Experimental Details

Interventions

Intervention(s)
We run a lab experiment on decision making under risk to study how correlation sensitivity changes due to repeated decision making with feedback.

Primary Outcomes

Primary Outcomes (end points)
The key variables are a measures of correlation sensitivity, and subjects' choices during repeated decision making. We describe all variables in detail in the document "designPAP.pdf".

Experimental Design

Experimental Design
The experiment consists of three blocks. In blocks I and III, we measure subjects' correlation sensitivity. These blocks are identical across treatments. Block II differs across three between-subject treatments. In treatment 1, subjects make 25 repeated decisions with outcome feedback for a single choice task. In treatment 2, subjects see a sequence of 25 random outcomes for a single choice task, without making any choices. In treatment 3, subjects make 25 decisions without outcome feedback.

Treatment 1 is the main treatment. Treatments 2 and 3 can be seen as control conditions.

We describe the experimental design in detail in the document "designPAP.pdf".
