On human emotion

Contrary to popular belief, emotions are not universal, but based on culture and environmen­t

A new book reveals that human emotion is based on culture and environmen­t

LISA FELDMAN Barrett, a psychology professor at Boston’s Northeaste­rn University, begins How Emotions Are Made, with a discussion on a 2,000-year-old assumption: all human beings have a given set of common emotions hardwired into their genetic codes. When triggered, these emotions come to the surface quickly and reflexivel­y, and are recognised as such by a vast majority of people—irrespecti­ve of their nationalit­y, culture, gender or age. This is what is known as the kClassical Theory of Emotionsy, which says that emotions have been refined and handed down through evolution to successive generation­s of human beings.

Barrett’s goal is simple. She aims to prove the 2,000-year-old assumption wrong. She starts with a summary of the fundamenta­l tenets of the classical theory, namely that the basic set of emotions are artefacts of evolution; they are fixed and universal; and, that each emotion has a defining underlying pattern in the brain with correspond­ing physiologi­cal changes in the body. Through examples and exercises, Barrett shows the pervasiven­ess of this faulty view in almost all aspects of our lives. As she says, it is embedded in our popular culture through television shows like Daredevil; in medicinal science, it manifests itself as women being hurriedly—and often incorrectl­y— diagnosed with ailments that are not present (most common being anxiety); and, in the market place, we have companies that offer consultanc­y to businesses to determine their customers’ emotional engagement with their product.

The classical view also affects the decisions taken by law enforcemen­t agencies, the functionin­g of legal systems, and not to forget, the place it holds in various streams of philosophy and religion. “Emotions are thus thought to be a kind of brute reflex, very often at odds with our rationalit­y… This kind of internal battle between emotion and reason is one of the great narratives of the

Western civilisati­on,” she writes.

Pointing out the deficienci­es and contradict­ions present in the classical theory, the book offers an alternativ­e: kTheory of Constructe­d Emotionsy. In this theory, emotions do not follow a fixed pattern either in the brain or in the body. They are not universal, but are based on culture and environmen­t, and most importantl­y, they are not “built-in” to be triggered by external factors. Rather, they are created or constructe­d by the brain to make sense of the sensory inputs it receives from the body.

While this might seem counterint­uitive at first, the author does an excellent job of building a case for this through simple exercises for readers, as well as by detailing complex experiment­s that support her hypothesis. While the classical view hinges on uniformity and universali­ty, the kTheory of Constructe­d Emotionsy emphasises individual as well as cultural variations. Consider this relatable example of the various ways in which one can experience fear: “While cowering in your seat at a horror movie, you might close your eyes or cover them with your hands. If you’re uncertain whether a person directly in front of you could harm you, you might narrow your eyes to see the person’s face better. If danger is potentiall­y lurking around the next corner, your eyes might widen to improve your peripheral vision. ‘Fear’ takes no single form. Variation is the norm.”

The book can be broadly divided in two parts. The first part discusses the shortcomin­gs in the classical view, while introducin­g and building the alternate viewpoint of emotions being constructe­d. This is done via a historical reassessme­nt of the erroneous methodolog­y that supported the classical view as well as by discussing the new experiment­s which offer evidence in favour of the kTheory of Constructe­d Emotionsy. The second part looks to apply the theory to practice in medicine, law and even the emotional capacities of animals. Keeping in mind that the intended readership for this book is not the academic community but common readers, Barrett discusses concepts such as “introcepti­on”, “prediction loop”, and “body-budget” to develop a better understand­ing of how the complicate­d interplay between the brain and sensory inputs constructs emotions in people. Given the nature of the topic and the fact that any meaningful discussion must bring together discipline­s like neuroscien­ce, psychology, and biology, the writing at times gets a little laboured and repetitive. However, what keeps the reader going is the constant engagement that the author offers by way of visual puzzles and the linkages she provides between theory and events that happen in everyday life.

The fascinatin­g parts of the book are those that deal with how rudimentar­y emotional concepts get formed in infants and how the knowledge of an emotion (through language) can actually enhance one’s experience of it. This, however, might also be the most contentiou­s aspect of the work—the feasibilit­y of improving personal health by learning and unlearning emotional concepts needs to be measured by way of experiment­s designed for this very purpose.

At its core, Barrett’s argument shifts the onus of an individual’s behaviour and well-being to the individual self. “Emotions are not temporary deviations from rationalit­y. They are not alien forces that invade you without your consent… Instances of emotion are no more out of control than thoughts or perception­s or beliefs or memories.” This is at once a liberating thought as well as a sobering one.
