Content, Style, and Emotional Tone of Texts in Introductory Psychology

Random samples taken from six recent textbooks and three older books in introductory psychology were analyzed with respect to linguistic style, emotional tone, and pattern of citation. Newer and older books, individual books, and categories of chapters within books were compared to each other. Analysis suggests that newer books are longer and linguistically more complicated. They also contain proportionally more citations, and more text pages devoted to social psychology and psychopathology than older books. There were several significant stylistic and emotional differences among books and some significant content differences among chapters.
