I. Introduction: When Conflict Causes a Brain Freeze
The parties had been negotiating for three hours when one of them suddenly froze.
“I know the answer is in my head somewhere,” she said, frustrated. “I just can’t seem to think today.”
Mediators see this moment often. A normally thoughtful person becomes reactive, forgetful, or stuck. It can look like stubbornness or bad faith. But what if something else is happening inside the brain?
Conflict is often treated as a communication problem, a legal problem, or a relational problem. Yet beneath every entrenched dispute lies a biological reality: sustained conflict alters how the brain processes information and makes decisions.
Mediators regularly observe this without naming it. A disputant struggles to recall important details. Another becomes fixated on a single outcome. Someone normally thoughtful becomes reactive or withdrawn. These behaviors are not simply strategic or personality-driven. Often, they reflect a nervous system operating under prolonged stress.
This article explores how conflict affects executive function (and diminished RAM), how fatigue (lack of REM) contributes to impasse, and what dispute resolvers can do to restore cognitive clarity. By understanding how stress shifts the brain from reflective reasoning to threat response, mediators can better structure conversations that promote sound decision making and durable resolution.
II. RAM: Executive Function and the Brain on Conflict
When a conflict drags on, it often takes its toll first on the brain. Clients begin to notice a change in their mental capacity and regulation. What is happening is a change in their brain’s executive function. Executive function refers to the brain’s operating system — the set of cognitive processes housed largely in the prefrontal cortex that allow individuals to:
- Plan
- Regulate emotions
- Access memory
- Generate options
- Assess consequences
- Make long-term decisions
In mediation, these functions are essential. Without them, disputants cannot meaningfully evaluate proposals or envision life beyond the dispute.
Under sustained stress, however, executive function is compromised. The brain reallocates resources toward immediate safety. This shift is sometimes called an “amygdala hijack,” though in reality the brain is functioning as designed — prioritizing perceived threat over future planning.
When this occurs, disputants may appear rigid, reactive, forgetful, or emotionally volatile. Recognizing this neurological shift allows mediators to respond strategically rather than interpret these behaviors as resistance or bad faith. Being able to explain to clients what is happening to them also helps them to normalize their experience.
A. Executive Functions Most Affected by Conflict
When stress narrows cognitive bandwidth, several executive capacities are predictably impaired. Understanding these impairments helps mediators adapt process and pacing.
Common impairments include:
- Working memory — Clients have trouble holding short-term facts in their heads or being able to access long-term memories.[1] This can also look like the brain protecting itself from harmful or scary thoughts, a type of dissociative amnesia.[2]
- Idea creation — This works similarly to accessing memory. To form a new idea, the brain has to be able to understand it – to see it or visualize what it will look like. Then this concept is stored as a future memory. But in a state of heightened anxiety, creativity is diminished, making it harder for clients to create new ideas.[3]
- Inhibitory control — This means that clients might shout out frustrations, slam a door, or eye roll – behaviors that they could normally contain.[4]
- Cognitive flexibility — Perhaps you are trying to shift gears and propose a new course of action to your client, and they appear stuck on a previous thought. [5]
- Task initiation — This could be a hesitancy to try something new or proceed to the next phase of a case. In severe cases, this could also look like clients having a hard time taking a shower, getting documents prepared, and driving to your office to make a meeting on time.[6]
- Emotional regulation — This can present in a lot of different behaviors: lashing out in anger over small things, catastrophizing simple frustrations, wallowing in despair after a simple setback, ignoring advice, flipping quickly between manic and depressive episodes.[7]
- Planning and prioritizing — This overlaps with the inability to form memories or ideas: without being able to picture the future, it becomes very difficult to create a goal to form the tasks needed to reach that goal. Without being able to identify the tasks, it is almost impossible for the brain to prioritize or decide what to do next. This results in decision paralysis.[8]
- Time estimation — Stanford researchers tested this on Ken Kesey in the 1960s, where they had him estimate when a minute had passed, then had him estimate again after giving him LSD. What they found was that the brain was so focused internally on the anxiety that it had lost some of its external connection and had a wildly distorted view of the passing of time. Meaning that subjects might think they had been working on a task for an hour or a minute and could not remember how long they had been somewhere.[9]
- Problem solving — This is where we really start to see the effect on our clients, and this is often why they come to us for help. The inability to access memories, form ideas, set goals, experience normal creativity, or break goals into tasks or priorities means that it is incredibly hard for clients to figure out the steps to solve a problem.[10]
- Metacognition — This means thinking about your thinking. It involves awareness, monitoring, and regulation. For instance, if a client is extremely anxious, it is the ability to notice that they are anxious, to pause and take a calming breath, and to avoid difficult decisions until they have calmed down.[11]
- Understanding others’ motivations — When children grow up in high-conflict environments, a common behavior is to overestimate others’ aggressiveness, known as hostile attribution bias[12]. Their brain has learned to protect and prepare itself for the worst, and so it assumes the worst in others[13]. If someone asks an innocent question, the brain assumes malicious intent and becomes defensive and possibly aggressive. In conflict, the brain often makes the same overassumption of aggression, as well as an inability to understand the other person’s behaviors.)
