Semester 2 Flashcards
Ivan Pavlov
Dogs drooling when bell rings
Unconditioned Stimulus (UCS, US, UC)
Unconditionally - automatically and naturally - triggers a response
Unconditioned Response (UCR, UR)
Unlearned, naturally occuring response to the unconditioned stimulus
Conditioned Stimulus (CS)
After association with an unconditioned stimulus, comes to trigger a conditioned response
Conditioned Response (CR)
Learned response to a previously neutral conditioned stimulus
Generalization
Tendency to respond to stimuli similar to the CS
Discrimination
Learned ability to distinguish between a conditioned stimulus and other stimuli
Operant Conditioning
Behavior is strengthened if followed by reinforcement or diminished if followed by punishment
Skinner Box
Bar or key that an animal manipulates to obtain a reinforcer like food or water
Shaping
Reinforces guide behavior towards the desired target behavior through successive approximations
Positive Reinforcement
Any event that strengthens the behavior
Negative Reinforcement
Removal of a punishment or an aversive stimulus; it STRENGTHENS behavior
Observational Learning (Albert Bandura)
Learning by observing and imitating behaviors
Modeling
Observing and imitating a specific behavior
Bobo Doll Study (Albert Bandura)
Hypothesized that children would imitate aggresive behavior they observed
Modeling Violence
Research shows that viewing media violence leads to an increased expression of aggression
Flashbulb Memory
Highly emotional moment; clear, strong, and persistent memory
Working Memory (Short-Term Memory)
Conscious processing of information; 7 ± 2 items; 20-30 seconds
Long Term Memory
Relatively permanent and limitless
Mnemonics
Memory aids
Method of Loci
Items are mentally associated with specific physical locations
Chunking
Organizing items into familiar, managable units; acronyms are a type of chunking
Retrieval Cues
Anchors (words, places, emotions, etc.) that help retrieve memory
State-Congruent Memory
Recall experiences that are consistent with one’s current mood
Encoding Failure
Original information was not encoding correctly
Proactive Interference
Disruptive effect of prior learning on recall of new information
Retroactive Interference
Disruotive effect of new learning on recall of old information
Source Amnesia
Attirbuting something in our memory to the wrong source
Instincts
Biological, genetic programming; Instinct - complex behaviors with fixed patterns
Drive Reduction Theory
A physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need (the reduction)
Homeostasis
Maintenance of a steady internal state
Hierarchy of Needs (Abraham Maslow)
Lower motives must be met before higher needs; Physiological, Safety, Belongingness and Love, Self-Esteem, Self-Actualization (Full Potential)
Hypothalamus
Plays a role in the regulation and control of hunger
Anorexia Nervosa
Normal-weight person still feels overweight
Bulimia Nervosa
Overeating followed by vomiting using laxatives, etc.
Catharsis
“Releasing” aggresive energy (through action or fantasy) relieves aggressive urges
