Frank observes and tracks Garrett's behavior for four days to determine how often he actually does leave his materials behind. He then introduces a required assignment book strategy to increase his ability to keep track of his class materials. Frank continues to observe Garrett's behavior. However, under the assignment book strategy, Garrett's behavior does not change. Frank decides that he will also require that Garrett obtain signatures from his teachers and parents in his assignment book and observes improved behavior. After four weeks, Frank removes the required assignment book and signature and observes and records Garrett's behavior for a week. If Frank's study is typical, what would one expect regarding Garrett's behavior after the requirement of the assignment book was taken away?
◦ He will now forget his things less than both before the assignment book and while he used the assignment book.
◦ He will now forget his things more often than before he started using the assignment book.
◦ He will now forget his things more often than while he was using the assignment book but less than before he started.
◦ His forgetting will substantially decrease and he will continue to use the assignment book.
