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 information that is non-diagnostic. We have conceptualised a fingerprint-like visual search task much like a Where's Wally puzzle that assesses how well participants can find points of correspondence (the find-the-fragment task). Participants will be asked to find a small fragment of print information (presented on the left) within a larger fingerprint image (presented on the right) as quickly as they can.

Rationale Visual skills like identifying, classifying, and matching objects enable humans to navigate a world in which they continually encounter new stimuli. With practice, however, these general skills allow people to ...
