Response time or processing speed is a common measure in psychological research experiments. Clinically, processing speed is a measure of how quickly information is processed to achieve a desired behavior. In clinical populations, processing speed can be impacted when lesions, atrophy, and other forms of brain damage occur within cortical and subcortical regions of the brain. This can cause people to feel frustrated and act hastily in a way that is unfavorable to their safety. Working on this skill is vital to help your client be able to make quick, accurate, and precise decisions that can benefit them long-term.
