Similarity of Introductory Psychology Textbooks: Reality or Illusion?

Abstract

Because the perception of extensive similarity in introductory psychology textbooks is important in the textbook selection process, we examined whether this perception was accurate. We systematically reviewed extant research encompassing 6 textbook dimensions and found that perceived similarity is the product of 2 salient, easily accessible, global text variables: chapter topics and organization. Beyond these variables, textbook homogeneity disappears. We consider stereotyping due to the arduous, complex nature of the textbook selection process as an explanation for this misperception of similarity and urge teachers to consider introductory texts more thoroughly to make the best choices for their individual courses.
