The state of a person at the moment of parting with money: the neuroscience of payment pain Introduction: the psychological and neurobiological nature of payment Parting with money is not just a neutral economic transaction, but a complex psychophysiological act, often accompanied by emotional discomfort, which neuroeconomists call the "pain of paying." This state represents an evolutionary paradox: we exchange abstract symbols of value for concrete goods, but the brain, set to conserve resources, interprets the loss of even these symbols as a threat. Neurobiological foundations: the brain in loss mode Key processes occur in the limbic system and the prefrontal cortex: Activation of the anterior insula. This area of the brain is the center for processing unpleasant sensory and emotional experiences — physical pain, disgust, social rejection. Studies using fMRI (such as those by neuroeconomist Knut Schmidt) clearly show: when a person parts with money (especially at overpayment or unfair price), the insula "lights up" as if in physical pain or seeing a suffering person. Suppression of the activity of the striatum. This part of the reward system is activated upon receiving money, pleasure, or anticipation of a purchase. At the moment of payment, its activity sharply decreases, which is subjectively experienced as disappointment or "coming down to earth." Intense work of the prefrontal cortex. It tries to balance the emotional surge from the loss of money with rational arguments ("I really need this thing," "I deserve this"). The level of "payment pain" directly depends on the outcome of this internal conflict. Interesting fact: In one experiment, participants were offered to buy a desired product (e.g., chocolate). When the price was displayed in large font, the activity of the insula was significantly higher, and the willingness to buy was lower than when the same amount was displayed in small, hard-to-read font. The brain reacts more strongly to more "obvious" losse ... Read more
