摘要
更长的凝视时间能决定高风险的投资决策吗?最近的研究已经测试了凝视如何影响人们的决定和凝视效应的边界。目前的实验使用了自适应注视条件操作，通过增加一个自决定选项来测试更长凝视时间是否可以决定风险投资决策。结果表明，每个选项的期望值和注视时间都会影响人们的决策。这一结果与Krajbich et al.(2010)提出的注意扩散模型(attention diffusion model, aDDM)一致，该模型认为凝视可以通过放大选择的价值来影响选择过程。因此，当人们没有明确的偏好时，凝视时间会影响决策。结果还表明，选项之间的相似性和计算难度也会影响注视效果。这一结果与先前使用期权相似度来表示难度的研究结果不一致，表明期权相似度和计算难度都诱发了不同的决策困难的潜在机制。
Can longer gaze duration determine risky investment decisions? An interactive perspective.
Can longer gaze duration determine risky investment decisions? Recent studies have tested how gaze influences people's decisions and the boundary of the gaze effect. The current experiment used adaptive gaze-contingent manipulation by adding a self-determined option to test whether longer gaze duration can determine risky investment decisions. The results showed that both the expected value of each option and the gaze duration influenced people's decisions. This result was consistent with the attentional diffusion model (aDDM) proposed by Krajbich et al. (2010), which suggests that gaze can influence the choice process by amplify the value of the choice. Therefore, the gaze duration would influence the decision when people do not have clear preference.The result also showed that the similarity between options and the computational difficulty would also influence the gaze effect. This result was inconsistent with prior research that used option similarities to represent difficulty, suggesting that both similarity between options and computational difficulty induce different underlying mechanisms of decision difficulty.
