I Recognise You! But How Did I Do It? How local Chinese see faces?


 
ScienceDaily (Jan. 13, 2012)Are you someone who easily recognises everyone you've ever met? Or maybe you struggle, even with familiar faces? It is already known that we are better at recognising faces from our own race but researchers have only recently questioned how we assimilate the information we use to recognise people.

New research by the University of Nottingham Malaysia Campus has shown that when it comes to recognising people the Malaysian Chinese have adapted their facial recognition techniques to cope with living in a multicultural environment.

The study 'You Look Familiar: How Malaysian Chinese Recognise Faces' was led by Chrystalle B.Y. Tan, a PhD student at the University of Nottingham Malaysia Campus. The results have been published online in the scientific journal PLoS One, This research is the first PhD student publication for Nottingham's School of Psychology in Malaysia.

Chrystalle Tan said: "Our research has shown that Malaysian Chinese adopt a unique looking pattern which differed from both Westerners and Mainland Chinese, possibly due to the multicultural nature of the country."

The ability to recognise different faces may have social and evolutionary advantages. Human faces provide vital information about a person's identity and characteristics such as gender, age, health and attractiveness. Although we all have the same basic features we have our own distinguishing features and there is evidence that the brain has a specialised mental module dedicated to face processing.



Recognition techniques

Previous research by a group at Glasgow University in Scotland showed that Asians from mainland China use more holistic recognition techniques to recognise faces than Westerners.
  • Chinese focus on the centre of the face in the nose area
  • Westerners focus on a triangular area between the eyes and mouth
  • British born Chinese use both techniques fixating predominantly around either the eyes and mouth, or the nose
Chrystalle said: "The traditional view is that people recognise faces by looking in turn at each eye and then the mouth. This previous research showed us that some Asian groups actually focus on the centre of the face, in the nose area. While Westerners are learning what each separate part of the face looks like -- a strategy that could be useful in populations where hair and eye colour vary dramatically, mainland Chinese use a more global strategy, using information about how the features are arranged. Meanwhile British born Chinese use a mixture of both techniques suggesting an increased familiarity with other-race faces which enhances their recognition abilities."

Eye tracking technology

The study by the School of Psychology at the University of Nottingham Malaysia Campus set out to investigate whether exposure and familiarity with other cultures affects our recognition accuracy and eye movement strategies.

The team used specialised eye tracking technology to investigate the visual strategies used to recognise photographs of faces. They recruited 22 Malaysian Chinese student volunteers from across Nottingham's Malaysia campus. The results showed that Malaysian Chinese used a unique mixed strategy by focusing on the eyes and nose more than the mouth.

Chrystalle said: "We have shown that Malaysian Chinese adopt a unique looking pattern which differed from both Westerners and mainland Chinese. This combination of Eastern and Western looking patterns proved advantageous for Malaysian Chinese to accurately recognise Chinese and Caucasian faces."

The study was supervised by Dr Ian Stephen, an expert on face processing and Dr Elizabeth Sheppard, an expert in eye tracking. Dr Stephen said: "We think that people learn how to recognise faces from the faces that they encounter. Although Malaysia is an East Asian country its ethnic composition is highly diverse. The intermediate looking strategy that Malaysian Chinese use allows them to recognise Western faces just as well as Asians."

How local Chinese see faces?

A study shows that Malaysian Chinese have their own distinct way of identifying faces compared to Caucasians and those from mainland China.

NEW research by the University of Nottingham Malaysia Campus has shown that when it comes to recognising people, the Malaysian Chinese have adapted their facial recognition techniques to cope with living in a multicultural environment.

The study had established that we were already better at recognising faces from our own race. However, researchers had only recently questioned how we assimilated such information to recognise people.

Life’s an ocean of possibilities






WHEN I was young, I had always thought that everything was possible. Perhaps, many may feel that such (blind) optimism is a characteristic of a child, and come adulthood we grow out of it after experiencing first hand many downfalls.

I am an adult now, and although I may not agree that everything is possible (I can’t possibly grow wings now and fly to the moon, right?), I do still very much believe that many great things are definitely possible.

Born to a father who was a factory worker, with a Form 5 education and a housewife mother, whose highest education was Form 3, perhaps not much would have been expected of the child.

Living and growing up with two other siblings in Kampung Ujung Batu in Butterworth, a kampong now notorious for gangsterism and illegal drug activities, what could society expect of its residents?

Against all these odds, for inexplicable reasons and turn of circumstances, after performing well in my primary school studies, I ended up in a premier school, St. George’s Girls’ School (SGGS).

Travelling daily to school on board the ferry and taking the bus for the first two years, and then carpooling for the subsequent years was nothing less than a great learning curve as well as wholesome fun.

SGGS taught me the importance of wholesome education by providing not only academic pursuits, but also character and moral formation, teaching me respect for individuals irrespective of race or creed.

At this stage, my father had already stopped working due to a defective heart valve and a major open heart surgery that sapped his strength and affected his performance.



Mother now took up a job in a sardine factory to help contribute to the monthly income of the family.
Our family of five survived comfortably on RM1,600 a month.

Never did I feel the pinch of not having enough. Perhaps, my parents never allowed us to feel that way.

Much to the surprise of my parents and some of my teachers, I did well in the SPM and, eventually, STPM, which led me to the University of Malaya to pursue a degree in Biomedical Science.

There, again to my surprise, I graduated with a distinction, and won the award for best oral presenter for my final year research project.

That was two years ago. Right now, I am a tutor in my faculty and have been working on research projects.

Graduating with a CGPA of 3.77 provided me with the opportunity to pursue my PhD directly without having to complete my Masters.

I was blessed with the opportunity to pursue my PhD and work with a world-reknown researcher in the University of Sydney, Prof Dr Nicholas Hunt, whose research work is in the field of malaria, and who is also credited with the groundbreaking find of a new human enzyme.

It’s been two years since I started applying for scholarships. I’ve been to a number of interviews that puzzlingly found me and my research project not worth funding.

Yet, I believe that great things are still possible. Not because of who I am but because of who God is in our midst. After almost two years, various applications and countless email, I was finally offered a scholarship by the University of Malaya to pursue my PhD last March.

Has the journey been smooth since then? Don’t even think about it. My approval is still stuck with the Ministry of Higher Education, although I am supposed to report in Sydney in July.

Have I given up? Of course not. Do I feel like giving up? Sometimes, but rarely so. Will I have to rush through my preparations? Without a doubt. Do I wish that the system was more efficient and assisted the students better? Of course.

But none of this stops me from trying every day to move forward to the things I dream for.
Opportunities come, but never easily or smoothly. Good things worth fighting for, are worth waiting for. I see where I come from and I see where I am today.

In all of it, I see a never-ending string of surprises intricately entwined in the journey of my life. Where we come from does not determine where we will go. What we don’t have does not decide what we will end up with.

Life is an ocean of possibilities. It moves forward with the vehicle of faith.
