Study Notes

Memory Concepts

  • Memory encompasses processes that allow the retention and recall of information over time.
  • Encoding transforms information into a format suitable for storage in memory.
  • Storage involves maintaining encoded information for future use.
  • Retrieval refers to the process of accessing stored information for conscious awareness.

Stages of Memory

  • The stage model of memory classifies memory into three stages: sensory memory, short-term memory, and long-term memory.
  • Sensory memory briefly holds environmental information.
  • Short-term memory actively retains information for about 20 seconds.
  • Long-term memory provides permanent storage for encoded information.

Memory Techniques

  • Maintenance rehearsal keeps information active in short-term memory but is ineffective for long-term storage.
  • Chunking enhances short-term memory capacity by organizing information into manageable units.
  • Working memory focuses on immediate cognitive processing, including perception and language.
  • Elaborative rehearsal connects new information to existing knowledge to aid retention.

Types of Memory

  • Procedural memory stores knowledge of how to perform tasks, like motor skills.
  • Episodic memory involves autobiographical events, including details of time and context.
  • Semantic memory contains general knowledge and concepts not based on personal experience.
  • Explicit memory requires conscious recollection, while implicit memory aids performance without awareness.

Memory Retrieval

  • Retrieval cues are prompts that assist in recalling stored information.
  • Retrieval cue failure occurs when cues are inadequate, hindering memory recall.
  • The tip-of-the-tongue experience is characterized by partial retrieval of information.

Memory Effects and Phenomena

  • The serial position effect suggests individuals recall the first and last items in a list better than those in the middle.
  • The encoding specificity principle states retrieval is more successful when the context during encoding matches that during recall.
  • Context effects illustrate how environmental factors influence perception and memory recall.

Memory Distortion

  • Mood congruence signifies that an individual's current mood can affect memory recall of related information.
  • Flashbulb memories are vivid recollections of significant shocking events with details remembered clearly.
  • The misinformation effect occurs when post-event information alters the recall of episodic memories.
  • Source confusion can lead to misattributing the origin of a memory.

Memory Loss and Disorders

  • Forgetting refers to the inability to recall information that was previously encoded.
  • Encoding failure results when the brain fails to create a memory link.
  • Retroactive interference makes it difficult to recall old information due to interference from new learning.
  • Proactive interference hinders comprehension of new material due to previously learned information.
  • Amnesia can be retrograde (loss of past memories) or anterograde (inability to form new memories).

Key Figures in Memory Research

  • Suzanne Corkin extensively studied memory's neural basis, particularly in amnesia patients.
  • Hermann Ebbinghaus introduced the forgetting curve, illustrating the decline of memory retention over time.
  • Eric Kandel’s research on Aplysia revealed neural mechanisms underlying learning and memory.
  • Elizabeth Loftus is recognized for her work on false memories and eyewitness accounts.
  • George Sperling's discovery of iconic memory pertains to visual sensory memory.

Other Important Concepts

  • Long-term potentiation describes the strengthening of synapses based on recent patterns of activity.
  • Dementia refers to a decline in cognitive abilities impacting daily functioning.
  • Imagination inflation indicates that imagining an event that didn’t happen can lead to false recollections.
