“…Whereas web-based data collection in adults is extensively and successfully used and several well-established RT effects have been replicated in web-based research ( Crump et al, 2013 ; Simcox and Fiez, 2014 ), there are only a few recent web-based studies with children and infants ( Scott et al, 2017 ; Nussenbaum et al, 2020 ; Rhodes et al, 2020 ; Bambha and Casasola, 2021 ; Vales et al, 2021 ). Recent studies collecting RTs with adults and children have shown little to no difference between laboratory-based and web-based samples ( de Leeuw and Motz, 2016 ; Hilbig, 2016 ; Bridges et al, 2020 ; Nussenbaum et al, 2020 ; Morini and Blair, 2021 ; Silver et al, 2021 ; Vales et al, 2021 ) as well as no big differences between browsers (e.g., Chrome and Internet Explorer) or experiment builders (e.g., Pavlovia and Gorilla) ( Kochari, 2019 ; Anwyl-Irvine et al, 2020 ; Sauter et al, 2020 ). In addition, it is difficult to clearly state whether potential differences may be any greater than the difference between two laboratory-based collected samples ( Nussenbaum et al, 2020 ).…”
