Subclaims¶

q2 i? In naming and lexical decision tasks, words scoring higher on measures of contextual diversity and semantic richness elicit more accurate and efficient responses, a result the chapter reports as replicated with different language materials and extended to young readers. → Jones 2017

Evidence¶

Jones 2017¶

Jones, M. N., Dye, M., & Johns, B. T. (2017). Context as an Organizing Principle of the Lexicon. Psychology of Learning and Motivation, Volume 67. https://doi.org/10.1016/bs.plm.2017.03.008

q2 · i? · the article prints no effect size for this finding · review · r3

The chapter's narrative review of multiple studies reports that in naming and lexical decision, "words that score higher on measures of CD and semantic richness are responded to more accurately and efficiently," with replication across different language materials and extension to young readers. No effect sizes are printed.

"In semantic tasks, such as naming and lexical decision, words that score higher on measures of CD and semantic richness are responded to more accurately and efficiently (Adelman & Brown, 2008;Jones et al., 2012; McDonald & Shillcock, 2001; Pexman, Hargreaves, Siakaluk, Bodner, & Pope, 2008 ), a result that has been replicated using different language materials and lexical data"

Studies bearing on this claim¶

Does meeting a word in more varied contexts, rather than only more often, make it better known? This table gathers the studies behind this claim and the 4 narrower claims that bear on it: 2 distinct studies (1 review, 1 causal), q2–q3, 0 of 2 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.
