Study Notes

Memory Types

  • Explicit Memory: Conscious, declarative knowledge, encompassing episodic (personal experiences) and semantic (facts and general knowledge) memory.
  • Implicit Memory: Unconscious, nondeclarative knowledge, including procedural (motor skills and habits) and classical conditioning (behavioral responses).

Implicit Memory Mechanisms

  • Associative Learning: Unconscious links between stimuli, e.g., dental drills associated with anxiety.
  • Priming: Activation of related concepts in memory, demonstrated through word associations (e.g., "money, withdraw, robbery").

Procedural Memory

  • Non-verbalizable knowledge of how to perform tasks, acquired gradually through experience rather than single instances.

Memory Performance Distinctions

  • Implicit and explicit memory show different performance levels due to:
    • Processing Levels: Depth of encoding affects memory retention.
    • Modality/Format: Memory performance can vary based on cues like font or case.
    • Retention Interval: Time between learning and recall influences memory accuracy.
    • Amnesic Patients: Differences in memory function can highlight dissociations between implicit and explicit systems.

Neuroanatomical Structures

  • Different memory systems may be supported by unique neuroanatomy, especially for declarative vs procedural memory.

False Memory

  • Influenced by misleading information post-event, evident in eyewitness testimony (Loftus, 1974).
  • Schema and Scripts: Memories can be distorted to fit existing cognitive frameworks.
  • Source Confusion: Difficulty distinguishing the origin of memories exacerbated by social pressures.

Flashbulb Memories

  • Vivid recollections of significant events, prompting questions about accuracy and retention (Brown & Kulik, 1977).
  • Rehearsal Effect: Frequent recollection may contribute to perceived accuracy over time.
  • Neisser’s study of Pearl Harbor emphasized the decay of flashbulb memories, paralleling other memories.

Research Insights

  • Talarico and Rubin (2003): Flashbulb memories decline in detail consistency at the same rate as everyday memories over time, indicating no greater accuracy.
  • Study comparing flashbulb memories of 9/11 demonstrated similar patterns of decay in vividness and reliability as regular memories.

Conway et al. Findings (2009)

  • Survey of 678 participants about memories of the September 11 attacks, with follow-up surveys revealing changes in recollection and confidence over time, supporting the view that flashbulb memories are not immune to decay.
