Understanding Memory Storage and Decay: Ebbinghaus and Long-Term Potentiation (LTP)

Explore the theory of storage decay and how the passage of time affects memory retention. Discover the role of the hippocampus in storing explicit memories and the cerebellum and basal ganglia in storing implicit memories. Learn about the importance of Long-Term Potentiation (LTP) for efficient learning. Understand the differences between recognition and recall and the concept of priming for memory retrieval. Explore state-dependent and context-dependent memory, the serial position effect, and the impact of emotions on memory formation.

Presentation Transcript

  1. Improving Storage Decay Theory – Ebbinghaus The passage of time causes forgetting. The longer information is not accessed, increases the chances of forgetting it.

  2. Memory Storage Explicit memories are stored in the hippocampus – like a save button. Implicit memories stored in the cerebellum and basal ganglia (procedural)

  3. Long-Term Potentiation (LTP) As you learn something, the firing of neurons in your brain increases in efficiency and speed. When LTP is disrupted, learning fails.

  4. Recognition vs. Recall Recall – remembering without cues (fill-in the-blank test) Recognition – remembering items shown to you (multiple choice test). Which do you think is easier?

  5. To retrieve a specific memory from the web of associations, you must first activate one of the strands that leads to it. This process is called priming. Priming

  6. Retrieval Issues State-Dependent Memory – recall is easier if in same “state” as when learned. If learn while drunk, may need to be drunk to remember. Context-Dependent Memory – recall is easier if situation is similar to when learned. Serial Position Effect - recall is easier for the first items (primacy effect) and last items (recency effect) in a list -- Primacy effect reflects long-term memory -- Recency effect reflects short-term memory

  7. Emotions and Memory Flashbulb Memories: - Stress hormones provoke the Amygdala – fear center of the brain - Creates a memory trace in the frontal lobe and basal ganglia - Bakes in emotional memories, but blocks neutral ones. - Extreme Stress hurts this process… why some people do not test well.
