PSYCH CARDS Flashcards
Kurt Lewin
- developed the theory of association, the forerunner of behaviorism
- association is grouping things together based on the fact that they occur together in time and space.
- organisms associate certain behaviors with certain rewards and certain cues with certain situations
- this idea is basically what Pavlov later proved experimentally
Walden Two and Beyond Freedom and Dignity
- books written by Skinner
- discusses the control of human behavior rather than rat behavior
Instrumental conditioning
another name for operant conditioning
Who created balance theory
-Fritz Heider
Who created congruity theory
Charles Osgood and Percy Tannenbaum
Who created cognitive dissonance theory
Leon Festinger
Victor Vroom
- Applied Tolman’s Performance= Expectation X Value to individual behavior in large organizations
- individuals who are lowest on the totem pole do not expect to receive company incentives, so these carrots do little to motivate them
John Atkinson
- suggested a theory of motivation in which people who set realistic goals with intermediate risk sets feel pride with accomplishment, and want to succeed more than they fear failure.
- But, because success is so important, these people are unlikely to set unrealistic goals or to persist when success is unlikely
Yerkes Dodson effecr
- in terms of arousal, simple tasks have the optimal arousal toward the high end
- for complex tasks, the optimal level of arousal is toward the low end, so that the individual is not too anxious to perform well
- the optimal arousal for any type of task is never at the extremes
- on a graph, the optimal arousal looks like an inverted U-curve, with lowest performance at the extremes of arousal
Undergeneralization
-the failure to generalize a stimulus
Response learning
-the form of learning in which one links together chains of stimuli and responses. One learns what to do in response to particular triggers
Perceptual or concept learning
- learning about something in general rather than learning-specific stimulus-response chains. An individual learned about something rather than any particular response.
- ex: Tolman’s rats’ cognitive maps
Automatic conditioning
-evoking responses of the automatic nervous system through training
State dependent learning
-what a person learned in one state is best recalled in that state
Social learning theory
-individuals learn through their culture. People learn what are acceptable and unacceptable behaviors through interacting in society
John Garcia
- performed classical conditioning experiments in which it was discovered that animals are programmed through evolution to make certain connections
- studied “conditioned nausea” with rats and found that invariably nausea was perceived to be connected with food or drink
- he was unable to condition a relationship between nausea and a neutral stimulus.
- this extremely strong connection that animals form between nausea and food has been used to explain why humans can become sick only one time from eating a particular food and are never able to eat that food again
- the connection is so automatic, so it needs little conditioning
- called the Garcia effect and especially strong in children
Positive transfer and negative transfer
- previous learning that makes it earlier to learn another task later (positive)
- previous learning that makes it more difficult to learn a new task (negative)
Educational psychology
- concerned with how people learn in educational settings
- examines things like student and teacher attributes and instructional processes in the classroom
- educational psychologists are frequently employed by schools and help when students have academic or behavioral problems
Cooperative learning
-involves students working on a project together in small groups
Surface structure v deep structure
- surface: the way that words are organized
- Deep: the underlying meaning
Reading and Writing (similarly processed in the brain as what)
-processed in the same regions of the brain as producing and understanding speech
-Whorfian hypothesis
- has been used as an argument for the importance of nonsexist language
- But, it has been found that culture that don’t have words for certain colors can still recognize them, so it is unclear to what extent language really affects our perceptions
Vygotsky and Luria
- Russia’s best known psychologists
- studied the development of word meanings and found them to be complex and altered by interpersonal experience
- they asserted that language is a tool involved in (not just a byproduct of) the development of abstract thinking
Charles Osgood
- studied semantics (word meanings)
- created semantic differential charts, which allowed people to plot the meanings of words on graphs
- results showed that people with similar backgrounds and interests plotted words similarly
- this indicated that words have similar connotations (implied meaning) for cultures or subcultures
George Sperling
- found that people could see more than they can remember.
- in his classic experiment, subjects were shown something like this (GRPZ, ILTH, TBAE) for a fraction of a second
- then, they were instructed to write down letters of a particular line
- although they were able to do this, they invariably forgot the other letters in the time it took to write the first ones down
- this partial report shows that sensory memory exists, but only for a few seconds
Order of items on a list
-in a recall test involving the order, subjects can more quickly state the order of two items that are far apart on the list than two items that are close together
tachtiscope
- an instrument often used in cognitive or memory experiments
- presents visual material (words or images) to subjects for a fraction of second
mediation
- the intervening mental process that occurs between stimulus and response
- reminds us what to do or how to respond based on ideas or past learning
Semantic effect
- logical reasoning error
- believing in conclusions because of what you know or think to be correct rather than what logically follows from information given
Decision making
- working on solving a problem until an acceptable solution is found
- research indicated that the process of reaching a solution is usually based on some sort of assumption, which could either be rational or irrational, and the solution is usually found by relying on reasoning and/or emotion.
Cognitive-theory of emotion
-another name for the Schachter-Singer theory of emotion
Reception
- takes place when receptors for a particular sense detect a stimulus
- the receptive field if the part of the worlds that triggers a particular neuron
Sensory transduction
- the process in which physical sensation is changed into electrical messages that the brain can understand.
