Note. Experiments 1–8 included high-salience targets to calibrate the low-salience targets. However, since the dual-target trial counts were matched to the number of low-salience single-target trials, we did not analyze the two-target effects of salience, nor explore interactions between salience and other factors such as frequency or time limit. We provide the data here for completeness.
