Study Notes
Founders and Theorists in Psychology
- Wilhelm Wundt established the first psychology laboratory in Germany; recognized as a physiologist and philosopher.
- Ivan Pavlov, a Russian physiologist, is known for pioneering the study of learning through classical conditioning.
- Sigmund Freud, an Austrian physician, developed theories on personality and the unconscious mind.
- Jean Piaget, a Swiss biologist, made significant contributions by observing children's behavior and cognitive development.
- William James, an American philosopher, authored "Principles of Psychology," the first textbook in psychology.
Definition and Concepts of Psychology
- Psychology is defined as the scientific study of behavior and mental processes.
- The Nature vs. Nurture debate addresses the roles of genetics (nature) and environment (nurture) in shaping behavior.
Psychological Perspectives
- Neuroscience examines how the brain and body interact.
- Psychodynamic theory focuses on unconscious drives influencing behavior.
- Behavioral psychology studies how responses are acquired and modified.
- Cognitive psychology involves how information is encoded, processed, stored, and retrieved.
- Social Cultural psychology investigates how behavior and thought differ across cultures.
Research Methods in Psychology
- Descriptive Research involves observing and describing behavior through case studies, surveys, or naturalistic observation.
- Correlation Research assesses statistical relationships between two variables (correlation does not imply causation).
- Positive correlation indicates a direct relationship.
- Negative correlation indicates an inverse relationship.
- Experimental Research manipulates variables to determine cause-and-effect relationships.
- Experimental group receives treatment; control group does not.
- Independent Variable (IV): factor manipulated; Dependent Variable (DV): behavior measured.
- Placebo effects can arise from participant expectations.
Critical Thinking and Experimental Design
- Critical thinking requires curiosity, open-minded skepticism, and humility.
- SQ3R method enhances learning by incorporating Survey, Question, Read, Retrieve, and Review stages.
Biological Foundations of Behavior
- Neurons are the basic units of the nervous system, processing and transmitting information.
- Dendrites receive information; axons transmit information; myelin sheath increases signal speed.
- Degeneration of myelin sheath can lead to conditions like Multiple Sclerosis (MS).
- Action potential is the electrical charge moving down an axon; synapses are gaps between neurons, where neurotransmitters act as chemical messengers.
Types of Neurons
- Afferent (Sensory) Neurons convey sensory information inward to the brain.
- Interneurons transmit signals within the brain and spinal cord.
- Efferent (Motor) Neurons send instructions outward to muscles and tissues.
Brain Function and Neurotransmission
- Neuroplasticity is the brain's ability to form new neural pathways in response to experiences.
- Agonists enhance neurotransmitter action; antagonists inhibit it.
- Endorphins create feelings of pleasure and pain relief.
Nervous and Endocrine Systems
- The Nervous System facilitates rapid electrochemical communication; the Endocrine System provides slower chemical signaling through hormones.
- Adrenal glands trigger fight-or-flight responses by releasing epinephrine; the pituitary gland regulates growth and releases oxytocin for social bonding.
Autonomic Nervous System
- Sympathetic Nervous System prepares the body for arousal (fight/flight); parasympathetic system promotes rest and digestion.
- The sympathetic system mobilizes energy, while the parasympathetic system conserves energy.
Key Psychological Terms
- Placebo: A non-active substance used in research to test treatment effects.
- Critical thinking in psychology is essential for evaluating claims and evidence.
