Abstract
A
currently favoured cognitive model of the abnormal behaviours and experiences
characteristic of schizophrenia suggests that they may be linked to
a disturbance in the effects of context. This presentation reviews some
of the relevant literature, noting the wide range of experimental paradigms
that have been employed. This range of paradigms is both a strength
and a potential weakness of the literature since it raises complex issues
of definition and the need to distinguish the various ways that context
may influence behaviours. This influence may be crucially dependent
on specific task parameters. Despite this, a number of schizophrenic
symptoms can be plausibly related to changes in the way that context
operates: delusions, disorganisation, hallucinations, and the loss of
a sense of personal identity. Potential links with the neural bases
of the disorder are indicated.
