Feedback4 Specs (programmer: ED)

Stimuli

Use 24 new (not used in FB3) face-name pairs.

Summary of Design

Subjects get one presentation of entire list in random order. Then they get a test on everything (T1). Then they get two more tests (T2, T3) on everything that they get wrong on T1. There are 4 within-subject feedback conditions (assigned only to word pairs that elicit errors). One week later they are tested on all 24 face-name pairs.

Day 1

Phase 1: Presentations. Present face-name pairs in random order, for 6 seconds with 2 seconds between pairs.

Phase 2. In a new random order, run through the list, presenting faces and requiring subject to type in the name. Do not require confidence judgments in this experiment. Do the following as a function of subject’s response correctness:

Correct resp: Say “Correct!” for one second, and continue to next face.

Incorrect resp:

Randomly assign subjects to conditions “Blank”, “Test2FB”, “Test1-3FB” and “FullFB”

Blank: Present 2 seconds of blank screen as feedback for all three tests.

Test2FB: Present Blank on tests 1 and 3, and full feedback on test 2.

Test1-3FB: Present Blank on test 2 and full feedback on test 1 and 3.

FullFB: full feedback on tests 1, 2 and 3.

Phase 3. In a random order, run through just the items the subject got wrong in Phase 2 Test. Feedback is determined by the conditions assigned during Phase 2.

Phase 4. In a new random order, run through just the items the subject got wrong in Phase 2 Test. Feedback is determined by the conditions assigned during Phase 2.

Day 2

Subject returns 1 week later and is tested on ALL the faces in a new random order.
