Does Music Elicit Universal Emotional Responses?

It’s no mystery that major and minor chords in western music makes us feel good. But could this be because of an evolutionary trait?

Recent research led by Eline Adrianne Smit and colleagues from the MARCS Institute for Brain suggests this could be the case.

Turn to any major pop radio station in the Western world and you’ll likely recognize some familiar features in the songs including:

  • A formulaic structure
  • Themes of romance
  • A catchy melody in a major scale
  • A song less than three and a half minutes

These unique features of modern music are designed to make the audience feel good, so we listen on repeat. But why do these songs make us feel good?

For the last few decades, psychologists have wondered if there are features to music that elicit universal emotional responses in humans.

Could certain elements of music be hard-wired into the human central nervous system?

A Musical Study

A recent study tested how different communities with varying levels of exposure to Western music would respond emotionally to major melodies and minor melodies. According to Discover Magazine, “At least in Western cultures, major and minor melodies and harmony heavily influence emotional responses to music. Major chords and progressions are associated with positive emotions, and minor chords and progressions are associated with negative emotions.”Smit and colleagues asked musicians and non-musicians in Sydney, Australia as well as different communities from Papua New Guinea with varying degrees of exposure to Western music, to associate major and minor melodies with either happiness or sadness.

The Results

The researchers found that the degree of familiarity with Western music corresponded with the association between major melodies with happiness, and minor melodies with sadness.

While this association was present for some groups in Papua New Guinea, researchers did not find evidence for this association in the community that was the most remote.

This study suggests that familiarity through cultural exposure plays and important factor when associating major and minor melodies with happiness and sadness respectively.

Interestingly, major chords tend to appear more frequently than minor chords in popular music and research shows that humans are likely to attribute positive emotions to things that we are familiar with.

Universality in Music?

Lead researcher Smit also thinks there could be some associative conditioning at play. She makes the important point that people typically don’t listen to music in isolation. Instead we listen to music that fits the context of our situation.

For example, we would usually hear major music at an event like a wedding, whereas we might hear minor music at a funeral.

If specific features of music are combined with emotionally laden events often enough, then we will likely associate that musical feature with that specific emotion.

Some psychologists have suggested that music was a sort of social glue in our evolutionary history, helping to facilitate the development of humans as a deeply social species.

While this study does support that culture reinforces the association between major and minor melodies with happiness and sadness, Smit does note that, “there is still absolutely the possibility that particular aspects of music might be universal.”

Universal Emotions in Music

In similar research conducted in 2016, Psychologist Heike Argstatter sought to determine whether universal basic emotions are recognizable in music across cultures.

This study built on her previous research which found that, within one Western culture, both trained musicians and laypeople consistently categorized the same musical sequences into categories based on the same basic emotions.

Dr. Argstatter then sought to extend these findings to audiences in disparate cultural settings.

The results? Dr. Argstatter found evidence that all participants, regardless of culture, would identify the same emotions in the same pieces of music. This was especially true for happiness and sadness.

Disgust and Fear Linked To More Acidity In Stomach

We’ve all experienced “gut feelings” but a new study out of Sapienza University supports the idea that these feelings could be tied to physiological changes. Researchers in Rome investigated how emotional states such as disgust and fear could affect acidity levels in the gut.


The Methodology

Giuseppina Porciello and her team asked 31 men whose average age was 24 to take a pill that measures pH levels in the gut.

The men then watched videos that elicited feelings of disgust, fear, and happiness while the pill sensor travelled down their gastrointestinal tract.

After watching each video, the men completed a questionnaire to rate the intensity of their emotions.


The Results

After watching the videos that elicited feelings of disgust and fear, the participant’s stomach pH level wasmore acidic than it was at a baseline measurement.

Those with the most acidic pH reported feeling the most disgusted and fearful. It is unclear whether a particularly acidic stomach heightens these emotions or if experiencing these emotions results in more acidity.

The participants who reported feeling happy, regardless of the video they watched, had a less acidic pH in their stomach.

Porciello and her team are now carrying out a similar study on female participants.


The Brain/Gut Connection

This research reinforces models that suggest the gastric network plays a major role in our body’s emotional responses.

As stated by the Harvard Medical School, the gastrointestinal tract is sensitive to emotion. Anger, anxiety, sadness, elation — all of these feelings (and others) can trigger symptoms in the gut.

The brain has a direct effect on the stomach and intestines. For example, the very thought of eating can release the stomach’s juices before food gets there.

Feeling disgust in the pit of your stomach isn’t unusual. In fact, self-reported ‘body maps’ of emotions often associate negative emotions with the gastric system.

It’s not just a mental thing either – recordings of the electrical activity in the gut’s muscular wall also reflect our experiences of revulsion.

Our bodies appear to be driven to ramp up gastric activity when we experience things we ought to stay clear of, evoking a sense of nausea.


Universal, Psychological Themes

It’s important to remember that research has demonstrated that, despite many differences (and similarities) in the specific types of events that trigger emotions in us, there are universal, psychological themes associated with each of the seven universal emotions – anger, contempt, disgust, fear, happiness, sadness, and surprise.

