allocentric

The adjective is derived from allo- (prefix meaning ‘different; other’) +‎ -centric (suffix meaning ‘having a specified object at the centre, or as the focus of attention’). Sense 3 (‘of a tourist: tending to be adventurous’) was coined by the American travel researcher Stanley C. Plog in a paper presented to the Southern California Chapter of the Travel Research Association on 10 October 1972, which was later published in February 1974.

The noun is probably derived from the adjective.
