Psychology II Flashcards
inattentional blindness
we are not consciously aware of things that happen in our visual field when our attention is directed elsewhere within the field
change blindness
when we fail to notice changes in our environment
endogenous cues
more internalized and higer order - internal knowledge
e.g. cocktail effect
exogenous cues
external to any goals we may have, meaning we don’t have to tell ourselves to look for them in order for them to capture our attention
information processing model
brains are similar to computers. input is from the environment. we process it and output decisions
sensory memory (register)
first to interact with information in the environment
sight and sound are the most important
iconic memory and echoic memory
iconic memory
what you see (
echoic memory
what you hear (3-4 sec)
working memory (short-term memory)
whatever you are thinking about at this exact moment
7+/-2 pieces of information at a time
vary based on complexicity
reason why phone numbers are seven digits long
visiual, spatial, and verbal information
visuo-spatial sketchpad
visual and spatial information
phonological loop
verbal information (words and numbers)
central executive
tells visuo-spatial and phonological loop to work together which then goes down the episodic buffer which is connected to the long term memory
Explicit Memory (Declarative)
facts or events that you can clearly/explicitly describe
semantic : words (facts)
episodic : events
Implicit Memory (Non-Declarative)
things that aren’t easy to describe
procedural : steps/procedures
priming
previous experience influences your current interpertation of an event
encoding
moving information from working memory (short term memory) to more permanent storage (long term memory)
Rote rehersal
say the same thing over and over again
least effective
dosen’t require you to process the information
chunking
group information into meaningful units
mnemonic devices
imagery
pegword
method of loci
acronym
imagery (mnemonic device)
vivid mental picture of what you are trying to remember
pegword and method of loci
anchors and linking new information to anchors along a specific path. pegword - verbal anchors. method of loci - location anchors
acronym
one letter of a familiar work stands for the first letter of new information
Self Referencing
relating the information to you
ex : preparing to teach
Spacing
structure of studying space out study session long-term information let's you know what you don't know self-testing
procedural memory location
basal ganglia
semantic memory location
neocortex
episodic memory location
hippocampus
explicit memory location
medial temporal lobe
retreival
call up a memory or think of something you learned
free recall
without any cues or any particular order
remember 1st items on the list (primacy)
remember last items on the list (recency)
fuzzy on the items in the middle.
cued recall
still have to produce an answer, but you get more retrieval cues to help you
recognition
more cues than cued recall
source monitoring
knowing where various pieces of information are coming from.
ebbinghaus
first person to really look at decay in memory
the more integrated the inital memory is, the more stretched out the rate of forgetting is. but it all follows the same pattern, no matter the material
relearing
faster rate if some of the information is stored in your long term memory
retroactive interference
interference that goes backward. some new piece of learning seems to reach back and impair your ability to retrieve something you used to know
proactive interference
interference moving foward - gets in the way of your ability to learn and retrieve something correctly in the future
Declining Abilities when Aging
Recall
Episodic Memories
Processing Speed
Divided Attention
Stable Abilities when Aging
Implicit Memory
Recognition
cognitive changes are NOT all bad
Improving Abilities when Aging
Semantic Memory (until 60 years) Crystallized IQ (using knowledge and experience) Emotional Reasoning
Dementia
decline in memory and other cognitive functions - excess damage of brain tissue (multiple strokes/other causes)
most common form of dementia
Alzehimer’s
unknown cause
neurons die over time
cerebral cortex shrinks in size
symptoms of Alzehimer’s
memory loss - inability to encode/retrieve new memories
attention, planning, semantic memory, abstract thinking, language
Emotional Instability
Loss of Control over bodily functions
Terminal
increased Amyloid Plaques in the brain
Korsakoff
Aphasia, Anterograde and Retrograde Amnesia
decrease of B1 or thiamine
linked to Malnutrition, Alcholism, and Eating Disorders
May have damage to parts of the brain resulting in poor balance, abnormal eye movements, mild confusion
pre-cursor to Korsakoff
Wernicke’s Encephalopathy
how to reverse the damage or at least prevent it
if wernicke’s encephalopathy is diagnosed in time, it is possible to reverse the damage. if untreated, will progress into Korsakoff’s.
symptoms of Korsakoff
severe memory loss
confabulation (makes up things)
not progressive, if treated. people can get better
dependent on how early it is diagnosed and how well the patient follows treatment guidelines
ways to get better with korsakoff
thiamine injections
healthy diet
abstain from alcohol
Hierachal organization
thought concepts were organized from higher order categories down to lower order categories and their exemplars
modified semantic network
every individual semantic network develops based on their experience/knowledge
spreading activation
activating one concept and pulling related concepts along with it.
Piaget’s Stages of Cognitive Development
Sensorimotor Stage (0-2 y.o.)
Preoporational Stage (2 - 7 y.o)
Concrete Operational Stage (7-11 y.o.)
Formal Operational Stage (12 - up)
Sensorimotor Stage
0-2 y.o.
sensori - children gather information about their world with their ages, so through sight, smell, taste, hearing and touch.
motor - they are very active
OBJECT PERMANENCE - infants don’t recognize that objects still exist even though they can’t see them
Preoperational Stage
2-7 y.o.
operational - mental operation (imagining things or mentally reversing actions)
- children develop/engage in pretend play
- using symbols to represent things
EGOCENTRIC - dont understand that other people have a different view than then
Concrete Operational Stage
7-11 y.o.
learn the idea of CONSERVATION (tall skinny glass vs. short fat glass)
reason about mathematics
Formal Operational Stage
12 and up
reason about abstract concepts and think about consequences of potential actions.
reason out what might occur
sophisticated moral reasoning
schemas
frameworks by which we organize and interpret new information
grow and develop through assimilation and accomodation
assimilation
interpret new experiences in terms of our current schemas
accomodation
adjusting schemas to incoporate new experiences
well-defined problems
clear starting and ending point
ill-defined problems
ambigious ending and starting point
trial and error
just take random guesses until something finally works
algorithim
logical, step-by-step procedure or trying solutions until you hit the right one
heuristic
mental shortcut to find the solution faster
- don’t guarantee a solution
- very common
means-end analysis
analyze the bigger problem and make it into smaller problems. current state –> goal
working backwards
start with goal state and make suggestions to get to current state (mathematical proofs)
decision making
make a judgement about the desirability of some outcome
-most people use a heuristic/mental shortcut
decision making heuristic
availability - examples that come to mind
representativeness - matching prototypes (conjunction fallacy)
overconfidence bias
our tendency to be more confident than correct
-could be due to fluency or ease of processing
belief perseverance bias
ignore/rationalize disconfirming facts
confirmation bias
seek out only confirming facts
framing
how you present the decision
intelligence quotient
mental quality allowing you to learn from experience, solve problems, and use your knowledge to adapt to new situations
general intelligence
people who score well on one type of test tend to score well on other tests (qualitative vs quantitative)
g factor
general intelligence
