Izchak Schlesinger was a professor of psycholinguistics at the Hebrew University of Jerusalem. His research focused primarily on language acquisition and was presented in a series of books and studies that developed a semantic approach as an alternative to generative linguistics. He also examined the structure of argumentation through an interdisciplinary perspective that drew on Talmudic discourse and was among the first researchers of Israeli Sign Language. In later years, he was awarded the Israel Prize in Psychology for his contributions to the field.
