Memory I & II: Encoding, Storage, Retrieval, and Forgetting

Memory I & II

Previous Things to Remember (Cognitive Psychology & Attention)

  • Cognitive Psychology Focus: This field investigates how the mind processes information, and it has developed a specific set of tools for this investigation.

  • Attention Bottlenecks: Research on attention indicates significant bottlenecks in how we process information.

    • Practical Example: It is strongly advised not to talk on the phone while driving due to these processing limitations.

Today's Topics Overview

  • Defining what memory is.

  • Encoding: Exploring how information is put into memory, including concepts like Levels of Processing and Dual Coding.

  • Storage: Examining different memory storage systems: Sensory, Short-Term, and Long-Term memory.

  • Retrieval: Discussing how memories are accessed, including the debate between Decay and Interference.

  • Distinction: Differentiating between Short-Term Memory and Working Memory.

The Nature of Memory: Efficiency vs. Perfection

  • Common Misconception: Many people imagine memory as being like movie footage that can simply be rewound and replayed.

  • Biological Reality: Brains are metabolically expensive; a large brain like ours requires a significant amount of energy.

  • Evolutionary Design: Our brains evolved to be efficient in processing and storing information, rather than perfect, meaning they prioritize functionality over flawless recall.

  • Contrast: Everyday memory failures (e.g., forgetting what someone looks like) typically contrast with extraordinary feats of memory (e.g., remembering the exact order of 52 cards, as seen in memory champions).

    • Mnemonic Techniques: Advanced memorization strategies often employ techniques like
