RESCUE research on social media use in emergencies

WP 5: Case Study: Psychophysiological reactions to using social media in emergencies

This subproject investigates in a laboratory setting psychophysiological and usability aspects of social media emergency communication tool developed within WPs 2, 3 and 6. Goals are to provide communication solutions tested for subjective (survey) and objective (psychophysiological reactions) user-friendliness, and scientific articles presenting the results. Focus groups are emergency professionals and news journalists, as well as crisis information officers. The solutions used in the study, and invited groups of professionals, are defined in collaboration with the subprojects mentioned above. The study is carried out at the MediaCity Content Testing Lab. Participants are presented to a stimulus in which they can actively take part. The software used for showing the stimulus enables the researcher to predefine specific areas of interest. Physiological measurement include cardiovascular (heart rate), electrodermal (sweat gland response), and electrocortical reactions (electroencephalogram), measured with a headset and hand sensors. Visual data (eye tracking saccades/fixation points) is measured with a remote tracker. A survey and a structured interview after the test session are used to further verify that the individual reactions are linked to the predefined specific areas of interest in the stimulus, not to background noise.
