Over the last decade, there has been a robust debate in decision neuroscience and psychology about what mechanism governs the time course of decision-making. Historically, the most prominent hypothesis is that neural architectures accumulate information over time until some threshold is met, the so-called Evidence Accumulation hypothesis. However, most applications of this theory rely on simplifying assumptions, belying a number of potential complexities. Is changing stimulus information perceived and processed in an independent manner or is there a relative component? Does urgency play a role? What about evidence leakage? Although the latter questions have been the subject of recent investigations, most studies to date have been piecemeal in nature, addressing one aspect of the decision process or another. Here we develop a modeling framework, an extension of the Urgency Gating Model, in conjunction with a changing information experimental paradigm to simultaneously probe these aspects of the decision process. Using state-of-the-art Bayesian methods to perform parameter-based inference, we find that (a) information processing is relative with early information influencing the perception of late information, (b) time varying urgency and evidence accumulation are of roughly equal strength in the decision process, and (c) leakage is present with a time scale of ∼200-250 ms. We also show that these effects can only be identified in a changing information paradigm. To our knowledge, this is the first comprehensive study to utilize a changing information paradigm to jointly and quantitatively estimate the temporal dynamics of human decision-making.

决策中信息处理的紧迫性、泄漏和相对性质。

在过去的十年中,决策神经科学和心理学界一直在激烈争论什么机制控制着决策的时间进程。从历史上看,最突出的假设是神经架构会随着时间的推移积累信息,直到达到某个阈值,即所谓的证据积累假设。然而,该理论的大多数应用依赖于简化假设,掩盖了许多潜在的复杂性。不断变化的刺激信息是以独立的方式感知和处理的还是存在相关成分?紧迫感起作用了吗?证据泄露怎么办?尽管后一个问题是最近调查的主题,但迄今为止的大多数研究本质上都是零碎的,只针对决策过程的一个方面或另一个方面。在这里,我们开发了一个建模框架,紧急门控模型的扩展,结合不断变化的信息实验范式,同时探索决策过程的这些方面。使用最先进的贝叶斯方法进行基于参数的推理,我们发现(a)信息处理与影响后期信息感知的早期信息相关,(b)时变紧迫性和证据积累大致相等决策过程中的强度,以及 (c) 泄漏的时间范围约为 200-250 毫秒。我们还表明,这些影响只能在不断变化的信息范式中识别。据我们所知,这是第一次利用不断变化的信息范式来联合和定量估计人类决策的时间动态的综合研究。(PsycInfo 数据库记录 (c) 2020 APA,
