• Sensory memory briefly holds sensory input, filtering what is important for further processing.

• Short-term memory, also called working memory, temporarily stores and manipulates information for immediate tasks, typically lasting 20–30 seconds (Kandel et al., 2014).

• Long-term memory retains information over extended periods and is divided into explicit memory (conscious recall of facts and experiences) and implicit memory (unconscious skills and habits) (Kandel et al., 2014).

Memory formation follows four stages: encoding, consolidation, storage, and retrieval. The hippocampus plays a key role in transferring short-term memories into long-term storage, while synaptic plasticity strengthens neural connections through repetition and experience (Kandel et al., 2014). Factors like sleep, emotions, and engagement enhance retention.

In education and professional training, strategies such as multisensory learning, chunking information, and active recall improve retention and knowledge transfer, leading to more effective learning experiences (Kandel et al., 2014).

Retention improves when learning is engaging, repeated, and connected to prior knowledge. Neural pathways strengthen through practice, retrieval, and emotional connections, making information easier to recall. Strategies such as spaced repetition, active recall, and real-world applications help move knowledge into long-term memory (Sousa, 2022).

Transfer occurs when learning extends beyond its original setting. Near transfer applies skills to similar tasks, while far transfer allows knowledge to be adapted to more complex or unfamiliar situations. Strong transfer requires critical thinking, problem-solving, and repeated exposure to various experiences (Kandel et al., 2014).

Educators and trainers can enhance retention and transfer by incorporating hands-on activities, interdisciplinary connections, and real-world applications, making learning more meaningful and adaptable.

The hippocampus, which plays a central role in learning and memory, is highly sensitive to stress. Trauma can reduce its size and function, making it harder to distinguish between past and present experiences. This can contribute to increased alertness and emotional distress (Schweinsburg & Brown, 2018).

The amygdala, responsible for processing fear and emotions, becomes overactive after trauma. This heightened response can disrupt memory formation, leading to fragmented or intrusive memories, a common feature of post-traumatic stress disorder (PTSD) (Schweinsburg & Brown, 2018).

The prefrontal cortex, which supports rational thinking and impulse control, normally helps regulate the amygdala’s response to stress. However, trauma can weaken its function, making it harder to regulate emotions and retrieve memories. This can cause memory gaps, emotional instability, and difficulty processing traumatic events (Schweinsburg & Brown, 2018).

These brain changes can lead to intrusive thoughts, difficulty recalling details, and heightened emotional responses. Understanding how trauma affects memory can help educators and mental health professionals implement strategies that support recovery and learning.

For trauma-affected individuals, storytelling and community-centered learning foster a sense of belonging and support cognitive development (Cunningham, 2017).
