Substitution Heuristic on Proportional Tasks
Sponsor: Michelle Hurst, PhD
Summary
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.

Interventions
Additional Incentive
During this behavioral intervention, participants will be given additional compensation for correct answers.
Response Delay
During this behavioral intervention, participants will not be allowed to respond with their judgements until after a certain amount of time has passed.
Baseline Performance
In this intervention, the participant completes the task as it is typically administer for a baseline performance measure. The participant can respond at will and does not receive incentive for correct responses.
