Study Notes
Research Variables
- Independent Variable: The variable manipulated by researchers, e.g., temperature affecting moods.
- Dependent Variable: The outcome being measured, e.g., moods influenced by temperature.
- Extraneous Variable: External factors that can affect the dependent variable, e.g., noise disrupting mood experiments.
- Experimental Group: Participants receiving the treatment in a study, e.g., students taught with a new method.
- Control Group: Participants not receiving the treatment, used for comparison, e.g., students taught with the old method.
- Random Assignment: Randomly placing participants into groups reduces bias and ensures valid comparisons.
Objectives of Psychology
- Understand Behavior: Explore psychological, biological, social, and environmental influences on behavior.
- Predict Behavior: Anticipate when and how behaviors will recur based on past observations.
- Control Behavior: Alter behaviors to encourage positive outcomes or discourage harmful actions.
Early History of Psychology
- Greek Philosophers: Aristotle's exploration of sleep, senses, dreams, and memory laid foundational concepts around 300 BC.
- Rene Descartes: Proposed dualism, suggesting mind and body are separate entities; contrasts with monism, which asserts a singular existence.
- Nature vs. Nurture Debate: Explores whether traits are innate or influenced by the environment.
William James and Functionalism
- William James: Father of American psychology and founder of functionalism, focuses on why mental processes exist and their role in adaptation.
- Purpose Over Structure: Emphasizes understanding mental activities based on their function in adapting to the environment.
John B. Watson and Behaviorism
- Behaviorism: Emerged in the early 1900s, concentrating on observable behavior rather than consciousness.
- Major Proponents: Includes figures like B.F. Skinner, Ivan Pavlov, Edward L. Thorndike, and Albert Bandura.
- Learning Through Environment: Assumes all behaviors are learned from interactions with the environment.
Sigmund Freud and Psychoanalysis
- Psychoanalysis: Focuses on unconscious influences on behavior, emphasizing early childhood experiences and internal conflicts.
- Freud’s Contributions: Highlights the role of unconscious drives in shaping personality and behavior.
Research Methodologies
- Experimental Research: Allows replication, enhancing validity; focuses on independence and dependence of variables while recognizing ethical limitations.
- Correlational Research: Studies relationships between variables without manipulation; identifies positive, negative, or no correlations.
Branches of Psychology
- Clinical Psychology: Focuses on diagnosing and treating mental disorders.
- Health Psychology: Examines how psychological factors impact health and encourages healthier behaviors.
- Experimental Psychology: Uses scientific methods to study human thoughts and behavior.
- Social Psychology: Investigates how social interactions influence thoughts, feelings, and behaviors.
Key Takeaway
- Psychology is a multifaceted discipline with various approaches to understanding behavior, influenced by historical figures and diverse branches aimed at addressing different aspects of human experience.
