Abstract: This paper investigates the utility of EEG signals in suicidology, particularly for detection of suicidal ideation through data analysis of EEG signals elicit by reading of text notes, which may indicate genuine suicide attempt or a hoax suicide note. The role of emotion, attention, and memory in detection of suicidal ideation through perusal is studied. Also, the discriminatory role of alpha waves and beta waves is studied. Our study provides an important and interesting conclusion that prior experience or conditioned training in detection of suicide notes is not beneficial in discriminating between genuine and hoax suicide notes and that the brain signals are more discriminatory in participants with no prior experience or conditioning. Quantitatively, our results indicate that the beta waves in EEG channels related to memory can provide classification accuracy of more than 70%.
