UNSW Sydney psychologists have developed a new facial identification capability test that will help find facial recognition experts for various police and government agencies, including contract tracking.

The Glasgow Face Matching Test 2 [GFMT2] is aimed at people with high-performance facial recognition known as superrecognizers, who have an extraordinary ability to memorize and remember .

The type of professional roles that involve face identification and that could benefit from they include visa processors, passport issuers, border control officers, police officers, contract plotters, as well as private industry security personnel.

“Being able to recognize the faces of friends and family is a skill that most of us take for granted,” says Dr. David White, a member of Scientia, of the UNSW Science School of Psychology.

“But comparing images of unknown faces and deciding whether to show the same person is a task that most of our participants find challenging, even passport officers with many years of experience in the task.

“An important finding in our field in recent years has been that some people are much better than others at identifying faces from photographs.

“This is a vision that has changed the way we hire staff, for example passports and police officers.”

The principal investigator at the UNSW Sydney Facial Investigation Laboratory states that the GFMT2 test is valuable in identifying super-recognitions that have been used by the London Metropolitan Police Service in , and famous for the alleged poisoning of former Russian spies in Salisbury.

The GFMT2 test, an expanded version of the original Glasgow Face Matching Test that was launched ten years ago, has been published in the journal Behavior Research Methods.

It was developed in collaboration with York University and the Australian Passport Office.

Dr. White says the current test is to match faces between changes that make it difficult to identify faces in real-world tasks.

“For example, when CCTV is matched to cup images, there may be changes in head angle, camera subject distance, image quality, and expression,” he says.

It also includes tests aimed at people with low-performance facial recognition, such as people with prosopagnosis or “facial blindness.”

The improved test comes when the federal government has been considering the possibility introduction of a centralized database that would house photos collected by various state and federal agencies, including police charge and passport photos, immigration documents, and driver’s licenses.

One criticism of the database proposal has been that facial recognition software is prone large amounts of errors this has led to unjustified arrests.

“This technology shows close matches to a suspect on the screen, and therefore human error at this stage can have serious implications,” says Dr. White.

But the super-recognitions revealed by GFMT2 can be used to review identity matches made by facial recognition software and help prevent false identity matches, he says.

“This new test is especially important in the current era, where facial recognition software is increasingly used as a search engine in police investigation and security scenarios,” he says.

“It’s much more promising than training people to have these facial identification skills.

“Our recent work suggests that current vocational training courses in it does not improve people’s performance. “

The test can be used in several countries, including Australia, New Zealand, the United Kingdom and Canada.

“We’ve learned a lot from a decade of collaborating with professional groups,” says Dr. Rob Jenkins of York University School of Psychology.

“The new test meets your requirements.”

The test also allows comparing before and after comparisons the impact of training and other interventions.

“The scientific understanding of face perception has made huge strides in the last ten years,” says Professor Mike Burton of York University School of Psychology.

“This update gave us the opportunity to build new knowledge.”

All tests are available free for scientific use.


The study finds that masks make little difference in facial identification
