6 Item	63.50 ± 5.4	34.30 ± 4.1	47.06 ± 5.	50.39 ± 6.9	38.14^# ±7.6	38.59 ± 5.2	33.83 ± 6.3	38.20 ± 3.6

The mean (±SEM) for the total interaction time seen with stimuli is recorded for each sample and test phase in the IST and DST with objects or odors. * Significant main effect of Phase on object IST and DST (p < 0.05). # Significant effect of Item Count on exploration times in the sample phase of the odor IST (p = 0.047).
