Effet Charlie et réactions émotionnelles inconscientes. Intérêt et limite d'une expérience psychophysiologique

Despite the simplification of hardware from galvanic recording, unconscious reactions were obtained in this population of students. But, in general, results using EDA are especially valuable in large samples (Ben-Shakhar, 2012). This experimental study simply checked statistical variations related to the effects of current events in the study population. Care must be taken with these analyzes because this measure remains delicate. It is common to find in some articles illusory interpretations of the psyche (Poirel, 1994). In this world of “big data”, new devices are attractive but sometimes they give an impression of omnipotence among researchers who use powerful tests, but are offset by the object of study. Pedagogically, students (and future researchers) must master the psychophysiological parameters and key statistical concepts, but should also be aware of the flaws in these measures.
