Figure 3. Schematic diagram of the proposed trial integration process.
Practice trials (dark gray rectangles) integrate (thick black line) in a transient memory store and only stabilize in a store that lasts across days when integration surpasses a learning threshold (light gray bar). Given insufficient training within the transient-memory period the trials do not persist across days (left panel)), but with sufficient training the trials are retained (middle panel). According to this idea, the 30-minute break disrupts learning because the transient memory has largely reset during this break (right panel).
