Study Notes

Everyday Memory Errors and Memory for Personal Events

  • Memory for personal events includes autobiographical memories, flashbulb memories, inferred memories, and false memories.
  • Autobiographical memories are recollections of past events in one's life, including episodic memories (dated events part of life stories) and semantic memory (knowledge like birth dates).
  • Autobiographical memory tends to shift from episodic memory (detailed recollection) to semantic memory (less detailed general knowledge).
  • Flashbulb memories are vivid and detailed memories of shocking and emotionally significant events.
  • They are often considered more detailed than other types of memories but the existence of a special mechanism for them is debated.
  • Memory errors can arise from inferences, false memories, and personal biases.

Memory for Personal Experiences: Life Span Memory

  • Life span memory refers to how our memory varies over different periods of our lives.
  • Some events are remembered better than others, especially milestones and transition periods.
  • The reminiscence bump is a phenomenon where people tend to have enhanced memory for events during adolescence and young adulthood (ages 10-30).
  • Hypotheses for the reminiscence bump include the self-image hypothesis, the cultural life script hypothesis, and the cognitive hypothesis.

Memory for Personal Experiences: Flashbulb Memories

  • Flashbulb memories are memories of shocking and highly emotionally charged events.
  • These events tend to be remembered vividly and in great detail.
  • Evidence suggests that strong emotions can enhance the encoding and later recall of memory.
  • fMRI studies show that emotionally charged images evoke stronger activity in the amygdala, a brain region associated with emotion, which may lead to better memory.

How is Memory Constructed?

  • Memory is constructive, meaning it's not a mere recording of events but an active reconstruction based on various sources of information.
  • Memory incorporates prior knowledge, experiences, and expectations.
  • Bartlett's "War of the Ghosts" experiment showed how cultural schemas and expectations lead to distortions in memory recall over time.
  • Errors can occur due to changes, omissions, and constructions.

Factors Affecting Memory Construction

  • Experiences: Inferred memories, schemas, scripts and biases.
  • Personal biases: Egocentric bias, consistency bias.
  • Suggestions and misinformation effect.

Memory as a Video Recording

  • Memory is not as reliable as a video.
  • It is susceptible to errors by omission or distortion.
  • The speed and accuracy tradeoff in memory system is a characteristic.
  • Memory system is built primarily to work efficiently, similar to the perceptual system.

Eyewitness Testimony

  • Eyewitness testimony has shown to be unreliable and prone to errors.
  • These errors are largely due to emotions, familiarity, and suggestions
  • Factors such as weapons-focus effect, familiarity, the phrasing of questions, and receipt of feedback all affect the accuracy of eyewitness accounts.
