The Staggered Spondaic Word Test. A ten-minute look at the central nervous system through the ears.
We have described three major groupings that encompass most auditory processing difficulties. While the problems may be superimposed upon one another in any individual client, each diagnostic sign is closely associated with particular communication and learning disorders. In addition, these behaviors may be related back to the functional anatomy of the regions that are implicated by the SSW test. The auditory-decoding group is deficient in rapid analysis of speech. The vagueness of speech sound knowledge is thought to lead to auditory misunderstanding and confusion. In early life, this may be reflected in the child's articulation. Poor phonic skills that result from this deficit are thought to contribute to their limited reading and spelling abilities. The auditory tolerance-fading memory group is often thought to have severe auditory-processing problems because those in it are highly distracted by background sounds and have poor auditory memories. However, school performance is not far from grade level, and the resulting reading disabilities stem more from limited comprehension than from an inability to sound out the words. Distractibility and poor auditory memory could contribute to the apparent weakness in reading comprehension. Many of the characteristics of the auditory tolerance-fading memory group are similar to those of attention deficit disorder cases. Both groups are associated anatomically with the AC region. The auditory integration cases can be divided into two subgroups. In the first, the subjects exhibit the most severe reading and spelling problems of the three major categories. These individuals closely resemble the classical dyslexics. We presume that this disorder represents a major disruption in auditory-visual integration. The second subgroup has much less severe learning difficulties, which closely follow the pattern of dysfunction of the auditory tolerance-fading memory group. The excellent physiological procedures to which we have been exposed during this Windows on the Brain conference provide a glimpse of the exciting possibilities for studying brain function. However, in working with individuals who have cognitive impairments, the new technology should be validated by standard behavioral tests. In turn, the new techniques will provide those who use behavioral measures with new parameters and concepts to broaden our understanding. For the past quarter of a century, the SSW test has been compared with other behavioral, physiological, and anatomical procedures. Based on the information that has been assembled, we have been able to classify auditory processing disorders into three major categories.(ABSTRACT TRUNCATED AT 400 WORDS)
