saccadstorlek

Saccadstorlek refers to the amplitude or extent of a saccade, which is a rapid, ballistic movement of the eyes. Saccades are involuntary eye movements that allow us to shift our gaze quickly from one point of interest to another. The size of a saccade is determined by the distance between the initial fixation point and the new target location. Larger saccades are used to cover greater visual distances, while smaller saccades are used for fine adjustments or to scan within a limited visual field.

The magnitude of a saccade can vary significantly depending on the task and the individual. For example, when reading, saccades are typically small and directed forward along the text. When searching for an object in a cluttered scene, saccades may be larger and more exploratory. Factors such as attention, visual salience of the target, and cognitive load can all influence saccade size. Researchers study saccadstorlek to understand visual attention, eye movement control, and various neurological or oculomotor disorders. Abnormal saccade sizes can be indicative of conditions affecting the visual system or the brain.
