to measure the fluid intelligence in neurological patients. This test is unique in that it offers more accuracy than any other test available for this type of measurement. VESPAR is divided into six sections. There are three matched sets of verbal and spatial reasoning problems, where each is dedicated to one of three forms of inductive reasoning. This includes odd one out, by analogy, and series completion. VESPAR is able to overcome many restraints that arise when performing more conventional reasoning tests by using stimuli that is more readily accessed by patients with physical or cognitive impairments due to neurological illness. VESPAR does not use timing to help evaluate performance, instead it uses high frequency stimulus words or visually distinct spatial stimuli to help determine its results. VESPAR has a multiple choice format. This format has been adopted to reduce both short-term memory load and output demands on the patient. The assessment of patients for neurodiagnostic and neurorehabilitation needs will be facilitated. VESPAR only requires the patient to do simple pointing gestures. The spatial section of the test measures the fluid intelligence of patients with

side of the brain. Although the tests were originally devised to investigate theoretical issues, they have excellent selectivity and sensitivity in a clinical context leading to their wide adoption. The VOSP tests were designed to place limited demands on other cognitive abilities and are generally easy for people without brain disorders. Some VOSP tests have been incorporated into other test batteries (e.g., The
Rookwood Driving Battery) and they have also influenced other screening measures (e.g., The ACE-R). There are eight untimed tests in the VOSP that can be given either separately or as a whole. The scores obtained in a testing session can be compared with those obtained by people with brain injuries and with controls. The VOSP is widely used by clinical and research psychologists and has featured in over 250 research publications. The VOSP can be purchased from Pearson for around the price of US$ 230.00.

269:. The verbal section does the same for patients with visual and spatial problems. VESPAR focuses more the instinctive ability of a patient, rather than educational experience. Thus, although originally developed for adult neurological populations, the test is suitable for a wide range of clinical, educational, occupational, and research applications. This test is also available for purchase at most online bookstores.

Throughout her career, Warrington conducted many ground breaking experiments and developed many cognitive functioning tests to measure a patient's cognitive abilities. Warrington's work is often credited with helping shape the basis of modern-day cognitive psychology. Many of
Warrington's tests are

To further validate the discovery of "normal" memory in severe amnesics, Warrington used methods involving stem completion. The stem completion tasks involved patients learning a battery of words, and later identifying the learned words. Patients were able to identify a previously learned word when

Another test that is still in use is the Verbal and
Spatial Reasoning Test also known as VESPAR. VESPAR is a test that was designed by Warrington and Dawn W. Langdon in 1996. VESPAR is a reasoning test that presents a fairly new approach in how reasoning tests are performed. This test is designed

British development of Cognitive Neuropsychology a research approach that has had implications beyond the clinical sphere, providing important insights into the way that the normal human brain perceives, remembers, and talk about words, objects and events.
