Table 2. Changes in the time spent and distance travelled between Empty Zone 1 and Holding Zone 1 and between Empty Zone 2 and Holding Zone 2 in both the control and stressed groups during the social novelty preference test.

Groups	Parameters	Social Chamber			Novelty Chamber
		EZ1	HZ1	*P-value	EZ2	HZ2	*P-value
Control (n=7)	Time Spent	15.057	83.914	0.003	23.743	139.271	0.004
	Distance Travelled	1.145	4.99	0.009	1.67	7.069	0.018
Stress (n=7)	Time Spent	24.757	59.829	0.005	29.843	132.371	<0.001
	Distance Travelled	1.123	2.948	0.001	1.876	5.761	<0.001

Both the control and stressed groups spent more time and travelled a longer distances in Holding Zones (HZ1, HZ2) than Empty Zones (EZ1, EZ2). *P<0.05 is significant. The two-tails t-test was performed with the assumption of unequal variances. Abbreviations. EZ, Empty Zone; HZ, Holding Zone; n, number of samples.
