cog001Throughout the next section, we will examine your preferences over a health condition. The health condition we will examine is cognition as measured by the time to complete the Trail Making Task.

The Trail Making Task is a test where participants must connect the dots between alternating numbers and letters in ascending order. An example of a completed Trail Making Test is below.


Typically, participants take 50-60 seconds to complete the test. Completion speed can be a good proxy for cognition. For references as to what different speeds represent in terms of cognition, please see the following scale.


Please answer the next question assuming the following about your health:

A few years ago, your health seriously deteriorated due to an unknown cause. Doctors could not find the cause and could not do anything to improve your health. Today, due to your health condition, your cognition is such that you would need 230 seconds to complete the Trail Making Task. Prior to your health deteriorating, assume you were able to complete the task in 45 seconds.

How would you view a 230 second completion time due to your illness?
