Individual Differences in Working Memory Capacity Are Unrelated to the Magnitude of Benefits from Object- and Dimension-Based Retro-Cues

Previous studies have associated visual working memory (VWM) capacity with the ability to use internal attention. Internal attention’s effect on VWM has been studied mostly using object-based retro-cues, which can direct attention particular objects. In addition, by dimension-based retro-cues recent found that directing a feature dimension in improve recall performance. Although mechanism of for over ten years, no study date investigated relationship between and benefits retro-cues. The present aims explore individual differences their dimension- We first measured participants’ then asked them conduct cue task an task. performed better than low-VWM-capacity participants both tasks. although we identified certain RCBs obtained from cues, did not find any significant correlation magnitude RCB object- or cues. These results suggest is related RCBs’ magnitude, thus storage are independent mechanisms. Moreover, who benefitted most also color reports; however, this pattern was orientation report trials. This finding suggests partly overlapping two retro-cue types. provides evidence process.
