Dynamic and chaotic audiovisual editing inhibits spectator's blink rate, increases attention

According to a study conducted by the UAB and the UPO, scene changes diminish a spectator's blink rate, producing an increase in attention. The results of the study demonstrate that a dynamic and chaotic audiovisual editing causes more activity in the visual processing areas, while continuous and orderly editing produces more cognitive processing activity.

Scene changes inhibit a spectator's blink rate, thus increasing their attention. It also produces a flow of brain activities from the occipital lobe towards the frontal lobe. These are the conclusions reached by researchers from the Universitat Autònoma de Barcelona and the Pablo de Olavide University, Sevilla. The study, recently published in the journal Neuroscience, deals with what happens after the scene changes from a triple approach: frequency in blinking, electric activity in the brain and functional connectivity associated with the brain.

The research also concluded that the editing style influences a spectator's perception. Scene changes presented in a dynamic and chaotic style, such as video-clips, produce more activity in the visual processing areas when compared to more continuous and orderly scene changes. Likewise, the activity in frontal areas in charge of more complex processes is superior when the editing style is more continuous and orderly.

After analyzing brain synchronization associated with scene changes, researchers concluded that the active brain networks are more intense after a scene change than before. From the point of view of synchronization, there is no difference associated with the editing style.

Previous studies conducted by the same team had demonstrated that the editing style affected the blink rate of spectators. In this new paper, researchers conducted a detailed analysis of what occurs in the immediate second after a scene changes according to the editing style.
