### The History of Psychology

Wilhelm Wundt, considered the father of experimental psychology, established the first experimental laboratory in 1879.
Wundt focused on studying conscious experiences, forming the basis of structuralism.
Structuralists aimed to uncover fundamental mental components of perception, consciousness, and other mental processes.
Functionalism emerged as a replacement for structuralism, emphasizing the mind's functions and the role of behavior in adaptation to the environment.

### Psychodynamic Perspective

This perspective views behavior as driven by unconscious inner forces beyond conscious control.

### Behavioral Perspective

Focuses on observable, measurable behavior, emphasizing the importance of external stimuli and responses.

### Cognitive Perspective

Employs the study of how people think, understand, and perceive the world.

### The Scientific Method

A systematic approach used by psychologists to acquire knowledge and understanding about behavior and related phenomena.
Four main steps:
- Formulate a hypothesis.
- Design a study.
- Collect and analyze data.
- Draw conclusions.
Theories provide broad explanations and predictions about phenomena of interest, serving as frameworks for understanding relationships between facts or principles.
Operational definitions translate hypotheses into specific, testable procedures that can be measured and observed in an experiment.

### Psychological Research

Descriptive research systematically investigates an individual, group, or patterns of behavior.
Four primary types of descriptive research methods include:
- Archival research, analyzing existing data from sources like census records, college records, and databases.
- Observational research, involving careful observations of naturally occurring behavior without manipulating the situation.
- Survey research, gathering information directly from individuals through surveys and questionnaires.
- Case studies, conducting in-depth investigations of a single individual or small group.
The double-blind procedure ensures the participant and the experimenter are unaware of the drug's properties, minimizing bias in assessing its effects.

### Genetics and Behavior

Genes are the biological "software" dictating the body's development, analogous to the "hardware."
Humans possess approximately 25,000 different genes.
Down syndrome, a cause of intellectual disability, occurs when a zygote receives an extra chromosome at conception.
The occurrence of Down syndrome is often linked to the mother's age, with higher rates among mothers over 35 and younger than 18.

### Prenatal Environmental Influences

Teratogens are environmental agents, including drugs, chemicals, viruses, and other factors, that can cause birth defects.
Mother's nutrition during pregnancy can significantly impact infant health.
Mother's illnesses, even mild ones during early pregnancy, can have severe consequences for a developing fetus.

### The Nervous System

The nervous system is composed of specialized and interconnected cells called neurons.
Neurons transmit messages in the form of electrochemical impulses.
Key parts of a neuron include:
- Dendrites, which receive messages from other neurons.
- Axon, which transmits messages to other neurons.
- Myelin sheath, a fatty coating that speeds up transmission.
- Synapse, the gap between neurons where neurotransmitters are released.

### Neurotransmitters: Chemical Couriers

Neurotransmitters are chemical messengers that transmit signals across synapses.
Different neurotransmitters fulfill specific roles:
- Acetylcholine (ACh), the most common neurotransmitter, is associated with muscle movements, memory, and Alzheimer's disease.
- Glutamate, a major excitatory neurotransmitter, is involved in learning and memory.
- Gamma-aminobutyric acid (GABA), the nervous system's primary inhibitory neurotransmitter, regulates brain activity.
- Dopamine (DA) plays a role in movement, attention, and learning.
- Serotonin is associated with sleep, eating, mood, and pain.
- Endorphins, a group of neurotransmitters, are similar in structure to painkilling drugs like morphine.

### The Central Nervous System

Composed of the brain and spinal cord, the CNS is the body's control center.
The spinal cord serves as a communication pathway between the brain and peripheral nervous system.
The brain controls various bodily functions, including thoughts, feelings, and behaviors.

### The Peripheral Nervous System

Branches out from the spinal cord and brain, reaching extremities.
Consists of neurons with long axons and dendrites.
Has two divisions: Somatic and Autonomic.
Somatic division controls voluntary movements and communicates with sense organs.
Autonomic division regulates involuntary processes like heart rate, breathing, and digestion.
Autonomic division has two sub-systems: Sympathetic and Parasympathetic.
Sympathetic division prepares the body for "fight or flight" in response to stress.
Parasympathetic division promotes relaxation and "rest and digest" functions.

### The Brain

The cerebrum is the largest part of the brain, responsible for higher-level functions like thinking, learning, and language.
The cerebellum is located at the back of the brain, plays a crucial role in coordination, balance, and motor skills.
The brainstem connects the cerebrum and cerebellum to the spinal cord, regulating basic functions like heart rate, breathing, and sleep.
The limbic system, located within the cerebrum, is involved in emotions, motivation, and memory.
The hippocampus is essential for learning and forming new memories.
The amygdala processes emotions, especially fear and aggression.
The hypothalamus regulates basic bodily functions like hunger, thirst, and body temperature.

### Neuroimaging Techniques

These techniques allow researchers to study the brain's structure and activity.
Electroencephalography (EEG) measures electrical activity in the brain using electrodes placed on the scalp.
Magnetic resonance imaging (MRI) provides detailed images of the brain's structure by using strong magnetic fields.
Functional magnetic resonance imaging (fMRI) measures brain activity by detecting changes in blood flow.
Positron emission tomography (PET) measures brain activity by using radioactive tracers.
