patterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولEffects of the serotonin releasers 3,4-methylenedioxymethamphetamine (MDMA), 4-chloroamphetamine (PCA) and fenfluramine on acoustic and tactile startle reflexes in rats.
The substituted amphetamines 4-chloroamphetamine (PCA), 3,4-methylenedioxymethamphetamine (MDMA) and fenfluramine (FEN) share the common neurochemical action of acutely releasing central serotonin (5-HT), and yet their behavioral effects are quite different. The present study evaluated the effects of these compounds on acoustic and tactile startle reflexes. PCA and MDMA were qualitatively simil...
متن کاملGender differences in hyperthermia and regional 5-HT and 5-HIAA depletion in the brain following MDMA administration in rats.
In the present research the role of gender in MDMA-induced hyperthermia and serotonin depletion is studied by injecting male and female male rats with MDMA or saline 3 times (i.p.) with 3h interval at dosages of 0.3, 1, 3 or 9 mg/kg at an ambient temperature of 25°C. The acute hyperthermia following the higher dosages was much stronger in males than in females. After the highest dose, body temp...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولThe effect of MDMA (3,4-methylenedioxymethamphetamine) on the 5-HT synthesis rate in the rat brain: an autoradiographic study.
The effect of MDMA (3,4-methylenedioxymethamphetamine), a psychotropic amphetamine derivative, treatment on the rate of serotonin (5-hydroxytryptamine; 5-HT) synthesis in the rat brain was studied by autoradiography using alpha-[14C]-methyl-l-tryptophan method. Three different treatment protocols were compared to the control (saline) treated rats: (1) rats treated twice with 10 mg/kg every 12 h...
