; Standardized
neuropsychological tests : These tasks have been designed so the performance on the task can be linked to specific
neurocognitive processes. These tests are typically
standardized, meaning that they have been administered to a specific group (or groups) of individuals before being used in individual clinical cases. The data resulting from standardization are known as normative data. After these data have been collected and analyzed, they are used as the comparative standard against which individual performances can be compared. Examples of neuropsychological tests include: the Wechsler Memory Scale (WMS), the
Wechsler Adult Intelligence Scale (WAIS), Boston Naming Test, the
Wisconsin Card Sorting Test, the
Benton Visual Retention Test, and the Controlled Oral Word Association. ; Brain scans : The use of
brain scans to investigate the structure or function of the brain is common, either as simply a way of better assessing brain injury with high resolution pictures, or by examining the relative activations of different brain areas. Such technologies may include
fMRI (functional magnetic resonance imaging) and
positron emission tomography (PET), which yields data related to functioning, as well as
MRI (magnetic resonance imaging) and
computed axial tomography (CAT or CT), which yields structural data. ; Global Brain Project : Brain models based on mouse and monkey have been developed based on theoretical neuroscience involving working memory and attention, while mapping brain activity based on time constants validated by measurements of neuronal activity in various layers of the brain. These methods also map to decision states of behavior in simple tasks that involve binary outcomes. ;
Electrophysiology : The use of electrophysiological measures designed to measure the activation of the brain by measuring the electrical or magnetic field produced by the nervous system. This may include
electroencephalography (EEG) or
magneto-encephalography (MEG). ; Experimental tasks : The use of designed experimental tasks, often controlled by computer and typically measuring reaction time and accuracy on a particular tasks thought to be related to a specific
neurocognitive process. An example of this is the
Cambridge Neuropsychological Test Automated Battery (CANTAB) or CNS Vital Signs (CNSVS). ==See also==
