TIME PERCEPTION IN A NEGLECTED SPACE

WE have studied the distortion of perceived time in a patient with lef t neglect. This patient consistently overestimated the duration of sti muli in the neglected space. Overestimation was observed both with an interval comparison (300/700 ms) and with a time production (1 s) para digm. We suggest that encoding duration in the hundreds of millisecond s range is a process based on an internal clock mechanism. The functio ning of that clock varies as a function of the processing load.
