Evaluating the vividness of mental imagery in different French samples | [Évaluer la vivacité des images mentales dans différentes populations françaises]

The aim of this article is to evaluate the vividness of visual imagery from three different sample groups: a contemporary dance group (n = 24), a group of modified state of consciousness experts (n = 24) and a group of students (n = 48). We argue that the mental imagery activity into low vigilance level and into a modified state of consciousness has a closed link mechanism with vividness of visual imagery. We show that the modified state of consciousness experts reached a significantly higher level of vividness open-eyes score than the group of students. This could mean that higher open-eyes score is a cognitive trait of hypnotic susceptibility linked to specific training. These results stem from research into the close relationship between imagery and perception. We present a French adaptation and a French translation of Vividness of Visual Imagery Questionnaire, too.