- at the heart of the senses
Structuralist theory of perception
- asserts that perception if the sum total of sensory input
- the world is understood through bottom-up processing
Perceptual development (James Gibson)
- the increasing ability of a child to make finer discriminations among stimuli
- the optic array, or all of the things a person sees, trains people to perceive
What is light composed of
-photons and waves measures by brightness and wavelengths
Ciliary muscles
-alls the leans to bend (accommodate) in order to focus an image on the outside world onto the retina
What is the retina composed of
-about 132 million photoreceptor cells and of other cell layers that process information
Receptor cells
- rods and cones
- on the retina are responsible for sensory transduction.
- this happens through the chemical alteration of photopigments
What happens after light passes through the receptors
- travels through the horizontal cells
- to the bipolar cells
- to the amacrine cells
- some information processing probably takes place along the way
- finally, the information heads to the ganglion cells, which make up the optic nerve
Optic Chiasm
- half of the fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye
- this, the pathways are 50% crossed
- this ensures that input from each eye will come together for a full picture in the brain
- after the optic chiasm, the information travels through the striate cortex to the visual association areas of the cortex
Where do the opponent-process theory and the tri-color theory take place
- opponent-process theory seems to be at work in the lateral geniculate body
- tri-color theory seems to be at work in the retina
lateral inhibition
- allows the eye to see contrast and prevents repetitive information from being sent to the brain
- this complex process is the idea that once one receptor cell is stimulated, the others nearby are inhibited
Hubel and Wiesel
-discovered that cells in the visual cortex are so complex and specialized that they respond only to certain types of stimuli
figure and ground relationship
-refers to the relationship between the meaningful part of a picture (the figure) and the background (the ground)
McCollough effect (afterimages)
are perceived because of fatigued receptors
Dark adaptations
-the result of regeneration of retinal pigment
Mental sets
-factor into why we see what we expect to see
Minimum principle
-the tendency to see what is easiest or logical to see
Purkinje shift
- the way that perceived color blindness changes with the level of illumination in the room
- with lower levels of illumination, the extremes of the color spectrum (especially red) are seen as less bright
Pattern recognition
-most often explained by template matching and feature detection
Weber’s law
- applies to all senses but only to a limited range of intensities
- states that a stimulus needs to be increased by a constant fraction of its original value in order to be notices as noticeably different
Fechner’s law
- built on and more complicated than Weber’s law
- the strength of a stimulus must be significantly increased to produce a slight difference in sensation
J.A. Swet’s Theory of Signal Detection (TSD)
- subjects detect stimuli not only because they can but also because they want to
- factors motivation into the picture, which changes the idea of purely mathematical equations and explains why subjects respond inconsistently
- partly motivated by rewards and costs in detection
- this is response bias
Receiver operating characteristics (ROC) curves
-graphical representations of a subject’s sensitivity to a stimulus
Timbre
-comes from the complexity of the sound wave
Traveling wave
movement on the basilar membrane
Vestibular sacs
- also respond to hair movement
- sensitive to tilt and provide our sense of balance
Receptor cells in the inner ear
-activate nerve cells that change the information into an electrical message that the brain can process
Auditory system that leads to the auditory cortex
- olivary nucleus
- inferior colliculus
- medial geniculate body
Sound localization
- achieved in different ways
- the degree to which one of our ears hears a sound prior to and more intensely than the other can give us information about the origin of the sound
- high-frequency sounds are localized by intensity differences, whereas low-frequency sounds are localized by phase differences
Dichotic presentation
- often used in studies of auditory perception and selective attention
- subject is presented with a different verbal message in each ear
- subjects are asked to shadow, or repeat, one of the messages to ensure the other message is not consciously attended to
Meissner’s corpuscles
-receptors in skin that detect tough or contact
Pacinian corpuscles
-touch receptors that respond quickly to displacements of sin
Size of two-point threshold for touch
-largely determines by the density and layout of nerves
Melzack and Wall’s Gate Control Theory of Pain
- looks at pain as a process rather than just a simple sensation governed in one center in the brain
- assert that pain perception is related to the interaction of large and small nerve fibers that run to and from the spine
- pain may or may not be perceived depending on different factors, including cognition
Endorphins
-neuromodulators that kick in to reduce or eliminate the perception of pain
Simulations
-use perceptual cures to make artificial situations seem real
Subliminal perception
-perceiving a stimulus that one is not consciously aware of
osmorereceptors
-deal with thirst
Cortical association areas
-the larger the area, the more sensitive and highly accessed is the corresponding function
Stereotaxic instruments
-used to implant electrodes into animals’ brains in experiments
Neuromodulators
-are like neurotransmitters, but they cause long-term changes in the postsynaptic cell
REM sleep
- also known as paradoxical sleep
- in this state, beta waves and a person’s physiological signs (heart rate, etc) resemble those in a waking state, but muscle tone decreases to the point of paralysis, with sudden twitches, especially in the face and hands
- lasts from 15 minutes at the beginning of a sleep cycle to 1 hour at the end of it
rebound effect
- occurs when people are deprived of REM sleep
- they will compensate by spending more time in REM sleep later in the night
