q3 i? The ADAN, LDAP, and BRN components were each observed contralateral to the attended hemifield, resembling the classic adult pattern. → Banerjee Snigdha 2015

Evidence¶

Banerjee Snigdha, Frey Hans-Peter, Molholm Sophie, Foxe John J. (2015).

q3 · i? · causal · r1

ERP results from the cued spatial attention task: ADAN cue × ROI interaction F(1,23) = 10.87, p = .003; LDAP F(1,23) = 12.07, p = .002; BRN F(1,23) = 21.93, p = .000, each driven by greater amplitude contralateral to the attended hemifield.

"We observed top-down attentional modulation of all of the aforementioned components in adolescents contralateral to the attended location, in a manner that resembled what is classically observed in adults, pointing to the fact that these anticipatory spatial attentional mechanisms are already quite mature by mid-adolescence."

Discussion¶

Related Claims¶

• Adolescent anticipatory alpha-band activity lacks the adult-like lateralized suppression pattern, instead showing higher right-parieto-occipital alpha and stronger modulation for cue-left than cue-right — related
• Motivation modulates anticipatory attentional processing: high-interest stimuli produced larger LDAP-period amplitude over right parieto-occipital cortex — 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 higher target-detection sensitivity (d-prime) for high-interest than low-interest stimuli, with better performance in the right hemifield — related
• Motivation did not interact with visuospatial attention effects on post-stimulus visual evoked potentials to imperative stimuli — related
