Abstract : Four unilaterally labyrinthectomized human Ss made judgments of the postural vertical in the presence of a tilted visual framework. In general, the estimates of postural verticality were not displaced in the direction of the injured side. The tilted visual framework did not have unusual effects on the judgments rendered Hence these Ss with one functional labyrinth did not demonstrate a less stable conception of verticality than previously observed 'normals.'
