Individual differences in working memory capacity are unrelated to the magnitudes of retrocue benefits

Abstract Previous studies have associated visual working memory (VWM) capacity with the use of internal attention. Retrocues, which direct internal attention to a particular object or feature dimension, can improve VWM performance (i.e., retrocue benefit, RCB). However, so far, no study has investig...
