Body Language GamePlay

Marco Gillies of GoldSmith college was spurred into launching a new computer gaming project that works with actors because he thinks that “games shouldn’t be designed by programming experts, but by experts in movement.”

Programming companies have already successfully aimed at creating gaming characters with realistic-looking movements.  However, Gillies and his colleagues are developing characters that can recognize subtle movements and express them in a very natural way.

This system will hopefully be the first truly interactive gaming system of its kind with the algorithm’s ability to react to social behaviors and subtle body movements.

 ”Writing software to recognise complex and subtle movements like human body language is notoriously difficult.  We are taking a different approach, which allows people to design movement interfaces directly by moving,” Gillies told Wired.co.uk.

The project works with actors attached to motion sensors that are tracked by Kinect cameras to create natural movements via a machine learning algorithm program that tracks their movements.

Gillies goes on to comment that, “Actors understand movement implicitly in their bodies, they understand movement by moving.  It would be almost impossible to turn that kind of implicit understanding into rules that we can explicitly program into some software.”

After testing their system using non-thespian gamers, they found that within three hours the subjects had begun designing simple games based on their body movements.

Mapping Culture

 Psychology Today reports on the variance of emotional landscapes in divergent countries.

The article is taken from a first hand experience and focuses on the difference in “anger” between varying cultures.

The writer was trying to answer for himself the question, “Is anger an innate human emotion, an evolutionarily hardwired part of our behavioral repertoire? Or is anger a subroutine of our cultural programming, acquired without awareness?”

So what were his findings?

Initially he found, The Expression of Emotion in Man and Animals,  written by Charles Darwin in 1872.  From that book he learned that anger is universal among humans and has its precursors in the expressions of primates.

“Under moderate anger the action of the heart is a little increased, the colour heightened, and the eyes become bright,” he wrote. “The respiration is likewise a little hurried; and as all muscles for this function act in association, the wings of the nostrils are somewhat raised to allow of a free indraught of air.”

The physiological responses of anger are increased heart rate, blood pressure, respiration, and blood flow to the limbs.  Angry people, whether in Canada or Tokyo, lower their brows, glare intensely with their eyes, and tighten their lips.

So, we now know that the physical experience of anger is the same across cultures but that leaves the more pertinent question, “why different cultures have different cultural triggers when expressing  anger?”  Well, the answer lies in the divergent values between cultures. 

It was this question that led him to Dr. David Matsumoto and his 2008 study, which examined the relationship between emotional expression and cultural values.  More than 5,000 people in 32 countries were surveyed in this study.

Anger is biologically hardwired yet culturally variable.  It is a vestige of our evolutionary past, yet also part of our cultural present.  This is why understanding divergent cultures is so important in our global society.

Matsumoto and his colleagues found that, in individualistic societies such as the United States personal goals and self-sufficiency are highly valued; therefore, making new acquaintances is seen as a good thing.  Individualists tend to control their anger when interacting with people outside their immediate circle but express anger fully toward close friends and relatives.

In collectivistic cultures such as Japan relationships and group goals are highly valued.  Harmonious relationships with the in-group are far more important than networking with strangers, so people strive to exercise emotional control within their close social circle.

Using Emotional Cues to Predict Acts of Terror or Political Aggression

New research entitled “Emotions expressed in speeches by leaders of ideologically motivated groups predict aggression” was recently published in the journal of Behavioral Sciences of Terrorism and Political Aggression.

The research suggests that when leaders use rousing speeches to evoke powerful emotions, those emotions may predict when a group will commit an act of violence or terrorism.

Dr. David Matsumoto, along with Drs. Hyisung Hwang and Mark G. Frank analysed speeches delivered by government and found that activist and terrorist leaders’ expressions of anger, contempt and disgust spiked immediately before their group committed an act of violence.

“When leaders express a combination of anger, contempt and disgust in their speeches, it seems to be instrumental in inciting a group to act violently”

As part of a five-year project funded by the U.S. Department of Defense’s Minerva Initiative, Matsumoto and colleagues studied the transcripts of speeches delivered by the leaders of ideologically motivated groups over the past 100 years. The analysis included such speeches as Osama bin Laden’s remarks leading up to the bombings of embassies in Kenya and Tanzania.

The researchers analyzed the pattern of emotions conveyed when leaders spoke about their rival group and examined speeches given at three points in time before a specific act of aggression. They compared the results with the content of speeches delivered by leaders whose groups engaged in nonviolent acts of resistance such as rallies and protests.

Among leaders of groups that committed aggressive acts, there was a significant increase in expressions of anger, contempt and disgust from 3 to 6 months prior to the group committing an act of violence.

For nonviolent groups, expressions of anger, contempt and disgust decreased from 3 to 6 months prior to the group staging an act of peaceful resistance.

Matsumoto says the findings suggest a leader’s emotional tone may cause the rest of the group to share those emotions, which then motivates the group to take part in violent actions.

“For groups that committed acts of violence, there seemed to be this saturation of anger, contempt and disgust. That combination seems to be a recipe for hatred that leads to violence,” Matsumoto said.

Anger, contempt and disgust may be particularly important drivers of violent behavior because they are often expressed in response to moral violations, says Matsumoto, and when an individual feels these emotions about a person or group, they often feel that their opponent is unchangeable and inherently bad.

“Understanding the preceding factors that lead to terrorist attacks and violent events may help predict these incidents or prevent them occurring in the first place…studying the emotions expressed by leaders is just one piece of the puzzle but it could be a helpful predictor of terrorist attacks.”

This study was one of the first seven projects funded by the U.S. Department of Defense Minerva Initiative. The Initiative was established in 2008 to fund social science research on areas of strategic importance to U.S. national security policy.
