Emphasizes the evolutionary mechanisms that might help explain commonalities in language, learning, attention, perception, memory, sexual behavior, cooperation, helpfulness to others, emotion, and reasoning
Attempts to tease apart the relative contributions of heredity and environment to explain individual differences in personality, mental ability, and other characteristics
genetic make up for a trait
actual trait you display
a change in gene frequencies within a population over many generations
The evolutionary process in which individuals with genetically influenced traits that are adaptive in a particular environment tend to survive and reproduce in greater numbers
What are the 5 innate human characteristics
Interest in novelty
Desire to explore and manipulate
Impulse to play and fool around
Basic cognitive skills
A system that combines meaningless elements such as sounds or gestures to form structured utterances that convey meaning
the way a sentence is spoken
How a sentence is to be understood
Our ability to learn language is innate, but is also influenced by our experiences
True or False?
Interdisciplinary field that emphasizes evolutionary explanations of social behavior in animals
A statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals in a group
Intelligence is primarily the result of environmental influences rather than heredity.
True or False?
False, your intelligence is due to your genes
Measure of intelligence originally computed by dividing a person's mental age by his/her chronological age and multiplying by 100
Intelligence Quotient (IQ)
Intelligence scores of identical twins are always correlated more strongly than those of fraternal twins. True or False?
The scores of adopted children are strongly correlated with those of their biological parents. True or False?
Study the brain and the rest of the nervous system in order to gain a better understanding of behavior
Handles the central nervous system's input and output
Peripheral Nervous System
A collection of neurons and supportive tissue running from the base of the brain down the center of the back. Protected by the spinal column
What are the 2 structures located in the central nervous system?
Brain and spinal cord
All portions of the nervous system outside the brain and spinal cord, it includes sensory and motor nerves.
Peripheral Nervous System (PNS)
The subdivision of the PNS that connects to sensory receptors and to skeletal muscles
Somatic Nervous system
The subdivision of the PNS that regulates internal organs and glands
Autonomic Nervous System
The subdivision of the autonomic nervous system that mobilizes bodily resources and increases the output of energy during emotion and stress
Sympathetic Nervous System
The subdivision of the autonomic nervous system that operates during relaxed states and that conserves energy
Parasympathetic Nervous system
The brains communication specialists, transmitting information to, from, and within the central nervous system
A cell that conducts electrochemical signals; the basic unit of the central nervous system; also called the nerve cell
Provide the neurons with nutrients, insulate them, protect the brain from toxic agents, and remove cellular debris when neurons die. They also communicate chemically with other neurons.
What part of a neuron is tree-like or "branchy"?
Receive information from other neurons and transmit toward the cell body
Keeps the neuron alive and determines whether it will fire
Extending fiber that conducts impulses away from the body and transmits to other cells
A fatty insulation that may surround the axon of a neuron
A bundle of nerve fibers in the peripheral nervous system
The production of new neurons from immature stem cells
immature cells that renew themselves and have the potential to develop into mature cells
The site where transmission of a nerve impulse from one nerve cell to another occurs
A brief change in electrical voltage occurs between the inside and outside of an axon when a neuron is stimulated
Chemical released by a transmitting neuron at the synapse and capable of affecting the activity of a receiving neuron
The brain's ability to change and adapt in response to experience