Sleep cycles
- people complete 4-6 each night
- each cycle lasts about 90 minutes
- early in the night, most of the time is spent in Stage 3 and 4 sleep
- Stage 2 and REM sleep predominate later on in the night
Comparative psychology
- closely related to ethology
- through research studies, different species are compared in order to learn about their similarities and differences
- psychology draws from animal studies to gain insight into human functioning
Queen bee
- constantly tended to and fed by all other bees (female working bees)
- in the spring, she lays thousands of eggs
- as these eggs mature, scouts find a new hive site for the old queen and her workers
- when a new queen is ready to emerge in a hive, the old queen and her crew depart for a new site
Kohler chimp experiment
- chimps only had to use tools (long sticks) or create props (stack boxes) to retrieve rewards
- only through insight could the chimp accomplish this
Psychoanalytic theory
- views conflict as central to human nature
- conflict is that between different drives (particularly conscious and unconscious) vying for expression
- individual is motivated by drive reduction
- originally, freud said that an individual’s greatest conflict was that between libido and the ego
- later, said that the true conflict is that between eros (life instinct, including love and sex) and thanatos (the death instinct, including self-destructive behavior)
- “the aim of all life is death”
- initially, freud preferred a topographic model of mental life in which conscious elements were openly acknowledged forces and unconscious elements, such as drives and wishes, were many layers below
- later, freud said the model of mental life was structural, meaning that mental life has particular organization other than layers
Psychoanalytic abnormal theory
- he often worked with women who were hysterical or neurotic
- he said these conditions and other abnormal ones were the result of repressed drives and conflicts, which become manifested in dysfunctional ways
- pathological behavior, dreams, and unconscious behavior are all symptoms of underlying, unresolved conflict, which are manifested when the ego does not find acceptable ways to express conflict (this ic called psychic determinism)
Psychoanalytic therapy
- seen four to five times per week
- used hypnosis (borrowed from Charcot and Janet) and free association (developed by Breuer)
- this discharge of emotion is called catharsis or abreaction
- object relations therapy: when the therapist uses the patient’s transference to help him or her resolve the problems that were a result of previous relationships by correcting the emotional experience in the therapist-patient relationship
Goal of psychoanalytic therapy
- aims to lessen the unconscious pressures on the individual by making as much of this material conscious as possible
- this allows the ego to be a better mediator of forces
Criticisms of psychoanalytic theory
- Freud has been criticized for his methodology
- developed theories from single case studies of women
Aggression
central force in humans that must find a socially acceptable outlet
reaction formation
- defense mechanism
- embracing feelings or behaviors opposite to the true threatening feelings that one has
Compensation
- defense mechanism
- excelling in one are to make up for short comings in another
Sublimation
- defense mechanism
- channeling threatening drives into acceptable outlets
Identification
- defense mechanism
- imitating a central figure in one’s life
Undoing
- defense mechanism
- performing a ritualistic activity in order to relieve anxiety about unconscious drives
Manifest v Latent content in dreams
manifest: the actual content of dreams
latent: the unconscious forces the dreams are trying to express
Screen memory
-memories that serve as representations of important childhood memories
Individual Theory (Alderian theory)
- Alfred Adler
- people are viewed as creative, social, and whole as opposed to Freud’s more negative and structural approach
- described people in the process of realizing themselves or in the process of “becoming”
- during this journey, the person is motivated by social needs and feelings of inferiority that arise when the current self does not match the ideal self
- a healthy individual pursues goals in spite of feelings of inferiority, has the a “will to power” or quest for feelings of superiority
- on this quest, a healthy individual will pursue goals that are outside of himself and beneficial to society
Abnormal theory of individual theory
- unhealthy individuals are too much affected by inferior feelings to pursue the will to power
- they make excuses or have a “yes, but” mentality.
- if they do pursue goals, these are likely to be self-serving and egotistical
Therapy in individual theory
- a psychodynamic approach in which unconscious feelings do play a role
- more importantly, is the examination of a person’s lifestyle and choices
- a patient may examine his own motivations, perceptions, goals, and resources
Goals of therapy in individual theory
-aims to reduce feelings of inferiority and to foster social interest and social contributions in patients
Criticisms of individual theory
-best used with “normal” people in search of growth
Adler’s personality typology
- based on personal activity and social interest
- ruling-dominant (choleric): high in activity but low in social contribution, dominant
- getting-learning type (phlegmatic): low in activity and high in social contribution, dependent
- avoiding type (melancholic): low in activity and low in social contribution, withdrawn
- socially useful type (sanguine): high in activity and high in social contribution, healthy
Analytical Theory
- Jung
- felt that Freud places too much emphasis on libido
- postulated that the psyche was directed toward life and awareness (rather than sex)
- in each person, the psyche contains conscious and unconscious elements
- the unconscious is divided into two types: personal and unconscious
- the archetype: universally meaningful concepts, passed down through the collective unconscious since the beginning of man; allow us to organize our experiences with consistent themes and are indicated by cross-cultural similarity in symbols, folklore, and myths
