Emotional intensity and the individual

Let’s say you’re at home. Maybe you’re lounging indolently on the couch, feet up on the brown wood coffee table, television whining at you from across the room. Maybe you’re cooking tonight’s dinner, chopping vegetables with careful strokes, sliding the ever growing pile of peppers and onions and tomatoes into a hissing frying pan. Maybe not. Maybe you’re in another room when the fire alarm sounds, bleep bleep bleep, blaring its cacophonous melody into your generally peaceful home.

How do you react?

Do you scream? Do you calmly turn off the stove, flap a towel at the cloudy air around the smoke detector, and wait patiently for it to detect that there’s not actually a fire? Do you leap up from the couch, tripping over the coffee table in your panic, terrified of burning to death in your own living room?

The strength of your emotional response to this (or any) emotional stimulus is known as emotional intensity. Emotional intensity can be measured with psychological scales, such as the aptly-named Emotional Intensity Scale (EIS) developed by Bachorowski & Braaten (1994) [PDF]. The underlying if obvious assumptions of these scales are that some individuals experience all of their emotions more intensely than other individuals, and all individuals may respond with different strengths to the same stimuli.

Your personality influences your experience of emotions

You may already be familiar with the Big 5 personality factors: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (sometimes called Emotional Stability). (If not, look them up.) Robert McFatter, in his 1998 paper Emotional Intensity: Some components and their relations to extraversion and neuroticism [PDF], investigated the relation between temperament and the intensity of positive and negative emotions. (Positive emotions included happiness and pleasure; negative emotions included worry, guilt, anger, and sadness.) McFatter described and tested several models, all of which had slightly different predictions about how neuroticism, extraversion, and positive and negative emotional intensity are correlated.

  1. Larsen & Ketelaar model: The measures used to examine emotional intensity in this model tapped frequency of experienced emotions more than the intensity of single (and possibly infrequent) reactions. The model predicts that Extraversion is positively related to positive intensity and unrelated to negative intensity, and that Neuroticism is unrelated to positive intensity and positively related to negative intensity.
  2. Larsen & Diener model: This model draws on the theory that the intensity of experienced emotions is used to regulate arousal levels. Arousal level can be tied to Extraversion, so this model predicts that Extraversion is positively related to both positive and negative intensity. Larsen & Diener also predict that Neuroticism is similarly positively correlated with positive and negative intensity.
  3. Wallace, Bachorowski, & Newman (WBN) model: Extraversion is suggested to reflect a behavioral approach system and a behavioral inhibition system. Neuroticism is suggested to reflect the reactivity of an arousal system responding to the behavioral approach/inhibition systems that serves to prepare the individual to respond. This model accordingly predicts that Extraversion is positively related to positive intensity and negative related to negative intensity (and thus that Extraversion is overall uncorrelated with overall emotional intensity), and that Neuroticism is positively related to both positive and negative intensity.
  4. Gray’s model: This model predicts that the behavioral approach/inhibition systems form dimensions that are rotated roughly thirty degrees from the Extroversion and Neuroticism dimensions, so they don’t line up. The model predicts that Extraversion is positively related to positive intensity but only weakly negatively related to negative intensity. Similarly, Neuroticism is predicted to be weakly positively related to positive intensity, and positively related to negative intensity. Gray’s model, furthermore, suggests that the negative emotions can be subdivided into anger/panic and anxiety/fear categories. These subcategories may have different relations to Extraversion.

Methods, Correlations, Analyses, Results

To test these models, McFatter gave a series of questionnaires to 1553 college students taking introductory psychology classes (596 male). Participants completed the 30-item EIS to examine positive and negative emotional intensity (14 items and 16 items, respectively), the Eysenck Personality Inventory (EPI) for measuring Extraversion and Neuroticism (in addition to subscales for impulsivity and sociability), and a third unrelated questionnaire.

Extravert, Introvert, Stable, Neurotic

Based on an initial factor analysis of the EIS, negative intensity was separated into two groups: anger/frustration (hereafter referred to as “anger intensity”) and non-anger, such as worry, guilt, and sadness (referred to as “non-anger intensity”). This result supports Gray’s theory that two separate negative emotion systems exist.

Consistent with both Gray’s model and the WBN model, Extraversion was shown to be positively related to positive emotional intensity (r=0.19, P<0.0001), negatively related to non-anger emotional intensity (r=0.18, p<0.0001), and unrelated to anger intensity (r=0.02). In plainer terms, individuals with high Extroversion scores tended to experience more intense positive emotions and less intense negative emotions.

Neuroticism, on the other hand, was shown to be positively related to all three kinds of emotional intensity, though less strongly to positive intensity (r=0.18, p<0.0001) than to non-anger or anger intensity (r=0.56,p<0.0001 and r=0.45,p<0.0001, respectively). That is to say, individuals with high Neuroticism scores tended to report experiencing more intense emotions overall. This is consistent with Gray's model.

A couple other interesting results:

Females reported significantly higher emotional intensity than males overall, with the largest difference seen in negative intensity (0.411, p<0.0001).

The positive relation between Extraversion and emotional intensity was stronger among people with a high Neuroticism score.

Neuroticism and emotional intensity

It’s hard to tell without reading a pile of psychology papers, but the fact that Neuroticism was positively related to positive emotional intensity was surprising. Previous results found a negative relation, though several of these had measured emotional intensity with a different scale–one that seemed to confound frequency and intensity of the experienced emotions. The WBN model, relatedly, claimed that Neuroticism reflected general emotional reactivity. (Recall the personality factor’s other name: Emotional Stability.) So McFatter investigated.

