🧠💬 Neuroimaging studies, including those using fMRI (functional Magnetic Resonance Imaging), have investigated how self-talk impacts the connections between different brain networks, including those related to motivation, self-awareness, and executive control. These studies reveal that engaging in self-talk, particularly positive self-talk, can lead to measurable changes in brain activity and connectivity.
Here’s how self-talk influences these networks:
▶️Motivation Network (reward system):
📑Self-talk and reward processing: Studies suggest that self-talk can affect the reward system, particularly the nucleus accumbens (NA), which is a key region involved in motivation and reward prediction.
📑Positive self-talk: Positive self-talk (e.g. self respect of affirmations) can lead to increased activity in the prefrontal cortex and impact the reward system, suggesting a potential for boosting confidence and motivation.
📑Negative self-talk: Negative self-talk, such as self-criticism, can trigger the body’s stress response and may decrease reward system activation, hindering motivation.
▶️Self-awareness network (default mode network - DMN):
📑Self talk and self-referential processing: Self-talk directly engages regions involved in self-referential processing, such as the prefrontal cortex and the DMN.
📑Impact on self-perception: The content and tone of our self-talk significantly influence how we perceive ourselves. Positive self-talk can foster compassion and boost self-esteem.
📑DMN and self-reflection: The DMN is actively involved in self-reflection and inner monologue. Excessive negative self-talk can lead to overactivation of the DMN and rumination, contributing to conditions like anxiety, depression, cardiovascular problems, sleep disturbances, digestive issues and can even lead to autoimmune conditions through chronic stress.
