P/S Flashcards
Binocular cues
Retinal disparity
Convergence ( far away - eyes relaxed; close - eyes contract)
Monocular cues
relative size relative height interposition shading and contour motion parallax ( far away- slower; close - faster)
Visual Constancy
our perception of object doens’t change even if it looks different on retina
size constancy
shape constancy
color constancy
Inner ear muscle adjustment
loud noise - contract
Sight Adaptation
light adaptation - pupils constrict, rods and cones become desensitize
dark adaptation - pupils dilate, rods and cones start synthesizing light sensitive molecules
Just noticeable difference
threshold at which you’re able to notice a change in any sensation ; smallest difference that can be detected 50% of the time
Absolute threshold of sensation
the minimum intensity of stimulus needed to detect a particular stimulus 50% of the time
Absolute threshold influncers
Psychological states: expectations experience motivation alterntess
Subliminal stimuli
stimuli below the absolute threshold
Semicircular canals- filled with
filled with endolymph

Signal Detection Theory Purpose
looks at how we make decisions under conditions of uncertainty ; “discerning between important stimuli and unimportant “noise”
Origins: sonar
Signal Detection Theory; d’
d’ is the strength of a signal
- hits > misses for strong signal
- misses > hits for weak signals
Signal Detection Theory; c
c is the strategy used
- 2 strategies: Conservative and Liberal
- Conservative - always say no unless 100% sure signal’s present - get misses
- Liberal - always say yes unless 100% sure signal’s absent - get false alarms
Signal Detection Theory; Signal Distribution Graph
2 lines are the noise and the signal
-d’ - the difference between the two
Ideal Signal Detection Strategy
c = 0
- minimizes misses and false alarms
Conservative signal detection strategy
c>1
Liberal signal detection strategy
c <1

Method of Constant Stimulation
better than method of limits cause always presenting so no error of habituation and expectation; can do absolute thresholds where present stimulus randomly or ask difference thresholds (for which there has to be a constant stimulus with each of the varied levels)
Method of Adjustment/Method of average error
ask subject to control level of stimulus, instructs them to alter it until it is just barely detectable against the background noise or same level of another stimulus

- can explain how IV and DV are related
- IV accounts for variations in DV
- IV variations account for variations in mediator
- mediator variation account for variations in DV
- **when a mediator is added to the mode, the relationship between IV and DV decreases
Moderating Variable
variable that specifies conditions under which a given predictor is related to an outcome; explains “when” a DV an IV are related; influences the strength of a relationship between two other variables

Symbolic Interactionism
significance we given to objects, events, symbols…we interact with the world and each other to give meaning to things; focus on individual and how they behave; people are created by their society and act based on past experiences and meanings they’ve given things
- not everyone gives same meaning to same things
- subjective meaning people believe to be true; meaning is the central aspect of human behavior, we act towards things based on ascribed meaning an use language to generate meaning through interactions
Functionalism
- *all about institutions**Look at stability of a society, society as a whole and how institutions that make up the society adapt to keep society stable and functioning
- society is heading towards equilibrium between institutions and social facts ( how local business must adapt to new ways to cater to customers)
- -institutions remain constant and only make minor change when stability is lost in order to return to equilibrium
- social culture that shapes society as a whole
Macrosociology
large scale perspective, big phenomena, social structures, institutions, whole civilizations/populations
- look for patterns and effects on big picture
- Functionalism
- Conflict Theory
Conflict Theory
society is made of institutions that benefit powerful and create inequalities; large groups are at odds until conflict is resolved and new social order is created
- focus on different groups in society, based on ideas of Karl Marx that believed society evolve through several stages ( feudalism –> capitalism –> socialism)
- bourgeoisie vs proletariat
- class consciousness- lower class united to create this by notice their similarities
- thesis - what is; antithesis: desire to change thesis –> Thesis and antithesis cannot exist peacefully so gotta change –> Synthesis: of the two by creating a new state and thus new order

