  abstract  = {Social attention is a ubiquitous, but also enigmatic and sometimes elusive phenomenon. We direct our gaze at other human beings to see what they are doing and to guess their intentions, but we may also absorb social events en passant as they unfold in the corner of the eye. We use our gaze as a discrete communication channel, sometimes conveying pieces of information which would be difficult to explicate, but we may also find ourselves avoiding eye-contact with others in moments when self-disclosure is fear-laden. We experience our gaze as the most genuine expression of our will, but research also suggests considerable levels of predictability and automaticity in our gaze behavior. The phenomenon's complexity has hindered researchers from developing a unified framework which can conclusively accommodate all of its aspects, or from even agreeing on the most promising research methodologies. The present work follows a multi-methods approach, taking on several aspects of the phenomenon from various directions. Participants in study 1 viewed dynamic social scenes on a computer screen. Here, low-level physical saliency (i.e. color, contrast, or motion) and human heads both attracted gaze to a similar extent, providing a comparison of two vastly different classes of gaze predictors in direct juxtaposition. In study 2, participants with varying degrees of social anxiety walked in a public train station while their eye movements were tracked. With increasing levels of social anxiety, participants showed a relative avoidance of gaze at near compared to distant people. When replicating the experiment in a laboratory situation with a matched participant group, social anxiety did not modulate gaze behavior, fueling the debate around appropriate experimental designs in the field. Study 3 employed virtual reality (VR) to investigate social gaze in a complex and immersive, but still highly controlled situation. In this situation, participants exhibited a gaze behavior which may be more typical for real-life compared to laboratory situations as they avoided gaze contact with a virtual conspecific unless she gazed at them. This study provided important insights into gaze behavior in virtual social situations, helping to better estimate the possible benefits of this new research approach. Throughout all three experiments, participants showed consistent inter-individual differences in their gaze behavior. However, the present work could not resolve if these differences are linked to psychologically meaningful traits or if they instead have an epiphenomenal character.},
