• International Classification of Vestibular • Internal (self) or external (surround) • Feeling of postural instability (e.g., swaying or • Disturbed sense of spatial orientation Bisdorff, et al., J Vest Research, 2009 1871 Westphal - Die Agoraphobie (fear of squares) Patients find it impossible to cross open squares and walk along certain – Legrande du Saulle - concept of ‘fear of fear’ streets. Fear restricts their mobility, [but] they insist that they are not aware of any reasons for their anxiety. It seems to arise as an alien force as soon as a square is crossed or approached. With the anxiety, – Lannois and Tournier - agoraphobia occurs in as part of one process, occurs the thought of not being able to cross individuals with pre-existing psychic anxiety, and is and a perception of an enormous expanse of space.

No differences (eyes closed). • Shorter response latencies, more postural corrections for subjects with high anxiety. • Subjects with anxious traits were more strongly affected by erroneous visual stimuli.
