Flashcards
Adaptation
Adaptation
A feature or trait that helps an organism survive and reproduce better in its environment. It's developed over time through evolution.
Disgust
Disgust
A strong feeling of dislike or revulsion. It evolved to help us avoid things that could harm us, like contaminated food or disease.
Evolution
Evolution
The process of change in species over many generations. It happens because traits that help survival and reproduction are passed on more often.

Study Notes
Evolutionary Psychology
- Adaptation: A trait improving survival or reproduction in an environment.
- Disgust: Strong dislike triggered to avoid harm (e.g., spoiled food, disease).
- Evolution: Species change over time due to inherited trait variations.
- Massive Modularity: The brain has specialized parts (modules) for specific tasks.
- Natural Selection: Surviving and reproducing organisms pass traits to offspring.
- Post-Hoc Reasoning: Explaining events after they happen, often biased.
- Fessler et al. (2005): Studied disgust sensitivity during pregnancy.
- Aim: To see if disgust sensitivity increases during early pregnancy.
- Procedure: Surveyed pregnant women about disgust responses, focusing on food.
- Findings: Highest disgust sensitivity in first trimester, especially for food. This supports the idea that disgust evolved to protect against disease during pregnancy when the immune system is potentially compromised.
- Strengths: Large sample size. Focused on evolutionary mechanism.
- Limitations: Self-reported data may be biased. Limited to a specific culture.
Neurotransmitters and Behavior
- Agonist: Mimics signal ligand, activating the receptor.
- Antagonist: Binds to the receptor to prevent activation by agonists.
- Neurotransmitter: Chemical messengers between neurons, muscles, and glands.
- SSRI: Antidepressant drug that boosts serotonin availability by inhibiting reuptake.
- Crockett et al (2010): Studied serotonin's effect on moral decision-making.
- Aim: To see how serotonin increase affects moral judgments.
- Procedure: Double-blind experiment with participants given either a serotonin-boosting drug or a placebo. Participants faced moral dilemmas (utilitarian choice scenarios).
- Findings: Participants given serotonin were less likely to choose harmful actions even for the benefit of the overall group. This suggests serotonin correlates positively with prosocial behavior and avoidance of harm.
- Strengths: Controlled experiment. Explores the biological underpinnings of morality.
- Limitations: Small sample size, impacting generalizability. The artificial tasks may not fully reflect complex real-life moral judgments.
