How to keep text messages on my iphone from showing on my MacBook?

I just bought a MacBook Air. I already have an iPhone. I want my phone and laptop to "communicate" via iCloud (?). I. E. I want my photos, songs, videos, to sync from my phone to my PC however, I DO NOT want my text messages to show up on the PC (which they are currently doing). How do I change this feature?

For the record, those are iMessages not text messages. Check the iCloud settings in the System Preferences.
