VISUAL AND TACTUAL INTERACTION IN JUDGMENTS OF VERTICAL

Four field-dependent and four field-independent Ss set a comparison bar to the apparent vertical while receiving either veridical or nonveridical reference information. Two intranodal and two inter modal conditions were used. Visual settings were significantly more accurate than tactual settings regardless of the reference modality used. The visual reference significantly increased the error of the tactual setting over that using a tactual reference. The differences between the groups were not statistically significant. The nature of the intermodal interaction needs further clarification. © 1969, Psychonomic Journals, Inc.. All rights reserved.
