“…One especially productive approach has been to utilize training paradigms to teach participants categories across novel or unfamiliar exemplars. In addition to advancing theoretical accounts of category learning and generalization, these literatures have informed real-world applications in second-language acquisition (Lim & Holt, 2011;Reetzke et al, 2018), science learning (Eglington & Kang, 2017;Goldwater et al, 2022;Nosofsky et al, 2018), social group recognition through faces and voices (Lavan, Burton, et al, 2019;Retter et al, 2020), stereotyping (Hugenberg & Sacco, 2008) and approaches to building effective educational materials (Carvalho & Goldstone, 2021;Nosofsky et al, 2019). Many studies of category learning have examined aspects of training that best support effective learning, informing both theory and application.…”
