This study will show you 40 cat faces. You have to decide whether you think that the cat are male or female - from looking at the face alone!
To run experiments we need to present people with stimuli - images, sounds and so on. For some planned experiments we need some photographs of people when they were around 20 and then later when they were around 60. Details of the photos needed and how to get in touch are given here.
