Research on motivation in the field of applied linguistics seeks to better understand how and why learners become involved in learning activities and maintain their efforts in this regard. Dörnyei provided a seminal model drawing essentially from cognitive and social psychology (Dörnyei, 2001). In the wake of his reflection, and after investigating motivation in a range of academic contexts, we are now able to present our own model, which is dynamic, weighted, and polytomic (Raby, 2007). After presenting cognitive ergonomics as a new pathway for research in second language acquisition, we shall present the results of our investigations in foreign language learning motivation in technologically enhanced contexts, outlining major methodological difficulties pertaining to this sort of this grounded research.
In this work, no denying the role, or even more so, the value of rational thinking, it is assumed that it is not the only effective tool for man to achieve his valuable goals. It is conjectured here that sometimes irrational thinking is an equally good (and sometimes even better than rational thinking) means of achieving them. In the light of these assumptions, the goal of my work is to indicate the benefits that may be the result of irrational thinking in the colloquial (i.e. unscientific) domain of everyday human practice. The given examples of irrational thinking come from research in the field of cognitive and social psychology and behavioural economics. Their results prove that irrational behaviours (including thinking) are neither accidental nor senseless, and on the contrary systematic and easy to predict, they constitute important arguments for considering the phenomenon of irrational thinking. I also discuss this issue although only to a limited extent.
