Dichotomous thinking
black and white thinking (e.g. "if I don't score 100% I have no future")
Cognitive Theory (therapy)

Gestalt Theory (goal of therapy)
Perls, Wetheimer, Koffka; goal is exploration of awareness and full experiencing of the present; success is connecting client with present existence
Gestalt Theory (criticisms)
Perls, Wetheimer, Koffka; not suited for low-functioning or disturbed clients
Existential Theory (originator)
Victor Frankl
Existential Theory (description)
Frankl; revolves around philosophical issues particularly the issue of meaning; one`s greatest struggles are being vs. nonbeing, and meaningfulness vs. meaninglessness; individual constantly strives to rise above a simple behavioural existence and toward a "will to meaning"

Antimanics
drugs for bipolar disorder, mania appears to be from excessive monoamines; inhibit monoamines such as norepinephrine and serotonin (ex. Lithium)
Antidepressants (+types)

Konrad Lorenz
founder of ethology, imprinting, animal aggression, releasing stimuli, fixed action patterns
Imprinting
Lorenz, certain species (often birds) young attach to first moving object they see, "following response", sensitive learning period: doesn't matter what their later experiences are
Animal aggression
Lorez, certain aggression necessary for survival of species, instinctual rather than learned
Releasing stimuli
aka releasers or sign stimuli, Lorenz, continued by Tinbergen, elicits fixed action patterns from another individual in the same species
Fixed action patterns
Lorenz, triggered by releasing stimuli, automatic and innate, instinctual, complex chains of behaviour; four defining characteristics: uniform patterns, performed by most members, more complex than simple reflexes, cannot be interrupted
Nikolaas Tinbergen
models in naturalistic settings, stickleback fish and herring gull chicks
Stickleback fish
Tinbergen, males develop red coloration on belly, which is the releasing stimulus for attacks; males attacked red-bellied crude models rather than the detailed but non-red models
Herring gull chicks
Tinbergen, peck at end of parents' bills which have a red spot on the tip, parents then regurgitates food for chicks; chicks pecked more at a red-tipped model bill than at a plain model bill; the greater the contrast between bill and red spot even when unnaturally strong; supernormal sign stimulus
Supernormal sign stimulus
Tinbergen, artificial stimuli that exaggerate naturally occurring sign stimulus or releaser, more effective than natural

Karl von Frisch
dance of the honeybees, and also studied senses of fish
Communication of bees
von Frisch, once a scouting bee locates a promising food source, returns to hive and conveys the location through movements; round or waggle dance, the longer the dance the farther the food, the more vigorous display the better food; performed on vertical sheets of the hive where the angle is a vertical line and direction of bee orients when dancing is the same angle as between sun and food sources; also communicates potential nesting sites
Round dance
bees dance to indicate food is extremely nearby
Waggle dance
bees dance to indicate food is far away
Navigation of bees
scouting bees look for food and nesting sites; can use landmarks as simple location cues, also sun, polarized light, and magnetic fields as aids

Infrasound
pigeons can hear extremely low-frequency sounds (e.g. emitted by surf) that travel great distances as a navigational cue
Magnetic sense

Star compass
many birds can use star patterns and movements as navigational cue
Polarized light
when sun is obscured by clouds, bees can use this navigational cue to infer sun positioning
Echolocation

