How do intelligent hauntings react to a changing environment over time?

While talking this week with a friend who is no stranger to paranormal activity, she brought up an excellent question that I had never considered. As we were talking about residential hauntings she asked "How do you think spirits react to things we have now that they didn't have when they were living?" My only answer was "I've never thought about it before but that is an excellent question!"

How do you think human spirits in the case of an intelligent haunting react to new technology that didn't exist when they were alive? Imagine if you lived(and died) during the 19th century. Would you comprehend the modern things in your surroundings that we take for granted? A prime example of this question that she mentioned is if they understand what a television is. Think of all of the things that wouldn't have existed if you were alive during that time. Your TV, phones, computers, air conditioning, cars, microwave, medical devices, etc... the list could go on continuously of things that could possibly seem foreign or outright alien under those circumstances if you didn't understand the technology. 

So with this seed of thought planted, what do you think?
