简要总结
Spaced Repetition training has been found to be more effective than massed repetition for individuals with aphasia. This study seeks to examine the relative efficiency of three kinds of spacing for picture-naming training: traditional random presentation, non-adaptive spaced repetition, and adaptive spaced repetition.
详细描述
Participants undergo a screening evaluation including the Quick Aphasia Battery (administered via teleconferencing software), and a preliminary picture naming test of approximately 300 pictures, used to select individual items for treatment. Participants then undertake online picture naming training for 30 minutes a day, over two weeks. Pictures are repeated according to three different schedules to be compared: random presentation, non-adaptive spaced repetition, and adaptive spaced repetition. We compare the number of pictures successfully learned and the verbal reaction time for the pictures assigned to the three conditions.
