Scene complexity modulates degree of feedback activity during object detection in natural scenes
Fig 6
ERP results from the EEG experiment (Experiment 2).
Average ERP amplitude for animal (solid lines) and non-animal scenes (dashed lines) per condition for an occipital-peri-occipital cluster of EEG channels (Oz, POz, O1, O2, PO3, PO4, PO7, PO8) for the A) speed and B) accuracy trials. Shaded regions indicate SEM across participants. Significant differences between animal and non-animal ERPs (FDR-corrected) are indicated with thick black lines (also in C/D). C-D Animal vs. non-animal difference wave for each condition overlaid and statistically compared (FDR-corrected) for the speed A) and accuracy B) trials. Thick lines at the bottom of the graphs indicate significant difference wave deflections from zero, and shadings indicate S.E.M. Symbol markers indicate significant differences in difference wave amplitude between conditions, blue asterisk: HIGH vs. LOW; blue plus: HIGH vs. MEDIUM; green plus: MEDIUM vs. LOW.
