Starting from the early 2010s, several studies have shown that a short period of monocular deprivation in adult volunteers transiently shifts ocular dominance in favour of the deprived eye. We compiled a meta-analysis of 73 such studies and found that the shift of ocular dominance was reliably observed, although with variable effect sizes mainly associated with the duration of deprivation and...
Although retinal illumination is the main determinant of pupil size, evidence indicates that extra-retinal factors, including attention and contextual information, also modulate the pupillary response. For example, stimuli that evoke the idea of brightness (e.g., pictures of the sun) induce pupillary constriction compared to control stimuli of matched luminance. Is conscious appraisal of these...
