Reference excerpt

Kent Charles Berridge (born 1957) is an American academic who is James Olds Distinguished University Professor of Psychology and Neuroscience at the University of Michigan. He is known for researching the brain mechanisms of affect, emotion, and motivation, and in particular, for originating the "wanting"/"liking" (or incentive salience) theory of motivation and pleasure, and, with Terry Robinson, the incentive sensitization theory of addiction. Berridge was a joint winner of the 2018 Grawemeyer Award for Psychology and was elected a member of the National Academy of Sciences in 2024.

Early life and education Berridge was born in 1957. He earned a Bachelor of Science from the University of California, Davis in 1979, followed by a PhD from the University of Pennsylvania in 1983.

Research Berridge conducts research relating to brain systems of motivation, affect, reward “liking”, reward “wanting”, emotion, fear, pleasure, drug addiction, eating disorders, and decision utility. He also studies natural syntactical chains of behavior (e.g. grooming; taste response patterns) in animals with colleague Dr. J. Wayne Aldridge. With Piotr Winkielman, he has investigated the issue of unconscious emotion in humans.

Liking Berridge is known for his work on the brain systems for pleasure (“liking”). Using an assay for “liking” called Taste Reactivity Analysis developed by taste researchers, Berridge measures facial palatability responses to tastes, which are similar between rodents, primates and humans. When something enjoyably sweet is tasted, characteristic licking responses occur. When something aversively bitter is tasted, gaping and head shaking occur. Berridge has helped identify "hedonic hotspots" in the brain, such as the nucleus accumbens and ventral pallidum, where opioid, endocannabinoid, and GABA neurotransmission coordinate the “liking” of tastes. Berridge postulates that these hedonic hotspots may be crucial for how the brain produces the hedonic pleasurable feelings common to delicious food, sex, drugs, and other rewards (a role previously thought to be played mostly by brain dopamine systems).

Addiction Berridge and colleague Terry Robinson have formulated a contemporary theory of addiction called the Incentive Sensitization Theory of Addiction. According to this theory, drug addiction develops from a sensitization of the mesolimbic dopamine system. Dopamine normally functions to attribute incentive salience to stimuli associated with rewards like food and sex, and triggers reward “wanting”. Drugs hijack this “wanting” system. Following repeated use of drugs, the dopamine system becomes hyper-responsive and drug cues become hyper-salient. This means drug cues are nearly impossible for addicts to ignore, and when they are encountered they can lead to intense cravings and/or relapse. This sensitized cue-triggered drug 'wanting' can persist for years after an addict quits drugs, and long after drug withdrawal has ceased. This fact may account for the tendency of former addicts to relapse to drug use after quitting, sometimes even after many years of abstinence.

Dopamine Berridge and Robinson helped redefine the role of mesolimbic dopamine in the brain, which had previously been viewed as a pleasure neurotransmitter. Dopamine is no longer widely regarded as a pleasure transmitter. Instead, dopamine is thought to mediate reward, that is, to attribute incentive salience to reward-associated stimuli.

Awards Berridge has been a Guggenheim Fellow and a Fulbright Senior Scholar. He shared the APA Award for Distinguished Scientific Contributions in 2016 and the 2018 Grawemeyer Award for Outstanding Ideas in Psychology with Terry Robinson. He was awarded the APS William James Fellow Lifetime Achievement Award from the Association for Psychological Science in 2023 and elected a member of the National Academy of Sciences in 2024.

Worked examples

Example 1 — a first encounter with Kent C. Berridge

Start with the simplest possible case. Write down what Kent C. Berridge claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kent C. Berridge before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kent C. Berridge ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kent C. Berridge

In research: Kent C. Berridge appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kent C. Berridge in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kent C. Berridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1957 births, 20th-century American psychologists, 21st-century American psychologists, so understanding it makes those chapters shorter.
In everyday life: Look for Kent C. Berridge outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
