Examination of a new psycholinguistic tests for people with language disorders

Abstract

The goal of cognitive neuropsychological research of language is to examine the functional level associated with brain injury or developmental disorders and the mechanism of damage to the linguistic knowledge we have in our minds and its use. We are going to develop a cognitive neuropsychological language test that is temporarily named “Psycholinguistic Assessment Battery for Language Disorders (PABLD)”. It can be used in rehabilitation settings for brain-damaged persons and developmentally handicapped children. Discussions on the characteristics of the existing cognitive neuropsychological aphasia test were described to clarify the significance of this test, and the test we developed was described in detail, and the measured contents were examined for every subtest. As a result, it was confirmed that the auditory comprehension tests can evaluate each stage from phonological perception to semantic comprehension, and syntactic comprehension, from one mora to a single sentence, and the factors related to each. The speech tasks for each stage of non-words, nouns, verbs, single sentences, and discourse are possible to analyze the relationship between meaning and phonology. And characters, consisting of reading aloud and reading comprehension and writing are possible to analyze the relationship between meaning, phonology, and characters, respectively. The cognitive neuropsychological analysis can be completed with a number of test items of the same level of language materials as the conventional aphasia test. In addition, the language training tasks based on the results of this test were touched upon, and the background research of the test authors on the test tasks and training tasks was introduced.
