“…Prior work has shown R, D, P, and M traits improve learnability and usability, and examples of experimental evidence supporting (1) statistical and relational learning of language and/or (2) processing and production in use can be found for redundancy (e.g., Wang and Mintz, 2018;Bahrick et al, 2019;Brehm et al, 2020;Lany and Shoaib, 2020;Tal and Arnon, 2022), degeneracy (e.g., Vulchanova et al, 2015Vulchanova et al, , 2019Gentner and Asmuth, 2017;Thibodeau et al, 2019;Starr et al, 2021), pluripotentiality (e.g., Brocher et al, 2018;Srinivasan et al, 2019;Floyd and Goldberg, 2021), and modularity (e.g., Boers and Lindstromberg, 2012;Conklin and Schmitt, 2012;Christiansen and Arnon, 2017). However, since an individual construction can have multiple overlapping R, D, P, and/or M characteristics, meaning those traits amenable to learning and use are also overlapping, it might be difficult to separate out individually the effects of any particular trait of a certain chunk.…”
