We’ll navigate the intricate sensory systems that allow us to perceive the world around us, unraveling the mechanisms by which our brains interpret and organize sensory information.

Biological Bases of Behavior

The biological bases of behavior explore the intricate relationship between our physical bodies and our psychological experiences. This includes understanding the structure and function of the nervous system, the role of neurotransmitters in transmitting signals between neurons, and the influence of genetics on our behavior and traits.

Structure and Function of the Nervous System

The nervous system is a complex network of specialized cells that transmits information throughout the body. It consists of two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).

• Central Nervous System (CNS):The CNS comprises the brain and spinal cord. It serves as the command center, processing information, making decisions, and controlling bodily functions.
• Peripheral Nervous System (PNS):The PNS consists of nerves that connect the CNS to the rest of the body. It carries sensory information to the CNS and motor commands from the CNS to muscles and glands.

Role of Neurotransmitters in Behavior

Neurotransmitters are chemical messengers that facilitate communication between neurons. They are released by presynaptic neurons and bind to receptors on postsynaptic neurons, triggering a response.

• Excitatory Neurotransmitters:These neurotransmitters increase the likelihood of firing in postsynaptic neurons. Examples include glutamate and acetylcholine.
• Inhibitory Neurotransmitters:These neurotransmitters decrease the likelihood of firing in postsynaptic neurons. Examples include GABA and glycine.

Genetics and Behavior

Genetics plays a significant role in shaping our behavior and traits. Genes carry instructions that determine our physical characteristics, but they also influence our psychological predispositions and responses.

• Twin Studies:Comparing the behavior of identical twins (who share 100% of their genes) and fraternal twins (who share 50% of their genes) can provide insights into the genetic basis of behavior.
• Genome-Wide Association Studies (GWAS):These studies scan the entire genome to identify genetic variants associated with specific traits or behaviors.

Sensation and Perception: Ap Psychology Unit 3 Vocab

Sensation refers to the process of receiving sensory information from the external world through our sense organs, while perception involves interpreting and organizing this information to create a meaningful representation of the world around us.

Our sensory systems include vision, hearing, smell, taste, and touch. Each system is specialized in detecting specific types of stimuli and converting them into electrical signals that are transmitted to the brain.

Vision

• Vision involves the detection of light by specialized cells in the retina of the eye.