Illness Experience
process of being ill an how people cope with illness; being ill can change a person’s self-identity
Social Epidemiology
look at health disparities through social indicators like race, gender, an income distribution, and how social factors affect a person’s health; looks at contribution of social and cultural factors to disease patterns in populations ( social determinants of disease)
Functionalism- Social Facts
ways of thinking and acting formed by society that existed before any one individual and will exist after any individual is dead; only noticed when we resist ( ex law)
Functionalism- institutions
structures that meed the needs of society like education systems, financial institutions, marriage
Functionalism’s Cell
society is dependent on structures that create it - like cell is dependent on parts that make it up
- manifest functions - business to meet a certain service
- latent functions- unintended functions, indirect effects of institutions
- Social Dysfunction- process that has undesirable consequences and may reduce the stability of society
- Small vs large societies - small societies are held together by similarities; large societies become interdependent on each other as everyone is specialized in different roles; social change threatens interdependence!!! SO institutions adapt only enough to accommodate change to maintain mutual interdep
Ludwig G’s expansion on Conflict Theory
said that society is shaped by war/conquest and cultural/ethnic conflicts lea to certain groups becoming dominant
Max Weber’s Input on Conflict Theory
Didn't see class the major/supreme stratification factor several factors moderate people's reaction to inequality -did not believe collapse of capitalism was inevitable
Social Constructionism
people actively shape their reality through social interactions so nothing’s inherent – things are social products made of the values of society that created it
- Berger + Luckman - ideas are created through historical processes that are socially defined and culturally distinct
- knowledge and world aspects are not real, only exist because we give them reality through social agreement
- *we attach different meanings to different behaviors an have preconceptions of different people ( stereotypes)
Social Construct
concept/practice everyone in society agrees to treat a certain way regardless of its inherent value, ex. money
-the self is a social construct too - our identity is created by interactions with other people, and our reactions to the other people
Weak Social Constructionism
proposes that social constructs are dependent on brute facts which are the most basic and fundamental facts like quarks in atoms, don’t rely on other facts
-institutional facts are created by social conventions and do rely on other facts, ex. money depends on the paper we have given value
Strong Social Constructionism
the whole of reality is dependent on language and social habits
-all knowledge is a social construct, no brute facts; we created the idea of quarks an everything else; no facts that just exist
George Mead
believed development of individual was a social process as were the meanings individuals assigned to things; people change based on interactions with objects, events, ideas, others, and assign meaning to things to decide how to act
Herbert Blumer’s continuation of Mead
1- we act based on meaning
2-different people assign different meaning to things
3-the meaning we give something isn’t permanent, it adapt

- assume people are rational ( weigh costs and benefits) and act in self-interest ( personal desires and goals)
- 3 assumptions ( completeness, transitivity, and independence of irrelevant alternatives)
Exchange Theory
application of rational choice theory to social interactions
- look at society as a series of interactions between individuals - self-interest and interdependence
- address decision making via cost/benefit analysis ( seek reward, avoid punishment)
- ex. sexual selection, social selection
- also the more often a reward is available, the less valuable it is ( supply/demand)
Social Selection
- differential actions of social conditions or agencies on longevity and reproductive rates of individuals an strains in population
- idea that an individual’s health can influence their social mobility and social conditions can affect reproductive rates of individuals in a population

Age Stratification Theory
suggests age is way of regulating behavior of a generation
Activity Theory
look at how older generation looks at themselves – certain activities or jobs lost and those need to be replace so elderly can be engaged ( maintain moral well being)
Disengagement Theory

Growth Rate factors
fertility, migration, mortality
- increase: births and immigration
- decrease: death and emigration
- growth is not always a positive number, growth rates of some countries is negative
Stages of Demographic Transition
1-early expansion-high birth rates due to limited OCP and high death rate due to disease/poor nutrition; large young and small old population; overall population remains fairly stable ( skinny pyramid)
2-Late expanding-beginning of development and improvement in conditions, population rises as death rate decreases-low death rate ; rapid increase in pop( regular pyramid)
3-stationary-death and birth rates fall cause OCP and better conditions, not economically beneficial, slower expansion and longer live elderly; slow increase in pop (half oval)
4-constricting-population stabilizes, both birth rates an death rates are low; stable population ( priest circle hat)
5-speculation, Malthusian Theorem suggests negative growth rate where run out food and apocalypse ( funny priest triangle hat)

Intersectionality
consider all the different levels of discrimination
Means of Production
way we produce goods, factories and farms there's a class divide; the wealthy own things and higher large amount of workers who don't own any of the means of production
Class Consciousness
Karl Marx and Conflict Theory again- workers in working class don’t realize they’re being exploited and oppressed by this capitalistic model of working and when they develop class consciousness they have solidarity and struggle to overcome oppresssion
False Consciousness
instead of solidarity of class consciousness solidarity, they are unable to see their oppression and commonalities

Carl Rogers and Humanistic; 3 pieces of self-concept
self image = what we believe we are
self esteem= how much value we place on ourselves
ideal-self= what we aspire to be
**when ideal self and real self are similar, we have a positive self concept; if not, we have incongruity

Mead’s I
unsocialized, non-conforming, spontaneous
-response to the Me/attitudes of others
Mead’s Self

Cooley’s Looking Glass Self
socialization shapes our self-image;
-“looking glass self” - person’s sense of self develops from interpersonal interactions with others
3 steps
-how do I appear to others
-what do others think of me

extreme disapproval of a person based on some behavior or quality of that person; typically a culture will collectively stigmatize a person based on overt physical/deviant characteristics
Self-Stigma
individual can internalize all the negative stereotypes, prejudices, and discriminatory experiences they have had and feel rejected by society and then isolate selves
First Impressions

