TL;DR
Seasonal measures that reveal abnormalities during the acute psychotic episode and then return to normal levels during nonpsychotic, clinically remitted periods are called episode indicators, because they index processes that show acute disruptions during the psychotic period.
Abstract
In recent years, several researchers have proposed a distinction between vulnerability indicators (or markers) and episode indicators for schizophrenic disorders, based on whether an abnormality is present only during the active psychotic state or on a continuing basis (Zubin and Spring 1977; Cromwell and Spaulding 1978). Measures that reveal abnormalities during the acute psychotic episode and then return to normal levels during nonpsychotic, clinically remitted periods are called episode indicators, because they index processes that show acute disruptions during the psychotic period. Episode indicators would be expected to include (1) abnormalities that reflect processes immediately underlying the acute psychotic symptoms and (2) abnormalities that are secondary to disruptions associated with acute psychotic symptoms.

Empirical findings suggest that manipulation of procedural variables may differentially affect the processing efficiency of the cerebral hemispheres and indicate that a given pattern of visual-field asymmetry may be overdetermined by a multitude of variables interacting in complex ways.

Both schizophrenics and manics processed less information than depressives, and did not differ from each other, which suggests that reduced span may be a concomitant of psychoses characterized by distractibility and thought disorder, rather than a trait specific to schizophrenia.
