Sampling without Vision: Auditory Performance Fluctuates in Congenitally Blind Individuals

by Clinical Neuropsychologist | Wednesday, October 1, 2025 | Cognitive Neuropsychology

AbstractIn the past decade, studies have shown that attention fluctuates at ∼8 Hz, alternating between intervals of increased and decreased visual performance. This modulation of performance, which has been observed primarily in the visual modality, also manifests in...

Activation Pattern of Attentional Templates Affects Dual-target Search

by Clinical Neuropsychologist | Wednesday, October 1, 2025 | Cognitive Neuropsychology

AbstractNeural activation of the target representation (template) facilitates attentional guidance, allowing humans to effectively perform visual search. However, visual search is not always very effective, especially when searching for multiple templates. The reduced...

Theta Stimulation Enhances Early Consolidation of Semantic Memory

by Clinical Neuropsychologist | Monday, September 1, 2025 | Cognitive Neuropsychology

AbstractThis study investigates the role of theta frequency transcranial alternating current stimulation (tACS) in enhancing the consolidation of newly acquired semantic knowledge. Although postencoding theta oscillatory power increase has been reported to benefit...

High-frequency Repetitive Transcranial Magnetic Stimulation over the Left Dorsolateral Prefrontal Cortex Can Improve Attentional Control Under Stress: Behavioral and Electrophysiological Evidence

by Clinical Neuropsychologist | Monday, September 1, 2025 | Cognitive Neuropsychology

AbstractPsychological stress impairs cognition, forcing attention toward stressor-related information. However, stress may reallocate limited cognitive resources in adaptive ways. How stress modulates the attentional control remains unclear. In this study, the...

Resting-state Alpha and Mu Rhythms Change Shape across Development But Lack Diagnostic Sensitivity for Attention-Deficit/Hyperactivity Disorder and Autism

by Clinical Neuropsychologist | Monday, September 1, 2025 | Cognitive Neuropsychology

AbstractIn the human brain, the alpha rhythm in occipital cortex and the mu rhythm in sensorimotor cortex are among the most prominent rhythms, with both rhythms functionally implicated in gating modality-specific information. Separation of these rhythms is nontrivial...

Estimating the Mean: Behavioral and Neural Correlates of Summary Representations for Time Intervals

by Clinical Neuropsychologist | Monday, September 1, 2025 | Cognitive Neuropsychology

AbstractOur behavior is guided by the statistical regularities in the environment. Prior research on temporal context effects has highlighted the dynamic processes through which humans adapt to the environment’s temporal regularities. Whereas earlier approaches...
