Working memory (WM)

The present study intended to examine the relationship between working memory (WM) and writing performance of a group of Iranian EFL learners and to explore whether learners with different working memory levels perform differently on the fluency, accuracy and complexity of texts produced or not. The necessary data were collected through the argumentative essay writing prompt and a computerized Persian version of reading span test as a measure of learners’ WM capacity. The correlation analysis revealed that there was a significant positive relationship between these two constructs. The results of Multivariate Analysis of Variance (MANOVA) indicated that there were significant differences between High, Mid and Low WM groups in terms of fluency and accuracy of texts produced, but not their complexity. The findings confirmed the importance of WM while working on cognitively challenging tasks such as writing which requires automation and effective management of cognitive resources while writing. On the whole, the present study confirmed the idea that learners with different learning characteristics orchestrate their mental resources in different ways to perform in different phases of writing and part of their difficulties or even capabilities in writing can be attributed to the efficiency with which they apply these resources while dealing with different writing systems (formulation, execution, or monitoring) or engaging in different writing  processes (translating, planning, programming, reading, or editing).

Given the seemingly important link between children’s working memory (WM) and their scholastic performance, it would be a worthwhile research enquiry to explore language learning as one potential way to improve WM. To this end, the present study examined the impact of two language teaching paradigms, namely, Presentation-Practice-Production (PPP) and Total Physical Response (TPR), on children’s WM over time. Seventy participants, aged 8 to 9 years, were administered tests of phonological, visuo-spatial sketchpad and central executive components, and made up TPR, PPP and control groups for a period of three months. Then, a posttest and a delayed posttest were administered to identify whether the treatments led to significant improvements. The results of the 3 WM measures indicated that the 2 interventions led to certain improvements. Whereas TPR led to significant improvements in the central executive, PPP produced significantly higher gains in phonological memory over time. Neither treatment induced any positive impact on the visuospatial sketchpad. The results lend evidence to the trainability of WM. It is also suggested that language learning experiences have long-lasting repercussions and that each language learning experience can impact certain components of WM.

This study investigated the developmental trajectory of Scalar Implicature (SI) comprehension in monolingual Persian-speaking children, examining how linguistic typology, contextual support, and cognitive abilities influence this process in a Subject-Object-Verb language. 60 children divided into 2 age groups (4-5 and 6-7 years), along with 20 adults, participated in a Statement Evaluation Task involving the quantifier "some" ("ba'zi"). The task was designed to evaluate whether participants interpreted "some" as "some but not all" in scenarios where the alternative "all" is true with two contextual conditions: Basic and Enriched, the latter increasing the salience of the "all" alternative. Standardized assessments of Working Memory (WM) and Theory of Mind (ToM) were also administered to explore cognitive correlates. Results showed a significant main effect of Age Group; older children demonstrated higher SI rates (mean=0.61) than younger children (mean=0.35), indicating a developmental increase in pragmatic competence. Moreover, contextual enrichment significantly enhanced SI rates overall, with older children benefiting more notably as evidenced by a significant interaction between age and context. Correlational analyses revealed that WM capacity (Backward Digit Span) was associated with SI performance in the Basic Context, whereas ToM scores correlated with SI rates in the Enriched Context, suggesting dissociable cognitive mechanisms underpin SI comprehension depending on contextual complexity. These findings supported a universal developmental progression from logical to pragmatic interpretations of scalar terms in Persian-speaking children, emphasizing the roles of WM and ToM in the emergence of pragmatic inference. Overall, the study highlighted how contextual cues and cognitive resources differentially facilitate SI understanding, lending support to resource-dependent models of pragmatic development.
