Study Notes
Classical Conditioning
- Conditioned Stimulus (CS): A previously neutral stimulus, after association with an unconditioned stimulus, triggers a conditioned response. (e.g., a bell in Pavlov's experiment).
- Unconditioned Stimulus (US): A stimulus that naturally triggers a response without prior conditioning. (e.g., food in Pavlov's experiment).
- Conditioned Response (CR): The learned response to the previously neutral stimulus. (e.g., salivation in response to a bell, after learning it signals food).
- Stimulus Generalization: Responding similarly to stimuli that are similar to the conditioned stimulus. (e.g., being afraid of all dogs after being bitten by one).
- Stimulus Discrimination: Learning to respond differently to similar stimuli. (e.g., a dog salivating only to a specific bell sound, not other sounds).
- Conditioned Tolerance: Reduced response to a drug when it is taken in the presence of cues associated with drug use. (Requiring more of a drug when taken in the environment where the person usually takes it).
- Systematic Desensitization: A therapeutic technique that involves gradual exposure to a feared stimulus while practicing relaxation techniques to reduce anxiety.
Operant Conditioning
- Positive Punishment: Adding an unpleasant stimulus to decrease a behavior. (e.g., getting a speeding ticket for speeding).
- Negative Reinforcement: Removing an unpleasant stimulus to increase a behavior. (e.g., fastening a seatbelt to stop the annoying beeping in a car).
- Positive Reinforcement: Adding a pleasant stimulus to increase a behavior. (e.g., giving a dog a treat for sitting).
- Negative Punishment: Removing a pleasant stimulus to decrease a behavior. (e.g., taking away a toy when a child misbehaves).
Neural Structures
- Sensory Neurons: Transmit sensory information from the skin, ears, eyes to the CNS.
- Motor Neurons: Send signals from the CNS to muscles, enabling movement.
- Interneurons: Facilitate communication within the CNS, connecting sensory and motor neurons.
- Relay Neurons: Transmit signals between different parts of the nervous system, helping coordinate responses.
Brain Regions
- Temporal Lobe: Responsible for auditory processing, memory formation, and language comprehension.
- Frontal Lobe: Involved in decision-making, planning, and voluntary movement coordination.
- Occipital Lobe: Specializes in visual processing and interpreting visual stimuli.
- Parietal Lobe: Integrates sensory information (touch, temperature, pain) & spatial awareness and navigation.
- Thalamus: Acts as a sensory relay station, processing and transmitting sensory information to the cerebral cortex.
- Hypothalamus: Regulates homeostasis, including hunger, thirst, temperature, and emotional responses.
- Medulla Oblongata: Controls vital autonomic functions (breathing, heart rate, blood pressure).
- Cerebral Cortex: Responsible for higher cognitive processes (thought, reasoning, voluntary actions).
Language Areas
- Broca's Area: Located in the left frontal lobe, responsible for speech production. Damage leads to Broca's aphasia.
- Wernicke's Area: Located in the left temporal lobe, involved in language comprehension. Damage leads to Wernicke's aphasia.
Theories of Sleep
- Deprivation Theory: Sleep deprivation impairs cognitive and physical health.
- Adaptive Theory: Sleep evolved as a survival mechanism to protect from predators and conserve energy.
- Immunology Theory: Sleep enhances immune function, and promotes healthy resilience.
- Restorative Theory: Sleep is crucial for the body to repair and rejuvenate from daily activities.
Sleep Disorders
- Narcolepsy: Episodes of uncontrollable sleep, often with cataplexy (loss of muscle tone).
- Sleep Apnea: Breathing interruptions during sleep.
- Epilepsy: Neurological disorder causing seizures.
- Hypnagogic Hallucinations: Vivid images or sensations during the transition from wakefulness to sleep.
- Paradoxical Sleep (REM): Active brain, but muscles paralyzed; dreams occur here.
- Restorative Sleep (NREM): Crucial for physical recovery and memory consolidation.
Psychology Basics
-
Levels of Analysis:
- Brain: Biological and neurological processes.
- Person: Individual behaviour, thoughts, mental processes.
- Group: Interpersonal interactions, relationships, dynamics.
- Culture: Social norms, values, beliefs, their impact on behaviour.
-
Goals of Psychology:
- Describe: Observe and document behavior, noting specific details.
- Explain: Understand and identify the causes of observed behaviour.
- Predict: Anticipate future behaviour.
- Control: Influence or change behavior.
-
Hypotheses:
- Null Hypothesis: Assumes no effect or relationship.
- Alternative Hypothesis: Predicts an effect or relationship.
Operational Definitions
- Specify variables clearly and precisely, using measurable terms. (Crucial for research clarity).
Variables
- Identified Variables: Key aspects being studied.
- Continuous Variables: Measured on a continuum (e.g., age).
- Dependent Variables: Outcomes affected by changes.
- Qualitative Variables: Non-numerical descriptions (e.g., emotions).
- Quantitative Variables: Numerical data (e.g., test scores).
Freud's Components
- Id: Instincts, pleasure principle.
- Ego: Reality principle, balancing Id & social constraints.
- Superego: Morality, ethical standards.
Archetypes & Personality Tests
- Jung Archetypes: Universal, symbolic representations in the collective unconscious.
- Rorschach Inkblot Test: Participants describe inkblots; reveals unconscious thoughts.
- Thematic Apperception Test (TAT): Participants create stories about ambiguous pictures; reveals motivations & emotions.
Minnesota Multiphasic Personality Inventory (MMPI)
- Comprehensive questionnaire assessing psychological traits and disorders.
OCEAN (Big Five Personality Traits)
- Measures five key personality traits (Openness, Conscientiousness/Conscientious, Extraversion, Agreeableness, Neuroticism).
