Study Notes
What is Psychology?
- Psychology is the study of behavior and mental processes.
- Psychologists describe, predict, explain and influence human actions and mental processes.
- Psychology was originally part of philosophy.
- Wilhelm Wundt founded the first psychology lab in 1879.
Theoretical Schools of Thought in Psychology
- Structuralism: Focuses on the structure and characteristics of the mind through introspection (Wilhelm Wundt and Edward B. Titchener).
- Functionalism: Focuses on how the mind works and its functions, understanding how behavior helps people adapt to their environment (William James).
- Psychodynamic: Focuses on the unconscious mind and its impact on human behavior (Sigmund Freud).
- Behaviorism: Focuses on observable behavior and how it is learned through conditioning (John B. Watson).
- Cognitivism: Focuses on mental processes such as thinking, memory, and language (George Miller & Ulric Neisser).
Research Methods in Psychology
- Naturalistic Observation: Observing behavior in a natural setting.
- Case Study: In-depth analysis of a single person or setting.
- Self-Report Measures and Surveys: Gathering data from individuals through questionnaires or interviews.
- Correlational Designs: Studying the relationship between variables.
- Experimental Designs: Studying cause-and-effect relationships through controlled experiments.
### Important Concepts In Research
- Population: The entire group of individuals that a researcher is interested in studying.
- Sample: A smaller group of people drawn from the population that participates in a study.
- Random Selection: Choosing participants from a larger population in such a way that everyone has an equal chance of being selected.
- Operational Definition: Translating a general research question into specific measurable procedures that can be observed.
### The Neuron
- Action Potential: A brief electrical charge that travels down a neuron, transmitting neural messages.
- Resting Potential: The neuron is polarized, with a negative charge inside and a positive charge outside.
- Depolarization: The neuron's gates open, allowing sodium ions (Na+) to rush in, reversing the charge.
- Repolarization: Potassium ions flow out, restoring the neuron's original charge.
- Refractory Period: A brief period of time where the neuron won't fire, no matter how much stimulation it receives.
### Neurotransmitters
- Chemical messengers that help neurons communicate with other neurons, muscles, and glands.
- Excitatory: Neurotransmitters that make it more likely that a neuron will fire.
- Inhibitory: Neurotransmitters that make it less likely that a neuron will fire.
- Agonist: Mimics or enhances the effect of a neurotransmitter.
- Antagonist: Blocks or impedes the normal activity of a neurotransmitter.
### The Autonomic Nervous System (ANS)
- Controls involuntary bodily functions (heart rate, breathing, digestion).
- Sympathetic Nervous System: "Fight or flight" response, preparing the body for action.
- Parasympathetic Nervous System: "Rest and digest" response, calming the body and restoring energy.
### The Polygraph
- Uses physiological measures linked to the ANS (galvanic skin response, heart rate) to detect deception.
### The Pituitary Gland
- Controlled by the hypothalamus.
- Releases hormones that influence growth, blood pressure, and other functions.
### Oxytocin
- The "love hormone" associated with child-mother attachment, maternal and romantic love, and trust.
### Sensation & Perception
- Sensation: receiving information from the environment
- Perception: interpreting and organizing sensory information to give it meaning
