Study Notes

Memory

Attention is vital for encoding memories
Deeper processing leads to longer-lasting memories
Visual imagery can enhance encoding
Memory is better for words linked to the self
The serial position effect describes the tendency to remember words at the beginning (primacy effect) and end (recency effect) of a list.
Sensory memory holds a brief copy of what is seen or heard (icons for visual, echo for auditory).
Short-term memory lasts for about 10 seconds and is very sensitive to interference and decay.
Working memory is short-term memory combined with other mental processes, where most thinking occurs.
Long-term memory has an unlimited capacity and holds information for extended periods.
- Declarative memory stores factual information.
  - Semantic memory: General knowledge
  - Episodic memory: Personal experiences
- Procedural memory stores memory for actions and skills
Retrieval cues can jog memories.
Context is a useful retrieval cue.
Forgetting can occur due to failure to encode information, interference, decay, or retrieval failure.
Multiple choice tests are recognition measures of retention.
Essay exams are recall measures of retention.
Clive Wearing experienced severe memory impairment, unable to form new memories. He had anterograde amnesia and retrograde amnesia.

Learning

Learning is a relatively permanent change in behavior due to experience.
Behaviorism focuses on observable behavior, not mental processes.
Associative learning links two events that occur close in time.
- Conditioning is the process of learning associations.
- Classical conditioning is an association between two stimuli, anticipating a physiological response.
- Operant conditioning is an association between a response and a consequence, guiding future behavior.

Classical Conditioning

Pavlov's experiment demonstrated classical conditioning.
- A neutral stimulus (tone) was paired with an unconditioned stimulus (food), leading to salivation (unconditioned response).
- After conditioning, the neutral stimulus (now conditioned stimulus) elicited salivation (conditioned response).
Acquisition is the initial stage of learning.
Extinction is the gradual weakening and disappearance of a conditioned response.
Spontaneous recovery is the reappearance of an extinguished response after a period of no exposure to the conditioned stimulus.
Stimulus generalization is the tendency to respond to stimuli similar to the conditioned stimulus.
Stimulus discrimination is the ability to distinguish between a conditioned stimulus and similar stimuli.

Operant Conditioning

Operant conditioning involves learning through consequences of voluntary behaviors.
The Law of Effect states that behaviors leading to desirable effects are repeated, while those leading to undesirable effects are not.
Acquisition is the formation of a new response tendency.
Shaping involves rewarding behaviors that are closer to the desired behavior.
Reinforcement strengthens a response.
- Positive reinforcement adds something desirable.
- Negative reinforcement removes something undesirable.
Punishment weakens a response.
- Positive punishment presents an aversive stimulus.
- Negative punishment removes a rewarding stimulus.
Reinforcement schedules determine when a response is reinforced.
- Continuous reinforcement rewards every response.
- Intermittent reinforcement rewards only some responses.
- Ratio schedules reinforce based on the number of responses.
  - Fixed-ratio: Reinforcer after a fixed number of responses.
  - Variable-ratio: Reinforcer after a variable number of responses.
- Interval schedules reinforce based on the time elapsed since the last reinforcement.
  - Fixed-interval: Reinforcer after a fixed time interval.
  - Variable-interval: Reinforcer after a variable time interval.

Observational Learning

Observational learning involves learning by observing others.
Bandura's Bobo doll study demonstrated that children modeled the behavior they saw in adults.

Intelligence

Intelligence is the capacity to act purposively, think rationally, and deal effectively with the environment.
General mental abilities form the core of intelligence.
- The "g-factor" is a general intelligence factor.
- Gardner's theory outlines 8 different intelligences.
- Sternberg's triarchic theory proposes three intelligences: analytical, creative, and practical.
Alfred Binet developed the first intelligence test to measure children's mental age relative to their chronological age.
The Stanford-Binet IQ test was based on Binet's work.
The Wechsler Adult Intelligence Scale (WAIS) provides an overall IQ score and separate scores for verbal (language-based) and performance (nonverbal) intelligence.
Intelligence is highly heritable.
- Twin studies show that identical twins have more similar IQs than fraternal twins.
- Adoption studies show that siblings reared together have more similar IQs than siblings reared apart.
Environmental factors also play a role in intelligence.
- Environmental deprivation can negatively impact intelligence.
- Environmental enrichment can positively impact intelligence.
- The Flynn effect demonstrates that IQ scores have been steadily increasing across generations, likely due to factors like improved education and access to technology.
Reaction range theory proposes that genetics set limits on intelligence, and environment determines where individuals fall within those limits.
