Series. The scientific reason why you can’t stop watching them.

It is amazing how we have the ability to see series, chapter after chapter, without realising the time we are investing in it.

We all have lived the following situation: you start to see a series in the middle of a the day and suddenly, when you take your eyes off the screen, it’s already gone dark, and you’ve finished another season of Friends. How that happens has a scientific explanation. So from now on, you can justify why you are a coach potato.

There are some characteristics that make us being constantly attracted to our screen. Here we have some:

Visual bursts: We are biologically designed to pay attention to fast movements, which is known as reflex oriented. This phenomenon is activated when a scene changes quickly from one picture to another (for example in a fight). We become more involved with what happens, to the point that it is physically difficult to see the other way.

The control of your eyes. The more control a director gets over a scene, the more addictive and potentially difficult to avoid seeing it gets. This is about empathy. The director puts on the skin of the audience, and decides what the viewers will be more attracted to.

The position of every single thing is very important. This includes the actors and even the hole props.

Our eyes need to see a continued action scene, but what is more important, it is that they feel comfortable.

The affection:

When you spend lot of time with someone, you start taking care about that person or worrying about him. The same happens with the characters, when you have seen some seasons of any series it is pretty impossible to not having affection for some of them. Actually, you feel that you really love them, and sometimes that becomes being an obsession.

The point here is that when you have an attachment with someone, is normal to desire continue watching that character, and as a consequence that series.
