Background In order to extract knowledge from many heterogeneous sources and to study the phenomena within a social network, it becomes fundamental to analyse in detail each process that takes place within it. Indeed, every process that involves a certain number of entities, cannot be analysed only in a macroscopic way, because each single entity contributes to establish the path to follow for ...

“In watching people thinking in the wild, we learn about their environment for thinking not what is inside them. But the environments of human thinking are not ‘natural’ environments. They are artificial. Humans create their cognitive power by creating the environments in which they exercise those powers.” Hutchins, 1995: 169 This paper deals with cognitive artifacts and their relevance for con...

Context-awareness is an important topic in the wireless sensor networks research field. Wireless sensor networks comprise wirelessly enabled embedded systems for data acquisition and control for a wide array of applications. This paper introduces a novel embedded systems firmware model based on a layered model with context and cognitive planes. The novel architecture focuses on dynamic adaptabi...

The present study aimed to investigate the effect of picture-based vs. context-base method onIranian intermediate EFL learners' knowledge of prepositions. The main question this study triedto answer were whether using picture-based vs. context-based method might enhance higherknowledge of prepositions in Iranian learners of English at intermediate level. To answer thequestions, 45 intermediate ...

This study examined the effect of two different authentic topic-familiar rhetorical L2 listening tasks (expository and argumentative) differing in reasoning demand on the listening comprehension scores of a number of Iranian EFL advanced learners. Sixty homogeneous advanced learners were recruited based on their performance on an English Language Proficiency test (Fowler & Coe, 1976). Then they...

Using referential context in language (e.g., saying “blue pen” when two different-colored pens are visible) makes communication efficient. But it is still unclear which general cognitive processes support the use of context in conversation. Research on pragmatic use in language implicates working memory and inhibitory control; however, no studies have shown evidence of a shared cognitive mechan...
