“…First, it is a combined within-subjects and between-subjects design that manipulates the level of a key factor/variable via both within-subjects and between-subjects assignments. This sets apart our experiment from other single-module within-subjects experiments, most of which can be classified into two categories: an experiment with a within-subjects assignment of a key factor accompanied by a separate between-subjects assignment of the key factor (Naoi, Shi and Zhu, 2022;Son and Park, 2022); or an experiment with a within-subject assignment of a key factor and with between-subjects assignments of other factors (Kertzer, Renshon and Yarhi-Milo, 2021;Kertzer and Zeitzo , 2017;Myrick, 2020Myrick, , 2023Renshon, Yarhi-Milo and Kertzer, 2022;Yarhi-Milo, Kertzer and Renshon, 2018;Yarhi-Milo and Ribar, 2022).14 Both categories of single-module within-subjects experiments focus on testing IR-related hypotheses about treatment e ects and utilize within-subjects designs (combined with between-subjects designs) as a tool for doing so (e.g. Bush and Prather, 2021;Kertzer, Renshon and Yarhi-Milo, 2021;Kertzer and Zeitzo , 2017;Myrick, 2020Myrick, , 2023Tingley and Walter, 2011;Yarhi-Milo, Kertzer and Renshon, 2018;Yarhi-Milo and Ribar, 2022).…”
