1. What is Psychology?
Psychology is the scientific study of behavior and mental processes.
Historical Origins:
● Early thinkers like Aristotle laid the foundation, but Wilhelm Wundt is known as the first
psychologist.
● Structuralism: Focused on the structure of the mind (Wundt and Titchener).
● Functionalism: Focused on the function of mental and behavioral processes (James).
Evolution of Psychological Thought:
● Behaviorism: Focus on observable behaviors (Watson, Skinner).
● Humanistic Psychology: Emphasis on personal growth and self-actualization (Rogers, Maslow).
● Cognitive Revolution (1960s): Renewed interest in mental processes like thinking and memory.
Subfields of Psychology:
● Clinical Psychology: Diagnosing and treating mental illness.
● Counseling Psychology: Helping with everyday life issues.
● Educational Psychology: Studying learning and teaching.
2. Research Strategies: How Psychologists Ask and Answer Questions
Psychologists use the scientific method to explore behavior and mental processes.
Key Research Methods:
● Case Studies: In-depth analysis of individuals or small groups.
● Naturalistic Observation: Observing behavior in natural environments.
● Surveys: Gathering self-reported data from many people.
● Experiments: Manipulating variables to identify cause-and-effect.
Ethical Considerations:
● Informed Consent: Participants must know what the study involves.
● Voluntary Participation: No coercion allowed.
● Protection from Harm: Researchers must minimize risk.
● Confidentiality: Participants' data must be kept private.
● Debriefing: Participants must be told the study’s purpose afterward.
3. Statistical Reasoning for Everyday Life
Statistics help summarize and interpret data.
, ● Descriptive Stats: Mean, median, mode.
● Standard Deviation: Measures variation.
● Correlation Coefficient (r): How closely two things relate.
● Important Note: Correlation ≠ Causation.
4. Neural and Hormonal Systems
Biological Basis of Behavior:
● Neurons: Basic units of the nervous system that transmit signals.
● Glial Cells: Support neurons by providing nutrients and cleaning up waste.
● Neurotransmitters: Chemical messengers that cross synapses.
● Endocrine System: Glands that secrete hormones into the bloodstream.
5. Tools of Discovery, Older Brain Structures, and the Limbic System
● EEG, PET, MRI, fMRI: Techniques to observe brain activity.
● Brainstem: Controls basic functions like breathing and heartbeat.
● Thalamus: Directs sensory messages.
● Cerebellum: Coordinates movement and balance.
● Limbic System: Involved in emotion and memory; includes amygdala, hippocampus, and
hypothalamus.
6. The Cerebral Cortex
● Frontal Lobes: Planning, reasoning, movement.
● Parietal Lobes: Sensory input and spatial reasoning.
● Occipital Lobes: Visual processing.
● Temporal Lobes: Auditory information.
● Motor Cortex: Controls voluntary movement.
● Sensory Cortex: Processes touch and body sensations.
10. Behavior Genetics: Predicting Individual Differences
● Behavior genetics explores the influence of genes and environment.
● Twin Studies: Compare identical and fraternal twins.
● Heritability: Proportion of trait variation due to genes.
● Genes and environment interact to shape traits.
