The distribution of the allophones of /?/in certain contexts involves free variation and gradient preferences. An organized survey was conducted to elicit the judgments of 37 native Persian speakers concerning the well-formedness of /?/allophonic behavior in five different phonological positions. The results showed that the differences in judgment between the various categories are not just the result of random variations, but are an authentic reflection of the underlying structural differences. Following Boersma and Hayes (1999) and Hayes (2000), a stochastic model is proposed within optimality theory to account for the gradient judgments involved. The model assumes that constraints are arranged along a continuum of constraint strictness, with a band of strictness value assigned to each. When the strictness bands of two constraints overlap, then both rankings of the two constraints are equally available for the generation of outputs, yielding free variant forms. However, when a particular form can be generated only by assigning a constraint a strictness value (/?/ or /??/) within a designated “fringe” of the strictness band, the model generates the form marked with an intermediate degree of well-formedness.

Lexical inferencing is one of the most important strategies in vocabulary learning and it plays an important role in dealing with unknown words in a text. In this regard, the aim of this study was to determine the lexical inferencing strategies used by Iranian EFL learners when they encounter unknown words at both text and sentence levels. To this end, forty lower intermediate students were divided into two groups. For the first group, a text with 10 underlined words was given and for the second group, the same underlined words were given in separate sentences. The students were supposed to read the text and the sentences and to guess the meaning of the underlined words. Then some lexical inferencing strategies were given to them to determine which strategies they used in guessing the meaning of unknown words. The results showed that they used different strategies like using local context and word association in lexical inferencing and also they were more successful at the text level than the sentence one. The results also indicated that they were strategic learners using their own strategies including translation and cultural background knowledge to guess the meaning of the unknown words.

To date, little research on pragmatic transfer has considered a multilingual situation where there is an interaction among three different languages spoken by one person. Of interest was whether pragmatic transfer of refusals among three languages spoken by the same person occurs from L1 and L2 to L3, L1 to L2 and then to L3 or from L1 and L1 (if there are more than one L1) to L2. This study aimed to investigate the production of refusals in three languages and to specify the impact of linguistic knowledge on pragmatic transfer of refusals. To this end, 161 participants in 5groups filled out a Discourse Completion Test (DCT). Data was coded and analyzed according to semantic formula sequences. The data obtained from Kurdish learners of English who were also fluent in Farsi (Trilinguals) were compared with those in other four groups: 1)Native English speakers; 2)Monolingual speakers in Farsi; 3) Monolingual speakers in Kurdish; and 4) Bilingual Farsi learners of English. The results revealed that pragmatic transfer exists in choice and content of semantic formulae. It was also found that the sociocultural norms of English, Farsi, and Kurdish languages differ with respects to the refusal speech act and that individuals’ social power and relative distance play a critical role in performing such a speech act. This research suggests that, in spite of the norm differences existing among these languages, transfer of refusals mostly occurs from Kurdish as L1but not from L2 (Farsi) to L3 (English).

The primary purpose of the present study was to explore whether there was any significant relationship between attitude, self-efficacy, and job satisfaction of Iranian EFL teachers on the one hand, and their choice of teaching strategies. Strategies mostly used by participants of the study with low, mid, and high levels of self-efficacy comprised another purpose of the study. To this end, a questionnaire was developed, piloted, validated, and its reliability was estimated for collecting the required data. Subsequently, based on cluster sampling, 420 male and female teachers from three different educational districts of Tehran responded to the questionnaire. Three separate MANOVAs were run to investigate the effect of teachers’ attitudes on strategies they employed for teaching grammar, vocabulary, and reading. This was followed by the same approach to study the effect of teachers’ self-efficacy and job-satisfaction levels, as well. The results revealed a significant relationship between three factors (attitude, self-efficacy, and job satisfaction) and teachers’ choice of teaching strategies. Moreover, based on the scores obtained from the answers to the questionnaire, participants were classified into three levels of low, mid, and high which corresponded with their degrees of attitude, self-efficacy, and job satisfaction. Accordingly, it was shown that high level of attitude, self-efficacy, and job satisfaction strongly affected teachers’ use of vocabulary teaching strategies; mid to high level of attitude and efficacy affected use of reading and grammar strategies. Also, it appeared that strategies for teaching vocabulary are used more frequently among teachers than grammar and reading.
