Abstract:
Evidence of task reliability is critical for use of measures of attention in studies of individual differences among members of clinical populations. Test-retest reliability of several measures of attention and information processing was studied in 14 chronic schizophrenics. Performance was stable over a 6-month period, except for decreases in reaction time.
