Psychology Notes
1. Introduction to Psychology:
- Psychology is the scientific study of behavior and mental processes.
- It encompasses various subfields such as clinical psychology, cognitive psychology,
developmental psychology, social psychology, and more.
2. Schools of Thought:
- Structuralism: Focuses on the structure of consciousness and aimed to analyze sensations,
images, and feelings into basic elements.
- Functionalism: Emphasizes the functions and purposes of the mind and behavior in the
individual's adaptation to the environment.
- Behaviorism: Regards behavior as a response to stimuli in the environment and emphasizes
observable behavior rather than internal mental processes.
- Psychoanalysis: Developed by Sigmund Freud, emphasizes the role of unconscious conflicts
and early childhood experiences in shaping behavior and personality.
- Humanistic Psychology: Focuses on individual potential and stresses the importance of
growth and self-actualization.
3. Research Methods in Psychology:
- Experimental Method: Manipulates variables to establish cause-and-effect relationships.
- Correlational Method: Examines the relationship between two or more variables without
direct manipulation.
- Descriptive Method: Observes and records behavior without manipulating variables.
- Case Studies: In-depth examination of an individual or small group.
- Surveys: Collect data from a large sample through self-report measures.
- Ethical Considerations: Informed consent, confidentiality, avoiding harm, debriefing, etc.
4. Biological Bases of Behavior:
- Neurotransmitters: Chemical messengers that transmit signals across synapses between
neurons.
- Central Nervous System (CNS): Brain and spinal cord, responsible for processing
information and generating responses.
- Peripheral Nervous System (PNS): Nerves connecting the CNS to the rest of the body,
including sensory and motor neurons.
- Endocrine System: Consists of glands that secrete hormones into the bloodstream,
influencing behavior and physiology.
5. Sensation and Perception:
- Sensation: Process by which sensory receptors detect and transmit information to the brain.
- Perception: Process of organizing and interpreting sensory information to give it meaning.
- Sensory Adaptation: Decrease in sensitivity to a constant stimulus over time.
