The Trail Making Test and Canter Background Interference Procedure in screening for organicity in chronic schizophrenia: a preliminary report.
For 10 male organic chronic schizophrenics scores on the Trail Making Test and Canter Background Interference Procedure were compared. These patients had severe hyponatremia, a condition that results in brain damage. The hit rate for correctly classifying the oranicity was 100% on the basis of sequence binding on Trial Making B and 50% on Canter's procedure. The findings suggested that the Trial Making Test may prove useful in discriminating organic from nonorganic schizophrenics. Implications for research were discussed.
