Trial percentages for Ext-Ret were 46.9%+/−2.7 hits, and 41.5%+/−2.3 misses. Trial percentages for Int-Ret were 33.8%+/−2.5 hits, and 45.6%+/−2.2 misses. In general, memory performance was better for Ext-Ret than for Int-Ret (hits, p = 0.0002; misses p = 0.10). Thus, both RT and accuracy analyses indicate that encoding and retrieval conditions were more difficult for internal than external conditions.