Evolutionary Game Theory
those with best fit to environment will survive and pass on to offspring, and those genes will become more common in successive generations; reproduction and environment are central
- predicts the availability of resources and social behavior; strategy of each individual depends on strategy exhibited by other players
- *diff from game theory cause game theory involves INTENTION while evolutionary game theory may not conscious intention on part of players

behavior is motivated by threat of something unpleasant; taste aversion - no longer eat something due to unpleasant experience
Adaptive Associations
those who have a biological advantage are learned faster than learning with no biological value
Escape Learning
escape an unpleasant stimulus, like fire - there’s an element of surprise cause you’re thrown into the condition and need way out to terminate an ongoing stimulus; response is conditioned to escape in response to stimuli and then stimuli goes away
Avoidance
avoid fire before it arrives–there’s a signal before aversive situation; results in continue avoidance cause reinforced by removal of pain/undesireable stimuli
Persuasion components and Elaboration Likelihood Model
method for attitude/behavior change; elaboration likelihood model explains how people influenced by content of speech vs more superficial features
- Message characteristics- message itself, clarity, how well thought out
- Source Characteristics- their level of expertise, trustworthy, credibility, physical environment
- Target characteristics- characteristics of listener, such as mood, self-esteem, alertness, intelligence
2 Paths of Information Processing
Central- people are persuaded by the content of argument - can lead to deep processing and results in a lasting attitude change
Peripheral- don’t care, little motivation/interest- leads to shallow processing of information and creates a temporary attitude change
Reciprocal Determinism
interaction between a persons’s behaviors, personal factors ( motivation), and environment
- Social-cognitive theory

views behaviors as being influenced by people’s actions and cognitions in their social context; talking about interactions between individual and situation they’re in
Learned Helplessness
when tone is sounded dogs receive electric shock, but could press button to stop the shock but don’t because were in previous situation where had no control– therefore uncontrollable bad events can lead to perceived lack of control, which leads to general helpless behavior
Tyranny of Choice
too many choices can negatively impact our cognition and behavior - one result is information overload is a result which can lead to decision paralysis and increased regret over choice made
Desires and Temptation
humans have desires which aren’t necessarily bad but they can become a temptation ( when they conflict with our long-term values and goals) – self-control is focusing on long term goals while putting off short-term temptations ; marshmallow test and kids
Ego Depletion

*focus on observable and measurable behavior
Skinner-strict behaviorist
Pavlov- classical conditioning
Personality Traits/Trait Thoery
*stable characteristic –> consistent behavior
stable predisposition towards a certain behavior; straightforward way to describe personality; puts it in patterns of behavior

factors underlying human personality ( fewer and more abstract)
Gordon Allport
4500 different descriptive; 3 categories
Cardinal Traits- characteristics that direct most of person’s activities- dominant traits, influence all our behaviors, including secondary and central traits

Infromation Processing Model
proposes our brains are similar to computers- we get input from environment, process it, and output decisions
- assumes a serial processing except computers do serial processing while our brain does parallel processing
- bottom-up
- limited storage capacity and limited attention capacity
Sensory Memory/Sensory Register
temporary register of all senses you’re taking in
iconic - half sec
echoic - 3-4 secs
Sensory Memory Tests
partial report technique or whole report technique
Working memory (7 +/- 2)
what you’re thinking at the moment; magic number 7 - you can hold 7 +/- 2 pieces of information at a time
-WM explains serial position effect
Processing Order
central executive coordinates visuo-spatial and phonological loop information –> stored episodic buffer –> long term memory (unlimited)
Visuo-spatial sketchpad
visual and spatial information processed here
Phonological loop
verbal information processes here, capacity of about 2 seconds
Dual Coding Hypothesis
it’s easier to remember words associated with images than either one alone
Method of loci
imagine moving through a familiar place in each place leaving a visual representation of topic to be remembered
Long-term Memory
capacity is unlimited; 2 main categories - explicit ( declarative), and implicit ( non-declarative)
Explicit/Declarative
explicit are facts/events you can clearly describe
Semantic Memory- form of explicit memory
facts; or has to do with words- anytime you take vocabulary test or state capitals, remembering simple facts
Episodic Memory-form of explicit memory
event-related memories
Implicit/Non-declarative/Procedural memory
implicit memories are things you may not articulate, such as riding a bicycle
- all memories formed by conditioning are implicit, unconscious, habits
- habits/implicit memory is stored int eh ganglia
Priming-form of implicit memory
previous experiences influence current interpretation of an event; less additional activation is needed
*prior activation of nodes/associations often without our awareness
Negative Priming
previous exposure to a stimulus/event unfavorably influences new one
Encoding
transferring sensory information into memory ( from temporary store in working memory to permanent store in long-term memory
Retrieval Cues
Priming
context ( environment you encode and take test in)
State-dependent ( your state at moment)
Cued Recall
give “pl” for planet
False information
inaccurate recollections of an event
Schema
mental blueprint containing common aspects of world, often used instead fo reality
Misleading information
car crash video, language used can influence memory and cognition
Source monitoring/source amnesia
when people recall information they often forget the information’s source
knowledge but can’t recollect from where, when, how
Flashbulb memories
highly vivid memories, often emotional, BUT still susceptible to reconstruction cause a memory is just neural connections; connections between neurons strengthen or weaken ( long term potentiation )
Lont term potentiation
with repeated stimulation, the same pre-synaptic neuron converts into greater post-synaptic neuron, stronger synapse, and when it lasts longer called long term potentiation – learning!!
Decay
when we don’t encode something well, or don’t retrieve it for a while, we can’t at all anymore
Ebbinghaus - initial rate of decay is fast but then levels out after about 30 days
Relearning
just because you can’t retrieve something doesn’t mean it’s completely gone– take less time to learn things second time around cause of savings
Interference
Retroactive- new learning impairs old information
Proactive-something you learned in past impairs learning in future

