Cognition in the bisection task.
Bisecting a visually presented stimulus is a sensitive test for attentional and motor biases in both healthy and brain-damaged participants. There are, in addition, perceptual effects on performance and several idiosyncratic biases. Experiments that manipulated the stimulus attributes have suggested that higher-level cognitive processes can also influence bisection accuracy. These observations encourage a wider diagnostic use of the bisection procedure.
