Autistic Perception: the Magnifying Glass Example

This article explains in a clear and practical way autistic perception: how people with autism and Asperger’s perceive the world.

Imagine reading a book having to use a magnifying glass. If the magnifying power of the lens is low one full sentence at a time can be read (image 1). You can easily focus to the meaning of the sentence as a whole, and you can easily predict what comes next. In the example of image 1, the sentence “You can go hunting with a knife and” can easily be completed with “catch a bear” [1]. This is how a person not on the autistic spectrum perceives the world.

 

Now imagine having to read using a stronger magnifying glass: this time you can only read a couple of words at once (image 2). You start reading from the beginning of the sentence, a few words at a time, until you reach “a knife and”. At this point, your mind, focused on the few words it is seeing, will be tempted to predict the next ones as “a fork”. The full sentence, “You can go hunting with a knife and a fork” doesn’t make much sense; however, if you take into account you could only see “a knife and”, the “a fork” completion looks more correct than “catch a bear”. This is how a high-functional autistic person (or an Asperger) perceives the world.

 

Lastly, please imagine having to read using a very strong magnifying glass, whose “zoom” effect is so strong it will only allow you to see a few letters at a time (image 3). You are not able anymore to make use of the meaning of the full sentence: you are now unable to predict which words follow the “and” without using the context provided by the previous ones (which you cannot see anymore). Instead, the letters are now much more detailed to you, and other thoughts start to occupy your mind (for example, the font used to print the letters). This is how a low-functional autistic person perceives the world.
