Figure 1.

Diagram demonstrating the selection of data points entering the expanded regression analyses. Dot positions (d1, d2, d3, …) changed every 100 ms in the experiment (black). Colored dots indicate times at which signal data points entered the analysis for a given time from dot position change (dot onset, shown exemplarily for 80 and 220 ms from dot onset). We only considered time points up to 200 ms before the response in each trial. Colored d1, d2, d3 above the points indicate the dot positions associated with the corresponding signal data points for the given time from dot onset. For each trial, these pairs of signal data and dot positions entered the expanded regression analyses.
