Figure Legend Snippet: A) The number of hits (correct responses), errors, misses and false alarms as a function of target-flanker distance with standard error of the mean (SEM) from a total of 64 target events per condition. B) Average proportion correct in different target-flanker distances fitted with a Gaussian function. 90% of the asymptote indicated as the critical spacing. Median (red dotted line) and 95% confidence intervals (grey area) of the critical spacings based on 1000 bootstrapped means. C) Average response time in correct trials across participants. D) Grand-average amplitude spectrum obtained by Fourier transform separately for each condition collapsed across occipital electrodes (P04, P08, P6, CP6, P8, P03, P07, P5, CP5, P7 Oz, POz, O2, Iz and O1). Amplitudes peak at simulation frequencies 10, 12 and 15 Hz, however, these peaks are more pronounced when stimulus-specific electrodes are chosen. Topographic maps of SSVEP amplitudes for each stimulus at simulation frequencies averaged across all subjects and conditions (electrode positions chosen for analysis indicated with circles). E) Average normalized target-related amplitudes from five highest amplitude electrodes for each frequency separately, fitted identically to the behavioural data with critical spacing (black dotted line). Median (red dotted line) and 95% confidence intervals (grey area) of the critical spacings based on 1000 bootstrapped means.
