Landmarks in the Field of Nonverbal Behavior

We spend a great deal of time talking about Humintell’s work on nonverbal behavior, but it’s important to know that this is a wide and exciting field!

In a recent paper in the Journal of Nonverbal Behavior, a pair of researchers sought to map out the major authors and major papers that have dominated the field. Instead of just looking at new developments, this was an important way of seeing what the lay of the land in the field is, so to speak, and this sort of work is incredibly valuable to those trying to expand the field and to those trying to understand the academic consensus.

One of the exciting features of this research was also an analysis of the most frequently cited and published scholars in the field. We were proud to see Humintell’s Dr. David Matsumoto listed in the top five scholars!

In mapping the discipline, Drs. Pierrich Plusquellec and Vincent Denault leveraged a massive bibliographic database that included more than 200 million articles from thousands of journals, not limited to psychology. However, they subset this database to a series of important keywords that were relevant to nonverbal behavior and folded in citation counts to each article to determine its importance.

The first intriguing finding was a calculation of the most common words used in the titles of relevant articles. This tells us what most scholars tend to focus on and included “emotion,” “facial,” “expressions,” and “recognition.” However, these were often paired with applications including “children,” “psychiatric illness,” and “depression.”

Second, the study authors also tracked the frequency of highly cited articles over time. By looking only at the thousand most cited articles, they were able to track the development of seminal works and the emergence of increased interest in the field. They found that the field emerged during the 1960s but that most of these articles were actually quite recent.

This last finding indicates that, while the field has been developing for over 50 years, it has gained newfound emphasis and popularity recently.

These over-time findings were further explored by looking at how frequently used words over time, i.e. which words were most frequent during given decades. “Facial expression” tends to be one of the most frequent across the whole time period, though this was not so pronounced until the 1990s and 2000s.

So what exactly does this tell any of us about the field?

A main takeaway seem to be the primacy of studying facial expressions within nonverbal behavioral studies, which is notably different from looking at body language or even microexpressions more narrowly.

Another important conclusion is also the exciting nature of the current period of this field. It appears that the last 15 years have experience a sharp increase in interest, academic and otherwise, in nonverbal behavior, and we are optimistic that this trend continues!

How to Read Microexpressions and Improve Your Observation Skills

This special blog showcases an interview recently done with Humintell’s own Dr. David Matsumoto.

The online behavior lab, Science of People, asked him to delve into the question of how we can use observational skills to determine other people’s intent and to assess the possibility of deception, as well as his own personal background.

Science of People emphasized Dr. Matsumoto’s recent research finding that microexpressions can be helpful in detecting deception. In fact, we blogged on this just recently! They also walked readers through the universal basic emotions, which is of course a staple for those who follow this blog.

However, Dr. Matsumoto consented to give a little bit more insight into what he means by “observational skills” and into his vision for the future of relevant research.

Specifically, he emphasized that the observational skills necessary for effective deception detection are not just something that we passively or naturally do. Instead, we have to actively try to employ these abilities, thus developing our skills.

Quite simply, he said, “If you want to get better at this skill, observe.”

As an exercise, Dr. Matsumoto suggests counting the number of times the interviewer, Vanessa, gestured with her right hand during the interview. Can you count the final number? The correct answer is revealed at the end of the video!

Or, if you are more ambitious, he recommended watching interviews with politicians and celebrities. When these are off script, you can see how people’s subtle expressions betray their emotions, and you can begin to learn to see those same patterns in everyday conversation.

Of course, there is no one thing that can betray somebody’s emotion. Instead, clusters of nonverbal behavior are incredibly important, albeit understudied. This can include changes in the type or frequency of gestures or in how their speech changes. Not only does this depend on the specific emotional context, but it depends on the individual too.

It is those sorts of behavior clusters that Dr. Matsumoto expressed interest in studying going forward. How do a combination of factors uniquely specify emotional states?

Not only does microexpression research demand that sort of synthesis, but Dr. Matsumoto went further in emphasizing the need for even higher level coordination amongst relevant researchers.

Because this field demands that many individual pieces come together, the current state of study suffers from a “Humpty Dumpty” problem where the disparate findings must be put together. This can be challenging and underlines the need for increased coordination.

Nonverbal Behavior in Relationships

holding-hands-coupleWe keep talking about nonverbal behavior with strangers, but what role does it have in close interpersonal contexts?

There is plenty of reason to think that this is important! We pick up on our romantic partner’s nonverbal behavior, even if we don’t realize that we are doing it. In a recent paper, a team of psychologists led by Dr. Ruddy Faure sought to understand whether implicit partner evaluations led to significantly different nonverbal behavior, and what that means for relationships.

This research appears motivated by questions of what exactly makes some relationships last and others fall apart. Some time ago, we blogged on Dr. John Gottman’s answer to this question. He argued that the slow growth of contempt between partners will almost invariably drive them apart over time.

Dr. Faure’s answer is not quite different, focusing on the idea of implicit partner evaluations. These basically entail our often automatic feelings towards a partner, where we begin to think badly or critically. This is a shift from previous attempts to study relationship dissolution, because most past research has focused primarily on explicit emotions.

However, this research grappled with the impressive question of how to really measure those things? How can you track the implicit evaluations and nonverbal behaviors present in relationships?

To address these concerns, the team organized an intensive project where couples were videotaped discussing contentious topics. They were then asked to complete a personal diary over 8 days. Before engaging in the taped interview, each partner was asked to assess implicit partner evaluations based on subtle questionnaires.

Importantly, the taped interviews allowed for a better understanding of what nonverbal behaviors were being displayed, especially given the implicit questionnaires completed beforehand.

Overall, they found that more positive implicit evaluations did lead to more constructive nonverbal behavior. This means that the less a partner had negative associations with their partner, the kinder they expressed their emotions during the videotaped interview.

The connections to Gottman are then pretty clear. Contempt would lead to much lower implicit evaluations, emphasizing our partners’ flaws, for instance. This would inevitably come out, even if unintentionally, when trying to discuss something contentious, in the form of negative body language.

While this sort of thin may not even be consciously noticed, it certainly has the potential to impact our interactions.
