Subclaims¶

q3 i? Items trained on low-variability paragraphs were rated as significantly more similar to their target associates than items trained across diverse contexts. → Johns 2016

q3 · i? · causal · r2

In the semantic similarity judgment task following the PLDT, each of ten studied pseudowords was paired with four close associates (40 ratings total). "subjects rated items trained on the low variability paragraphs as significantly more similar to their target associates"; no effect size printed.

"subjects rated items trained on the low variability paragraphs as significantly more similar to their target associates [t(86) = 3.406, p = 0.001] (Fig. 5)."

Discussion¶

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
• Diverse and uniform training contexts dissociate: processing ease and semantic representation diverge early in learning — a broader claim this one bears on
• Random shot selection yields the worst originality-similarity combination, while greedy and constraint-satisfaction selection raise originality without increasing item redundancy — related
• High-variability passages receive longer study times than low-variability passages
• Comprehension ratings diverge across training conditions over repeated passages, with a significant condition-by-trial interaction — related
• Words encountered in diverse contexts are identified faster, with a mean 26-ms advantage — related
