"Participants completed either the spaced practice schedule or completed the massed practice schedule. Each of the 24 items first received an initial study trial in the spaced practice schedule. On an initial study trial, they were presented on the left side of the screen and the target English translation appeared on the right side of the screen for 10 seconds. All items were presented for initial study. There were three test-restudy practice trials for each item after that. The Swahili word was presented alone and participants had eight seconds to enter the English translation in a text box. After the response box was removed from the screen, the Swahili and English words were presented together for a four second restudy opportunity."
