Study Notes
Brain Size and Cognition
- The cephalization index enables comparison of brain size relative to body size among species.
- Caution is required when interpreting brain size as an indicator of intelligence due to other influencing factors.
- Birds possess compact brains to reduce weight for flight, while dolphins have larger brains in buoyant aquatic environments.
- Not all brain parts contribute to cognitive functions; for instance, the hindbrain regulates basic physiological processes.
Logical Reasoning and Heuristics
- Different problem presentations can affect perceived difficulty despite identical logical structures.
- Example scenarios:
- Clerk scenario requires checking E-rated documents against their codes.
- Bouncer scenario checks if vodka drinkers meet age requirements.
- Heuristics simplify problem-solving but can induce errors, leading to fallacies based on probabilities.
- The representativeness heuristic causes misjudgment based on perceived similarities rather than statistical reality.
Tversky and Kahneman's Research
- Tversky and Kahneman explored heuristics and biases, demonstrating how people misjudge probabilities.
- Example study illustrated participants' bias in identifying a person based on stereotypical traits rather than base rates.
- The base-rate fallacy shows a common oversight in integrating overall statistical information while making judgments.
Evolutionary Perspective on Judgments
- Evolutionary experiences shape judgments under uncertainty; the gambler’s fallacy arises from a misunderstanding of odds, influenced by natural cycles.
- Humans often anticipate alternating events based on past occurrences, affecting their beliefs about future outcomes.
Language and Cognition
- Language's significance in cognitive science is recognized, with linguistics focusing on its structure and acquisition.
- Unlike other species, humans exhibit advanced language use, underlying unique aspects of social structures and interaction.
- Cultural rather than genetic factors may explain observed sex differences in linguistic skills among children and adults.
Evaluating Evolutionary Psychology
- Evolutionary psychology (EP) is a recent field emphasizing a unified theoretical approach to human behavior based on evolutionary principles.
- It strives to integrate various psychological disciplines, such as cognitive and developmental psychology.
- Critiques arise from within the evolutionary framework, challenging assumptions about the adaptiveness of psychological mechanisms.
- Exaptation and neutral drift are alternative concepts explaining biological functions beyond mere survival and reproduction responses.
