Subjects then completed six periods of performing the decoding task and receiving feedback.7 After receiving their feedback for the sixth period, they were informed that the work periods were over, and that they had only to complete a final questionnaire. Once subjects turned in their final questionnaire, they were paid the sum of their wages for the six work periods. On average, the experiment took between 90 and 105 minutes to complete, and subjects were paid an average of $16 for participating.
