Final Flashcards
leLearning
A relatively permanent change in behavior that results from experience, can’t be due to maturation, temporary states (fatigue, drugs), or natural response
Classical Conditioning
Type of learning in which a neutral stimulus acquires the ability to produce a response that was originally produced by a different stimulus
Stimulus
Any event or object in the environment to which an organism responds
Pavlov’s Experiments
Unconditioned stimulus, unconditioned response, conditioned stimulus, conditioned response
Unconditioned Stimulus
A stimulus that automatically leads to an observable response prior to any training
Unconditioned Response
The observable response that is produced automatically to an unconditioned stimulus
Conditioned Stimulus
The neutral stimulus that is paired with the unconditioned stimulus
Conditioned Response
The acquired response that is produced by the conditioned stimulus in anticipation of the unconditioned stimulus
Conditioned
Learned
Unconditioned
Unlearned, automatic
Little Albert
Fears are learned, not born with them (rat with loud noise, conditioned response)
Acquisition
Initial stage, before neutral stimulus becomes conditioned stimulus
Extinction
Conditioned stimulus is not paired with the unconditioned stimulus, so conditioned stimulus diminishes (bell not paired with food, after a while salivation will not occur)
Spontaneous Recovery
Reappearance of extinguished conditioned stimulus
Generalization
Stimulus similar to conditioned stimulus elicit similar response
Discrimination
Distinguish between similar stimuli
Operant Conditioning
Type of learning in which the consequences of behavior are manipulated in order to increase or decrease the frequency of an existing response
Classical Conditioning
Organism learns associations between events it doesn’t control
Operant Conditioning
Learning associations between own behavior and resulting events
Skinner
Behavior that is followed by rewarding consequences are repeated
Shaping
Gradually molding a desired behavior by reinforcing any movement in desired direction (pigeon eats when light is on, moves in a circle, reinforces)
Positive Reinforcement
Reward following desired behavior
Negative Reinforcement
Remove unpleasant stimulus following behavior
Positive and Negative Reinforcement
Both increase preceding response, primary reinforcers/reinforcers secondary
Punishment
Consequences that decrease the likelihood of responding in a similar way again
Positive Punishment
Do something to decrease behavior, prevent sucking thumb - hot sauce
Negative Punishment
Take away something to decrease behavior
Reinforcement Schedules
Fixed ratio, variable ratio, fixed interval, variable interval
Fixed Ratio
Reinforcement occurs after a fixed number of responses, pause after reinforcement, assembly line workers = pay/pairs made
Variable Ratio
Reinforcement after an unpredictable number of responses, slot machine, highest response rate
Fixed Interval
Reinforcement after fixed period of time, lowest response rate, long pause after reinforcement
Variable Interval
Reinforcement after an unpredictable time interval, check social media for comments, stable/high response rate
Observational Learning
Learn by watching others - social learning, Bandura Bobo doll experiment - amount of aggression
Remembering Requires
Encoding, storage, retrieval
Encoding
Translating information into neural codes
Storage
The process of retaining information
Retrieval
Getting information out
Atkinson - Shiffrin Model of Memory
3 memory systems - sensory, short-term, long-term
Sensory Memory
Purpose - memory from senses, duration - up to 2 seconds, capacity - large
Short-Term Memory
Purpose - temporarily stores sensory information, duration - up to 30 seconds, capacity - 5-9 items, most items lost without rehearsal
Long-Term Memory
Purpose - relatively permanent storage, duration - relatively permanent, capacity - relatively unlimited
Types of Short-Term Memory
Displacement, chunking
Displacement
When STM fills ip, incoming information pushed out existing information (which is forgotten)
Chunking
Grouping bits of information into larger units, overcome limits of 7 bits of information
Types of Long-Term Memory
Declarative/explicit, non-declarative/implicit
Declarative/Explicit
Episodic - mental diary (“I had a great bike ride last weekend”), semantic - general knowledge, facts (“Bikes have wheels”)
Non-Declarative/Implicit
Motor skills, classically conditioned responses, habits
Tip-of-the-Tongue Phenomenon
Retrieval failure; sensation of knowing that you know it
Recall
Retrieve memory with few cues, fill in the blank
Recognition
Identify material as familiar, multiple choice
Visualization
Using mental imagery can help you remember that information
Elaborative Rehearsal
Linking new information to previously stored information, deep processing
Context
Much easier to retrieve certain memories when the “context” or circumstances around the memory are the same for both the original encoding and retrieval (childhood home)
Mnemonic Devices
Memory improving technique based on encoding items in a special way, making up songs or phrases
Distortion
Alternation of memory to fit existing beliefs and expectations, usually positive, remember A’s better than D’s
Misinformation Effect
Incorporate misleading information into memory, Loftus (S’s shown video of car driving, later 1/2 were asked how far the car was going when it passed the barn, other 1/2 were asked how fast the car was going, 6x more people in the first group mistakenly remembered a barn in the video)
How Often Are Eyewitnesses Mistaken?
Participants saw staged crime, 1 hour later they saw mug shots and were asked to ID the suspect, 1 week later asked to ID the suspect from a lineup, suspect was not in mug shot or the lineup (20% ID innocent person in mug shot, 8% ID innocent person in mug shot or in lineup, seeing mug shot leads to familiarity)
Eyewitnesses
Eyewitnesses are notoriously awful at remembering events
Loftus’ Research on Memory Construction
Did you see the broken headlight? - More false reports of broken headlight, working - smash vs. hit
Change Blindness
Things that change go unnoticed because we are not paying attention
Flashbulb Memory
A distinct, detailed memory of an emotional or important event, research following 9/11 showed that even flashbulb memories can be inaccurate (73% of people recalled seeing the first plane hit, but no footage was shown at the time)
Imagination
May also be a factor in false memories, imagination inflation, participants asked to imagine something that never happened to them were more likely to falsely state that the event happened to them
Things That Affect Eyewitness Errors
First describe perp then look at photos - less errors, lineup - composition, sequential lineup, race, weapon, influence accuracy, avoid leading questions, confidence does not equal accuracy, James Tillman
Personality
Unique pattern of traits and behavior possessed by each individual, relatively stable and enduring patterns of thoughts/feelings/and actions
Traits
Essential characteristics that distinguish different people, often described using adjectives (cheerful), limited in number, each individual differs in degree of a trait
Big 5
Cross-cultural number, describes and organizes personality with the fewest number of traits
Problems With the Big 5
Lack of explanation - why do people develop these traits?, lack of specificity - personality stable after 30 and least stable before 3 and characteristics that last entire life not identified, ignores importance of situation - personality is stable but situation plays role
Big 5 Factors
Openness, conscientiousness, extraversion, agreeableness, neuroticism
Openness
Low scores - down-to-earth, uncreative, conventional, uncurious, high scores - imaginative, creative, original, curious
Conscientiousness
Low scores - negligent, lazy, disorganized, late, high scores - conscientious, hard-working, well-organized, punctual
Extraversion
Low scores - loner, quiet, passive, reserved, high scores - joiner, talkative, active, affectionate
Agreeableness
Low scores - suspicious, critical, ruthless, irritable, high scores - trusting, lenient, soft-hearted, good-natured
Neuroticism
Low scores - calm, even-tempered, comfortable, unemotional, high scores - worried, temperamental, self-conscious, emotional
Sigmund Freud (1856-1939)
Psychoanalysis - theory of personality and therapy for treating psychological disorders
Levels of Consciousness
Conscious - aware, tip of the iceberg, pre-conscious - can be brought to surface, not aware, unconscious - most things are here, anxiety provoking, never been aware, root cause of psych disorders
