Is there a threshold for mental rotation?
Date of Original Version
A threshold-like nonlinearity was found in a mental rotation experiment designed for relatively heavy sampling of small angular disparities. The value of the threshold in this experiment appeared to be around 15°. Results of a control experiment were that subjects easily discriminated orientations differing by as little as 6° using the same stimulus materials. A threshold hypothesis represents one way to think about the flexibility and limitations of mental rotation performance. © 1986, Psychonomic Society, Inc.. All rights reserved.
