Understanding Memory and Brain Processing by Victor Fitzsimons

There are 2 main types of Memory

How Memories Are Established in the Brain:
The process of memory formation involves the hippocampus (for encoding), the amygdala (emotional significance), and the prefrontal cortex (retrieval and processing). The brain "codes" sensory input, consolidates it into short-term memory, and if important enough, it can transfer it into long-term memory.

Short-Term Memory (STM)

Often called working memory, this holds information temporarily (from a few seconds to a minute) and has a limited capacity (7 +/- 2 items).

It's where active thinking happens.

Long-Term Memory (LTM)

This stores information for extended periods (hours to lifetime). It’s more permanent and has vast capacity. It’s where facts, experiences, and learned skills reside.

Retention refers to the ability to keep or retain information over time.
Transfer refers to applying knowledge or skills learned in one context to a new, but related, context (i.e., transferring knowledge learned in one lesson to a real-world situation).

How they relate to learning

Retention is crucial for long-term learning, and transfer is essential for making that knowledge applicable outside of a controlled learning environment. Both processes rely heavily on the brain’s neural pathways and how information is encoded, stored, and retrieved.

How trauma can affect memory

Trauma can disrupt normal memory processing, especially in areas of emotional regulation (handled by the amygdala). For individuals who have experienced trauma, memories may be fragmented or hard to access. Trauma can also lead to hypervigilance or avoidance of memories, affecting how new information is stored and recalled.

Impact in Learning Environment

Trauma can affect attention, focus, and emotional regulation, which in turn can impair memory and learning. Understanding this helps educators adjust their approaches for students who have experienced trauma, using trauma-informed practices.

Improving Students' Memory

For learners with trauma, it's crucial to create a supportive environment that fosters safety and emotional regulation. This might include strategies like allowing for breaks, offering predictability in routines, or providing opportunities for mindfulness. A safe environment enhances focus, making it easier for learners to absorb and retain information.

Using Sensory Experiences:

Engaging multiple senses (visual, auditory, tactile, etc.) during learning activities helps strengthen memory retention. For example, using multimedia, physical objects, or interactive activities can solidify concepts and make them more memorable. Sensory experiences activate different areas of the brain, reinforcing learning.

Making Meaningful Connections:

Help learners relate new information to their personal experiences or prior knowledge. This can be done through analogies, storytelling, or real-world examples. When learners can connect new knowledge with something they already know, it increases retention and enhances transfer.

Brain's response to trauma

vf007 — 2025-01-23 03:07:05 UTC

Trauma can impact the brain’s ability to process and store information, particularly in areas related to memory and emotion, such as the hippocampus and amygdala. This disruption can make it difficult for individuals to focus and retain new learning.

Helping Students who are Stressed

Educators can support students dealing with trauma by using trauma-informed practices, such as creating a safe learning environment, establishing consistent routines, and fostering positive relationships. These approaches help mitigate the effects of trauma and support better emotional and cognitive functioning in the classroom

Meditation for Memory

Mindfulness meditation has been shown to increase hippocampal density, which enhances memory and focus while reducing stress and anxiety, ultimately improving cognitive functions. Awareness meditation takes this a step further by using self-awareness to navigate emotions and reactions, promoting better decision-making, which can indirectly improve memory through reduced stress and anxiety.

Retention Requires Rehearsal

vf007 — 2025-01-23 03:14:56 UTC

Retention of new information is significantly influenced by rehearsal, which is the process of repeatedly processing and elaborating on the information. Without adequate rehearsal time and the ability to assign meaning to new learning, information is likely to be forgotten, especially when it is complex or abstract.

Primacy-Recency Effect

vf007 — 2025-01-23 03:15:50 UTC

The primacy-recency effect shows that during a learning episode, people tend to remember the first and last pieces of information best, while forgetting those presented in the middle. This is due to the limited capacity of working memory and how new information is processed and chunked over time.
