As crisscrossing of optic fibers blur the possibility of eyedness as an indicator of lateralization, the other two relatively influence-free measures (from cultural sanctions) have emerged as the predictors of schizophrenia and depression.
Porac & Coren (1976), who constructed a taxonomy for eyedness tasks based on performance similarities, also identified the monocular task as one of eight tasks.
Thus we might hypothesize four (or more) types of individuals based on their consistency of performance on a single eyedness task: (1) those who consistently use the right eye; (2) those who usually use the right eye but occasionally use the left; (3) those who usually use the left eye but occasionally use the right; and (4) those who consistently use the left.
At this point in time we were still subscribing to the all or none theory of eyedness (either all left or all right).
Coren & Kaplan, 1973; Porac & Coren, 1981) reporting mixed laterality on eyedness tasks is based on multiple trials within a single session.
For the time being, until some other procedure is found, the authors must recommend only a single observation per day for eyedness tasks.
Thus we expect studies with only a few observations of eyedness all done in a single session to risk perseveration errors.
