Learning isn’t just about acquiring new information but how the brain encodes, strengthens, and applies knowledge. As leaders, educators, and L&D professionals, understanding the science of learning can help us design better training programs, foster more engaging workplaces, and support professional growth that aligns with how the brain works.
But what happens when stress, trauma, or workplace toxicity interferes with the learning process? How can leaders create environments where learning, adaptability, and leadership development thrive?
Let’s dive into the science behind learning, how stress and trauma disrupt it, and what leaders and L&D professionals can do to optimize learning for their teams.
🧠 How the Brain Learns: The Science of Neuroplasticity
At its core, learning is a biological process that involves structural changes in the brain. When we learn something new, our brains:
🔹 Form New Neural Connections – Neurons in the brain create new pathways for processing and storing information.
🔹 Strengthen Synapses – The more we practice or recall information, the stronger these connections become.
🔹 Use Myelination to Improve Speed – Myelin (a fatty substance) coats neurons, speeding up information processing and making knowledge retrieval easier.
🔹 Activate the Hippocampus – This brain region converts short-term knowledge into long-term memory.
🔹 Release Dopamine – When learning is engaging or rewarding, the brain releases dopamine, reinforcing motivation and retention.
How Learning Works in Adults
Adults learn differently than children because of prior experiences, cognitive maturity, and established neural pathways. This concept, known as andragogy, highlights that adults learn best when:
✔ Learning is self-directed—autonomy is key.
✔ Information is practical and relevant—adult learners must see how knowledge applies to real-world experiences.
✔ They can apply knowledge immediately – Learning needs to be action-driven.
✔ It’s social and interactive – Discussion, collaboration, and mentorship enhance retention.
💡 Example: A leadership training program will be far more effective if it includes hands-on activities, real-world problem-solving, and peer discussions, rather than passive lectures or one-size-fits-all content.
🚀 Key Takeaway: Repetition, emotional connection, and real-world application help solidify learning in the adult brain.
😟 The Impact of Stress and Trauma on Learning
While our brains are built for lifelong learning, they can also be severely affected by chronic stress and trauma.
🔴 Chronic Stress Shrinks the Hippocampus
The hippocampus (responsible for memory and learning) shrinks under prolonged stress.
This makes it harder to retain new information and retrieve past knowledge.
🔴 Amygdala Hijack = Learning Shutdown
The amygdala, the brain’s threat detector, overrides rational thinking in high-stress situations.
When this happens, the brain prioritizes survival over learning—meaning critical thinking and memory suffer.
🔴 Cortisol Disrupts Cognitive Function
High cortisol (the stress hormone) impairs focus, creativity, and problem-solving—all essential for learning.
💡 Example: Imagine an employee attending a leadership training session after experiencing a toxic workplace environment. If they were previously criticized for speaking up, they may now feel anxious, disengaged, or even resistant to participating—even if the content is valuable.
🚀 Key Takeaway: A stressed brain doesn’t learn effectively. Safe, supportive environments are critical for knowledge retention and professional development.
🏢 The Role of Workplace Culture in Learning
A toxic workplace doesn’t just harm employee well-being—it actively blocks learning, growth, and innovation.
🚨 Signs of a Workplace That Kills Learning
❌ Fear-Based Culture – Employees feel mistakes are punished rather than treated as learning opportunities.
❌ Lack of Psychological Safety – Team members are afraid to ask questions, challenge ideas, or admit gaps in knowledge.
❌ Constant Overload – Employees are too busy putting out fires to invest in personal growth.
❌ Micromanagement – Workers lack autonomy, which reduces their engagement in learning.
🚀 How to Create a Learning-Positive Work Culture
✅ Encourage Curiosity – Normalize asking questions, exploring new ideas, and continuous learning.
✅ Promote Psychological Safety – Allow employees to make mistakes and learn from them without fear.
✅ Provide Time for Reflection – Embed breaks, discussions, and application exercises into training programs.
✅ Foster Peer Learning & Mentorship – Create a culture where team members learn from one another.
✅ Use Experiential Learning – Replace passive training with real-world application, role-playing, and interactive problem-solving.
💡 Example: A company could implement a "Learning Hour" where employees are encouraged to explore professional development topics, share key takeaways, and apply them to real challenges.

🎯 Final Thoughts: Building a Learning Culture That Lasts
For leaders and L&D professionals, the real challenge isn’t just delivering training—it’s creating environments where learning is continuous, applied, and psychologically safe.
🔹 Reduce Cognitive Load – Break learning into microlearning experiences.🔹 Create Psychological Safety – Make employees feel safe to ask questions and experiment.🔹 Engage Emotionally – Connect learning to personal goals and real-world relevance.🔹 Minimize Stress – Give employees time and space to learn without pressure.🔹 Apply, Apply, Apply – Learning sticks when it’s used in real scenarios.
