Definition and Function of Somatic Markers

Somatic markers, a concept introduced by Damasio in the 1990s, play a crucial role in understanding how emotions influence our decision-making processes. These bodily sensations, also referred to as gut feelings or hunches, serve as a link between our cognitive processes and the physical responses we experience in our bodies.

Somatic markers can be described as emotional bodily responses that arise from the interpretation of specific situations or stimuli. These responses are stored in our memory and serve as a reference point for future decision-making. When faced with a similar situation, our brain automatically retrieves these markers to guide our choices. According to this theory, somatic markers create the sense of knowledge. We often refer to this as a gut feeling.

The function of somatic markers is rooted in our evolutionary history. They provide a rapid way for our brains to evaluate the potential risks or rewards associated with a particular course of action. While our rational mind may deliberate and weigh different options, somatic markers provide an emotional shortcut to help us make quick and adaptive decisions.

Experience Creates Somatic Memories

Leslie Greenberg wrote, “a somatic state, a visceral experience, becomes a marker for a specific experience and is stored in memory. These somatic markers can then be accessed by present cues that evoke the emotional scheme” (Greenberg, 2015). In Damasio’s later work, he suggested that somatic markers are fundamental contributors to defining the self. He wrote that somatic markers are “feelings of knowing.” He further explains that “the construction of a conscious mind depends, at several stages, on the generation of such feelings” (Damasio, 2010).

Feelings create a sense of involvement in surrounding environments. The environment in a symbolic way becomes part of us when it activates somatic states. These states of feeling intertwine with the external triggers, creating personal meaning that we may draw upon in future interactions with similar stimuli.

Operant Conditioning and Somatic Markers

Damasio’s concept of somatic markers meshes well with many of the learning processes theorized in behaviorism. Greenberg wrote that, “any previous outcome that has been bad for you will be experienced as an unpleasant gut feeling, and you will tend to make decisions that do not lead to this kind of unpleasant event.” Basically, he is describing operant conditioning. We make connections between stimuli and related contingencies.

Greenberg continues, “In this way, the body is used as a guidance system, and it is emotions that guide our decisions by helping us to anticipate future outcomes on the basis of previous experiences stored in emotional schemes that activate gut feelings” (Greenberg, 2015).

Damasio describes the establishment of somatic markers as a connection between emotions and feelings through learning, establishing a way to predict future outcomes of certain scenarios. He wrote that “when a negative somatic marker is juxtaposed to a particular future outcome, the combination functions as an alarm bell” (Damasio, 2005).

The Role of Emotions and Somatic Markers in Decision-Making

Emotions, in general, have a significant impact on our decision-making. Somatic markers, specifically, allow us to anticipate the outcomes of our choices by generating emotional responses that guide our behavior.

Let’s consider an example: Imagine you are presented with two investment opportunities. While one option may seem financially rewarding on paper, it arouses a sense of unease, leading to a negative somatic marker. The other option, though less rewarding, invokes positive feelings and generates a positive somatic marker. These emotional signals help inform our decision, as they are based on past experiences and associated outcomes.

Reid Hastie and Robyn M. Dawes wrote that “in routine decision making, somatic markers may help us winnow down large choice sets into manageable smaller sets. Extremely bad options are quickly eliminated from consideration because somatic marker signals tell us to avoid them, so that we can reason about the serious contenders with our deliberate, conscious thought processes” (Hastie & Dawes, 2009).

Somatic Markers and Cognitive Deliberation

Damasio reminds that somatic markers are not enough. We still need cognitive deliberation. He wrote, “there is still room for using a cost/benefit analysis and proper deductive competence, but only after the automated step drastically reduces the number of options” (Damasio, 2005). Somatic markers create an immediate preference (bias); but deliberate evaluation may uncover elements missed by an immediate gut reaction of ‘like’ or ‘dislike.’ Decision-making is a dynamic interplay between logic and emotion, engaging multiple brain resources.

Neither logic without emotion, or emotion without logic is sufficient. We need both. In dialectic emotional therapy, they refer to the integration of the emotional brain and the logical brain as the wise mind. Damasio wrote that, “somatic markers probably increase the accuracy and efficiency of the decision process. Their absence reduces them” (Damasio, 2005).

Working Memory and Somatic Functions in Decision Making

According Damasio the complex functions of feeling and logic operate separately in different regions of the brain during decision making. According to Damasio, decision making is guided by somatic markers and working memory functions. “Ventral regions of the prefrontal cortex support decision making based on somatic markers, whereas dorsal regions of the prefrontal cortex working memory function” (Hinson et al., 2010).

The Brain’s Involvement in Somatic Markers

Somatic markers are not random bodily responses but are rooted in the way our brain processes information. Damasio’s research highlighted the crucial role of the brain’s prefrontal cortex and limbic system in generating and utilizing somatic markers.

