Abstract:
The subject of enquiry is the effect of high intensities of ambient luminance on task performance by human subjects, and the task employed, the detection of transient light signals in an illuminated display encompassing the whole of the subject's visual field. Experimental conditions were designed to test one particular prediction from previous work, that high intensities of environmental stimulation tend to reduce the range of cues utilised from the environment in performance of a task. ln the case of high intensities of luminance the prediction would be of a reduction in the size of the visual field, or 'tunnel vision'. The data produced does not bear out this prediction. Subjects show a decreased consistency of response when observed under the higher intensities of luminance so that their detection rate for peripheral signals is comparatively lower than for other intensities, but not in a sufficiently clear-cut fashion to be 'tunnel vision' as predicted.
