Subclaims¶

q3 i? Subjects responded significantly faster to pseudowords trained in high-variability paragraphs, with a mean 26-ms advantage. → Johns 2016

Evidence¶

Johns 2016¶

Johns, B. T., Dye, M., & Jones, M. N. (2016). The influence of contextual diversity on word learning. Psychonomic Bulletin & Review. https://doi.org/10.3758/s13423-015-0980-7

q3 · i? · causal · r2

Response time measure of the same pseudolexical decision task: "Subjects were significantly faster at identifying words that appeared in high variability paragraphs" compared with uniform-context words. Only the test statistic and the 26-ms mean difference are printed; no standardized effect size.

"Subjects were significantly faster at identifying words that appeared in high variability paragraphs [t(86) = 2.297, p < 0.05] (Fig. 4; right), with a mean 26-ms advantage."

Discussion¶

Learner Variables¶

• Processing Speed — outcome: instruction changes it

Related Claims¶

• Words higher in contextual diversity and semantic richness are processed more accurately and efficiently in lexical tasks — the general claim this finding bears on, with the studies behind it
• Words encountered in diverse contexts are recognized more accurately in a pseudolexical decision task — related
• Uniform (redundant) contexts yield higher semantic similarity ratings than diverse contexts — related
• Diverse and uniform training contexts dissociate: processing ease and semantic representation diverge early in learning — a broader claim this one bears on
