Study Notes
Consciousness
- Definition: Subjective experience of the world, body, and mind.
- Altered States of Consciousness: Sleep paralysis, out-of-body experiences, near-death experiences, hypnosis, meditation, and drug-induced states.
Sleep
- What is Sleep?: Low physical activity and reduced awareness, associated with hormone secretion.
- Melatonin: Regulates sleep-wake cycle.
- Growth Hormone: Essential for development and repair.
- Follicle Stimulating Hormone and Luteinizing Hormone: Related to reproductive processes.
- Stages of Sleep (90-minute cycles)
- Stage 1: Brief period transitioning from wakefulness, slowed brain waves.
- Stage 2: Slowed brain waves further, sleep spindles and K-complexes (65% of total sleep).
- Stages 3 & 4: Delta waves dominate, growth hormone released, memory consolidation.
- Stage 5: REM Sleep: Rapid eye movements, vivid dreams, paralysis (brain active), REM rebound after deprivation.
Dreams
- Freudian Perspective: Dreams fulfill unconscious wishes (latent content), actual storyline (manifest content).
- Evolutionary Perspective: Dreams for survival, processing critical information.
- Neuroscience Perspective: Brain creates a story from random activity, emotional centers (limbic system) are active, prefrontal cortex is less engaged (Activation-Synthesis Theory).
Sleep Deprivation
- Effects: Increased stress, emotional overreactions, and impaired cognition, long-term cardiovascular and mental health issues.
- Peter Tripp "wakeathon": Resulted in hallucinations, paranoia, and personality changes.
- Prevention: Maintain a regular sleep schedule, quiet environment, and avoid caffeine before bed.
Psychoactive Drugs
- Types of Drugs:
- Stimulants: Increase arousal and energy (Caffeine, Nicotine, Amphetamines, Cocaine).
- Depressants: Slow down CNS activity (Barbiturates, Benzodiazepines, Alcohol, Opioids).
- Hallucinogens: Alter perceptions and sensory experiences (LSD, MDMA, Marijuana).
Drug Dependence
- Tolerance: Requires more of the drug for the same effect.
- Physical Dependence: Withdrawal symptoms occur without the drug.
- Psychological Dependence: Cravings to handle stress or emotions.
Key Concepts
- Sleep Paralysis: Occurs during REM transitions, linked to cultural influences.
- Circadian Rhythm: SCN and melatonin role.
- Dream Theories: Freud (wish fulfillment), Evolutionary (survival), Neuroscience (activation-synthesis).
- Psychoactive Drug Effects: Differentiate between stimulants, depressants, and hallucinogens.
Learning Basics
- Definition of Learning: A relatively permanent change in behavior or knowledge due to experience. Involves conscious and unconscious processes.
- Types of Learning:
- Habituation: Decreased response to a repeated stimulus.
- Sensitization: Increased response after repeated exposure to a stimulus.
Unlearned Behaviors
- Reflexes: Automatic, involuntary responses to stimuli (e.g., pupillary light reflex, startle reflex).
- Instincts: Innate drives or patterns of behavior (e.g., migration, sexual activity).
Classical Conditioning
- Overview: Learn to associate stimuli to anticipate events (Unconditioned Stimulus (UCS), Unconditioned Response (UCR), Neutral Stimulus (NS), Conditioned Stimulus (CS), Conditioned Response (CR)).
- Process: Acquisition, Extinction, Spontaneous Recovery, Stimulus Generalization, Stimulus Discrimination.
- Examples: Pavlov's dogs, Marketing (pairing products with appealing stimuli), Little Albert.
- Special Cases: Taste aversion, Fetishes.
Operant Conditioning
- Law of Effect: Behaviors followed by positive outcomes are more likely to recur.
- Key Components:
- Reinforcement (increases likelihood): positive (add pleasant stimulus), negative (remove unpleasant stimulus).
- Punishment (decreases likelihood): positive (add unpleasant stimulus), negative (remove pleasant stimulus).
- Issues with Punishment: Only teaches what not to do. Can cause anxiety or encourage sneaky behavior.
Schedules of Reinforcement
- Continuous Reinforcement: Reward every occurrence.
- Partial Reinforcement: Reward intermittently, slower learning, greater resistance to extinction.
Biological Influences on Learning
- Limits of Learning: Evolutionary predispositions (e.g., fear of snakes), Instinctive drift (revert to natural behaviors).
- Applications: Operant principles, partial reinforcement, abusive relationships.
Cognitive Approaches to Learning
- Latent Learning: Learning occurs without reinforcement and is demonstrated when needed (cognitive maps).
- Observational Learning: Learning by watching others (attention, retention, reproduction, motivation).
Media Violence and Learning
- Impact of Media: Frequent exposure to violence can lower inhibitions, distort perceptions and desensitize individuals, studies link violent video games to aggression and delinquency.
- Examples: Columbine shooters, children exposed to violent TV shows modeling aggressive behavior.
Memory
- Memory Misconceptions: Memory is reconstructive and dynamic, not a recording device.
- Three-Stage Model of Memory:
- Sensory Memory: Brief storage of sensory input (Iconic, Echoic).
- Short-Term Memory (STM): Temporary system (~30 seconds), 7 +/- 2 items.
- Long-Term Memory (LTM): Continuous, limitless storage.
- Working Memory: More dynamic version of STM, stores, and manipulates actively information, a 'mental whiteboard'.
- Types of Long-Term Memory:
- Declarative (Explicit): Conscious recollection (Semantic, Episodic).
- Nondeclarative (Implicit): Unconscious influence (Procedural).
- Neuroscience of Memory: Hippocampus (consolidation of declarative memory), Amygdala (emotional memories), Long-Term Potentiation (strengthening neural connections).
- Retrieval Failures: Decay, Interference.
- Encoding Failures: Lack of attention.
- False Memories: Fabricated through suggestion ("Lost in the Mall", Shaw & Porter).
- Memory Techniques: Levels of processing, effective methods for encoding specificity, context-dependent, state-dependent.
- Memory as Reconstructive: Schemas & Scripts. Stereotypes influencing recall; Suggestibility; Misinformation Effect.
- Amnesia: Anterograde (inability to form new memories), Retrograde (loss of pre-trauma memories).
Language, Thinking, and Reasoning
- Language: Communication through symbols, rule-based.
- Components: Phonemes (smallest sound units), Morphemes (smallest meaningful units), Syntax (rules for sentence construction).
- Language Acquisition & Development: Critical period (early in life), stages (babbling, first words, sentences), theories (learning, nativist, interactionist).
- Thinking: Manipulating mental representations, cognitive economy.
- Concepts: Mental categories (e.g., prototypes).
- Reasoning & Problem Solving: Algorithms, Heuristics, types (representativeness, anchoring).
- Framing Effects: Decisions influenced by how information is presented.
- Obstacles to problem solving: Mental sets, Functional fixedness, biases (confirmation bias, hindsight bias).
