Ap Psych - Unit 8 - Intelligence andTesting questions with actual answers.
standardization ANS - defining meaningful scores by comparison with the performance of a pretested
group.
- to enable meaningful comparisons, tests-makers first give the test to a representative smaple oof
poeple
- same test, same timing, same space.. everyone treated THE SAMe.
- standarized tests result in a bell shaped curve
random sample ANS - every person in group group has equal chanve to participate . large is better than
small
normal curve ANS - symmetrical, bell shaped curve that describes the distribution of many psychological
attributes. most scores fall near the average, and fewer lie near the extremes
flynn effect ANS - intelligence test perofmrane has been imporving worldwide throught the last century.
worldiwde pheneomenon
reliability ANS - -consistency
- the extent to which a tests yields consistent results , as assesed by the consistency of scores on two
halves of the test or on retesting
- to check a tests reliability, we retest people
-ex) a broken scale, gives same wight everyday soo its reliable but not VALID.
test-retest reliability ANS - to check a tests reliability, we retest people
restandardized ANS - to keep the stanford-binet and Wechsler scales near 100, scales are periodically
----.
, validity ANS - the extent to whih a test measures or predicts what it is supposed to. measures what it is
designed to measure
ex- if you usa an inaccuratr measurer to find height, the height report would have high reliability but low
validity
content validity ANS - the extent to which a test smaples the behavior that is of interest
ex) drivers license test
predictive validity (criterion-related validity) ANS - the success with which test predicts the behavior it is
designed to predict; it is assessed by computing the correlation between test scores and the criterion
behavior
correlation coefficients ANS - statistical index of the relationship b/w two things. how either one
predicts the other (from -1 to +1)
- ex) aptitude tests scores correlate with school success tells how well the scores predict school success
- little to no correlation has a 0
-positive correlation = study time with grade received
negative correlation = amount of absences and your grade
standard deviation ANS - how much scores deviate (vary around) the mean score (average)
there is a modest positve correlation with brain size and intelligence scores
- highly educated people die with more synapses
- highly intelligent people differ in their nearual plasiticty
-higher intelligence scores were linked with more gray matter (neaural cell bodies) and white matter
(axons and dendrites)
- frontal lobe becomes active when asked verbal/spatial questions ANS - is intelligence neuroligically
meaurable??
perceptual speed ANS - those who perceive very quickly tend to score somehwat higher on intelligence
