Flexibility in Choosing Decision Policies in Gathering Discrete Evidence Over Time

The datasets are related to the article “Flexibility in Choosing Decision Policies in Gathering Discrete Evidence Over Time.” This study involved two different experiments: a visual experiment and an auditory experiment. So, there are separate datasets for them.
In both tasks, subjects completed four blocks of 168 double and single-pulse trials. In almost 80% of all trials, the stimuli were presented to the subject in two discrete pulses, with the pulses being separated by a temporal gap or an inter-pulse interval (IPI). The duration of each IPI was chosen from a set of four values (0, 120, 360, 480, 1080 ms). Three stimulus strength levels were employed for each pulse of the double-pulse trials, 25%, 30% and 35% for the visual task and 200%, 150% and 100% noise-to-signal ratios for the auditory task.

本数据集与论文《在随时间收集离散证据时选择决策策略的灵活性》密切相关。该研究包含两项不同的实验：一项视觉实验和一项听觉实验。因此，针对这两项实验分别设有独立的数据集。在两项任务中，受试者需完成包含168次双脉冲和单脉冲的四个实验区块。在几乎所有80%的试验中，刺激以两个离散脉冲的形式呈现给受试者，脉冲之间通过时间间隔或脉冲间间隔（IPI）分隔。每个IPI的持续时间从一组四个值（0、120、360、480、1080毫秒）中选择。对于双脉冲试验的每个脉冲，采用了三种刺激强度水平，视觉任务中为25%、30%和35%，听觉任务中为200%、150%和100%的信噪比。
