Nature vs. Nurture
The debate about whether genes or environment shape behavior.
What is the nature–nurture issue?
Neurons that carry messages from the body to the brain.
What are sensory neurons?
Behaviors that helped our ancestors survive and reproduce were passed down this way.
What is natural selection?
This division of the nervous system includes the brain and spinal cord.
What is the Central Nervous System (CNS)?
Comparing identical twins raised apart helps show the role of this.
What is genetics or heredity?
This modern view says both genes and environment shape behavior.
What is the interaction of nature and nurture?
Neurons that connect sensory and motor neurons within the CNS.
What are interneurons?
This explains why humans have fear of snakes or strangers.
What is an evolved survival behavior?
This division connects the CNS to the rest of the body.
What is the Peripheral Nervous System (PNS)?
Comparing adopted children to their adoptive parents shows the role of this.
What is environment?
This type of study shows how environment can influence gene expression.
What is epigenetics?
Chemicals that transmit signals across a synapse.
What are neurotransmitters?
This behavior, like forming friendships, helped humans survive and reproduce.
What is social behavior?
Neurons that carry messages from the CNS to muscles or glands.
What are motor neurons?
These studies help show how genes and environment interact to shape behavior.
What are twin and adoption studies?
