An intuition of ambivalence in cognition is particularly strong for complex decisions, for which the merits and demerits of different options are roughly equal but hard to compare. We examined information search in an experimental paradigm which tasked participants with an ambivalent question, while monitoring attentional dynamics concerning the information relevant to each option in different Areas of Interest (AOIs). We developed two dynamical models for describing eye tracking curves, for each response separately. The models incorporated a drift mechanism towards the various options, as in standard drift diffusion theory. In addition, they included a mechanism for intrinsic oscillation, which competed with the drift process and undermined eventual stabilization of the dynamics. The two models varied in the range of drift processes postulated. Higher support was observed for the simpler model, which only included drifts from an uncertainty state to either of two certainty states. In addition, model parameters could be weakly related to the eventual decision, complementing our knowledge of the way eye tracking structure relates to decision (notably the gaze cascade effect).
在认知中，对于复杂决策，人们往往会有一种模棱两可的直觉，因为不同选项的优缺点大致相当，但难以比较。我们在一个实验范式中研究了信息搜索，该范式要求参与者回答一个模棱两可的问题，同时监测与每个选项相关的注意力动态，涉及不同的兴趣区域 (AOIs)。我们为每个单独的反应开发了两个描述眼动追踪曲线的动态模型。这些模型包含了一种向各个选项漂移的机制，就像标准的漂移扩散理论一样。此外，它们还包括一种内在振荡机制，与漂移过程竞争，并破坏了动力学的最终稳定。这两个模型在假设的漂移过程范围上有所不同。对于只包含从不确定状态到两个确定状态之一的漂移的更简单模型，观察到了更高的支持率。此外，模型参数与最终决策的关系较弱，这补充了我们对眼动追踪结构与决策关系的了解（特别是注视级联效应）。