A psychological theme is the basic, most elemental way in which our minds process and evaluate any event in terms of what the event means to us psychologically. These themes are mostly concerned with our welfare.

The fact that there are universal, psychological themes associated with basic emotions means that the same underlying, psychological themes trigger the same emotion in all humans around the world, regardless of differences in race, culture, nationality and any other demographic characteristic.

So what are some quick descriptions of themes for the basic emotions of disgust and fear?

Disgust – Contamination

Disgust is triggered when our minds appraise something that is dirty, rotten, offensive, or contaminated.

 

Fear – Threat

Fear is triggered when our minds appraise something as threatening, or potentially threatening, or sense of self. The sense of self that is threatened can be our physical self as well as our psychological self.

Analyzing Alex Murdaugh’s Body Language

Alex Murdaugh's Body LanguageThe Alex Murdaugh trial has garnered much attention in recent days, and for good reason: a public figure with a lot of money is tried and convicted of a vicious crime. As with many criminal trials in popular culture, the demeanor of the defendant has received a lot of attention.

In this brief blog, I’d like to discuss a little bit about how reading people and the analysis of body language can help get greater insights into the minds of others. At the same time, I’d like to discuss some of the trials and tribulations of doing so without a solid empirical and experiential basis.

First of all, we should acknowledge the context within which we are observing behavior, which is a trial of a public figure that is being televised. In such a trial, questions and responses are often practiced and polished before they are raised in the court.

Oftentimes the questions that are asked are fixed and those asking questions don’t have the freedom or the luxury to go wherever they want to, as in a free-flowing investigative interview.

The astute observer should realize that reading behavioral indicators of mental states is clouded by such circumstances. That is very different than a spontaneous investigative interview conducted behind closed doors outside of public and television view.

“Anywhere, Anytime”

Many people have commented on the defendant’s verbal answer that he did not kill his wife and son “anywhere, anytime.” (see 0:19 in the video above)

Certainly the use of such language raises doubt about the veracity of that statement because those adverbs seem to make it appear that the suspect is trying to convince the questioner (or the jury) of the denial.

Yet, one has to temper such interpretations because the suspect was asked whether he killed members of his family several times prior, and one of those times the attorney asking the question (in this case, the defense attorney) actually used those very same words.

Thus, when Murdaugh said those same words, it was difficult to know whether those words came spontaneously from his head or was given to him by the person asking the question. The response was contaminated by the way in which the questions up to that point were asked.

Murdaugh Head Nods

When Alex Murdaugh was asked if he killed his family, he says “No, I did not,” while nodding his head up and down.

When Alex Murdaugh was asked if he killed his family, he says “No, I did not,” while nodding his head up and down.

A body language expert can tell you that means he’s lying. His body gave away the truth while his words lied. #MurdaughTrial #Liar #AlexMurdaugh pic.twitter.com/ZYGi5EsIvS

In that same response, Murdaugh nodded his head several times when making the denial. Many people will be quick to suggest that that head nod was clearly contrary to the denial, using the head nod as a sign of deception (nodding yes while denying).

But hold on; Murdaugh nods his head almost continuously at times, even when not being asked a question or even speaking. That behavior may be a residual effect of a drug addiction.

Yes, although he is likely clean during this testimony, such behavioral effects (e.g., tremors, fidgeting, twitching, tics, etc.) can continue in individuals who have been afflicted with drugs even when they are clean. Thus, jumping on such single instances of behavior and drawing definitive conclusions is difficult and should be done with caution.

Compounding this issue is that head nods are also used to illustrate or animate speech, and not just as signs of verbal “yes” or agreement. Could Murdaugh have been nodding when denying as an emphasis of his denial rather than a contradiction?

This is the differential that I believe a cautious behavioral analyst should engage in.

Cross-Examination of Murdaugh

In fact, later when the DA was cross-examining Murdaugh, he gave a similar denial with the multiple head nods, which was a similar communication package as that described immediately above.

The problem with this other instance, however, was that the DA asked if Murdaugh had “annihilated” his family; thus, Murdaugh’s head nods could be an emphasis of his denial given the explosive nature of the word in the question itself.

Compounding all of this further were the vehement and somewhat emotional ways questions were addressed to Murdaugh by both his attorney and the DA. When interpreting behaviors associated with responses in such situations, it becomes very difficult to separate the behavioral signs of mental states related to his own state of mind and its contents and his reactions to the emotional ways in which the questions were being delivered.

Would Murdaugh have produced a different package of behavior with the denial if he were asked calmly or with less vocal intensity? Probably so.

Thus, attempts to analyze the situations above, and others like it, are difficult and sometimes futile because they are somewhat contaminated by context and the demeanor of the questioners themselves.

As a result, we have to look elsewhere in his testimony for demeanor that is clearer and can clean up some of these differentials in interpretation. In fact, those existed. (Can you find them?)

My point is this blog is that sometimes reading people and using behavioral indicators of mental states are not as easy as some portray. By the way, in our workshops, we provide the kind of textured and nuanced way of reading people that is especially effective for interviewers.
