“…Although there is an ongoing debate regarding the superiority of either sequential or simultaneous line-ups (e.g., Wells et al, 2015), research on line-up position effects has not been very consistent, and within both sequential line-ups (e.g., Wilson et al, 2019) and simultaneous line-ups (Clark and Davey, 2005;Palmer et al, 2017;Meisters et al, 2018;Carlson et al, 2019), previous findings vary. Moreover, in eyewitness research, age comparisons are not very common and focused on young adults, with less focus on children, adolescents, and older adults (Erickson et al, 2015;Fitzgerald and Price, 2015;Brackmann et al, 2019). We were also unable to find an investigation of age and position effects, despite earlier findings showing that children and older adults tend to produce more false alarms in target absent line-ups (Bartlett and Memon, 2007;Bartlett, 2014;Fitzgerald and Price, 2015).…”
