When visual attention is divided in the flash-lag effect

This study investigates how divided visual attention affects the flash-lag effect, finding that divided attention increases the illusion's magnitude but not its variability.

Simultaneous Modeling of Reaction Times and Brain Dynamics in a Spatial Cuing Task

This study evaluates bDCM for modeling reaction times and brain dynamics in a spatial cuing task, finding it performs well compared to classical DCM and Rescorla-Wagner model.

Motion extrapolation in the flash-lag effect depends on perceived, rather than physical speed

The paper investigates whether the flash-lag effect (FLE) depends on perceived or physical speed by manipulating perceived speed through texture and contrast, finding that FLE magnitude correlates with perceived speed.

Statistical learning of frequent distractor locations in visual search involves regional signal suppression in early visual cortex

The paper investigates how visual cortex suppresses distractors at frequent locations through fMRI and finds differential neural mechanisms based on distractor dimension.

Attentional reorientation along the meridians of the visual field: are there different neural mechanisms at play?

The paper investigates whether attentional reorientation along horizontal and vertical visual field meridians involves different neural mechanisms using fMRI and behavioral data.
