This issue presents the original English version and a French translation of a text written at the Sofia Institute of Suggestology around April 1971. The document defines suggestology and suggestopedia, and traces the development of the suggestopedic method, from the first collective experiments aimed at attaining suggestive hypermnesia carried out in 1964 at the Post-graduate Medical Institute in Sofia, Bulgaria, to the experiments going on at the present time at the Research Council of the Centre on Suggestology of the Ministry of Education in Sofia. The salient characteristics of this method are seen as suggestive hypermnesia and psychohygiene. A chronological summary of Lozanov's activities is followed by a review of two works relating to suggestopedia and an annotated bibliography dealing with suggestopedia and foreign language instruction.
