This study investigates how the human brain encodes selected and non-selected visual targets during voluntary selection, finding that selected targets are encoded along an additional spatially selective axis.

The paper introduces a method to track covert attention using phase-modulated RIFT-EEG with multiple tags, enabling fine-resolution spatial and temporal attention mapping.

The paper shows that anticipating stimulus relevance enhances visual processing to support memory-guided selection.

The paper investigates whether visual attention travels or teleports during covert shifts, finding no evidence of intermediate processing enhancement.

This study shows that human saccade selection follows cost-benefit computations consistent with neuroeconomic decision-making, revealing dissociable roles for effort-costs and rewards.

This paper introduces a luminance-corrected pupillometry method to improve effort tracking in dynamic environments, showing it enhances discriminability and classification performance when combined with other measures.

The paper investigates how bottom-up saliency and top-down goals compete in early visual cortex using EEG and RIFT, showing dynamic suppression of distractors over time.

This study shows that expectations about search difficulty modulate attention through gain-based signal enhancement rather than changes in spatial scope.

The paper measures proactive and reactive attentional markers in an EEG-eyetracking task and shows they are independent processes, with gaze bias predicting behavior.

This study investigates neural markers of auditory working memory load using EEG, finding that alpha-band oscillations, not lateralized responses like CDA, reflect dynamic coding of load.

This study uses EEG and decoding techniques to show that population-level neural activity dissociates preparatory overt from covert attention, revealing an additional spatially selective process in overt attention.

This study demonstrates that covert attention can be reliably measured using RIFT on a 360Hz consumer monitor, expanding accessibility for cognitive neuroscience research.

The paper investigates whether reappearing sensory input can guide the prioritization of non-reappearing items in visual working memory, finding that matching location and orientation enhances prioritization.

This study shows that visual working memory can be flexibly adjusted based on task demands, with increased effort during maintenance when higher precision is required, though this effort sometimes exceeds performance benefits.

The paper shows that saccade selection is driven by the effort (cost) associated with each saccade, with less costly directions being preferred even in natural scenes and under increased cognitive demand.

The paper investigates the neural mechanisms of external and internal attentional selection using EEG and RIFT, finding that only external attention enhances sensory processing.

This paper uses SSVEPs to track dynamic spatial attention allocation during visual working memory tasks, showing attention shifts before probe comparisons.

The paper re-analyzes an experiment showing that gaze biases during a memory task reflect attention to task-relevant stimulus endpoints rather than memorized orientations.

This paper implements and validates the first RIFT-EEG setup, showing that RIFT can evoke measurable oscillatory responses in EEG comparable to MEG.

The paper shows that memorized stimuli have stronger neural representations than perceived ones in a change-detection task, contradicting subjective experience.

The paper shows that attention to visual working memory representations exhibits theta-rhythmic competition, similar to attention to external objects.

The paper investigates how visual transients affect adaptation to interocular conflict in binocular rivalry, finding that transient frequency, not conflict degree, drives mixed percept incidence.

The paper investigates how exogenous attentional cues modulate the pupillary light response and whether this modulation affects detection performance for threshold stimuli.

The paper presents norm scores for cancellation task performance in a large sample of healthy adults, identifying cognitive profiles and noting that poor search organisation is common in healthy individuals.
