TOVA, which stands for Test of Variables of Attention, is a computer-based test designed to assess attention and impulsivity in individuals. It was developed by researchers at the University of California, San Diego and is commonly used in clinical settings and research studies.The TOVA measures specific aspects of attention, such as sustained attention (the ability to maintain focus over time), variability of attention (the consistency of performance), response time (the speed at which one responds to stimuli), and impulsivity (the tendency to respond recklessly or without thinking). It can be used to assess attention deficits associated with various conditions, including attention-deficit/hyperactivity disorder (ADHD) and traumatic brain injury.During the TOVA test, individuals are presented with a series of visual stimuli on a computer screen and are asked to respond quickly and accurately to specific targets while ignoring distracting non-targets. The test takes approximately 21 minutes to complete.The results of the TOVA test provide objective measurements of an individual's attentional abilities and can help clinicians or researchers assess the severity of attention deficits, track changes in attention over time, evaluate treatment effectiveness, and aid in diagnostic decision-making.It's important to note that the TOVA is just one tool used in assessing attentional abilities. A comprehensive evaluation typically involves multiple measures, including subjective reports from individuals or their caregivers, behavioral observations, and additional neuropsychological tests.

TOVA's main products are cosmetics and skincare products.
