Society for the Teaching of Psychology (APA Division 2) OFFICE OF TEACHING RESOURCES IN PSYCHOLOGY (OTRP) Department of General Academics, Texas A&M University at Galveston, P. O. Box 1675, Galveston, TX 77553 FREQUENTLY CITED CONCEPTS IN CURRENT INTRODUCTION TO PSYCHOLOGY TEXTBOOKS Derrick L. Proctor and Alisa M. E. Williams, Andrews University Overview Thirty-three full-length Introduction to Psychology texts were used to determine the most frequently cited concepts. A total of 4902 unique concepts were identified. Core concepts are presented in a series of four tables. Description Data from 33 full-length Introduction to Psychology texts, copyrighted from 2003 to 2005, were used to determine the most frequently cited concepts. The glossary of each text was entered into a database. After all terms were entered, synonyms and abbreviations were combined yielding 4,902 unique concepts. Concepts found in 50% or more of the texts were designated as “core concepts” and are presented in a series of four tables. The information is useful to teachers of the introductory class because it directs them to the most frequently cited concepts and which ideas are more important than others. Arguably, students are better served by learning the most frequently used concepts, or core concepts, in all texts rather than restricting their learning to the perspective of the teacher or the perspective of the various text authors.

In tailoring their courses, teachers may unintentionally omit important topics, or emphasize trivial ones. Using the data presented in this resource on frequency and extent of textbooks’ coverage of various concepts helps instructors deliver more balanced, comprehensive courses in introductory psychology. Current Introduction to Psychology texts have similar, if not identical, chapter titles and sequence of chapters, but the terminology used in the texts sometimes differs considerably (Griggs, Bujak-Johnson, Proctor, 2004; Griggs, Jackson, Christopher, Marek, 1999). Additionally, teaching Introduction to Psychology has become more complex with more areas and subspecialties in the field of psychology. The data presented in this resource clarify which concepts are most frequently cited in Introduction to Psychology texts. Method Thirty-three full-length Introduction to Psychology textbooks, copyrighted from 2003 to 2005, were used to determine the most frequently cited concepts. The glossary of each text was entered into a database. All terms were entered into the database as separate entries unless the terms were identical or if they were singular/plural forms of the same term. For example, defense mechanism and defense mechanisms were entered as the same term. However, if one text used the term unconditioned stimulus and other texts used the term unconditioned stimulus (UCS), or just US, these were entered as separate terms. This process continued until all terms from all texts had been entered. After all terms were entered, synonyms and abbreviations were combined with the most frequently used form of the concept. When we were uncertain whether particular terms were synonyms, we consulted The Dictionary of Psychology (Corsini, 1999). Frequently, terms that were used by only one or a few authors were not found in the dictionary, and might be classified as “egocentric” terms. Results A total of 6,826 different terms were identified initially. After combining synonyms and abbreviations 4,902 unique concepts emerged. Of these, 428 were found in 50% or more of the texts. We designated these as “core concepts.” Only 33 concepts were listed in 100% of the textbooks. Table 1 lists the 428 core concepts in alphabetical order. Table 2 lists the 428 terms in order of importance or citation frequency. Table 3 lists the 428 concepts in alphabetical order, according to the chapter of the text where they are most likely to be found. Table 4 lists the 428 concepts in order of frequency, according to the chapter of the text where they are most likely to be found. Of note, no text includes 100% of the core concepts. The highest coverage of core concepts is 87.5%, with most texts covering 60% to 80% of core concepts (Griggs, Bujak-Johnson, & Proctor, 2004). At the beginning of a quarter/semester, teachers might compare a new textbook to the information in Tables 1-4 to identify the core concepts in each chapter, as well as additional concepts that have been omitted from the text. Handouts for students can provide information about the relative importance of each concept and the percentage of texts citing each core concept. Terms that are in the core concept list that have not been included by that particular text also can be listed along with the percentage of texts that do include the concept. One way to use the terms is especially relevant to psychology majors. Concepts presented in the largest number of texts are more likely to appear in other courses as well. 2 Students preparing to take the Psychology GRE may find it helpful to review the concepts that are frequently used in the first course in psychology. Core concepts may be used in conjunction with whatever else the teacher chooses to emphasize. Although texts may emphasize a particular viewpoint (cognitive, biological, evolutionary, etc.), the core concepts identify a conceptual foundation agreed upon by authors from many perspectives.
