Abstract
Background—There is a growing recognition that individuals at clinical high risk need
intervention for functional impairments, along with emerging psychosis, as the majority of clinical
high risk (CHR) individuals show persistent deficits in social and role functioning regardless of
transition to psychosis. Recent studies have demonstrated reduced reading ability as a potential
cause of functional disability in schizophrenia, related to underlying deficits in generation of
mismatch negativity (MMN). The present study extends these findings to subjects at CHR.
