Visualization of the experimental set-up and results. Note. Left: Schematic depiction of the experimental setup. The participants’ hands were placed on the response keys at the respective ends of the keyboard. In the barrier condition, a black and opaque barrier was placed in the middle of the keyboard, lining up with the screen center, visually separating both halves of the keyboard but not the view of the screen. Right: Mean response–response binding effects for response times as a function of barrier (no barrier vs. barrier). Error bars depict the standard error of the mean. Binding effects are calculated as the advantage of probe Response A repetition (vs. probe Response A change) in probe Response B repetition trials minus the advantage of probe Response A repetition (vs. probe Response A change) in probe Response B change trials: [AcBr − ArBr] − [AcBc − ArBc]. *p < .05 indicates that binding effects differ significantly from zero
