Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Diverse contexts aid recognition speed and accuracy, while redundant contexts support better semantic representation, revealing a dissociation between ease of processing and semantic representation. → Johns 2016

q3 · i? · causal · r2

The article's summary of its own combined PLDT and similarity-rating results: "These results reveal a dissociation between ease of process- ing and semantic representation early in learning", with diverse contexts aiding recognition and redundant contexts aiding meaning discrimination.

"These results reveal a dissociation between ease of process- ing and semantic representation early in learning. Subjects in our experiment appear to be more efficient at processing items trained over diverse contexts, recognizing those items more quickly and more accurately."

Discussion¶

Learner Variables¶

Processing Speed — outcome: instruction changes 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 — a narrower finding that bears on this claim
Contextual diversity facilitates episodic recall but impairs recognition — reports the opposite
Semantic integration findings are constrained: integration occurs even with nonsense syllables, limiting schema-based interpretation — related
High-variability passages receive longer study times than low-variability passages
Words encountered in diverse contexts are identified faster, with a mean 26-ms advantage — a narrower finding that bears on this claim
Words higher in contextual diversity and semantic richness are processed more accurately and efficiently in lexical tasks — a broader claim this one bears on
