“…Our results indicate that the most common and universal indicators of a narrative's macrostructure are associated more strongly to verbal than to visual working memory capacity. In general, these results are in line with the results of previous studies conducted in children and adolescents [40,43,44], and extend them to previously unexamined narrative variables, such as the type and the completeness of a narrative, its semantic completeness, semantic adequacy and story programming. These results are new and should be confirmed and replicated in future research.…”

“…Although there is a growing body of research on the relationship between working memory and language development, only a few studies thus far have examined the relationship between working memory and children's ability to produce a spontaneous monologue speech, as, for example, when children compose a story (a narrative) [35], or retell it [36]. Among these studies, the overwhelming majority examined this relationship in atypically developing populations or in a comparative paradigm (e.g., atypically vs. typically developing children) [33,[37][38][39][40][41][42]. For example, Dodwell and Bavin [38] reported a significant relationship between various working memory tasks and children's capacity to retell and to create a story (based on pictures).…”

This study examined the relationship between working memory capacity and narrative abilities in 5–6-year-old children. 269 children were assessed on their visual and verbal working memory and performed in a story retelling and a story creation (based on a single picture and on a series of pictures) tasks. The stories were evaluated on their macrostructure and microstructure. The results revealed a significant relationship between both components (verbal and visual) of working memory and the global indicators of a story’s macrostructure—such as semantic completeness, semantic adequacy, programming and narrative structure—and with the indicators of a story’s microstructure, such as grammatical accuracy and number of syntagmas. Yet, this relationship was systematically stronger for verbal working memory, as compared to visual working memory, suggesting that a well-developed verbal working memory leads to lexically and grammatically more accurate language production in preschool children.

“…The cutoff point based on the controls' scores based on the 0–2 scale favors this view, since their results in sentence comprehension were very poor compared to the other tasks ( Table 4 ). Interestingly, Sung et al ( 2018 ) carried out a study on the production abilities of a group of Korean-speaking aphasics, and the results showed that task type related to individual WM capacity, but not to sentence type (active vs. passive).…”

The main goal of the present study is to investigate visual and verbal short-term memory side to side with sentence comprehension in Catalan-speaking subjects with aphasia in comparison with subjects without brain damage. We aim to examine whether there are any significant correlations between their performance on short-term memory and comprehension tasks in order to evaluate the hypothesis that linguistic and memory deficits in aphasia are the result of a dysfunction of a common mechanism, usually short-term memory. Eigthy-four control subjects and twelve individuals suffering from different types of aphasia were assessed using the Catalan version of the Comprehensive Aphasia Test (CAT-CAT), which includes one recognition task and two digit and word span tests to evaluate visual and verbal short-term memory, respectively, as well as a sentence-to-picture comprehension task. The results showed that the performance of subjects with aphasia was significantly low on all tasks. Yet, the logistic regression analysis revealed that the magnitude of the differences between the control and experimental group varied across subtests, and that visual short-term memory was better preserved than verbal memory. The results also showed that there were no significant correlations between memory and language comprehension, which rules out the hypothesis that the deficits observed are due to a common underlying mechanism. Individual variation was also observed, specially on memory subtests, which suggest that memory impairments cannot explain the comprehension deficit in aphasia.

“…This unique attribute allows for a direct comparison of the computational loads between active and passive structures, with sentence length held constant. Studies have indicated that Korean speakers demonstrated greater difficulties in processing passive than active sentences across diverse groups, including older adults ( Sung, 2015a , b ; Sung et al, 2017 ) and clinical populations, such as those with aphasia ( Sung et al, 2018 ) and mild cognitive impairment (MCI) ( Sung et al, 2020 ).…”

ObjectivesThis study examined whether older adults with hearing loss (HL) experience greater difficulties in auditory sentence comprehension compared to those with typical-hearing (TH) when the linguistic burdens of syntactic complexity were systematically manipulated by varying either the sentence type (active vs. passive) or sentence length (3- vs. 4-phrases).MethodsA total of 22 individuals with HL and 24 controls participated in the study, completing sentence comprehension test (SCT), standardized memory assessments, and pure-tone audiometry tests. Generalized linear mixed effects models were employed to compare the effects of sentence type and length on SCT accuracy, while Pearson correlation coefficients were conducted to explore the relationships between SCT accuracy and other factors. Additionally, stepwise regression analyses were employed to identify memory-related predictors of sentence comprehension ability.ResultsOlder adults with HL exhibited poorer performance on passive sentences than on active sentences compared to controls, while the sentence length was controlled. Greater difficulties on passive sentences were linked to working memory capacity, emerging as the most significant predictor for the comprehension of passive sentences among participants with HL.ConclusionOur findings contribute to the understanding of the linguistic-cognitive deficits linked to age-related hearing loss by demonstrating its detrimental impact on the processing of passive sentences. Cognitively healthy adults with hearing difficulties may face challenges in comprehending syntactically more complex sentences that require higher computational demands, particularly in working memory allocation.
