I need to find more information about these. There were apparently studies published in 2010 on experiential orientation vs. material orientation by Leaf Van Boven and collegues. I think it is this paper:
Van Boven, L., & Campbell, M., & Gilovich, T. (2010). Stigmatizing materialism: On stereotypes and impressions of materialistic versus experiential pursuits. Personality and Social Psychology Bulletin, 36, 551-563.
