گرچه بررسی های متعددی جهت ارزیابی تاثیر مؤلفه های پیچیدگی شناختی فعالیت ها بر اساس متغیرهای متمرکزکننده قوای ذهنی ( رابینسون، 2001) انجام شده است، تحقیق کمتری برای بررسی همین تاثیر در راستای متغیرهای پراکنده کننده قوای ذهنی انجام شده است. علاوه بر این، بررسی اثرات تقابلی این متغیرها و شرایط فعالیت بر تولید زبانی زبان اموزان بررسی نشده است. همچنین در بررسی این متغیرها، زبان آموزان کمتر در انجام فعالیت های شفاهی مورد توجه قرار گرفته اند. تحقیق حاضر، به بررسی متغیرهای پراکنده کننده قوای ذهنی بر اساس فرضیه شناختی رابینسون (2001) بر پیچیدگی تولید زبانی زبان­آموزان می پردازد. پس از قرار دادن زبان آموزان در دو گروه بالا و پایین از نظر توانش زبانی، از دو گروه دو نفره خواسته شد که چهار فعالیت زبانی که دارای کمترین تا بیشترین پیچیدگی شناختی بود انجام دهند و در همان حال تعامل زبانی آنان ضبط می شد. بررسی آماری داده ها نشان داد که افزایش پیچیدگی شناختی فعالیتها لزوماً همواره منجر به پیچیدگی کمتر تولید زبانی بین گروهها آنطور که رابینسون ادعا کرده است نمی شود.

Media in general and news in particular constitute indispensable parts of modern life. TV news which contains visual elements in addition to the verbal aspects was used as the corpus of this study. In fact, this research culled out the ideologies of Iranian national television in presenting different issues. To be more precise, three internationally-significant pieces of news reports were chosen: one positive to “Us”, one hostile to “Others”, and one neutral. Then, these news reports were analyzed in detail and their lexical items, grammatical structures, and rhetorical figures were compared to find out about the differences. The results of the study showed that these three reports were presented to the audience via totally different strategies and ideologically-laden words were used to convey positive and negative meanings. In addition, the visual elements (angles, gaze, and distance) corroborated the findings of the verbal sections. The findings of this study show that lexical and grammatical choices are made purposefully in the media. So, it can be said that the results of this research contribute to the fields of linguistics, semiotics, and media.

A critical discourse analysis (CDA) of English language teaching (ELT) textbooks can provide a theoretical description of existing ideological effects in the texts and a means to link linguistic and social practices. This study, thus, seeks to evaluate Summit 2B (i.e., the advanced book of Top Notch series) with a focus on the representation of male and female social actors. In so doing, this study drew on van Leeuwen’s (1996) social actor framework and Halliday’s (2004) transitivity model. To achieve the purpose of this study, content analysis was first carried out in the corpora obtained from the aforementioned textbook to find out the frequency and proportion of various social actors. The results obtained from the tests of significance (i.e., chi-square tests) and the qualitative data analyses revealed that there were some significant differences between males and females concerning role allocation (i.e., activation, subjection, and beneficialization), substitution (personalization/impersonalizaton), and personal pronouns. Compared with females, males were represented as more active, energetic, independent, and assertive forces; males were represented more frequently and placed in high-status positions; they were also individualized more frequently. The results indicated that though females and males were almost equally informalized and indetermined, there was not much serious attempt to eliminate the gender bias in Summit, used as a substitute for other ELT textbooks used in private language institutes in Iran. The findings suggest that textbook writers and publishers should be more cautious about the gender discourse, along with other criteria making ELT textbooks work, because gender bias can affect language learners’ perception and preference for the choice of language in second or foreign (L2) communication.

Recent research in the area of Second Language Acquisition has proposed that bilinguals and L2 learners show syntactic indeterminacy when syntactic properties interface with other cognitive domains. Most of the research in this area has focused on the pragmatic use of syntactic properties while the investigation of compliance with a grammatical rule at syntax-related interfaces has not received due attention. In this study, the compliance of 67 Persian native speakers and 52 Persian speaking L2 learners of English with the Overt Pronoun Constraint (OPC, henceforth) a proposed UG principle, at the syntax-pragmatics interface is investigated. Both groups of participants demonstrated violations of the OPC at the syntax-pragmatics interface. It is argued that the results of this study both confirm and complement Sorace and Filiaci’s (2006) Interface Hypothesis while showing that difficulties at interface contexts are more a result of interface complexities than cross-linguistic influence.
