The purpose of this task is to measure individual information processing abilities with regards to local and global perceptual stimuli. In this task, participants are presented a 60-trial global block and a 60-trial local block of the Navon task in a randomised order. For each trial, participants have to identify the shape of the figure (either overall figure or tiny figure) presented as fast as they can.

This task measures how fast and accurate participants are in their global processing of stimuli figures.
This task comprises of 1 practice trial and 1 block of 60 trials. Participants are asked to identify the global figure (i.e. the overall shape) presented on the screen. 4 different shapes are each presented 15 times within the trial block in a randomized order. They are as follows:
Consistent shapes:
Inconsistent shapes:
