Subclaims¶

q2 i? In episodic memory tasks, higher contextual diversity is associated with better recall but worse recognition performance. → 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 · r2

The chapter reports, citing Lohnas, Polyn, and Kahana (2011) and Anderson (1974), that in episodic memory tests "CD has been found to facilitate recall" while impairing recognition. The chapter attributes these findings to the cited studies without reproducing their effect sizes.

"Similarly, in tests of episodic memory, CD has been found to facilitate recall ( Lohnas, Polyn, & Kahana, 2011), while impairing recognition ( Anderson, 1974; Steyvers & Malmberg, 2003)."

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

• Words higher in contextual diversity and semantic richness are processed more accurately and efficiently in lexical tasks — related
• Diverse and uniform training contexts dissociate: processing ease and semantic representation diverge early in learning — reports the opposite
