Study Notes
Psychology Definition and Approach
- Psychology is the scientific study of behavior and mental processes.
- It explores how individuals think, feel, and act, both individually and in groups.
- Psychology uses descriptive and explanatory approaches.
- Descriptive methods focus on observing and detailing characteristics (e.g., surveys, case studies).
- Explanatory methods aim to explain why and how behaviors occur (e.g., experiments).
Empirical Method
- Psychology relies on an empirical method, using observation, experimentation, and data analysis.
- This approach is grounded in measurable evidence.
- Wilhelm Wundt's 1879 Leipzig laboratory marked the first significant empirical use of psychological methods.
- He used introspection to investigate consciousness.
Key Figures in Psychology
- Wilhelm Wundt: Considered the "father of modern psychology" focused on structuralism.
- Structuralism aimed to break down mental processes into their most basic components.
- William James: Proposed functionalism.
- Functionalism emphasized the purpose of behavior and mental processes in adaptation to the environment.
Research and Methodology
- Non-scientific claims often rely on rationale and anecdotes.
- These approaches lack empirical evidence and can be misleading.
- Confirmation bias is a tendency to favor information supporting existing beliefs.
- Researchers must strive for objectivity and avoid confirmation bias.
- Dr. Abhijit Banerjee's work in development economics highlights how understanding decision-making psychology can advance poverty alleviation.
- A hypothesis is a testable prediction based on a theory.
- Falsifiability is a crucial aspect of research, allowing a theory or hypothesis to be proven false.
- A theory is a broad explanation of phenomena, subject to testing and refinement through research.
Research Approaches
- Inductive approach: Building theories from observations.
- Deductive approach: Testing existing theories through data analysis.
- Case studies: Provide in-depth understanding of individuals or groups, but may lack generalizability.
- Naturalistic observation: Studies behavior in natural settings, creating high ecological validity, but providing limited control over variables.
- Surveys: Useful for large sample sizes, but can suffer from response bias and misinterpretation of questions.
- Correlational research: Investigates relationships between variables, but cannot establish causation.
- Experiments: Involve manipulating an independent variable while controlling other factors.
- A true experiment involves manipulation of the independent variable, random assignment, and control of extraneous variables.
- An independent variable is manipulated to observe its effect on the dependent variable.
- A dependent variable is the variable measured to assess the effect of the independent variable.
- Peer-reviewed journal articles: Crucial for ensuring research credibility and quality.
Biopsychology and Neuroscience
- Nervous system: Composed of the central nervous system (CNS) and peripheral nervous system (PNS).
- CNS: Brain and spinal cord
- PNS: Connects CNS to the rest of the body, further subdivided into somatic and autonomic nervous system
- Somatic: Voluntary movement
- Autonomic: Involuntary functions
- Sympathetic: "Fight or flight" response
- Parasympathetic: "Rest and digest" response
- Neurons: Specialized cells transmitting electrical signals; including dendrites, axons, and the myelin sheath.
- Neurotransmitters: Chemical messengers influencing behavior (e.g., serotonin, dopamine, norepinephrine).
- Neurotransmitters carry messages between neurons influencing a variety of functions including mood regulation, reward, and arousal.
- Neuroplasticity: The brain's ability to adapt and reorganize its connections.
- Brain regions:
- Hindbrain: Basic functions (e.g., breathing, movement coordination).
- Midbrain: Sensory processing, movement.
- Forebrain: Higher cognitive functions.
- Cerebral cortex: Higher-order processes, divided into lobes.
- Frontal lobe: Motor control, planning, speech.
- Occipital lobe: Visual processing.
- Temporal lobe: Hearing, memory.
- Parietal lobe: Sensory information (touch, temperature).
- Cerebral cortex: Higher-order processes, divided into lobes.
- Endocrine system: Glands (e.g., pituitary) releasing hormones into the bloodstream.
