  1. Effects of target–distractor similarity (TDS), distractor–distractor similarity (DDS), and target presence on slopes over set size. The slopes were computed based on the transformed reaction time. Generalized eta square (ges) was computed as the effect size. Based on Bakeman (2005) a ges of 0.02 can be seen as a small effect, one of 0.13 as a medium effect, and one of 0.26 as a large effect
