Measurement Model of Working Memory Associated Brain Regions Activation during the 2-back Task.
| Factors and Indicators | B (SE) | λ (SE) | R2 | 95%CI of λ |
|---|---|---|---|---|
| WM Brain Regions Activation | ||||
| WM Brain Activation → IPL | 1.00 (.00) | .85 (.04) | .72 | [.77, .93]*** |
| WM Brain Activation → MFG | 1.16 (.14) | .83 (.04) | .69 | [.75, .91]*** |
| WM Brain Activation → RInsula | .99 (.11) | .82 (.03) | .56 | [.75, .89]*** |
| WM Brain Activation → RCingulate | .84 (.12) | .75 (.06) | .67 | [.63, .87]*** |
Note. WM Brain Activation = Working memory associated brain regions activation during the 2-back task latent factor. IPL = Inferior parietal lobule. MFG = Middle frontal gyrus. RInsula = Right insula. RCaudate = Right cingulate/ right medial frontal. Model fit is excellent: χ2 (2) = 2.16 (p = .34). CFI = 1.00, TLI = 1.00, RNI = 1.00, RMSEA = 0.03, SRMR = .01.
