Experimental Design
Participants perform in two timed tests of 4 minutes, where they face 7 Raven-style IQ questions. They are informed that one of the tests will be drawn for payout, and that they should do their best on both tests to maximize their payoff. Both tests are constructed such that questions follow a set order of difficulty (unknown to participants apart from in the Difficulty treatment). The first test is paid with piece rate incentives, and the second test participants are paid according to the treatment incentives described above.
Participants can choose to respond to the questions as they appear or move questions to the end of the test. After responding to each question, they are given up to 20 seconds to answer a set of questions regarding their experience solving the question: How difficult they found it, whether they are certain that they got it right, and if they completely guessed when answering it.
In each of the tests, after the four minutes run out or after answering all seven questions, participants are asked an incentivized measure of beliefs regarding number of correct answers. The also report how much effort they exerted when answering the questions. After completing the two tests, participants answer an end questionnaire that maps neuroticism, anxiety, stress and motivation as well as how familiar they are with these types of exercises. We also collect background questions e.g. on gender, age, geographical location, household income and educational attainment.
Control
Participants in the pure control condition are presented with piece rate incentives equivalent to 0.20GBP per correct answer in both Test 1 and Test 2.
Low incentives with cutoff
Participants face higher pressure by introducing a cutoff; if participants score less than the set cutoff of 5 correct answers they will earn zero, otherwise they earn 0.20GBP per correct answer.
High incentives with cutoff
Participants face the same cutoff, and pressure is increased even more by increasing the monetary stakes. Instead of earning 0.20GBP per correct answer, they will earn 5 GBP per correct answer, if they score equal to or above the cutoff.
Difficulty treatment
In this treatment we test whether knowing the level of difficulty of each question could mitigate the gender gap in performance under pressure. We keep the incentives and cutoff as in High incentives with cutoff, and show participants the level of difficulty of the question they are currently attempting, as well as a diagram with the overview of the difficulty level of all the questions in Test 2.
