Saccade contingent updating in virtual reality
This was done by measuring the sensitivity loss during saccade for face stimuli using two separate tasks.
In the first task, we recorded the subjective rating of the stimuli that were presented during saccade.
The study was conducted in accordance with university ethics committee requirements.
The subjects gave informed consent to participate and were rewarded with 7.5 Euro vouchers.

Lack of awareness of a stimulus briefly presented during saccadic eye movement is known as saccadic omission.
However, there is no general consensus about the domain and the underlying mechanisms of such sensitivity loss.
Some recent studies employing modern gaze-contingent paradigms have been focused on vision around the time of freely made eye movements in natural dynamic scenes .
However, such paradigms are not able to dissociate the sensitivity change during saccade from the forward and backward masking effects introduced by the pre- and postsaccadic retinal images.
The extension of the results from simple stimuli to more complex objects has been neglected.
In two experimental tasks, we measured the subjective and objective awareness of a briefly presented face stimuli during saccadic eye movement.
