  1. Neuropsychological Testing

  2. Purposes of Neuropsych Testing • Determination of brain damage • Localization of brain lesions • Determination of functional consequences of brain injury • (Educational testing)

  3. Some Conditions That Cause Neurological Damage • Head trauma • Vascular disorders • Degenerative disorders • Toxic conditions • Infections • Neoplasms • Anoxia

  4. Common Cognitive Functions Assessed • Attention • Memory • Visual-spatial abilities • Psychomotor speed • Planning/sequencing • Abstract reasoning • Language (expressive and receptive) • Cognitive flexibility • Lateral differences

  5. Approaches to Neuropsych Testing • Standardized batteries • Luria-Nebraska Neuropsychological Battery • Halstead-Reitan Battery • Individualized batteries • Often includes an IQ test • Specific tests

  6. Luria-Nebraska Neuropsychogical Battery • Allows for testing of limits • Emphasis on optimal performance • 279 items, across 12 scales • Produces a coded profile, which is then interpreted • Item analysis within scales

  7. Halstead-Reitan Battery • A longer test, more standardized • Halstead category test • Tactual test • Rhythm test • Speech-sounds perception test • Finger oscillation test • (Trail-making test) • (WAIS and MMPI)

  8. Bender Visual Motor Gestalt Test(Bender Gestalt) • An older test, frequently used by psychologists who are not neuropsychologists • Serves as a projective as well • Errors include: perseveration rotation distortion of shape failure of integration

  9. Wechsler Memory Scale • Assesses several kinds of memory fairly quickly • Subtests: Information and orientation Mental control Figural memory Logical memory Visual paired associates Verbal paired associates Visual reproduction Digit span
