DESCRIPTION
TRANSCRIPT
Measuring individual difference◦ Reading/operation/counting/spatial span
Two observation1.WM tasks are reliable2.Individual difference is correlated with Higher-
level Cognition.
General or Specific WM ?
Two hypothesis◦ Domain-specific factor
Reading process – reading span task, etc.◦ Domain-general factor
Attention control / Inhibitory process
Average inter-task correlation
Domain-general factor
Correlation of WM span with higher-level cognition
Microanalytic Research◦ WM tasks vs. elementary tasks.
Macroanalytic Research◦ WM vs. Individual difference (Cognition)◦ WM may be a component of gf
WM

The main effect of strategy use may be on the total variance in WM performance.
But it Not mean differential strategy use by low-spans and high-spans accounts for the relationship between WM span and higher-level cognition.
