 Social anxiety is strongly associated with self-perceived blushing, weakly associated with blushing as measured by physiological indices such as temperature and blood flow to the cheeks and forehead, and moderately associated with observed blushing.The relationship between physiological blushing and self-perceived blushing is small among those high in social anxiety, indicating that individuals with high social anxiety may overestimate their blushing.That social anxiety is associated most strongly with self-perceived blushing is also important for cognitive models of blushing and social anxiety, indicating that socially anxious individuals use both internal cues and other types of information to draw conclusions about how they are coming across.
