Neuroscience of Emotions & Tools for Improving Emotion Regulation | Dr. Ralph Adolphs

KEYPOINTS

• 01

  Emotions are functional brain states defined by features like priority, valence, scalability and persistence.

  Adolphs, a Caltech professor of psychology, neuroscience and biology, admits theories (Joseph LeDoux, Lisa Feldman Barrett, Paul Ekman) look so different that philosopher Paul Griffiths once argued emotions don't exist as one category. His working view is a package of features. Priority means emotions interrupt whatever you're doing, an idea Nobel laureate Herbert Simon described decades ago. Valence (positive versus negative) may not be strictly required.

• 02

  Emotions scale and persist; reflexes don't.

  A reflex is all-or-nothing, like the knee-jerk. Fear scales with how close the threat is, from anxious monitoring of a distant bear to fleeing to panic, and emotions outlast their trigger. These two features come from David Anderson's mouse hypothalamus work. Sadness, Adolphs notes, has one of the longest time constants.

• 03

  You can study emotions without solving consciousness.

  Adolphs separates emotion states from the conscious feeling of them, just as vision and memory are studied in animals like horseshoe crabs with no claims about awareness. That lets researchers study emotion in animals by its functional features rather than by asking about subjective experience.

• 04

  Emotions are essential for decision-making.

  Citing Antonio Damasio's 1994 book Descartes' Error (Adolphs was then a postdoc with Damasio in Iowa), he notes that people with large frontal-lobe lesions who no longer respond emotionally can't make complex life decisions or organize their lives, because no option feels better than another.

• 05

  Regulation starts with emotional granularity: noticing and naming your emotions precisely.

  This idea, which Adolphs credits mainly to Lisa Feldman Barrett, means how finely you can perceive your own states. Once you're aware of an emotion you can apply strategies, mostly cognitive reappraisal (reinterpreting the situation). Huberman notes that real feelings are often a mix, such as confusion plus frustration, which makes naming them hard.

• 06

  The earlier you intervene in an emotion, the better, and both strategy and automaticity are trainable.

  Adolphs's first line is situational avoidance: structure your life so you don't land in situations that trigger the emotion you want to avoid. Once you're in one, what works is fairly individual. Two things can be trained: reappraising without overthinking, which can deepen the emotion, and the strength and automaticity of control, so regulation becomes smooth and effortless.

• 07

  We're far worse at reading emotions from faces than we think.

  Dog owners are convinced they can tell when their dog feels guilty, but in controlled tests they perform at chance. Adolphs says our confidence 'vastly outstrips our accuracy'. The posed, static Ekman photos used in labs (he used them in his own 1994 Nature paper) aren't what we see in life. Real faces are dynamic, and in practice we ask questions and use context.

• 08

  Where you 'feel' an emotion in your body reflects concepts, not measured physiology.

  The well-known body-map figure came from a PNAS paper by Lauri Nummenmaa and colleagues in Finland. Participants were shown a single word and drew where they thought they'd feel it; nothing in the body was measured. Adolphs stresses brain and body are tightly coupled, and work by Feldman Barrett and Tor Wager shows reliable but distributed brain signatures for basic emotions.

• 09

  Autism involves effortful, rather than automatic, social processing.

  In Adolphs's webcam eye-tracking studies, people watch Zoom-style videos, and those scoring higher on autistic traits or with a diagnosis make less eye contact, a pattern stable from month to month. He argues the core difficulty is cognitive load: consciously tracking eye contact, turn-taking and the rest is overwhelming when it isn't automatic.
