Two tasks used in Lauriola et al. (2007) are available for use, a computer based version is also in development:
Description:
Purpose
|
|
The Ambiguity-Probability Tradeoff Task was designed to assess individuals' attitude toward ambiguity, which is defined as uncertainty about uncertainty. The task is modeled after Ellsberg-type two-color problems.

Questions
|
|
41 trials with a forced choice between 2 options, one ambiguous urn and one unambiguous urn. Both urns contain 160 balls of 2 different colors.
- In the ambiguous urn, the proportion of balls of each color is *not* specified.
- In the unambiguous urn, the proportion of balls of each color is specified.
