Experiment Instructions
In this experiment, you will judge whether there is any upside-down (inverted) face in each picture.
Your goal is to respond as quickly and as accurately as possible.
If any face is upside-down, respond YES. If all faces are upright, respond NO.
If there is only one face in the picture, judge whether that face is upside-down or not.
Experiment Instructions (continued)
In each trial, you will first see a fixation cross (see example below). Please keep your eyes on the cross.
Then, you will see the picture briefly.
Make your judgment immediately when the picture appears: decide whether there is any upside-down face in the picture.
Press F = Yes Press J = No
Experiment Instructions (continued)
