Abstract
This study aims to collect data both on strategic decision-making and on individual’s ability of assessing other’s intentions, beliefs and emotions, known as Theory of Mind (ToM). We use a sets of ring game (Kneeland, 2015) as well as our altered version ring game with focal strategies, as a measure of strategic sophistication. Particularly, we are interested to see if subject's level of strategic sophistication is sensitive to the focal strategy we created, and whether subjects are able to perform best responses when strategic uncertainty is reduced. We use an eye-gaze test (Baron-Cohen et al., 2001) as a measure of ToM ability. We conduct a laboratory experiment with 200 subjects.

Experimental Design

Experimental Design
In a laboratory setting at University of California - San Diego, we run a two stage experiment. In the first stage, we ask the subjects to complete 36 eye gaze tasks. For stage two, we randomize the subjects into groups of four. The subjects play a sets of 20 ring games, and stay within the same group.
Experimental Design Details
Randomization Method
Subjects take a randomized seat number when they enter the lab.
Randomization Unit
We randomize at the individual level.
