Exam 2 (Assignments 6-10) Flashcards
learning
the relatively permanent changes in an organism’s behavior due to experience
classical conditioning
stimulus evokes a response originally invoked by a different stimulus
operant conditioning
responses controlled by their consequences
observational conditioning
behavior influenced by observing a model
Pavlov example: before conditioning
food: unconditioned stimulus / salivation: unconditioned response
Pavlov example: before conditioning + neutral stimulus
tuning fork: neutral stimulus / no salivation: no conditioned response
Pavlov example: during conditioning
tuning fork + food -> salivation (unconditioned response)
Pavlov example: after conditioning
tuning fork: conditioned stimulus, salivation: conditioned response
law of effect
things you do that result in something good are more likely to occur, while things you do that result in something bad are less likely to occur
positive reinforcement
+ +
positive punishment
+ -
negative reinforcement
- +
negative punishment
- -
three components of emotion
physiological, behavioral, cognitive
which area of the brain modulates emotion
the amygdala
positive in this context means
adding stimulus
negative in this context means
removing stimulus
reinforcement
strengthens response
punishment
weakens response
Schacter-Singer Two Factor Theory
“I label trembling as fear b/c I appraise the situation as dangerous” -> situational cues used to differentiate emotions - 1) autonomic arousal + 2) cognitive interpretation
Cannon-Bard Theory
emotion occurs when thalamus sends signals simultaneously to cortex and autonomic nervous system -> “The dog makes me tremble and feel afraid”
James-Lange Theory
conscious experience of emotion results from perception of autonomic arousal “I feel afraid because I tremble”
3 steps in memory
encoding, storage, retrieval
Shallow processing
structural encoding
intermediate processing
phonemic encoding
deep processing
semantic encoding
example of something that weakens encoding
interference
strengthens encoding
elaboration
sensory memory
preserves information in its sensory form for limited time (seconds)
short-term memory
limited capacity storage / 20 seconds. Rehearsing improves duration
working memory
actively holds transitory information. Longer than short-term, can be converted to long term
long term memory
unlimited information for lengthy periods, possibly permanent
4 components working memory
phonological loop, visuospacial sketchpad, central executive, episodic buffer
knowing how to drive stick
procedural memory
knowing the three types of long-term memory
semantic memory
childhood memory
episodic memory
knowing Columbus sailed in 1492
semantic memory
knowing how to play instrument
procedural memory
remembering what you did last weekend
episodic memory
in order to use memory
must be able to encode it, store it, and retrieve it
misinformation effect
recall of a witness event can be altered by introducing misleading post-event info
area of brain most responsible for memory
hippocampus
ways to improve memory
getting more sleep, stress management, using enrichment strategies
reasons for forgetting
ineffective encoding, decay, interference, retrieval failure, repression (motivated forgetting)
germinal stage
rapid cell division; placenta forms
