The Personality of Walking

Often in crowded cities, we clash with those who walk much more slowly, or we hold up those who walk faster. Is there an explanation for this variation?

According to a team of researchers, personality traits may help predict how quickly or slowly we will walk. In a creative study, published in Social Psychological and Personality Science, Dr. Yannick Stephan and his team looked at over 15 thousand individuals, tracking how quickly they walked and also measures of traditional personality traits like extraversion and neuroticism.

We rarely talk about walking speed, but isn’t it an important nonverbal behavior?

While past research has connecting walking speed to health, there are also compelling connections between personality traits and health. For instance, those high in neuroticism and low in extraversion tend to exercise less frequently and be in poorer health. While gait speed might not sound that important, this study attempts to further explore the relationship between our physical health and our personality.

For context, the researchers utilize a measure of five personality traits that has long been common in psychology. This includes neuroticism (a disposition towards negative emotions), extraversion, openness to new experiences, conscientiousness (a measure of organization and self-discipline), and agreeableness.

It might be suspected that data on gait speed would be hard to come by, but amazingly the researchers employed an incredible treasure trove of information on individuals’ personality traits and walking speeds. Some of this was even longitudinal, allowing an understanding of these relationships over time.

Overall, they found that personality features successfully predict walking speed, even when measured years before. They tended to find similar relationships even between different samples and age/demographic groups.

Extraversion and conscientiousness consistently predict higher walking speeds. This may seem intuitive, if we imagine an extraverted friend or someone who is quite self-disciplined. However, the opposite was true of neuroticism which declined more steadily over time and was associated slower gait speeds initially.

These findings are consistent with previous research finding the same connections between those personality types and health. By seeing how this is manifest in gait speed, a great deal of information can be inferred and further explored about how we express our personalities. Gait speed can then be used as a reliable predictor for both health and personality type, benefitting researchers, patients, and diagnosticians alike.

While this might seem a bit far afield from Humintell’s usual work, it really isn’t. Gait speed can be seen as an important nonverbal behavior!

Can you attempt to read people based on their pace? Rather than being in a hurry, they might just be really extraverted!

The Functions of Emotions

function of emotionsEmotions are surely important in our lives, but it is amazing to see just how foundational they really are in how we experience the world.

Humintell’s own Drs.  David Matsumoto and Hyisung Hwang put together a comprehensive book chapter exploring that very question. They emphasize the crucial role that emotions have in intrapersonal, interpersonal, and cultural contexts. This can show how emotions are critical both at the very micro-level of human life but also at the macro-social level as well!

The first of these, intrapersonal, focuses on how emotions operate internally, as opposed to interpersonal functions which shape how we interact with other people. In all of these contexts, emotions give meaning to events and inform who we are on a fundamental level.

At the intrapersonal level, emotions can help us respond to events and handle potentially dangerous situations. For instance, we need not rationally contemplate every situation and instead can rely on emotions, like disgust or fear, when we need to act quickly. This helps determine not only our behavior but also our physiological state, as our emotional response triggers physical reactions, like saliva reduction or increased blood flow.

Similarly, when we reflect on our memories, our emotions help frame them and determine how we conceptualize ourselves and our past. They create a sort of value-laden narrative which unites what would otherwise be loosely connected facts. This helps motivate us going forward, shaping what behaviors we practice, such as a desire to work hard to avoid past mistakes.

Emotions are at least as important interpersonally. They help us communicate information to other people and help us better understand other people and their intentions.

Our facial expressions convey social signals, not only about our emotional state but also about how we might act in the future. By reading other people’s expressions we can then better understand them, using emotions as a medium for that understanding.

Similarly, emotions play a huge role in understanding interpersonal relationships. When researchers examine the subtly displayed emotions of married couples, for instance, signs of contempt or disgust can significantly predict later behaviors, such as divorce.

But it is not just at these micro levels that emotions matter. In fact, emotions are key to understanding macro-level social and cultural concerns.

Our human societies rely on incredibly complex norms of behavior and require that people all over the world act within a coordinated and organized way. In many ways, this is rooted in emotional commitments. Our culture provides a system of norms and meanings that shape how we interface with the world.

Hopefully, this overview helps you see just how foundational emotions are in our lives. It is not just a matter of seeing the relevance of emotion in any one given situation, but instead it is necessary to see how emotions shape so many areas of our lives, individually and collectively.

Jan van Hooff visits chimpanzee “Mama”, 59 yrs old and very sick. Emotional meeting

Can we recognize emotions amongst other species? Can they recognize ours?

If our emotional recognition skills expand to other species besides humans, that tells us a great deal about the universality and evolutionary basis of our expressions, including our basic emotions. In this amazing video, Dr. Jan van Hooff visits an elderly chimpanzee, Mama, whom he had known many years earlier. Take a minute to watch the video and look for the moment where she recognizes the scientist’s face!

The moment of recognition is pretty hard to miss, with Mama’s face lighting up in what would be considered an obvious smile in humans. Even her vocalizations indicate pleased surprise and clear recognition. Then, her behavior changes from lethargic and apparently depressed to engaged and more active.

This seems like clear evidence that Mama is experiencing a similar process as humans do when we recognize other faces, and this would not be surprising as many emotional expressions are common across primate species. In fact, past research has found similarities between primate and human gestures.

As we previously blogged on, many gestures are common between chimpanzees, bonobos, and humans. This includes triumphant postures but also shooing gestures. Many of these are deeply rooted in our evolutionary history as well.

That fact should probably not be surprising as chimpanzees also express emotions in similar ways, with remarkably similar laughs!

So, maybe your takeaway is that by learning effective facial and emotional recognition, you can recognize not just humans but chimpanzees as well!
