The current paper presented theoretical assumptions behind language learning strategies (LLS) and an overview of methods used to identify learners' strategies, first, and then summarized what have been reported from large number of descriptive studies of strategies by language learners. Moreover, the paper tried to present the variety of…

This article is concerned with how computer science, and more exactly computational complexity theory, can inform cognitive science. In particular, we suggest factors to be taken into account when investigating how people deal with computational hardness. This discussion will address the two upper levels of Marr's Level Theory: the computational…

Offers a sketch of a concept called the "liminal state" that may represent a central element of designing and a condition that facilitates the best design products and processes. A definition of "liminal state," some contexts in which it may occur, and some areas where liminal states might improve performance are given.…