2-7 egocentric ( no empathy or inability to understand perspective of others) pretend play imagine no conservation
Concentrate Operational
7-11 conservation learned begin to learn empathy math skills, reasoning, logic conversion BUT NO HYPOTHETICAL reasoning
Formal Operational Stage
12+
reason abstract/hypotheticalconsequences and reason consequences, where sophisticated moral reasoning begins to take place
Schemas, Assimilation, Accomodation
we can accommodate by adjusting previously existing schema or adding new ones

Hierarchical Semantic Network Model
initially thought higher order to lower order categories; animal –> bird –> ostrich
Modified Semantic Network Model
not hierarchical but based on the associations and evidence that an individual develops based on experience and knowledge
when you activate one concept, pulling related concepts with it based on strength of connection
stronger nodal links means decrease processing time

Behaviorists on Language and Cognition
believe language is just conditioned behavior- we learned it
Nativists on Language and Cognition
rationalist, language must be innate
Theory of universal Grammar
all languages are alike in structural foundation and cause common rules and patterns; we are able to speak without fomral instruction
Universalism on Language
thought determines language completely - thought dictates language and language is created from a set of universal semantic distinctions and constructions which shape human language
Piaget on Language
he believed once children were able to think in a certain way, they then developed language to describe those thoughts so cognition influences language development
Vygotsky on Language
language and cognition are both independent but converge through development; eventually learn to use them at the same time
Weak Linguistic Determinism aka Linguistic Relativisim
language influences thought/cognition “girl pushes boy”
Strong Linguistic Determinism aka Sapir-Whorfian Hypothesis
language determines cognition/thought ( Hopi have no grammatical tense)
*people understand their world through language, and language in turn shapes how we experience hte world
Language Parts
Lexicon- set of vocabulary items
Lexical access- identify a word and connect to its meaning which has been store din long term
Phonology- phonetic component “ sound” - 40 in english
morphology- structure of words, grammatical system
Semantics- meaning associated with word
Syntax- how words put together in sentences
Pragmatics- dependence of language on context and pre-existing knowledge, cadence, inflection
Neural Networking theory
innate language mechanism, that can be activated by experience
Nativist (innatist)
Noam Chomsky
children are born with ability to learn language; each society has its own language; language is innate
Chomsky’s language acquisition device (LAD later called universal grammar - all languages shared some basic elements like nouns, verb) that allowed them to learn language
-along with idea there’s a critical period from birth to 9 years old, the period of time a child is most able to learn a language
*LAD only operates during critical period; once start using LAD it specialized to your language and unable to detect sound and grammar from other lanague
Baby word production
9-12 months: babble 12-18 months: 1 word/month 18-20 months: explosion of language and combos 2-3: longer sentences, 3 words + 5 yrs: rules of lanageu are mastered
Learning Theory of language/ Behaviorist
BF Skinner
children aren’t born with anything, only acquire language through reinforcement; learn to say mama cause every time say that, mother reinforces behavior ( doesn’t explain words produced that have not been heard before)
Skinner- behaviorist that models are trained in lanaguge by operant conditioning
Social Interactionist Approach of language
Vygotsky
believe biological and social factors have to interact for children to learn language
children’s desire to communicate with adults makes them learn language
Global Aphasia
when both Wernicke’s and Broca’s areas are damaged -
Arcuate fasiculus
2 areas connected by bundle of nerves- when damaged, conduction aphasia - ability to conduct between listening and speaking is disrupted
Stroke to left hemisphere
can’t speak, over time with therapy some can retain other speech-related parts of brain by creating new connections - neural plasticity
Corpus callosum
if severed have a split-brain patient – surgery effects language since right side of brain can’t communicate with the left language side; have to put things in right visual field in order to process them since would synapse in left hemisphere ( cause contralateral)
Limbic system
HAT Hippo
Kluver-Bucy syndrome
destroy amygdala bilateral–> mellow, hyperorality, hypersexuality, and disinhibited behavior, impulsive, ignore social behaviors

6 Universal Emotions
Stacey F. DASH - sadness, fear, disgust, anger, surprise, happiness
Schacter Singer/ 2 factor theory
E –> physio and cog –> emotion –> action
Lazarus theory
emotion depends on how the situation is appraised/labeled/interpreted; and how we label is based on cultural/individual differences
E–>appraisal–>physio and emotion
Yerkes-Dodson Law
bells shaped curve- people perform best when they are moderately aroused
Moods
moods typically last longer than emotions
Appraisal Theory of Stress
Primary Appraisal= assess stress as positive/benign, stressful/negative, or irrelevant
Secondary Appraisal=material preparedness to deal with stressor-harm, threat, challenge (how to overcome it)
Categories of Stressors
significant life changes
catastrophic events
daily hassles
ambient stressor ( pollution)
Stress and Endocrine Response
adrenal glands release E and NE ( catecholamines) and cortisol
Tend and befriend and Stress
sometimes response to have support systems - Oxytocin is important for this ( peer bonding, strongly linked to estrogen)
General Adaptation Syndrome
1-alarm phase ( dip from normal health)
2-resistance ( flee, huddle, cortisol)
3-exhaustion -if resistance isn’t followed by recovery, our tissues become damaged and we become susceptible to illness
Physical Effects of Stress
CAD, hypertension, vascular disease due to high BP ( blood vessels become distended, build up more muscle and become more rigid and has spots that attract fatse)
Metabolism- body increases cortisol and glucagon which can lead to DM; cortisol also tells body to use fats as soruce of energy
Reproduction-infertility and impotence cause E and P, LH, FSH, and Testosterone inhibited
Immune Function- causes inflammation, acute stress can lead to overuse of immune system and attack own bodyor suppressed
Hippocampus and Frontal Cortex and Stress
have glucocorticoid receptors for cortisol, so affects memory and learning and executive function/behavior
Anhedonia
inability to experience pleasure, so perceive more stress
Depression and Serotonin

