This study meta-analyzes 73 studies showing that short-term monocular deprivation in adults shifts ocular dominance toward the deprived eye, with effects lasting longer with extended deprivation.

Imagery priming of binocular rivalry is not a reliable metric of individual differences in the subjective vividness of visualisations.

This study investigates whether binocular rivalry priming can predict subjective visual imagery vividness, finding no strong correlation between the two.

The paper investigates how visual adaptation affects contrast sensitivity across meridians and finds stronger adaptation along the horizontal meridian, correlating with V1 cortical surface area.

Microsaccades track shifting but not necessarily maintaining covert visual-spatial attention

The paper shows that microsaccades track shifting covert visual-spatial attention but not maintaining it, depending on the stage of attentional deployment.
