Experiment 5. (a) Accuracy of membership task performance for the different trial subtypes, illustrating implicit statistical effects of ancestor (dark blue-red bars) and range effect (grey-green bars). Difference is highly significant (p < 0.001) in both. (b) Correct (green) and Incorrect (red) trial reaction times (RTs) for each subtype illustrating no speed-accuracy trade-off, and a flip between speed of correct and incorrect responses between trials of NEW = base and baseline to SEEN = base and NEW = out. (c) Graded ancestor effect: X-axis as in Fig. 11c and d; dot colors represent trial subtypes as in (a)