optimism
social support
Managing Stress

Upper Motor Neuron Tracts
corticospinal tract ( to spine) and corticobulbar tract ( to brainstem)
Frontal Lobe
motor, PFC, Broca’s area
Parietal Lobe
somatosensory cortex, spatial manipulation
Occipital Lobe
vision, “striate cortex” - cells are striated
Temporal Lobe
sound, Wernicke’s area
Cerebellum
coordinates movement - motor plan info is sent to cerebellum
also receives position sense information ( from muscle stretch fibers) adn sends feedback to cerebrum and motor areas of teh cortex
topically organized
Brainstem
midbrain, pons, medulla
connects brain together
HR, breathing, cross over point ( reticular formation)= acts as a filter which extends to thalamus(relay center), arousal ( alert and aware)
Long tracts
collections of axons connecting cerebrum and brainstem
2 long tracts that are important - motor (UMNs) and somatosensory
Cranial Nerves
most of cranial nerves are attached to the brainstem, doing many things; 12 pairs, all sorts of functions
Internal capsule
contains many important pathways, including corticospinal tract
Basal ganglia
major role in motor functions
sensory
thalamus- sensory functions travel through here; also high functions of brain such as cognition and emotion, part of diencephalon
Glutamate
+
most common excitatory neurotransmitter; reticular activating system, required for consciousness
GABA ( CNS)
Glycine (spinal cord)
most common inhibitory NTs
Acetylcholine
nuclei in frontal lobe that release called basilis and septal nuclei
released for LMNs, and the ANS
Histamine
hypothalamus sends it to cerebral cortex
NE (+)
area in PONS called locus ceruleus that releases it
Serotonin (-)
raphe nuclei in midbrain/medulla release it all over brainstem
Dopamine (+)
VTA and substantia nigra projects dopamine to other parts of basal ganglia called the striatum -> Parkinson’s
-dopamine of VTA –> PFC/Cort(-) via mesocortical path for negative symptoms of schiz

