This is a follow-up on “Peripheral visual detail”. Here, we continue to investigate whether saccades improve peripheral visual perception. Participants will perform again a peripheral visual discrimination task on object stimuli before and after an inspection phase. In this version of the experiment, however, the tasks between peripheral phases and the inspection phase are switched. In the peripheral phases, participants categorise objects as electronic or non-electronic and in the inspection phase they perform the tilt discrimination task. The idea is that object categorisation benefits more from inspecting, i.e. learning something about, the object and therefore this new setup is expected to lead to larger difference between inspection conditions than the previous setup of “peripheral visual detail”. In addition, here we have one more inspection condition in which the object is presented only peripherally. We expect the same pattern of results which we expected in the previous version of the experiment and in the additional peripheral-only inspection condition we expect the least (compared to the other inspection conditions) improvement in discrimination performance from peripheral phase I to peripheral phase II. This peripheral condition serves as further control in contrast to the foveal condition to find out whether inspecting the object has some influence at all on peripheral object perception. |
