Abstract: | The present study examined the extent to which differences in strategic encoding and contextual retrieval account for the
relation between individual differences in working memory capacity (WMC) and variation in episodic recall. Participants performed
a continual distractor task under either incidental- or intentional-encoding conditions. High-WMC individuals outperformed
low-WMC individuals across both encoding conditions and, notably, to a greater degree in the intentional-encoding condition.
These results suggest that WMC differences in episodic recall are likely due to a combination of differences in both contextual-retrieval
and strategic-encoding processes. These findings are consistent with prior work showing that high-WMC individuals are better
at engaging in strategic-encoding processes during the presentation of items than are low-WMC individuals and are better at
using contextual cues to focus the search on correct items during retrieval. |
