Study Notes
Cost of Anxiety
- Anxiety leads to physiological damage due to effects of adrenaline and cortisol.
- Opportunity costs arise from avoidance behaviors, limiting potential benefits.
- Sexual jealousy, as a mate-defending mechanism, increases vigilance against infidelity.
- Major survival benefit includes danger avoidance that prevents fatal outcomes.
- In some cases, anxiety may disrupt daily life, causing sleeplessness and distress.
Evolutionary Psychology Perspectives
- Costly traits may be adaptive evolutionarily but can create individual distress.
- Universal psychological mechanisms claimed by evolutionary psychology vary based on socio-ecological contexts.
- Psychological outputs, influenced by varying inputs, highlight the need for context-specific understanding.
Levels of Analysis in Evolutionary Psychology
- General Evolutionary Theory: Underpins evolution through natural selection.
- Middle-Level Theories, like Kin-Selection Theory, extend natural selection principles to altruism among closely related individuals.
- Specific hypotheses are derived from these middle-level theories, allowing researchers to predict psychological mechanisms.
Kin-Selection and Altruism
- Kin-Selection Theory explains genes' surrogacy through the advocacy of closely related individuals' reproduction.
- Examples include older siblings showing more altruism toward younger siblings due to kin-recognition mechanisms.
Decision Algorithms in Behavioral Responses
- Behavioral immune systems utilize probabilistic cues to trigger responses to pathogens.
- Example output includes disgust and avoidance behavior in reaction to perceived threats like corpses or feces.
Task Analysis and Adaptation Testing
- Essential to define specific design features to validate adaptations addressing adaptive problems.
- Clear specifications grant researchers the ability to create empirical studies to test adaptations.
- Detailed design allows researchers to conduct discriminative tests between alternative hypotheses.
Cost-Benefit Analysis
- Fitness costs and benefits associated with psychological outputs may differ depending on contextual factors.
- Analyzing these variations is key to understanding the adaptive significance of behaviors.
