A means for the classification of results of research examining verbal intellectual ability is proposed. A review of co relational studies of verbal intellectual ability was also conducted. The role of verbal ability in various standard factor-analytic theories of intelligence was examined with special emphasis on research conducted in the Serbian language. It was concluded that verbal ability plays a significant role in all factor-analytic models and theories of intelligence, regardless of whether this was explicitly or implicitly identified by their authors. Moreover, a strong tradition of research of verbal intellectual ability in the Serbian language was found to exist.
