Remembering, Forgetting, and Distortion

Encoding Memory

  • Mnemonic devices: memory strategies that help you remember; method of loci: memory palace; visual cues; acronyms
  • Chunking: combining concepts into groups; other grouping techniques: categories + hierarchies
  • Spacing effect: massed vs. distributed practice: fast but easy to forget vs. solid learning
  • Serial position effect: primacy effect; recency effect - start & end are the easiest to remember

Storing Memory

  • Rehearsal: meaningful rehearsing (elaborative rehearsal) promotes memory retention
  • Autobiographical memory: memories connected to our own lives or selves; more memorable
  • Ebbinghaus' forgetting curve: memory decays fast (50-80%) in first days, and then slower
  • Infantile amnesia: inability to recall the first two to three years of lives; normal development process; shows memory is affected by developmental limitations

Storage processes affected by physical impairment

  • Retrograde vs. Anterograde amnesia: forgetting the past vs. unable to form new memory
  • Alzheimer's disease: a brain condition that affects memory, thinking, and behavior, common cause of dementia

Retrieving Memory

  • Retrieval: Recall (remembering without cues, e.g. essay) vs Recognition (relies on retrieval cues; e.g. multiple choice)
  • Retrieval cues: a cue/clue to remind you, to help you retrieve memory
  • Overlearning: rehearsing/practicing something so well that it's resistant to forgetting
  • Priming: a cue encountered earlier activates similar concepts -> identify/respond to them faster
  • Context-dependent memory: recall is easier in the same environment of encoding, e.g. classroom
  • Mood-dependent memory: recall is easier in the same mood of encoding, e.g. happy/angry
  • State-dependent memory: recall is easier in the same physical state of encoding, e.g. drunk
  • Testing effect: taking tests during the learning phase facilitates long-term retrieval
  • Metacognition: thinking about thinking; understanding of your thinking/memory strategies

Forgetting and Others Challenges

  • Tip-of-the-tongue phenomenon: you know something, but jsut can't recall it at the moment
  • Proactive vs Retroactive interference: what you learn earlier vs later can affect your learning
  • Repression: burying traumatic memory into unconscious (psychodynamic theory)
  • Misinformation effect: wording of questions asked to retrieve our memory influences our memory itself -> memory reconstruction / confabulation
  • Source amnesia: sometimes we forget how/where our declarative memory comes from
  • Constructive memory (memory reconstruction/confabulation): changing your memory when recall, due to influence or to fit a schema
