exam 3 Study guide Psychology Modules 19-28 Review
Module 19: Basic Learning and Classical Conditioning
Learning: A relatively permanent change in behavior due to experience.
Types of Conditioning:
- Classical Conditioning: Learning through association; involves pairing a neutral stimulus with an unconditioned stimulus (US) to elicit a conditioned response (CR).
- Operant Conditioning: Learning based on the consequences of behavior (reinforcements and punishments).
- Cognitive Learning: Involves understanding, knowing, or anticipating.
Key Concepts in Classical Conditioning:
- US (Unconditioned Stimulus): A stimulus that naturally triggers a response.
- UR (Unconditioned Response): The natural response to the US.
- CS (Conditioned Stimulus): A previously neutral stimulus that, after association with the US, comes to trigger a CR.
- CR (Conditioned Response): The learned response to the CS.
- Generalization: The tendency to respond similarly to stimuli that resemble the CS.
- Discrimination: The ability to distinguish between different stimuli.
Extinction and Spontaneous Recovery:
- Extinction: The diminishing of a CR when the CS is no longer paired with the US.
- Spontaneous Recovery: The reappearance of an extinguished CR after a rest period.
Module 20: Operant Conditioning
Shaping: Gradually guiding behavior toward the desired outcome through successive approximations.
Types of Consequences:
- Positive Reinforcement: Adding a pleasant stimulus to increase a behavior.
- Negative Reinforcement: Removing an aversive stimulus to increase a behavior.
- Positive Punishment: Adding an aversive stimulus to decrease a behavior.
- Negative Punishment: Removing a pleasant stimulus to decrease a behavior.
Primary vs. Conditioned Reinforcers:
- Primary Reinforcers: Innately satisfying, such as food or water.
- Conditioned Reinforcers: Stimuli that have acquired reinforcing properties through association with primary reinforcers.
Reinforcement Schedules:
- Fixed-Ratio: Reinforcement after a set number of responses.
- Variable-Ratio: Reinforcement after an unpredictable number of responses.
- Fixed-Interval: Reinforcement after a set time period.
- Variable-Interval: Reinforcement after varying time intervals.
Drawbacks of Physical Punishment:
- Can lead to aggression, avoidance, and does not teach appropriate behavior.
Module 21: Biology, Cognition, and Learning
Observational Learning: Learning by observing others, not through direct experience.
Bandura's Study:
- Focused on aggressive behavior, found that children imitate aggressive acts observed on media (Bobo doll experiment).
Mirror Neurons: Neurons that fire both when an animal acts and when it observes the same action performed by another.
Modeling Effects:
- Prosocial Modeling: Positive and constructive behaviors that can influence observers positively.
- Antisocial Modeling: Negative behaviors that can have harmful effects on observers.
Module 22-24: Memory
Key Terms:
- Encoding: The process of converting sensory input into a form usable in memory.
- Storage: The retention of encoded information over time.
- Retrieval: The process of accessing and bringing into consciousness information stored in memory.
Chunking: Grouping information into meaningful units to enhance memory.
Three Stages of Memory:
- Sensory Memory: Brief storage of sensory information.
- Short-term Memory: Limited capacity (7±2 items); lasts about 20-30 seconds without rehearsal.
- Long-term Memory: Potentially unlimited capacity; information can last from minutes to a lifetime.
- Iconic Memory: Visual stimuli.
- Echoic Memory: Auditory stimuli.
- Explicit Memory: Conscious memories of facts or events.
- Implicit Memory: Unconscious memories, such as skills.
Processing:
- Automatic Processing: Unconscious encoding of incidental information.
- Effortful Processing: Requires conscious effort and attention.
Serial Position Effect: Our tendency to recall best the last (recency effect) and first (primacy effect) items in a list.
Retrieval Influences:
- External contexts and internal emotions can significantly affect memory retrieval.
Memory Failures:
- Encoding Failure: Information never enters long-term memory.
- Decay: Memories fade over time if not accessed.
- Interference: Information can conflict with other memories.
- Retrieval Failure: Inability to access stored information.
Types of Interference:
- Proactive Interference: Older information interferes with new information.
- Retroactive Interference: New information impairs the retrieval of old information.
Memory Accuracy:
- Our memories can be distorted or influenced, evidenced by the misinformation effect (incorrect information alters memories) and source amnesia (forgetting the source of a memory).
Improving Memory: Techniques include the spacing effect (distributing study sessions), chunking, and minimizing interference when recalling information.
Module 25: Thinking
Module 26: Language
Language Definition: A system of communication using sounds, symbols, or gestures.
Receptive vs. Productive Language:
- Receptive Language: The ability to understand language.
- Productive Language: The ability to produce language.
Language Acquisition Theories:
- Skinner's Theory: Language is learned through operant conditioning.
- Chomsky's Theory: Children are born with an innate ability for language acquisition (theory of universal grammar).
Critical Period for Language Acquisition: Sensitive periods in development during which language acquisition occurs more easily. Questions exist whether animals possess language-like systems.
Modules 27-28: Intelligence
Definitions of Intelligence: Differ based on theorists:
- Spearman: General intelligence (g-factor) underlies all mental abilities.
- Gardner: Multiple intelligences (e.g., linguistic, logical-mathematical, etc.).
- Sternberg: Triarchic theory (Analytical, Creative, Practical intelligences).
Sternberg's Three Intelligences:
- Analytical: Problem-solving abilities akin to traditional IQ.
- Creative: Ability to adapt to new situations and formulate novel ideas.
- Practical: Skills in everyday tasks and real-world scenarios.
Origins of Intelligence Testing:
- Historical roots in early 20th-century France; involves calculating IQ based on mental age and chronological age (IQ = (Mental Age/Chronological Age) * 100).
IQ Score Differences: Research indicates potential gender and ethnic differences in average IQ scores, highlighting the influence of environment and culture on intelligence assessment.
