q1 · i? · the article prints no effect size for this finding · causal · r1

The dissertation reports, citing Ericsson and Pool, a digit-recall experiment in which participants initially memorized sequences of up to seven digits after four one-hour sessions, then exceeded that limit through systematic, increasingly challenging practice. This is a second-hand report of the original study, not data collected in this dissertation.

"With continued, deliberate practice—specifically designed to push the limits of cognitive ability—the subjects gradually improved their capacity, eventually being able to recall longer strings of digits consistently."

Discussion¶

Learner Variables¶

• Working Memory — outcome: instruction changes it

• CCT yields small significant gains in nonverbal memory, working memory, and visuospatial skills, but only weak evidence for verbal memory — the general claim this finding bears on, with the studies behind it
