Sentence examples for saccade from inspiring English sources
'saccade' is a correct and usable word in written English
You can use it to refer to a quick movement of the eye, such as when reading. For example: "The motions of the reader's eyes show an obvious pattern of saccades as they move down the page."
noun
A sudden jerking movement.
Second, an active blanking-off process, known as saccadic suppression, occurs, and this blocks vision for the first part of each saccade.
The small flicks mentioned above are essentially the same as the larger movement made when the two eyes fixate (fix on) a light when it suddenly appears in the peripheral field; this is given the general name of the saccade, to distinguish it from the slower movements occurring during convergence and smooth following.
Thus, humans have no basis for detecting the change that each saccade causes.
If observers are presented with alternating views of the same scene, but with one substantial change between views, it takes many presentations before the change is detected if a blank period equivalent to a saccade is introduced between each view.
If a moving light suddenly appears in the field of view, and if its rate of movement is less than about 30° per second, the response of the eyes is remarkably efficient; a saccade brings the eyes on target, and they follow the motion at almost exactly the same angular velocity as that of the target; inaccuracies in following lead to corrective saccades.
The movements of the eyes when they converge onto a near object are in remarkable contrast to the saccade; the angular velocity is only about 25° per second, compared with values as high as 500° per second in the saccade.
The saccade-and-fixate strategy is the way humans take in information from the world most of the time.
She can read and even perform some complex daily activities (like making herself a cup of tea) — but only because she has learned to make saccade-like motions with her head.
Between saccades, the eyes are held stationary in fixations.
Saccades can be reflexive in nature for example, when an object appears in one's peripheral field of view.
However, as Russian psychologist Alfred L. Yarbus showed, saccades are often information-seeking in nature, directed to particular objects or regions by the requirements of ongoing behaviour.
