In addition to using this app in the traditional sense, I like to print out screenshots to make a paper-pencil scanning task. Practice mode only allows left to right scanning.Test mode allows targets to be tapped in any order, indicating if there is a particular area that is being neglected when scanning.Can choose similar or dissimilar targets and can choose one or two targets.Ten levels provide a seemingly never-ending variety of scanning tasks.Especially helpful for those with a visual neglect. Can program the app to have a line on either the left or right side to encourage scanning all the way to the edge.Number of lines is customizable, allowing 24-228 targets per screen. Results can be emailed, which makes for quick and easy data collection and progress monitoring.Visual attention impairments in Alzheimer’s disease. Berlin, Heidelberg: Springer Berlin Heidelberg.

Investigative Ophthalmology & Visual Science, 34(11), 3110-3123. Visual attention problems as a predictor of vehicle crashes in older drivers. If you want to learn more about this topic, we invite you to watch the following video about visual attention and how it relates to memory loss. Instead, a cognitive test of visual attention serves as a true indicator of functional decline. Vision tests aren’t enough to determine someone’s ability to walk, drive, or perform other mobility tasks. In fact, older drivers with poor attentional capacity due to a limited visuospatial field are six times more likely to crash compared to those with no or minimal impairment. Falling or lower levels of mobility in seniors are strong indicators of reduced visual attention, and may indicate the need for long-term care.Ĭontrary to common misconception, poor vision isn’t the primary cause of motor vehicle accidents among seniors. Poor visual attention lowers the ability to avoid obstacles while walking. When these abilities decline, the visual field becomes smaller, hindering performance in everyday tasks that require visual search, such as reading, driving a car, identifying someone in a group, or finding your favorite breakfast bar in the cereal aisle. The deterioration of visual attention abilities is common with dementia, and is usually the first indicator of cognitive impairment following memory loss. This sort of focus allows us to perform everyday tasks, such as walking and driving, without injuring ourselves. Seeing is a complex process that allows us to efficiently deal with massive amounts of external information by selecting relevant information and filtering out irrelevant information.Īs we observe the environment around us, that information is stored in our working memory, so that we are aware of potential hazards around us. What do you see? A swimming pool? The dog chasing a squirrel? Whatever it is – whatever object, color, or movement you zoom in on – results from the proper operation of your visual attention.Īfter all, seeing is more than our eyes’ ability to view external stimuli. You’re in the kitchen, standing at the stove, looking out the window into the backyard.
