Protocol analysis
Protocol analysis is a psychological research method that elicits verbal reports from research participants. Protocol analysis is used to studying thinking in cognitive psychology (Crutcher, 1994), cognitive science (Simon & Kaplan, 1989), and behavior analysis (Austin & Delaney, 1998). It has found further application in the design of surveys and interviews (Sudman, Bradburn & Schwarz, 1996), usability testing (Henderson, Smith, Podd, & Varela-Alvarez, 1995) and educational psychology (Pressley & Afflerbach 1995; Renkl 1997).
