Research Methods in Psychology

• Descriptive Methods: These methods, like case studies and naturalistic observation, aim to provide a detailed picture of a phenomenon. They do not establish cause-and-effect relationships.
• Correlational Methods: Used to measure how strongly two variables are related. They do not prove causation.
• Experimental Methods: Most powerful tools in psychology for determining cause-and-effect relationships. Manipulating one variable (independent variable) to see its effect on another (dependent variable).
• Types of Measurements and Data Collection: Observation (structured and unstructured), questionnaires, interviews and various psychological tests.

The Human Nervous System

• Brain Structure and Function: The brain consists of various regions with specialized functions, including the cerebrum, cerebellum, and brainstem.
• Neurons and Neurotransmitters: The brain is composed of neurons that communicate with each other through electrochemical signals. Neurotransmitters are chemical messengers that transmit signals between neurons.
• Divisions of the Nervous System: The nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS connects the CNS to the rest of the body.
• Hormonal System: The endocrine system interacts with the nervous system through hormones.

Cognitive Processes

• Perception: The process of organizing and interpreting sensory information.
• Attention: The ability to focus on specific stimuli while filtering out distractions.
• Memory: The ability to encode, store, and retrieve information.
• Language: The ability to communicate using symbolic systems.
• Problem-solving: The process of finding solutions to complex issues.

Emotional Processes

• Basic Emotions: Emotions such as joy, sadness, anger, fear, surprise, and disgust.
• Emotional Regulation: The process of managing and controlling one's emotions.

Motivation

• Biological Motives: The basic needs of survival, such as hunger, thirst, and sleep.
• Psychological Motives: Individual needs for self-esteem, achievement, or affiliation.

Developmental Psychology

• Cognitive Development: Studies how thinking processes change across the lifespan.
• Social-Emotional Development: Studies how social interactions and emotions develop in individuals.
• Physical Development: Studies changes in the body over the life span.

Social Psychology
