Study Notes
Neurotransmitters
- Dopamine: Involved in movement, attention, learning, and the brain's pleasure and reward systems.
- Serotonin: Influences hunger, sleep, arousal, and mood regulation.
- Acetylcholine: Critical for learning and memory; also initiates muscle contraction.
Research Studies
- Crockett et al. (2010): Study showed that elevating serotonin levels with citalopram led to a decrease in rejection of unfair financial offers (27-39% of total money), indicating increased acceptance of unfair proposals in subjects.
- Carhart-Harris et al.: Research indicates that LSD interacts with various neurotransmitter receptors, primarily affecting serotonin 2A receptors, leading to its psychological effects.
Concepts
- Ultimatum Game: A decision-making scenario where a proposer divides a sum of money with a responder, who can either accept or reject the offer; used to study fairness and negotiation strategies.
- Conceptually Triangulate: In research, it involves examining an issue from at least two distinct perspectives or points of view.
Brain Regions
- Prefrontal Cortex: Located at the frontmost part of the frontal lobes; essential for attention, working memory, decision-making, social behavior, and personality traits.
- Anterior Cingulate Cortex: Part of the anterior cingulate gyrus; important for the emotional response to pain.
Ethics
- Utilitarian Ethics: Evaluates actions based on their ability to maximize benefits for the greatest number of people, considering all relevant stakeholders.
