“…Similarly, Strong and Boers () reported that the retrieval condition led to more successful performance during learning (88%) than the trial‐and‐error condition (18%). Kasprowicz, Marsden, and Sephton () did not find a statistically significant difference between long and short spacing in learning phase performance (7‐day: 79.6%, 3.5‐day: 82.5%). However, a number of studies demonstrate that long spacing induces more errors during the learning phase than short spacing (e.g., Brown, Roediger, & McDaniel, ; Nakata & Suzuki, ; Nakata & Webb, ; Pashler, Zarow, & Triplett, ; Toppino & Gerbier, ).…”
