Abstract This study investigated the effects of displaced objects and spatial reorganization on habituation of exploratory behavior. The subjects‚ rats‚ each individually spent 5 minutes in an open field for 6 trials. Throughout the study‚ exploratory behavior was measured in the number of contacts the subject made‚ the number of ambulations‚ and contact time (seconds). Trials 1-5 were mainly used to familiarize the subject with its surroundings‚ naturally leading to decreasing amounts of exploratory

subjects were used in order to look for significant metabolic changes when the test subjects were exposed to different drugs and physiological changes. In this test‚ three different rats were used to see the different metabolic rates when exposed to different drugs and hormones on a normal‚ healthy rat‚ a rat with no thyroid‚ and a rat with no hypophysis. The significance of this experiment is to show the difference in metabolism and metabolic rate in healthy individuals‚ subjects‚ and individuals
