Behavioural data analysis: synergistic disappearance of targets across quadrants. (a) The number of PFI events per trial, (b) the mean duration per PFI event and (c) total duration of PFI per trial, as a function of the number of invisible targets (nPFI). All panels display both observed (blue) and shuffled (grey) data. For the observed data, error bars represent 1 SEM, corrected for within-participant comparisons (Cousineau 2005). For the shuffled data, we first computed the SEM within each shuffled data set across participants. Then, as the error bar, we show the mean of the SEM across 1000 shuffled sets. (d–f) Slope of the linear fit for each of the PFI variables in a–c as a function of nPFI for the observed (blue line) vs. the shuffled data (1000 sets, grey histogram).
