"Studies were located using motherese or parentese or fatherese or infant directed speech or infant-directed speech or infant directed talk or child directed speech or child-directed speech or child directed talk or child-directed talk or baby talk AND infant* or neonate* or toddler* as search terms. Both controlled-vocabulary and natural-language searches were conducted (Lucas & Cutspec, 2007). Psychological Abstracts (PsychInfo), Educational Resource Information Center (ERIC), MEDLINE, Academic Search Premier, CINAHL, Education Resource Complete, and Dissertation Abstracts International were searched. These were supplemented by Google Scholar, Scirus, and Ingenta searches as well as a search of an extensive EndNote Library maintained by our Institute. Hand searches of the reference sections of all retrieved journal articles, book chapters, books, dissertations, and unpublished papers were also examined to locate additional studies. Studies were included if the effects of infant-directed speech on child behavior were compared to the effects of adult-directed speech on child behavior. Studies that intentionally manipulated word boundaries (e.g., Hirsh-Pasek et al., 1987; Nelson, Hirsh-Pasek, Jusczyk, & Cassidy, 1989) or used nonsense words or phrases (e.g., Mattys, Jusczyk, Luce, & Morgan, 1999; Thiessen, Hill, & Saffran, 2005) were excluded."
