“…Generalizability theory approaches circumvent the sampling variability endemic to splithalf estimates by using all ERP trials from all participants in the estimation of reliability (Baldwin, Larson, & Clayson, 2015;Clayson, Carbine, Baldwin, Olsen, & Larson, 2020;Clayson & Miller, 2017a). Generalizability theory provides a multifaceted framework for estimating score reliability that simultaneously considers multiple sources of variance (Brennan, 2001;Cronbach, Gleser, Nanda, & Rajaratnum, 1972;Vispoel, Morris, & Kilinc, 2018). ERP difference score reliability can be estimated using a multivariate extension of the univariate generalizability theory formulas (see Baldwin et al, 2015;Clayson & Miller, 2017a, for an introduction to the univariate approach).…”
