If you think that you can judge by examining someone’s facial expressions if he has just hit the jackpot in the lottery or lost everything in the stock market — think again. Researchers at the Hebrew University of Jerusalem and at New York University and Princeton…

FUTUREJAM: Judging facial expression not enough to determine emotion

You move, he moves. You smile, he smiles. You get angry, he gets angry. “He” is the avator you chose. Faceshift, from EPFL’s Computer Graphics and Geometry Laboratory, now offers a software program that could save time for the designers of animation or video games. Thibaut Weise, founder of the start-up, smiles and nods. On the screen his avatar, a fantasy creature, directly reproduces his gestures. This system could enhance the future of video games or even make video chats more fun. One tool required: a camera that has motion and depth sensors in the style of Microsoft Kinect or Asus Xtion, well known to gamers. During its first use, the software needs only ten minutes to recognize the user’s face. The user reproduces several basic expressions requested by the program: smile, raise eyebrows, etc. “The more movement is incorporated into the program’s 50 positions, the more realistic are the results,” explains Thibaut Weise, creator of the start-up currently based at the Technopark in Zurich. Then you can get into the skin of your character and animate by moving yourself. “It’s almost like leaving your body to enter that of your avatar,” jokes the young entrepreneur.

Many animal species transmit information via chemical signals, but the extent to which these chemosignals play a role in human communication is unclear. In a new study published in Psychological Science, a journal of the Association for Psychological Science, researcher Gün Semin and colleagues from Utrecht University in the Netherlands investigate whether we humans might actually be able to communicate our emotional states to each other through chemical signals. Existing research suggests that emotional expressions are multi-taskers, serving more than one function. Fear signals, for example, not only help to warn others about environmental danger, they are also associated with behaviors that confer a survival advantage through sensory acquisition. Research has shown that taking on a fearful expression (i.e., opening the eyes) leads us to breathe in more through our noses, enhances our perception, and accelerates our eye movements so that we can spot potentially dangerous targets more quickly. Disgust signals, on the other hand, warn others to avoid potentially noxious chemicals and are associated with sensory rejection, causing us to lower our eyebrows and wrinkle our noses. Semin and colleagues wanted to build on this research to examine the role of chemosignals in social communication. They hypothesized that chemicals in bodily secretions, such as sweat, would activate similar processes in both the sender and receiver, establishing an emotional synchrony of sorts. Specifically, people who inhaled chemosignals associated with fear would themselves make a fear expression and show signs of sensory acquisition, while people who inhaled chemosignals associated with disgust would make an expression of disgust and show signs of sensory rejection.

Evolution has tailored the human eye for detecting red, green, blue and yellow in a person’s skin, which reveals areas where that person’s blood is oxygenated, deoxygenated, pooled below the surface or drained. We subconsciously read these skin color cues to perceive each other’s emotions and states of health. Rosy cheeks can suggest good health, for example, while a yellowish hue hints at fear.

Now, researchers have created new glasses, called O2Amps, which they say amplify the wearer’s perception of blood physiology, augmenting millions of years of eye evolution.

Do Dogs Feel Guilty?

I walked into the house, and he was acting strange. I could tell he had done something wrong,” she told me. I pressed for further details. “His head was down, and he wasn’t making eye contact,” she explained. “Then, I found it. Under the bed.” She had spent weeks training her dog, Henry, not to crap on the carpet. And there it was, under her bed. Evidence that he had transgressed. “He knew he had misbehaved, that’s why he was acting so guilty,” my friend insisted, sure that her dog knew that he had violated her rule. Seventy-four percent of dog owners believe that their dogs experience guilt. One owner described her reasoning as follows: “I behave in a particular way when I feel guilty; my dog behaves in a similar way in equivalent circumstances; I know intuitively that my behavior is motivated by guilt; therefore the behavior I see in my dog is also accompanied by feelings of guilt.” Almost sixty percent of dog owners claim that their dogs’ guilty behavior leads them to scold their dog less.

Jaak Panksepp has taken on many unusual roles in his storied career, but none so memorable as rat tickler: He learned how to stimulate the animals to elicit high-frequency chirps that he identified as laughter. Panksepp’s interspecies game-playing garnered amused media coverage, but the news also stirred up old controversies about human and animal emotions. Since the 1960s, first at Bowling Green State University and later at Washington State University, Panksepp has charted seven networks of emotion in the brain: SEEKING, RAGE, FEAR, LUST, CARE, PANIC/GRIEF, and PLAY. He spells them in all caps because they are so fundamental, he says, that they have similar functions across species, from people to cats to, yes, rats.

“Please don’t put me in the closet,” cries the robot. Last week, we wrote about a study that looked at whether humans attribute moral accountability and emotions to robots. This week, we’ve got a study from the same group, the Human Interaction With Nature and Technological Systems Lab (HINTS) at the University of Washington, that takes a look at what kind of relationships children are likely to form with social robot platforms, and it involves forcing their new robot friend into a dark, lonely closet. The 90 children in this study were separated into three groups by age: 9 year olds, 12 year olds, and 15 year olds, with an equal mix of boys and girls. As with the previous study, the robot involved in the research was Robovie, a vaguely humanoid robot that was secretly teleoperated to give it the appearance1 of a sophisticated (but not necessarily unrealistic) level of autonomy and interactivity.
