Neural Encoding Geometry of Human Voluntary Visual Selection

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.

Anticipated Relevance Prepares Visual Processing for Efficient Memory-Guided Selection

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

Attentional selection is a neuroeconomic decision

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

Luminance-corrected Pupillometry for Reliable Effort-tracking in Dynamic Environments

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.

Pupil size reveals the perceptual quality and effortless nature of synesthesia

This study uses pupillometry to objectively measure synesthetic color phenomenology, showing that pupil size reflects brightness and effortlessness of synesthetic experiences compared to controls.

Population-Level Activity Dissociates Preparatory Overt from Covert Attention

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.

Reappearing Sensory Input Guides Visual Working Memory Prioritization

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.

Effort Drives Saccade Selection

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.

SSVEPs reveal dynamic (re-)allocation of spatial attention during maintenance and utilization of visual working memory

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