neophilia

en-noun

neophilia (usually uncountable, plural neophilias)

Coordinate term: paleophobia

In order to account for the appearance of a novelty response in the deficient or recovered rat, Rozin and Rodgers (1967) suggest that either the state of deficiency triggers an innate neophilia, or that the deficient rat develops an aversion to the deficient diet and thus shows a strong preference for any new food. […] The neophilia of thiamine-deficient rats could be a direct consequence of a specific aversion for familiar deficient diet (paleophobia). On the other hand, it is also possible that a true neophilia exists along with the paleophobia.

1967, Paul Rozin, “Specific aversions as a component of specific hungers”, in Journal of Comparative and Physiological Psychology, volume 64, number 2, →DOI, page 237; 242:
