Aptitude testswhat your potential. IQ, Asvab, Reflex
Achievement testshow much you've learned AP, SAT, Classroom tests.
Binet and Terman's testsdesigned to identify children who might have difficulty in school. mental age/chronological age X 100 (10 year-old with mental age of 12 year-old scores 120). measured reasoning skills. best measure for younger children
WAIS(Wechsler Adult Intelligence Scale) Verbal & performance scores. Most widely used intelligence test today
WISC(Wechsler Intelligence Scale for Children) Verbal & performance scores. Most widely used intelligence test today
Factor analysisIdentifies clusters of closely related test items
Standardized testsIQ scores form a Normal curve, with a score of 100 as the mean and a 15pt standard deviation
ReliabilityThe extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting.
Validitydo scores measure what they are intended to measure?
Predictive validitydoes the test accurately predict the behavior it is designed to predict?
Content validitydoes the test measure the content of interest?
Savant syndromecondition in which a person otherwise limited in mental ability has an exceptional specific skill
Downs Syndromeextra #21 chromosome
Mental retardationtypically have intelligence scores below 70; can range from mild to profound
When people are creativeThey have a wide base of knowledge about the subject. They have imaginative thinking skills. They have an adventuresome personality. ****They are intrinsically motivated (extrinsic motivators make people less creative!)
Crystallized Intelligencethe ability to use skills, knowledge, and experience
Fluid Intelligencethe ability to solve new problems. It is the ability to draw inferences and understand the relationships of various concepts, independent of acquired knowledge
Emotional Intelligence1. Perceive emotions: tell what others are feeling 2. Understand emotions recognizing, predicting emotions, how they blend together. (anger+love=jealousy) 3. Regulating emotion: ability to keep emotions in check, Keep from melting down, getting anxious, angry; using emotions in a productive, self-helping way.
Verbal/Linguistic IntelligencePerson who loves to play with language, good at remembering names, places, dates, and similar. Learn through language
Logical/Mathematical IntelligenceLearner likes to figure things out by asking questions, exploring, and doing some experimenting. Good at math, classifying, categorizing, and working out relationship abstractions.
Visual/SpatialPerson who enjoys drawing, designing, and looking at pictures, slides, videos, and films
Music/RhythmicHummer of tunes, singer of songs, probably plays an instrument, is always listening to music. Person excels at remembering melody, noticing the rhythms of life, and keeps perfect time.
Body/KinestheticPerson in motion; touching while talking, and using the body to express ideas. Learning has a kinetic component; interacting with space in some way so as to process, and remember, the new informatoin through the body.
InterpersonalThe joiner; always with a group of people and talking with friends. Leading others, organizing, mediating, communicating and understanding people and how to work well with them.
IntrapersonalPerson does better alone; purusing self defined interests. Excels at 'knowing' himself, follows instincts with confidence, and is an original. new information is absorbed best when the projects are individual, self-paced, and singularly organized.
AlgorithmA methodical, logical rule or procedure that guarantees solving a particular problem. Contrasts with the usually speedier-but also more error-prone-use of heuristics
HeuristicA simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than algorithms.
InsightA sudden and often novel realization of the solution to a program; it contracts with strategy-based solutions
Confirmation biasa tendency to search for information that confirms one's preconceptions
PrototypeA mental image or best example of a category. Matching new items to the prototype provides a quick and easy method for including items in a category (as when comparing feathered creatures to a proto-typical bird, such as a robin).
Functional fixednessThe tendency to think of things only in terms of their usual functions; an impediment to problem solving.
Representativeness heuristicJudging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes; may lead one to ignore other relevant information.
Availability heuristicEstimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common.
FramingThe way an issue is posed; how an issue is framed can significantly affect decisions and judgments
Analytical intelligenceAssessed by intelligence tests, which present well-defined problems having a single right answer. Such tests predict school grades reasonably well but predict vocational success more modestly.
Creative intelligenceDemonstrated in reading adaptively to novel situations and generating novel ideas.
Practical intelligenceRequired for everyday tasks, which may be ill-defined, with multiple solutions. Managerial intelligence, skills at writing effective memos, motivating people, delegating tasks and responsibilities, reading people
General intelligence (G)A general intelligence factor that, according to Spearman and others, underlies specific mental abilities and is therefore measured by every task on an intelligence test.
