Fig. 10. Memory precision depends on task relevance.

(A) The cued item was remembered significantly better than items in a baseline condition where no cue was present, with a corresponding cost in memory precision for the less task-relevant items, in the trials where a cue was present. Errorbars are SEM. **P<0.001, *P<0.01. (B) Fractional difference in precision between the trials where a cue was present and the baseline condition. Gain in memory precision for cued items (light shade), and a cost for the uncued ones (dark shade) was observed at all possible serial positions of the cued and the tested item.
