Hemispheric Dissociation Revealed by Attentional Isolation and Transcranial Random Noise Stimulation

by Clinical Neuropsychologist Online | Wednesday, July 1, 2026 | Cognitive Neuropsychology

AbstractProlonged cognitive imbalance, induced by directing attention to one visual field, can paradoxically enhance performance in the opposite, nonattended visual field. This effect is likely driven by the brain’s homeostatic mechanisms that regulate...

When Syntax Needs Semantics: A Cross-linguistic Time–Frequency Analysis of Cantonese and English

AbstractThis study investigates whether syntactic unification, the process whereby lexical items are combined into a structured sentence representation, operates independently of semantic influence in Cantonese. Specifically, we compared Cantonese with English to...

Prestimulus Alpha Power Enhancement via Transcranial Alternating Current Stimulation Does Not Influence Visual Contrast Detection

by Clinical Neuropsychologist Online | Monday, June 1, 2026 | Cognitive Neuropsychology

AbstractVariability in visual contrast detection has been linked to prestimulus alpha oscillations, yet whether modulating alpha power can causally influence perception remains unclear. In this sham-controlled, single-blinded, within-participant study, we applied...

Competition for Limited Visual Capacity Follows Feedforward Processing of a Distractor

by Clinical Neuropsychologist Online | Monday, June 1, 2026 | Cognitive Neuropsychology

AbstractThe present study tested central predictions of our conceptual framework “distraction under competition” (DUC), including the extent to which semantic processing of emotional cues triggers competitive interactions among multiple stimuli. In situations in which...
