Validation d'une version française de l'inventaire rationnel-experientiel (REI) et application au tabagisme

The Rational-Experiential Inventory REI (Pacini and Epstein, 1999) is a self-administered test comprising two scales measuring the attitude of respondents towards two thinking styles respectively referred to as the rational and the experiential thinking styles. Two validation studies were conducted using a new French-language version of the REI. The first study confirms the validity of the French translation. The second study, which is concerned with the REI's construct validity, assesses the questionnaire's capacity to discriminate between a group of smokers and a group of non-smokers. Both studies give generally satisfactory results. In particular, the advantages of using the two-dimensional REI rather than the better known Need For Cognition scale (Cacioppo & Petty, 1982) are made quite clear.

Voyages astraux et hors du corps. Héautoscopie, extase et hallucinations expérientielles d'origine épileptique [Astral and out-of-body voyages. Heautoscopy, ecstasis and experimental hallucinations of epileptic origin]

We report a 38 year-old patient who had temporoparietal epilepsy and unusual ictal "out of body" experiences that remained undiagnosed for more than ten years, until her admission for a motor seizure of the left hemibody. Out of body episodes were experienced as intense and ecstatic astral journeys. EEG showed a bilateral extension of epileptiform abnormalities to the parietal regions, predominantly on the right side. We discuss the various forms of heautoscopy and their putative mechanisms. We suggest that a disturbance in representing space in independent extrapersonal and personal coordinates might be as crucial as the elusive hypothesis of a body schema disorder. Combined involvement of the parietal neocortex and temporolimbic structures might allow those experiences to gain a subjective vividness which appears to be indissociable from normal conscious experiences.
