You don't need to know the words' definitions, only recognize them as real or non-real. One real word I didn't recognize was "ducker" - I thought it was only a name (and even the meaning "a person who ducks" didn't occur to me)!
At the end of the test it gave this link to another study/word association test which I haven't tried yet: https://smallworldofwords.org/en
