Evidence reveals that visual processing speed decreases with age. The Motor-Free Visual Perception Test- Third Edition (MVPT-3) has an age-normed Response Time Index that measures visual processing speed. In 2015, a new version, Motor-Free Visual Perception Test- Fourth Edition (MVPT-4), was published. The new MVPT-4 does not yet demonstrate its utility in measuring visual processing speed. The purpose of this study was to explore if differences in visual processing speed between younger adults ages 20-35 years and older adults ages 70 years and older could be detected using the new MVPT-4. Results revealed a significant difference between older and younger adults’ time to complete the MVPT-4 (p <.05). This pilot study demonstrated that the MVPT-4 may be able to detect age-related changes in visual processing speed and therefore, a possible clinical tool for occupational therapists.
