Abstract Share this page

A theoretical model was given for the size-weight illusion based on a principle of information integration. Judged heaviness of lifted weights was assumed to be an average of two pieces of information, weight and size, with the latter receiving negative weighting in the model formulation. Two experiments based on a Weight by Size design gave fair support to the parallelism prediction of the integration model. The hypothesis that Ss were really judging density was shown to imply a divergence prediction, contrary to the data. The theoretical analysis was generalized to include negative, positive, and comparative illusions; these were differentiated according to whether the contextual information was integrated with negative weighting, positive weighting, or served as a yardstick of judgment. This research was supported in part by NSF Grant GB-3629 to the senior author and Robert K. Young and in part by NDEA Title IV Fellowship No. 67-11070 to the junior author. The authors wish to express their thanks to Barbara Tabor for her assistance in collecting and analyzing the data and to Donald J. Foss and Merrill Garrett for their cooperation and comments. Portions of this research were reported to the Midwestern Psychological Association Meetings, Chicago, May 1969.
