EEG-based neural activity for decoding situation awareness at different levels.
Situation awareness (SA) is the ability to perceive, comprehend and project environmental information. Neural activity is closely associated with SA. However, it remains unclear how neural activity represents SA at different levels. Here, three tasks were used to assess SA at three levels, behaviour...

Neural activity is closely associated with SA. However, it remains unclear how neural activity represents SA at different levels. Here, three tasks were used to assess SA at three levels, behavioural and electroencephalogram data were collected. Relationships between SA and neural activity were explored through comparisons of EEG power between high and low SA. For each SA level, EEG power significantly differed between high and low SA. Brain region-based analyses further revealed neural activities originating from distinct brain regions were recruited to represent SA at different levels. These EEG pattern features differed between high and low SA could be used to decode SA with the KNN (k-nearest neighbour) classifier. The present study marked a significant step in augmenting our understanding of the neural mechanism that characterise SA. PRACTITIONER SUMMARY: This study explores how neural activity represents situation awareness at perception, comprehension, and projection levels using 64-channel EEG data from 28 participants. Significant EEG power differences and regional neural activities were identified, and KNN successfully decoded SA. Findings enhance understanding of neural mechanisms in SA processing. pubtype: Academic Journal doctype: pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
