Data set for the study "The illusory perception of occluded space as empty depends on the occluded area"

The data set in this collection belongs to a scientific study investigating the illusion of absence. In this illusion, the space behind an occluder can be perceived as being empty. Data for this on-screen experiment was collected in the laboratory. Participants first saw an occluded scene and then a scene without the occluder, revealing what was hidden behind the occluder. The data set contains behavioural rating responses probing participants' perception of occluded space in two different presentation modes, presenting occluder and scene stimuli either sequentially or simultaneously.
