Replication of Finn & Hudson Kam (2008) The curse of knowledge: First language knowledge impairs adult learners’ use of novel statistics for word segmentation, Exp. 3

Abstract

We replicated Exp. 3 of Finn & Hudson Kam (2008) The curse of knowledge: First language knowledge impairs adult learners’ use of novel statistics for word segmentation, Cognition, 108, 477-499. This experiment was part of a larger project to systematically replicate as many experiments involving statistical word learning in adults as possible.

Second Replication of Finn & Hudson Kam (2008) Experiment 3

“…A previous replication attempt failed to replicate this finding (Iozzo, Lamirato, & Hartshorne, 2017). Our goal here is to attempt to replicate with a larger sample size and hence greater statistical power.…”

Robustness of the adult statistical word segmentation literature: Part 1

“…Either way, the differences in results would be of significant theoretical importance. We have exhaustively documented all such methodological decisiones in individual preprints for each experiment, allowing the reader to judge for themselves and design follow-up experiments if needed (Garcia, Iozzo, et al, 2017;Garcia, van Horne, & Hartshorne, 2017;Hartshorne & Skorb, 2018;Iozzo et al, 2017;Mu et al, 2017;Murdock et al, 2017a,b). Note that our materials, data, and code are available as well (see preprints for details).…”

“…Exhaustive descriptions of each experiment are available in individual preprints posted on PsiArXiv (Garcia, Iozzo, et al, 2017;Garcia, van Horne, & Hartshorne, 2017;Hartshorne & Skorb, 2018;Iozzo et al, 2017;Mu et al, 2017;Murdock et al, 2017a,b). These write-ups include additional methodological and statistical details and provide links to Open Science Framework repositories that contain all data, materials, and code.…”

“…Similarly, the original enforced a five minute break between training segments, whereas ours was self-paced. An exhaustive comparison of the methods in the three replications and the original can be found in the preprints (Garcia, Iozzo, et al, 2017;Garcia, van Horne, & Hartshorne, 2017;Hartshorne & Skorb, 2018;Iozzo et al, 2017;Mu et al, 2017;Murdock et al, 2017a,b).…”
