Of the 40 files used for reliability coding, 17 were identified by both coders as having no morphological errors and 6 were identified by both coders as having no syntactic errors.
The disorder of agrammatic aphasia (or agrammatism), the focus of this article, is classically characterised as a non-fluent aphasia, with associated "telegraphic" speech, word order and morphological errors and reduced ability to produce verbs, although comprehension remains relatively intact (see for example, Goodglass, Kaplan, & Barresi, 2001; Marshall, 2002).
This pattern persists across linguistic domains, so the same negative relationship is seen when looking at the Wug test scores and syntactic errors, and the formulated sentences standard scores and morphological errors.
Morphology was assessed through calculation of morphological errors that were coded for each transcript using the same categories as found in the Wugs test: plurality, third-person singular, past tense, comparative/superlative, present progressive, and possessive.
A ratio comparing the number of morphological errors to the total number of morphological forms found in the transcript was used as the discourse-based measure of morphology.
There was no relation between the composite discourse score and the discourse-based measures of morphological error rate, r (45) = −.19, ns, or syntactic error rate, r (45) = −.19, ns.
The idea is to have a NTSC camera pointing right toward the screen, capture the video when and using morphological filtering to get rid of the errors, and get the location of the finger tips.
GESSA enables the annotation of thousands of landmarks, resulting in the ability to capture morphological variation across subjects at a much finer level of granularity, whilst removing human measurement errors and enabling scalability to large cohorts.
The participants made phonological, morphological, and semantic errors that clearly indicated a reliance on their native language linguistic experiences [54].
That is, the fewer morphological and syntactic errors that the children showed in the discourse, the higher their Wug test and formulated sentences scores tended to be, on average.