The prefrontal cortex is responsible for evaluating long-term goals and consequences. Meanwhile, the limbic system, particularly the amygdala, processes emotional stimuli and generates bodily responses.

Somatic markers involve a feedback loop between these brain regions. Our emotions trigger bodily responses, which in turn feed back into the brain and influence our decision-making process. This bidirectional communication allows us to integrate emotional signals with cognitive evaluations, leading to more nuanced and adaptive decision-making.

Greenberg explains the physiological process in detail. He describes the use of somatic markers this way:

“These memory-based emotion schemes are triggered automatically, and when activated, cue the amygdala and anterior cingulate, which in turn lead to changes in the viscera; skeletal muscles; and endocrine, neuropeptide, and neurotransmitter systems—and possibly other motor areas of the brain. These changes, together with the often implicit meaning represented in the prefrontal cortex, generate human beings’ complex, synthesized, and embodied sense of self in the world. This sense, then, is symbolized in conscious awareness and formed into narrative explanations of self, other, and world” (Greenberg, 2015).

Somatic Markers and Communication

Allan Schore suggests that somatic markers play a significant role in communication. He explains that non-verbal expressions in response to stimuli coming from another person are received and translated through the involvement of somatic markers (Schore, 2003). I would venture to add that many of our nonverbal reactions are directly related to the activation of our own somatic markers.

Words and expression of feeling, especially from someone important to our wellbeing, send signals of warning. We predict the future possibilities of rewards and punishments from the verbal and nonverbal communications. The unconscious prediction set learned emotional patterns into action. Familiar dramas or comforting security emerge from the somatic markers.

Schore suggests that past traumatic experience may create a broken connection between the somatic markers and logical cognitions. These disconnections create states such as emotional detachment or alexithymia.

Schore wrote:

“Dissociation thus reflects the inability of the vertical axis of the right brain cortical–subcortical implicit self system to recognize and process external stimuli (exteroceptive information coming from the relational environment) and on a moment-to-moment basis integrate them with internal stimuli (interoceptive information from the body, somatic markers, the ‘felt experience‘) (Schore, 2009).

These dissociated states interfere with healthy interpretation of information flowing from interpersonal relationships. Unnatural fears ignite survival styles to protect against harm when harm is not present. The person trying to navigate a relationship without the wisdom of healthy somatic markers easily quickly dissolves into panic chaos with the slightest sign of difficulty.

Implications and Applications of Somatic Markers

Understanding somatic markers has significant implications for various fields, particularly in psychology, neuroscience, and behavioral economics. Here are a few notable applications:

• Clinical Psychology: Somatic markers play a crucial role in disorders such as anxiety, addiction, and decision-making impairments. Therapeutic interventions can focus on helping individuals recognize and regulate somatic markers to improve their decision-making abilities.
• Relationships: Somatic markers are essential to communication. Through feeling, we emotional connect, establishing emotionally intimate relationships where trust, security, and joy exist.
• Education: Educators can leverage somatic markers to facilitate better learning experiences. By incorporating emotionally engaging activities and experiences, they can enhance student engagement, memory retention, and decision-making skills.
• Business and Marketing: By understanding how somatic markers influence consumer behavior, businesses can tailor their marketing strategies to elicit the desired emotional responses. This knowledge can help in product design, branding, and customer retention efforts.

• Human Irrationality: This refers to the tendency of individuals to make decisions and take actions that deviate from logical reasoning or sound judgment. This phenomenon encompasses a wide range of behaviors, such as cognitive biases, emotional influences, and irrational beliefs.

A Few Words by Psychology Fanatic

Somatic markers provide a fascinating lens through which to understand the intricate interplay between emotions and decision-making. These bodily sensations serve as a bridge between our rational thoughts and emotional experiences, enabling us to make quick and adaptive choices when faced with uncertainty. By recognizing the profound impact these gut feelings have on our behavior, we can become more mindful of how they influence not only personal decisions but also broader social interactions. As we navigate life’s complexities, understanding somatic markers allows us to harness this innate guidance system, leading to better outcomes in relationships, education, and professional settings.

Moreover, delving deeper into the neural mechanisms behind somatic markers opens up exciting avenues for research and practical application. Researchers and practitioners alike can unlock new insights that enhance various aspects of human life—from improving mental health interventions by helping individuals recognize their emotional responses to refining marketing strategies that resonate on an emotional level with consumers. The implications are vast: by fostering awareness of our somatic markers, we empower ourselves to make wiser choices that align with our values and aspirations. Ultimately, embracing this knowledge enriches not only individual decision-making but also contributes positively to societal well-being as we cultivate deeper connections with ourselves and those around us.
