Bluetooth-sensed social presence is associated with immediate vigor and delayed fatigue: A multi-method time series analysis
Recent Publication
A new study by Dr David Willinger MSc and Professor Stefan Stieger from the Department of Psychological Methodology at KL shows how social proximity affects our everyday lives. Using Bluetooth signals as a measure of social presence and over 3,700 recorded moments of emotional wellbeing, the researchers found out: People who are close to other people feel more alert and less depressed in the short term, but become more tired later on. What is particularly exciting is that the strongest effects only occur a few hours after the contact. It was also found that energised states last longer than tired phases.
