Dynamic and chaotic audiovisuals increase spectator attention, but inhibit conscious processing


According to a study conducted by the UAB and the UPO, scene changes diminish a spectator's blink rate, producing an increase in attention. 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 publishd 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 analysing brain synchronisation associated with scene changes, researchers concluded that the active brain networks are more intence after a scene change than before. From the point of view of synchronisation, 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.

Participating in the research were  professionals from Ràdio Televisió Espanyola (RTVE), coordinated by the Institut RTVE. The research was developed by Celia Andreu-Sánchez and Miguel Ángel Martín-Pascual from the Neuro-Com Group of the Department of Audiovisual Communication and Advertising, Universitat Autònoma de Barcelona, and by Agnès Gruart and José María Delgado-García from the Neuroscience Unit of the Pablo de Olavide University, Sevilla.

Iberian Peninsula, last refuge of the European lineage surviving the Ice Age

A study with the involvement of CEPAP-UAB has identified in the Iberian Peninsula a genetic lineage with two lineages which survived in Western Europe at the end of the Ice Age, one of which was considered to have disappeared 14,000 years ago. This dual lineage survived through the hunter-gatherers of Balma Guilanyà (Lleida, 12,000 years ago) and in the first Iberian Neolithics. Read more