serotonin
Brain Structure imaging
CAT/CT scan and MRI
Brain Function Imaging
EEG
MEG/SQUIDS
PET scan
detail of structure, but combine them with CT scans and MRIs- inject glucose and see what areas are most active
fMRI
blood flow usign radioactive label/oxygen
Temperment
-characteristic emotional reactivity, sociability
established and persists, fairly “hardwired”; not samae as personality, broader than personality; seems to be established before babies are exposed to environment
Personality
constant over a person’s lifetime
Hertibility
variability of traits can be attributed to differences in genes
the percentage of variation of traits due to genes
as environment becomes more controlled, differences in behavior traits are more closely tied to heredity and heritability of that trait
h^2= 99% – if boys have same environment, any differences in IQ are 99% or 100% heritable cause environment was 100% same
h^2 = 0% if different environments and identical babies
Innate behavioral traits
reflexes
orientation ( kinesis, taxis)
fixed action pattern (performed without interruption)
Evolutionary Theory
role instincts play in motivation - basic instincts humans have - cry and sleep
Drive Reduction Theory
drives vs needs; need is lack or deprivation that will energize the dirve, or aroused state; that drive is what will reduce the need so can maintain homeostasis
Optimum arousal theory
people want to reach full arousal/alertnesse
Cognitive Theory
thought processes drive behavior
Maslow’s hierarchy of Needs
we need to satisfy needs in a particular order; physio, safety, love, self-esteem then self-acutalization
Incentive theory
calls attention to factors outside of individuals/extrinsic motivators that drive action; lead to repeat behavior, reinforce for increased future frequency
Theory of Planned behavior
we consider the implications of our intentions before we behave- intentions are based on 3 things:
attitudes towards a certain behavior, subjective norms, and perceived behavioral control
Attitude to behavior process model
an event triggers our attitude and then attitude +outside knowledge together determines behavior
Prototype Willingness Model
behavior is a function of 6 things: past behavior, attitudes, subjective norms, our intentions, our willingness, and prototypes/models of behavior
Elaboration Likelihood Model for persuasion on behavior
focus on why/how of persuasion
central vs peripheral
Justification of Effort
people do something they don’t want to justify effort they put into it
Cognitive Dissonance and modifications
2+ conflicting ideas, beliefs, values, or emotional reactions –> feeling of discomfort
4 things to reduce discomfort: DAMT
D- Deny the facts
Add-adding more cognition
Modify our cognitions-“I don’t really smoke that much”
T-Trivialize-make evidence or information less important
Attribution
process of inferring causes of events/behaviors; can be internal or external
3 parts - consistency, distinctiveness, and consensus
Suspensory ligaments
attached to ciliary muscle-these two things together form the ciliary body, which secretes the aqueous humor
Macula
special part of retina rich in cones
Fovea
in center of macula, only cones, no rods
Choroid
pigmented black in humans, a netowrk of blood vessels; because black, all light is abosrbed
sclera
whites of eye, thick fibrous tissue covers posterior 5/6th of eyeball; attachement point for muscles, lined with conjunctiva
Rods and Phototransduction cascade
120 million
rods are 1000x more sensitive to light than cones
Black and White vision
slow recovery time ( takes a while to adjust to the dark)
found mostly in periphery
night vision, light comes in, turns off rod ( cis to trans retinal) so that it no longer secretes glutamate and so turns ON bipolar cell which turns on ganglion cell which goes itno the optic nerve and enters the brain
Cones
6-7 million cones
3 types: red, green, blue
almost all cones are centered in fovea - high resolution at fovea cause no axons in way of light like restof eye (if light hits periphery it has to go through bundle of axons and some energy lost- so at fovea, hit light cones directly)
fast recovery time
Makeup of photoreceptor
rhodopsin or other opsin - a multimeric protein with 7 discs which contains a small molecule called retinal (11-cis retinal) which changes conformation to trans when hit with light
then transducin which is multimeric breads from rhodopsin and alpha comes to disk and binds to phosphodiesterase (PDE) a disk protein, PDE takes cGMP and converts it to regular GMP and then Na+ channels which need cGMP begin to close and Na+ decreases as cGMP decreases – so glutmate is no longer released ( since rods hyperpolarized now) and bipolar cells are ON which then activates retinal ganglion cell
Photopic vision
high levels of light - cones
Mesopic vision
dusk or dawn-both rods and cones
Scotopic
very low light levels - rods
Blind Spot
where optic nerve connects to retina, there are no cones or rods
Trichromatic Theory of color vision
Form – parvocellular pathway; good spatial poor temporal
Motion-magnocellular; high temporal,poor spatial, no color
Color-cones
Parallel Processing
see all at same time; detect/focus all information ( color, motion, form) at same time
Audition- HAS MIS
hammer, anvil, stirrup
malleus, incus, stapes
Place Theory/ Basilar Tuning
our perception of sound depends on where each component frequency produces vibrations along the basilar membrane
Apex = 25 Hz low frequency Base = 1600 Hz high frequency
Organ of Corti
includes basilar membrane and tectorial membrane ( lower and upper membrane)
hair bundle on each cell, each filament called a kinocilium, and tip of each kinocilium is connected by a tip link whith is attached to gate of K channel and so movement causes K+ to follow into cell which then causes Ca to get activated and go in and generate an AP in a spiral ganglion cell which then activates the auditory nerve to primary auditory cortex
Tonotopical Mapping
primary auditory cortex is also sensitive to various frequencies in different locations, so with basilar tuning, brain can distinguish diff frequencies and map them to different regions of the aud cortex
Sensory Narrow Hearing loss aka nerve deafness
Cochlear implants!
sound –> mic –> speech processor –> transmitter –>receiver –> stimulator –> cochlea which converts electrical impulse into neural impulse that goes to brain
key of audition
amplification - upregulation of intensity of sound as opposed to sensory adaptation
Proprioception
sense of balance/position; cognitive
tiny sensors located in our muscles that goes up to spinal cord and to the brain so we’re able to tell how contracted or relaxed every muscle in our body is
