情景记忆指导价值决策:认知机制、计算建模与神经通路
Episodic memory-guided value-based decision-making: Mechanisms, computational frameworks, and neural pathways
摘要
情景记忆在指导价值决策中具有重要作用。本研究围绕情景记忆指导价值决策的几个核心问题展开论述:(1)在记忆加工机制方面,考察灵活重组、选择性提取、衰退与遗忘以及建构性错误对价值决策的影响;(2)在计算建模框架方面,比较经典强化学习模型与最新的情景强化学习模型在建模决策过程中的关注点及差异;(3)在神经通路解析方面,内侧颞叶–前额叶通路是核心神经网络,尤其以内侧颞叶(海马体及周围结构)与前额叶之间的功能交互为主,海马体–纹状体交互可能构成情景记忆与经验价值更新发生联系的重要接口,而基底外侧杏仁核–眶额叶通路则作为结果特异性奖赏记忆系统的补充机制。未来研究应重点关注基于记忆指导价值决策中的动力学机制与神经模式,以及错误记忆影响价值决策的认知与神经机制及其与真实记忆之间的差异。
Abstract
Memory-guided value-based decision-making refers to situations in which individuals retrieve option-related episodic memories when choosing among multiple options. Such retrieval shapes value estimation and, in turn, guides the decision process. Current research highlights a central role of episodic memory in value-based decision-making and addresses three core questions: (1) how distinct properties of episodic memory influence decision-making: flexible recombination, selective retrieval, memory decay and active forgetting, and the constructive nature of episodic memory; (2) how different computational modeling frameworks account for episodic influences on value-based decision-making: model-free reinforcement learning (MF-RL), which emphasizes incremental learning of cached values and is often associated with habitual control; model-based reinforcement learning (MB-RL), which evaluates actions by simulating an internal model of environmental structure; and episodic reinforcement learning (ERL), which emphasizes retrieval and sampling of specific past episodes or trajectories; and (3) how neural pathways support episodic memory-guided value-based decision-making: this process primarily relies on interactions between the medial temporal lobe (MTL), including the hippocampus and surrounding structures, and the orbitofrontal cortex (OFC) and ventromedial prefrontal cortex (vmPFC), with the striatum and basolateral amygdala contributing in complementary ways. Future research should focus on the dynamics and neural signatures of memory-based valuation, as well as on the cognitive and neural mechanisms by which false memories bias value-based decision-making and how these mechanisms differ from those associated with true memories.关键词
