眼动操纵技术在决策研究中的应用前景：改变决策行为

眼动追踪技术因干扰性低、客观性强、获取数据丰富而准确等优点, 被广泛应用于行为决策研究。通过操纵眼动过程, 可使决策结果按照预期的方向改变, 建立决策过程和结果的因果链, 为决策的干预研究提供思路。基于外源性眼动操纵、注视追随操纵这两类研究, 介绍了行为决策领域眼动操纵的基本方法及原理、常见操纵指标、操纵效果, 并分析和讨论了不同操纵类别的优缺点。在实验设计中考虑决策者策略及偏好的差异, 结合计算建模等方法进一步丰富操纵指标和分析方法, 并将该方法的优势拓展到其它领域是眼动操纵研究未来的重要方向。

The prospect of gaze manipulation technology in decision-making research: Altering decision-making

The eye-tracking technique has been widely used in behavioural decision-making research owing to its advantages: 1) does not interfere with the decision-making process, 2) objectively collects information and 3) provides accurate and rich process data. To reveal the causality between eye movement and decision making, gaze manipulation could be utilised to examine whether shifting visual attention can alter choice behaviour. Gaze manipulation is classified into two types: exogenous manipulation and gaze-contingent manipulation. The two types of gaze manipulation have the same goals but have different characteristics, thus typically limiting their use for different research areas.
