Hi,

Is it right to speak of the decrease or increase in performance? Can I say, for instance:

"Mental calculations caused the decrease of driving performance."?

Thanks!
 
    • You can say: "Mental calculations caused a decrease in driving performance." Although I don't know what that would mean.

    Yes, but only if you change "of" to "in", as Copyright said, and have previously referred to the decrease in driving performance (hence the use of "the"). Of course, you should also have demonstrated the truth of the statement. :)
