TEA
"The TEA gives a broad-based measure of three important clinical and theoretical aspects of attention: selective attention, sustained attention and attentional switching. The TEA has three parallel versions, is ecologically plausible and acceptable to patients. It is sensitive enough also to show normal age effects in the normal population. It can be used analytically to identify different patterns of attentional breakdown. The TEA has a wide range of applications, from patients with Alzheimer's disease to young normal subjects." -- Company website.
