Visual illustration of both the block and linear mixed-effects models (LMMs) data from Experiments 1 and 2 with Block and Trial number on the x-axis and the N1-P1 peak-to-peak amplitude difference voltage on the y-axis. A Block LMM data, for both groups (green EM, blue HC) in Experiment 1. B Trial LMM data, for both groups (same colors) in Experiment 1. C Block LMM data, for both groups (same colors) in Experiment 2. D Trial LMM data, for both groups (same colors) in Experiment 2. Please note, that trials were grouped into bins of ten trials for both trial models (B and D) to facilitate visual inspection by reducing trial-to-trial variability
