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
3 intelligences (Robert Sternberg)
- analytical intelligence
- creative intelligence
- practical intelligence
analytical intelligence
academic abilities or ability to solve well defined problems
creative intelligence
ability to react adaptively to new situations and to generate novel ideas
practical intelligence
ability to solve ill-defined problems
emotional intelligences
helps you to perceive, understand, manage, and use emotions in your interactions with each other
fluid intelligence
our ability to reason quickly and abstract
decrease as age increase
crystallized intelligence
accumulated knowledge and verbal skills
increase or remains the same as age increases.
Alfred Binet
- wasn’t trying to make an intelligence test
- trying to establish a child’s mental age in order to measure children intellectual development and predict how well they’d do in school
heretability
proportion of variability due to genes
fixed mindset
intelligence is biologically set and unchanging
growth mindset
intelligence is changing - more motivated
Theory of General Intelligence
Charles Spearman
Factor Analysis (g factor)
scores from testing are normally consistent across the board
controversial (diverse abilities)
Theory of Primary Mental Abilities
L.L. Thurston 7 factor theory (word fluency, verbal comprehension, spatial reasoning, perceptual speed, numerical ability, inductive reasoning, and memory) breakdown seems intuitive scores seem to vary together limited to what they see as intelligence
Theory of Multiple Intelligence
Howard Gardner 7-9 Independent Intelligences Your intelligence in one area doesn't depict your intelligence in another area. 1. Logical Mathematical Intelligence 2. Linguistic Intelligence 3. Spatial Intelligence 4. Musical Intelligence 5. Body-Kinesthetic Intelligence 6. Intrapersonal Intelligence 7. Interpersonal Intelligence 8. Natural Intelligence 9. Existential Intelligence
includes more than book smarts
intelligence vs. ability/talent
Triarchic Theory of Intelligence
Robert Sternberg
3 intependent intelligences
intelligence: things that will lead to real world success (reliable)
- Analytic Intelligence
- Creative intelligence
- Practical Intelligence
3 sides of the same coin
construct validity
describes the extent to which the theory is supported by the data or results of the research
content validity
extent that the test measures the construct accurately
test-retest reliability
high positive correlation between the first and second administration of a test
inter-rater reliability
multiple judges or rates view the same subjects and the observers ratings have a high correlation
Broca’s Area

language expression
damage to Broca’s area
trouble producing speech
halting/slowed
non-fluent aphasia, broca’s aphasia
(broken speech)

Theories of Language and Cognition
universalism
- thought comes before language (determines language/influences language)
Piaget’s Cognitive Development
Vygosky
language and thought are independent
children develop language through social interaction with adults who already know the language
Linguistic Determination
weak and strong determinism
how much influence they think language has on thought
weak determinism (language)
language influences thought makes it easier or more common to think in certain ways depending on how our language is structured
strong determinism (Whorfian hypothesis)
language determines thought completely (based off Hopii tribe)
Nativist/Innativist Theory of Language Development
children are born with the ability to learn language
Noam Chomsky - thought that humans have a language acquisition device or LAD in their brains that allowed them to learn language
critical period - birth - 9 years old
learning
acquire language through development
interactionist
biological and social factors have to interact in order for children to learn language
Vygostky
Limbic System
set of structures in the brain - many of those structures play an important role in regulation
4 important structures
hypothalamus
amygdala
thalamus
hippocampus
thalamus
two of these
sensory-relay system
directs senses to appropriate area in cortex
sense of smell is the only sense that bypasses the thalamus - own private relay system
amygdala
aggression center anger, violence, fear, anxiety destroying amygdala can cause a mellowing effect - dr.kluver - dr.bucy
kluver-bucy syndrome
bilateral destruction of the amygdala (impulsive)
hyperoralility
hypersexuality
disinhibited behavior
kluver-bucy treatment
benzos
hippocampus role in memory
creating new memories
turn short-term memories into long term memories
hippocampus damage
old memories remain - unable to create new memories
hypothalamus role
located below the thalamus
size of a kidney bean
regulate things in the body
regulating autonomic nervous system (epinephrine/adrenaline)
left hemisphere of the cerebral cortex
positive emotions - lead to more electrical activity on the L side of the brain than the right.
