Description: In this experiment, we will test to see whether expert fingerprint examiners have better visual search abilities compared to novices with a class of stimuli they are familiar with. We will also test whether their superior performance disappears when the structural regularities of the stimuli are removed, or if asked to spot non-diagnostic information. We have conceptualised a fingerprint-like visual search task much like the spot-the-difference tasks you might see in a newspaper to assess how well people can find points of disagreement between prints. Participants will be presented with two fingerprint images side-by-side that are identical but for one fragment that has been replaced with alternative ridge information. They will be asked to spot this difference.
