Padma Shri Scientist reveals why emotional reactions are rapid, while thoughtful decisions require time

Why do human beings sometimes react instantly to an emotional situation but require considerably more time to understand it, evaluate its consequences, and arrive at a thoughtful conclusion? According to Dr. Ajai Kumar Sonkar, Padma Shri Awardee Scientist and Marine Biologist, the answer lies partly in the remarkable interaction between two important brain regions: the amygdala and the prefrontal cortex.
Dr. Sonkar explains that the amygdala is deeply involved in evaluating emotional significance, particularly potential threats, whereas the prefrontal cortex plays an important role in reasoning, planning, evaluating alternatives, and regulating emotional responses.
“An emotional reaction may begin within milliseconds, but a thoughtful decision may require seconds, minutes, or even hours. The difference is not merely the speed of the brain; it is the depth and complexity of information processing,” Dr. Sonkar said.
Amygdala: The Brain’s Rapid Emotional Response System
The amygdala is an important component of the brain’s emotional processing network. It helps identify emotionally significant information and can rapidly initiate responses associated with fear, anxiety, anger, excitement, or other emotional states.
Research involving human intracranial recordings has documented amygdala responses to emotional stimuli within fractions of a second. However, emotional processing continues through multiple stages rather than ending with the initial response.
Dr. Sonkar further said, “When we encounter something emotionally disturbing, our first reaction may emerge before we have fully understood the situation. That is why an immediate reaction should not necessarily be considered our final judgment.”
Prefrontal Cortex: The Brain’s Reflective Decision-Making Network
The prefrontal cortex is associated with higher cognitive functions, including working memory, planning, reasoning, cognitive flexibility, and the regulation of behaviour.
Unlike an immediate emotional response, a considered decision may require the brain to compare information, retrieve memories, examine possibilities, and evaluate consequences.
“Giving ourselves time before responding to an emotionally charged situation allows greater opportunity for reflective thinking. The objective is not to suppress emotion, but to understand it before allowing it to determine our behaviour,” Dr. Sonkar explained.
From Milliseconds to Minutes: Understanding the Difference
The initial neural responses associated with emotional processing may occur within approximately 100–300 milliseconds under certain experimental conditions. More elaborate interpretation, conscious evaluation, and decision-making can continue for seconds or considerably longer.
Dr. Sonkar cautions that there is no universal stopwatch separating the amygdala from the prefrontal cortex. Both regions communicate continuously, and emotional as well as cognitive processing occurs through interconnected neural networks.
“An individual may react emotionally within a fraction of a second, yet require several seconds to formulate a response. If the matter involves relationships, responsibility, uncertainty, or long-term consequences, thoughtful evaluation may take minutes or hours. This is not because the prefrontal cortex simply switches on later, but because meaningful decisions require more extensive processing,” he said.
The Science of Pausing Before Reacting
According to Dr. Sonkar, one of the practical implications of this neuroscience is the importance of developing the habit of pausing before responding.
A brief pause during an emotionally intense situation can provide an opportunity to regulate attention, reconsider assumptions, and select a more appropriate response.
He further said, “The moment we become aware of our emotional reaction, we create an opportunity for conscious regulation. Instead of responding automatically, we can ask ourselves: What exactly has happened? What am I feeling? Is my interpretation correct? What could be the consequence of my response?”
This principle is particularly relevant in interpersonal communication, conflict resolution, stressful situations, and important personal decisions.
Reacting Is Automatic; Responding Can Be Conscious
Dr. Sonkar emphasises that emotional responses are not inherently wrong. Emotions provide valuable information about our experiences and environment. Problems may arise when an immediate emotional reaction is mistaken for a complete understanding of reality.
“The amygdala and prefrontal cortex are not enemies. They are partners in the functioning of the human brain. Emotional intelligence emerges not by eliminating emotion, but by integrating emotional information with thoughtful reasoning,” he said.
A Scientific Message for Everyday Life
The distinction between reacting and responding offers a powerful lesson for everyday living.
A person who learns to pause, observe, and reflect may become better equipped to manage emotionally challenging situations. Mindfulness, attentive listening, and deliberate reflection can support this process, although they do not guarantee that every decision will be correct.
Dr. Sonkar concluded, “Nature has equipped us with both rapid emotional responses and sophisticated reflective capacities. Wisdom lies in knowing when to react, when to pause, and when to think more deeply. Sometimes, a few seconds of conscious awareness can prevent a response that we might otherwise regret for years.”
The central message is simple: An emotional reaction may be instantaneous, but a wise response deserves time.