When pressed for information, a stressed disputant may become more reactive, have a hard time recalling information, or have difficulty forming a plan. Any dispute resolver would understand why it is so important for a client to have access to his or her full executive functions. It is hard to have a conversation with a client who cannot fully access their memories, identify goals, solve problems, be creative, or regulate their emotions.
Mediators and disputants alike often underestimate how much stress has affected their cognitive capacity.

In prolonged conflict, what disputants often need is not judgment but structure — a temporary substitute executive function while their system stabilizes.
B. How Conflict Erodes Executive Function
Consider a morning where your spouse snaps at you – and it distracts you during the day. Your brain is trying to make sense of something that does not make sense – why would someone who is supposed to be nice say something that was unkind? Your brain uses up much of its cognitive processing ability to make sense of the nonsensical. Say, as an example, you replay the conversation repeatedly in your brain, and you are pulled back to it during meetings, while you are driving, or trying to respond to an email, and it is as if 87% of your brain’s executive function is being used up by that conversation, leaving only 13% of your brain to handle basic functions. Just like when your computer freezes when too many tabs are open, your brain’s “RAM,” or access to process and form memories, is severely diminished. Even small unresolved conflict consumes cognitive bandwidth. Now magnify that to a divorce, business dissolution, or probate dispute.
C. Where Needs-Based Decision Making Fits: A Brief Note on Maslow and the Amygdala
Abraham Maslow (1908-1970) was an American psychologist. He is credited with shifting the goal of psychology from “What is wrong with this person?” to “What would help them grow?”[14] To understand their growth, he created his most famous contribution, Maslow’s Hierarchy of Needs. He explains that humans move through 5 phases of needs:
- Physiological needs – food, water, sleep, shelter, basic survival
- Safety needs – security, stability, health, protection from harm
- Love and belonging – relationships, connection, community, intimacy
- Esteem – self-respect, confidence, recognition, achievement
- Self-actualization – personal growth, purpose, realizing one’s potential
The goal for parties in mediation is to have them in Phase 4 or 5 – Esteem and Self-actualization. However, when parties are going through a long-term conflict where they begin to feel threatened, parties often slip into Phase 1 or 2. Their brain prioritizes the need for safety, stability, and sleep.
The Effect of Conflict Limbo
Prefrontal cortex function:
In an ideal conflict, our clients are calm and thinking logically, making decisions from their prefrontal cortex, likely in Phase 4 or 5 of Maslow’s hierarchy. The prefrontal cortex, working with the hippocampus, is the part of our brain that is able to retrieve memories and form future goals. It can understand the long-term impact of current behaviors. [15]
A divorcing client operating from her prefrontal cortex, for instance, might be able to remember all of the good times her children have had with their father, and set up the parenting plan so that the children can have many more wonderful moments with him.
Under chronic stress, however, the amygdala becomes dominant. The brain prioritizes short-term safety over long-term goals.
This is not dysfunction. It is protection.
But when protection dominates for too long:
- The hippocampus (memory integration) weakens
- The prefrontal cortex is consulted less frequently
- Threat detection remains elevated
Disputants may then operate from short-term pain avoidance rather than long-term stability.
Stress hormones:
There are 3 main hormones that we can thank for this decreased executive function.
- Adrenaline (epinephrine: creates an immediate, sharp spike in heart rate and energy, prepares the body for quick action)[16]
- Noradrenaline (norepinephrine: creates a myopic hyper focus, where the brain develops tunnel visions on the threat and tunes out the rest of the environment, making it difficult to observe nuance)[17]
- Cortisol (releases slowly and lasts longer; suppresses non-essential functions such as digestion and healing; reduces memory, learning, and emotional regulation)[18]
These hormones help explain the decrease we see in executive function. Clients become forgetful, fixate on one potential outcome, ignore other scenarios, become irritable, and experience a memory fog.
Dissociative amnesia:
Due to the inability to access memory, they are likely experiencing dissociative amnesia. They may replay the same event repeatedly. Or when pressed, they cannot seem to remember the timeline of an event or important details around it. When you press them for information, they will likely become stressed. This is a sign that they know the information is there, and they are frustrated that they cannot access it.[19]
They will likely become myopic about a certain outcome, despite you presenting other solutions. This is often due to the lack of cognitive flexibility and the norepinephrine in their system.[20] How these stress hormones present during the conflict resolution process:
- Reduced creativity
- Reduced empathy
- Unresolved conflict creates circular thinking loops.
- Irritability, especially when discussing painful parts of the conflict
- Poor communication choices
- Decision paralysis
- Assuming that people are being aggressive – trauma response
A mediator may hope to facilitate creative, forward-looking agreement design. But if a disputant feels unsafe — financially, relationally, or emotionally — the first task is restoring psychological stability. Only then can higher-order reasoning resume.
III. Impasse and the Fatigue Factor: When Conflict Moves from RAM to REM
After long-term exposure to conflict, the effects move from the brain into the body. One of the first factors affected is the ability to rest and move into deep sleep. Even after a full night of sleep, parties may wake up still feeling groggy.
