Schematic description of the visuospatial working memory task. The stimulus was presented with five BBQ pork buns randomly spaced across a screen with black background. A cue stimulus was first presented for 1 s. After a delay of 5–8 s, a probe stimulus was presented for 1 s and the participants were instructed to judge whether the probe stimulus was the same as the cue stimulus by pressing the button with the right index or the middle finger. The difficulty level of the task was varied by 1–3 buns being moved in the probe stimuli compared to the cue stimuli. The inter‐trial interval lasted 13–16 s randomly.
