Rothkegel et al. 18 The saccade latencies of Experiment 3 were rather similar between the different pre-trial fixation times. There was a clear difference between the three lowest pre-trial fixation times (mean saccade-latencies of 315, 320 & 321 ms) compared to the three longer pre- trial fixation times (mean saccade-latencies of 365, 352 & 371 ms). Thus somewhere around 75 ms seems to be the lowest pre-trial fixation time to produce an influence in viewing behaviour. Experiment 3 was conducted to investigate the minimum pre-trial fixation time necessary for a reduction of the early central fixation bias. All pre-trial conditions showed a similar behavior with a tendency of an early CFB as measured by the DTC.
