Abstract
This work associates linguistic and psychological theories in order to develop knowledge concerning the relations between language and cognition. Our application area is the concept of comfort aboard trains. Surveys have been conducted during railroad trips in order to collect the passengers' feeling on this multisensorial concept. Linguistic analyses - regarding lexical, syntactic, morphologic and semantic aspects - were carried out on the corpus of these answers to the questionnaire: speakers' implication has been observed in their discourses, spotting regularities and differences the speakers use. By this way, the semantic properties of comfort aboard trains and the cognitive relationships between those sensorial properties have been identified. The linguistic analysis is further grounded into cognitive hypotheses that deal with the structures of the conceptual representations on comfort aboard trains. We also develop a methodology aiming at the identification of more or less typical properties. Our conclusions concern the productivity of the correlations between linguistic forms and cognitive structures. We comment on how French language and discourse are articulated. And we determine how each of the linguistic, the psychological and the physical disciplines describe differently and sincerely, their own perception of the real world.
