The 4AT has 4 parameters: Alertness; Abbreviated mental test-4 (AMT4) Attention (months backwards test) Acute change or fluctuating course; The score range is 0–12, with scores of 4 or more suggesting possible delirium. Scores of 1-3 suggest possible cognitive impairment. There are several indications of a positive score of 4 or more.
The Herrmann brain dominance instrument (HBDI) is a system to measure and describe thinking preferences in people, developed by William "Ned" Herrmann while leading management education at General Electric's Crotonville facility.
The Abbreviated Mental Test score (AMTS) is a 10-point test for rapidly assessing elderly patients for the possibility of dementia. It was first used in 1972, [ 1 ] [ 2 ] and is now sometimes also used to assess for mental confusion (including delirium ) and other cognitive impairments .
Graph showing a typical Auditory Brainstem Response. The auditory brainstem response (ABR), also called brainstem evoked response audiometry (BERA) or brainstem auditory evoked potentials (BAEPs) or brainstem auditory evoked responses (BAERs) [1] [2] is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp.
This number is known as the Corsi Span, and averages about 5 for normal human subjects. An fMRI study involving subjects undergoing this test revealed that while the sequence length increases, general brain activity remains the same. [19] So while humans may show encoding difficulty, this is
Each model is available in three performance levels (1, 2 or 3) which offer a different level of sound processing. Rechargeable versions come with either a desktop charger or a portable SmartCharger.
Neuropsychological tests are designed to assess behaviors that are linked to brain structure and function. An examiner, following strict pre-set procedures, administers the test to a single person in a quiet room largely free of distractions. [1] An example of a widely-used neuropsychological test is the Stroop test.
A popular multi-dimensional instrument for the measure of cognitive style is the Myers–Briggs Type Indicator.. Riding (1991) developed a two-dimensional cognitive style instrument, his Cognitive Style Analysis (CSA), which is a compiled computer-presented test that measures individuals' position on two orthogonal dimensions – Wholist-Analytic (W-A) and Verbal-Imagery (V-I).
