The Repeated Word

What do we direct our attention to when reading text? Can you find a mistake in the text on the sign?

It is the task of a proof-reader to discover mistakes such as the repetition of a word in the text, as shown above. Most of us don’t deliberately look for mistakes. Instead, we concentrate on the message of the text. In a text that is very familiar, such as something you have written yourself, it is almost impossible to notice mistakes that.

The mistake in the sign here may be particularly difficult to spot, since it occurs at the end of one line/beginning of the next.
