DASPS: A Database for Anxious States based on a Psychological Stimulation
Anxiety affects human capabilities and behavior as much as it affects
productivity and quality of life. It can be considered as the main cause of
depression and suicide. Anxious states are easily detectable by humans due to
their acquired cognition, humans interpret the interlocutor's tone of speech,
gesture, facial expressions and recognize their mental state. There is a need
for non-invasive reliable techniques that performs the complex task of anxiety
detection. In this paper, we present DASPS database containing recorded
Electroencephalogram (EEG) signals of 23 participants during anxiety
elicitation by means of face-to-face psychological stimuli. EEG signals were
captured with Emotiv Epoc headset as it's a wireless wearable low-cost
equipment. In our study, we investigate the impact of different parameters,
notably: trial duration, feature type, feature combination and anxiety levels
number. Our findings showed that anxiety is well elicited in 1 second. For
instance, stacked sparse autoencoder with different type of features achieves
83.50% and 74.60% for 2 and 4 anxiety levels detection, respectively. The
presented results prove the benefits of the use of a low-cost EEG headset
instead of medical non-wireless devices and create a starting point for new
researches in the field of anxiety detection.Comment: 11 pages, IEEE transactions on SMC:system
