Stimuli used in experiments 1 and 2, and results. Top panels: stimuli and an example background used in experiment 1 and 2. Target types had: black and white stripes (S), interval stripes of gray, white, and black (IS), uniform camouflage gray (G), uniform conspicuous white (W), background matching (B), and disruptive (D) coloration (see main text for details). All target types except W have the same average luminance as the background. Middle and lower panels: the mean number (plus 95% confidence interval (CI)) of successful captures (left panels) and missed attempts (right panels) of the different target types in experiment 1 (moving targets), and medians (plus interquartile range (IQR)) for experiment 2 (stationary targets).
