Once coined the neglected anxiety disorder, research on social anxiety in the past decade has greatly increased, however many questions still remain. This chapter outlines progress towards answering some of these outstanding issues, presenting recent developments in social anxiety research. This includes an exploration of dispositional factors (i.e., evaluation fears and self-discrepancies) and cognitive biases (i.e., decision-making; attentional bias) to symptom maintenance and treatment outcomes in clinical and non-clinical populations. In addition, neural activity in socially anxious and non-anxious individuals during cognitive reappraisal is presented. Finally, we examined potential barriers influencing treatment-seeking behaviours in social anxiety

High and low socially anxious individuals were presented with depictions of various facial expressions or household objects, followed by an internal (vibration presented to the finger) or external probe (the letter "E"). Participants were told that the vibration signals physiological changes and were asked to detect both probes. High socially anxious individuals showed larger front-central N140 amplitudes in response to vibratory internal probes as compared to non-anxious controls. ERPs elicited by picture stimuli and external probes and reaction times in response to both probe types did not differ between high and low social anxiety individuals. Early somatosensory ERPs reveal an attentional bias for internal stimuli that does not appear in overt behavior.
