Suggestopedia, the psycholinguistic second language teaching methodology of Georgi Lozanov, has received both favorable and unfavorable evaluations from well-known scholars in the field of language learning. Some suspicious views by Western scholars may be due to the paucity of interpretable scientific evidence for the method's claims. An examination of the underlying principles of the method suggests that they are valid and accurate in light of current theory on the nature of learning, language acquisition, and memory. While the claims that the method induces "superlearning" or "hypermnesia" need more substantial empirical validation, theory on learning may suggest that Lozanov's method should achieve better than average results in learning.
