affect or has an effect

[Attila]

Hi All,

I usually use the sentence This doesn't affect you

but I don't know whether I could use following instead: This doesn't has an effect on you

I heard that if I talk about a person I'd use affect and if it is about a thing I should use has an effect.

Is that right?

Hi,

[Attila]

Thanks,

[Prezbucky]

Isn't "affect" also occasionally used as a noun as part of (for instance) a description of psychological symptoms?

--> Mike exhibits a moribund affect when faced with difficult choices.

Is that right?

Hi,

Yes, I'm sure you're right but I didn't want to get too technical.
