Figure 7. Individual Data From Each Data Set Contributing to Figure 6.

Note. The effect of exogenous factors on NDT is illustrated by the positively sloped lines connecting the markers in the upper panel. The absence of an effect of endogenous factors is illustrated by the flat or inconsistent lines connecting the empty and full markers in the lower panels. (A). Brightness (black to grey circles and diamonds: bright to dim in Bompas & Sumner, 2009b and the free choice data); magnocellular versus koniocellular (grey to magenta circles: achromatic to chromatic in Bompas & Sumner, 2009a); Size; black to green: 16–1° wide stimuli from Experiments 1 (empty circles), 2 (full circles), and 3 (diamonds) in Buonocore & McIntosh, 2012. (B) Brightness (black to grey diamond and circles: bright to dim from the manual shape-discrimination stop-task data set, local and online experiments). (C) Instructions (empty to full grey circles: ignore to stop blocks from Campbell et al., 2017; black circles and diamonds: Experiments 1 and 2 in Bompas et al., 2020); Postsignal slowing (empty to full dark blue: postsignal to postgo trials from monkey data; light blue circles and diamonds: unimodal and bimodal conditions in Boucher, Stuphorn, et al., 2007); Attention (empty to full green circles: ipsilateral to contralateral distractors from Buonocore & McIntosh, 2012). (D) Postsignal slowing (empty to full grey circles: postsignal to postgo trials from Campbell et al., 2017; light blue circles and diamonds: same from unimodal and bimodal conditions from Boucher, Stuphorn, et al., 2007); Instructions (empty to full red circles: fast to cautious blocks from the letter discrimination data set, T₀ pooled across ignore and stop trials that were interleaved within blocks). NDT = non-decision time; RT = reaction time. See the online article for the color version of this figure.
