Bp. Rourke et Kd. Tsatsanis, SYNDROME OF NONVERBAL LEARNING-DISABILITIES - PSYCHOLINGUISTIC ASSETSAND DEFICITS, Topics in language disorders, 16(2), 1996, pp. 30-44
It is usually observed that, following an initial delay in speech acqu
isition, children with the syndrome of nonverbal learning disabilities
(NLD) go on to exhibit well-developed speech and language skills. The
re is, however, comparatively little appreciation of the full extent o
f their deficits in linguistic skills. The NLD syndrome is so named be
cause all of its clinical presentations are thought to arise from defi
cits that are primarily nonverbal in nature. The psycholinguistic dime
nsions of NLD that constitute integral features of its developmental p
icture are thought to arise because of the primary, secondary, and ter
tiary assets and deficits outlined in a developmental model that we ha
ve developed (Rourke, 1989, 1995a). It is clear that a superficial con
sideration of the speech and language of children with NLD would be mi
sleading; there is a great deal to be understood through close examina
tion of the qualitative aspects of their linguistic skills. Our discus
sion of the psycholinguistic dimensions of NLD is presented within the
context of a framework developed by Bloom (1988) who has described la
nguage as consisting of the three basic dimensions of form, content, a
nd use.
