The role of cognitive control in memory retrieval applications to schizotypy and schizophrenia

Individuals with schizophrenia have memory impairments. The experiments in this thesis were designed to determine whether these impairments arise from failures of cognitive control operations. Specifically, these experiments examined whether differences in target and non-target left-parietal old/new effects – a proposed neural correlate of strategic control over recollection - are predicted by schizotypy and/or schizophrenia symptomology. Correlations between schizotypy measures or symptom scores and how well people exercise control over retrieval of relevant information would point to one locus for memory problems associated with schizophrenia
