A previously demonstrated reversal of correlation between spiral after‐effect and sedation threshold in psychosis was confirmed, psychotics ranging in performance on these tests from High ST/Low SAE to Low ST/High SAE. Progression along this continuum was accompanied by a progressive change in the degree and kind of thought disorder present, as assessed by an object sorting test of conceptual thinking. Psychotics with high sedation thresholds produced a greater number of incorrect sortings than those with low thresholds. A negative correlation was also found between spiral after‐effect and overinclusive thinking. Some of the relationships between sorting test response and sedation threshold/spiral after‐effect performance were found to hold, not only in psychotics, but also in neurotic and normal individuals.
