• Abbreviations and acronyms should be spelled out at their first mention unless they are commonly used as words (e.g. "IQ").
  • Equations in the text should be numbered using consecutive Arabic numerals in parentheses at the right margin.
  • In-text citations should include the last name of the author(s) the year of publication and page numbers (when quoting directly from a work or referring to specific passages). If the author’s name is in the text follow it with the publication year in parentheses. Example: "…in a study by Binder (2010)." If the author’s name is not in the text enclose the last name and publication year in parentheses. Example: "...whenever it occurred (Bills 2004)." Pagination follows the year of publication after a colon with no space between the colon and the page number. Example: "...according to Fomby (2005:71)." Give both last names for joint authors. Example: "... based on prior evidence (Grodsky and Muller 2009)." If a work has three authors cite all three last names in the first citation in the text; thereafter use et al. in the citation. If a work has more than three authors use et al. throughout. Example: "...obtained the same results (Liebler Ruggles and Fitch 2007; Hauser et al. 2008). However ... (Liebler et al. 2007)." Separate a series of references with semicolons and list the series in alphabetical or date order (but be consistent throughout the manuscript). Example: "…for more information (Park 2006; Schofer 2009)."
