Many factors influence identification accuracy.These include facial familiarity and distinctiveness, race, age and gender.There are also individual differences in face perception and recognition, and these may have a genetic foundation.Some individuals exhibit developmental prosopagnosia, or face blindness;while others possess "super-recognition" ability.These extremes may be symptomatic of the extremes of a normal continuum of face recognition ability.In recent research, police officers (n =21) who have identified hundreds of offenders from sometimes extremely poor quality CCTV footage completed a battery of cognitive tests.Their performance was compared with controls (n =100).The performance of some officers was exceptionally better than controls on some tests, particularly when naming highly degraded celebrity images, taken more than 10-years beforehand.Performance was highly correlated with a second unfamiliar face array test.However, face recognition performance was negatively correlated with a flowers recognition task.The applied and theoretical implications will be discussed in terms of the Face Space model of face recognition, and domain-specific brain modularity theories that propose faces are processed by dedicated cortical networks.