sociable kids, interested, and enthusiastic
right hemisphere of the cerebral cortex
negative emotions - more activity on the right side of the brain than the L
isolated kids, timid, fearful, avoidant, depressed
prefrontal cortex
area in the front of the brain, right behind forehead
higher order funxtions: language, information processing, logic
damage to prefrontal cortex
inappropriate, rude, ruff, bad behavior
sympathetic nervous system
fight or flight
afraid of something
increase respiratory rate for better oxygenation
adrenal glands release epinephrine/norepinephrine
decrease digestion (takes up too much energy)
pupils dilate
decrease salivation
increased heart rate
increased glucose release
parasympathetic nervous system
rest and digest pupils constricted increased salivation decreased heart rate decreased adrenaline release relaxed state decreased respiratory rate (moderate/decreased) decreased glucose release (increase glucose storage) increased digestion
emotion
subjective experiences that are accompanied by physiological, behavorial, and cognitive changes and reactions
cognitive reactions
mental assessments than can include apprasials of what is happening, expectations about the situation and general thoughts about the experience
physiological reactions
changes in your body
behavorial reactions
body language or facial expressions
universal emotions
- happiness
- sadness
- fear
- disgust
- anger
- surprise
james lange theory of emotion
two researchers
theory of emotions is due to the perception of your physiologic responses
event –> physiologic response –> interpretation of –> emotion
emotions follow directly from bodily responses - the person does not actively “intepret” their bodily responses in order to figure out their emotions
e.g. sad because you cry
cannon - bard theory
event –> physiological response + emotion
a person can experience physiological arousal without feeling any particular emotion
physiological response system was just too slow to produce emotions that often seemed to happen almost instantly
they believe that the physiological responses and the experience of emotion happen simultaneously
schacter - singer theory of emotion
physiological and cognitive responses may simultaneously form the experience of emotion
lazurus theory of emotion
experience of emotion depends on how the experience is cognitively apprasied
event –> apprasial (label) –> emotion + physiological response
damage to basal ganglia
problems with recognizing angry facial expressions
amygdala
most associated with recognition of facial expressions associated with fear
insula
associated with disgust. the anterior insula receives signals from olfaction and gustation
stressor
threatening/challenging event
stress
process by we appraise the enviromental threat
stress reaction
subsequent physical and emotional response
richard lazarus
determined that stress arises less from the actual events and more from our assessment of the event (our apprasial)
primary apprasial - inital evaluation that focuses on the threat in the present situation - irrelevant, benign/positive, stressful
if it is stressful, we move forward with the secondary apprasial
-involves the individual’s ability to cope with the situation (harm, threat [future damage?], challenge - how can the situation be overcome)
4 categories of stressors
- signficant life changes
- catastrophic life changes
- daily hassles
- ambient stressors
significant life changes
significant personal life change
holmes and rane stress scale (43 different major life stressors)
catastrophic events
unpredictable, large scale events
war, natural disasters (e.g. hurricane katrina)
daily hassles
e.g. tire blown minor events of our daily lives racism add up and take a huge toll most significant form
ambient stressors
global stressors e.g. pollution, smog, wildfires (LA) hard to control happening in background can negatively impact us without being consciously aware of their existence
Walter Cannon
homeostasis (maintenance)
homeostatic response to animals to threats or danger (stressors)
Fight or Flight Response to Stress
fight or run (SNS)
transition our body to get out of danger mode
increased heart rate
increased respiratory rate (more O2 in blood to tissues to expel more CO2)
increased peripheral vascoconstriction
push more blood to core/cruvial areas
turn off figestion, immune function, and ovulation
endocrine response to stress
chemical messages
adrenal glands
- medulla - catecholamine hormones (adrenaline and noradrenaline)
increased heart rate and increased blood pressure - supporting SNS
cortex –> glucocorticoid - cortisol
Tend and Befriend in Stress
(women > men)
huddle together to form support systems
oxytocin - pair bonding (integrated with estrogen)
Hans Seyle - General Adaptation Syndrome (GAS)
- Alarm Phase
- stress reaction kicks in
- heart racing and resource mobilizing
- fight or flight - Resistance Phase
- actual gihting or fleeing or huddling together
- stress hormones increase - Exhaustion
- stress resources depleted leads you here
- tissue and muscles become damaged
- dampened immunity can make us more susceptible to illness
- overexposure to stress
heart and vascular disease
increased blood pressure (blood vessel distension) leads to hypertension which can lead to vascular disease
vascular disease is an inflammation and plaque buildup
plaque is super attracted to fat and cholesterol, which sticks to these spots and nnarrows the blood vessels
worst place for vascular disease
coronary arteries
aka. arteries that feed our actual heart tissue
CORONARY ARTERY DISEASE
- heart tissue not nourished, it starts to die which is what we call a heart attack, entire body is in trouble
Metabolism in Stress
- extra nutrients are stored for later use
- cortisol and glucagon increase due to stress response
- extra glucose can exacerbate conditons such as diabetes
- extra blood sugar can lead to cardiovascular disease
reproductive abilities in stress
impeded by stress GIRLS - huge energy expense - shut down - no baby making chronic issues: pregnancy hormones can become chronically inhibited which can effect growth of eggs
BOYS
- decreased testosterone (doesn’t result in infertility)
- erectile dysfunction
- impotency
- less blood to penis
immune response to stress
ADAPTIVE white blood cells and antibodies INNATE basic - generic inflammation turned on too much
CHRONIC: immune systemm suppressed - more susceptible to illness (40% slower healing rate)
location of most glucocorticoid receptors
hippocampus (learning and memory)
frontal cortex (impulse control, judgement, planning, reasoning)
cortisol - atrophy of these areas due to over abundance of stress
Depression in stress
anhedonia - failure to feel pressure stop responding to serotonin : anterior cingulate "learned helplessness" perceived more stressors earn that you have no control decreased coping mechanisms
Anger in Stress
increased vulnerability to heart disease
type A: easily angered - prone to hostility and anger
type B : more easy going
Anxiety in Stress
amygdala (fears and phobias)
“flight”
Addiction in Stress
alcohol abuse (men > women) tobacco compound relationship between stress and addiction - impairment to frontal cortex - impaired judgement decreased coping mechanism
unavoidable stressors need to be managed. how?
