The extraretinal signal for the visual perception of direction (original) (raw)

Abstract

The dependence of the perception of direction on two kinds of extraretinal signals was measured by asking Ss to indicate the position of a fixation target relative to the subjective straight ahead. Outflow was studied by making such localizations while the fixating eye was loaded by means of weights attached to a suction contact lens. Inflow was studied by making such localizations with brief test flashes to a passively rotated eye while the other eye fixated. Shifts in the perceived direction, of the fixation target were in line with predictions from outflow theory and not influenced by conflicting inflow signals.
