ABSTRACT Questioning individuals about future behavior influences the subsequent performance of that behavior. This question-behavior effect may be enhanced when questions include positive self-identity prompts. To evaluate the effectiveness of this intervention in a testing context, we randomly assigned examinees to one of three conditions prior to completing a low-stakes test: answering five questions regarding intended effort prior to the test, answering five questions regarding intended effort that referenced positive self-identity prior to the test, or a control condition. We then administered two multiple-choice tests and collected two measures of test-taking effort: self-reported effort and response time effort. Answering questions about effort prior to completing the tests resulted in higher self-reported effort and perceived test importance. Moreover, in the question conditions, significantly fewer examinees were identified to be filtered from the dataset due to low effort. The easy strategy of asking examinees to report their intended effort appears to increase test-taking effort.
