According to the neural plasticity account, how does repeated practice at capacity limits benefit untrained working memory tasks?

It induces long-term plasticity in the brain regions that serve working memory, which should benefit any activity that relies on the same underlying brain networks.

What is the second major hypothesis regarding how intensive training improves performance on untrained tasks?

It suggests training encourages more efficient use of existing resources by promoting compensatory strategies to overcome weaknesses or exploit strengths.

How does the paper distinguish between the memory strategies of 'chunking' and 'grouping'?

Chunking involves acquiring long-term representations of sets of items, whereas grouping refers to the volitional subsegmentation of individual items into fewer groups.

What does the strategy mediation hypothesis predict about working memory span performance?

It predicts that variations in strategy use predict individual differences in span performance.

Do adaptive working memory training programs explicitly teach meta-cognitive or strategic techniques?

No, they do not explicitly teach these techniques, but they may promote spontaneous strategy development or enhancement through repeated practice.

Why does the restricted transfer of training gains suggest that strategy development, rather than capacity expansion, is occurring?

Because gains only transfer to tasks with the same structures and materials, showing that training develops strategies for specific task paradigms rather than changing the general underlying substrate.
