Subclaims¶

q2 i? Mean pre-test to post-test differences were positive for all nine tasks, but standard deviations of change of 0.75 to over 1 indicate considerable individual differences in learning. → Cherry Youn 2022

q2 · i? · associational · r2

Descriptive analysis of pre- to post-test standardized difference scores in the COGITO intensive-practice study (N = 131, ages 20–31 and 65–80). The article reports that "All mean differences for each of the nine cognitive tasks are positive", with standard deviations ranging from 0.75 to over 1 indicating individual differences in learning.

"All mean differences for each of the nine cognitive tasks are positive, suggesting that on average, performance improved during the practice phase and most individuals scored higher at post-test than at pre-test"

Related Claims¶

• Educational-attainment polygenic score associations with pre-test, post-test, and pre-to-post change scores on individual cognitive tasks are small and mostly nonsignificant after multiple-testing correction — related
• A polygenic-score study of learning over 100 days of practice in 131 adults was too small to draw meaningful conclusions about genetic effects on baseline performance and learning — related
