Yes. it was harder for me to observe a alteration in the image when it flickered because it was harder for me to keep focal point on the alteration I was supposed to be looking for.

The spark status is the visual aspect of a clean grey box or a mask in between images presented. The clean image swamps the local-motion signal that would typically be caused by a alteration but our attending is non affected by it. the mask prevents automatic sensing of alteration. Change is detected by slower. higher-level procedure by seeking the scene exhaustively until you find the changed object. In the no spark status the type of hunt scheme normally used is the hunt for the local-motion signal caused by alteration of object.

With this type of scheme it is easy to observe alteration when it is happening and when there is besides no alteration. In the spark status the normally used scheme is seeking the scene. object by object until the alteration in object is found. Advanced Question The reaction clip reported is to demo how long that it took to place the alteration in object per exposure. Trouble between the conditions can be observed and examined by entering the reaction clip of the experiment. Flicker conditions are the same as the drive conditions stated above. Looking off from the route to look at something else is the same as seeing a scene so looking at a clean field followed by a different scene. You may non be able to detect the alteration right off due to response clip and you might hit person or another vehicle because of the alteration of scene.
