Imagine you lose sight of your friends (or parents) for a moment while you are out at the park. You glance around and then spot them in the distance. You easily pick them out from all the other people in the park and you correctly identify them. This process is called familiar face recognition. For most of us, this process seems easy and generally people are good at recognising familiar faces. However, a few people really struggle to recognise the people around them. Other people are “super-recognisers” who have an extraordinary ability to recognise faces very accurately. How good are you at recognising faces? In this article, we outline why some people are better (or worse) at recognising faces and explore the possible importance of brain differences, mental processes, and personality in this ability.
Most of us can recognise the people around us, our friends, family, and teachers. By the time we are adults, most of us can accurately recognise hundreds of different people. This ability is shaped by our social environment. For example, people generally find it easier to recognise faces from the same racial and age groups as themselves. Why is face recognition important? It helps us to act the right way in social situations, for example sharing a joke with a friend and paying attention to the teacher, rather than the other way around! Recent research has focused on individual differences in face-recognition ability. Some people are particularly poor at recognising faces while other people, nicknamed super-recognisers, can very accurately remember and recognise faces. Super-recognisers have even helped the police to identify suspects involved in crimes!1
Most of us are between these extremes—we are not really bad at recognising faces, but we are not super good either. Instead, we are within the middle part of the normal range of performance (Figure 1). For example, in a study in which participants were asked if two pictures show the same person or different people, performance ranged from 62 to 100% correct across individual observers . Why are some people better at recognising faces?
Brain differences between individuals are one possible reason for differences in the ability to recognise faces. Maybe people who are good at recognising faces have brains that are bigger, more connected, or somehow working better than the brains of people who are not so good at recognising faces? Several brain areas important for face recognition are found in the temporal lobes, which are located at the sides of the brain, above the ears (Figure 2). We know that people with damage to these brain areas may have a disorder called prosopagnosia. Prosopagnosia has been called “face blindness” and it is characterised by difficulty recognising familiar faces.
Do people who are good at recognising faces have face-recognition areas in their brains that are more developed than those of other people? The short answer is that we are not really sure. Some work has suggested that a higher level of activation in these brain areas is related to better face recognition . Other researchers have found that people with very poor face-recognition abilities may have fewer connexions between the various face-related areas of the brain . Overall, more research is needed to determine whether differences in brain activation and connectivity play a role in how good we are at recognising faces.
A second possible reason for individual differences in face recognition is that this ability is related to factors like intelligence or memory—these are both types of cognitive processing. Cognitive processing means the mental processes (things that go on in our heads) that are involved in gaining knowledge and understanding. Maybe people who are more intelligent are better at recognising faces? Research on this topic asks volunteers to take part in an intelligence test and a face-recognition task. Results from these tasks are then compared and, generally, no strong relationship is found. This means that it is not the case that the cleverest people are always the best at recognising faces.
There does seem to be a relationship between face recognition and visual processing ability, which is the brain’s ability to understand and remember things that we see. For example, research found that face-recognition performance was related to visual short-term memory . You might have taken part in a visual memory game yourself. You see a group of objects—for example, pictures of foods, clothes, instruments, animals, plants, vehicles, or other things. These objects are shown briefly, usually only for a few seconds, and then covered up. Your task is to remember as many of the objects as possible (Figure 3). The number you remember is a measure of your visual short-term memory. Researchers found that the results of this kind of memory test were related to face-recognition ability—as one ability increased, so did the other.
Personality and Social Interaction
It is also possible that how good people are at recognising faces is linked to their personalities or levels of social interaction. Perhaps people who are more interested in meeting and talking with other people are more practised at recognising faces and are better at recognising them. Alternatively, people who are not good at recognising faces may avoid people so that they are not embarrassed by their inability to recognise familiar faces. What do you think?
Research has shown that people who are better at thinking about and sharing the emotions of others—a trait called empathy—are better at recognising faces. Volunteers were asked to answer a series of questions to measure their empathy and they also participated in a face-recognition task. Results showed that the “high empathy” group performed better on the face-recognition task compared with the “low empathy” group . Research has also shown that people who are worried and anxious in social situations are worse at recognising faces compared with more confident people . People who are more outgoing and sociable (extraverted) are better at recognising faces than people who are more introverted . There is also some evidence that a tendency toward negative feelings has a negative influence on face recognition. What kind of person are you? Do you like interacting with the people around you, or are you more reserved?
Can Face-Recognition Ability Change?
Can the ability to recognise faces change with time? Are there things we can do to get better at recognising faces? It is thought that the ability to accurately recognise faces improves with age, starting at about 5 years old until adulthood, with a dip possible during early adolescence. There is also a decrease in face-recognition ability from about age 30 onwards, as we age.
There are many skills we can learn by practising them—is face recognition one of these skills? Researchers are still not sure. It may be that the more people we meet, the better we are at face recognition. However, simply increasing contact with faces does not necessarily improve performance. For example, one study showed that nursery workers and school teachers, who see a lot of children’s faces, were no better at identifying faces than were people with little experience with children .
People with prosopagnosia often say that they struggle to recognise their classmates and form friendships—can anything be done to help them? Some people with prosopagnosia use coping strategies (tricks to help them recognise people), including details of people’s hairstyles or clothing. But training people to be better at face recognition is difficult, and training prosopagnosics does not usually produce any lasting improvement in face recognition. We also know that many passport control officers and police officers find it challenging to recognise faces, and training does not improve their recognition ability.
We are surrounded by people, and recognising their faces allows us to form friendships, interact appropriately, and work or play together. However, we are not all equally good at recognising faces. Individual differences in the ability to recognise faces might be related to differences in our brains, for example, how much some brain areas are activated when we see faces and how well certain brain areas work together. These differences might also be related to our visual processing abilities, or aspects of our personalities, such as how outgoing and sociable we are. Understanding these individual differences is important. Some jobs, such as passport officers at airports and borders or facial examiners working for the police require a high level of face recognition, and it does not seem that this ability can be easily improved with practise. It might be better to select people who are naturally good at recognising faces for these jobs. Maybe this could be you!
Normal Range of Performance: ↑ The range of scores obtained by people on tests of a particular task or skill (in our case, face recognition).
Temporal Lobes: ↑ One of the four main regions of the brain. There is a temporal lobe on each side of the brain, located close to the ears. This area of the brain is involved in visual memory, language understanding and emotion processing.
Prosopagnosia: ↑ A neurological condition that is characterised by the inability to recognise familiar faces.
Cognitive Processing: ↑ The mental processes (things that go on in our heads) that are involved in gaining knowledge and understanding things. These include perception, encoding, and memory.
Visual Processing Ability: ↑ The brain’s ability to use and interpret information from things we see in the world around us.
Empathy: ↑ The ability to understand and share the feelings of other people.