arrangement of words into sentences as prescribed by a particular language
Grammar
overall rules of relationship between morphemes and syntax for a certain language
Morphology/ morphological rules
grammar rules' how to group morphemes
Prosody
Tone inflections, accents, and other aspects of pronunciation that carry meaning
Noam Chomsky
psycholinguistics; transformational grammar; language acquisition device (LAD)
Transformational grammar
Chomsky, differentiates between surface structure (way words are organized; 3 different sentences) and deep structure (what it means; could mean the same thing)
Language acquisition device (LAD)
Chomsky, innate ability to learn language; children made small errors based on grammar rules rather than large structural errors; seems they only need exposure to a language to easily use LAD, not through imitation, memory, or conditioning; genetic interpretation
Overregularization
overapplication of grammar rules (e.g. "I founded my toy")
Overextension
generalizing names for things, chaining characteristics rather than logic (e.g. any furry thing is a "doggie")
Telegraphic speech
speech without articles or extras like a telegram (e.g. "Me go")
Holophrastic speech
using one word (holophrases) to convey a whole sentence (e.g. "me" for "give that to me")
Girls (language learning)
Gender that learns faster and more accurately in language
Bilingual children (language learning)
These children learn language slower
Reading and writing (language learning)
processed in same brain regions as producing and understanding speech, but slight differences suggested by alexia and agraphia while having no speech problems
First phrases spoken (language learning)
children use nouns first then verbs, usually one noun and one verb (e.g. "me want") or two nouns (e.g. "mommy shirt")
Language acquisition milestones
1 year speaks first word(s), 2 years > 50 spoken words, usually 2 then 3-word phrases, 3 years 1000-word vocabulary but has grammatical errors
Benjamin Whorf
Whorfian hypothesis; from studying Hopi, language or how a culture says things influences perspective, used for argument for non-sexist language; however cultures that don't have certain colors can still recognize them, so unclear the extent language affecting our perceptions
Roger Brown
social, developmental, linguistic psychology found children's understanding of grammar rules develops as they make hypotheses about how syntax works and then self-correct with experience
Katherine Nelson
language development begins with onset of active speech rather than during the first year of only listening
William Labov
"Black" English, Ebonics, has its own complex internal structure, not simply bad English
Lev Vygotsky and Alexander Luria
Russian psychologists, development of word meanings are complex and altered by interpersonal experience (communicating with significant people in their lives to learn cultural habits); also, language is a tool in developing abstract thinking (not only byproduct)
Charles Osgood
semantics (word meanings), semantic differential charts
Semantic differential charts
Osgood, plot meanings of words on graphs, people with similar backgrounds and interests plotted words similarly, indicating words have similar connotations for cultures/subcultures
Learning
relatively permanent or stable change in behaviour as the result of experience
E. L. Thorndike
law of effect
Law of effect
Thorndike, cause-and-effect chain of behaviour; continue what rewards, stop what doesn't
Kurt Lewin
theory of association
Theory of association
Lewin, grouping based on co-occurence in time and space; associate certain behaviours with certain rewards and cues
Ivan Pavlov
classical conditioning
Classical conditioning
Pavlovian conditioning; teaching a response (relationship) to neutral stimulus by pairing with not-so-neutral stimulus
Neutral Stimulus (NS)
does not produce a specific response on its own (e.g. light or bell)
Unconditioned Stimulus (UCS)
not-so-neutral stimulus, elicits response without conditioning (e.g. salivation)
Conditioned Stimulus (CS)
neutral stimulus once paired with UCS; no naturally occurring response, only with UCS pairing (e.g. light (CS) eventually produces salivation)
Unconditioned Response (UCR)
naturally occurring response (e.g. salivation to food)
Conditioned Response (CR)
Response that CS elicits after conditioning; UCR and CR will be the same (e.g. salivation)
Simultaneous Conditioning
UCS and CS presented at the same time
Higher-Order conditioning
previous CS now a UCS (e.g.*bell > [ light > food > ] salivation)
Second-Order conditioning
previous CS now a UCS (e.g.*bell > [ light > food > ] salivation)
Forward Conditioning (types)
delayed conditioning and trace conditioning
Delayed conditioning
