For the first three items, 1 point is given for correctly reading it out loud and 1 point is given for correctly performing the command. If the client fails to perform the command well, the examiner imitates the action; 2 points are given for a good performance at this point; 1 point is given for an approximate performance at this point. The client must read 10 words, with irregular spelling, from the stimulus book, out loud. The client must point to what the examiner says. One point is given for each correct answer. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. There were excellent correlations between the K-BNT score and K-WAB Object Naming (r=0.720) and Word Fluency (r=0.613) tasks and Naming subtotal score (r=0.719). It is most often the result of stroke or head injury.

It is most often the result of stroke or head injury.An individual with aphasia may experience difficulty expressing themselves when speaking, difficulty understanding the speech of others, and difficulty reading and writing. There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation. Videotapes were viewed and scored by 3 judges. Published in English (Risser & Spreen, 1984). Inter-rater reliability determines the extent to which two or more raters obtain the same result when using the same instrument to measure a concept.
