Biological Explanations of Behavior Flashcards
Behaviors that require us to think about why a person acts.
Biological Explanations of Behavior
It falls into the “commonsense” or “want to” category.
Normal Behavior
Focuses on the behavior of certain parts of your brain and other organs.
Physiological Explanations
It covers cellular, chemical, and hormonal reactions or influences.
Physiological Explanations
Relation of behavior to brain activity and other organs.
Physiological Explanations
It explains why or how a behavior evolved the way it did.
Functional Explanations
What are its purpose and genetic/survival advantage.
Functional Explanations
It is the development of behavior or structure.
Ontogenetic Explanations
It influences nutrition, genes, experiences, and interactions in regard to the development of that certain behavior.
Ontogenetic Explanations
It comes from the word ‘ontogeny’ meaning changes and development of an individual.
Ontogenetic Explanations
It comes from the word ‘phylogeny’ meaning the evolutionary history of behavior or structure.
Evolutionary Explanations
Certain behavior or structure have evolved over time because they have solved certain problems that improved their reproductive capability showing that feature (adaptability).
Evolutionary Explanations
relates a behavior to the activity of the brain and other organs
Physiological Explanations
describes the development of a structure or behavior including the influences of genes, nutrition, and experiences
Ontogenetic Explanations
reconstructs evolutionary history of a behavior or structure
Evolutionary Explanations
describes why a structure or behavior evolved as it did
Functional Explanations
This tries to answer how a particular behavior has evolved.
Functional Explanations
Some species can change the color of their skin to match their surroundings, the functional significance of this ability to hide from predators is obvious.
Functional Explanations
We thus need to understand the natural history of a species, so that the behaviors can be seen in the correct context.
Functional Explanations
This examines a structure or behavior in terms of the evolutionary history of the species (‘phylogeny’)
Evolutionary Explanations
Certain physical and behavioural features have emerged over evolutionary time because they have solved certain problems in a way that have improved the reproductive capability of the individual showing that feature (they are ‘adaptive’).
Evolutionary Explanations
When certain species of animals are threatened, they respond by erecting their body hairs making them look bigger and more intimidating (piloerection).
Evolutionary Explanations
When humans are frightened they also erect their body hairs, but as humans have lost most of their body hair this results in the sensation known as goose bumps.
Evolutionary Explanations
Raise the issue of the relationship between mental activity and the brain also know as the “mind-body” or “mind-brain problem”