He found that when looking at the difference of the positive intensity and negative intensity scores, the relative emotional intensity was negatively related to Neuroticism, as in those previous studies. However, when examined on their own with the other variables controlled, the relations of both positive and negative intensity to Neuroticism were positive. The WBN model only explained a portion of the story.

McFatter’s results, overall, support Gray’s model and the WBN model, suggesting that the variations in positive and negative emotional intensity may be the result of separate emotion systems, but that they do have some common variation that may best be explained by their relations to Neuroticism.

Tibetan Buddhist Retreat

Monday, April 12th, 2010 at 6:04 am by Jacqueline

Prayer flags in front of the temple

Faded squares of fabric, strung together in repeating blue-white-red-green-yellow chains, crisscross the branches of bare-limbed trees. The gentle wind makes them flutter. Orange-gold light filters into the grassy meadow, touching a row of canvas tents and the temple house beyond. Tsechen Kunchab Ling: Temple of All-Encompassing Great Compassion. This is the seat of His Holiness the Sakya Trizin in the United States, a Tibetan Buddhist monastery established nine years ago.

I spent the past weekend there. The field work office at my college arranges this retreat every semester. Everyone I’ve talked to who has previously attended says wonderful things about it; this semester, one of my friends told me she was going: I should join her! I like learning new things, so I signed up. A good decision: I didn’t return all chill and zen, as one friend told me his roommate had, but I certainly gained a few new ideas and approaches to mull over, and dipped my hand into a previously unfamiliar piece of the world.

Medicine for one’s mind

The first evening, the twenty-something students–most from my college, four from another–gathered in the shrine room, sitting cross-legged on cushions as we listened to Khenpo Kalsang introduce Tibetan Buddhist philosophy. He began by telling us, “Do not take any of what I say on faith. Take it through analysis, if there is some benefit in it for you.” Religion, he said, is like a drugstore full of medicine. You do not go to the drugstore and buy everything in it–you just buy what would be beneficial to you now. You believe the other medicine may have just as much value, but in other situations, not this one.

We discussed the foundations: the Three Turnings of the Wheel of Dharma; the four noble truths; karma; defilements; the six perfections. When we talked about the giving, and how one should try to give what one could to other sentient beings (in the form of material items, kind words, protection, and so on), Khenpo Kalsang shared a story of the Buddha, and how the Buddha had given his flesh so that a family of hungry tigers could eat. “So,” a fellow student asked, “Giving one’s life for another being is the ultimate gift?”

Khenpo Kalsang, he smiled, and shook his head. “Only if you feel no regret,” he said. “If you feel regret, it destroys the merit.” Until then, preserve your own life, and do not give away anything that would cause you regret. This struck a chord. Self-preservation above all else, unless the right situation arises.

Knowing and understanding

Later, I talked to the resident nun, Ani Kunga, about psychology and cognitive science. She had studied psychology for a while in grad school, but now holds the view that psychologists are going about understanding the mind and understanding the knower and what knowing is the wrong way. “Psychologists,” she said, “study the brain and the self externally. Ever since the 1920s, their science has been about observation of behavior, questionnaires, recordings of electrical brain activity. But the mind can only be known by you, the person whose mind it is.” She said philosophy and epistemology were doing it right: looking at experiences from the inside.

A big overlap exists between Tibetan Buddhism, psychology and cognitive science. All three examine the distinction between the self and others, between the observer and the observed, between knowing and the knower. I agree with Ani Kunga to some extent–only so much can be known about the mind from external observation. But this doesn’t mean that there isn’t merit to such studies, nor that nothing of use can be learned in that way.

Tibetan Buddhist philosophy also approaches the mind and the self from the inside. During a second philsophy session, Khenpo Kalsang translated a sutra about a king who received advice from the Buddha. This sutra delved into some questions about the nature of the self, whether the self is a delusion, and how the clinging of self is a defilement. I intend to discuss it in more depth later, so stay tuned.

Compassion training and prayer flags

In the afternoon, a group of us gathered outside for a meditation session with Ani Kunga. Sunshine melted lazily through the tree branches above, a breeze animating the branches’ shadows so they danced between our cushions. Compassion and anger were the session’s topics. The key message:

“If there’s something you can do, why are you unhappy? Just do it. If there’s nothing you can do, why are you unhappy?”

Ani Kunga explained several off-session and one on-session technique for dealing with negative emotions (anger, hate, irritation, stress, jealousy, and so on). All the methods built off the idea that you are in control: anger is an emotion, and you can change your emotions. Stay tuned for a more in-depth post on the topic.

Another of the day’s activities was making prayer flags. As Ani Kunga explained, “Prayers, wishes, hopes, aspirations–someone, many people, may share those with you. Hanging the prayer flag shares your prayer with everyone else in the world. This may do no good at all, but it may–if everyone hopes and wishes and dreams and aspires, perhaps it will do good. It may not. But if no one shares their prayers, it will certainly do no good. So on the offchance that it will help, why not?”

Never done

This weekend reminded me that I’m not done learning. If I stay still long enough, if I’ve achieved a relatively constant level of happiness and satisfaction, I forget that I can and should continue to seek out new ideas and approaches, and incorporate beneficial ones into my life. A person is never “done,” and so, I’ll continue to observe and discuss and study, trying to pick the directions in which I’ll change, and trying to make tomorrow better than today.

Ever onward and ever upward.
