motivation separately influences and interacts with each other to influence adolescents’ memory. These evidences will comprehensively and significantly advance our understanding of the unique laws and mechanisms of how extrinsic and intrinsic motivation affect memory in adolescents, and provide scientific evidence for how to improve the motivation and memory in adolescents.
