Background: Role of nitric oxide (NO) on expression of morphine conditioning using a solely classic task has been proposed previously. In this work, the involvement of NO on the expression of opioid-induced conditioning in the task paired with an injection of naloxone was investigated. Methods: Conditioning was established in adult male Wistar rats (weighing 200-250 g) using an unbiased procedu...

Designing appropriate materials and activities to enhance vocabulary learning is one of the primary goals of language courses. Among the claims about efficient pedagogical tasks is the Involvement Load Hypothesis (Laufer & Hulstijn, 2001) according to which vocabulary development is contingent on the amount of cognitive process a task involves. Building on the previous research on this hypothes...

introduction: the mechanisms of hepatic encephalopathy are not fully understood. moreover, there is no comprehensive data concerning the effects of nitric oxide (no) system on anxiolytic-like behaviors induced by bile duct ligation (bdl). methods: male mice weighing 25-30 g were used and anxiety-like behaviors were tested using hole-board task. results: the data indicated that cholestasis incre...

This paper presents an experimental test of two contemporary motivation theories in the physical domain. The study combined experimentally-induced achievement goal involvement with autonomous and controlling communication styles based on self determination theory to examine young people’s enjoyment, free-choice behavior and performance in relation to a golf task. Results showed that those in th...

This research showed that appropriate input and suitable contexts for interaction among students can lead to successful  second language acquisition (SLA). This study based on Swain's (2005) notion of collaborative dialogue, aimed to study whether EFL learners participating in negotiation of meaning based tasks collaborate with each other and, if so, to investigate the role of this behavior in ...
