One rule of thumb is to consider any difference amount occurring less than 5% of the time becomes a possible “clinically significant” difference in the profile and should be noted in any report of test results. In addition to this data of “frequency of differences,” the user should note whether or not the differences in pairs of scores are statistically significant (See Table H.1 in Manual). *Indicates significance. Interpretative Results: Donald is a bright young man, whose nonverbal IQ falls within the Average to Above Average range. He performs best on tasks which require nonverbal reasoning abilities which focus specifically on rule generation related to problems of seriation or sequential information (SO Scaled Score= 15). Donald does well on tasks of basic visual interference, and can easily avoid distractions while searching for specific information (FG Scaled Score = 13). On tasks which require organization and the ability to use deductive reasoning, Donald also did well (FC Scaled Score = 12). Donald also demonstrated abilities to generate rules out of partial information, and inductively hypothesize what piece would complete a whole pattern (CA Scaled Score = 11). Overall, Donald showed no weaknesses in his nonverbal abilities measures by the Leiter-3. On the Attention/Memory Battery, Donald did have significant differences between his nonverbal IQ and his nonverbal memory, as well as between his nonverbal IQ and his processing speed. However, both his nonverbal memory and his processing speed abilities fall within the average range (NV Memory = 97; Processing Speed = 100). Oddly, Donald performed better on a task of reverse memory, than he did on forward memory. This type of pattern suggests that memory span or attentiveness are in question. His performance on the Reverse Memory Subtest indicates he has the complex mental ability requiring him to store and juggle information using mental effort that requires good working memory (RM Scaled Score = 11). On Forward Memory, Donald struggled slightly with memory span, which is required on this subtest (FM Scaled Score = 8). His slightly below average performance on this subtest, especially when compared with his other scores, indicates this is an area of weakness for Donald. Donald’s Processing Speed was also composed of differing scores. He did well on tasks which require sustained attention, visual prolonged attention, visual scanning, and motoric inhibition (AS Scaled Score = 12). The score that best discriminates individuals diagnosed with ADHD from individuals without attentional deficits is the errors score on the Attention Sustained Subtest. Donald had zero errors, thus indicating no signs of ADHD. Donald’s relative struggle in Processing Speed occurred on the Nonverbal Stroop Incongruent Correct task (NSic Scaled Score = 8). He was much slower at this task, which impacted his score. He may not have been able to hold the incongruent image in his mind long enough to scan the possible answers, should he actually have struggles with his memory span. However, a more logical reason for this discrepancy, considering Donald performed well throughout the nonverbal IQ tasks, is that he was somewhat anxious about the task, and so he slowed his performance, and did not accomplish as many (Anxiety Scaled Score on Examiner’s Rating Scale = 6). Overall, Donald is functioning in the Above Average range of general intelligence, but experiences some weaknesses in Nonverbal Memory and Processing Speed. His scores on the Examiner Rating Scale indicated he struggled with symptoms of anxiety and also organization and impulse control, which appear to have affected his performance on this assessment. This should be considered in his everyday life as well, as these symptoms may interfere with his ability to engage in daily activities.
