Theory of constructed emotion
The theory of constructed emotion (formerly the conceptual act model of emotion) is a scientific theory to explain the experience and perception of emotion. This theory was proposed by Lisa Feldman Barrett to resolve the "emotion paradox," which has perplexed emotion researchers for decades.
The emotion paradox is as follows. People have vivid and intense experiences of emotion in day-to-day life: they report seeing emotions like "anger", "sadness", and "happiness" in others, and they report experiencing "anger", "sadness" and so on themselves. Nevertheless, psychophysiological and neuroscientific evidence has failed to yield consistent support for the existence of such discrete categories of experience. Instead, the empirical evidence suggests that what exists in the brain and body is affect, and emotions are constructed by multiple brain networks working in tandem.
Despite this evidence, most other theories of emotion assume that emotions are genetically endowed, not learned, and are produced by dedicated circuits in the brain: an anger circuit, a fear circuit, and so on. This point of view is very much in line with common-sense conceptions of emotion. The theory of constructed emotion calls this assumption into question. It suggests that these emotions (often called "basic emotions") are not biologically hardwired, but instead are phenomena that emerge in consciousness "in the moment" from more fundamental ingredients.
Statement of the theoryEdit
The theory is given in simplified form as:
"In every waking moment, your brain uses past experience, organized as concepts, to guide your actions and give your sensations meaning. When the concepts involved are emotion concepts, your brain constructs instances of emotion."
In greater detail, instances of emotion are constructed throughout the entire brain by multiple brain networks in collaboration. Ingredients going into this construction include interoception, concepts, and social reality. Interoceptive predictions provide information about the state of the body and ultimately produce basic, affective feelings of pleasure, displeasure, arousal, and calmness. Concepts are embodied knowledge (from your culture), including emotion concepts. Social reality provides the collective agreement and language that make the perception of emotion possible among people who share a culture.
As an analogy, consider the experience of color. People experience colors as discrete categories: blue, red, yellow, and so on, and these categories vary in different cultures. The physics of color, however, is actually continuous, with wavelengths measured in nanometers along a scale from ultraviolet to infrared. When a person experiences an object as "blue", she is (unconsciously) using her color concepts to categorize this wavelength. And in fact, people experience a whole range of wavelengths as "blue."
Likewise, emotions are commonly thought of as discrete and distinct — fear, anger, happiness — while affect (produced by interoception) is continuous. The theory of constructed emotion suggests that at a given moment, the brain predicts and categorizes the present moment via interoceptive predictions and the emotion concepts from one's culture, to construct an instance of emotion, just as one perceives discrete colors. This process instantiates the experience of "having an emotion".
For example, if someone's brain predicts the presence of a snake as well as the unpleasant affect that would result upon encountering a snake, that brain might categorize and construct an experience of "fear." This process takes place before any actual sensory input of a snake reaches conscious awareness. In contrast, a "basic emotions" researcher would say that the person first sees the snake, and this sensory input triggers a dedicated "fear circuit" in the brain.
Earlier incarnations of the theoryEdit
Early incarnations of the theory were phrased in terms of core affect rather than introspection. Core affect is a neurophysiological state characterized along two dimensions:
- Pleasure vs. displeasure, measured along a continuous scale from positive to negative.
- High arousal vs. low arousal, measured along a continuous scale between these endpoints.
According to the original conceptual act model, emotion is generated when a person categorizes his/her core affective state using knowledge about emotion. This theory combines elements of linguistic relativity and affective neuroscience.
The term "core affect" was first used in print by Russell and Barrett in 1999 in Journal of Personality and Social Psychology where it is used to refer to the affective feelings that are part of every conscious state (as discussed by Wundt in his 1889 System der Philosophie). The term "core affect" also appears to have been used as a phrase that relates to neuropsychological understanding of behavior as a morbid affect at the roots of any type of human behavior.
