Abstract: | An inexpensive head-mounted scene holder is described. In contrast to the usual biteboard/fixed-head approach, the present apparatus allows head movements without introducing substantial artifact. This enables eye movement investigations of brain-damaged or psychiatric subjects who often cannot maintain prolonged head immobility; also, the unit makes possible subjects’ verbal reports coincident with visual scanning. |
