The stimuli and procedure used in Experiment 2. All N items were initially stationary for N s then started to move. The target would change its state at a time that was randomly selected between the 2nd and 6th second (here, the closed book becomes an open book). Os were asked to respond as soon as they detected the target. Once a response was made, all items would be replaced by empty squares and Os would use the mouse to indicate the prior location of the target. All items would also turn to empty squares after they had moved for 8 s if Os did not make a response
