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.

With day-increasing emphasis on communication as the chief objective of second language learning, willingness to communicate (hereafter WTC) has come into focus by many researchers, teachers, and foreign language institutes. Previous studies show that WTC is highly correlated with the two variables of perceived competence and communication apprehension. This study aimed to investigate the difference in WTC between male and female English major students at Khorasgan University, Iran. Firstly, 55 English major students were asked to respond to three questionnaires on WTC, perceived competence and communication apprehension. The data was analyzed using independent sample t-test. The results showed no significant difference between male and female students in WTC, perceived competence and communication apprehension. The results related to the effect of language proficiency on WTC, perceived competence, and communication apprehensions were also analyzed using one way ANOVA. The results showed no significant differences between the three different groups of students with different levels of language proficiency in their WTC, perceived competence, and communication apprehension

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.

Articles in general and definite articles in particular can create problems even long after all other aspects of English have been mastered. The present article investigated the learnability problems related to the acquisition of count-mass distinction of English nominals by Persian L2 learners. The theoretical underpinning of the study is the interpretability hypothesis (Tsimpli & Dimitrakopoulou, 2007) arguing that the features which are semantically interpretable can be acquired. To this end, 50 learners constituted the participants of the study and completed a forced-choice elicitation task requiring the use of articles. The results of the study substantiated the interpretability hypothesis. Nonetheless, the advanced L2ers showed a conservative behavior in the mass context. They significantly opted for a/an in wide scope indefinite non-referential de/re context. The findings reveal that article suppliance creates more learnability problems in the plural and indefinite mass contexts compared to the count singular ones.

Gaining insights into the learners’ individual characteristics such as beliefs about language learning and their relationship with learning strategies is essential for planning effective language instruction. Thus, the present study investigated the relationship between beliefs about language learning and learning strategy use in Iranian high school students. This study also compared the correlation of the two variables between males and females and monolingual and bilingual students. The strategy inventory for language learning (SILL) and the beliefs about language learning inventory (BALLI) were used to collect data from four hundred and sixty-two high school students from different cities of the country. Descriptive analyses, Pearson r correlation, and the Fisher z-transformation test, were used to analyze the data. The results revealed that the students used metacognitive strategies most and compensation and affective strategies least. Also, they held strong motivational beliefs about English language learning. Significant positive correlations were found between beliefs and strategy categories. The strongest correlation was found between the students’ metacognitive strategies and their motivation and expectations. The findings revealed no significant difference between the correlation coefficients of monolinguals and bilinguals, and males and females in terms of their language learning beliefs and strategies. Regarding the pedagogical implications of the results, it is discussed that knowledge of students’ language learning beliefs and their preferred strategies can lead teachers and educational authorities toward more informed instructional choices.
