Background : Verb Inflection errors are frequent in individuals with aphasia, yet, different features of it are not equally impaired. Tense and aspect are more vulnerable than morphemes of agreement or mood. The present study was aimed at reviewing the studies of grammatical tense and aspect in aphasia.
Materials and Methods: Two databases of PubMed and Google Scholar were searched with the following syntax: “Aphasia” AND (“Time” OR “Aspect” OR “Tense” OR “Time reference” OR “Verb Inflection”). Articles that were published in English or Persian in peer-reviewed journals from 1980 to 2023 were included. General information including the names of the authors, year of publication, language, number of participants with aphasia, type of aphasia, the applied tests, and the assessed skills were extracted.
Findings: 49 studies, in 21 different languages were identified. 35 studies were conducted on non-fluent aphasia, 3 studies on fluent aphasia. The Test for Assessing Reference of Time (TART) was the only formal test used in 11 studies. 38 studies had used self-made tasks including sentence completion, picture description, repetition, connected speech, grammatical judgment, and sentence-picture matching. Of the studies reviewed, 15 studies reported deficits in the past tense, 2 studies reported deficits in the future tense, 6 studies reported deficits in both the past and future tenses, and 13 studies reported no differences between tenses despite the deficits in time. Of the 14 studies of aspect, 8 studies reported deficits in perfct aspect and 3 studies reported deficits in imperfect aspec.
Conclusion: Tense and aspect deficits can be considered as noticeable symptom of nonfluent aphasia. It seems that the past tense and perfect aspect are more damaged. Researchers attribute this to the limited working memory capacities of people with aphasia and the nature of the task used in the research.