type of forward conditioning; CS before UCS, lasts until UCS presentation
Trace conditioning
type of forward conditioning; CS presented and terminated before UCS presentation
Backward Conditioning
CS presented after UCS (e.g. food, then light); proven ineffective; accomplishes only inhibitory conditioning, harder time pairing CS with UCS later even with forward conditioning
Types of classical conditioning
simultaneous, higher-order/second-order, delayed forward, trace forward, backward
John B. Watson
school of behaviourism
Behaviourism
Watson, everything explained by stimulus-response chains, developed by conditioning; only objective and observable elements important
B. F. Skinner
operant conditioning
Operant conditioning
Skinner, instrumental conditioning; behaviour primarily influenced by reinforcement strategies, do what rewards, not what doesn't
Skinner box
empty box (with a rat and a lever), later proved the influence of reinforcement
Shaping
differential reinforcement of successive approximations; Skinner rewarded rats first for being near lever then for touching it, reward for behaviours that brought them closer to the desired one (e.g. pressing lever)
Differential reinforcement of successive approximations
shaping; Skinner rewarded rats first for being near lever then for touching it, reward for behaviours that brought them closer to the desired one (e.g. pressing lever)
Primary Reinforcement
natural reinforcement, without requirement of learning; food and water
Secondary Reinforcement
learned reinforce, often through society; money, prestige, rewards
Positive Reinforcement
reward or positive event that increases likelihood of a particular response
Negative Reinforcement
removal of a negative event that increases likelihood of a particular response; while punishment introduces a negative event to decrease likelihood of a response
Continuous Reinforcement Schedule
every correct response is met with reinforcement; quickest but most fragile learning, as soon as rewards stop coming, the animal stops performing
Partial Reinforcement Schedule (+types)
not all correct responses met with reinforcement; slower but more resistant; fixed ratio, variable ratio, fixed interval, variable interval; variable is best because it is unexpected, ratio gives better response since based on # of correct behaviours
Fixed ratio schedule
reinforcement delivered after a consistent number of responses; vulnerable to extinction
Variable ratio schedule
most time to learn but least likely to be extinguished; reinforcements are delivered after different numbers of correct responses, ratio cannot be predicted
Fixed interval schedule
rewards after a certain period of time rather than number of behaviours; can be argued that it does little to motivate an animal's behaviour
Variable interval schedule
rewards delivered after differing time periods; second most effective strategy in maintaining behaviour
Token economy
individuals in the environment are motivated by secondary reinforcers; e.g. tokens in prisons, rehab, etc., cashed in for more primary reinforcers (e.g. candy, books, privileges)
Basic types of drives
primary/instinctual (hunger or thirst), secondary/ acquired (money or other learned reinforcers), exploratory (seek novelty or explore)
We are primarily motivated to maintain physiological or psychological homeostasis. Example theories and problem?
Fritz Heider's balance theory, Charles Osgood and Percy Tannenbaum's congruity theory, Leon Festinger's cognitive dissonance theory; what about individuals who often seek stimulation, novel experience, or self-destruction?
Fritz Heider's balance theory
attitude change, based on balance of "sentiment" or liking relationships, if the net affect valence multiplies out to a positive result
Charles Osgood and Percy Tannenbaum's congruity theory
associative or dissociative attitudes on 7pt scale toward objects
Leon Festinger's cognitive dissonance theory
drive to reduce cognitive dissonance, holding conflicting ideas simultaneously whether beliefs, attitudes, or actions
Drive-reduction theories
born with certain physiological needs, will be tension if not satisfied; when it is, return to state of homeostasis and relaxation
Clark Hull
Performance = Drive x Habit; will do what has worked in the past to satisfy drive
Edward Tolman
Performance = Expectation x Value; expectancy-value theory; goals they expect they can meet and how important goal is
Victor Vroom
applied expectancy-value theory to individual behaviour in large organizations (e.g. those lowest on totem pole have least motivation since little incentives)
Henry Murray, David McClelland
need for achievement (nAch); need to pursue success or to avoid failure
John Atkinson
those who set realistic goals with intermediate risk feel pride with accomplishment, and want to succeed more than they fear failure
