Working memory capacity

مطالعه حاضر به پردازش بندهای موصولی مبهم توسط فارسی زبانان فراگیر انگلیسی به عنوان زبان دوم که دارای درجات متفاوتی از ظرفیت حافظه فعال و تسلط به زبان انگلیسی هستند می پردازد. بندهای موصولی مورد مطالعه از آن جهت مبهم هستند که میتوانند به یکی از دو عبارت اسمی ماقبل خود اشاره کنند. هدف اصلی مقاله بررسی تاثیر معنا بر نحوه رفع ابهام این گونه جملات می باشد. بدین ترتیب رابطه معنایی بین فاعل/فعل عبارت اصلی و یکی از دو عبارت اسمی که قبل از بند موصولی آمده اند ایجاد شد. طبق پیش بینی مدل انتشار فعال سازی، احتمال این که عبارت اسمی که به واسطه ارتباط معنایی با فاعل/فعل در ذهن فعال شده به عنوان مرجع بند موصولی انتخاب شود بیشتر خواهد بود. نتایج دو آزمایش صورت گرفته نشان داد که ارتباط معنایی نقشی در رفع ابهام بندهای موصولی ندارد. بلکه فارسی زبانان فراگیر انگلیسی تحت تاثیر اطلاعات نحوی جمله میباشد. همچنین نتایج نشان داد که ظرفیت حافظه فعال افراد به میزان معناداری با نحوه ابهام زدایی از این گونه جملات ارتباط معکوس دارد.

This study aims at investigating whether Persian native speakers highly advanced in English as a second language (L2ers) can switch to optimal processing strategies in the languages they know and whether working memory capacity (WMC) plays a role in this respect. To this end, using a self-paced reading task, we examined the processing strategies 62 Persian speaking proficient L2ers used to read sentences containing ambiguous relative clauses in their L1 and L2. The results showed that L2ers adopt the same strategy as that used by English native speakers in both of their languages, indicating a target-language like parsing pattern in their L2 and an attrition of L1 parsing routine. Additionally, their attachment preferences were not modulated by WMC in L2. This result highlights the “skill-through-experience” position adopted by researchers who question the role of WMC in L2 syntactic parsing. However, high-capacity L2ers' preferences in L1 had attrited (becoming English-like), and low-capacity ones had no preference. This modulation, too, can bear out the above position owing to the observation that L2ers failed to differentiate between their L1 and L2, and particularly that their differing WMCs did not contribute to native-like performance in their L1.

This study aimed at investigating the effect of Preview, Question, Read, Summarize (PQRS) Strategy on EFL students’ writing ability by considering their working memory capacity (WMC) levels. It involved Indonesian English as a foreign language (EFL) students of English Department in Universitas Negeri Malang, one of the leading universities in Indonesia. This study applied a quasi-experimental design and compared the writing ability of two intact groups of students. The data were collected by using writing tests and a WMC test. The results of the research revealed that there was a significant difference between the students who were taught by using the PQRS strategy and those who were not taught by using that strategy. However, there was no significant difference in the writing ability of the EFL students across WMC levels. Theoretically, this study supports the important roles of integrated reading-writing instruction in the teaching of writing. Pedagogically, in the teaching of writing, EFL teachers might apply the PQRS strategy as part of integrated reading-writing instruction to EFL students regardless of the difference in their WMC levels.

This study explored the competition between semantic and morphosyntactic processing in L1 and L2. In addition, the relationship between working memory capacity (WMC) and L2 semantic-morphosyntactic processing was scrutinized. To this purpose, 73 Persian learners of English as a Foreign Language (EFL) participated in an offline grammaticality judgment test (GJT), an L1 as well as an L2 semantically-primed test, and a WMC test. The results showed that L1 morphosyntactic processing was not affected by semantic priming. But, L2 morphosyntactic parsing decisions, irrespective of the participants’ WMC, was significantly influenced by semantic priming, indicating that L2 morphosyntactic knowledge in learners' interlanguage system might be shaky and subject to communicative aspects of input. Additionally, the findings revealed a significant relationship between the participants' WMC and their L2 semantic/morphosyntactic processing. The findings of the study provide some implications for foreign language teachers with regard to teaching morphosyntactic aspects of language and correcting morphosyntactic errors.

This study aimed to determine the effectiveness of Gagne’s model of instructional design on the attention and working memory capacity of students with attention deficit hyperactivity disorder. This study adopted a quasi-experimental design with pretest-posttest and a control group. The statistical population of the current research consisted of all fifth-grade female students with attention deficit hyperactivity disorder in Tabriz in the academic year 2021-2022. In this study, 30 students with attention problems (scores higher than 72 in the Connors Parent Questionnaire) were selected as the sample and randomly assigned to the experimental and control groups. The experimental group underwent eight training sessions, four sessions per week, each for 30 minutes, using the Gagne’s training model while the control group did not receive any training. It should be mentioned that the computer version of the selective and divided attention and working memory tests were used to collect data. The data were analyzed using multivariate analysis of covariance (MANCOVA) and SPSS 22 software. The results showed that Gagne’s model of instructional design is effective in increasing divided attention (P <0.048), selective attention (P <0.018), reducing reaction time (P <0.009), and increasing working memory capacity (P <0.047) in students with attention deficit hyperactivity disorder. Therefore, it is suggested that the content of courses requiring great attention and concentration be designed using Gagne’s model of instructional design and presented to students in order to increase the amount of divided attention , selective attention and working memory capacity and reduce reaction time.

This synthesis reviews the methodological issues in empirical studies investigating the effect of working memory capacity (WMC) on relative clause ambiguity resolution where results have failed to be consistent cross-linguistically and even intra-linguistically. This discrepancy might have occurred due to ‘methodological inconsistencies’ in the design (Liu & Brown, 2015), administration, and scoring of WMC measures. This study aimed to investigate the aggregative and developmental status of the methodological practices of WMC measures and describe how transparently such practices have been reported. Based on a comprehensive search, 39 experiments were retrieved from 25 studies, culminating in a collection of studies with a time span of 22 years from 1999 to 2021, and coded for 46 features. Results revealed that although over the past 22 years, the field has witnessed significant improvements in the employment of WMC tests, there are still a lot of variations and inconsistencies calling for attempts to raise methodological awareness among researchers to afford more attention to quality and transparency in reporting WMC tests. The article concludes with a call for reform in standardizing WMC tests and a number of other recommendations for future primary and secondary research.
