The use of touch-screen based technology in lab testing is a long established method. Focusing on two areas, evidence was collected validating the creation of a standardized assay for touch-screen vision testing. Previous research has shown that learning method is important for a good assay. A massed learning method was compared to a spaced learning method to determine which would best benefit the Acuisee-vR. A second goal was to replicate the finding that albino rat’s vision is significantly worse than pigmented rats. 24 rats, 16 male Lister Hooded rats and 8 Long Evans albinos, were used in this study. A series of basic visual acuity tests involving stimulus control were conducted to determine two things; which learning type should be used, and can the Acuisee-vR replicate a known finding regarding rat vision. Testing used a basic conditioning and reward system along with food deprivation to motivate the rats to complete the decision making task. Results showed that the massed learning group was the better learning method to use, although it was determined that after a few weeks it is no longer massed learning as traditionally understood. The results also showed that albino rats performed significantly worse than the pigmented rats, supporting previous research and validating the Acuisee-vR as a useful assay for touch-screen vision testing. Conclusively this study helped to validate the Acuisee-vR as a useful tool for vision testing in rats, and to further its development into a finished product. Future study ideas and potential changes to the Acuisee-vR, are discussed based on these findings.
