Final Test |
Study phase: Present all 30 facts in sentence format, in random order, with instructions to remember them for a later memory test. (fixed at 6 sec per fact x 30 facts = 3 min).
Test phase: Facts are in question format with 1-word answer. Presented 1 at a time in new random order, with instructions to type in correct answer. Allow unlimited time for response (but assume about 5 sec per response) (5 sec x 30 facts = 2.5 min)
Feedback:
Final test phase: Facts are in question format with 1-word answer (same as Test Phase). Presented 1 at a time in new random order, with instructions to type in correct answer. Allow unlimited time for response (but assume about 5 sec per response) (5 sec x 30 facts = 2.5 min). No feedback.
Total time to complete: Consent and instructions (3 min) + Study phase (3 min) + Test phase (2.5 min) + Feedback (3 min) + Final test (2.5 min) = 14 min.
Subjects: 100 lottery subjects per condition.
Expected Results:
Overall test performance:
Test performance similar for Condition 1 compared to Condition 2, and for Condition 3 compared to Condition 4.
Effect of feedback delay:
(1) If delayed feedback > immediate, then Conditions 2 and 4 > Conditions 1 and 3.
(2) If immediate feedback > delayed, then Conditions 1 and 3 > Conditions 2 and 4.
Effect of test delay:
(1) If delayed test > immediate, then Conditions 3 and 4 > Conditions 1 and 2.
(2) If immediate test > delayed, then Conditions 1 and 2 > Conditions 3 and 4.
Feedback Delay x Test Delay Interaction (potential simple main effects):
(1)
Delayed feedback > immediate, but just for immediate
test: Condition 2 > Condition 1
(2) Delayed feedback > immediate, but just for delayed test: Condition 4 > Condition 3
(3) Immediate feedback > delayed, but just for immediate test: Condition 1 > Condition 2
