theorists suggest that literature allows readers to access intimate emotional aspects of a person's character that would not be obvious otherwise. that literature aids the psychological development and understanding of the reader, allowing someone to access emotional states from which they had distanced themselves. d. mitchell, for example, explains how one author used young-adult literature to describe a state of "wonder" she had experienced as a child. some researchers focus on the significance of literature in an individual's psychological development. for example, language learning uses literature because it articulates or contains culture, which is an element considered crucial in learning a language. this is demonstrated in the case of a study that revealed how the presence of cultural values and culturally familiar passages in literary texts played an important impact on the performance of minority students in english reading. psychologists have also been using literature as a tool or therapeutic vehicle for people, to help them understand challenges and issues - for example in the integration of subliminal messages in literary texts or in the rewriting of traditional narratives to help readers address their problems or mold them into contemporary social messages.
