PERSONAL IDENTITY AND MEMORY

  • Locke's Theory:

    • A person at time t is the same as at an earlier time t if they can remember experiences of that individual.

  • Reid's Critique:

    • Memory criterion is circular; it assumes personal identity.

    • One can only remember events that happened to them.

  • Schechtman's Two Questions:

    • Reidentification Question: Is an individual the same at different times?

    • Characterization Question: Which mental states/attitudes and actions define a person?

MEMORIES, THE SELF, AND ALTERATIONS

  • Although Locke's thesis may be incorrect, memories are integral to identity.

  • Considerations:

    • If we lost our memories, would we still be the same person?

  • Quote:

    • "I am the sum of my plans and policies..."

  • Neuroscience Implications:

    • Potential to alter memory systems:

      • Deliberately deleting memories.

      • Inserting false memories.

      • Enhancing memory capacities.

TOTAL RECALL

  • Challenges in Implanting Memories:

    • Technical Obstacles:

      • Understanding how memories are stored and retrieved.

      • Mimicking these processes artificially.

    • Holism of Mental Content:

      • Mental content is interconnected with other meaningful concepts.

  • Example:

    • If Patty is implanted with a false memory of a Disneyland trip with a non-existent brother, she must also recall the existence of the brother for cohesive memory retrieval and endorsement.

FALSE MEMORIES

  • Loftus' Experiments:

    • People recall faster speeds when primed with "smashed" vs. "hit".

    • Misleading information leads to inaccuracies in personal recollections.

    • Entire fabricated memories were created in 1/3 of subjects.

  • Witness Reliability Issues:

    • The DC sniper case showed how media influence can skew public memory.

FALSE MEMORIES AND PERSONAL IDENTITY

  • Case of Flanagan:

    • False memory of a childhood friend ('Billy') gave confidence to make new friends.

    • This memory was artificially constructed, having only known a Billy once.

  • Value of False Memories:

    • Some false memories can aid self-knowledge, helping understand abilities.

    • Example: Erasing the memory of a failed stand-up performance could hinder personal growth.

HARM PRINCIPLE, NARRATIVE AND RECOGNITION

  • Mill's Harm Principle:

    • Right to act as one chooses, provided it doesn't harm others.

  • Memory Erasure Context:

    • Permissible if it harms only the consenting individual.

  • Impact on Personal Narrative:

    • Erasure might affect one's identity and relationships, leading to feelings of disconnection.

  • Recognition:

    • Important for social animals; loss of memories can lead to an identity crisis (e.g., children being forgotten).

PTSD AND MEMORY MODERATION

  • Mitigation Tactics:

    • Preventing a traumatic event.

    • Preventing PTSD post-event through memory consolidation management.

  • Propranolol Usage:

    • Beta-blocking to manage stress hormones and symptoms of PTSD after the fact.

SOMATIC MARKER HYPOTHESIS (SMH)

  • Emotions in Decision Making:

    • SMH posits emotional arousal can enhance rather than detract from decision-making.

  • Iowa Gambling Task:

    • Subjects preferred better long-term decks before understanding outcomes, indicated by anticipatory skin conductance responses (SCRs).

  • Neural Impacts:

    • Patients with damage to the ventromedial prefrontal cortex lacked anticipatory SCRs, leading to poor choices.

SOMATIC MARKER HYPOTHESIS CONTINUED

  • Childhood Damage Consequences:

    • Early congenital damage can present psychopathic traits later.

  • Emotional Influence on Morality:

    • Manipulating somatic responses can impact moral evaluations significantly.

  • Connections to PTSD:

    • Propranolol's effects on amyloid receptors could disrupt moral judgements alongside managing PTSD.

TROLLEY PROBLEM, PROPANOL, AND ‘HOT’ JUDGMENTS

  • Moral Dilemma:

    • Contrasting intuitive responses to saving many lives versus harm to an individual.

  • Evolutionary Perspective:

    • Personal engagement affects moral responses differently based on evolutionary history.

  • Propranolol Research:

    • Still inconclusive about its effectiveness in preventing PTSD.

SUPER SOLDIERS ON PROPANOL — CONCLUSION

  • Potential Military Application:

    • Administering Propranolol to soldiers before combat may reduce PTSD risks.

  • Ethical Concerns:

    • May diminish moral compass via elimination of somatic signals indicating wrongness.

  • Summary:

    • Memory modification is complicated by the holism of memory and emotional implications, necessitating careful ethical considerations in application.
