The visuospatial sketchpad is the part of our working memory that handles visual and spatial information. The sketchpad kind of works like RAM in computers, storing information temporarily for our minds to change and store the information in our heads. Imagine giving directions or knowing how to turn a Rubik’s cube, all inside your head.
Additionally, it lets us recreate images we’ve seen in the past (from memory) or in real-time.
Imagine you are drawing a picture of your ex-girlfriend. Initially, you start from a happy picture of when you were both together. But as the drawing progresses, you keep having to look back at the picture to remember what she looks like. Unfortunately, the utter pain of existence without her also keeps creeping in, and you are unable to finish the picture. But the act of remembering what she looks like is an example of the visuospatial sketchpad. Yay!
