System 1 System 2 role in memory formation

Can you explain the process of the interactions and coordination between system 1 thinking and system 2 thinking and the creation and use of long-term memories from short term memory,


Certainly! The interaction and coordination between System 1 and System 2 thinking, and the process of transferring information from short-term memory to long-term memory, are complex and integral to our cognitive functioning. Here's an overview of how these processes typically work together:


1. Initial Perception and System 1 Processing:

  • Perception: It all starts with the perception of information through our senses. This sensory information is initially processed by System 1, which operates quickly and automatically.

  • Immediate Response: System 1 makes rapid assessments based on this information, often based on past experiences or heuristic processing. This stage involves recognizing patterns, making quick judgments, and having immediate emotional responses.

2. Involvement of Working Memory:

  • Transfer to Short-Term/Working Memory: Information deemed important or interesting is then transferred to short-term or working memory. This is where System 2 begins to get involved.

  • Active Processing by System 2: Working memory, under the guidance of System 2, actively manipulates and processes this information. This might involve conscious reflection, analysis, comparison with existing knowledge, problem-solving, or reasoning.

3. Coordination Between System 1 and System 2:

  • Interplay in Decision Making: System 1 and System 2 often interact in decision-making processes. System 1 can offer intuitive responses, which System 2 may then evaluate and rationalize. Conversely, System 2 can override or modify the intuitive responses of System 1.

  • Feedback Loop: There's a continuous feedback loop between the two systems. For instance, System 2 might refine the heuristics used by System 1 based on new information or experiences.

4. Consolidation into Long-Term Memory:

  • Encoding Through Rehearsal and Meaning: For information to move from short-term to long-term memory, it typically needs to be encoded. This encoding often involves rehearsal, deeper cognitive processing, and linking the new information to existing knowledge or finding meaning in it.

  • Role of System 2: System 2 plays a crucial role in this process. It’s involved in deliberate learning, understanding, and the integration of new information with existing schemas in long-term memory.

  • Emotional Tagging by System 1: System 1 can also influence this process through emotional tagging. Emotionally charged events or information often have a higher likelihood of being remembered, a process influenced by System 1’s emotional responses.

5. Retrieval from Long-Term Memory:

  • Recall and Application: When we need to recall information, it is retrieved from long-term memory. This process can be influenced by both System 1 (through cues and patterns) and System 2 (through conscious effort).

  • Influence of Past Experiences: Previous experiences and knowledge, stored in long-term memory, can shape the way System 1 processes new information, leading to more refined intuitive judgments over time.

6. Adaptation and Learning:

  • Learning from Experience: The continuous interplay between System 1 and System 2, along with the transition of information from short-term to long-term memory, contributes to learning and adaptation. As we encounter new situations and reflect on them (System 2), we can adapt our intuitive responses (System 1) for similar future situations.

  • Modification of Heuristics and Biases: Over time, our experiences can lead to the modification of the heuristics and biases that System 1 uses, making them more accurate or contextually appropriate.

7. The Role of Attention and Focus:

  • Selective Attention: System 2, with its capacity for focus and attention, plays a critical role in determining what information is retained in long-term memory. It can selectively attend to certain details while ignoring others.

  • Influence on Memory Encoding: The focus and depth of attention given to a piece of information can significantly influence how well it is encoded into long-term memory.

8. Context and Environmental Factors:

  • Environmental Influence: The environment and context in which information is processed can affect how it's transferred from short-term to long-term memory. For instance, a conducive learning environment can enhance this process.

  • State-Dependent Learning: The emotional or physical state during learning (influenced by System 1) can affect the retrieval of these memories, a phenomenon known as state-dependent learning.


In summary, the coordination between System 1 and System 2 thinking is dynamic and plays a crucial role in how we process information and form memories. System 1 provides quick, intuitive responses, while System 2 offers deeper, more deliberate processing. This interaction, along with the mechanisms of attention and emotional tagging, facilitates the transfer of information from short-term to long-term memory, ultimately influencing our learning and decision-making processes.
