| The main study parameter is the ‘report errors’ participants produce in different luminance and crowding conditions. The ‘report error’ is described by the distance between the reported gap orientation and the presented target gap orientation. It can range between -180 to 180 degrees. This main parameter will be used to calculate the crowding magnitude and extent in different luminance conditions. | — |