Neil Miller
approach-avoidance conflict; state felt when a goal has both pros and cons, typically focus on pros when far from goal, cons when close to goal
Hedonism
motivation by what brings most pleasure and least pain
Premack principle
motivated to do what they do not want to do by rewarding themselves afterwards with something they like to do
Donald Hebb
medium amount of arousal best for performance
Yerkes-Dodson effect
higher arousal for simple tasks (motivation), lower arousal for complex tasks (concentration); optimal arousal is an inverted U on a graph
Stimulus discrimination
ability to discriminate between different but similar stimuli
Stimulus generalization
opposite of stimulus discrimination; make same response to a group of similar stimuli (e.g. fire alarms may sound different but same response)
Undergeneralization
the failure to generalize a stimulus
Response learning
links together chains of stimuli and responses, learns what to do in response to particular triggers
Perceptual/conceptual learning (+example)
learning about something in general for knowledge rather than learning-specific stimulus-response chains (e.g. Tolman's experiments with animals forming cognitive maps of mazes rather than simple escape routes)
Aversive conditioning
punishment to decrease likelihood of a behaviour
Avoidance conditioning
how to avoid something undesirable
Escape conditioning
teach performance of a desired behaviour to get away from a negative stimulus
Punishment
promotes extinction of undesirable behaviour, negative stimulus presented after behaviour to decrease likelihood of reoccurrence
Autonomic conditioning
evoking responses of autonomic nervous system through training
State dependent learning
what a person learns in one state is best recalled in that state
Extinction
reversal of conditioning, dissociating behaviour from a cue
Spontaneous recovery
reappearance of an extinguished response, even without further conditioning
Latent learning
takes place without reinforcement, knowledge not immediately expressed, e.g. learning while watching
Incidental learning
accidental learning, unrelated items grouped together; opposite of intentional learning (e.g. dog associates car with vet)
Superstitious behaviour
"learning" that a specific action causes an event, when in reality the two are unrelated
Chaining
linking a series of behaviours that result in reinforcement, one behaviour triggers the next (e.g. learning the alphabet)
Habituation
decreasing responsiveness to a stimulus due to increasing familiarity
Sensitization
increased sensitivity to environment after exposure to a strong stimulus
Overshadowing
inability to infer a relationship between a stimulus and response due to the presence of a more prominent stimulus
Autoshaping
by having an apparatus (e.g. lever), an animal controls its reinforcements (e.g. food) through behaviours (e.g. pressing), shaping its own behaviour
Social learning theory
learn acceptable and unacceptable behaviours through culture
Observational learning
learning by watching
Modeling (+example?)
learning by imitation; Albert Bandura's Bobo doll (children watching adults with blow up dolls)
John Garcia
preparedness, that certain associations are learned more easily than others; animals programmed to make certain connections; Garcia effect - nausea associated with food
Garcia effect
animals strongly and automatically connect nausea and food, especially strong in children; preparedness
M.E. Olds
electrical stimulation of pleasure centers in the brain used as positive reinforcement, evidence against drive-reduction theory
Drive-reduction theory
motivation to reduce internal tension, once satisfied, back to homeostasis/ relaxation; against M.E. Olds electrical stimulation of pleasure centres
Continuous motor tasks vs. discrete motor tasks
continuous motions easier to learn, once started continues naturally; discrete divided into parts and do not facilitate recall of each other
Positive transfer
previous learning helps learning of another task later
Negative transfer
previous learning makes learning a new task more difficult
Age affects learning
learn 3-20, constant 20-50, drops 50+
Hermann Ebbinghaus
learning curve
Learning curve
Ebbinghaus, when learning something new, rate of learning usually changes over time; can be positively or negatively accelerated

how people learn in educational settings such as student and teacher attributes
Thorndike (book)
credited with writing first educational textbook in 1903 to assess students and teaching
Aptitude
set of characteristics indicative of one's ability to learn
Cooperative learning
students working on a project in small groups
Scaffolding learning
teacher encourages independent learning, only provides assistance when needed
