What Are Three Components Of Attitude?

The definition of attitude is; 1)Posture- which to me would mean the way you carry your body movements or how you display your body language, right?
2.) mental position or feeling with regard to a fact or state- Here I would think that this is in reference to how you mentally feel about a fact or the state of mind that your in.
3.)a cocky arrogant manner- This to me would mean how you view who you your self are.
