Valence and arousal relaxation towards an affective baseline. Mean values of valence and arousal (after correcting for individual baselines) in status updates following a preceding one generated Δt seconds before. Lines are aggregated by the emotions expressed in the first message to illustrate relaxation trends. Means are calculated over a rolling window of size 15 (seconds) over all status updates of all users and plot up to a maximum Δt of 300 seconds. Relaxation happens homogeneously above and below the baseline for both valence and arousal
