“…After the presentation of the retro-cue, the fixation dot remained for an interval of 500 ms (Delay2) until three masks were presented for 100 ms at the previous item locations. These masks, composed of randomly mixed black and white squares (24x24 matrix, 5.3ºx5.3º), were presented to reduce any potential contamination by visual sensory memory representations of the memory array onto the test array (Lepsien et al, 2005, Sligte et al, 2008, 2009, with no anticipated modulation of attentional effects at this temporal latency (Chiarella et al, 2023). Finally, a question was presented in one of the three item locations depending on the experimental condition.…”

Retrospective attention is involuntarily or voluntarily oriented to working memory (WM) contents. Previous research has not assessed voluntary attention ruling out the effects of involuntary attention. Furthermore, it is unknown whether the voluntariness of attention impacts differently on perceptual and semantic WM contents. To address this, reaction time and accuracy data from two retro-cueing experiments were modeled with a drift-diffusion model. Surprisingly, the voluntariness of attention did not interact with the WM content type. In turn, drift rates indicated that attention exerted greater retro-cueing effects on perceptual vs. semantic WM contents, and non‐decision times revealed effects only for voluntary attention. This evidences: first, that attention has a stronger impact on the quality of perceptual over semantic contents when they compete for WM storage; second, that voluntariness is crucial for retrieving WM contents in advance of decision-making; finally, the effects of voluntary attention can be independent of involuntary attentional orienting.
