The nature-nurture debate explores the impact of genetics (nature) and environment (nurture) on human development.
Key Concepts: - Natural Selection: Process by which traits increase survival. - Evolutionary Psychology: Study of the mind through evolutionary theory. - Behavior Genetics: Exploration of genetic influences on behavior. - Heredity: Transmission of genetic characteristics.
Key Terms: - Genes: Units of heredity. - Genome: Complete set of genes in an organism. - Epigenetics: Study of changes in gene expression not involving alterations to the DNA sequence.
The nervous system consists of the central nervous system (CNS) and peripheral nervous system (PNS).
CNS: - Brain and Spinal Cord.
PNS: - Sensory Neurons (Afferent): Carry signals to the CNS. - Motor Neurons (Efferent): Carry signals from the CNS. - Interneurons: Connect neurons within the CNS.
Subdivisions: - Somatic Nervous System: Controls voluntary movements. - Autonomic Nervous System: Regulates involuntary functions (Sympathetic and Parasympathetic).
Neurons are the building blocks of the nervous system.
Structure: - Cell Body: Contains the nucleus. - Dendrites: Receive signals. - Axon: Transmits signals away from the cell body. - Myelin Sheath: Insulates the axon for faster transmission.
Key Processes: - Action Potential: Electrical signal that travels down the axon. - Synapse: Junction between neurons where neurotransmitters are released.
Chemical messengers that transmit signals across a synapse.
Key Terms: - Reuptake: Process of neurotransmitter reabsorption. - Endorphins: Neurotransmitters associated with pain relief and pleasure. - Agonist: Substance that activates a receptor. - Antagonist: Substance that blocks a receptor.
The endocrine system regulates physiological processes through hormones.
Key Aspects: - Hormones: Chemical messengers released into the bloodstream. - Psychoactive Drugs: Substances that affect brain function and behavior. - Substance Use Disorder: Condition characterized by an inability to control use of a substance.
The brain consists of multiple areas with distinct functions.
Main Sections: - Forebrain: Includes the cerebral cortex. - Midbrain: Controls auditory and visual processing. - Hindbrain: Manages vital functions (medulla, cerebellum).
Key Areas: - Limbic System: Involved in emotions and memory. - Cerebral Cortex: Responsible for higher mental processes (frontal, parietal, occipital, and temporal lobes).
Sleep is essential for physical and mental health.
Sleep Stages: - REM Sleep: Associated with dreaming. - NREM Sleep: Deep sleep stages. - Circadian Rhythm: Regulates sleep-wake cycles.
Disorders: - Insomnia: Difficulty in sleeping. - Narcolepsy: Sudden sleep attacks.
Several key figures have shaped our understanding of psychology and behavior.
Notable Individuals: - Sigmund Freud: Pioneer in dream analysis. - Roger Sperry: Research on split-brain phenomena. - Michael Gazzaniga: Furthered understanding of brain functionality.
