A perceptual maze test sensitive to brain damage

A Perceptual Maze Test Sensitive to Brain Damage.

A preliminary report on a perceptual maze test sensitive to brain damage.

During an investigation into the clinical effects of prefrontal leucotomy, an attempt was made to design a simple psychological test procedure sensitive to organic damage to the frontal lobes. The preliminary results obtained with the perceptual maze test reported below suggest that it is sensitive both to cerebral damage in the frontal regions and to damage to the anterior temporal lobe. Becau...

Perceptual Organization Test (POT) for the Differentiation Between Schizophrenia and Brain Damage

The Perceptual Organization Test (POT) has been designed for the purpose of measuring impairment in cognitive functioning as reflected in a purely perceptual task. Such a test is badly needed in view of the fact that the most widely used tests of perception are not really pure tests of perception. Bender Gestalt (Bender, 1960), for example, requires a certain measure of motor skill in copying n...

What is the Most Sensitive Measure of Water Maze Probe Test Performance?

The water maze is commonly used to assay spatial cognition, or, more generally, learning and memory in experimental rodent models. In the water maze, mice or rats are trained to navigate to a platform located below the water's surface. Spatial learning is then typically assessed in a probe test, where the platform is removed from the pool and the mouse or rat is allowed to search for it. Perfor...

A computerized test battery sensitive to mild and severe brain injury.

OBJECTIVE Computerized neurocognitive testing (CNT) appears to be suited to measure relatively mild degrees of neurocognitive impairment in circumstances where speed, efficiency, and low cost are important. Computerized tests are used in the evaluation and management of patients who have had mild brain injuries; the objective is to determine if computerized testing is equally reliable and valid...
