Studied the conditions under which neophobia and enhanced neophobia occur in the albino rat in 5 experiments with a total of 160 male albino rats. Neophobia to a .1% saccharin solution was demonstrated in a 10-min single-bottle test. This neophobia was enhanced by pairing water ingestion with a radiation exposure of 100 r or an injection of LiCl 24 hrs prior to the saccharin test. In addition, it was found that the differences in consumption of saccharin in a 10-min single-bottle test due to neophobia and enhanced neophobia were produced by consistent differences in drinking rates which appeared early in the 10-min period. The disappearance of neophobia and enhanced neophobia in a 1-hr single-bottle test suggested that the effects of neophobia and enhanced neophobia are short-lived and are best measured in a brief single-bottle test. Enhanced neophobia was not found when 2 days of water drinking were interposed between LiCl poisoning and saccharin testing. (22 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
