You are interested in enhancing learning. You decide to test the hypothesis that continual self-testing as part of the learning process can benefit the long-term retention of information. In this case, testing refers to learning the material to a 100% accurate level and then continuing to be tested on the material during later learning trials. You decide to compare participants in the self-test condition to participants who learned the material to the 100% level and continued to study the material but did not engage in ongoing self- testing. You test the long-term retention of the information for the two groups 1 week later. The data are shown on the right. Is there support for your hypothesis?
