In visual working memory (VWM) tasks, participants’ performance can be improved by a retro-objectcue.
However, previous studies have not investigated whether participants’ performance can also
be improved by a retro-dimension-cue. Three experiments investigated this issue. We used a recall
task with a retro-dimension-cue in all experiments. In Experiment 1, we found benefits from retrodimension-cues
compared to neutral cues. This retro-dimension-cue benefit is reflected in an increased
probability of reporting the target, but not in the probability of reporting the non-target, as well as
increased precision with which this item is remembered. Experiment 2 replicated the retro-dimensioncue
benefit and showed that the length of the blank interval after the cue disappeared did not influence
recall performance. Experiment 3 replicated the results of Experiment 2 with a lower memory load.
Our studies provide evidence that there is a robust retro-dimension-cue benefit in VWM. Participants
can use internal attention to flexibly allocate cognitive resources to a particular dimension of memory
representations. The results also support the feature-based storing hypothesis.

Encoding specificity instead of online integration of real-world spatial regularities for objects in working memory
Liu, Xinyang; Liu, Ruyi; Guo, Lijing; Astikainen, Piia; Ye, Chaoxiong (Association for Research in Vision and Ophthalmology (ARVO), 2022)Most objects show high degrees of spatial regularity (e.g. beach umbrellas appear above, not under, beach chairs). The spatial regularities of real-world objects benefit visual working memory (VWM), but the mechanisms ... -