HeritabilityThe proportion of variation among individuals that we can attribute to genes. The heritability of a trait may vary, depending on the range of populations and environments studied.
Identical twins reared togetherHighest similarity of intelligence scores out of twins and siblings
Identical twins reared apart (shows some environmental effect)Second highest similarity of intelligence scores out of twins and siblings.
Fraternal twins reared together (shows genetic effects)3rd highest similarity of intelligence scores out of twins and siblings.
Siblings reared together4th highest similarity of intelligence scores out of twins and siblings.
Unrelated individuals reared together5th highest similarity of intelligence scores out of twins and siblings.
Head start programChildren quality program, offering individual attention, increases children's school readiness. But aptitude benefits dissipate over time (reminding us that life experience after the program matters too).
intelligence test biastest-takers expectations, stereotype threat, content validity - on whether it predicts future behavior only for some groups of test-takers, if the test detects performance differences caused by cultural experiences
VariationHow similar or diverse the scores are
RangeThe difference between the highest and lowest scores in a distribution
Standard deviationa computed measure of how much scores vary around the mean score
Normal curveA symmetrical, bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean (68 percent fall within one standard deviation of it) and fewer and fewer near the extremes.
Correlation coefficientA statistical measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. Its marked with "r"
Statistical significanceHow likely it is that an obtained result occured by chance. It does not indicate the importance of the result.
Central TendencyMode (frequently occurring score of scores), mean (arithmetic average), median (the middle score.
Positively skewed distributionHump is to the left
Negatively skewed distributionHump is to the right
VarianceThe mean of all squared deviations from the mean
How to calculate standard deviationExtract the square root of the variance. If the variance is 16 the SD is 4
68%Percentage within 1 standard deviation
95%Percentage within 2 standard deviations
99.7%Percentage within 3 standard deviations.
Behaviorismbased on the proposition that all things which organisms do — including acting, thinking and feeling—can and should be regarded as behaviors
Socio-cultural Psychologyfield of psychology which assumes the idea that culture and mind are inseparable, thus there are no universal laws for how the mind works and that psychological theories grounded in one culture are likely to be limited in applicability when applied to a different cultur
Myelin Sheatha layer of fatty tissue segmentally encasing the fibers of many neurons, vastly greater transmission speed of neural impulses
Agonist (neurotransmitter)excites neurons & increases firing by mimicking a neurotransmitter or blocking reuptake
Parkinson's Diseasecaused by dopamine deficits in the brain (movement circuit). degenerative disorder of the central nervous system that often impairs the sufferer's motor skills and speech
Color constancythe tendency for a color to look the same under widely different viewing conditions
Accommodationthe process by which the eye's lens changes shape to focus neat or far objects on the retina
Sensory interactionthe principle that one sense may influence another, as when the smell of food influences its taste
GestaltThe experience that comes from orgainizing bits and pieces of information into meaningful wholes
Perceptual constancyperceiving objects as unchanging (having consistent lightness, colour, shape and size) even as illumination and retinal images change
Sensory deprivationthe deliberate reduction or removal of stimuli from one or more of the senses
Classical conditioningwhen an animal or person learns to associate a stimulus with a reinforcement or aversion
extinctiona conditioning process in which the reinforcer is removed and a conditioned response becomes independent of the conditioned stimulus
Schedules of reinforcementthe rule for determining when and how often reinforcers will continue; Four types of schedules: fixed ratio, variable ratio, fixed interval, and variable interval; interval means over a time and ratio means an act; partial reinforcement is on a variable schedule whereas continuous reinforcement is on a fixed schedule; variable schedules are more effective in learning
Bandura theory of social learningPeople learn through observing others' behavior, attitudes, and outcomes of those behaviors. (Bobo doll)
Episodic memoryPart of explicit/declarative memory that stores memories of personally experienced events; a mental diary of a person's life
Implicit memorymemory retrieval in which there is no awareness of remembering at the time of retrieval
Proactive interferenceAn item is interfered with by information you have previously learned
retroactive interferencethe disruptive effect of new learning on the recall of old information
Chomsky's theory of languagechildren have innate, language-specific abilities that facilitate and constrain language learning
Linguistic relativityThe hypothesis that the language a person speaks is related to his or her thoughts and perceptions
Catharsis hypothesisreleasing aggressive energy relieves aggressive urges
Insulina hormone that lowers the blood glucose level