Kinaesthesia
talking about movement of the body; behavioral
*does not include snse of balance, while proprioception does
Types of Fibers - 3; A-B, A-D, A-C
A-beta: fast, thick and covered in myelin ( less resistance, high conductance)
A-delta: smaller diameter, less myelin
C fibers: small diameter, unmyelinated ( lingering sense of pain)
Temperature receptor
TrypVI receptor
pain also- capsaicin binds
Gate Control Theory of olfaction
“fast blocks slow
theory of the processes of nociception - asserts that non-painful input closes the “gate” of painful input which prevents pain sensation from traveling to the CNS so stimulation by non-noxious input is able to suppress pain
Olfaction
olfactory epithelium –> to olfactory sensory cells –separating the olfactory epithelium from the brain is the cribriform plate–
olfactory bulb is the brain region which is above cribriform plate, it is a bundle of nerves that sends little projections through the plate into the olfactory epithelium, which branch off= at the end of each connection are receptors which are sensitive to one type of molecule; molecule binds, will trigger APwhich will end up in olfactory bulb in a special region specific to that type of molecule called a glomerulus which then synapses on a mitral/tufted cell which projects to the brain
Labeled-Line Theory
scenario where each receptor would respond to specific stimuli and is directly linked to the brain
***smell does not synapse at thalamus, so stays IPSILATERAl
Vibrational Theory
vibration frequency of each molecule gives it its specific odor profile
Steric Theory/Shape Theory
odor fits into receptors similar ot lock and key
Vomeronasal System
within the accessory olfactory epithelium, where basal cells and apical cells are located
basal cells send axon thorugh olfactory bulb to glomerulus and then mitral/tufted cell, which eventually goes to amygdala
we have this but no accessory olfactory bulb
Gustation tastes
Bitter -GPCR Sweet- GPCR Salty ( NaCl) - ion channel Sour (H+) - ion channel Umami
Taste Buds
Fungiform( anterior-most), Foliate(side), and Circumvallate ( back)
each taste bud are the 5 receptor cells that can detect each taste; each taste be detected anywhere on the tongue
Gustation
each receptor has an axon which will remain separate until the brain, where all synapse on different parts of gustatory cortex
Sleep Stages
BATS Drink Blood ( lower frequency as progress); 4 stages that occur in 90 minute cycles
Non-REM N1 - theta, hypnagonic, hallucinations, tetris, hypnic jerks
Non-REM N2 - theta + sleep spindles and K-complexes, deeper sleep, harder to wake, memory consolidation
Non-REM N3- Slow Wave Sleep;walking/talking happens here; declarative memory consolidation
REM-muscles are paralyzed, dreaming, memory consolidation best here, alpha, beta and dysynchronous waves, paradoxical sleep cause brain is active; waking up during REM prevents memory formation of dream
Freud and Dreaming
dreams are our unconscious thoughts and desires that need to be interpreted; they have MEANING and help us resolve and identify conflict; little scientific support
manifest content-monster chasing you
latent content- job pushing you out
can help us resolve and identify hidden conflict
Evolutionary Biology and Dreaming
threat stimulation, to prepare for real world
problem solving
no purpose- stream of consciousness
Activation Synthesis Hypothesis of Dreaming
brain gets a lot of neural impulses in brainstem, which is sometimes interpreted by the frontal cortex
brainstem = activation; cortex =synthesis
our brain is simply trying to find meaning from random brain activity, therefore might not have meaning
N3 crazy
sleep apnea
sleepwalking/sleep talkin
Obstructive Sleep Apnea
obstruction to airways causes problems breathing at night; feel tired/sleep when wake up
measure with polysomnography
Cetnral Sleep Apnea
presence of apneas without obstruction, problem with control system for ventilation
Cheyne-Stokes breathing- period of oscillations, then flat pattern in polysomnography
Hypoventilation and Lungs
in lungs or chest wall, can occur ( high CO2, low O2) , caused by medication/obesity
chronically elevated pCO2 can lead to right-sided heart failure
Dissociation Theory of hypnotisim
hypnotism is an extreme form of divided consciousness
*hypnotism has more alpha waves
Social influence theory of hypnotism
people do and report what’s expected of them, like actors caught up in their roles
Meditation
training people to self-regulate their attention and awareness
increased attention control ( goal of mediation)
PFC, hippocampus, right anterior insula activation
Deprassants
alcohol, barbiturates, benzodiazepines
disrupt sleep, decrease CNS, BP, processing speech, reduced memory, judgement, concentration
prescribed for anxiety and sleep problems
Benzo- enhance brain’s response to GABA
Opiates
Heroin, Morphine, oxycodone, hydrocodone NOT depressants reduce pain by act at body's receptor sites for endorphins decrease CNS, BP, vasodilation, constrict pupils analgesic ( decrease perception of pain) natural- opiates synthetic-opiods lead to euphoria so taken recreationally
Stimulatns
Caffeine, Nicotine, Cocaine, Amphetamines and methamphetamines
stimulate, inc CNS, BP, alertness, asodilate, jittery, inc glucose metabolism
Caffeine- inhibits adenosine receptors which disrupts sleep
Nicotine-disrupts sleep and suppress appetite ( at high levels it can cause muscles to relax and release stress-reducing nts ( to counteract the hyper alertness)
addicting, withdrawal like insomina, irritible, anxiety
Cocaine-releases so much serotonin, dopamine ( blocks dopamine reputake) and NE that it depletes body’s supply so intense crash and very depressed when wears off; regular users can experience suspicion, convulsions, respiratory arrest and cardiac failure
Amphetamines and Methamphetamines - increase release of dopamine (prevent reuptake), euphoria, highly addictive, long-term addicts lose ability to maintain normal level of dopamine
Hallucinogens
ecstasy, LSD, marijuana, mescaline, peyote, PCP, psilocyobin (mushroom)
cause altered/disordted perception, may types of hallucinations
ecstasy- mix of stimulant and hallucinogen - inc OR dec Energy, inc BP, dilate pupils, dehydration, overheat, die, inc dopamine and serotonin for euphoria, inc CNS, hallucinations and heightened sensations, social connectedness feeling
LSD-interferes with serotonin, hallucinations which are VISUAL ( not auditory)
Marijuana - mild hallucinogen, active chemical is THC which heightens sensitivity to sounds, tastes, smells
