"Manifest" anxiety, neurotic anxiety, and the rate of conditioning.

Abstract
"The validity of the Taylor Scale of Manifest Anxiety was examined with a view to reconciling the contradictory results of the studies of the relation between anxiety and the rate of conditioning . . … The results indicated that different scores on the scale do not represent different degrees of manifest anxiety, though the scores within a limited range (19 to 33) are more likely to be associated with a clinical diagnosis of "anxious" than are scores above and below this range."
