In this table, Pearson's correlations between memory performance and features of the retention interval are shown. MAAS = Mindfulness Attention and Awareness Scale; Daydream frequency score = total score from the daydream frequency subscale of the Imaginal Processes Inventory. Boldface highlights statistically significant values.
