Common Brain Network Dynamics Capture Attention Fluctuations in Tasks and Movies

by Clinical Neuropsychologist Online | Tuesday, September 1, 2026 | Cognitive Neuropsychology

AbstractAttentional states are highly dynamic and variable, fluctuating from moment to moment and showing stark differences across contexts. To what extent does functional brain reorganization capture variability in attentional states? In the present study, we utilize...

Neural Sensitivity to Word Frequency Modulated by Morphological Structure: Univariate and Multivariate Functional Magnetic Resonance Imaging Evidence from Korean

by Clinical Neuropsychologist Online | Tuesday, September 1, 2026 | Cognitive Neuropsychology

AbstractA central question in psycholinguistics in visual word recognition is whether morphologically complex words are obligatorily decomposed into stems and affixes during visual word recognition or whether whole-word access can occur when forms are frequent and...

Human Gaze Behaviors Track Abstract Stimulus Categories

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractCategorization, or the ability to group stimuli according to behavioral relevance, is a cornerstone of abstract cognition. Neurophysiological studies in nonhuman primates have revealed that category-selective signals are robustly encoded in oculomotor...

Gesture-based Instruction Enhances Neural Synchrony and Predicts Children’s Mathematical Learning

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractTeachers’ hand movements during instruction can influence how children learn mathematics, but not all movements are equally effective. Gesture-based instruction on problems such as 4 + 2 + 5 = __ + 5—where the teacher places a V-shaped hand under the 4...

Hippocampal Reactivation Trades Episodic Detail for Semantic Gist in Human Memory

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractMemory must balance preserving episode-specific details with extracting generalizable structure. Here, we test whether spontaneous hippocampal reactivation during postencoding rest actively transforms memories by strengthening semantic gist at the expense of...

Distinct Patterns of Directed Brain Connectivity in Focused Attention, Open Monitoring, and Loving Kindness Meditation: An Electroencephalographic Granger Causality Study with Long-term Meditators

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractThe present study applied spectral Granger causality (GC) analysis to EEG recordings obtained during focused attention meditation (FAM), open monitoring meditation (OMM), and loving kindness meditation (LKM) in highly experienced meditators. The aim of the...
