Abstract

'Change blindness' is the failure to detect substantial changes in the visual field that normally would be noticed easily. This effect is of interest as by making comparisons with change detection, it may be informative of the brain activity that occurs during visual awareness. This paper proposes a wavelet coherence analysis for measuring the degree of synchronisation of multi-channel electroencephalograph (EEG) signals during experiments of change detection and change blindness in picture pairs presented between blank inter-stimulus intervals. The magnitude of wavelet coherence is found to exhibit significant differences between the hit and miss visual states. The ANOVA test verified the statistical significance of coherence differences (p less than 0.01) between hits (change detection) and misses (change blindness) in cross-channel synchronization.
