Attitudinally is formed from "attitude" (from Latin "aptitudo", meaning disposition or state of being) and "-ally" (meaning in a manner relating to). The word describes something done in a manner that relates to one's disposition or state of mind.
Think of 'attitude' as your state of mind and '-ally' meaning in a manner. So, attitudinally means doing something in a way that reflects your state of mind.
