The primary aim of the first part of this study is to examine the accuracy and completeness of accounts in eyewitness testimony setting between people who stammer and those who do not. Therefore, there will be one between-subject factor (people who stammer vs. Do not stammer). 

Participants will engage in the same research procedure for the first part of the study: first they will watch a video of a mock crime before being interviewed for their memory of it using standard eyewitness interviewing procedure: first prompting their free recall of the event, before being asked questions based on what they freely recalled. The main planned analysis will examine group effects on recall of details across the interview as a whole (i.e., free and cued recall combined). Further exploratory analyses will examine whether there are group differences in the recall of correct details, errors, and accuracy in eyewitness testimony accounts within free and cued recall (respectively). 

The second part of this study will use a mixed methods approach using an online survey, consisting of both Likert scale questions and open-ended text-based questions. This approach will primarily involve an exploratory qualitative approach to the analysis of participants’ written responses. Quantitative (Likert scale) data will also be reported.
