Chapter 1 Flashcards
Define Biological Psychology.
Biological Psychology is the study of the physiological, evolutionary, and developmental mechanisms of behavior and experience.
What is the view of the human brain from the top called?
A Dorsal View.
What is the view of the human brain from the bottom called?
A Ventral View.
At the microscopic level of the brain, what are the 2 kinds of cells found called?
The neurons and the glia.
In contrast to common-sense explanations, biological explanations of behavior fall into what 4 categories?
Physiological, Ontogenetic, Evolutionary and Functional.
Define what a Physiological Explanation is.
A physiological explanation relates a behavior to the activity of the brain and other organs. It deals with the machinery of the body – for example, the chemical reactions that enable hormones to influence brain activity and the routes by which brain activity controls muscle contractions.
Define what an Ontogenetic Explanation is.
The term ontogenetic comes from the Greek roots meaning the origin (or genesis) of being. An ontogenetic explanation describes how a structure or behavior develops, including the influences of genes, nutrition, experiences, and their interactions. For example, the ability to inhibit impulses develops gradually from infancy through the teenage years, reflecting gradual maturation of the frontal parts of the brain.
Define what an Evolutionary Explanation is.
An evolutionary explanation reconstructs the evolutionary history of a structure or behavior. For example, frightened people get “goose bumps” – erections of the hairs, especially on their arms and shoulders. Goose bumps are useless to humans because our shoulder and arm hairs are so short. In most other mammals, however, hair erection makes a frightened animal look larger and more intimidating. An evolutionary explanation of human goose bumps is that the behavior evolved in our remote ancestors and we inherited the mechanism.
Define what a Functional Explanation is.
A functional explanation describes why a structure or behavior evolved as it did. Within a small, isolated population, a gene can spread by accident through a process called genetic drift. For example, a dominant male with many offspring spreads all his genes, including neutral and harmful ones. However, a gene that is prevalent in a large population presumably provided some advantage – at least in the past, though not necessarily today. A functional explanation identifies that advantage.
How does an evolutionary explanation differ from a functional explanation?
An evolutionary explanation states what evolved from what. For example, humans evolved from earlier primates and therefore have certain features that we inherited from those ancestors, even if the features are not useful to us today. A functional explanation states why something was advantageous and therefore evolutionarily selected.
Define dualism.
Dualism is the belief that mind and body are different kinds of substance that exist independently.
What is the name of the french philosopher who defended dualism?
Rene Descartes
What is the main reason nearly all scientists and philosophers reject the idea of dualism?
Dualism contradicts the law of conservation of matter and energy. According to that law, the only way to influence matter and energy, including that of your body, is to act on it with other matter and energy.
Define the alternative to dualism, monism.
Monism is the belief that the universe consists of only one kind of substance.
What are the 3 categories of monism called?
Materialism, Mentalism, and Identity Position.
