Insignificant influence of test order on cognitive behavior in Wistar ratsYow Hui-Yin, Nurulumi Ahmad, Norazrina Azmi, Mohd Makmor-Bakry.
Objectives: The aim was to evaluate the effects of test order in behavioral performance of Wistar rats in cognitive performance tasks. Materials and Methods: The rats were tested with both object recognition and object location tasks in different test orders with an inter-test interval of 1-day. Results: An open field box sized 60 × 60 × 40 cm was associated with better experimental outcome compared with box sized 100 × 100 × 50 cm. Test order has insignificant effects on the exploration activity of rats with the 1-day inter-test interval. Conclusion: Test order of the cognitive performance tasks with inter-test interval of 1-day did not influence the performance of Wistar rats.
