Discrepancy Analysis Impeachment

Page 70:

The interpretation of the difference between a single sub-test score and the individual’s own mean score is an intraindividual comparison. Strengths and weaknesses identified in this way are strengths and weaknesses relative to the individuals own general ability level. Therefore , a sub-test of scaled score that is high in absolute value,that is well above 10, may still represent a relative weakness for an individual of extremely high general ability; on the other hand, a fairly low scaled score may indicate a relative strength of an individual of generally limited ability.

Because of the relatively high intercorrelations between intellectual functioning and memory, the examinees IQ scores become an index or estimate of his or her probable level of memory ability. Discrepancies between the estimated memory performance based on IQ scores and the examinees actual memory performance form the basis for the discrepancy analysis. The discrepancy score then provides a global indication of whether or not the examinees ability to learn and remember new material is commensurate with what would be expected on the basis of his of (sic) her intellectual functioning.

Page 212:

To the extent that an examinee’s overall intellectual functioning has remained relatively stable, a large discrepancy score in which the IQ score is greater than the memory score suggests a more focal memory impairment or weakness in the context of relatively intact overall abilities.

Understanding Subtle Brain Injury

The concussions that disable, are almost always more symptomatic at 24 hours, than at the 2-4 hour time frame when injured persons are evaluated in the emergency room. Brain injury symptoms escalate over the first 24 hours, because brain injury involves a cascade of events. It is critical that if you are still symptomatic the day after your injury, go back to the same Emergency Room, don’t wait for a doctors appointment. It is critical that the Emergency Room personnel see that the symptoms still persist or have gotten worse.
