Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Alpha power was higher over the right than left parieto-occipital ROI in both cue conditions, and significantly higher for cue-left than cue-right over the right ROI. → Banerjee Snigdha 2015

q3 · i? · causal · r2
Anticipatory alpha (TSE) ANOVA in 24 adolescents: cue × ROI interaction F(1,23) = 6.45, p = .018; main effect of ROI F(1,23) = 13.02, p = .001. Paired t-tests showed "significantly higher alpha power for the cue left versus cue right condition over the right parieto-occipital ROI, t(23) = 2.30, p = .031."
"Instead, there was higher alpha power over the right vs left ROI for both cue left and cue right conditions, although this difference was less pronounced for the cue right condition"

Related Claims¶
- Adolescents show adult-like anticipatory broadband ERP attention components (ADAN, LDAP, BRN) contralateral to the attended location — related
- Exploratory analysis reveals sustained greater anticipatory activation for high versus low motivation conditions from 700–1100 ms post-cue over parieto-occipital scalp — related
- Adolescents show adult-level dlPFC beta-band power but lower FEF alpha-band power and weaker dlPFC/FEF beta-alpha cross-frequency coupling during antisaccade preparation — related
- Motivation modulates anticipatory attentional processing: high-interest stimuli produced larger LDAP-period amplitude over right parieto-occipital cortex — related
