Autobiographical Memory and Its Effects

Autobiographical Memory

• Autobiographical memories are detailed personal experiences, including sensory and emotional elements, tied to self-identity.
• These memories are rich with spatial, emotional, and sensory details.
• Autobiographical memories shape and reinforce self-concept by creating a narrative of life experiences.

The Reminiscence Bump

• The reminiscence bump is a tendency for people over 40 to recall more memories from adolescence and early adulthood.
• The self-image hypothesis suggests strong memory formation during this period due to identity development.
• High novelty in this period encourages stronger encoding of memories.
• The cultural life script hypothesis links strong memories to expected life milestones during this time.

Flashbulb Memories

• Flashbulb memories are vivid memories of surprising and significant events with strong confidence.
• Studies indicate these memories, despite confidence, are not always accurate; details can change over time.
• Emotional intensity activates the amygdala, enhancing memory encoding without guaranteeing accuracy.

Constructive Nature of Memory

• Memory is a reconstructive process, influenced by schemas and beliefs, leading to adjusted recollections.
• Bartlett's "War of the Ghosts" study showed how cultural expectations transform memories, adapting them to existing frameworks.

Source Monitoring and Source Misattribution

• Source monitoring involves determining memory origin (e.g., where did I learn this?).
• Source misattribution leads to errors in discerning memory origin, like mistaking heard or read information for actual experiences.

The Misinformation Effect

• The misinformation effect happens when post-event misleading information alters memory for the original event.
• Loftus' research demonstrated that wording changes (e.g., "smashed" vs. "hit") influence memory of events.
• This effect reveals memory's malleability and raises concerns for eyewitness testimony.

False Memories

• False memories are recollections of events that never happened or are misremembered.
• Suggestive questioning or visualization can implant false memories.
• The "Lost in the Mall" experiment showcased how easily false memories can be created through suggestion.

Emotion and Memory

• Emotional arousal during events strengthens encoding.
• The amygdala plays a critical role in forming emotional memories.
• Intense emotions lead to vivid memories, but these are still susceptible to distortion.
• Weapon focus affects memory accuracy by narrowing attention to a weapon during a crime.
