Culture and Body Posture

While research into cross-cultural non-verbal communication often focuses on facial expressions, body posture is also an important consideration. This may seem intuitive, as we all have experienced the role that body posture has in communicating emotions, but it has been neglected in most research, at the expense of its valuable potential for effectively reading people.

However, in a pair of studies, Dr. David Matsumoto sought to examine how body posture serves as a different non-verbal cue for people from American or Japanese cultures. While both of these studies date back to the 1980s, the evergreen and often neglected nature of this research merits consideration.

The first of these papers, coauthored with Dr. Tsutomu Kudoh, sought to test conventional wisdom about the role of posture in social situations against the possibility that these were limited only to Western culture. Past research had emphasized the immediacy of a reaction and the level of relaxation shown as the main predictors for how those postures would be understood.

In order to test these theories, Drs. Matsumoto and Kudoh recruited a large sample of Japanese subjects and asked them to develop a list of postures that they had encountered in real life. This resulted in a list of 40 postures which were then rated based on 16 criteria that included confident, respectful, friendly, or calm.

The participants were then instructed to imagine individuals they knew showcasing each of these postures and to rank them based on the aforementioned criteria. This allowed the researchers to assess the role that particular hierarchical roles may have in shaping these evaluations.

In fact, they found that their Japanese participants did evaluate posture in a significantly different way than Western-centric research had found. While Westerners emphasized like or dislike cues, these participants relied on cues rooted in status and power.

In another study with Dr. Kudoh, the researchers further examined the role of cultural norms in interpreting the emotions behind different postures. Given the conclusions of the previous paper, they emphasized that while the United States fosters an individualist culture, Japanese society is more characterized by status.

This paper gathered both American and Japanese students and asked each of these participants to rate the same postures with the same rubric from the last study. Interestingly, none of these postures were unknown to Americans, even though the list was developed by individuals from Japan.

Again, they found that the role of status differed dramatically between cultural groups, as Drs. Matsumoto and Kudoh found that considerations of status impacted social judgments of internal states and interpersonal interactions. They also found considerable variance between evaluations of different attitudes, such as pleasure and dominance.

Not only do these results help expand our understanding of cross-cultural behavior, but they also serve as a caution to avoid expectations that members of other cultures behave in the same way as do members of our own. This has crucial ramifications in attempting to read people, as we explicate in our cross-cultural communication workshops!

Anomalies and Deception Detection

While reading people can help in better communicating, it can also help in determining if somebody is lying to you. It was for this purpose that Humintell’s Dr. David Matsumoto and Dr. Hyi Sung Hwang worked with the Federal Bureau of Investigations to develop a rubric for how to effectively tell if you are being lied to.

Here, they focus on a series of tell-tale indicators, or behavioral anomalies, that give clues into the emotion or motivation of an individual. Law enforcement officials use these to verify statements or attempt to predict possible acts of aggression. While the subtlety of such indicators makes them difficult to detect, it also means that the interviewee does not necessarily know when they have exposed themselves.

One type of indicator consists of verbal cues. For instance, lies tend to omit details, use fewer words, and lack clear or defined structures. This is complicated however, as sometimes detailed descriptions of fictitious accounts are also markers of a lie. They offer an example of when an interviewee gives subtle details about a situation that, according to them, didn’t occur.

Another crucial type of indicator rests in purely non-verbal behavior. These often include excessive blinking, certain gestures, and fleeting microexpressions.  For example, when an interviewee is trying to conceal fear, their eyes might flash suddenly, revealing the white above the iris.

While we distinguish these two types, they are deeply interwoven, and a successful interviewer must keep both considerations in mind.

It is also important to expand on the term “anomaly.” While many people think that lying behavior is just universally evident, this is not always the case. Instead, a skilled interviewer must try to learn as much as they can about the person’s underlying personality. It is when people notably deviate from their baseline behavior that deception indicators are most apparent.

We also have to clarify that many so-called experts in deception detection emphasize indicators that have not been supported by empirical evidence. These often focus on eye contact, arguing that a failure to look an interviewer straight in the eye is a sign of deception. Numerous studies have disproven this persistent claim, so it is important not to let this sway your assessments.

While we would love to just list out everything to look for, these indicators are often either incredibly subtle or context-dependent.  After working closely with law enforcement to train them in these detection techniques, however, Dr. Matsumoto reported a dramatic increase in accuracy, from 10 to 25 percent!

Thankfully, these techniques are not limited to high-level law enforcement. While Humintell is proud to work with all sorts of agencies, we are also thrilled to work with people like you. We offer both a comprehensive class in evaluating truthfulness and a course in predicting possible signs of aggression that can help translate these ideas into making you the best people reader and deception detector possible.

Cultural Gestures and Verbal Cues

Many gestures may be universal, but are associated verbal cues translatable?

Last week’s Olympics blog discussed the universal gesture of triumph and touched on Humintell’s research into the universal nature of many gestures. However, just knowing that many gestures are universal is not enough to effectively read people. Instead, it is important to connect them to verbal messages.

This is exactly what Humintell’s Dr. David Matsumoto and Dr. Hyi Sung Hwang attempted to do in a 2013 study. This research catalogued various gestures, including both culturally similar ones as well as gestures that vary drastically between cultures.

They asked participants from all over the world to list out gestures based on a comprehensive list of possible verbal messages. These gestures were then shown to participants from the same region in order to maintain validity in the experiment. This process allowed Drs. Matsumoto and Hwang to determine which gestures were recognizable as the verbal cue in question.

Interestingly, they found that universal and varying gestures tended to convey categorically different emotions. While many culturally-specific gestures had complex associated messages, universal gestures tended to convey pretty elemental or basic emotions.

Still, they did notice differences. Some verbal messages, such as an insulting one, occurred in every culture but with different associated gestures. Other gestures occurred universally but with different meanings, including the “A-Ok” symbol in Western cultures which conveyed a variety of meanings, including a reference to “money.”

Finally, there were some gestures which were culturally specific and who’s verbal message existed nowhere else. For instance, the gesture for “apology” only occurred in South Asia, and the signal for “hunger” was not present outside of East Asia. No other regions used these gestures or used gestures to convey these concepts.

This sort of research is critically important for those of us who want to better read people. Many gestures convey verbal messages, clarify speech, or amplify certain meanings, all of which add nuance to complex social interactions.

If we simply exclude gestures from communication, we miss a whole sphere of human interaction. Moreover, when trying to interact across cultures, especially if we do not speak a common language, a focus on universal gestures can go a long way towards bridging otherwise intractable differences.

The trick, of course, is knowing which gestures mean the same thing in different cultures. While this blog tries to help you build this knowledge, it can only do so much. Instead, we encourage you to take advantage of Humintell’s specialized cross-cultural training programs to make you a better people reader, regardless of where in the world you happen to be.
