简要总结
The goal of this clinical trial is to test whether or not adults use a substitution heuristic when reasoning about proportions. The main question it aims to answer is:
Do adults use a substitution heuristic when judging non-symbolic proportions, leading them to answer an easier, yet incorrect question?
Researchers will compare performance at baseline with one of two conditions in order to see if forced behavioral changes can change performance on the task.
Participants will be asked to compare two images and judge which has the higher proportion of the target color. Each participant will also be assigned to one of two condition where they either receive a further incentive for correct selections or are required to use more time when making their calculations.

结局指标
主要结局
Proportion Correct
时间窗: up to 20 minutes
Accuracy will be measured for each trial and combined into an overall score (i.e., proportion of trials correct).
Reaction Time
时间窗: up to 20 minutes
Reaction time will also be tracked (i.e., time it takes to respond), with a faster reaction time indicating ease and/or efficiency with the task.