- exercise
- meditation
- religion/faith
- cognitive flexibility
self-concept
how someont thinks about, perceives or even evaluates themselves
self aware = self concept
exisental self
most basic part of self concept
sense of being separate and distinct from others
self is constant
consistent
categorial self
CONCRETE - age, gender, size, skills
MORE DEVELOPED - traits, comparison, careers
Carl Rodgers
humanistic view of self concept
- self image - view we have of ourselves
- self esteem - self worth/value
- ideal self - what we wish to be
self - esteem
regard/respect that a person has one’s self
self-efficacy
belief in one’s capability to succeed in a certain situation
strong self-efficacy
- tasks to be mastered Recovery Interest Strong Enjoy
stronger sense of commitment
able to recover from disappointments
weak self-efficacy
Fail
Avoid
Lose
Lack
avoid challenging task
focus on personal feelings and negative outcomes
four major sources of self efficacy
- MASTERY OF EXPERIENCE
performing a task successfully will strengthen our sense of self-efficacy - SOCIAL MODELING
seeing people similar to ourselves
successfully completing tasks, raises our beliefs - SOCAL PERSUASIAN
getting verbal encouragement from others helps people overcome self doubt - PSYCHOLOGICAL RESPONSES
learning how to minimize stress and elevate mood when facing difficult or challenging tasks
low self-esteem + high self-efficacy
PERFECTIONISTS
- over critical and negative about themselves. quite capable in certain areas
locus of control
extent to which people perceive they have control over events in their lives
internal locus of control
person believes he or she can influence events and their outcomes
- attribute results to their own traits
control own destiny - tend to be happier
external locus of control
blames outside forces on everything. attribute events to environmental traits it causes
sigmund freud - psychosexual theory of development
describe how personality develops during childhoof - early childhood was most important age/period for personality development
- most personality is developed by the age of 5.
5 stages - completion = healthy personality
fixation : not solving problems in one stage, but moving to the next without fixing the problem
erikson -psychosocial theory of development
personality development occured over a lifespan
each stage of development was focused on overcoming a conflict
8 stages - outcome dependent on how people handle the stages
lev vykotsky sociocultural cognitive theory
children learn actively and through hands on experiences - active process
parents, caregivers, peers, cultural beliefs, attitudes, and language are all responsble for the deelopment of higher order learning 0 child internalizes the information they get from interaction with others .
stresses the importance of social interaction in development of cognition
theory incomplete because of theorist passing
lawerence kohlberg - moral development theory
right vs. wrong
believes in moral reasoning depends on the level of cognitive development
3 levels of moral development further divided into 2 stages
George Herbert Mead - The I and The Me
- Preparatory Stage
- interact throught imitation - Play Stage
- importance of social relationships
- pretend play - Game Stage
- start to understand attitudes, behavior, beliefs of “generalized other”/society
- multiple roles
- significant other
generalized other –> I (response to social self) –> me (social self)
generalized other –> me (social self)
our actual self is the balance between I and me
Cooley - Looking Glass Self
our view of ourselves from how we are perceived from others
- how do I appear to others
- what must others think of me
- revise how we think about ourselves
oral stage of psychosexual development
age : 0-1 years old

development : baby has to learn to ween off in order to advance to next stage
adult fixation : dependency/aggression (conflict) - smoking, biting nails, over-eating
anal stage of psychosexual development
