Studies of Assessment

Study Results on Driver Assessments
Numerous studies have demonstrated that poor performance measured by Posit Science visual training technology can reliably predict an individual's risk of driving unsafely and his or her risk of being involved in a car crash. Key results include:

• Individuals who perform poorly on the Posit Science technology are almost twice as likely to be involved in a traffic accident as those who perform well.
• Drivers who perform poorly on the Posit Science technology take longer to cross intersections and start to cross later, leaving a much smaller space cushion for oncoming vehicles.
• Performance measured by Posit Science technology is a better indicator of crash risk than any other visual, cognitive, or motor skills test.

Study Results on Mobility Assessments
Helping older adults preserve their mobility is key to ensuring they can live safely and independently. Falling, stumbling, and other mobility issues not only pose a risk to the health of older adults, but they can also seriously impact quality of life. Posit Science technology has been clinically proven to reliably predict falls, difficulty with walking, and other types of mobility issues.

Key results on this training include:

• Poor performance on the Posit Science program predicts poor performance on 16 directly observed mobility assessments, such as walking along a designated path and rising from a seated position to a standing position.
• Poor performance on the Posit Science program predicts more collisions with obstacles while walking.
• Poor performance on the Posit Science program is associated with a higher number of falls and a greater number of falls that result in injury.
• Visual speed and attention are crucial for safe mobility and fall prevention.
