Abstract : The work at the Columbia laboratory concentrated on two matters: (1) expansion of the work that began last year aimed at uncovering the laws of spatial summation between and within members of parallel line sets with regard to the influence on the setting of visually perceived eye level (VPEL); (2) to begin work on the separation of components of the body-referenced mechanism and to determine their separate influence on VPEL. The work on summation was reported at 4 presentations at professional meetings in 1992 and a fifth set of experiments has been submitted for presentation in 1993. The completed experimental work on the body-referenced mechanism has been submitted for presentation in 1993, In addition to the above, at Columbia we have begun work in which eye movements are being measured (scleral search coil technique) in conjunction with variation of visual field pitch with the first interest in determining whether a subject's setting of eye level to VPEL is differently influenced by the visual field than is the discrimination of VPEL....
