The surge of psychological interest in the metaphor research of the 1970s is noted and the interpretations (theories) of metaphor based on comparison, anomaly, and interaction are presented. Models of metaphorical similarity are reviewed with special attention to A. Tversky's conceptions of similarity and its role in linguistic and cognitive behavior ("Features of Similarity," Psychological Review, 1977, 84, 4, 327-382). An extensive survey of literature on metaphor perception and comprehension is conducted. It is concluded that the field of metaphor studies is rich in theoretical and empirical stimuli but also contains some lacunae and uncertain hypotheses. (LLBA, Modified HA, Accession Number 8700053)
