Subclaims¶

q3 i? In an EEG associative learning task, individual d' significantly covaried with ERP scalp topography at 126–148 ms post-stimulus, a period overlapping the P1 component, with source localization implicating the precuneus (BA 7). → Raynal 2024

Raynal, E., Schipper, K., Brandner, C., Ruggeri, P. & Barral, J. (2024). Electrocortical correlates of attention differentiate individual capacity in associative learning. npj Science of Learning. https://doi.org/10.1038/s41539-024-00236-8

q3 · i? · associational · r1

Data-driven TANCOVA on ERPs of 38 young adults during an associative learning task, correlating scalp topography with the behavioral d' index; the analysis "revealed two significant time periods", the first at 126–148 ms.

"The TANCOVA revealed two significant time periods (Fig.1a), the first at 126–148 ms and the second at 573–638 ms post-stimulus onset."

q3 · i? · associational · r1

sLORETA source estimation of the 126–148 ms covariance map in the same EEG study; the analysis "revealed an implication of the pre- cuneus (BA 7)", an area the authors link to attention and visuospatial processing.

"Underlying sources for the first covariance map (Fig. 1c, upper panel) revealed an implication of the pre- cuneus (BA 7), with the highest activation value at MNI coordinates X = 10, Y= −65, Z = 65."

Discussion¶

Related Claims¶

• Global field power is positively associated with associative learning performance (d') at 322–634 ms, with the 322–507 ms period sourced to the middle occipital gyrus (BA 19) — related
• No N1-related topographic difference was found between learners: topographic differences related to learning were only P1 — reports the opposite
• Better associative learning performance is associated with a later (573–638 ms) P3b-like topographic difference with frontal (BA 11) sources — related
