There is a link between facial recognition and extrovert and introverted personality

While there is a person called '

Super Recognizer ' who has more ability than AI face recognition technology, it is very difficult for a person with 'Developmental Prosopagnosia ' to recognize the face of another person. Most people's facial recognition abilities fall between these two extremes, distinguishing hundreds of faces, but still vary from person to person. This difference in ability may be due to the difference in personality.

Introvert? You may just be bad at recognizing faces

It is not clear what causes the difference in face recognition ability, but 'difference in brain processing and structure', 'relationship with cognitive ability such as memory and visual processing', 'personality and social'・ It is thought that the reason is 'reflection of emotional function'.

In 2010, experiments were conducted to 'show subjects multiple faces and identify their identities' and 'then mix new faces to identify whether they have seen or added faces'. It was. At this time, the subjects who self-identified as having high emotional transfer ability had significantly better face recognition ability than the subjects who self-identified as having low emotional transfer ability. At the same time, those who reported significantly lower levels of anxiety were also found to have higher facial recognition abilities.

It has been found that the relationship between 'anxiety' and facial recognition ability is more pronounced in women. In particular, it has been suggested that it is related to social anxiety, but situational anxiety is also considered to be a factor. One example is when a person who witnesses an incident in a stressful situation cannot recognize the suspect's face.

Karen Lander and colleagues at the University of Manchester have gathered 100 people of different tendencies to investigate the relationship between human extroversion and facial recognition. Then, we conducted a face recognition experiment in which the subjects looked at the faces of celebrities and entered information such as names, and a face matching experiment in which they looked at two faces and guessed whether they were the same person or different people. Then, although there was no relationship between extroversion and the results of the face matching experiment, there was a positive relationship between the results of the extroversion and the face recognition experiment.

This, combined with previous studies, suggests that there is some link between extroversion and facial recognition ability.

However, 'extroverts have better ability to read social information than introverts and tend to actively participate in social activities (there are many opportunities to meet other people), so face recognition ability. Although it is speculated that 'it should be higher', it is still unclear whether it 'has gained ability because of its personality' or 'whether it has become such a personality because of its ability'. According to Lander, both extroversion and facial recognition may be associated with other factors that are not yet known.
