MEASUREMENT AND METHOLOGY Flashcards
MEAUREMENT AND METHODOLOGY
- assessment behaviours, attitudesm mental constructs personality, and mental health
Intelligence
- mental construct specifically defined
- intelligence is NOT IQ
- IQ is score of inteligence
- unlikely that IQ captures all intelligence
Alfred Binet
- developed IQ and first IQ test (Binet Scale) = mental age/chronological age x 100
- Intelligence stops developing after age 16
Mean IQ of Americans
- is 100
- SD = 15 or 16
Stanford Binet Intelligence Scale
- revised version of Binet’s intelligence test
- best known predictor of future academic achievement
Lewis Terman
- from standford university and revised the Binet Intelligence Scale
- studies of children with higher IQ are better adjusted (gifted children)
Weschler Adult Intelligence Scale (WAIS)
- most commin IQ test for dults
- organized by subtests
Wescler Intelligece Scale for Children (WAIS-R)
- for children age 6-16
Wechsler Preschool and Primary Scale of Intelligence (WPPSI)
- for children age 4-6
Goodenough Draw a Man Test
- notable for cros cultural application an simple directions to draw the very best picture
- are marked via detial and accuracy, not talent
IQ correlates mostly with who?
- biological parents and socioeconomic status of parents (income or job type)
John Horn and Cattell
- found fluid intelligence decines with old age and cyrstaliized intelignece does not
Robert Zajonc
- relationship between birth order and intelligence
- firstborns more intellignece than 2nd
- greater spaces between children = higher intelligence
Charles Spearman
- general factor in human intellignece called “g”
Achievement test
- measure how well you know a particular subject
- measure past learning
Aptitude test
- meaure your innate ability
- predict future perofmrance
Objective test
- subects can’t make own answers, are already structure
Structure test
- more objectively scored than projective tests
- most are self-reported (but still subject to response bias)
Q-sort, Q-measure techniques
- process of sorting cards into normal distrbution
- each card with a personality statmente and neutral ones and place at the hump and definind or undefining cards are put into the sides
Mineesota Multiphasic personality Inventory (MMPI)
- OG for mental illnes but now a peronality meaure
- T/F questions
- items to discriminate between different disorders
- high validity becau of items and 3 validity scales (lying, carelessness, faking)
California Personality Inventory (CPI)
- use for more “normal” and less clinical groups
Myer-Briggs Type Indicator (MBTI)
- derived from Jung’s personality theory (archetypes)
- 2 answer per question then given 4 letter personality type
1) introvert/extravert
2) sensing/intuition
3) feeling/thinking
4) judgment/perception
Julain Rotter
- creater internal/external locus of control
Projective tests
- subjects to create own answer through expression of conflicts, need, impulses
- content is interpreted by administrators
- some may be score objectively
Rorschach Inkblot Test
- subject desrcibe what they see in 10 inkblot
- complex scoring
- questionable validity
Thematic Apperception Test (TAT)
- cards of interpersonal scences are shown and subject tells story of each card to reveal personality
- used to measure need for achievmenet
- needs, press, persnology are terms with test
Reosenweig Picture Frustration (p-F) stud
- cartoons where 1 person is frustrating the other
- subject ask to describe how frustated person responds
Word Association Test
- used in conjucnction with free association tecniques
- word called out, subject says next word that comes to mind
Rotter Incomplete Sentence Blank
- similar to word association
- subject finish sentences
Draw a Person Test
- asks subject to draw a person of each sex and tell a story about them
Beck Depression Inventory (BD)
- not to diagnose depression but for severity of depressive symptoms and track course of symptoms
Empirical-keying or criterion keying approach
- constructing assessment instruments invovles selection of items that discriminate between various groups
- response determines if person is in particular group or not
- e.g. Strong-Campbell Interest INventory
Vocational Test
- what extent individual’s interest and strengths match those already found by professionals in particualr job field
Lie detector test
- measure arousal of sympathetic nervous system which becomes stimulated by lying (and anxiety)
walter Mischel
- critical of personality trait-theory and personality tests in general
- felt situations decided actions (not traits)
Anne Anastasi
- researched intelligence in relation to performance
F-scale or F-ratio
- measurement of facism or authoritarian personality
Bayley Sclaes of Infant Developent
- not intelligene tests
- mesure senory/motor development of infants to identify mentally retarded children
- poor predictors of later intelligence
Research design
- how research attempts to examine hypothesis
- differnt quetions = different approachs
- some are called more scientific than others
Scientific approach to psychology involves (3)
1) testable hypothesis
2) reporductible experiment can be replicated
3) operationalized defintiion of concept under study
Field study
- takes place in naturalistic setting
- less control over enviornment
- generates more hpyothesis than can be proved
Experimental design
- takes place in controlled setting
- draw causal conslusions from experiment
IV
- manipulates IV by applying it in experimental or treatment condition by withhodling if from the control condition
DV
- does not control the dependent variable but examineshow IV effects the DV
Confounding variable
- attempts to minimize or eliminate confounds
- variables in environment that might also affect DV and blue effect of IV on DV
Sample or subgroup
- drawn from population bc is impossible to include all members
- sample must be representative of population and unabiased
Random sampling
- applied to achieve representative population and unbias sample
- every member of population has an equal chance of getting chosen
Conviencance sampling
- used when random sampling is not possible e.g. a group of psych students
Stratified sampling
- to make results more generalizable then convienanc sampling
- aims to match emographic characteritcs of sample to demographics of population
Longitudinal design
- studying same objects at differnt points in lifespand and provides better, mored valid result than most other methods
- time consuming
Cross-sectional design
- different subjects of different ages are compared
- faster, easier than longitudinal
Cohort-sequential design
- combines longiudeninal and cross-sectional approaches
Within-subjects
- test same person at multiple time points and looks at chnges within person
Between-subject design
- compares 2 groups of ppl at the same time point
Quasi-experimental esign
- compares 2 groups of people but design is used when it is not feasible/ethical to use random assignment e.g. you cannot assign one group to smoke for 20 years
Double-blind
- experiments when neither subject nor experimenter knowns whether subject is assigned treatment or control
