Yes, for the most part. This typically doesn't matter in the limit games, but can in the NL games if you are playing high enough. A few things to remember are:

-Don't look at your cards until it is your turn to act preflop
-Take the same amount of time each time you bet/raise (but don't take too long and hollywood it up)
-Speak clearly when declaring a raise, bet, or all-in

Act natural. Talk to the players if you like to talk and be social, or just look down at the felt if you are afraid of giving off a tell. Whatever is most comfortable and repeatable in all situations is what I suggest you do.

Good luck!
