Study Notes
Introduction to Psychology
- Psychology is a scientific study of the mind and behavior, not just mental health.
- It's a constantly evolving field, with ongoing research.
- Psychology includes helping people, conducting research, and teaching.
Philosophical Roots of Psychology
- Dualism: The mind and body are separate entities.
- Materialism: Everything is explained by physical processes, including thoughts.
- Realism: Reality exists independently of perception based on facts.
- Idealism: Reality is shaped by ideas and imagination.
- Nativism: Certain abilities and knowledge are innate.
- Empiricism: Our abilities come from experience and learning.
- Free Will: The power to choose actions.
- Determinism: Actions are influenced by factors like genetics, environment, or past events.
History of Psychology
-
1800s:
- Structuralism: Analyzed the mind through introspection and lab experiments.
- Functionalism: Studied the purpose of mental processes through observation, influenced by natural selection.
- 1900s: Focused on observable behaviors (behaviorism).
- Late 1900s: Focused on mental processes and evolutionary psychology.
-
2000s:
- Neuroscience became prominent, examining brain activity.
- Cross-cultural psychology explored how culture impacts the mind.
Methods in Psychological Science
- Psychology relies on empirical data (observations and experiments).
- Scientific Method: Identify, gather, test, analyze, and build theories to reduce bias.
- Fact: Agreed-upon truth based on observations.
- Hypothesis: Testable prediction.
-
Theory: Explains why or how something happens.
- Good theories are comprehensive, testable, simple (Occam's Razor), and generative.
-
Defining Variables:
- Conceptual Definition: Explains the meaning of a concept.
- Operational Definition: Describes how a concept is measured.
-
Gathering Data:
-
Self-Report: Surveys or interviews.
- Pros: Easy.
- Cons: Honesty can be a concern.
-
Behavioral Observation: Watching and recording actions.
- Pros: Captures natural behavior.
- Cons: Participants' awareness might affect behaviour.
-
Physiological Measures: Using tools like heart monitors or brain scans.
- Pros: Difficult to fake.
- Cons: Interpretation needs context (e.g., fast heart rate from anxiety or caffeine).
-
Self-Report: Surveys or interviews.
-
Psychological Tests:
- Self-Report: People share details about themselves.
- Projective Tests: Uses ambiguous images to reveal feelings.
- Performance-Based Tests: Assessing abilities/traits.
Research Designs
- Descriptive Research: Observes and describes behavior (case studies, observation, surveys).
- Correlational Research: Examines relationships between variables without proving cause and effect (correlation coefficient: strength and direction).
-
Experimental Research: Tests causation by manipulating variables.
- Independent Variable: Changes or controlled.
- Dependent Variable: Measured to see the effect.
- Control Group: No treatment.
- Experimental Group: Receives the treatment.
Ensuring Quality in Research
- Reliability: Consistency of results (test-retest, inter-rater, internal consistency).
-
Validity: Accuracy of measurement.
- Face Validity: Appears to measure what it's meant to.
- Content Validity: Covers all aspects of the concept.
- Convergent Validity: Correlates with similar measures.
- Discriminant Validity: Doesn't correlate with unrelated measures.
Statistics in Psychology
- Descriptive Statistics: Summarizes data (mean, median, mode).
- Inferential Statistics: Draws conclusions about populations from samples.
Language and Thought
- Language has structure (phonemes, morphemes, words, phrases, sentences).
- Bilingualism: Learning multiple languages has benefits, especially during childhood (0-7 years).
-
Brain and Language:
- Broca's Area: Speech and sentence formation.
- Wernicke's Area: Understanding speech.
Schemas and Thought
- Schemas: Mental frameworks organizing knowledge.
- Scripts: Schemas for specific events (restaurant experience as an example).
-
Reasoning:
- Inductive: Creating theories from observations.
- Deductive: Testing theories with specific cases.
Intelligence
- Intelligence is the ability to adapt, learn, and solve problems.
-
Types:
- Crystallized Intelligence: Knowledge from experience (increases with age).
- Fluid Intelligence: Problem-solving and adaptation (peaks in early adulthood).
