Motivation and the cognitive effort in idiomatic phraseology
It is common to state that idioms represent a major challenge in learning and use face to free speech words units. However, there are difficulty degrees when it comes to idiom meaning processing. This article aims to answer the question of why there are idioms that it takes a hard work to motivate, whereas there are others that, whatever their familiarity or context dependence, are immediately interiorized and understood. Operating with the cognitive notions of image and particularly with its level of abstraction and concretization, global or individual reading, direct or indirect and contiguity and similarity linking, this paper suggest a four-level scale based on cognitive effort in motivating and understanding idioms.