reduces inhibition like alchol, impairs motor and coordination skills, disrupts memory formation and short-term recall
THC can stay in body up to 3 months in fat cells
tolerance can increase amoutn needed for impairment, used as medicine to relieve pain and nausea
Routes of Drug Entry
Oral-slowest
Inhalation- breathing or smoking
Injection- most direct, right to vein, v dangerous, most abused; injected drugs have higher addiction potential
Transdermal-skin, nicotine patch, released into bloodstream over several hours
Intramuscular- stuck in muscle, can deliver drugs to your system slowly or quickly - epipen or vaccines = fastest route
Reward Pathway in the Brain
when first experience pleasure, brain releases neurotransmitter called dopamine which is produced in VTA in midbrain
VTA sends dopamine to amygdala, nucleas accumbens, PFC, and hippocampus ( nAcc, amygdala, and hippocampus are part of mesolimbic pathway)
different stimuli activate circuit to different degrees
(increase dopamine, decrease serotonin ( which signals satiety))
Tolerance
you get used to a drug so you need more of it to achieve the same effect
-long term stimulation can lead brain to shut down some receptors so same amount of drugs won’t cause same high
Withdrawal
if go through a period of not having the drug, you experience withdrawal symptoms; stronger with stronger drugs
once you’ve built up tolerance, need the drug to feel “normal” again
BUT with time and effort, brain can reverse back
-2 stages: acute and post-acute
acute- few weeks, physical symptoms, vary from person to person ; for alcohol only 2 days after cessation can experience this
Post-acute: fewer physical, more emotional and psychological; same for everyone
Cross Tolerance
reduction in the efficacy or responsiveness to a novel drug due to a common CNS target
Intoxication
behavioral and psychological effects on the person, drug-specific
Post-Acute Withdrawal Symptoms (PAWS)
can last 2 years
mood swings, anxiety, irritability, low enthusiasm
roller coaster and each episode lasts about a few days
Methadone
treat opiate addiction, activates opiage receptors too but acts more slowly so dampens high and eases withdrawal
Cognitive Behavioral Therapy (CBT)
addresses both cognitive and behavioral components of addiction
recognize problematic situations and develop more positive thought patterns and coping strategies, and monitor cravings
anticipate problematic situations like partys with drugs
Motivational Interviewing
working with patient to find intrinsic motivation to change
Group meetings
like AA, 12 step program
Relapse
when patient can slip and go back – more addictive substances make relapse more likely, why it’s hard for people to stay clean
Covert Orienting
bring spotlight of attention to somethign without body or eye
Overt Orienting
person turns all or part of body to alter or maximize sense of stimulus
Attentional capture
when attention is attracted by motion of an object or stimulus
Executive Attention
involved in goal-oriented behavior ( dopamine and VTA)
Neglect Syndrome
damage to brain causes loss in capacity of spatial dimension of divided attention
Orienting Attention
capacity to change focus - ACh and basal forebrain ( includes nuAcc, septal nuclei, and nucleus basilis
Divided attention
switing between tasks rather than doing them simultaneously
Directed Attention
allows attention to be focused sustainably on a single task
Selective Attention
ability to maintain attention while being presented with masking or interfering stimuli; when you switch your attention, you’re exercising your selective attention ( like a flashlight, at any given moment illuminating one area of interest)
Types of Cues
exogenous- don’t have to tell ourselves to look for them, but they are external to any goals - bright colors, loud noises
endogenous-require internal knowledge to understand the cue and the intention to follow it; cocktail party effect ( ability to concentrate on one voice amongst a crowd or when someone calls your name)
Inattentional/perceptual blindness
we aren’t aware of things not in our visual field when our attention is directed elsewhere in that field
Change Blindness
we fail to notice changes in environment ( between previous and current state)
Shadowin task
hearing test- left ear hear one thing, right ear another thing then told to repeat everything said in one ear and ignore the other; all about selective attention
Braodbent’s Early Selection Theory
all information in environment goes into sensory register –> selective filter –> perceptual process –> other cognitive processes
prob- if completely filter out unattended info, shouldn’t identify your own name in unidentified ear like in Cocktail party effect
Deutch & Deutch’s Late Selection Theory
places broadband selective filter AFTER perceptual processes – selective filter decides what you pass on to conscious awareness but everything is assigned meaning
sensory register –> perceptual processing –> selective filter –> other cognitive processing
Treisman’s Attenuation theory
instead of complete selective filter, we have an attenuator - weakens but doesn’t eliminate input from unattended ear and then assign meaning to stuff in unattended ear, just not high priority
sensory register –>attenuator –> perceptual processes –> other cognitive processes
Spotlight Model of Attention
selective attention- takes information from 5 sense, but doesn’t pay attention to everything
we are aware of things on an unconscious level
depends on priming
Resource Model of Attetion
we have limited resources in attention
both models say something about oru ability to multitask - not very good at it
Ability to Multitask/Divided Attention based on
task similarity- harder to multitask with similar tasks
Task difficulty-harder tasks require more focus ( drive in new area)
Practice- activities well practiced become automatic, or things that occur without need for attention ; whether task is automatic or controlled (harder)
Sanctions
rewards/punishments for behaviors in accord with or against norms
can be formal or informal
Folkways
mildest type of norm, like manners of opening door
Mores
norms based on moral value/belief like not lying
Laws
based on right and wrong and have formal consequences
Taboos
completely wrong in any circumstance and violation results in consequences that are extreme, like cannabilism
Deviance
violating a norm
Theory of Differential Association
deviance is a learned behavior that results from continuous exposure to others that violate norms and laws- learn from observation of others
Labeling Theory
a behavior is deviant if people have judged that behavior and labelled it as deviant