Decision-making capacity deteriorates significantly when sleep is disrupted. Disputants who appear indecisive, emotionally fragile, or cognitively foggy may simply be neurologically depleted.
Sleep is the brain’s nightly repair cycle. When conflict prevents adequate REM sleep, emotional processing remains incomplete. Memories are not properly integrated. Emotions remain heightened. Relational conclusions cannot be formed.
The result is a feedback loop:
Unresolved conflict → poor sleep → heightened emotional reactivity → deeper conflict.
Recognizing this cycle reframes what might otherwise be interpreted as stubbornness.
A. How Sleep Works
The first 3 stages of sleep are called NREM – meaning Non-Rapid Eye Movement sleep. This is a lighter sleep; we often wake up and then fall back asleep. This stage is helpful for our body to get rest.[21]
- Phase 1: The brain is slowly disengaging from the outside world.
- Phase 2: The brain begins to process information.
- Phase 3: The 3rd NREM stage is the hardest to wake from. This is the deepest phase and most critical for our bodies to heal.
- Phase 4: This is the REM stage, necessary for processing emotions and relationships.[22]
The 4th stage of sleep is REM sleep, known as Rapid Eye Movement sleep. This stage can last about 90 minutes. What is interesting is that the brain is very active during this phase; it resembles wakefulness. This is often where people have vivid dreams, as they are trying to make sense of what happened during the day.
During the REM phase, the brain is performing three essential tasks. First, it consolidates memories. This means that the brain can process what it experienced during the day, and can decide which memory bucket to put it in: painful, helpful, harmful, crossed a boundary, etc. Next, our brain separates emotions from the experiences. Meaning that we can view a situation for what happened, instead of just how we felt about it. Finally, our brain forms conclusions about our relationships from those experiences.[23]
When REM sleep is impaired, disputants relive emotional charge without integration. They remember how something felt but struggle to contextualize what occurred. They remain stuck in the conflict.
B. The Conflict–Sleep Feedback Loop
Chronic hyperarousal prevents deep REM sleep. Without it, the brain cannot categorize experiences effectively. Emotional charge lingers.
This depletion directly affects negotiation stamina.[26]
C. Long-Term Effects of Poor REM
People only start to notice the long-term effects after consistent nights without Phase 3 non-REM and especially Phase 4 REM sleep. As people can go longer without sleep, they begin to notice themselves going through these phases:[27]
- Mood instability
- Cognitive fog
- Increased burnout
- Strained relationships
- Impaired decision making
IV. Chronic Stress & Cellular Aging
Sustained cortisol exposure affects cellular systems.
Chronic stress contributes to:
- Telomere shortening — Accelerated biological aging. Shortened telomeres are associated with faster biological aging, cardiovascular disease, diabetes, mental decline, and a poor immune system.[28]
- Oxidative stress — Reduced cellular energy production, the mitochondria are not functioning properly. People feel groggy, looking for junk food energy bursts, and increased caffeine intake.[29]
- Hormonal disruption — Progesterone drops first, then estrogen and testosterone; leading to difficulty reproducing and decreased libido.[30]
- Increased biological age markers — Chronic stress creates a biological age that is often 5-10 years older than their actual age, evidenced by increased wrinkles, crepey skin[31], thinning hair,[32] and abdominal fat. [33]
The implications are significant: unresolved conflict is not merely psychological. It is physiological.
V. Reflecting on Our Own System Errors
Mediators are not immune to these effects.
Extended exposure to high-conflict environments can impair executive function, sleep quality, and emotional regulation. Awareness of this reality is not self-indulgent; it is professional maintenance.
Recognizing one’s own cognitive depletion allows a mediator to:
- Adjust pacing
- Schedule breaks
- Set appropriate boundaries
- Seek supervision or peer consultation
A regulated mediator stabilizes the room.
VI. Resetting the System: Restoring Decision-Making Capacity
Almost all stress effects described above are reversible.
Mediators are uniquely positioned to help disputants regain cognitive clarity.
A. Cognitive Strategies
- Clarifying interests
- Breaking complex issues into smaller components
- Reducing extraneous cognitive load
- Reality testing
B. Somatic Strategies
- Structured breathing
- Vagus nerve activation and Polyvagal theory[34]
- Progressive muscle relaxation
- Grounding exercises (walking, feeling the floor, washing hands in cold water)
- Kinesthetic supports
C. Communication Strategies
- Gentle inquiry
- Curiosity framing
- Validation
- Safe exploration of painful material
These interventions are not therapy. They are process design tools that reduce stress and restore executive access. They help parties to feel a sense of control.
VII. Conclusion: Restoring Clarity in Mediation
Conflict is not merely a disagreement. It is a neurological event.
Sustained stress shifts brain function from reflection to protection. Fatigue compounds that shift. When disputants arrive at mediation, they may not have full access to the cognitive tools required for thoughtful negotiation. And most people do not recognize the toll it has taken on their brain and their body.
By recognizing executive depletion, sleep disruption, and stress physiology, mediators can structure conversations that restore clarity.
When stress decreases, executive function recovers.
When executive function recovers, meaningful negotiation becomes possible.
In this way, mediation is not only dispute resolution — it is cognitive restoration.
