Delayed recall of a list was markedly poorer than story recall (d = \u22120.86), with 52% of the sample exhibiting \u2265 \u22121.0 SD deficits. Lastly, delayed free recall was worse than recognition memory (d = \u22120.25), with 24% showing a discrepancy of \u2265 \u22121.0 SD. These patterns did not consistently correlate with executive function scores.
