Clark Honors College in partial fulfillment of the requirements for the degree of Bachelor of Science June 2014The presence of the testing effect in a retention interval of 8 hours is investigated in this study. Undergraduate students were told to remember a word list and were either given a test to study or re-read the word list before taking a recall test for these words 8 hours later. There was no difference in word recall accuracy for those who were given a test to study and who re-read the word list to study. The results showed that the testing effect was not present for a retention interval of 8 hours. This null effect is atypical to the robustness of the testing effect found in other studies that have a retention interval of at least 1 day.en-USAll Rights Reserved.PsychologyShort retentionCrammingLearning memoryMemory recallTesting effectThesis / Dissertation
