From my experience, this is true, but reward is not why such behavior becomes culture. Culture is ingrained by leaders who act and lead according to value organization adheres to. The key here is to have leaders at every level who embodies such value. Having such values baked into performance evaluation is how "reward" plays a role in engendering and sustaining such culture. It is about whom does the organization promotes and chooses to be a leader. It's not about simple salary increase or cash rewards, as such things don't last more than a few months.
