replicated our observations from Experiment 1 and demonstrated that a reduced CFB was not exclusively generated by the extreme starting positions used in Experiment 1. 

## Experiment 3 

The results from Experiment 1 and 2 showed that a pre-trial fixation time of 125 ms was enough to reduce the central fixation bias on early fixations. The difference of the CFB between pre-trial fixation times larger than 125 ms was relatively small. To investigate the minimum pre-trial fixation time for a substantial CFB reduction, we conducted a third experiment with pre-trial fixation times ranging from 0 to 125 ms in six equidistant steps. We changed the between-subject design of pre-trial fixation time to a within- subject design to reduce the influence of individual participants (cf., Exp. 1). Hence, every participant was tested with all pre-trial fixation times. Since effects were maximal
