3. An Individual-Differences Perspective On Working Memory(WM)
Measuring individual difference
Reading/operation/counting/spatial span
Two observation
WM tasks are reliable
Individual difference is correlated with Higher-level Cognition.
General or Specific WM ?

4. Which Hypothesis is correct?
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

5. View in Research Microanalytic Research Macroanalytic ResearchWM
Microanalytic Research
WM tasks vs. elementary tasks.
Macroanalytic Research
WM vs. Individual difference (Cognition)
WM may be a component of gf
Elementary task
Elementary task gf WM

6. The Role of Strategies?
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.

7. Toward a Broader Perspective on the Role of WM in Higher-Level Cognition
Domain-general hypothesis
Microanalytic
Individual difference Factor is elementary attention.
Macroanalytic
WM plays important role in cognition.
WM : bottom-up
Integrating coming information with preexisting knowledge.
