Abstract : Seventeen graduate and undergraduate students participated to various degrees in different phases of the research. Several, more extensively involved, regularly joined in laboratory meetings, ongoing discussions, and formulation of research designs and plans in addition to participating in the construction of apparatus, and collection and processing of experimental data. Others were essentially focused on data collection and processing. The experiments were all concerned with the visual perception of elevation, most particularly with analysis of the significant influence of visual pitch. on the elevation of visually perceived eye level (VPEL). An undergraduate's honor's thesis involved measurements of both VPEL settings and manual matches to targets through a range of elevations above and below VPEL, and showed that the influence of the visual field on VPEL was part of a shift of the entire dimension of perceived elevation along with closely related sensorimotor mislocalizations. A graduate student's master's thesis measured the relation between VPEL and the perception of visual pitch over a range of pitches on a large group of subjects; the mechanisms for both are at most minimally connected.
