What is a Klang Association in psychology?

?Klang association is a topic which has become crucial for some
on-going world-class leading-edge discussions of linguistic relativity
today.?

My guess is most people haven't found this because it is more commonly
spelled "clang" although I think "klang" is technically acceptable as
well.  Try googling that if you want more information.  Clang
associations are when someone speaks words that are connected by sound
instead of by meaning, essentially speaking gibberish.  It is
generally associated with schizophernia or sometime bipolar disorder
and is evidence of disordered thinking.  Here's an example of a "clang
association."

"I want to say the play of the day, ray, stay, may I pay"
