2 NEUROPSYCHOLOGICAL EXAMINATION A method of examining the brain; abnormal behavior is linked to the fxing of specific areas of the brain through the use of the psychological test neurological dysfunction is reflected in test performance

3 REFERRAL QUESTIONS You might be referred for a neuropsychological evaluation to: 1. find possible problems with your brain functioning, 2. form a diagnosis, 3. define your thinking skill strengths and weaknesses, 4. guide treatment for your personal, educational or vocational needs, 5. make relevant recommendations to your health care provider(s), and/or 6. document possible changes in your functioning over time.

4 WHAT IS A NEUROPSYCHOLOGICAL EVALUATION Attention Memory Reasoning and Problem-Solving Visual-Spatial Functions Motor Functions Academic Skills Emotional Functioning Intellectual Functioning

5 PSYCHOMETRIC ASSESSMENT Standardization Reliability Validity

6 STANDARDIZATION Procedures are completely specified for: Administration Scoring Interpretation Provides normative group

7 RELIABILITY Consistency or Accuracy X = T + E X = score obtained by individual T = true or actual amount of attribute that individual possesses E = amount of random error present at time of testing The less reliable the test the more it reflects error (error: ambiguous items, inconsistent instructions, etc)

8 RELIABILITY Equivalent Forms Test-Retest Split-Half Internal Consistency Reliability: 0 to

9 VALIDITY Content Validity Is the test an adequate sample of the knowledge that it purports to measure? Criterion-Referenced Validity How well does the test predict performance? Construct Validity Provides information about the trait or attribute possessed by the individual.

10 ATTENTION Based on Sohlberg and Mateer s clinical model of attention Focused attention Sustained attention Selective attention Alternating attention Divided attention

11 ATTENTION PROCESS TRAINING Based on Sohlberg and Mateer s clinical model of attention Focused attention The ability to focus on specific sensory information Sustained attention Selective attention Alternating attention Divided attention

12 ATTENTION PROCESS TRAINING Based on Sohlberg and Mateer s clinical model of attention Focused attention Sustained attention Vigilance, persistence, mental control, working memory Selective attention Alternating attention Divided attention

13 ATTENTION PROCESS TRAINING Based on Sohlberg and Mateer s clinical model of attention Focused attention Sustained attention Selective attention Maintain behavioral set in the presence of distractors Alternating attention Divided attention

14 ATTENTION PROCESS TRAINING Based on Sohlberg and Mateer s clinical model of attention Focused attention Sustained attention Selective attention Alternating attention Shift one s focus of attention Divided attention

15 ATTENTION PROCESS TRAINING Based on Sohlberg and Mateer s clinical model of attention Focused attention Sustained attention Selective attention Alternating attention Divided attention Simultaneously respond to two or more stimuli
