Figure 1.
Exemplary trial procedure for a word (left panel) and a non-word trial (right panel).
Participants responded in the first half of the experiment to indicate that a word is presented by looking upward (downward) and to indicate that a non-word is presented by looking downward (upward). In the second half of the experiment this mapping was reversed.
Figure 2.
Vertical eye position (upper panel) and eye velocity (lower panel) as a function of time since fixation onset at 0 ms. Saccade onset was defined as the moment where vertical eye movement velocity exceeded the saccade threshold of 50°/s. The shaded area shows the time interval in which the stimulus word was presented.
Figure 3.
Filled circles represent the conditions in which participants responded with a downward eye movement to indicate that the stimulus was an existing German word; open circles show the saccadic latencies when participants responded with an upward eye movement. Error bars represent the 95% confidence intervals of the mean based on within-subject differences [36].
